Abstract: Systems and methods for configuring and using a Wi-Fi-based motion detection system are provided. Devices connected to a wireless local area network (WLAN) may be configured to provide channel state information regarding radio frequency signals transceived by the devices. The channel state information may be received and used, e.g., by a wireless routing device, to detect motion within an WLAN environment. Detected motion, or the lack thereof, may be considered a Wi-Fi-based motion detection event, and various home-automation and/or security actions may be defined (e.g., through a user interface) to be caused by a determination that a Wi-Fi-based motion detection event has occurred. Among other uses, motion detection information may also be made available to third-party systems (such as emergency services systems), which may permit active querying of Wi-Fi-based motion detection systems to enable first responders to find occupants more quickly in case of an emergency.

Abstract: A personal versatile recorder can be connected to, or integrated in, a cable television set-top terminal. The personal versatile recorder includes a central processing unit and a hard drive for mass data storage. Preferably, the personal versatile recorder has a tuner or tuners for receiving one or more transport streams from the cable system as well as analog or digital audiovisual programming. The data transport stream may encompass internet multimedia web content and associated applications to he utilized by the personal versatile recorder, Under instructions of the viewer or the agent application the central processing unit controls and facilitates various functions such as encoding, transcoding, decoding, caching, storing, playback and retrieval of any type of data or data file on the hard drive including compressed audiovisual programming content, streamed multimedia cached content, picture files, video files, audio files, HTML files, etc. for a variety of applications as described.
