  • Patent number: 10499003
    Abstract: A diversity receiver synchronizes and mixes multiple input signals. In one embodiment, the receiver demodulates the multiple input signals prior to synchronizing, converts the demodulated multiple input signals from analog signals to digital signals, synchronizes the demodulated digital signals, converts the synchronized demodulated digital signals to analog signals and mixes the synchronized demodulated analog signals based on a characteristic of the input signals existing prior to the demodulating.

  • Patent number: 10493367
    Abstract: Described herein is an apparatus and method to convey an object through the air in a controlled and repeatable manner. The apparatus may comprise an object attached to at least one resilient member, the resilient member or members constraining object movement in a substantially vertical y-axis direction. The apparatus may also comprise at least one support member coupled to the at least one resilient member, and the support member or members constrain object movement in a substantially horizontal x-axis direction. In use, the resilient member is energised, movement initiated, and object movement then occurs in an x-axis and a y-axis direction, the movement path substantially governed by the resilient member(s) and the support member(s). The apparatus and method may allow the object to experience a variety of movement sensations, one being the feeling of flight or gliding.

  • Patent number: 10376820
    Abstract: A pumped or gravity flow rotating drum screen removes unwanted solids from a flowing fluid. The drum screen may comprise: a housing having a fluid inlet end, a solid discharge end and an area between the two ends, the fluid inlet permitting a flow of influent containing unwanted solids into a hollow portion of a drum screen positioned lengthwise in the area between the two ends of the housing, the screen comprising a filter medium that retains at least a portion of the unwanted solids within the hollow portion of the drum screen and which produces a liquid effluent that is discharged from an outer surface of the drum screen, the retained solids being removable via the solid discharge end; a drive assembly configured to rotate the drum screen about an axis running the length of the drum screen; and one or more stabilization pad assemblies in contact with one or more rings circumscribing the outer surface of the drum screen at one or more locations.

  • Publication number: 20190236962
    Abstract: Techniques are described for the exchange of control signals between a controlled unmanned aircraft (i.e. drone) and a ground control station and for the transmission of communication signals, such as video, from the drone to the ground control station so that the signals are more difficult to intercept or jam. The video signal transmitted from the drone can be an analog RF signal employing one or more of video “scrambling”, RF signal inversion, hopping, usage of a wide frequency range and other techniques. To secure the control signals between the drone and the ground control station, techniques can include hopping, encryption and use of a wide frequency range.

  • Patent number: 10141996
    Abstract: A communication system is used to receive information from mobile sources. The system includes a plurality of antennas including multiple disjoint sets of multiple antennas configured to receive signals from the multiple mobile sources. At least a subset of the antennas have coverage areas that overlap with antennas in another set of the multiple disjoint sets of multiple antennas. The communication system also includes multiple receivers and multiple signal paths including one signal path for each set of multiple antennas. Each signal path is configured to provide outputs from a corresponding set of multiple antennas of the multiple disjoint sets of antennas to each of the multiple receivers. Each of the receivers choose to output information from one or more of the signal paths based on one or more characteristics of the signals received from the signal paths.

  • Publication number: 20180169529
    Abstract: A sensor acquisition and analytics platform for enhancing interaction with adult devices. More specifically, the integration of social networking and gamification (i.e., adding game-like features to the interactions between adult devices and the user(s)) frameworks towards enhancing user interactions and joint activities surrounding adult devices, services, and/or content is introduced. Additionally, analytics and learning intelligence (in the form of adaptive learning or behavioral pattern prediction) may be implemented (either as part of the framework or separately), which serves to discover appropriate connections, mappings, or associations between adult device characteristics/settings and measured sensor information (including user biometrics, forces, pressure, motion, etc.).
