Abstract: Channel changing apparatus for automatically scanning or incrementing the channel on a radio, television or other receiver and pausing for a set period of time on each channel to allow a user to preview to content. A scan speed adjustment control allows the user to vary the length of the preview period. The channel changing apparatus may be provided on a remote control device or integral to the receiver.

Abstract: Two enclosure are secured together to provide a safe the size and shape of a box spring for supporting a mattress. Wheels and handles are provided for transport. Fasteners for the enclosure, wheels, and handles are accessible only from the interior of the enclosures to inhibit unauthorized movement of the safe.

Abstract: A video image of a space is monitored and compared to a reference image. Correlation of the images indicates presence of unwanted persons or objects or the occurrence of unwanted events. When programmed comparison criteria are met, an alarm is activated, the space is displayed on a monitor, and the image is stored in memory. Reference images are stored during dedicated or ongoing learn modes.

Abstract: Conventional control modules, such as vehicle control modules, VCM, powertrain control modules, PCM, or engine control modules, ECM, provided with diagnostic and/or emulation ports, or simply with portions of the wiring harnesses which are devoted to diagnostic or emulation functions, are retrofitted with an adapter module which allows the originally manufactured control module to be reconfigured to operate in a dramatically different protocol without any system redesign. The memory within the originally manufactured control module can be disabled, bypassed or rewritten to store a new program contained in one of a plurality of programs in an adapter memory or contained in one of a plurality of memories in the adapter module. One application includes retrofitting conventionally manufactured gasoline or diesel vehicles to run on alternative fuel, such as propane, compressed natural gas or liquefied natural gas and the like.

Abstract: The ability of an automotive computer for controlling an engine is enhanced by allowing the automotive computer to be controlled by an arbitrarily selected one of a plurality of engine control programs according to arbitrary driver discretion. The bus connecting the computer and memory of a conventional automotive computer is connected to a computer controlled operator interactive control module and an expanded memory. The operator interactive control module allows a human operator to select one of a plurality of memories for coupling to the automotive computer to control engine performance. User on-site customization of the engine control program is permitted by allowing direct downloading of an engine control program into the automotive computer through the operator interactive control.
