摘要： A system for receiving local point of interest data is presented. The local point of interest data for a local geographic area is received by a geographic location device via a supported protocol. The local point of interest data includes information regarding one or more local points of interest in the local geographic area. The received local point of interest data is cached with existing point of interest data and maps within a cache in the geographic location device. Then, it is determined whether any time-sensitive point of interest data in the cache has expired. In response to determining that time-sensitive point of interest data in the cache has expired, the expired time-sensitive point of interest data is removed from the cache to form current local point of interest data for the local geographic area. Then, the current local point of interest data is displayed in a display device.

摘要： A method, apparatus and article of manufacture for compensating for carrier frequency error is disclosed. An FM signal is received from an antenna and the received FM signal is provided to receiver. The receiver takes the FM signal at the carrier frequency and outputs a baseband signal. This baseband signal is then processed by a DSP which provides carrier frequency compensation and decoding to produce a data stream that a microprocessor provides to a host device. Frequency differences between the FM carrier frequency and the frequency used to demodulate the FM signal can shift the DC bias level of the baseband signal. The DSP compensates for such frequency difference by using a receive compensation value and applying it to each received signal sample. When transmitting, data to be transmitted is provided from the host device to the DSP via a microprocessor. The DSP provides encoding and carrier frequency compensation of the data to provide an baseband signal to a transmitter that modulates the baseband signal to produce a FM signal at a desired carrier frequency. Frequency differences between the desired FM carrier frequency and the frequency used to modulate the baseband signal can produce errors in receiver systems. The DSP compensates for such a frequency difference by using a transmit compensation value and applying it to each encoded signal sample.

摘要： Described is a method, apparatus, and article of manufacture to minimize radio data modem receive errors when a base station keys up. It applies to an intermittently keyed, multiple base station, single frequency reuse, FM modulated, radio data network such as the ARDIS network. Compensation is provided for the fact that each base station in the network may have a different transmit FM deviation level. Since these networks typically use the same base station to transmit to any one radio data modem over periods of time, and since the modem receiver can measure and remember the FM deviation level of each base station, a modem can compensate by using the FM deviation value of its "present" base station as the starting value for its automatic deviation control algorithm. By seeding the algorithm with the actual value for the "present" base station, receive data errors are reduced during the critical time when the base station is keying up. As the geographical position of the modem changes, or as radio conditions vary, the network may select a different base station to transmit to a modem. The modem will detect this change, and dynamically change its compensation to match the new "present" base station.

摘要： A method and apparatus in a data processing system for binding a plurality of server daemons to a destination address and port. A request for a connection from a client is routed using a destination address. A server daemon within the plurality of server daemons is selected to form a selected server daemon. The request is routed to the selected server daemon by changing the destination address to a server address for the selected server daemon. When a response is returned, source address in the response is changed to the original destination address.
