摘要： 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.

摘要： 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. The surgical apparatus has manual controls to provide redundancy, and to override voice control signals as needed.
