  • Patent number: 10931315
    Abstract: A system and method for detecting an angle of arrival (AoA) of incident waves are disclosed. An array of wave sensors each transduce incident waves into an electrical signal, which is then provided an additional phase shift that varies between sensors. Electrical signals from adjacent wave sensors, having different phase shifts, are coupled via a phase detector to classify the incident waves into “zero” and “one” AoA regions for that sensor pair. The outputs from many such phase detectors are combined to divide the space facing the array into many subregions, each subregion being associated with a unique codeword. Incident waves cause detection of codewords, that are decoded according to error detection and correction techniques, such as selecting, from a list, the codeword having a minimum Hamming distance to a received codeword. The decoder then outputs data indicating an AoA subregion associated with the decoded codeword.

  • Patent number: 10931241
    Abstract: An apparatus includes at least one processing device configured to obtain samples of an input signal to be amplified and, in real-time, pre-distort at least some of the samples using pre-distortion values from at least one lookup table. The pre-distorted samples are to be converted into an analog signal that is amplified by at least one power amplifier. The pre-distortion values at least partially compensate for a non-linear operation of the at least one power amplifier. The at least one processing device is also configured to compare an output signal generated by the at least one power amplifier to an expected signal to identify errors between the output and expected signals. The at least one processing device is further configured to update one or more pre-distortion values in the at least one lookup table based on the identified errors.

  • Patent number: 10927987
    Abstract: Ducting and/or duct couplings can be formed from shape memory polymer material, with the material for example being additively manufactured. The use of shape memory polymer material for one or more of the duct portions may allow for easier installation of the ducting, for example allowing the ducting to be warped and/or bent to fit into or through places that are hard to reach or hard to maneuver through, with the ducting then heated to cause it to return to a predetermined memory shape. The coupling of duct portions together may be accomplished by the duct portions including a shape memory polymer material, with for example ends of the duct portions fitted together, and then heated to use a shape memory property of the material to effect coupling. Heating of the shape memory polymer material also softens the material, allowing it to move to a previously set shape.

  • Patent number: 10929542
    Abstract: Methods, systems, and computer-readable mediums for detection of policy violations in an unmodified binary in a virtual environment include receiving the unmodified binary in an executable and linkable format (ELF). The unmodified binary is executed, via an emulator, within the virtual environment. The executing includes determining, by an instruction set emulator, a symbol that is referenced during the executing of the unmodified binary. The symbol, a current state, and a global state is sent to a software policy engine. The software policy engine determines an assertion associated with the symbol. The assertion verifies a policy is enforced. A previous state is updated based on the symbol. The assertion is executed based on the current state, the previous state, and the global state. The assertion is determined to have failed based on the executing the assertion. A warning is logged indicating the failed assertion.

A virtual machine monitor (VMM) can provide a kernel application program interface (API) that can be utilized to access and instrument an MSR. A method may include receiving, by the VMM, an MSR instrumentation command that identifies an MSR to instrument and causing instrumentation of the MSR identified in the MSR instrumentation command. Instrumentation of the identified MSR can be caused by configuring or manipulating a virtual machine control structure (VMCS) of a guest virtual machine (VM). The MSR instrumentation command may be an MSR instrumentation request command, an MSR remove request command, an MSR value set request command, or an MSR value fetch request command. In some cases, the VMM may be a Type-I hypervisor.

  • Patent number: 10924020
    Abstract: The present invention provides a prestart control circuit that measures a reflected voltage on the primary side of a switching power converter. The prestart control circuit pulses the synchronous rectifier switch OPEN and CLOSED, which allows a measurement of the reflected voltage on the primary side of the switching power converter. The reflected voltage is proportionate to the output voltage of the switching power converter. The prestart control circuit uses the reflected voltage to establish the initial duty cycle of the switching power converter. The switching power converter may be any converter that includes a synchronous rectifier, such as a flyback converter or a forward converter, in a single-ended, double-ended and/or multi-phased configuration.

  • Patent number: 10922446
    Abstract: A computational accelerator for determination of linkages across disparate works in a model-based system engineering (MBSE) regime accesses textual content of MBSE works and performs preprocessing of each MBSE work to produce a preprocessed data structures representing the MBSE works. The preprocessing gatherings significant terms from each MBSE work, and delineates the textual content of each MBSE work into segments corresponding to separately identifiable textual statements. Segment-wise comparison between segment pairings of the preprocessed data structures corresponding to different MBSE works is performed to produce a set of segment-wise comparison results based on terms common to each segment pairing, and statement-wise linkages between statements of the MBSE works are determined based on the set of segment-wise comparison results.
