  • Publication number: 20240074158
    Abstract: A variety of applications can include an apparatus having a memory device in which, during fabrication of the memory device, processing a dielectric isolation region about an active area of a memory cell is controlled to provide enhanced electric isolation of a data line contact to the memory cell with respect to a cell contact to the memory cell. A portion of the dielectric isolation region can be recessed, creating a corner between the dielectric isolation region and a conductive region, where the conductive region is material for the active area. The corner can be filled with a dielectric material and the data line contact can be formed contacting the dielectric material and coupled to the conductive region. The cell contact can be formed to the memory cell contacting the dielectric material such that the dielectric material is between the cell contact and the data line contact.

  • Publication number: 20230213232
    Abstract: Methods, systems, and devices for an interactive environmental control system are described. In some examples, operating temperatures for individual zones of an environment may be determined based on inputs received from occupants of the respective zones. For example, a building may be separated into zones, and environmental conditions at each zone may be monitored and adjusted independently. Each occupant of a zone may update their environmental preference and the system may utilize the user inputs to set and adjust an operating temperature for the respective zone based on the occupants' preferences. In some examples, the system may implement machine learning techniques to predict and set operating conditions for the zones based on inputs, such as a history of inputs, from building occupants (e.g., from occupants of a respective zone).

  • Patent number: 11398146
    Abstract: Methods, systems, and non-transitory machine-readable media associated with an emergency assistance response are described. A system for an emergency assistance response can include a non-transitory machine-readable medium comprising a processing resource in communication with a memory resource having instructions executable to receive signaling associated with monitored health data. The instructions can be executable to track the received signaling, identify, output data representative of abnormal health data based on the tracked received signaling, and transmit the output data to a wearable device. The wearable device can receive the output data representative of the abnormal health data, provide a prompt via a user interface to a wearer of the wearable device associated with the abnormal health data, determine a response to the abnormal health data based on a reply or non-reply from the wearer via the user interface, and transmit the response to the processing resource.
