Abstract: Modern portable electronic devices are commercially available with ever increasing memory capable of storing tens of thousands of song, hundreds of thousands of images, and hundreds of hours of video. The traditional means of selecting and accessing an item within such devices is with a limited number of keys and requires the user to progressively work through a series of lists, some of which may be very large. Provided is a method for speech recognition that allows users to efficiently select their preferred tune, video, or other information using speech rather than cumbersome scrolling through large lists of available material. Users are able to enter search and command terms verbally to these electronic devices and users who cannot remember the correct name of the audio-visual content are supported by searches based on lyrics, tempo, riff, chorus, and so forth. Further, pseudonyms may be associated with audio-visual content by the user to ease recollection.

Abstract: An automatic weapon safety system where power consumption is reduced and safety is increased is disclosed. The system includes a movement detector operatively associated with the handgrip of a weapon for detecting the presence of a hand on the handgrip. The system also has a transceiver operatively associated with the movement detector for sending a coded signal when the weapon has been gripped. The coded signal is received by at least one remote token which receives the coded signal and transmits a coded acknowledgement signal upon receipt of the coded signal. A system is provided for enabling and disabling the weapon, operatively connected to the transceiver for allowing operation of the weapon when the coded acknowledgement signal has been received. The system may include two tokens, which are worn by the authorized user.

Abstract: The device according to the invention provides a non-contacting temperature sensing device incorporating micro-bolometric detectors as the suitable infrared sensors for automotive applications. A first and second infrared sensors each include an active infrared sensing element and a temperature drift compensating element. A current bias is applied to the active infrared sensing element as well as to the temperature drift compensating element, which is identical in structure with the active infrared sensing element, and the voltage outputs of these two elements pass through a differential amplifier. The fluctuation in the substrate temperature or the ambient temperature affects the active sensing element and the compensating element in the same way, thus it is cancelled out. Instead of using one spectral band of the infrared radiation, as in the prior art, two spectral bands are used resulting in a first and second signal generated by the first and second infrared sensors.

Abstract: An automatic firearm safety system where power consumption is reduced and safety is increased is disclosed. The system includes a movement detector operatively associated with a trigger of a firearm for detecting movement of the trigger. The system also has a transceiver operatively associated with the movement detector for sending a coded signal when movement of the trigger has been detected. The coded signal is received by at least one remote token which receives the coded signal and transmits a coded acknowledgement signal upon receipt of the coded signal. A solenoid is also provided for locking and unlocking the trigger, operatively associated with the transceiver for allowing operation of the trigger and thereby the firing of the firearm when the coded acknowledgement signal has been received by the transceiver. The system may include two tokens, both of which are worn by the authorized user.
