摘要： A modulated backscatter radio frequency identification device includes a diode detector configured to selectively modulate a reply signal onto an incoming continuous wave; communications circuitry configured to provide a modulation control signal to the diode detector, the diode detector being configured to modulate the reply signal in response to be modulation control signal; and circuitry configured to increase impedance change at the diode detector which would otherwise not occur because the diode detector rectifies the incoming continuous wave while modulating the reply signal, whereby reducing the rectified signal increases modulation depth by removing the reverse bias effects on impedance changes. Methods of improving depth of modulation in a modulated backscatter radio frequency identification device are also provided.

摘要： A system for coupling a warning light to a rear of a vehicle. The system includes a coupling bar for connecting the unit to a conventional tow bar deployed on the rear of the vehicle. A beacon mount is pivotally connected to the coupling bar so that it may be pivoted away from the rear of the vehicle without removing the unit from the tow bar. A warning beacon is affixed to the top of the beacon mount such that when the system is deployed, the beacon is positioned at or above the height of the vehicle. A supplemental beacon guard may be deployed adjacent to the beacon so as to prevent direct viewing of the beacon by the vehicle driver. The coupling bar comes in two designs. The first includes a pair of extensions that terminate in rear-facing lights designed to enhance visibility behind the vehicle. Corner markers may also be employed on the ends of the extensions to provide the driver with a visual identifier of the rear corners of the vehicle. The other embodiment of the coupling bar includes on the beacon mount a pair of rear-facing lights. The system may alternatively be used deployed in a roadway as a warning light system for oncoming traffic.

摘要： A manufacturing method enables the manufacture of a remotely controlled network device management system. The manufacturing method includes the steps of obtaining a software program, obtaining a downloadable unit (e.g. an applet) configured to communicate with the software program, compiling the software program into a binary file, embedding the downloadable unit into the binary file, and loading the binary file with the embedded downloadable unit onto the network device. A management method enables a remote client to manage the network device. The management method includes the steps of receiving from a remote client a request to manage a software program which has a binary file with an embedded downloadable unit, locating the downloadable unit embedded in the binary file, extracting the downloadable unit from the binary file, and forwarding the downloadable unit to the remote client.
