Patent number: 11938069Abstract: A backrest pivoting system can have a backrest and an actuator for pivoting the backrest. The actuator is pivotably connected to the backrest by a pivot defining a first pivot axis. The backrest can pivot about a guide member which defines a second pivot axis coaxial with the first pivot axis. A backrest pivoting system can include an actuator and a resilient member mounted in series with the actuator. There is also provided an extendable user support assembly comprising a lower body support panel and a core support panel supported by a frame, the lower body support panel being translatable relative to the frame such that an opening is created between the lower body support panel and the core support panel when the lower body support panel is translated away from the core support panel. There is also provided a method for placing a bed in a vascular position.Type: GrantFiled: January 24, 2022Date of Patent: March 26, 2024Assignee: UMANO MEDICAL INC.Inventors: Sylvain Lacasse, Steve Bolduc, Jimmy Laflamme, Guy Lemire, Jean-Philippe Beaudet, Gabriel Mercier, Esther Berthelot

Patent number: 9085243Abstract: An equalization system for batteries has two series-connected accumulator stages connected, each including an accumulator, a voltage generator including positive and negative poles, for each stage, an associated charging device supplied by the voltage generator. The charging device includes an inductor having a first and second ends, and a capacitor having first and second ends. The capacitor's first end connects to the generator's positive pole. It also has a diode whose anode connects to a negative pole of the accumulator stage and whose cathode connects to the inductor's first end. It also has a switch whose first end connects to the inductor. And it also has a control device that controls the generator and closes a switch of a charging device associated with an accumulator stage to be charged so that the inductor stores energy, and causes its transfer to that accumulator stage.Type: GrantFiled: February 4, 2011Date of Patent: July 21, 2015Assignee: Commissariat a l'energie atomique et aux energies alternativesInventors: Daniel Chatroux, Julien Dauchy, Eric Fernandez, Sylvain Mercier
