Patent number: 11962293Abstract: A passive sensor for detecting the operation of a light source includes a photosensor which, when illuminated by the light source, delivers a voltage to a field effect transistor (FET) which can switch a circuit to control a device at a remote location. The FET transitions rapidly between very low resistance (short circuit) and very high resistance (open circuit), allowing a binary indication to be given in the circuit. The circuit can be used to charge an electrical storage device to allow later download of recent status of the lamp by detecting the charge stored in the device.Type: GrantFiled: March 18, 2019Date of Patent: April 16, 2024Assignee: British Telecommunications Public Limited CompanyInventors: Mohammad Zoualfaghari, Michael Fisher, Ian Neild, Michael Williamson

Patent number: 11935574Abstract: A memory cell comprises a capacitor comprising a first capacitor electrode having laterally-spaced walls, a second capacitor electrode comprising a portion above the first capacitor electrode, and capacitor insulator material between the second capacitor electrode and the first capacitor electrode. The capacitor comprises an intrinsic current leakage path from one of the first and second capacitor electrodes to the other through the capacitor insulator material. A parallel current leakage path is between the second capacitor electrode and the first capacitor electrode. The parallel current leakage path is circuit-parallel with the intrinsic current leakage path, of lower total resistance than the intrinsic current leakage path, and comprises leaker material that is everywhere laterally-outward of laterally-innermost surfaces of the laterally-spaced walls of the first capacitor electrode. Other embodiments, including methods, are disclosed.Type: GrantFiled: October 7, 2021Date of Patent: March 19, 2024Assignee: Micron Technology, Inc.Inventors: Michael Mutch, Ashonita A.

Publication number: 20230414291Abstract: Systems, computer-implemented methods, and computer program products for planning of a cutting boundary for removal of a diseased region of an anatomy, such as a bone tumor. A cutting surface is placed relative to the diseased region in a virtual model. An optimization algorithm specifies an optimization criterion that minimizes an amount of healthy region to be removed by the cutting surface and initializes candidate solutions to influence characteristics of the cutting surface. The optimization algorithm identifies a candidate solution that satisfies the optimization criterion and modifies characteristics of the cutting surface based on the identified candidate solution. The cutting boundary is defined relative to diseased region in the virtual model based on the modified cutting surface. The cutting boundary can be registered to the anatomy for constraining operation of a surgical tool in response to interaction of the surgical tool with the registered cutting boundary.Type: ApplicationFiled: September 14, 2023Publication date: December 28, 2023Applicant: Stryker Australia PTY LTDInventors: Dave Gibson Hill, Tom Michael Williamson, Chow Yin Lai

Publication number: 20220286427Abstract: Methods and related systems are presented that relate to automatically avoiding address conflicts when establishing a secure communications link over a public network between a local computer, associated with a local network, and a remote device, located outside the local network. Local network addresses on the local network reserved for use, and a block of local network addresses that do not conflict with the reserved local network addresses, are identified. At least one local network address is selected from the block and assigned as an address of the local device for use in communicating with the remote device securely over the public network. Communication is facilitated with the remote device using the network driver based on the assigned at least one local network address.Type: ApplicationFiled: March 25, 2022Publication date: September 8, 2022Applicant: VirnetX, Inc.Inventors: Robert Dunham Short, III, Michael Williamson, Victor Larson

Patent number: 11245692Abstract: Systems and methods are provided for establishing a secure communication link between a first client and a second client. One exemplary computer-implemented method for establishing a secure communication link between a first client and a second client includes accessing, from a storage, identification information of a user of the first client. The method further includes receiving a Domain Name Service (DNS) request from the first client requesting a secure network address corresponding to a secure domain name associated with the second client. The method further includes authenticating the user based on the user identification information. The method also includes transmitting the secure computer network address in response to the DNS request based on a determination that the user has been authenticated. A secure communication link between the first client and the second client is established based on the secure computer network address.Type: GrantFiled: March 12, 2019Date of Patent: February 8, 2022Assignee: VirnetX, Inc.Inventors: Robert Dunham Short, III, Nathaniel Jackson Short, Michael Williamson

Patent number: 11090675Abstract: A sprinkler height adjustment mechanism is described that can be used to increase the height of a top cover and a top of the riser relative to the sprinkler body. The height adjustment mechanism is particularly useful for sprinklers with compartments having removable tops, however, a similar design can also be adapted for sprinklers without compartments (e.g., components that connect to a sprinkler flange or the sprinkler riser).Type: GrantFiled: March 8, 2019Date of Patent: August 17, 2021Assignee: The Toro CompanyInventors: Steven C.

Patent number: 11049409Abstract: Systems and methods are provided for automatically scoring a response and statistically revaluating whether it can be considered as aberrant. In one embodiment, a constructed response is evaluated via a pre-screening stage and a post-hoc screening stage. The pre-screening stage attempts to determine whether the constructed response is aberrant based on a variety of aberration metrics and criteria. If the constructed response is deemed not to be aberrant, then the post-hoc screening stage attempts to predict a discrepancy between what score an automated scoring system would assigned and what score a human rater would assign to the response. If the discrepancy is sufficiently low, then the constructed response may be scored by an automated scoring engine. On the other hand, if the constructed response failed to pass either of the two stages, then a flag may be raised to indicate that additional human review may be needed.Type: GrantFiled: December 18, 2015Date of Patent: June 29, 2021Assignee: Educational Testing ServiceInventors: Mo Zhang, Jing Chen, Andre Alexander Rupp, David Michael Williamson
