  • Patent number: 8831675
    Abstract: A mobile communication device (102) contains both a WAN modem (122) and a PAN modem (134) which operate on interfering radio frequencies. To mitigate interference, and still permit real-time communication operation, the PAN is prevented from transmitting while the WAN is receiving (714). The PAN carries the real-time data via an active link (144) between the PAN modem and a remote device (142). The active link uses a retransmission protocol, which allows recovery of suppressed packets within a given period. The PAN modem is disabled for periods shorter than a maximum time which guarantees success transmission or retransmission of the PAN data. To further aid successful operation of the PAN retransmission operation, the WAN base station aggregates data into a single downlink burst.

  • Patent number: 8774828
    Abstract: The invention relates to a system that enables power to be selectively applied to GPS circuitry in a cellular telephone or other mobile device only when a specific user input is detected. In one embodiment, power to the GPS circuitry may be enabled only when the user strikes the keys “9-1-1.” In other embodiments, other types of GPS enablement or disablement may be employed, such as selectively decoupling the GPS antenna. In another embodiment, the user may depress a privacy bypass button, which alternately enables and disables power to the GPS circuitry. Cellular telephones or other communication devices may therefore activate GPS location service during an emergency call, or when a user wishes to allow their location to be determined, but protect the privacy of that user's location and movement at other times.

  • Patent number: 8713241
    Abstract: The present invention discloses a portable computing device (100) including a processor (102), alternate memory (106), and a DRAM memory (108). Under normal operating conditions, providing full functionality of the device, a full code instantiation in the DRAM is executed, providing operating system, user interface and application execution functionality. A reduced code instantiation (114) which duplicates certain elements of the operating system, user interface, and application code is maintained in the low power memory. When a condition occurs that dictates or allows, execution is switched from the full code instantiation to the reduced code instantiation, and the DRAM is shut off.

  • Patent number: 8554271
    Abstract: A mobile communication device (102) includes both a wide area network (WAN) radio modem (122), and a personal area network (PAN) radio modem (134), which operate on similar frequencies. When the both the WAN and PAN modems are operating and carrying time-sensitive data, the WAN modem disables transmission by the PAN modem when the WAN modem is due to receive data from a WAN base station (406), including neighbor scans. The duration and frequency of disabling the PAN modem is controlled so that the retransmission is successful.

  • Patent number: 8156320
    Abstract: The present invention discloses a portable computing device (200) including a processor (202), non-volatile memory (206), and a volatile memory (208). An execute in place (XIP) kernel (210) stored in the non-volatile memory is executed immediately upon powering up the device. As the XIP kernel is executed, the processor maintain state and context information (212) in the volatile memory. The XIP kernel includes user interface and application segments, allow the user to perform some functions immediately upon powering up the device. While executing the XIP kernel and full code instantiation (214) is loaded into the volatile memory. The full code instantiation includes identical code as is in the XIP kernel, in addition to other code. Once loaded, execution is switched (412) from the XIP kernel to the full code instantiation, providing full functionality of the device.

  • Patent number: 7801066
    Abstract: A mobile communication device (102) includes a wide area network (WAN) modem (122) for communicating over a wireless WAN. During a voice call, the WAN modem operates in a power save mode (206) but must occasionally scan for handover candidate base stations (208). The modem goes directly from the power save mode to a scan mode at an agreed upon time, first selected by the mobile communication device, but which may be modified by the base station.

  • Patent number: 7536186
    Abstract: A system, computer readable medium, mobile subscriber device and method determine that the device (306), operating on a first communications system is detecting a triggering event, which may be the detection of a wireless local area network border cell (210) or a degradation in signal quality. The device (306) then initiates a registration sequence with a second wireless communication system if the device (306) has detected the triggering event, determines the speed and/or displacement of the device (306), and conducts any present and subsequent calls via the second wireless communication system if the speed and/or displacement of the device exceeds a predetermined threshold. The registration sequence may be aborted if at least one of the speed and displacement of the device (306) does not exceed predetermined thresholds. Movement of the device (306) may be determined by an accelerometer (314) or GPS chipset.
