Abstract: A voice controlled surgical suite is provided for controlling a plurality of surgical apparatus by a single human. The system includes a voice recognition device adapted to recognize a plurality of predetermined speech commands from a single human and to generate a corresponding set of command output signals. A surgical table is operatively connected with the voice recognition device and is responsive to a first set of the command output signals to initiate selected surgical table movements. A surgical lighthead is similarly connected with the voice recognition system and is responsive to a second set of the command output signals to initiate selected surgical lighthead operations. In addition, surgical camera and task light devices are included in the system and are responsive to fourth and third sets of command output signals, respectively, generated by the voice recognition device to initiate selected surgical camera and surgical task light operations.

Abstract: An acoustic imaging device for providing an image of a body in a medium, includes a plurality of acoustic transmit elements and a plurality of acoustic receive elements, an apparatus for activating one of the transmit elements to generate an ultrasonic signal, an apparatus to selectively receive and record from each of the receive elements a set of data representing a phase, amplitude and transit time of the ultrasonic signal, a first computing apparatus for calculating a velocity map of propagation velocity values in each of a plurality of volume elements including the body and the medium using the data set, and a second computing apparatus for calculating a reflectance map, including a coherent sum of reflectance values at selected points in the plurality of volume elements using the data set.

Abstract: A circuit to improve the sensitivity of a receiver by more than 3 dB. According to the invention, conventional predetection integrators are replaced by a circuit to compute the correlation of the received signal with a delayed version of the received signal. The time delay is selected such that the noise in the signal and the delayed signal are statistically independent.
