    摘要: A health and usage monitoring system for use in monitoring health and usage of one or more components of a vehicle. In various embodiments, the present invention uses at least one roving wireless sensor that can be temporarily placed in a first position to monitor one or more components of the vehicle and then moved to another position to monitor one or more other components of the vehicle, thus reducing the total number of sensors used to monitor the vehicle. In some embodiments, a system according to the present invention may comprise at least one or more roving wireless sensors. Other embodiments may comprise one or more roving wireless sensors used in conjunction with one or more wired sensors. The present invention also provides similar embodiments for a method of monitoring the health and usage of one or more components of a vehicle.

    摘要: Synchronizing at least one wireless sensor includes sending at least one reference message along with a request for acquired data from an access point to the at least one wireless sensor, where the reference message includes a first timestamp indicating when the reference message was sent according to time of a clock of the access point, receiving from the at least one wireless sensor a response that includes the requested data, the first timestamp, and at least one other timestamp corresponding to time of a clock of the at least one wireless sensor, and determining a relative clock offset of the at least one wireless sensor using the timestamps.

    摘要: Synchronizing a wireless sensor includes receiving a first command at the wireless sensor, noting a first timestamp value indicating when the first reply is sent, responding to the first command with a first reply, receiving a second command at the wireless sensor that contains a second timestamp value indicating when the first reply was received and a third timestamp value indicating when the second command was sent to the wireless sensor, noting a fourth timestamp value indicating when the second command was received by the wireless sensor, and determining an offset at the wireless sensor using the first, second, third, and fourth timestamp values. The presence of the first timestamp value may be interpreted as a request to provide timestamp information for synchronization. An access point may communicate with the wireless sensor.

    摘要: The controller controls the amplifier and a modulated power supply, supplying power to the amplifier, by detecting an RF envelope of a signal input to the amplifier. Predistortion of the amplifier synchronous with changes of bias is provided using a look-up table. Specifically, amplitude predistortion, phase predistortion and DC voltage level adjustments are made to the RF signal. Adjustments for gain and phase variation are applied synchronously with bias changes.
