A zone effective ground-position-responsive wifi hotspot system comprising a first antenna arranged within a zone, responsive to any of a wide variety of various manufacturers different wireless ground-position-indicative RF communication devices, a transmission line for transmitting RF signals to and from the wide variety of various manufacturers different ground-position-indicative RF communication devices utilized within the zone, and a control unit arranged in a link between the first antenna arranged within the zone, and the transmission line, the control unit enabled to be responsive to a variety of different wireless ground-position-indicative RF communication devices, to enable controlled wireless RF communication to and from the zone.

Wifi hotspot arrangement

A system for enabling wireless near-field hot-spot communication between a wide variety of wireless ground-position-indicating personal communication devices being utilized within a zone and a further communication network outside of the zone.

Mobile wifi arrangement

A system for enabling the wireless use and billing for that use of any of a wide variety of different manufacturers personal, ground-position-indicating enabled, wireless electronic rf communication devices in a zone, and a network outside of the zone.

Wireless hotspot billing arrangement for a wide variety of personal communication devices

A trocar assembly for providing a pressurized insufflation fluid into a patient cavity and for providing sealable access to the patient cavity by a surgical instrument. The assembly comprises an inner tubular member having a proximal end and a distal end. An outer tubular member is disposed about the inner tubular member, the outer tubular member having a proximal end and a distal end. The distal end of the inner tubular member and the distal end of the outer tubular member define a trocar seal nozzle arranged therebetween.

Continuous gas flow trocar assembly

A hot spot system for permitting wireless communication for a wide variety of various manufacturers different wireless personal communication devices in an rf restricted environment, wherein the different wireless personal communication devices each have a radiative antenna, and wherein the hot spot system is arranged to permit wireless, controlled communication between a wide variety of various manufacturers of different personal communication devices located within the rf restricted environment and other communication devices located outside of the rf restricted environment.

Wireless hotspot arrangement

The present invention comprises a docking system for connecting a portable communication device to a further signal transmission line. The docking system may be arranged within a workstation such as a desk or a tray. The system may also envelope a room in a building or be located in a vehicle, to control and restrict the radiative emission from the communication device and to direct such radiation to a further remote antenna and or signal distribution system connected to the transmission line.

Personal wireless communication device connectivity arrangement within an RF restricted environment

Various embodiments of the present invention comprise a signal generator for sending an electrical signal from an expandable, flexible layer of material, the signal generator comprising an upper layer of flexible, resilient material and a lower layer of flexible, resilient material which between them define a cavity for enclosing an expandable material such as a cellular foam or gas, whereupon localized distortion of one of the layers of flexible material, effects a signal generation within the structure, which is transmissible through a proper circuit to an outside electrical device. A circuit may be arranged adjacent a plurality of said keys which senses when several of said keys are depressed in a skewed or sideways manner, so as to effect movement of a cursor or pointer on a monitor in communication with a processing unit and said keyboard.

A trocar assembly for use in surgery in a patient, comprising an elongated outer tubular member having a first or proximal end and a second or distal end. The proximal end has a housing enclosing a fluid pressure chamber therein. The distal end of the outer tubular member has a gaseous fluid discharge arrangement therethrough, through which a medical instrument is disposed for surgical manipulation of the patient.

Gas flow trocar arrangement

The present invention comprises a docking system for connecting a portable communication device to a further signal transmission line, The docking system may be arranged within a workstation such as a desk or a tray, The system may also envelope a room in a building or be located in a vehicle, to control and restrict the radiative emission from the communication device and to direct such radiation to a further remote antenna and or signal distribution system connected to the transmission line.

A cannula assembly for the maintenance of an operative pneumoperitoneum in a patient comprising an elongated cannula having a proximal end and a distal end. A removable valve is securely arranged in the proximal end of the cannula to provide a seal and minimize the escape of gas introduced into the patient's pneumoperitoneum when an operative instrument is passed therethrough.
