DapTechnology's AS5643 interface card "FireTrac4x24bT" adopted in the F-35 project.

DapTechnology's AS5643 interface card adopted for the F-35 project.

There is a growing demand for more streamlined hardware systems for processing AS5643 data streams used for defense purposes. In particular, advanced error insertion capabilities, which cannot be achieved with commercial link layer implementations, are required for simulation purposes. FireTrac is designed to natively support AS5643 (not just as an add-on protocol). In addition to standard IEEE1394 functionality, FireTrac is designed to provide hardware-level support for SAE AS5643, particularly alleviating the burden on the host processor for tasks such as packet encapsulation, data extraction, and receive/transmit STOF offsets. Importantly, FireTrac is highly accurate as it fully processes AS5643 transmission timing in hardware. Support for this protocol is built into the hardware, rather than relying solely on a software layer as is commonly provided by other solutions that depend on COTS OHCI chipsets. ■ Technical documentation in Japanese for AS5643 is available.

• Expansion Boards

Analyzer package for the AS5643 avionics data bus adopted in the F-35 project.

The AS5643 I/F board comes in USB, LAN, and PCI/cPCI types. The AS5643 supports speeds of 100/200/400/800 bps. The bus analysis analyzer software FireSpy Mil1394 provides functions for Monitor, Recorder, Commander, Generator, Filter/Trigger, and Scriptor. ■ Japanese technical documentation for the AS5643 is available. If you would like to see it, please contact sales@nacelle.co.jp. Alternatively, it can also be downloaded from the catalog page.

The MIL1394 repeater is a solution for cable extension.

MIL1394, like the commercial IEEE1394 FireWire, has limitations on the length of the connection cable. Therefore, to extend a 1394 connection, it is necessary to use thicker wires or add signal repeaters. DapTechnology has developed a wide variety of repeater models, offering about 25 different configurations, including simple pass-through, multi-pass-through, fiber optic conversion, and EMI-enhanced solutions. Various cable harnesses are also available, using the proven GORE FireWire cables. ■ Technical documentation in Japanese for AS5643 is available.

"Electronic contracts for national and local governments are also available with 'paperlogic Electronic Contracts'" In December of last year (2023), we inquired about our service 'paperlogic Electronic Contracts' regarding the 'Law and Orders Related to Regulations on New Business Activities' utilizing the Digital Agency's gray zone resolution system. As a result, we received a response from the Digital Agency stating that 'paperlogic Electronic Contracts' can be used as an electronic record in place of paper contracts for national and local government contracts. "'paperlogic' is endorsed by the Digital Agency" In this inquiry, we received confirmation that 'paperlogic Electronic Contracts' can be utilized as an electronic record in place of paper contracts for national and local government contracts. From now on, you can confidently use 'paperlogic Electronic Contracts' not only for contracts between private companies but also for all types of contracts in local government practices, including administrative contracts and discretionary contracts. For business document digital transformation and electronic contract services, feel free to consult with paperlogic.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without affecting the base material with heat. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

Do you have any concerns or requests regarding wired bed exit sensors? × Tangling and tripping of wired cables × Cable disconnection or damage × Worry about forgetting to turn on the switch after temporarily stopping the sensor. × Want to be notified of bed exit even from a location away from the nurse call outlet. Such concerns can be resolved simply by connecting to a wireless set linked to the nurse call system! Our nurse call linked wireless set allows you to connect bed exit sensors like "Ugo-kun," "Foldable Thin Matta-kun," "Ayumi-chan," and "Just Place Pole-kun" to transmitters and receivers, reducing wiring around the bed, alleviating concerns about tripping and falling due to cables, and contributing to a tidier work environment. Furthermore, it enables the use of bed exit sensors even from locations away from the nurse call outlet, allowing for more flexible equipment placement.
