  • Publication number: 20240142695
    Abstract: Improvements to gratings for use in waveguides and methods of producing them are described herein. Deep surface relief gratings (SRGs) may offer many advantages over conventional SRGs and Bragg gratings, an important one being a higher S-diffraction efficiency. In one embodiment, deep SRGs can be implemented as polymer surface relief gratings or evacuated Bragg gratings (EBGs). EBGs can be formed by first recording a holographic polymer dispersed liquid crystal (HPDLC) grating. Removing the liquid crystal from the cured grating provides a polymer surface relief grating. Polymer surface relief gratings have many applications including for use in waveguide-based displays.

  • Publication number: 20240125148
    Abstract: A cabinet lock for protecting merchandise within a merchandise display cabinet having an inner door and an outer door. The cabinet lock includes a strike plate affixed to the inner door and a lock housing affixed to the outer door such that the cabinet is in a locked configuration that prevents access to the merchandise when the lock housing is operably engaged to the strike plate. A programmable electronic key communicates a security code with the cabinet lock and transfers electrical power to the cabinet lock to operate a lock mechanism between the locked configuration and an unlocked configuration. An indicator is provided for indicating whether the cabinet lock is in the locked configuration or the unlocked configuration. The indicator includes a first segment and a second segment that can be energized to visually indicate the status of the cabinet lock.

  • Patent number: 11913970
    Abstract: A wireless motion detection system is provided which uses a sharp band-stop and low-pass filters to reject unwanted low and high frequency components of a signal in the CSI. A gap in the frequency domain is caused by taking the absolute value of the signal when using the absolute value of channel matrix H? for motion detection. A sharp band-stop (notch) filter is used to reject any unwanted signals that have significant components in this gap. A low-pass filter is used to reject all unwanted signal after the motion highest frequency.

    Abstract: Technologies for attestation techniques, systems, and methods are provided for determining patient movement and conditions. The patient's movement may be determined by passive indoor positioning technology using channel state information (CSI). Activity data from an activity database may be retrieved from a Wi-Fi access point located in proximity to a monitored space and analyzed to determine an activity trend of a patient in the monitored space. An electronic medical records database may be polled for one or more health events each associated with a set of health parameters. The activity data may be compared to the associated parameter sets of the health events to identify any matches. A notification may be sent to a designated device (e.g., of a caregiver) based on a match between the activity data or trends thereof with the parameter set of a health event.
