  • Patent number: 10212462
    Abstract: An integrated intelligent server based system includes at least one autonomous system containing one or more analytical server for unified multiple sensory data mapped multi-modal or multi-sensory imagery analysis, generating analysis result and streaming of the sensory data with the generated analysis result to the receiver module. A fail safe and fault tolerant technique to generate, store and stream the multi-sensory images to the receiver module is also proposed. Once received, the receiver module extracts the sensory data and the results of the sensory data analysis from the image and video using a suitable decoder. The integrated intelligent server based system would enable embedding the results of the sensory data analysis within the image itself and streaming the multi-sensory image embedded with the results of said sensory data analysis to a receiver module. This results in adopting this new concept in Internet of Things scheme of activities as well.

  • Patent number: 9178494
    Abstract: A symmetric discrete-time square-root-raised-cosine filter may be utilized to process a serial input signal and to produce an output square in each clock cycle. The filter may be adapted to decrease the computational complexity of the resulting calculations, making the filter amenable to use in power sensitive applications and in those situations where the available processor's performance is relatively limited.

  • Patent number: 7274393
    Abstract: A sensor for color and depth information capture is disclosed. A filter passes selected wavelengths according to a predetermined pattern to the sensor. The sensor measures light intensities passed by the filter. In one embodiment, the wavelengths passed by the filter correspond to red, green, blue and infrared light. The intensity values can be used for interpolation operations to provide intensity values for areas not captured by the sensor. For example, in an area corresponding to a pixel for which an intensity of red light is captured, interpolation operations using neighboring intensity values can be used to provide an estimation of blue, green and infrared intensities. Red, green and blue intensity values, whether captured or interpolated, are used to provide visible color image information. Infrared intensity values, whether captured or interpolated, are used to provide depth and/or surface texture information.

  • Patent number: 7245651
    Abstract: A dual mode filter for mobile communication may implement two disparate cellular systems such as GSM and W-CDMA. The same transceiver may be utilized to selectively receive and transmit in either of the two systems. When the system is in a GSM area, the system sends and receives GSM signals using programmable filters. Two cascaded digital decimation filters may substitute for one narrow band digital decimation filter in conventional designs. One of the filters is a multi-band digital decimation filter with N bands and the other of the digital filters is used to reject the N?1 multi-band of the system. The number of taps on each filter may selectively be set to implement either GSM or W-CDMA. In addition, the output for the system may be set to be the output of the first filter, in the case of a W-CDMA system, or the combination of the two cascaded filters in a GSM system.
