Although some companies are trying to make AR and VR more immersive through tactile feedback, a startup company decided to focus on the heat experience. TEGway is a branch of the Korea Advanced Institute of Science and Technology. It invented a light and flexible thermoelectric device called TED. The product can be quickly regulated between 4-40 degrees Celsius, producing different hot and cold areas on the same surface to simulate the pain on the skin. Now the product has finally launched the consumer brand ThermoReal. TEGway hopes that hardware manufacturers can integrate the solution, such as remote control sticks, gloves, tactile coats, chairs, etc., to bring the immersive experience to a new level.
The TED achieves cold and heat changes by utilizing the current passing through the gas-thermoelectric semiconductor array. This can generate heat flow between the top and bottom ends for heating and cooling. But in fact its reverse process is easier to understand: the temperature difference on the semiconductor can generate current. In this case the TED is like a generator and can be used to collect waste heat.
In order to optimize non-surface heat capture, TEGway found a way to develop flexible TED. Compared with ceramic materials, this not only can better absorb energy, the company also found a new application - it uses thermal feedback to increase the realism of the game, so the commercial product is called ThermoReal. Inside it are two hot and cold lines that are parallel to each other. When electricity is turned on, there is a meeting between cold and heat, which causes pain. ThermoReal is also known as a self-abusing device.
TEGway showed related applications at the HTC Vive X Project DEMO. This DEMO can demonstrate the experience in hot and cold environments. When simulating a cold environment, players will dive into the icy water. The deeper the depth, the colder the water. At this time players will feel cold in their hands. Instead, there is a hot simulation part of the game. In order to show its rapid thermal response, the rod's temperature is also constantly fluctuating.
Overall, ThermoReal's reality is excellent. Now TEGway is convincing other hardware manufacturers to integrate this functionality into the hardware. On the software side, companies will provide software authorisations to content creators.
A Small Computer System Interface (SCSI) connector, also pounced as [scuzzy" connector, is used for physically connecting and transferring data between computers and peripheral devices.
SCSI is the small computer system interface, which is an independent processor standard used for the system level interface between computer and intelligent devices (hard disk, floppy, optical drive, printer, scanner, etc.). It is an intelligent universal interface standard, which has the function of communicating with various types of peripherals. SCSI uses the standard software interface of ASPI (SCSI programming interface) to make the driver communicate with the SCSI adapter installed inside the computer. SCSI interface is widely used in high-speed data transmission technology on minicomputers. SCSI interface has many advantages, such as wide application range, multitask, wide bandwidth, low CPU utilization, and hot plug.
SCSI connectors type and interfaces
Centronics 50-pin connector: The Centronics 50-pin connector was once the most widely used SCSI connector. An external connector only, the Centronics is a SCSI-1 connector that looks the same as the Centronics cable that attaches to a parallel port printer. The Centronics 50-pin cable comes in male and female styles, and gender changers and cable converters are commonly available. Although used on older SCSI devices and external drive enclosures, this interface is no longer heavily used, due to its slow speed and short cable lengths.
High-density 50-pin connector: The high-density 50-pin connector is used on scanners and Jaz drives. It is one of the more common SCSI connectors and is usually used to connect SCSI-2 devices. Both ends of the cable are usually 50-pin male, while the sockets on the host adapter and external devices are 50-pin female.
DB 25-pin connector: The DB 25-pin or D Sub 25 is by far the most widely used connector. This connector is used for parallel and serial printers in addition to the many other devices available. Both ends of the cable are usually 25-pin male, while the sockets on the host adapter and external devices are 25-pin female. This cable is almost always an external connector.
Note: DB-25 SCSI CABLES are not compatible with and should not be used as serial or printer cables; serial cables and printer cables should not be used or attached to DB-25 SCSI adapters. You can short out the SCSI host adapter or the motherboard by using the wrong cable. Marking cables is the best way to avoid this.
IDC50 connector: The IDC50 is the most common internal SCSI connector. It is very similar to the standard IDE internal ribbon cable. The IDC50 SCSI cable is considerably wider then an IDE ribbon cable; in fact, it is usually the widest standard internal cable in use. This is a standard SCSI-2 10MBps internal SCSI cable. Many low-end cables have only two or three connectors, allowing for one or two devices to be attached to the cable. Seven-device cables are available, though they are often expensive and require a large case, as the cables may be four or five feet long.
High-density 68-pin connector: The high-density 68-pin connector is the SCSI connector of choice for SCSI-3 host adapters and peripherals. There is an internal ribbon cable version that looks very similar to the IDC50 connector. Many low-end cables have only two or three connectors, allowing for one or two devices to be attached to the cable. Seven-device cables are available, though they are often very expensive and require a large case, as the cables may be three or more feet long. Both ends of the external cable are usually 68-pin male, while the sockets on the host adapter and external devices are 68-pin female.
SCA 80-pin Micro-Centronics connector: SCA stands for Single Connector Attachment, a type of disk drive connector that includes connection pins for the power cables as well as the data wires. A SCA connector uses an 80-pin plug and socket to connect peripherals. This connector combines power, data channel, and ID configuration for fast installation and removal. SCA connectors are typically found only on high-end SCSI hard disks. The SCA interface was designed to provide a standard connection for systems using drives that can be hot-swapped. SCA makes swapping SCSI hard drives much easier than with traditional SCSI cables, plugs, and sockets. An adapter enables SCA drives to fit into standard SCSI enclosures.
SCSI SFF 8482: Also called "4x internal" by some vendors. This is a connector with the same form factor as SATA with the addition of a "bump" to key it specifically for SAS. (SATA drives can be plugged into SAS controllers, but SAS drives will not function with a SATA controller; hence, the necessity for the key bump on the connector.) As the name says, it's meant to be used internally, i.e., inside the computer case.
SCSI SFF 8484: Also called "32-pin" or "MultiLane". This is a high density connector usually intended to plug into the motherboard, controller, or backplane itself. Cables with this connector on one end usually have four individual SFF 8482 connectors on the other.
Serial Attached SCSI SFF 8470: Also called "4x external" by some vendors. This is simply a version of the SFF 8484 that's meant to be used with external (i.e., not located within the case) drives.
