  • Publication number: 20250073377
    Abstract: A biocompatible surgical article is provided for cutting biological tissue or implantation in contact therewith. The surgical article has a composition of tungsten carbide—nickel with a percentage of additional metal carbides present. A typical composition in total weight percentages is WC 85 to 95%, Cr3C2, Mo2C, VC each alone or in combination being present from 0 to 2%, and Ni constituting the remainder. The composition is formed to have an mean grain size of between 200 and 800 nm with a particle dispersion index (PdI) corresponding to (the square of the standard deviation)/(mean grain size) of between 0 and 0.6, and in some embodiments between 0.02 and 0.2.

  • Patent number: 12238100
    Abstract: A controlled-environment facility resident communication and/or media device master control employs a controlled-environment facility vendor datacenter, a centralized investigative data aggregation and analysis system, or the like, to provide a controlled-environment facility management portal to a controlled-environment facility administrator, presenting an option to disable controlled-environment facility resident communication and/or media devices operating in a controlled-environment facility. The controlled-environment facility vendor datacenter, or the like, disables access to controlled-environment facility resident communication and/or media devices operating in the controlled-environment facility, in response to selection of the option to disable devices operating in the facility, sends a message to devices operating in the facility to disable all application programs on a respective device, and disable access to devices operating in the controlled-environment facility.

  • Publication number: 20240125546
    Abstract: The present invention is directed to a method, device and system to efficiently liquefy and isolate a gas from a gaseous mixture. In an embodiment of the present invention, separation of gasses from the atmosphere can be carried out using a cooled surface to separate the gasses from the atmosphere. In an alternative embodiment of the present invention, removal of CO2 from the atmosphere can be carried out by using the method, device and system to efficiently cryogenically separate CO2 from air and capture the CO2 from a gaseous mixture using a surface and release the ‘CO2 lean air’ into the atmosphere and store the captured liquefied CO2.

  • Patent number: 11829427
    Abstract: Embodiments are directed to a database configured to store digital versions of physical or electronic items received at a controlled-environment facility. Each of the digital versions associated with a unique identifier. A digital network portal is configured to provide remote access to the database. A production system is configured to create physical or electronic copies of selected ones of the stored digital versions. The physical or electronic copy comprises an image of the original physical or electronic item and a two-dimensional barcode. The two-dimensional barcode comprises a network address for the digital network portal and the unique identifier. The two-dimensional barcode may comprise a Quick Response (QR) code.

  • Patent number: 11166160
    Abstract: A system for contraband device identification and alerting is disclosed. The system comprises a wireless signal detection system configured to identify signals from an unauthorized wireless device, and an alert module configured to generate notifications when an unauthorized wireless device is detected. The unauthorized wireless device is operating within a designated or controlled area. The designated area may overlap a controlled-environment facility and the wireless device is contraband within the controlled-environment facility. The alerting system may include a speaker, wherein the notifications comprise an audible message broadcast via the speaker. The alerting system may include one or more lights, wherein the notifications comprise illuminating the light. The notifications may also comprise one or more of a call, email, audible or visual alert, vibration and text that are sent to a designated individual.

  • Publication number: 20210279360
    Abstract: Disclosed herein is a consent management (CM) technology that facilitates the tracking of consented data transactions with customer-consent data records by an agency. A consented data transaction includes an action requested to or actually performed on or with a customer-consent data record of a particular customer of the agency. The customer-consent data record contains sensitive personal information (SPI) of and/or about the particular customer. With this technology, the agency's CM system may provide evidence of all consented data transactions with the customer-consent data record to, for example, government regulators and to the customer herself.

  • Patent number: 10690240
    Abstract: A computer system (e.g., an on-board vehicle computer system) creates or updates a mapping of transmission gears and respective driveline ratios during operation of the vehicle. The system obtains a current engine speed and vehicle speed and calculates a current driveline ratio for the vehicle based on the current engine speed and vehicle speed. If the driveline is engaged, the system updates the mapping based at least in part on the current driveline ratio. Performing the update may include adding a new transmission gear or updating an existing transmission gear in the mapping, or removing a duplicate transmission gear from the mapping. Applications include cruise control, predictive cruise control, predictive shifting, and selecting a gear for a specific purpose (e.g., for descending a hill).
