Publication number: 20260142963Abstract: An authentication system includes a medical device, and a certificate bridge device configured to receive a request from the medical device. The certificate bridge device generates an endpoint request that includes the request from the medical device and facility credentials of a facility where the medical device is deployed. The certificate bridge device sends the endpoint request to a certificate authority, receives a signed copy of the request from the certificate authority, and sends the signed copy of the request to the medical device.Type: ApplicationFiled: November 14, 2025Publication date: May 21, 2026Inventors: Thomas Henry Briggs, Avinash Ashok Kank, Steven D. Morrow, Derek Strassle

Publication number: 20240201021Abstract: A method of determining a temperature of a patient includes measuring a first temperature of the patient with a temperature device, and measuring a second temperature of an environment with the temperature device. The method includes determining if a change in the ambient temperature exceeds a threshold. If the change does exceed the threshold, the method also includes applying a correction factor to the first temperature of the patient to account for the change in ambient temperature.Type: ApplicationFiled: December 20, 2023Publication date: June 20, 2024Inventors: John A. Lane, Scott A. Martin, Joseph Tari, Derek Strassle

Patent number: 11679962Abstract: A switch assembly for a lift unit includes a switch, an emergency stop device, and a reset actuator. The switch is arranged to move between a closed position, wherein the switch electrically couples a lift motor of the lift unit to an energy source, and an open position, wherein the switch electrically decouples the lift motor from the energy source. The emergency stop device is coupled to the switch and arranged to move the switch from the closed position to the open position. The reset actuator is coupled to the switch and arranged to move the switch from the open position to the closed position, wherein the reset actuator is controllable to move the switch from the open position to the closed position.Type: GrantFiled: June 2, 2020Date of Patent: June 20, 2023Assignee: Liko Research & Development ABInventors: Derek Strassle, Joseph Blackmon, Sravan Mamidi, Ka Wing Calvin Peer

Patent number: 11471349Abstract: A patient lift system includes a motor and a drum. The drum is operably coupled to the motor. The drum can be selectively driven to rotate by the motor. A housing surrounds at least the motor and the drum. A load-bearing member is provided that includes a first end and a second end. The first end of the load-bearing member can be operably coupled to at least one of the housing and the drum. The second end of the load-bearing member can be operably coupled to a patient support assembly. An electrically conductive member can be positioned within the load-bearing member. A user interface is configured to actuate the patient support assembly in vertical and horizontal directions.Type: GrantFiled: September 10, 2019Date of Patent: October 18, 2022Assignee: LIKO Research & Development ABInventors: Kayla Stevens, Derek Strassle

Patent number: 11344462Abstract: A person lifting apparatus includes a first lifting strap feeding device including a first drum and a first lifting strap wound on the first drum. A second lifting strap feeding device includes a second drum and a second lifting strap wound on the second drum. A controller is communicatively coupled to the first lifting strap feeding device and to the second lifting strap feeding device. The controller includes logic that controls operation of the first lifting strap feeding device and the second lifting strap feeding device based on a comparison of current draws of the first lifting strap feeding device and the second lifting strap feeding device.Type: GrantFiled: September 19, 2019Date of Patent: May 31, 2022Assignee: Liko Research & Development ABInventors: Joseph Tari, Derek Strassle

Publication number: 20200168308Abstract: Rail-mounted lift systems, systems comprising the same, and kits of parts for retrofitting rail-mounted lift systems are disclosed. A lift system includes a rail having a carriage support channel formed therein, a carriage slidably disposed in the carriage support channel for relative movement to the rail, a lift unit coupled to the carriage, the lift unit having a motor that extends and retracts a lifting strap, and a locating system having a first component and a second component separate from the first component. One of the first and second components is a transmitter providing a code that corresponds to a predetermined location and the other is a receiver detecting the code when the first and second components are moved in proximity to one another due to movement of the carriage along the rail.Type: ApplicationFiled: November 15, 2019Publication date: May 28, 2020Applicant: LIKO RESEARCH & DEVELOPMENT ABInventors: James Ledwith, Melissa Stancato, Svetlana Rud, Jacqueline Berkebile, Saumil Aggarwal, Frederick Collin Davidson, Abidemi Ajayi, Joseph Tari, Derek Strassle

Publication number: 20200085657Abstract: A method of determining a lifting event of a person lifting apparatus is provided. The method includes receiving one or more of (i) current load information from a current measuring device that is indicative of current drawn by an actuator operatively connected to a lifting strap of the person lifting apparatus; (ii) strap position information from a position sensor that is indicative of a paid out length of the lifting strap of the person lifting apparatus; and (iii) weight information from a weight sensor that is indicative of a load supported by the lifting strap of the person lifting apparatus. A computing device comprising a processor using logic is used to identify at least one of a raising event, a repositioning event and a lowering event based on the one or more of the current load information, strap position information and weight information.Type: ApplicationFiled: September 19, 2019Publication date: March 19, 2020Applicant: Liko Research & Development ABInventors: Neal Wiggermann, Jackie Berkebile, Derek Strassle, Melissa Stancato, Jie Zhou, Sravan Mamidi, Susan Kayser, Jacob Peugh
