Abstract: An entertainment system has a personal computer as the heart of the system with a large screen VGA quality monitor as the display of choice. The system has digital satellite broadcast reception, decompression and display capability with multiple radio frequency remote control devices which transmit self identifying signals and have power adjustment capabilities. These capabilities are used to provide context sensitive groups of keys which may be defined to affect only selected applications running in a windowing environment. In addition, the remote control devices combine television and VCR controls with standard personal computer keyboard controls. A keyboard remote also integrates a touchpad which is food contamination resistant and may also be used for user verification. Included in the system is the ability to recognize verbal communications in video signals and maintain a database of such text which is searchable to help identify desired programming in real time.

Abstract: The present invention relates to an apparatus and method for penetrating body tissue. The apparatus includes a handle member having a gas pressure chamber positioned therein and a shaft member having a longitudinal bore therethrough and one end connected to the handle member. The longitudinal bore in the shaft member is in cooperative alignment with the gas pressure chamber to facilitate the passage of gases therethrough. The apparatus also includes a pressure indicating system which provides a visual indication when the shaft member has penetrated the body tissue.

Abstract: The present invention relates to a trocar and method for penetrating body tissue. The trocar includes an obturator assembly and a cannula assembly. The obturator assembly has an obturator shaft with a distal end portion adapted to penetrate body tissue and at least one channel extending between a proximal end portion of the shaft and the distal end portion. A pressure indicating system is positioned at the proximal end of the shaft and is provided to respond to the passage of gases through the channel and provide a visual indication when the distal end has penetrated the body tissue. A safety system is associated with the obturator shaft and responsive to gas pressure to shield the distal end portion of the shaft after penetration of the body tissue.

Abstract: The present invention relates to a trocar adapted to provide a surgeon with an indication when the trocar has penetrated body tissue. The trocar includes an obturator assembly and a cannula assembly. The obturator assembly has an obturator housing and an obturator shaft. The shaft has a proximal end portion connected to the housing and a distal end portion adapted to conduct electricity and penetrate body tissue. An electric connection assembly is associated within the obturator housing and provides a conductive path between the conductive portion of the obturator shaft and an outer surface portion of the obturator housing. The connection assembly is also adapted to receive an external electrical connector.
