Fusion FNC 로고

퓨전FNC 하면 개인적으로 공CD, 공DVD 취급 업체로 각인이 되어 있는 곳입니다. 한창 애니메이션에 심취했을 때 공DVD 천여 장에 차곡차곡 백업을 해두던 때가 새록새록. 지금은 다양한 컴퓨터 액세서리를 취급하는 업체로 사업영역이 확대되어 있는데, 그 취급품목 중 하나가 Flaircomm이란 브랜드의 블루투스 장비입니다. 이번 리뷰에서는 퓨전FNC에서 판매하고 있는 BT-i4M 블루투스 모노 무선헤드셋을 살펴보기로 하겠습니다.

1. 제품의 인상

첫 인상이 나름 충격적이었습니다. 디자인 모티브가 100% 아이폰4에서 얻었다는 것을 자랑스러운 듯이 보여주고 있기 때문입니다. 홈페이지의 제품 소개에서도 "애플 스타일 디자인"임을 강조하고 있지요. "직관적 인터페이스" 부분은 모르겠지만. 그러고 보니 제품 이름이 i4M이군요. iPhone 4 Mobile?

작동 중인 Fusion FNC Flaircomm BT-i4M 본체

애플이 블루투스 헤드셋도 만들었다면 스티브 잡스가 단번에 "너 고소!" 할지도 모르겠다는 생각입니다. 참고로, 이 제품은 중국 Kiss Communications Technology가 만든 BTK-718의 OEM 제품인 것으로 보이므로 고소장이 나온다면 이 회사로 먼저 가지 않을까 싶군요. 어쨌든, 지금 제가 가지고 있는 아이폰4와는 상당히 잘 어울리는 편이라 법적인 문제야 어떻든 간에 점수를 따고 들어 갑니다.

디오텍 AllThatMobile OCR 베타 리뷰 (2/2)

wesley96@gmail.com (Wesley) — Sat, 28 May 2011 22:14:15 +0900

디오텍이 새롭게 선보일 AllThatMobile OCR (이하 ATM)의 베타버전 리뷰 2부입니다. 못 보신 분은 리뷰 1부를 먼저 보시고 오세요. 여기서 기다리고 있겠습니다. 준비가 되신 분은 계속 읽어주세요.

3. 문서 인식기능

ATM으로 문서 인식하는 모습

인식영역 설정

메인 화면에서 "문서 인식" 아이콘을 누르고 아래처럼 인식할 문서를 카메라로 촬영하거나 이미 준비된 이미지를 불러들이면 됩니다. 방법은 명함 인식 때와 동일합니다.

이미지가 준비되면, 오른쪽에서 볼 수 있듯이 틀을 움직여 인식 영역을 지정합니다. 방법과 한계는 리뷰 1부에서 본 명함 인식 때와 거의 동일합니다. 명함 인식과 차이가 있다면, 인식 영역을 지정한 뒤 바로 서버에 전송하는 것이 아니고 문서를 받는 사람, 제목, 파일이름, 파일 형식, 인식 언어를 먼저 설정한다는 것입니다.

디오텍 AllThatMobile OCR 베타 리뷰 (1/2)

wesley96@gmail.com (Wesley) — Sat, 28 May 2011 22:07:00 +0900

AllThatMobile 로고

디오텍은 지난 번 디오딕 리뷰에서 보았듯이 모바일 기기의 필기 및 문자인식 분야에서 일가견이 있는 회사입니다. 최근에는 문자인식 영역으로 확대를 해가는 경향이 있는데, 현재 앱스토어 등에서 판매가 되고 있는 명함인식 앱인 모비리더(MobiReader)를 보더라도 알 수 있습니다. 이번에는 명함인식 뿐만 아니라 문서인식과 팩스전송까지 겸하는 종합 OCR(광학문자인식) 앱인 AllThatMobile OCR을 선보이려고 하고 있어서 베타테스트를 해봤습니다.

1. 기본 실행환경

시작부터 삐걱?

사용하게 된 AllThatMobile OCR (이하 ATM) 베타는 0.9.23 버전이며, 안드로이드 버전만 개발되어 있는 관계로 순정 프로요(안드로이드 2.2)가 설치된 공장초기화 상태의 모토로라 모토로이(Motoroi)에 설치하여 사용했습니다. 앱을 처음 실행시키면 계정 로그인 페이지가 뜨는데 (사실 맨 처음 본 것은 오른쪽과 같은 앱이 다운되는 화면이라 당황스러웠음 - 재시작하니 첫 화면을 볼 수 있었는데 아무래도 베타의 버그인 듯), 이것은 ATM이 일종의 온라인 서비스라는 것을 암시하는 것이었습니다. 앱 내에서 "계정 생성" 버튼을 누르면 간단하게 계정을 만들 수 있었으며, "자동 로그인"에 체크를 해두면 다시는 로그인 화면을 볼 필요가 없게 됩니다.

로그인이 된 상태라면, ATM이 제공하는 "문서 인식", "명함 인식", "팩스" 기능과, 그동안 작업했던 문서가 보관된 "문서함"의 아이콘이 나오며, 기기의 메뉴 키를 누르면 "알림"과 "설정" 메뉴가 나옵니다. 화면 구성은 너무 깔끔한 나머지 뭔가 부족한 듯한 느낌이 들 정도입니다. 특히, 모토로이가 다른 안드로이드 폰보다 화면이 아래로 약간 더 길어서 (800이 아닌 854 픽셀) 그런지 아래의 여백이 더 크게 와닿았습니다. 아이콘 크기를 좀 더 키워도 되었을 것 같았습니다.

iOS용 디오딕 뉴에이스 일한/한일사전 리뷰

wesley96@gmail.com (Wesley) — Mon, 13 Dec 2010 16:44:00 +0900

디오텍(Diotek)은 10여 년 전 PDA가 등장하던 시절부터 오랜 기간 동안 제품을 만들어온 회사로써, 스마트폰 붐이 일어나기 전에 모바일 기기를 접한 사람들 사이에서는 디오펜(DioPen) 입력기를 만든 회사로 잘 알려져 있기도 합니다. 요즘은 입력기 자체보다는 그동안 축적된 필기인식, 글자인식 기술을 바탕으로 각종 사전과 명함인식 프로그램을 제작하여 판매하고 있습니다. 이번에 리뷰를 하게 된 제품은 그 중 하나인 iOS용 "디오딕 뉴에이스 일한/한일사전"입니다.

1. 단어 검색 방법

사전의 내용은 뉴에이스가 일본 쇼가쿠간과 공동편찬한 종이사전 내용을 옮겨담은 것이므로 검증이 이미 되었다 생각하여, iOS용 앱으로써의 기능에 중점을 두어 평가해보기로 하겠습니다. 아이폰4, iOS 4.2.1이 설치된 상태를 기준으로 합니다. 먼저 단어검색 부분을 보면 아래와 같이 필기입력과 자판입력을 지원합니다.

iPhone 3GS camera's actual resolution

wesley96@gmail.com (Wesley) — Tue, 26 Jan 2010 16:06:00 +0900

The dizzying ISO 12233 Test Chart

Point-and-shoot digital cameras have reached the end of the 'megapixel race' at around 12 megapixels, giving you a photo with the resolution of 4000x3000. One of the reasons for this peak is that the typical image sensors used in this class can produce only around 10 megapixels of actual data at best, and even less with internal post-processing applied. As a result, camera's 'actual' resolution will be far less than 4000x3000, even if the 'output' resolution is that large. Increasing output resolution any higher without better sensors would be no better than doing a digital zoom - bigger picture without more detail.

A smart shopper would therefore avoid blindly following the megapixel number on the spec sheet, and instead check the sensor size as well as the actual sample images posted in independent product reviews. In many professional reviews, an ISO 12233 Test Chart(partly seen above) is used to check the actual resolution of a camera. DPReview has been extensively using it.

So, why am I talking about this 'actual' and 'output' resolution today? I carry a nice compact digital camera - Kodak Z1085 IS - and an excellent smartphone - iPhone 3GS - with me at all times. The image quality is good for the given class, and they have the maximum native output resolution of 3648x2736 (10MP) and 2048x1536 (3MP), respectively. But I suddenly got curious as to what their actual resolution would be. Unfortunately, searching the internet did not come up with any resolution testing - it was time to do a little testing of my own...

Optimus mini three + iRocks KR-6600

wesley96@gmail.com (Wesley) — Sun, 17 Dec 2006 01:39:53 +0900

The keys to my Mac

I've been using an interesting combo of input devices lately. Namely, Art Lebedev Studio's Optimus mini three keyboard (left) and I-ROCKS' KR-6600 'nano slim' keyboard. The two keyboards are relatively unique in that the mini three is the first keyboard to implement OLED displays for the keys, and that the KR-6600 is probably the smallest 'full set' keyboard you'll find on the market. It's barely bigger than the Half Keyboard I used for my wearable computer back in the old days.

The $14 MP3 Player disassembled

wesley96@gmail.com (Wesley) — Sat, 05 Nov 2005 19:39:00 +0900

Guts open

(Continuation of "The $14 MP3 Player")

Curious to find out what made this cheap MP3 player tick, I had to take it apart... carefully, of course, because I wanted to keep using it. You unscrew two tiny metal bolts, then have to unhinge the two plastic hooks that stick the top and bottom pieces together. The plastic hooks were a bit hard to get around, since it looked kind of easy to break. I did manage to do it without breaking anything, and the device revealed its innards.

The $14 MP3 Player

wesley96@gmail.com (Wesley) — Sat, 05 Nov 2005 17:00:15 +0900

Package arrives...

While Apple iPod is dominant in most of the world's portable MP3 player market, there are always some niche products scattered around. One such class is the MP3 players that are very cheap because they lack any on-board storage. They use the flash memory cards you plug in for the storage instead. If you somehow end up with a flash memory card left over doing nothing useful, these MP3 players may attract you, despite common sense telling you it's money wasted. Here's my story.

X501 vs M4300 in size

wesley96@gmail.com (Wesley) — Mon, 22 Aug 2005 00:41:00 +0900

M4300 was the smallest WM2003-based PDA-phone on the market before X501. X501 is even smaller. Let's see how they compare.

Because X501 has a smaller screen, it's immediately noticeable that the device is narrower than M4300.

Alpha PAL6035 vs Zalman CNPS3100-Gold (4/4)

wesley96@gmail.com (Wesley) — Thu, 11 Jan 2001 04:00:00 +0900

System Configuration

CPU:	AMD Duron 650@945 & AMD Athlon(T-bird) 750@1113
M/B:	Asus A7V (VIA KT133 chipset) - VIA 4-in-1 v4.27 -
Cooling:	PAL6035 & CNPS3100
RAM:	256MB x 1 OCZ PC150 CAS2 SDRAM
Video:	SUMA GeForce2 GTS 32MB - NVIDIA Det. v6.34 -
OS:	Windows 2000 - Version 5.00.2195 SP1, English -
Else:	Motherboard Monitor 5.03, Seventeam ST-301HR PSU

Update: Kyle of HardOCP is concerned that the temperature reading of Alpha you see here looks wrong. I'm quite aware of the situation and I do believe it is related to the A7V's temperature sensor being a bit inaccurate. But the readings have been quite reproduceable in this system, and since this can be seen as relative comparison, you can still validly determine which one is better.
Update 2: I've confirmed that my temperature reading is actually more representative of the truth since I use external temperature sensor attached directly to the core instead of using temperature sensor inside the CPU socket.

The Benchmark

Chart data was assessed by using interval log option of Motherboard Monitor in steps of 30 seconds for one hour of boot time, then entered into Microsoft Excel to produce the actual chart.

First test was done with Duron 650 overclocked to 945MHz. It is easily recognizable that CNPS3100-Gold pulls ahead of PAL6035 by a comfortable 2 degrees in normal mode. This means that, despite the fan's airflow is distributed to the mainboard in general instead of focused on the heatsink itself, CNPS3100 is effectively cooling the hot overclocked Duron with ease. Silent mode operation is another matter, though. Being 11 degrees higher than normal mode, it is unsuitable for overclocking. However, the fan was very quiet, so it can be useful in non-overclocked environments and CPUs that dissipate less heat than AMD chips, such as Intel Celeron.

Another round of tests were performed with 'Thunderbird' Athlon 750 running at notably high 1113MHz. The CNPS3100 again beats PAL6035, this time in a slightly larger margin. Silent mode of CNPS3100 could not be completed and was not listed here because it promptly caused halting of system within 10 minutes due to overheat.

Conclusions

The ambient temperature was closely monitored with thermometers such as this Hydro-Quebec thermometer that's been rolling around since my Canadian days and I've taken care to make sure that the temperature remained constant during testing to prevent measurement errors.

The verdict of this comparison is clear. While both heatsinks provide good cooling, CNPS3100-Gold comes out superior all the time, winning this round of match. Also, looking at the performance delta between CNPS3100 and PAL6035 and then comparing the results from other hardware sites, while the comparance may not be really so linear, we can safely assume that it can take on the all-copper 'hedgehog' cooler or the monstrous GlobalWin FOP38, both of which are currently taking the performance crown, pretty well. Since FOP38's delta fan is notorious for its near-unbearable noise levels, CNPS3100 with its low-noise fans may be a better alternative.

Finally, I end this review-comparison with testimony from 'Schpankme', a regular at MadOnion's forums and chatrooms(where I am working as a moderator) who is probably the first American to get his hands on the CNPS3100. Yes, I've shipped him the product personally because Zalman doesn't have foreign offices/distributors outside Korea. He is seeking to form a distributor of this product in the USA and I'll be attempting to arrange this with him imminently. Anyone who are interested may contact me.

Update 3: I have now set up international order page for this heatsink [HERE]. Those who were thinking of ordering Zalman heatsinks can rest easy now.

WDSoft,

Thought I'd drop you a quick update on my newly acquired FHS unit from Zalman. The quality is awesome, the size is just right and the clip is easy to install and remove, the fan bracket is a very useful idea for any HSF. I however am NOT impressed with the FAN that came with my unit, and wonder if it actually functions properly or is broke! I am plugging up with the 4-pin adapter, yet it barley puts out enough air to even feel it on your hand. I have replaced the fan with Sunon 80mm x 25mm, 12v, .16 amp, 2.0 watt, 4500 RPM, 36 CFM, 32 dBA, 3 pin. This fan is very quiet inside the case, and as you can see by picture attached to this email, it really does a lot for the cooling potential of this setup. The temps listed are for average usage, which consists of email, web-surfing, and Microsoft cards type game play. Load testing was accomplished using Prime95, ran for 24 hours in conjunction with other apps and games; and at NO times did my temps get above 40C. I must say I really enjoy my newly found prize, and I owe a big thanks to you for trusting me enough to order me one. Now your thinking to yourself, ok pank has a more powerful fan blowing substantially more air across the heat sink surface, so naturally it will be some what cooler. Well, yes you could think that, and it would be correct, but I have also disconnected my 2-side 92mm blow holes, and am running with full covers on the case. I also attribute my understanding of how to lap the Heat Sink, as well as applying the proper ratio of COPPER thermal compound before installation of Heat Sink to CPU Core.

Understand, I am in no-way holding you responsible for the units fan performance or the lack thereof. I would like to know if your fan has what I term the same lackluster performance. One last final note, I wasn't able to send you the sanding cloths we spoke of. It seems the store was out of the assorted packs, and just got them in today. I will however be mailing them off first thing Monday morning ad hopefully you will receive them a few days later!

Thank you again for making me aware of this fantastic FHS Gold-3100. I have decided to import these units into the States for sale, could you be of assistance in knowing the quantity and price breaks I could receive.

Blue Skies;

Schpankme Verimuch

Alpha PAL6035 vs Zalman CNPS3100-Gold (3/4)

wesley96@gmail.com (Wesley) — Thu, 11 Jan 2001 03:00:00 +0900

The Contender - Zalman CNPS3100-Gold

CNPS3100-Gold is a socket HSF from South Korea's Zalman Tech Co., Ltd.. This company is relatively unknown to the computing world because it is an upstart; it was founded in 1999 and started marketing their products for only around 10 months, generally limited to Korean markets. Their flagship product is the patented Flower HeatSink(FHS) as shown above. By forming the heatsink in the likes of a 'flower', it is meant to achieve effective cooling without a fast and noisy fan. This is the basis of their product concept, actually. CNPS in the name of the product stands for 'Computer Noise Prevention System'. This heatsink is the part of Zalman's line of products targeted for low-noise computer systems. Other products they market include FHS for video cards, NP(Noise Prevention) PSUs, and NP Hard Disks. They claim that noise-less computer systems can be built once the person uses all of the products Zalman provides in his/her system. Zalman does sell fully configured systems, also.

CNPS3100 is the latest in the product lines of the Zalman HSFs, just released in the December of 2000. You can read its news release here in Korean (English product page is here). Zalman has yet to revamp its site to provide multilingual support, so the English page is my translation of the Korean counterpart. FHS was initially made in aluminium with a few fins, but over time, to increase its cooling performance, the recent models are made in pure copper. Pure copper rusts over time, so the latest FHS included in CNPS3100 is coated in either pure gold or chrome to prevent rust. The model tested here is the more expensive(and good-looking) version, the CNPS3100-Gold. The Gold version costs about US$10 more than the Chrome coated version. The shape of the heatsink, the FHS, should no doubt be an eye-catcher for most of you.

It is without doubt that the shape of the FHS has intrigued a lot of people. Since it is supposed to operate with slow/silent fan or no fan at all while most heatsinks must have fast fans attached, either the company selling it is out of mind or the heatsink must possess cooling performance that is worth (literally) gold. Let's take a look at its key specs:

Specification
Dimensions(mm):	110 x 52 x 65
Mass (grams):	296
Cooling Fan:	Adda 80mm
Fan Speed(rpm):	3000 ~ 1500(Silent)
Fan Power(cfm):	38.6 ~ 20.2(Silent)
Thermal Resistance:	0.28 ~ 0.35(Silent) C/W

The specifications are already impressive. On their rated thermal resistance, it already beats Alpha PAL6035 in any mode. You will have to see the benchmarks to see if this claim can be backed up, but it would actually be a shame if this massive heatsink weighing in at 70% heavier wouldn't perform at least as good as the competitor. Now the thing that many of you are wondering would be in the form of, "where's the 80mm fan that's listed here? How are you going to install that on the contraption?" Read along and that will be answered.

CNPS3100's Packaging

The image on the left is the original package that CNPS3100-Gold comes in. In case you're wondering what those words at the left-top corner are supposed to say, it means, "Powerful... Silent..." Open the box and you see the contents, as shown on the right. You get the instruction booklet(all in Korean just yet), the heatsink itself, and the clip to attach it on(see left of the heatsink). Like PAL6035, it also comes with thermal paste. It comes in an easy-to-use syringe rather than tube, however. At the bottom of the box, you see the fan that was not seen in the initial photo attached to a metal holder with two sets of screws for attaching the holder onto the system case. Just how is all this going to fit into a system? Watch.

CNPS3100 Installation

Installing the FHS part of the CNPS3100-Gold is not unlike installing a normal heatsink. Put the clip into the FHS(it slides into place) and push the right edge of the clip to snap on. You can use a flathead or philips screwdriver to help installing/uninstalling it, for there are holes on the clip to accomodate such things. Now comes the peculiar part you'll never see while installing conventional heatsinks. Cooling fan comes attached on a metal holder, which is in turn installed onto the case. This is obviously because the FHS does not have a place to attach fans on(actually, fans can be installed directly onto FHS with a small adaptor screwed in place, but Zalman has no plans to market the adaptor yet). You attach the holder by unscrewing top three screws holding the expansion cards, putting the holder in, and screwing them back.

You may notice two things of concern here. For one, the fans don't seem to be aligned with the heatsink well. This is not to worry, as the cooling performance is not affected by the location of the fan once it is almost as close to the FHS as shown in the picture. This is mentioned in the instruction booklet and I have moved around the fans closer/farther and confirmed this. In fact, the cooling fan is intended to double as the northbridge chipset fan, so the installation shown in the picture is rather optimal. You can see the northbridge covered in a small green heatsink below the FHS in the left picture. This chip gets very hot during operation and since most mainboards do not actively cool this important chip, CNPS3100's fan setup is well thought up.

Another concern is that the metal holder leaves no room for installing case fans. This is not so much of a trouble because you can simply attach the case fan on the opposite side to provide same case cooling.

The two heatsinks looks fine now, but how do they really perform?

Alpha PAL6035 vs Zalman CNPS3100-Gold (2/4)

wesley96@gmail.com (Wesley) — Thu, 11 Jan 2001 02:00:00 +0900

The Champion - Alpha PAL6035

PAL6035 is a socket HSF from Japan's Alpha Company Ltd.. Alpha has been producing high quality heatsinks with their 'microforging' technology(hence the URL) that enables them to make create heatsinks of efficient shapes since 1989. PAL6035 is one of the top performing heatsinks they offer, second only to PEP66. Here are some key specs of PAL6035:

Specification
Dimensions(mm):	60 x 60 x 35
Mass (grams):	175
Cooling Fan:	Sanyo Denki 60mm
Fan Speed(rpm):	3800
Fan Power(cfm):	20.0
Thermal Resistance:	0.37 C/W

The specifications reveal that the heatsink is quite a competent model, and it has consistently proven to be well-performing throughout various tests performed by hardware sites such as HardOCP or Tom's Hardware. So we can say it is a good 'reference' high-performance HSF.

PAL6035's Packaging

Alpha PAL6035 comes completely unassembled, in part because you assemble the heatsink as you install it on the CPU. In the picture, you see the black-anodized heatsink with Alpha's unique copper-plated bottom. You also see the heatsink cover for effective airflow, as well as the 20cfm Sanyo Denki 60mm fan. This fan is standard part of the PAL6035MUC package that Alpha sells directly. If you get PAL6035 from other places, it may be replaced with different fans. The clip shown here is the old kind, and Alpha has updated the clip for better compatibility with AMD's SocketA CPUs. However, with a bit of bending, the old clip works with SocketA fine. To wrap up the packaging, there is a set of screws for attaching the fan onto the heatsink and Alpha brand thermal grease in a tube.

PAL6035 Installation

Installing Alpha is something of moderate difficulty, but not confusing. First you put the clip into the heatsink, then attach it onto the processor. Depending on how dexterous the person is, you can push the clip down with a finger and snap it into place, or a small flathead driver may be necessary to aide/guide the clip in. That's the hard part. Then you put on the cover and screw on the fan to finish installation to get it look like the picture above. Unlike the picture, you have to plug the fan connector in to get it work, of course.

Now let's take a look at the contender.
