The control console communicates to at least one medical device, and at least one peripheral module associated with the medical device if needed. The control console has a microprocessor for processing data to direct an operation of the medical device.

Abstract: A system for controlling an electrosurgical electrode of a medical device includes a hand-held electrosurgical electrode having cutting probe. A return electrode is positioned remote from the electrosurgical electrode. An RF generator is coupled to the electrosurgical electrode and to the return electrode, and includes an RF amplifier. The RF generator generates an RF signal at a first RF power level for tissue cutting and generates the RF signal at a second RF power level greater than the first RF power level to initiate tissue cutting. A sensor monitors an electrical characteristic associated with the electrosurgical electrode. A controller coupled to the RF amplifier maintains a desired RF power output and a desired RF duty cycle at the first RF power level by adjusting a DC input voltage applied to an output stage of the RF amplifier based on the monitored electrical characteristic associated with the electrosurgical electrode.

Abstract: A system includes a tubing set, having a pair of bladders, and a fluid drive system. When the tubing set is filled with fluid, one of the bladders is moved to generate a dynamic pressure wave in the fluid in the tubing set, while the other of the bladders is in contact with a pressure sensor which senses the pressure in the tubing set. When connected to a clogged enteric feeding tube, the system can be controlled by a control system to find the resonate frequency of the combination of the tubing set and the feeding tube, and fluid pressure waves at that frequency can be generated through the one bladder to free the clog in the feeding tube.

Abstract: A mobile telecommunication unit (20) provides two-way remote viewing of images and real time audio. The self-contained, portable unit (20) communicates directly with a similar unit at a remote location across POTS lines, cellular, ISDN, T-1, and satellite communication links. The unit (20) includes mass storage for archiving images. Input devices (25) for each unit include a digital camera (36) through a PCMCIA card, electronic stethoscope, telephone handset, speakerphone, external microphone, and serial and parallel ports. The output devices include a full color screen (22) for viewing local and received images and a speaker for audio output. A hard copy of images can be made by a video printer or desktop printer (42). Images can be uploaded to a PC.

Abstract: A system and method for managing, reducing, or eliminating the deleterious effects of the operation of energy emitting instruments on imaging systems. The system and method of the invention can be built into the structure of an imaging system, or can be configured to adapt to existing imaging systems. An embodiment of a system incorporating features of the invention has an interference bar detector coupled to an interference bar acquisition device which relays information regarding a bar of interference to a processor which identifies the position and velocity of the interference bar moving across an image frame or image display. Based on the position and velocity of the interference bar within the image frame, the processor then computes the necessary corrections to the gating and timing of the operation of the energy emitting instrument so as to fix the position of the interference bar at a perimeter of the image display.

Abstract: The present invention relates to a dental drilling system having a programmable control unit. The control unit controls operating parameters of the drilling system, such as the direction of rotation, the speed of rotation and the torque of a tool bit of a dental drill, as well as the irrigation fluid flow rate generated by a pump and the intensity of light generated by a light source. The control unit can be programmed with a number of sets of data values. Each set of data values represents a desired value for each of the operating parameters to be controlled. Also, each set of data values corresponds to a different step in a dental operation. Thus, for each step of a dental operation, a surgeon can choose a desired set of operating parameter values from those sets that have been preprogrammed. The control unit then controls the operating parameters to achieve and maintain the values represented by the selected set of data values.

Abstract: A multiplexer is employed for connecting a plurality of microphones and sending an encoded signal over a single line where it is then decoded, filtered and processed such as by amplification.The multiplexer switches from one microphone channel to the next over an eight channel track, typically at about 2.times.10.sup.6 times/second, and produces a sample duration of about 0.5 microseconds for each channel. Cross talk is reduced by means of a blanking signal which causes the multiplexer to terminate a sample pulse about 120 nanoseconds prior to the onset of a succeeding pulse; this produces a distinct cut-off between sample pulses.A synchronizing pulse at the end of the last (i.e. eighth) channel terminates each eight channel domain switch over to produce a scan cycle. This is combined with a clock signal in a data encoding circuit.The synchronizing pulse, sample pulse and blanking signal are then fed to a signal decoder which, after filtering, converts the sample pulse back to a discrete (i.e.
