  • Publication number: 20220025218
    Abstract: An antimicrobial metallized thin film is provided that can be quickly and easily attached to surfaces of objects. This film includes a polymer substrate onto which a metallized layer is formed. The metallized layer comprises an exposed antimicrobial metal physical contact surface. Ions from this physical contact surface destroy the viral coating and ribonucleic acid of contacting viruses rendering the viruses inactive and noninfectious. The film can be attached via an adhesive layer disposed between and in contact with the polymer substrate and the communal surface. This arrangement allows the film to economically refurbish communal surfaces with a film overlay rather than completely replacing communal surfaces with antimicrobial materials. The film mitigates the likelihood of viruses such as coronaviruses, noroviruses, rhinoviruses, and the like from spreading due to contact with the refurbished communal surfaces.

  • Patent number: 11228203
    Abstract: A power converter with AFC (Automatic AC Feed Control) implements zero voltage switching when switching from a first input power supply to a second input power supply. The power converter with AFC includes a relay switchover circuit and control circuitry for selectively providing power to a connected power converter. The control circuitry uses sensed amplitude and phase values for the two input power supplies for determining when the first input power supply is lost and selectively connecting the second input power supply according to precise timing control to minimize component stress.

    Abstract: Embodiments provide systems and methods for providing a dynamically variable focal plane in a waveguide-based display. Generally speaking, embodiments described herein provide an optical system that allows variable control of the focal length of the image emerging from the display engine into the waveguide. This can be a dynamic system that is controlled based upon the content being projected on the display. For a stereoscopic system, individual control of each eye can be provided. More specifically, embodiments comprise an electrically tunable lens element interposed between the output of the projection engine and the optical waveguide and a control unit to dynamically the tunable lens element to vary the focal length of the images provided to the waveguide display.

  • Patent number: 11185631
    Abstract: A device and method for measuring an IV pump infusion system flow comprises a fluid source configured to store medicinal fluid and a weight sensing mechanism comprising a weight sensor and microprocessor. The weight sensing mechanism is configured to detect the weight of the fluid source as the medicinal fluid leaves the fluid source. The device in the infusion system administers medicinal fluid using a set flow rate for the IV pump input into the control unit prior to infusion, measures the change in mass of the fluid source containing medicinal fluid as fluid exits the source, calculates the flow rate based on the change in mass over time, compares the calculations with a set flow rate, and adjusts the IV pump and flow rate based on the compared deviations, for improved delivery accuracy. This configuration may also prevent patient harm and medicine waste.

  • Patent number: 11174665
    Abstract: A method and system for a camera based hands free power liftgate is described herein. The system may power on following a key approach and/or the doors unlocking and then initialize. If there is an approach detected, the lights may be activated and the gesture detection feature of the system may then determine whether a gesture was detected. If a gesture was detected, the liftgate may then be activated. If no gesture was detected, the lights may be activated. For example, if there is a key approach, the system may power and initialize. The system may then determine whether an approach is detected. If an approach is detected, lights of the vehicle may activate and a determination whether a gesture is detected is made. If a gesture is detected, a liftgate of the vehicle may be activated.
