  • Patent number: 8422470
    Abstract: A communication system comprises a main communication device including a first communication unit executing wireless communication by a first method (mainly for voice data communication) and a second communication unit executing wireless communication by a second method (for communication of data other than voice data at a higher transfer rate) and an auxiliary communication device (operating on a secondary battery) including first and second auxiliary communication units executing wireless communication with the first and second communication units by the first and second methods, respectively. Whether communication of data (except voice data) should be executed by the first method or by the second method is determined based on the amount of the data. When the first method is selected, the data is segmented in prescribed data units and the communication of the segmented data is executed by the first communication unit and the first auxiliary communication unit by the first method.

  • Patent number: 8388539
    Abstract: Surgical operation supporting apparatus and method is disclosed in which based on a high-definition tomographic images of an operation site produced before surgery, a three-dimensional model of the operation site is generated, and a surface of the operation site is optically measured during the surgical operation, and further, first position information that represents a three-dimensional position of each of points on the surface is acquired. An unexposed portion of the operation site is measured with ultrasonic waves during the surgical operation, and second position information that represents a three-dimensional position of each of points in the unexposed portion is acquired. Based on the first position information and the second position information, displacement and distortion at a portion whose three-dimensional position is not known in the three-dimensional model is estimated to obtain an estimated result.
