  • Patent number: 11982922
    Abstract: A system is described. The system includes HNLF for generating an optical frequency comb and a single mode fiber for reducing a pulse duration of comb. The system includes a FRM to reflect the light in back propagation through the HNLF and the single mode fiber. Perturbations in a state of polarization caused by the HNLF and the single mode fiber are cancelled between the forward propagation and the backward propagation. The optical frequency comb may then be polarization maintaining without an active component such as a polarization controller and a feedback circuit.

  • Patent number: 11983809
    Abstract: A method for order independent transparency is described. The method includes rendering objects into an A-buffer by a GPU. A CPU performs dynamic memory allocation to allocate the A-Buffer based on a size of the previous frames A-Buffer. By allocating the A-Buffer based on a previous frame, a GPU-to-CPU synch point may be removed. Depending upon a size of the A-Buffer, not all objects may fit into the A-Buffer. The method may additionally include creating an R-Buffer with the identification of partially stored objects and removing the partially stored objects from the A-Buffer prior to blending.

  • Patent number: 11979203
    Abstract: A set of stators of a linear induction motor are mounted on a track. A three-phase current is provided to each of the stators, such that a traveling magnetic field (TMF) is created by the stators along the length of the track. The traveling magnetic field includes a magnetic flux corresponding to a stator excitation modulated with a message signal. A rotor includes a series of conductor plates. As the traveling magnetic field passes through the conductor plates, a current is induced in the plates by induction. Such current then generates an opposing magnetic field causing the plates and the vehicle to be propelled. Each phase may first be modulated with a message signal, before being provided to the stator. The current at the rotor is then demodulated to realize the message signal. A doppler shift due to the speed of the rotor relative to the stator is corrected.

  • Patent number: 11971728
    Abstract: A hierarchical modular arbitration architecture for a mobile platform guidance system is disclosed. In embodiments, the architecture comprises a hierarchy of arbitration layers, each arbitration layer narrower in scope than the layer above (e.g., mission objective arbitrators, route arbitrators, path arbitrators). Each arbitration layer includes one or more objective-based arbitrators in communication with one or more applications or modes. Each arbitrator receives control input (e.g., from the pilot, from aircraft sensors) and control signals from the level above, selecting a mode to make active based on decision agents within the arbitrator layer which control mode priorities and sequencing (e.g., some flight objectives may involve multiple arbitrators and their subject applications coordinating in sequence).

  • Patent number: 11960693
    Abstract: A resistive touch sensor includes a base layer, a sensor top sheet positioned in spaced apart relation to a base layer, and a peripheral edge seal formed between the sensor top sheet and the base layer. The sensor further includes a first adhesive layer bonded on a peripheral edge portion to the sensor top sheet, and a second adhesive layer, inset relative to the peripheral edge seal, positioned between the first adhesive layer and the sensor top sheet. The second adhesive layer is bonded on one side to the first adhesive layer and an opposing side to the sensor top sheet corresponding to a portion of a touch active area. The second adhesive layer causes a planarity change in the sensor top sheet proximate the peripheral edge seal thereby increasing the usable area and improving uniformity of touch force across the sensor.

  • Patent number: 11960644
    Abstract: A system and method for inferring operator intent by detecting operator focus incorporates cameras positioned within a cockpit or control space of a vehicle and oriented at an operator of the vehicle. The cameras capture images of the operator in a control seat; the images are analyzed (either individually or sequentially) to determine a gaze and/or body pose of the operator (including, e.g., a position and orientation of the torso and limbs). By comparing the determined gaze and/or body pose to the positions and orientations of potential focus targets within the control space (e.g., windows, display units, and/or control panels that the operator may engage with visually and/or physically), the system predicts the most likely future focus target or targets: what the operator is most likely to visually and/or physically engage with next. Operator intent may be further analyzed to identify potentially abnormal or anomalous behavior.
