  • Patent number: 11075972
    Abstract: The disclosure is directed to systems and methods for local rendering of 3D models which are then accessed by remote computers. The advantage of the system is that extensive hardware needed for rendering complex 3D models is centralized and can be accessed by smaller remote computers without and special hardware or software installation. The system also provides enhanced security as model data can be restricted to a limited number of servers instead of stored on individual computers.

  • Publication number: 20210063509
    Abstract: The present disclosure generally relates to a Wheatstone bridge that has four resistors. Each resistor includes a plurality of TMR structures. Two resistors have identical TMR structures. The remaining two resistors also have identical TMR structures, though the TMR structures are different from the other two resistors. Additionally, the two resistors that have identical TMR structures each have an additional non-TMR resistor as compared to the remaining two resistors that have identical TMR structures. Therefore, the working bias field for the Wheatstone bridge is non-zero.

  • Publication number: 20200278445
    Abstract: This disclosure enables various technologies for determining space object attitude stabilities from radar cross-section statistics. In particular, such determinations can be made via employing various phased-array radars with various fields of views, which can monitor various space objects (e.g., satellites, space debris, rocket bodies, space stations) over various periods of time (e.g., minutes, hours, days, weeks, months) as the space objects come into the fields of views. For example, a technique for estimating attitude stability of low-Earth RSOs using RCS statistics from various radars (e.g., group of radars, phased-array radar network). Assuming a non-isotropic shape, an Earth-oriented RSO can have an elevation-angle dependent RCS when viewed from a ground-based radar. Therefore, an RSO attitude stability can be tested by looking for a difference in a median or mean RCS when the RSO is viewed at different elevation angles.

  • Patent number: 10725582
    Abstract: The invention relates to a processing system. The processing system includes a determination module configured to make a determination that a low ground mass condition associated with an input device exists in an initial combination signal obtained from a sensor module using initial sensor settings. Based on the determination, adjusted sensor settings are determined, and an adjusted combination signal is obtained, using the adjusted sensor settings and, using the adjusted combination signal, object information for one or more input objects in a sensing region of the input device is obtained. The sensor module is configured to generate, using a first sensor electrode, a second sensor electrode, and the adjusted sensor settings, the adjusted combination signal. The adjusted combination signal includes effects of a transcapacitive coupling between the first sensor electrode and the second sensor electrode and effects of an absolute capacitive coupling between the second sensor electrode and the input object.

  • Patent number: 10613682
    Abstract: Sensor circuitry is configured to perform, for a sensing frame, mutual capacitive sensing to obtain mutual capacitive measurements, and perform, for the sensing frame, first self-capacitive sensing to obtain first self-capacitive measurements, and perform second self-capacitive sensing to obtain a second self-capacitive measurements. Processing circuitry is connected to the sensor circuitry and is configured to detect an inconsistency between the mutual capacitive measurements and the first self-capacitive measurements, and halt, in response to detecting the inconsistency, a second sensing frame to trigger performing the second self-capacitive sensing. The second sensing frame is subsequent to the first sensing frame. The processing circuitry is further configured to determine intermittent interference using the first self-capacitive measurements and the second self-capacitive measurements.

  • Publication number: 20200082594
    Abstract: A system provides the ability to import large engineering 3D models from a primary 3D rendering software into a secondary 3D rendering software that does not have the tools of the resources to render the larger 3D model on its own. The system uses a plugin to combine 3D data from the two software sources, and then return the combined 3D data to the secondary 3D rendering software. Components of the system can be remote or cloud based, and the system facilitates video streaming of 3D rendered models that can be manipulated on any computer capable of supporting a video stream.

  • Patent number: 10444922
    Abstract: Sensor electrodes are coupled, in a first configuration, to input channels of a processing system. The sensor electrodes are used to acquire a measurement of current. In a second configuration that is different from the first configuration, the sensor electrodes are coupled to the input channels. The sensor electrodes in the second configuration are used to acquire a capacitive resulting signal. Positional information is determined using the current measurement and the capacitive resulting signal.
