Publication number: 20210251834Abstract: A method of rotating a subject includes arranging a lifting aid underneath the subject such that a midline of the subject is off center from a centerline of the lifting aid in a direction opposite of the rotation direction. The lifting aid includes a first loop extending in the rotation direction and a second loop extending in the opposite direction. The method further includes connecting the loops to a sling bar coupled to an overhead lift and directing the overhead lift to raise, where the subject rotates towards the direction of rotation due to the off center location of the subject. The method further includes repositioning the subject when the subject has rotated to a lateral recumbent position and directing the overhead lift to lower, thereby causing the subject to continue rotating.Type: ApplicationFiled: February 1, 2021Publication date: August 19, 2021Applicant: LIKO RESEARCH & DEVELOPMENT ABInventors: Neal Wiggermann, Michael Buccieri, Alejandro Noe Conejo Castaño, Morgan Dreyer, Jie Zhou, Lori Ann Zapfe

Publication number: 20210236363Abstract: An overhead lift system may include a motor and a lift strap connected to the motor. The motor raises and lowers the lift strap. A hand controller may be communicatively connected to the motor. The hand controller includes a force sensor associated with the body of the hand controller such that force applied to the body is detected with the force sensor. An orientation sensor may also be arranged within the body and determines an orientation of the hand controller. A control unit may be communicatively connected with the motor, the force sensor, and the orientation sensor. The control unit detects a force applied to the hand controller with the force sensor, determines a direction of motion of the hand controller with the orientation sensor, and provides a signal to the motor to raise or lower the lift strap based on the force and orientation of the hand controller.Type: ApplicationFiled: January 28, 2021Publication date: August 5, 2021Applicant: Liko Research & Development ABInventors: Jesse Newman, Christopher Yeckel, Joseph Tari, Sravan Mamidi, Jackie Berkebile, Jessica Cushman

Patent number: 11007101Abstract: A motive system for a patient lifting assembly, a patient lifting assembly and a method of operating a patient lifting assembly. The motive system includes an electric motor, numerous sensors and an adaptive control unit cooperative with one another so that a memory and processor that are part of the control unit that can respectively store and execute a computer readable and executable instruction set. By comparing collected data from the sensors during operation of the motor to corresponding reference values associated with one or more motor operational parameters—such as accumulated motor wear over time or differences in operating temperature of the motor—the system can selectively adjust the maximum amount of current available for use by the motor. In this way, changes in motor efficiencies that arise with these parametric changes can be taken into consideration when determining an upper limit on how much electrical current may be delivered to the motor for a given load.Type: GrantFiled: April 25, 2018Date of Patent: May 18, 2021Assignee: LIKO RESEARCH & DEVELOPMENT ABInventors: Joakim Eriksson, Mattias Andersson, Erik Gustafsson
