Publication number: 20240125824Abstract: Systems and methods are provided for monitoring the effects of conductive dust deposits that compromise the ability of a trip unit to accurately detect AC current in a circuit interrupter. When a Rogowski coil is used as a current sensor in the circuit interrupter and the trip unit processes the output of the Rogowski coil using a printed circuit board assembly (PCBA) processing circuit, the DC component of the processing circuit output signal can be analyzed to determine whether any conductive dust has formed unintended electrical pathways on the PCBA and compromised the ability of the PCBA to accurately measure AC current in the circuit interrupter. It can be determined that such unintended electrical pathways have formed when the DC component of the processing circuit output either exceeds a predetermined threshold or has increased by a significant amount after opening of the separable contacts.Type: ApplicationFiled: October 13, 2022Publication date: April 18, 2024Applicant: EATON INTELLIGENT POWER LIMITEDInventors: Theodore J.

Publication number: 20240028117Abstract: Eye and hand tracking systems in head-mounted display (HMD) devices are arranged with lensless camera systems using optical masks as encoding elements that apply convolutions to optical images of body parts (e.g., eyes or hands) of HMD device users. The convolved body images are scrambled or coded representations that are captured by a sensor in the system, but are not human-recognizable. A machine learning system such as a neural network is configured to extract body features directly from the coded representation without performance of deconvolutions conventionally utilized to reconstruct the original body images in human-recognizable form. The extracted body features are utilized by the respective eye or hand tracking systems to output relevant tracking data for the user's eyes or hands which may be utilized by the HMD device to support various applications and user experiences. The lensless camera and machine learning system are jointly optimizable on an end-to-end basis.Type: ApplicationFiled: October 3, 2023Publication date: January 25, 2024Inventors: Curtis Alan TESDAHL, Benjamin Eliot LUNDELL, David ROHN, Dmitry RESHIDKO, Dmitriy CHURIN, Kevin James MATHERSON, Sayyed Jaffar Ali RAZA

Patent number: 10727012Abstract: A molded case circuit interrupter advantageously employs a circuitry component that is situated adjacent a rear exterior surface of the molded case of the molded case circuit interrupter. Previous circuit interrupters have sometimes employed a non-conductive backsheet of a nominal thickness of 0.062 inches that was adhered to the rear surface of the molded case circuit interrupter in order to electrically isolate screws, posts, and the like that were mounted to and that were exposed on the rear portion of a molded case thereof. The disclosed and claimed concept provides a circuitry component in place of or in addition to the back sheet, with the circuitry component including flexible ribbons having electrical conductors that extend through holes formed in the molded case and that are electrically connected with electronic components that are situated within the interior of the molded case.Type: GrantFiled: September 14, 2018Date of Patent: July 28, 2020Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Richard Paul Malingowski, Theodore J.
