  • Patent number: 11922733
    Abstract: A method of enrolling a user at a biometric lockset is described. The method includes receiving user access information from a mobile device of an administrative user of the biometric lockset. The user access information indicates to the biometric lockset to enter an enrollment mode in which a user identity is associated with fingerprint data in a user entry within a memory of the biometric lockset. A plurality of different light codes are displayed on the lockset, each one of the plurality of light codes representative of a different state of fingerprint data capture. A message is transmitted to the mobile device, and corresponds to the light code displayed at the lockset. The completed fingerprint data is stored in association with the user identity of the user in the user entry.

  • Publication number: 20240013734
    Abstract: This application is directed to a method for correct temperature measurement. An electronic device includes a temperature sensor that measures an ambient temperature of an environment and a display that is driven by a display driver. The electronic device determines a brightness setting of the display, estimates a display driver current based on the brightness setting, estimates a driver efficiency of the display driver based on the display driver current, and combines a predetermined display driver voltage, the display driver current, and the driver efficiency to determine a power consumption of the display driver. An ambient temperature correction is determined in accordance with the determined power consumption of the display driver, and the measured ambient temperature is thereby corrected using the ambient temperature correction. In some implementations, a power consumption of a distinct heat-generating electronic component is also monitored for adjusting the ambient temperature correction.

  • Publication number: 20220176070
    Abstract: A surgical instrument may include a multi-lumen catheter configured to be inserted within the tissue. The multi-lumen catheter may include a first lumen that may enable a flow of a fluid, a second lumen that may receive a navigation probe that may facilitate an ability to locate the region of interest within the tissue, and an expandable membrane that may be situated toward a distal end of the first lumen to form an expandable cavity. The expandable cavity may be configured to expand or contract based on the flow of the fluid through the first lumen. The surgical instrument may include a fluid line, coupled to the first lumen, that may supply the fluid to the first lumen to enable the expandable cavity to expand or withdraw the fluid from the first lumen to enable the expandable cavity to contract.

  • Patent number: 9794256
    Abstract: A cloud-based platform (e.g., cloud-based collaboration and/or storage platform/service) is described that provides advanced control tools for administrators of an enterprise account. The advanced control tools permit the administrator to set mobile security settings for mobile devices running applications that allow a user to access enterprise data in the cloud-based platform; activity notification archiving; support for multiple email domains; automation processes; and policies. The settings selected by the administrator are applied enterprise-wide within the cloud-based platform.
