| 20100086092 | Method of Efficiently Synchronizing to a Desired Timeslot in a Time Division Multiple Access Communication System - The time required for the receiving device to synchronize to a desired timeslot is reduced. In operation, a transmitting device selects a synchronization pattern associated with the desired timeslot that is at least mutually exclusive from synchronization patterns associated with other timeslots on the same frequency in the system. Once selected, the transmitting device transmits a burst embedding the synchronization pattern that was selected, where appropriate. If the receiving device detects the synchronization pattern, it immediately synchronizes with the timeslot with confidence that it is synchronizing to the desired timeslot. Using synchronization pattern associated with the desired timeslot that is at least mutually exclusive from synchronization patterns associated with the other timeslots on the same frequency also improves spectral efficiency in direct-mode transmissions, thus allowing more than one subscriber unit to simultaneously transmit in direct mode on a frequency without interfering with other transmissions on the frequency. | 04-08-2010 |

| 20090204325 | TRACKING VEHICLE LOCATIONS IN A PARKING LOT FOR DEFINITIVE DISPLAY ON A GUI - A computer implemented method for displaying on a map a definitive image of precise locations of multiple mobile objects such as vehicles in a lot. The lot is mapped digitally to display precise locations of sub-areas of different types, such as parking and movement slots and their raw, approximate distances from vehicles are determined from approximate coordinates of vehicles obtained remotely. A data base of vehicle and sub-area types is established and a vehicle placement matrix is determined providing probabilities of respective sub-areas being occupiable by respective vehicles derived from business environment rules based on compatibilities of respective vehicle types with respect sub-area types. Raw, approximate distances of vehicles from sub-areas are divided by the probabilities to provided adjusted distances, sub-areas ranked by least adjusted distances and the respective vehicles placed in their top ranked sub-areas for more accurate display of location on a GUI. | 08-13-2009 |
