Rackmount Computer

The Trenton TMS4703 4U rackmount MIL-STD military computer from Trenton Systems (Gainesville, GA) is designed for mounting in a 19" component rack or a transit case. The TMS4703 has flexible MIL-DTL-38999 and MIL-STD-1553 rear I/O connector configurations designed for customer-defined applications. The sealed connectors, plus front- and rear-panel air filters, enable TMS4703 certification to various MIL-STD-810G and MIL-STD-461F standards and test methods. A rugged, lightweight aluminum chassis is used in the TMS4703, and a corrosion-resistant coating is applied to the chassis and fastening hardware.

Laser Encoders

HS10/HS20 laser encoders from Renishaw (Hoffman Estates, IL) allow Flow International Corporation’s Composite Machining Center (CMC) to machine 40-meter-long composite parts. With the precision of a laser interferometer, the encoder and its RCU10 real-time compensation unit deliver part-permillion positioning accuracy on the CMC’s X-axis.

Power Amplifiers

The Airborne Pulse HPA from Empower RF Systems (Inglewood, CA) features UHF and LBand pulse amplifiers tied to a shared power supply and delivering 1 kW and 3 kW pulse power, respectively. Each amplifier is housed in a 3U chassis, and the shared power supply is housed in a 1U chassis. The technology replaces older products which totaled 16U in size. The UHF pulse amplifier is designed with LDMOS, and the L-Band pulse amplifier is designed with GaN.

Avionics Digital Panel Meter

Specifically designed to replace “needle” meters in military aircraft, the new APM model from OTEK Corp. (Tucson, AZ) conforms to military and commercial 1"-diameter standards, as well as a variety of Mil-Standards, including 461, 704, 130, 810, and 889. The APM accepts 4-20mA or VDC signals (others upon request), 0-5VRMS/VDC for intensity (dimming) control, and 5-48VDC power input. The 4-digit (9.9.9.9) display is standard or NVG3-compliant. For new applications (not yet military-approved), the APM can be loop powered, eliminating the need for external power supply and wiring. The < 100mW loop power adds a burden under 5 VDC max to the loop, and has an operating range of 3-36mADC.
