  • Patent number: 8954230
    Abstract: In telematics device mounted to a vehicle, an auxiliary processor detects an interrupt from an accelerometer and forwards the interrupt to a main processor—the interrupt wakes up the processor from a sleep mode. The main processor may then compare vehicle voltage and/or a value for a speed parameter to predetermined criteria to determine whether the interrupt was a false positive or if the accelerometer missed a detection of a user cranking up the vehicle. The main processor may also enter a conditional state if monitored information meets a minimum threshold. During the conditional state, the processor may operate according to rules for a current operational state and also according to rules for a changed state. The threshold for deeming a changed operational state is higher than for entering a conditional state to evaluate whether a change of operational state (i.e., on to off, or off to on) occurred.

    Abstract: Systems and methods are disclosed which relate to mitigating the detrimental effects of interference to electronic devices from mobile telephones utilizing any form of time-domain multiplexing technology. A wireless transmitter inside the mobile telephone broadcasts a warning transmission which can be received by affected devices. Once the warning transmission is received by an affected device, the device activates a blanking circuit comprising an actuator and a switch or switches. The switches open for the duration of the interference so that the user does not receive undesired output such as: noise through a speaker, noise through a microphone, or other interference with electrical signals.

  • Patent number: 8897828
    Abstract: Power control in a wireless network is disclosed. Transmit power control (TPC) commands may be accumulated by a user equipment (UE). If accumulation is enabled, the UE may receive on a single physical channel an allocation of a scheduled uplink resource and a TPC command. The TPC command may be accumulated with other received TPC commands. A transmit power for an uplink communication based on both the path loss and the accumulated TPC commands may then be calculated by the UE. If accumulation is not enabled, the UE may receive an allocation of a scheduled uplink resource to transmit data at a calculated power level.

  • Patent number: 8891598
    Abstract: A communication device operating in time division duplex (TDD) mode using multiple antennas is provided herein. The communication device uses receive channel estimation measurements to perform transmit beamforming and multiple input multiple output (MIMO) transmission, based on self-calibration of the various up/down paths via a method of transmission and reception between its own antennas, thus achieving reciprocity mapping between up and down links. Either user equipment (UE) or a base station may routinely perform this self-calibration to obtain the most current correction factor for the channel reciprocity to reflect the most current operating conditions present during TDD MIMO operation.
