Abstract: A system for limiting the speed of a vehicle includes a first module that generates a first torque signal based on a vehicle speed, a second module that generates a second torque signal based on a difference between a predetermined vehicle speed limit and the vehicle speed, and a third module that generates an output torque signal based on the first and second torque signals. The output torque signal is adapted to control the output torque of a motor.

Abstract: An alert transceiver in commuter vehicles in a line-of-site warning area receive line of sight (LOS) alert signals from another vehicle, such as an emergency vehicle. Upon detecting the LOS alert signal, the alert transceiver can relay the alert signals to other alert transceivers in commuter vehicles within a warning zone that are outside of LOS zone, thereby creating mobile tracking network (MTN). The alert signals can include any relevant information, such as information regarding a hazard that includes the type of hazard (emergency vehicle, fire, ambulance, etc.), the time stamped location, direction of travel, speed and planned route for the emergency vehicle; and/or the coordinates of warning zone as determined by alert transceivers.

Abstract: An apparatus and a method for using a serial data line to turn on an electrical device are disclosed. Energy is extracted from a data signal on an asynchronous serial data line using a charge pump. The extracted energy is used by a power supply switching circuit to turn power on. Once turned on, power is kept on by a keepalive circuit. A shutdown signal causes the power to be turned off.

Abstract: The fungus, Rhizopus nigricans, can be used as an insecticide for use in killing ants in the order Hymenoptera. When this fungus is brought into or put into an ant hive, it kills the ants within a few days.

Abstract: A structure for reflecting visible light or near visible light, wherein the structure is formed of a low dielectric constant material having an external surface comprising an electrically conductive layer of material which has an array of slots therein so as to be substantially transparent to microwave radiation of a predetermined wavelength which will impinge upon the structure during use, while being reflective to light.

Abstract: A conductive gasket for use in electro magnetic interference protection of electrical apparatus comprises an elastomeric material in which high aspect ratio conductive fibres are embedded to provide the conductive paths across the gasket. Preferably the fibres are carbon fibres.

Abstract: A metal sleeve having a substantially cylindrical outer surface and having first and second inner surfaces tapering outwardly longitudinally from at least adjacent the center thereof is formed to provide equal angles with abutting ends of two hollow cylindrical members such as pipe; the center inner surface of the sleeve is formed to contact abutting ends of the two hollow cylindrical members at least adjacent the ends thereof. The sleeve has a high explosive mass placed circumferentially thereon and is formed of a circumferential body having a greater thickness at least adjacent the center of the mass than at its ends such that on detonation maximum explosive impact is exerted inwardly toward said sleeve to weld the abutting ends together.
