Abstract: A system includes a camera, a weigh-in-motion scale, and a processor. The camera is configured to capture one or more images of a vehicle as the vehicle goes over the weigh-in-motion scale. The weigh-in-motion scale is configured to generate one or more weight measurements of the vehicle as the vehicle goes over the weigh-in-motion scale. The processor is operatively coupled to the camera and the weigh-in-motion scale. The processor is configured to determine an acceleration of at least a portion of the vehicle based at least in part on the one or more images of the vehicle. The processor is also configured to adjust at least one of the one or more weight measurements based on the acceleration.

Abstract: A wireless distribution secured cabling system includes faceplates, each of which contains an antenna or other radiating element and an active amplifier, which serves as a bi-directional repeater for the wireless communication system. The system further includes a patch panel or distribution module which connects multiple cables, which may be either twisted pair or coaxial, to amplifier, acting as a power divider and/or an impedance matching device. An antenna, which may be mounted either outside of a building structure or inside the building structure, provides communications between the structured cabling system and a service provider base station.

Abstract: A keyed modular connection system including a nonstandard wiring configuration, a plug wired in the preselected nonstandard wiring configuration and including exterior surfaces that define plug recesses, a jack wired in the preselected nonstandard wiring configuration and including interior surface that define jack recesses, plug protrusions extending from the external surfaces of the plug and configured to be received by the jack recesses when the plug is inserted into the jack, jack protrusions extending from the internal surfaces of the jack and configured to be received by the plug recesses when the plug is inserted into the jack, and when a plug not wired in the preselected nonstandard wiring configuration is attempted to be inserted into the jack, the jack protrusions prevent the attempted insertion, and when the plug is attempted to be inserted into a jack not wired in the preselected nonstandard wiring configuration, the plug protrusions prevent the attempted insertion.

Abstract: An apparatus and method for estimating the power spectral density of an unknown illuminant that does not require direct spectral measurements. The apparatus and method allows calibration of color images taken with commercially available digital cameras in arbitrary illumination. Besides an imaging system, a digital computer, a means for transferring image information from the imaging system to the digital computer, and software to carry out the method, the only additional equipment a photographer needs is a set of color standards.

Abstract: An emergency power circuit powers an induction motor which has at least first and second windings. The motor is normally operating at a normal speed determined by connection to commercial frequency power line, but which is subject to failure. During failure the emergency power circuit is used to supply emergency power from a DC storage battery. An inverter is supplied by the battery and has an output connectable to the motor. A control circuit for the inverter establishes a first frequency to run the motor at a running speed which is considerably less than the normal speed. Single, two-phase and three-phase systems are disclosed as well as a soft start system to start the motor at about one-fourth speed and run it at one-half speed. Preferably a high frequency oscillator is used with the frequency divided dozen to operate the motor at a speed below normal 60 Hz energization speed.

Abstract: A safety holster for a folding knife having a handle and a folding blade with the holster having a frame formed of side plates with an upper spacer and a lower pivotal blade sheath having an upwardly facing pocket for the tip of a folding blade with the pocket pivoting from a vertical upwardly facing position to a downwardly facing position to drawn the knife blade away from the knife handle to a use phase when the handle is drawn downwardly and permit the knife handle to be drawn upwardly without drawing the blade away from the handle.

Abstract: A battery charging circuit includes a silicon controlled rectifier full wave bridge that has its input connected across a conventional 60 hertz alternating current power line. The output of the bridge provides 120 hertz pulsating direct current to the battery being charged. The duration of each direct current charging pulse is determined by phase triggering of the silicon controlled rectifiers in the bridge. The silicon controlled rectifiers are triggered at a predetermined, identical firing angles by a conventional unijunction transistor relaxation oscillator which in turn is regulated by an output voltage and output current sensing circuit that established the noted firing angles so as to regulate, and limit at desirable upper valves, the charging voltage and current applied to the battery.

Abstract: A battery pack-containing solid state circuit, normally in a standby condition, automatically applies battery-generated power to a multi-power requirement load a predetermined time period subsequent to detection of a malfunction in the load's normal power source. In switching to its power-applying state, the circuit disconnects the load from its malfunctioning power source and energizes the load at a level consistent with the battery pack capabilities. The circuit includes a unique fold-back-characterized, overcurrent-protected inverter and a temperature-compensated battery charger. A low battery voltage sensor exhibiting hysteresis characteristics inhibits operation of the circuit when the battery voltage drops below a predetermined level indicative of a discharge condition, the low voltage sensor continuing to inhibit operation of the circuit until a battery voltage charging input regains a level in excess of the predetermined level at which the discharge battery initially inhibited circuit operation.
