  • Patent number: 11922742
    Abstract: The system has a processing unit that collects input data and a peripheral storage device, connected to the processing unit via an interface system, for recording event data in a non-volatile memory, wherein the event data are input data stored for a recording time period relative to a time zero representing a time when a trigger event occurs. The peripheral storage device has also a volatile memory, and the data logging system stores the input data in the volatile memory of the peripheral storage device, when input data are being collected, and, when a trigger event occurs, makes a copy of stored input data as a backup from the volatile memory of the peripheral storage device into the non-volatile memory of the peripheral storage device.

  • Patent number: 8055212
    Abstract: A wireless communication transmitter is configured to determine transmitter phase shift, and correspondingly includes a derivation circuit, one or more slope polarity tracking circuits, and a phase shift computation circuit. The derivation circuit derives a reference signal from a signal input to the transmitter and a feedback signal from the transmit signal corresponding to that input signal. So derived, differences in the reference and feedback signals reveal the effect the transmitter has on the transmit signal. Accordingly, the transmitter focuses on differences in the polarities of the reference signal's slope and the feedback signal's slope to determine the effect the transmitter has on the phase of the transmit signal. That is, the slope polarity tracking circuits track the slope polarities of the reference and feedback signals, while the phase shift computation circuit computes the transmitter phase shift as a function of differences in those tracked slope polarities.
