Abstract

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.

First claim

The claimed invention is:

1 . A workstation including a height-adjustable work surface, the workstation comprising:
a frame; a lift assembly operable to assist translation of the height-adjustable work surface relative to the frame to vary a height of the height-adjustable work surface; a sensor configured to generate a first signal indicative of translation of the height-adjustable work surface relative to the frame based on movement of a movable member of the workstation; a processor in communication with processing circuitry; and a memory coupled to the processor, the memory including instructions that, when executed by the processor cause the processing circuitry to:
receive the first signal;
determine, using the first signal, a work surface value associated with movement of the movable member;
determine, using the first signal, a work surface travel time; and
generate, using the work surface value and the work surface travel time, a translation representation indicative of the translation of the height-adjustable work surface relative to the frame.

2 . The workstation of claim 1 , wherein, to determine the work surface travel time, the instructions cause the processing circuitry to compare a first inflection point of the first signal to a second inflection point of the first signal.

3 . The workstation of claim 1 , wherein the first signal is indicative of movement of a movable component of the workstation, and wherein, to determine the work surface value, the instructions cause the processing circuitry to compare the first signal to a reference point.

4 . The workstation of claim 1 , wherein the sensor is an accelerometer, and wherein, to generate the translation representation, the instructions cause the processing circuitry to integrate the first signal over the work surface travel time.

5 . The workstation of claim 1 , wherein the sensor is an accelerometer, and wherein, to generate the translation representation, the instructions cause the processing circuitry to:
determine, by multiplying a representative value of the first signal by the work surface travel time, an average velocity; and determine, by multiplying the average velocity by the work surface travel time, the translation representation.

6 . The workstation of claim 1 , wherein the instructions cause the processing circuitry to:
generate a control signal by comparing the translation representation to one or more pre-determined thresholds; and transmit the control signal to operate the lift assembly.

7 . The workstation of claim 6 , wherein the instructions cause the processing circuitry to:
store a cycle count that corresponds to a number of instances of the processor generating the control signal; and increment the cycle count based on the generated control signal.

8 . The workstation of claim 6 , wherein the control signal causes a display to present one or more operating instructions to a user of the workstation.

9 . The workstation of claim 8 , wherein the one or more operating instructions includes a safety warning.

10 . The workstation of claim 8 , wherein the one or more operating instructions includes a maintenance notification.

11 . The workstation of claim 1 , comprising:
a cloud server, wherein the processor is in communication with the cloud server such that the processor transmits the first signal to the cloud server and the cloud server communicates with the processor to generate one or more control signals based on the first signal.
