Patent number: 11942937Abstract: Pulse-generator-based reciprocal quantum logic (RQL) bias-level sensors are fabricated on an RQL integrated circuit (IC) to sample AC or DC bias values provided to operational RQL circuitry on the RQL IC. The bias-level sensors include pulse generators having strengthened or weakened bias taps (transformer couplings to RQL AC clock resonators or DC bias lines) as compared to bias taps of Josephson transmission lines in the operational RQL circuitry, or Josephson junctions (JJs) with larger or smaller critical currents as compared to JJs in the operational RQL circuitry. Pulse generators with weakened bias taps or larger JJs can have lower limits of their operational ranges placed near an optimal bias point at the centroid of the operating region of the operational RQL circuitry. The bias-level sensors can be staged by relative strength to indicate whether a provided bias value is an improvement when varied over a range.Type: GrantFiled: May 4, 2022Date of Patent: March 26, 2024Assignee: NORTHROP GRUMMAN SYSTEMS CORPORATIONInventors: Charles Ryan Wallace, Max E.

Patent number: 11933976Abstract: Systems and methods for tracking the position of one or more head-mounted display (HMD) system components of an HMD system. The HMD components may carry a plurality of angle sensitive detectors or other types of detectors. The HMD system may be operative to detect corrupted position tracking samples, allowing such samples to be ignored, thereby improving the position tracking process. Control circuitry causes light sources to emit light according a specified pattern, and receives sensor data from the plurality of detectors. Control circuitry may process the sensor data, for example using machine learning or other techniques, to track a position of one or more HMD components.Type: GrantFiled: September 27, 2022Date of Patent: March 19, 2024Assignee: Valve CorporationInventors: Evan Fletcher, Jeffrey Walter Mucha, Joshua Mark Hudman, Alan Yates, Gordon Wayne Stoll, Jeffrey George Leinbaugh, Charles Lohr

Patent number: 11919740Abstract: A reel based closure device includes a housing, a spool positioned within the interior region of the housing, a knob that is operably coupled with the spool and with the housing, and a rotation control component that is operably coupled with the knob. The knob is rotatable in a tightening direction to cause the spool to rotate within the housing and thereby wind the tension member about the spool. The knob is also rotatable in a loosening direction to cause the spool to rotate in an opposite direction within the housing and thereby unwind the tension member from about the spool. The rotation control component is configured to prevent accidental loosening of the tension member by inhibiting rotation of the knob in the loosening direction until a sufficient rotational force is exerted on the knob in the loosening direction.Type: GrantFiled: October 13, 2022Date of Patent: March 5, 2024Assignee: BOA Technology, Inc.Inventors: Randon George Kruse, Josef Duller, Charles Clay Corbett, Ryan Vogt

Publication number: 20230364330Abstract: A medical device for infusing medical substances has activation buttons accessible on the exterior of the device housing. Activation buttons and corresponding electrical switches within the housing are configured to prevent inadvertent activation of the buttons and therefore inadvertent operation of the switches to initiate a process such as medical substance delivery to the user. The device employs overlap of respective time traces initiated by activation of the activation buttons to determine whether activation is intended and valid. These time traces do not have to be initiated simultaneously or in any particular sequence. The activation buttons can be elastomeric overmolded buttons set within cutouts in the housing, and, when depressed, make physical contact with respective switches.Type: ApplicationFiled: July 25, 2023Publication date: November 16, 2023Applicant: Becton, Dickinson and CompanyInventors: Charles George HWANG, J.
