  • Patent number: 11929664
    Abstract: A multi-port converter includes a hybrid energy storage system (HESS) that provides a faster dynamic response to load changes than prior art systems, and enables either downsizing of the main energy storage system (ESS) to increase the life of the main ESS (e.g. energy battery), or retaining the same size ESS and increasing the range or life of the power source. The multi-port convertor can advantageously result in lower investment and maintenance costs, and can also advantageously provide a path for inputs to directly feed the load. All these benefits can be achieved while reducing the number of active switches and overall component count as compared to prior art systems.

  • Patent number: 11896120
    Abstract: An anchoring device for securing objects within a rack mount system using fasteners. The anchoring device has a base portion with flush and anchor faces, the anchor faces defining apertures. Hooks are provided for securing the anchoring device to the rack mount system. Each hook has a horizontal arm with base and distal ends, and a vertical arm with upper and lower ends. Each base end is coupled to the anchor face and each distal end is coupled to the upper end of one vertical arm. Hooks are receivable within openings in the rack mount system to secure the anchoring device. The apertures in the base portion align with the openings in the rack mount system when the anchoring device is secured to the rack mount system such that the object is securable to the rack mount system by engaging the fasteners with the apertures in the anchoring device.

  • Patent number: 11567039
    Abstract: Passive wireless sensors include an antenna. The antenna receives a combined signal. The combined signal includes a low frequency modulating signal modulated on a high frequency carrier wave. A demodulator receives the combined signal and extracts the modulating signal. A sensor receives the extracted modulating signal and produces an output signal with a time delay indicative of a property to be sensed. A modulator receives the output signal and the high frequency carrier wave and modulates the output signal onto the high frequency carrier wave to create a combined output signal broadcast by the antenna.

  • Patent number: 11429111
    Abstract: Disclosed are systems and methods of sensor fusion for exemplary use with robotic navigation control. Systems and methods include providing local estimates of a target location from a plurality of expert modules that process sensor data. The local estimates are weighted based upon a Mahalanobis distance from an expected estimated value and based upon a Euclidean distance between the local estimates. The local estimates are fused in a Bayesian fusion center based upon the weight given to each of the local estimates.
