  • Patent number: 7292071
    Abstract: A circuit and method thereof for sampling/holding signal is provided. The signal sampling/holding circuit comprises a first signal sampling/holding device, a second signal sampling/holding device, a target signal and a reference voltage. First, the first signal sampling/holding device is supplied with the reference voltage and the target signal. The reference voltage is disconnected from the first signal sampling/holding device before the target signal is. Similarly, the reference voltage is disconnected from the second signal sampling/holding device before the target signal is. Thus the target signal is respectively sampled and held in the first signal sampling/holding device and the second signal sampling/holding device.

  • Patent number: 7274009
    Abstract: A frame shuttered CMOS image sensor with simultaneous array readout. An array of CMOS pixels are printed on a silicon substrate. Within each pixel is a light sensitive region comprising a photo sensitive diode for converting photons into electrical charge and at least three transistors to permit reading of reset electrical charges and collected electrical charges and for re-setting the photosensitive diode. The sensor includes an array of signal and re-set readout capacitors located on the substrate but outside of the pixel array. Metal conductors printed in said substrate connect each pixel in said pixel array with a signal capacitor and a re-set capacitor in array of signal and re-set readout capacitors. Transistor switches printed in said substrate but outside of said pixel array are used to isolate the signal and re-set capacitors from each other and from the pixels.

  • Patent number: 6052664
    Abstract: The present invention describes an apparatus and method for generating phonetico-prosodic parameters of a predetermined message starting from a source message. The predetermined message comprises carriers and phrases. The phonetico-prosodic parameters of the carriers and the phrases are stored in a memory after having been generated off-line. The invention also comprises an apparatus and method for electronically generating a spoken message starting from phonetico-prosodic parameters, stored in said memory. The carriers comprise fixed parts and open slots filled with arguments. The phonetico-prosodic parameters of the arguments to be filled in in the open slots are generated at run time.

  • Patent number: 5727120
    Abstract: An improved apparatus for generating a spoken message is of the type formed by (i) first recording speech and (ii) then utilizing the recording so as to obtain at least one carrier, each carrier having at least one fixed part and at least one open slot, and then (iii) inserting an argument into each open slot. The improvement provides a phonetico-prosodic parameter generator for characterizing the message in terms of a sequence of phonetico-prosodic parameters for each carrier. An electronic memory stores the phonetico-prosodic parameters corresponding to each carrier and a controller constructs sequences of phonetico-prosodic parameters corresponding to the argument of each open slot. From the phonetico-prosodic parameters, a phonetics-to-speech converter generates a digital sound wave pattern which is converted, by a D/A converter, into an analog sound wave pattern. An output unit provides audible sound waves corresponding to the analog sound wave pattern.

  • Patent number: 5592585
    Abstract: An improved method for generating a spoken message is of the type formed by (i) first recording speech and (ii) then utilizing the recording so as to obtain at least one carrier, each carrier having at least one fixed part and at least one open slot, and then (iii) inserting an argument into each open slot. The improvement involves applying a prosody transplantation technique to the recording in order to obtain a sequence of phonetico-prosodic parameters for each carrier; identifying in each sequence sections of phonetico-prosodic parameters corresponding to the argument of each open slot; and substituting each of the sections by open slot data comprising at least position information indicating the position of each open slot.
