Having trouble gliding your fingers on touchscreens?

Having trouble gliding on your smartphone or iPad? A stylus pen is highly recommended for replacement of your fingers. A Stylus pen is a small pen-shaped instrument that is used to input commands to a computer screen, mobile device or graphics tablet. With touchscreen devices, you can place a stylus pen on the surface of the screen to draw or make selections by tapping the stylus on the screen.

 

Stylus pen is the primary input device for personal digital assistant. It is used on the Nintendo DS, Nintendo 3DS game consoles and the Wii U’s Wii U GamePad. Some smartphones require a stylus for accurate input. However, devices featuring multi-touch finger-input are becoming more popular than stylus-driven devices in the smartphone market. Capacitive stylus, different from standard stylus, can be used for these finger-touch devices, iPhone, etc.).

Without the Stabilizer Bar, the Car Would Be Nothing!

A Stabilizer bar is the part of a car’s suspension system which precludes the body of the car from rolling in a sharp and quick turn.  It means that the bar will help the car reducing the body roll of a vehicle over rough or broken pavement and fast cornering and keep the body flatting by transferring force from one side to the other side.

A stabilizer bar, also called “sway bar” or “anti-roll bar”, is made of torsion spring and formed out of a wide and U-shaped steel bar that connects the body at two points with the left and right side of the suspension.  In general, when both left and right wheels move together, the bar will rotate about its mounting points.  Relatively, when the wheels move to each other, the bar will be subjected to torsion and be forced to twist.

Through the innovation of technology, many high-tech manufacturers produce high-quality automobile stabilizer bar because this bar can be used in various kinds of car, such as auto racing or Super GT.  We can know that the sway bar is the significant material in the vehicles or the related machineries.

Definition of Machine Vision

Machine vision (MV) is a branch of engineering that uses computer vision in the context of manufacturing. While the scope of MV is broad and a comprehensive definition is difficult to distil, a "generally accepted definition of machine vision is '... the analysis of images to extract data for controlling a process or activity.' " Put another way, MV processes are targeted at "recognizing the actual objects in an image and assigning properties to those objects--understanding what they mean."

The main categories into which MV applications fall are quality assurance, sorting, material handling, robot guidance, and calibration.

As recently as 2006, one industry consultant has reported MV to represent a $1.5 billion market in North America. Though, another technology observer asserts that "machine vision is not an industry per se" but rather "the integration of technologies and products that provide services or applications that benefit true industries such as automotive or consumer goods manufacturing, agriculture, and defense."

ASRock's High-End Vision 3D HTPC Reviewed

ASRock started introducing small form factor (SFF) HTPCs last year. Their first play in the market was an ION based Atom nettop, and it could best be termed as an entry-level machine. While being a good fit as a secondary HTPC, it failed to satisfy the power users. Absence of HD audio bitstreaming and lack of processing power for many common HTPC tasks were important reasons. In an effort towards alleviating these concerns, ASRock introduced a mainstream SFF HTPC a couple of months back, namely, the Core 100. With a Core i3 mobile processor combined with the integrated Arrandale IGP, things started to look good for the SFF HTPC space. We had unreserved praise for the Core 100, but the Intel HD Graphics did have some shortcomings for the purists in terms of support for the latest Blu-Ray features and potential for gaming.

The Vision 3D was announced at the 2010 Computex show in the first week of June. The aim of this product was to make a foray into the high end HTPC space by offering cutting edge technology such as 3D movie playback and 3D gaming to the consumers. The initial plan was to use a GeForce 3xxM or 4xxM as the GPU inside the Vision 3D. Had ASRock rushed the release of the HTPC and gone with the 3xxM card, the unit would have been DOA due to the lack of HD audio bitstreaming. Instead of rushing to the market with a half-baked product, ASRock wisely decided to wait for nVidia to get its HTPC game straight. What we have on our hands now is a HTPC very similar to the Core 100, with the additional power of the GeForce 425M replacing the Intel IGP for the graphics duties.

What makes the Vision 3D a high end unit? For starters, it is the first pre-built HTPC to support HD audio passthrough as well as Blu-Ray 3D playback with HDMI 1.4a support. It is evident that this HTPC will remain future proof for quite some time to come. 3D technology is yet to become mainstream, with displays still being priced out of reach of the average consumer. ATI and Intel are yet to bring HDMI 1.4a support in their GPUs. These facts combine to make ASRock a pioneer of sorts in the SFF HTPC field. The closest competition to the ASRock Vision 3D comes in the form of the Dell Zino HD. However, even the highest end configuration of the Zino HD doesn't support 3D Blu-Ray playback. Based plainly on the specs, it looks like all the bases are covered for the consumer on the leading edge who doesn't want to mess around with building his own HTPC. Does the Vision 3D deliver on its promise? That is what we are set to find out in the course of this review.

DAQ hardware

DAQ hardware is what usually interfaces between the signal and a PC. It could be in the form of modules that can be connected to the computer's ports or cards connected to slots in the mother board. Usually the space on the back of a PCI card is too small for all the connections needed, so an external breakout box is required. The cable between this box and the PC can be expensive due to the many wires, and the required shielding.

DAQ cards often contain multiple components (multiplexer, ADC, DAC, TTL-IO, high speed timers, RAM). These are accessible via a bus by a microcontroller, which can run small programs. A controller is more flexible than a hard wired logic, yet cheaper than a CPU so that it is permissible to block it with simple polling loops. For example: Waiting for a trigger, starting the ADC, looking up the time, waiting for the ADC to finish, move value to RAM, switch multiplexer, get TTL input, let DAC proceed with voltage ramp. Many times reconfigurable logic is used to achieve high speed for specific tasks and digital signal processors are used after the data has been acquired to obtain some results. The fixed connection with the PC allows for comfortable compilation and debugging. Using an external housing a modular design with slots in a bus can grow with the needs of the user.

Not all DAQ hardware has to run permanently connected to a PC, for example intelligent stand-alone loggers and oscilloscopes, which can be operated from a PC, yet they can operate completely independent of the PC.

 

USB 2.0 Cable

It is not obvious whether the connector should be face up or face down, and thus it is often necessary to try the insertion both ways. The side of the connector on a USB 2.0 cable or other product with the "USB Icon" (trident logo) should be "visible" to the user during the mating process. Some manufacturers do not, however, make the trident logo on USB 2.0 cable and related products easily visible or detectable by touch. Additionally, some computers such as the Mac Mini, have the ports vertically, in many Japanese computers and other devices, the trident logo on the cable or other USB device being inserted must be facing down, while in many American computers and devices the logo must be facing up. However, this is not always the case, such as with some Dell (an American company) computers.

Officially, the USB 2.0 specification states that the required USB Icon is to be "embossed" ("engraved" on the accompanying diagram) on the "topside" of the USB plug, which "provides easy user recognition and facilitates alignment during the mating process."[15] The specification also shows that the "recommended" (optional) "Manufacturer's logo" ("engraved" on the diagram but not specified in the text) is on the opposite side of the USB Icon. The specification further states "The USB Icon is also located adjacent to each receptacle. Receptacles should be oriented to allow the Icon on the plug to be visible during the mating process." However, the specification does not consider the height of the device compared to the eye level height of the user, so the side of the cable that is "visible" when mated to a computer on a desk can depend on whether the user is standing or kneeling. Although published eight years later, the USB 3.0 specification has similar wording, stating only "USB 3.0 receptacles should be orientated to allow the Icon on the plug to be visible during the mating process.

Why buy USB 3.0 Cable

USB 3.0 also known as SuperSpeed USB is poised to be the next protocol change that you should be paying attention to. As early as 2007 a new USB standard known as USB 3.0 was introduced and the specs have began to be integrated into modern computing hardware. So why is it a trend to buy USB 3.0 Cable? It’s very easy to comprehend. Superspeed USB is fully backwards compatible but also opens up a whole new world of speed in data transfer abilities.

USB 2.0 is supposed to work at up to 480mbps but is more likely to run around a 320mbps transfer rate to compare USB 3.0 or Superspeed USB can run a transfer rate of 4.8Gbps which is an incredible boost in capabilities.

This increased speed can be very useful for transfer of large files between high capacity external drives especially if you often read/write directly to your external - the speed and ease of file transfer between your PC and camera or media phone should be impressive also.

It’s a time of USB 3.0. Go buy an USB 3.0 Cable to experience the speed.

About Digital Audio Cables

The cables and connectors used to interface various components in sound systems play a key role in enhancing your audio experience.

Today's audio devices no longer use analog signals to create sound. They use digital signals derived from data, namely, 0's and 1's.

The term ‘analog’ is used for phonographs and audio cassettes. Digital media includes CD's, MP3's and DVD’s, in which audio signals are processed by a chip to create superior sound. Digital audio cable is manufactured with the aim to preserve and transmit the digital signals, maintaining the highest possible quality. They come in two distinct flavors; coaxial digital cables and optical digital cables.

Coaxial digital cables are the most common type of connection cable used for digital audio. They look similar to the RCA cables that many people use and are familiar with. The only difference is that it carries digital signals instead of analog signals. These cables look very similar to standard analog RCA cables. They are thicker than RCA cables and are shielded just like regular cable TV coaxial cables. The interference from outside signals is minimized with greater shielding.

Coaxial digital cables transmit digital signals in pulses of electricity. They consist of copper wires shielded from interference with the help of surrounding aluminum wraps. The wires are housed in a strong outer case. Coaxial digital cables used for audio applications have an impedance of 75 ohm, which means they can handle considerable energy. Also, they have a larger bandwidth than a normal RCA cable. For an affordable digital audio cable that delivers premium sound, coaxial digital cables are an extremely attractive choice.

Four Types of HDMI Connector

There are four HDMI connector types. Type A and type B are defined in the HDMI 1.0 specification, type C is defined in the HDMI 1.3 specification, and type D is defined in the HDMI 1.4 specification.

Type A

Nineteen pins, with bandwidth to support all SDTV, EDTV, and HDTV modes. The plug (male) connector outside dimensions is 13.9 mm × 4.45 mm and the receptacle (female) connector inside dimensions is 14 mm × 4.55 mm. Type A is electrically compatible with single-link DVI-D.

Type B

This connector (21.2 mm × 4.45 mm) has 29 pins and can carry double the video bandwidth of type A, for use with very high-resolution future displays such as WQUXGA (3840×2400) Type B is electrically compatible with dual-link DVI-D, but has not yet been used in any products.

Type C

A Mini connector defined in the HDMI 1.3 specification, it is intended for portable devices. It is smaller than the type A plug connector (10.42 mm × 2.42 mm) but has the same 19-pin configuration. The differences are that all positive signals of the differential pairs are swapped with their corresponding shield, the DDC/CEC Ground is assigned to pin 13 instead of pin 17, the CEC is assigned to pin 14 instead of pin 13, and the reserved pin is 17 instead of pin 14. The type C Mini connector can be connected to a type A connector using a type A-to-type C cable.

Type D

A Micro connector defined in the HDMI 1.4 specification keeps the standard 19 pins of types A and C but shrinks the connector size to something resembling a micro-USB connector. The type D connector is 2.8 mm × 6.4 mm, whereas the type C connector is 2.42 mm × 10.42 mm; for comparison, a micro-USB connector is 2.94 mm × 7.8 mm and usb a is 11.5 mm × 4.5 mm.

What is a 3G Antenna?

A 3G antenna enhances local internet signal strength and permits the use of devices on a local wireless network. 3G refers to the third generation wireless technology that provides high speed access to mobile telephone and data transfer systems. Installation of a 3G antenna should improve data reception, reduce signal noise and increase transfer rates. 3G antennas are used in some cell phones and handsets to allow for quicker access to the Internet, including sending e-mails, taking part in video conferences and streaming videos. Other uses include antennas for laptops and computers to increase the connection strength when using the Internet.

International Mobile Communications 2000 (IMT-2000) started using the pattern of "G" in the 1990’s. IMT-2000 began these designations with 2G technology, which was recognized as the technology responsible for the mobile phone network that is in use today. IMT-2000 then progressed to 2.5G, which provided a faster transfer of data, and now the 3G technology allows for the simultaneous use of voice telephone and data transfers. Compared to 2G and 2.5G, 3G is faster and must maintain a data transfer rate of 200 kilobytes (KB) per second to maintain the 3G rating.

There are three common types of 3G antenna that are available. The clip antenna is designed to clip directly onto the screen of the user’s laptop and is best suited for users who travel and use their computers in areas with generally adequate coverage. The High Gain antenna is used for areas with low signal to boost the signal so that a faster and better connection is provided to the user. The Outdoor Antenna is meant for those who have a poor signal or live on the edge of a signal area, usually remote areas, and it boosts the signal to allow the user to be able to connect to the Internet.

Some 3G antennas are omni-directional. This means that they can pick up signals from any direction and do not require to be aimed directly at local network tower. Omni antennas are useful for users who want a mobile antenna to boost an existing steady, but weak, signal.

A 3G antenna can also be directional, which requires precise aiming of the antenna toward the tower to get the maximum benefit. By finding the nearest tower, or directing the 3G antenna toward the strongest signal, the antenna can provide a boost to the signal. Some antenna suppliers boast that if a user installs their antenna, they will be provided with a signal where there was none before.
