A system 10 for monitoring the load on a load carrying vehicle comprises an electronic radio frequency (RF) identification system 22 comprising a reader 24 and a plurality of RF transponders 28.1 to 28.n. Each transponder is associated with a respective load item 36.1 to 36.n, and the items collectively constitute the load located in a load carrying region of the vehicle. The reader is operative in use to interrogate the transponders, to read response data received from the transponders and to g...

The present invention relates to a body temperature warning and alarming device comprising an emitter and a receiver. The emitter can be set at a displaying value or a warning and alarming value. A detected body temperature is emitted to the receiver to display a warning signal or to emit a warning signal, such that person wearing the receiver is informed, and a suitable or an appropriate treatment can be provided to the person wearing the emitter.

A reconnaissance sonde to be dropped and erected in an area for wirelessly transmitting data to a data processing apparatus. The sonde includes a housing having top and bottom portions; a parachute disposed at the top housing portion; a plurality of support legs peripherally mounted on the housing in a circumferential array and having a folded state and a deployed state; a drive for simultaneously moving the support legs from the folded state into the deployed state upon landing of the sonde; a ...

A passive ranging system for determining the slant range from a ground station to a drifting radiosonde. In one embodiment, the ground station receives meteorological data ranging and internal temperature signals from the radiosonde. The data signals are read out as ambient conditions of the atmosphere and the range signal is phase-compared to a reference signal at periodic intervals. Changes in frequency due to temperature fluctuations in the radiosonde components are factored into the phase-co...

A method for calibrating a pressure-sensing altitude sensor of an aircraft while the aircraft is in flight. The method includes the steps of obtaining a set of reference atmospheric pressures as a function of height above a base station by affixing a reference pressure sensor to a balloon. As the balloon is released into the atmosphere, the reference sensor continuously measures the atmospheric pressures and transmits the data back to the base station while a ground-based radar disposed adjacent...

A receiving device is provided. A pulse width is measured, it is selected whether a determination process is performed for a pulse width having the length of one bit in accordance with the measured value of the pulse width or a pulse width having the length of 1/2 bit, it is discriminated whether a current pulse edge is a pulse edge at the center of the bit or a pulse edge at the boundary between bits while considering the bit data right before the determined bit, and when it is determined that ...

An event alert system and method provide event detection modules that communicate detected events with a central command center. The central command center combines the detected events with related data to provide an intelligent response signal, and communicates the intelligent response signal to event responders. The event alert system also provides an event detection module having event sensors able to detect a variety of types of events.
