  • Patent number: 8446362
    Abstract: A mouse is disclosed that comprises a main body, at least one function key, a position sensor and a data transmission line. The main body has a hand-shaped groove, a first surface disposed at a bottom of the hand-shaped groove, and a reverse surface to the first surface. The at least one function key is disposed on the first surface for producing at least one function signal. The position sensor is disposed on the reverse surface for sensing movement of the main body to produce a position signal. And the data transmission line is coupled to the main body for transmitting the function signal and the position signal to an electronic system or apparatus for operating the electronic system or apparatus.

  • Patent number: 7867716
    Abstract: The present invention includes an apparatus, system and method for stochastic sensing of an analyte to a protein pore. The protein pore may be an engineer protein pore, such as an ion channel at temperatures above 55° C. and even as high as near 100° C. The analyte may be any reactive analyte, including chemical weapons, environmental toxins and pharmaceuticals. The analyte covalently bonds to the sensor element to produce a detectable electrical current signal. Possible signals include change in electrical current. Detection of the signal allows identification of the analyte and determination of its concentration in a sample solution. Multiple analytes present in the same solution may also be detected.

  • Patent number: 7602982
    Abstract: Methods and systems for encoding, transmitting and decoding digital images by rate-distortion adaptive zerotree-based residual vector quantization are disclosed. A method of the invention includes receiving a digital image, transforming the digital image into the wavelet domain generating a pyramid hierarchy, losslessly encoding a top LL subband from the pyramid hierarchy, encoding other subbands by vector quantization based on a zerotree insignificance prediction, generating an encoded image from the lossless encoding and vector quantization encoding, transmitting the encoded image along a communications channel, receiving the encoded image transmitted along the communications channel, reconstructing a zerotree from the encoded image, vector quantization decoding subbands from the encoded image other than a top LL subband, losslessly decoding the top LL subband from the encoded image, reverse wavelet transforming the top LL subband and the vector quantization decoded subbands and outputting a decoded image.
