  • Patent number: 10133261
    Abstract: A sit-stand desk includes a frame located on a floor surface; a panel having an upper work surface and being selectively vertically displaceable in respect to the frame; and a vertical-displacement drive mechanism mechanically connected between the frame and the panel. Activation of the drive mechanism vertically displaces the panel with respect to the frame. The sit-stand desk also includes a control circuit selectively activating the drive mechanism to vertically displace the panel according to prescribed displacement instructions in response to receipt of a trigger signal and a pressure mat located on the floor surface adjacent to the frame on which a user stands. The pressure mat includes a pressure sensor in communication with the control circuit and configured to measure a presence of the user adjacent to the desk.

  • Patent number: 9486070
    Abstract: A sit/stand workstation includes a worktop that includes a powered drive and is moveable between a sitting height and a standing height. During use, a controller moves the worktop up and down following a user-defined schedule and uses sensors, such as a pressure mat, to detect how well the user follows the schedule and biometric indicators that convey fatigue and user energy level. In response to this monitored user information, the controller changes time, duration, and/or frequency of the schedule to better meet the abilities and fitness of the user and also to help encourage the user to continue regular use of both sitting height and standing height workstation positions. Sounds, voice, lights, colors, and numerical information are used to help encourage the user in use of the sit/stand workstation.

  • Publication number: 20140096706
    Abstract: A sit/stand workstation includes a worktop that includes a powered drive and is moveable between a sitting height and a standing height. An electronic controller offers the user different operating modes, each with varying levels of automation. In one such mode, the user inputs a value that represents a desired percentage of standing time over a given period of time. The controller then uses user-profile information and the inputted value to create an initial custom height-adjustment schedule for the user. During use, the controller moves the worktop up and down following the schedule and uses sensors, such as a pressure mat, to detect how well the user follows the schedule and biometric indicators that convey fatigue and also energy. In response to this monitored user-information, the controller changes time, duration, and/or frequency of the schedule to better meet the abilities and fitness of the user and also to help encourage the user to continue regular use.
