Publication number: 20090247117Abstract: A cellular telephone system has call management decisions made based on the exact geographic location of the mobile unit. These call management decisions include billing and taxing decisions, cell site selection, frequency selection and even cellular system selection. The decisions are continuously updated during a call whereby decisions can be made and changed regardless of where a call originated. Cell site location, and even cellular system selection, can be made in a specific manner to best serve the needs of the mobile user, the cellular system as well as the public. It is even possible for a cellular system to locate one or more of its cell sites in the geographic area served by another cellular system. In some cases, cellular systems might even share cell sites.Type: ApplicationFiled: June 11, 2009Publication date: October 1, 2009Applicant: EMSAT ADVANCED GEO-LOCATION TECHNOLOGY, LLCInventors: Everett Dennison, Timothy J. Duffy, Gregory T. Pauley, Scott L. Jones, Albert H. Pharis, JR., Warren P. Williamson, IV

Patent number: 5946611Abstract: A cellular telephone system includes a plurality of cell sites and a mobile telephone switching office. Call management, including selection of a cell site most appropriate for a call associated with a mobile unit, are made based on the geographic location of the mobile unit as opposed to the strength of the signal associated with the call. The geographic location of the mobile unit is precisely determined using a NAVSTAR global positioning system, or its equivalent. Each mobile unit includes a GPS receiver that receives information from a geostationary satellite to determine the precise location of the mobile unit. This position information is relayed to the cell site initially managing the mobile unit, and the mobile unit is handed off to a cell site that is most appropriate for the call. Initial selection of an entrance cell site is made based on signal strength, but further call management decisions are made based on location of the mobile unit.Type: GrantFiled: June 21, 1996Date of Patent: August 31, 1999Assignee: Sycord Limited PartnershipInventors: Everett Dennison, Edwin L. Nass, Timothy J. Duffy, Gregory T. Pauley, Scott L. Jones, Deborah J. Shale

Patent number: 5341804Abstract: A system for disabling an oximetric device when radiation-carrying channels are exposed to excess ambient radiation is disclosed. It includes a transmitter channel adjacent the sample to be measured, means for isolating the channel from the sample so that it does not carry radiation reflected from or transmitted through the sample, a detector for receiving the transmitted signal, if any, and means for disabling the output in response to the transmitted signal. Preferably, the transmitter channel runs parallel to other transmitter channels in the device, and is isolated from undue ambient light. The system preferably includes means for determining when the second transmitted signal exceeds background noise and the output is disabled when the second transmitted signal exceeds background noise.Type: GrantFiled: November 18, 1992Date of Patent: August 30, 1994Assignee: Medtronic, Inc.Inventors: Eric J. Fogt, James F. Kelley, Ralph M. Kerns, Timothy J. Duffy, David J. Draska
