  • Amphibious transport system
    Patent number: 10464383
    Abstract: An amphibious transport apparatus includes forward and aft ends, a pair of spaced apart pontoons including tracks, and a transversely extending structure, which can include a platform, that spans between the pontoons and connects the pontoons together. The amphibious transport apparatus further includes a sled vessel that can be used to transport materials or personnel.

  • TECHNIQUES FOR LOCATION STATE DETERMINATION BY AN ELECTRONIC DEVICE
    Publication number: 20190313206
    Abstract: The present disclosure provides for dynamically determining locations of an electronic device. For example, the electronic device may determine a location state transition condition using one or both of a location measurement or an activity status of the electronic device. The electronic device may further determine whether the location state transition condition satisfies a location state transition threshold triggering an entry or exit to or from a first location state. The electronic device may further transition from the first location state to a second location state different from the first location state based on a determination that the location state transition condition satisfies the location state transition threshold.

  • Sampling clock alignment and time offset signaling for symbol-aligned frames
    Patent number: 10397026
    Abstract: Systems and methods for sampling clock alignment and time offset signaling are disclosed herein. A transmitter broadcasting symbol-aligned frames at multiple baseband sampling rates can benefit from generating the frames to have durations that can be represented by an integer number of samples at two or more of the baseband sampling rates. In some embodiments, a transmitter adds samples to a frame to ensure that its duration meets such a criteria. Furthermore, the problem of signaling network time in symbol-aligned frames is simplified by sampling clock alignment. Approaches for signaling time offset of a transmission to the nearest millisecond boundary are also presented.

  • ENERGIZING COIL WOUND ON MAGNETIC CORE AND OSCILLATORY TESTING OF TRANSFORMER
    Publication number: 20180259565
    Abstract: Methods and apparatus for energizing a wound component are described. In one arrangement, a method of energizing a component with an alternating voltage is provided. The component comprises a coil wound on a magnetic core. The method comprises applying a voltage across the coil that has a first waveform during a first time period and a second waveform during a second time period. The second time period is subsequent to the first time period. The second waveform comprises an oscillating function comprising a sequence of identical waveforms. The first waveform is such that if the coil had zero electrical resistance the variation of flux density in the magnetic core with time would change sign at least once during the first waveform.
