Abstract: A light activated optical parking guide includes a container, a dark tunnel, a light detector, an electrical level detector, a power switch and one or more laser pointers. The dark tunnel couples light from the garage door opener bulb to the light detector and limits ambient light. The light detector generates an electrical level which triggers a threshold when the garage door light bulb goes on. The threshold switch supplies power to one or more laser pointers, which point to a target on the vehicle driver's dashboard when vehicle arrives at the desired parking position, giving both forward-back and left-right alignment.

Abstract: A cost effective continuously adaptive digital video system and method for compressing color video data for moving images. The method describes capturing an analog video frame and digitizing the image into a preferred source input format for compression using a combination of unique lossy and lossless digital compression techniques including subband coding, wavelet transforms, motion detection, run length coding and variable length coding. The system includes encoder and decoder (CODEC) sections for compression and decompression of visual images to provide high compression with good to excellent video quality. The compressed video data provides a base video layer and additional layers of video data that are multiplexed with compressed digital audio to provide a data stream that can be packetized for distribution over inter or intranets, including wireless networks over local or wide areas.
