摘要： A structure and method for entering data into an electronic device (110). A deterministic data input element (130) coupled to the electronic device (110) is operable to accept a user-selected data input. Modulation of a motion of a non-deterministic data input element (140) coupled to the electronic device (11) is operable to select a varying precision of data input choices. A feedback element (120) coupled to one or more of the deterministic data input element (130) and the non-deterministic data input element (140) presents the data input choices to the user. The user enters data into electronic device (110) using one of the deterministic input element (130) and the non-deterministic input element (140) and the feedback element (120) displays a sequence of data choices to the user. The user then navigates a tree of possible data completions in order to select a particular data completion to be entered into the electronic device (110).

The voice recognition system is utilized for receiving caller initiated messages, and the transmitter is used for transmitting messages to a plurality of SCRs (selective call radios) (122) of the radio communication system.

摘要： A communication system includes a transmitter for transmitting messages to a plurality of receiving devices of the communication system, and a processing system. The processing system is adapted to convert a caller's voice message to a sequence of phonemes whereby the caller's voice message is intended for a receiving device. To accomplish the conversion, steps of Fourier transform, spectral subdivision, envelope filtering autocorrelation function determination of each subdivision, and voiceness determination for each subdivision are performed. The processing system is further adapted to generate a sequence of phoneme indexes and voice features corresponding to the sequence of phonemes, and to cause the transmitter to transmit the sequence of phoneme indexes to the receiving device for generating a voice signal representative of the caller's voice message. The voice features can include spectral features, average energy, duration, and pitch to improve the quality of the voice signal. The receiving device can be a selective call radio.

摘要： A radio communication system includes a voice recognition system (221) for converting (400) a caller's voice message to a textual speech message. The textual speech message is then transmitted to an intended selective call radio (122). To perform these functions, the radio communication system includes a caller interface circuit (218), a transmitter (116), and a processor (222). To perform voice-to-text conversion, the processor is adapted to cause the caller interface circuit to sample a voice signal generated by the caller during a plurality of frame intervals, and to apply a Fourier transform thereto, thereby generating spectral data. The spectral data is subdivided into a plurality of bands. The spectral envelope of the spectral data is then filtered out to generate filtered spectral data. A Fourier transform is applied thereto to generate an autocorrelation function for each band. From the autocorrelation function of each band, a magnitude is determined, which is representative of the degree of voiceness of each band. The degree of voiceness for each band is then applied to a corresponding plurality of phoneme models, which are used to derive a textual equivalent of speech from the voice signal. The textual equivalent of speech is then transmitted to the selective call radio by way of the transmitter.

摘要： A multiple camera imaging system, comprising: a first camera image sensor configured to obtain a first image of a scene from a first vantage perspective point; a second camera image sensor configured to obtain a second image of the scene from a second vantage perspective point; and an image signal processor (ISP), configured to process the first image and the second image by performing the following steps: producing a first roughly-aligned image from the first image, and a second roughly-aligned image from the second image; using the first and second roughly-aligned images to produce a disparity image; identifying a feature point within the first roughly-aligned image; utilizing the disparity image to create a search zone within the second roughly-aligned image; and identifying a group of candidate feature points within the search zone; identifying within the search zone a best-matched candidate feature point that best matches the feature point within the first roughly-aligned image to form a best-matched feature point pair; and using information from the best-matched feature point pair to further align the first and second roughly-aligned images.
