Abstract: A desk having a bottom plate, a face plate movably coupled to the bottom plate by one or more support members, a motor configured to selectively move the face plate upward and downward with respect to the bottom plate, and a control mechanism. The control mechanism can have a first sensor device coupled to an upper surface of the bottom plate, the first sensor device having one or more first optical sensors, and a second sensor device aligned parallel to the first sensor device and coupled to a lower surface of the face plate, the second sensor device having one or more second optical sensors in communication with the one or more first optical sensors. The control mechanism can be configured to stop the motor from moving the face plate in response to an object between the first sensor device and the second sensor device.

Abstract: An electrically-lifted computer desk and office desk thereof, wherein the computer desk comprises a bottom plate, a driving mechanism, an intermediate support member, a first side-support member, a second side-support member and a face plate, wherein the driving mechanism is fixedly disposed on the bottom plate; the face plate is fixedly disposed on the first side-support member and the second side-support member; and the driving mechanism drives the face plate to rise or fold via the intermediate support member, the first side-support member and the second side-support member.
