  • Patent number: 11059568
    Abstract: A control system having a variable operator interface (VOI) is disclosed, and includes one or more processors and a memory coupled to the processors. The memory stores program code causing the control system to detect an existence and first direction of an operator control input to one or more active inceptors being backdriven from an operator on inceptor detector (OID). The control system is caused to compare the first direction of the operator control input with a second direction of one or more zero-force detent rates to determine a variance and interprets the operator control input as inadvertent based on the variance. In response to interpreting the operator control input as inadvertent, the control system is caused to limit the operator control input to reduce or substantially eliminate movement of the machine caused by inadvertent input by modifying the operator control input based on one or more command modifiers.

  • Patent number: 11023241
    Abstract: Systems and methods selectively bypass address-generation hardware in processor instruction pipelines. In an embodiment, a processor includes an address-generation stage and an address-generation-bypass-determination unit (ABDU). The ABDU receives a load/store instruction. If an effective address for the load/store instruction is not known at the ABDU, the ABDU routes the load/store instruction via the address-generation stage of the processor. If, however, the effective address of the load/store instruction is known at the ABDU, the ABDU routes the load/store instruction to bypass the address-generation stage of the processor.

  • Patent number: 11019755
    Abstract: Energy efficient control of cooling system cooling of an electronic system is provided based, in part, on weighted cooling effectiveness of the components. The control includes automatically determining speed control settings for multiple adjustable cooling components of the cooling system. The automatically determining is based, at least in part, on weighted cooling effectiveness of the components of the cooling system, and the determining operates to limit power consumption of at least the cooling system, while ensuring that a target temperature associated with at least one of the cooling system or the electronic system is within a desired range by provisioning, based on the weighted cooling effectiveness, a desired target temperature change among the multiple adjustable cooling components of the cooling system. The provisioning includes provisioning applied power to the multiple adjustable cooling components via, at least in part, the determined control settings.

  • Patent number: 10966022
    Abstract: An augmented reality environment allows interaction between virtual and real objects. Multiple microphone arrays of different physical sizes are used to acquire signals for spatial tracking of one or more sound sources within the environment. A first array with a larger size may be used to track an object beyond a threshold distance, while a second array having a size smaller than the first may be used to track the object up to the threshold distance. By selecting different sized arrays, accuracy of the spatial location is improved.

  • Publication number: 20210061444
    Abstract: A flight control system having a plurality of dual mode operator control inputs is disclosed and includes a plurality of active parallel actuators, one or more processors, and memory coupled to the one or more processors. The memory stores data comprising a database and program code that, when executed by the one or more processors, causes the flight control system to receive a signal indicating an airspeed of the compound aircraft and select between rotary and fixed wing modes of operation based on the airspeed. In response to selecting a mode of operation, the flight control system sends either a rotary or a fixed wing force feel profile to the plurality of active parallel actuators, where the force feel profile defines the respective detent force gradient, where the fixed wing detent force gradient is at least about two times greater than a rotary wing detent force gradient.

  • Patent number: 10916796
    Abstract: Energy storage devices, battery cells, and batteries may include a first current collector having an anode active material disposed along a first surface of the first current collector. The cells may include a plurality of first electrodes positioned along a second surface of the first current collector opposite the first surface. The plurality of first electrodes may be characterized by a first orientation. The cells may include a second current collector having a cathode active material disposed along a first surface of the second current collector. The cells may include a separator positioned between the anode active material and the cathode active material. The cells may also include a plurality of second electrodes positioned along a second surface of the second current collector opposite the first surface. The plurality of second electrodes may be characterized by a second orientation substantially orthogonal to the first orientation.

  • Patent number: 10908560
    Abstract: A control system for a machine having variable rate damping based control (VRDC) is disclosed, and includes one or more processors and a memory coupled to the processors storing data comprising a database and program code that, when executed by the processors, causes the control system to receive an inceptor position from one or more active inceptors and calculate an operator command based on at least the inceptor position. The control system is caused to determine an amplitude of the operator command. The control system is caused to determine a variable gain based on the amplitude of the operator command and determines an actuation command based on the variable gain. The control system sends the inline actuators the actuation command. The inline actuators actuate into a total actuator position to variably damp movement of the machine as a function of the magnitude of the operator command.

  • Patent number: 10833900
    Abstract: A receiver signal is sampled at a sampling rate equivalent to a chip rate at which chips of a known signal are timed. The resulting receiver signal samples are segmented into receiver signal segments, which are filtered by respective matched filters that are matched to known signal segments segmented from the known signal. Indexes are assigned to elements of the resulting filter response sequences to define an array thereof. Frequency transforms are computed of elements of the filter response sequences in respective columns of the array. Indexes are assigned to elements of the resulting frequency response sequences to define another array thereof. Channel effects imparted on a radio signal are jointly estimated from characteristics of the other array at which at least one local maximum is located.
