Apparatus, methods, and computer-readable medium are disclosed for controlling positioning of a desk. An exemplary apparatus includes a tabletop, expandable legs, motors, position sensors, a processor, and a memory configured to store instructions. The motors alter a length of one of the expandable legs. The position sensors identify current position of each of the plurality of expandable legs. The instructions cause the processor to receive a sensor signal, a communication signal, or a command signal, receive the identified current position of one or more of the expandable legs, determine a projected length value for the one or more expandable legs responsive to the received sensor signal, the communication signal, or the command signal, and command one or more of the plurality of motors based on the projected length value for the one or more expandable legs and the identified current position of the one or more expandable legs.

A system for managing the elevation of a workstation, the system comprising a frame, a worktop having an upper worksurface, at least a first powered vertical-displacement drive mechanism connected between the frame and the worktop and arranged to selectively vertically displace the worktop with respect to the frame, a presence sensor and a processor linked to the drive mechanism and the sensor, the processor using information from the presence sensor to track user presence at the workstation and, upon detecting that the workstation is unoccupied, automatically controlling the drive mechanism to move the worktop from a current height to a scheduled height.

In one aspect, a device includes at least one processor and storage accessible to the at least one processor. The storage includes instructions executable by the at least one processor to identify a context associated with a user and to alter a height of an electronic desk based on the context.

A collision prevention control system based on an electric lifting table and a collision prevention method thereof are provided. The collision prevention control system includes a lifting table, an electronic lifting table control box disposed on the lifting table, and a single-chip microcomputer disposed in the electric lifting table control box. The electric lifting table control box is internally provided with an acceleration and gyroscope chip, the acceleration and gyroscope chip performing synchronous motion with the lifting table, the acceleration and gyroscope chip being in information interaction with the single-chip microcomputer, and motion control on the lifting table being performed through the single-chip microcomputer. The collision prevention control system has the advantageous effects as follows: has higher sensitivity and more reliable operation, and senses a slight angular change or an acceleration change when the lifting table encounters resistance.

A workstation including a height-adjustable work surface is described. The workstation includes a frame, and the work surface is configured to translate relative to the frame to vary a height of the work surface. A lift assembly configured to assist translation of the work surface relative to the frame. The lift assembly includes a moveable component and translation of the moveable component results in a translation of the work surface relative to the frame. A translation sensor is coupled to one of the frame or the movable component, and it is configured to measure translation of the moveable component relative to the frame. A control circuit is in communication with the translation sensor to determine an amount of translation of the work surface relative to the frame.

The present invention provides methods and a workstation that includes a work table, wherein the work table includes: a first work surface and a second work surface, wherein the second work surface is configured to have vertical movement such that the second work surface can be selectively placed in a first plurality of vertical positions relative to the first work surface, and a first motor operatively coupled to the second work surface and configured to power the vertical movement of the second work surface; and a plurality of legs coupled to the work table, wherein the plurality of legs is configured to support the work table above a ground surface, and wherein the plurality of legs includes a lift mechanism configured to raise and lower the plurality of legs such that the work table can be selectively placed in a plurality of height configurations relative to the ground surface.

This invention provides a multifunctional lifting table, and the multifunctional lifting table includes a tabletop, an outer frame, an inner frame, and a lifting mechanism. The tabletop includes a tabletop main body and a solar panel, and the solar panel is embedded into the tabletop main body. The solar panel has at least one output interface, and the output interface is located at one side of the tabletop main body. The inner frame supports the tabletop, the outer frame has a containing space therein, and the inner frame is embedded into the containing space of the outer frame. The lifting mechanism is connected with the inner frame and the outer frame, and the lifting mechanism drives the inner frame to rise from the outer frame or to lower the inner frame and allow the inner frame to be hidden inside the outer frame.

The invention provides a lifting desk control method including a motor drive unit, a current detection unit and an arithmetic unit. The control method comprises the steps of: detecting current a at the current time t1 and current b at time t2; calculating the current change rate L=(ba)/(t2t1); and comparing L with a set value, judging that an obstacle is encountered if the set value is exceeded, and issuing a stopping or retreating instruction to a motor by the motor drive unit. The scheme employed by the invention is to calculate the change rate of current, so judgment is made with higher accuracy and whether an obstacle is encountered is judged with high sensitivity.
