A lifting device including a first platform, a second platform, a gas spring and a locking device is provided. The first platform includes a base and a first column connected to each other. The second platform includes a working table and a second column connected to each other. The second column and the first column are movably connected. The second column has a plurality of engaging holes. The gas spring includes a first end and a second end opposite to each other. The first end connected to the first column, and the second end connected to the second column. The locking device partially disposed at the first column, and a portion of the locking device being adapted to penetrate the engaging holes to fix a relative position between the second column and the first column.

A removable display hoist includes a first clamp configured to be removably coupled to a first portion of a telescoping support member, a second clamp configured to be removably coupled to a second portion of the telescoping support member, and an actuator assembly coupled between the first clamp and the second clamp, where the actuator assembly is configured to extend and retract the removable display hoist.

An electrically adjustable piece of furniture comprises a first and at least one second actuator for adjusting a component of the piece of furniture and a controller for controlling the first and at least one second actuator. The actuators each have a first element and a second element which are displaceable relative to each other, and a sensor attached to the first element and adapted to measure a distance between the first and second elements. The distance measurement is based on a time-of-flight measurement of a wave. The controller is arranged to determine an absolute position of each actuator from the respectively measured distance.

Systems and methods are disclosed for moving a tabletop of a workstation based on biometric input associated with a user, the method being performed by a controller that is configured to send control signals to actuators to move the tabletop. One method includes: accessing a user profile associated with a user device; determining parameters for moving the tabletop, based on the user profile, for eliciting desired biometric inputs from the workstation user at one or more times during the movement of the tabletop; and repeating one or more iterations of: moving the tabletop based on the parameters, by sending control signals to the actuators of the tabletop; receiving, into a data storage device, actual biometric inputs from the workstation user; comparing the received actual biometric inputs with the desired biometric inputs; and if the parameters do not elicit the desired biometric inputs, adjusting the parameters.

A table carried at the distal end of a table leg that is configured for anchoring entirely on a toilet. The table leg is anchored at its proximal end to an upside-down J-bracket configured to couple with the rim of a toilet bowl. A J-bracket typically includes a clamping mechanism to horizontally squeeze the rim. Table elevation above floor level may be adjusted by way of a telescopic table leg, and/or a coupling mechanism between the proximal table leg end and the J-bracket. Horizontal orientation of the table top surface may be maintained by an anti-twist mechanism and an anti-roll mechanism.

A device for table elevation includes: two decorative covers; two guiding bases connected by a connecting rod and each having four fixed sides; plural guide bearings provided in pairs, each pair arranged opposite, and at an angle with respect to, each other; two guide posts having plural guided sides corresponding in number and position to the fixed sides, the guided sides being in contact with the guide bearings so that the guide posts can slide with respect to the guiding bases respectively, the guide bearings abutting against the guided sides in the aforesaid pairs; two driving units each including an elevating rod; and a tabletop with a guide post fixing base fixed at the top ends of the guide posts and of the elevating rods so as to move vertically with the elevating rods and the guide posts while the decorative covers and the guide posts stay vertical and stable.

The present disclosure relates to an operating table, the operating table comprising a table top, a table top support and a column with a column head, wherein the sealing device is bellows assembled below the column head, or an adhesive in a hole and/or window on the holder of the cable, or a sealing gasket between the receiver and the column head, or a shield sealingly attached to the column head below the gear. The present disclosure further relates to control equipment, a lifting device, an intelligent charger, a column guide system for an operating table, as well as an operating table including the same.

A display hoist includes a first clamp configured to be coupled to a first portion of a telescoping support member, a second clamp configured to be coupled to a second portion of the telescoping support member, and an actuator assembly extending between the first clamp and the second clamp. The actuator assembly includes an actuator motor, a piston including a first end and a second end, the first end of the piston mechanically coupled to the first clamp, the second end of the piston operably coupled to the actuator motor, and a housing disposed over at least a portion of the piston and enclosing the actuator motor, the housing including a top end and a bottom end, the housing mechanically coupled at the top end to the second clamp.

A height adjustable desk includes a worksurface, a first leg and a second leg connected to the worksurface. The first leg is provided with a first motor to drive a first lifting apparatus for telescoping the first leg, while the second leg is provided with a second motor to drive a second lifting apparatus for telescoping the second leg. Each of the first motor and the second motor is provided with a magnetic device and two sensors. The magnetic device has several N-pole sections and S-pole sections, and the sensor detect a change of a magnetic field when the motor is turning. A control unit receives the signals of the sensor, and changes a speed of at least one of the motors until the signals are synchronous again when the control unit found that the signals are not synchronous.
