Patent number: 12385660Abstract: A physics model of a building is linearized around an operating point. Measurements received from sensors define a system state of the HVAC system. The linearized physics model is used as an equality constraint for a model predictive controller that determines a next control input to the HVAC system based on the system state by solving an optimization problem for a time horizon of size N. A constraint matrix H of the equality constraint is decomposed into factors of U and V matrices such that UUT and VT V are both diagonal matrices. An objective function of the model predictive controller is optimized by iteratively solving a linear system of equations that includes inverses of UUT and VT V to determining a sequence of inputs for a horizon of the model predictive controller. A first input of the sequence of inputs to is used to control the HVAC system.Type: GrantFiled: December 28, 2022Date of Patent: August 12, 2025Assignee: Xerox CorporationInventors: Muhammad Adil, Raman Goyal, Saman Mostafavi, Subhashis Hazarika, David E.

Patent number: 12373001Abstract: The present disclosure discloses a method and a system for securing a user interface (UI) panel of a multi-function device. The method includes activating a retraction assembly, based on one or more retraction triggering conditions. Once the retraction assembly is activated, multiple components of the retraction assembly start functioning. At first, the UI panel is moved to a first position. Next, the UI panel is moved from the first position to a second position. Then, the UI panel in the second position is retracted into the multi-function device to secure the UI panel inside the multi-function device. This way, the UI panel is secured inside the multi-function device. Later, the retracted UI panel may be moved out of the multi-function device. To move the UI panel outside the multi-function device, the retraction assembly is activated again based on the one or more protraction triggering conditions.Type: GrantFiled: February 16, 2022Date of Patent: July 29, 2025Assignee: Xerox CorporationInventors: Srinivasarao Bindana, Prasanth Kalaiselvan

Patent number: 12367656Abstract: A system determines an input video and a first annotated image from the input video which identifies an object of interest. The system initiates a tracker based on the first annotated image and the input video. The tracker generates, based on the first annotated image and the input video, information including: a sliding window for false positives; a first set of unlabeled images from the input video; and at least two images with corresponding labeled states. A semi-supervised classifier classifies, based on the information, the first set of unlabeled images from the input video. If a first unlabeled image is classified as a false positive, the system reinitiates the tracker based on a second annotated image occurring in a frame prior to a frame with the false positive. The system generates an output video comprising the input video displayed with tracking on the object of interest.Type: GrantFiled: September 8, 2022Date of Patent: July 22, 2025Assignee: Xerox CorporationInventors: Matthew A.
