Abstract: A cellular, PDA communication device and communication system for allowing a plurality of cellular phone users to monitor each others' locations and status, to initiate cellular phone calls by touching a symbol on the touch screen display with a stylus which can also include point to call conferencing calling. Each participant's cellular phone PDA device includes GPS navigation receiver with application software for point to call cellular phone initiation to participants and geographical entities including vehicles, persons or events, conference calls and video transfers. The method and system also includes automatic shifting from GPRS/EDGE/CDMA/1XEVDO to SMS when any of the cellular phones in the communication network is in the voice mode and in use and for automatic shifting back to GPRS/EDGE/CDMA/1XEVDO upon completion of the voice phone call.

Abstract: A system and method provide for establishment and use of permission sets for subscribers where client applications in a wireless communication environment are requesting location information for a particular wireless communications device from a provider of such information. The system described herein provides the capability for a wireless communications device operator to establish a profile wherein limitations may be placed on the provision of such location information based on such things as the requesting party, spatial and temporal limitations, as well as granularity. The system described herein may be further configured such that an authentication process is preformed for client application seeking location information which would require the registration of such client applications with a centralized processing system.

Abstract: An exposure control system for photographic apparatus utilizing pulse driven shutter-diaphragm light regulating elements in conjunction with a follow focus mechanism which in response to the location of the light regulating elements terminates the driving operation thereby automatically selecting an aperture value for flash operation. The follow focus mechanism locates a sensor switch in the path of travel of a pair of aperture defining blades as a function of scene ranging such that the sensor switch is actuated by the blades as the latter are displaced to the selected switch location and, in turn, terminates further pulses to the stepper motor thereby stopping the blades at a predetermined location defining a selected aperture value.
