Abstract: Systems, methods, and computer-readable media are provided for redundantly storing and authenticating event related video data from one or more cameras using a video recording manager device. Additional copies of event related video data are persisted across various storage devices including any combination of internal camera storage, remote storage, and one or more storage mediums associated with the video recording manager device. The stored video data is augmented with authentication metadata to preserve the authenticity such that the video data is suitable as evidence.

Abstract: A small, portable, hand-held electronic personal organizer performs voice recognition on words spoken by a user to input data into the organizer and records voice messages from the user. The spoken words and the voice messages are input via a microphone. The voice messages are compressed before being converted into digital signals for storage. The stored digital voice messages are reconverted into analog signals and then expanded for reproduction using a speaker. The organizer is capable of a number of a different functions, including voice training, memo record, reminder, manual reminder, timer setting, message review, waiting message, calendar, phone group select, number retrieval, add phone number, security, and "no" logic. During such various functions, data is principally entered by voice and occasionally through use of a limited keypad, and voice recordings are made and played back as appropriate. A visual display provides feedback to the user.

Abstract: A circuit for use with or built into a telephone set, that detects and intercepts the telephone company's ring signal, supressing the telephone set's existing ringer, and substituting instead, a user selected audio segment. A choice of audio segments may be made from an internal memory device or as downloaded from a supplier of such audio segments by high-speed modem. A synthesized stereo signal is generated so that an incoming phone call is announced by a high quality, stereo audio signal of ones choice such as the sound of wind, water or trees, animal sounds, music, or other sounds. Usable audio segments may be obtained via a built-in microphone or downloaded at high speed through the use of a built-in modem over phone lines.
