B & K Precision Corp.
Yorba Linda, CA 92887
Jun 09, 2008 Measuring 4 x 1.8 x 9 in. and weighing less than 2.0 lb, Model 2640 features frequency range of 100 kHz to 2,000 MHz, noise floor of -110 dBm to detect weak signals, and basic spectrum analyzer functionality. It has 2 GHz frequency counter, phase-locked loop for precise frequency tuning, detachable antenna, and back-lit display. Meter supports RS-232C serial communication, detects wide band and narrow band FM, AM, and SSB signals, and scans and displays up to 160 channels.

Pre-Tilted Gyro-Sensor aids in-dash navigation systems.

Seiko Epson Corporation
Suwa, Nagano   Japan
Nov 15, 2007 Suited for dead reckoning (DR) method used in car navigation, 6.0 x 4.8 x 3.3 mm XV-8000LK employs crystal gyro-element design, QMEMS, and low-power analog circuits that lend to stability. Solution is assembled with a pre-tilt angle in package, affording flexibility in determining installation angle. Available with 10° or 20° tilt angle, Pb-free product has airtight structure, employs temperature compensation circuit, and is resistant to shock and vibration.

Banner Engineering Corp.
Minneapolis, MN 55441
Jan 16, 2004 Utilizing magnetoresistive-based passive sensing technology, M-GAGEŽ S18M detects 3-dimensional changes in Earth's magnetic field when presence of large metal objects such as car, truck, or railcar is introduced, causing sensor's output to switch. Unlike inductive loop technologies, self-contained sensor functions as receiver and has no external controller. Program commands can be entered through pushbutton on sensor or via portable programming box when sensor is inaccessible.
