Abstract:
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.

Claim (Index 1):
A height adjustable desk, comprising:\n a worksurface; a first leg and a second leg connected to a bottom of the worksurface; a first motor and a first lifting apparatus provided in the first leg, wherein the first motor drives the first lifting apparatus to telescope the first leg; a second motor and a second lifting apparatus provided in the second leg, wherein the second motor drives the second lifting apparatus to telescope the second leg; a first magnetic device connected to a shaft of the first motor to be turned with the first motor, wherein the first magnetic device has a plurality of N-pole sections and a plurality of S-pole sections alternately arranged in an annular pattern; a first front sensor and a first rear sensor provided in the first leg and adjacent to the first magnetic device to detect a change of a magnetic field when the first magnetic device is turning; a second magnetic device connected to a shaft of the second motor to be turned with the second motor, wherein the second magnetic device has a plurality of N-pole sections and a plurality of S-pole sections alternately arranged in an annular pattern; a second front sensor and a second rear sensor provided in the second leg and adjacent to the second magnetic device to detect a change of a magnetic field when the second magnetic device is turning; and a control unit receiving signals from the first front sensor, the first rear sensor, the second front sensor, and the second rear sensor; whereby when the signals of the first front sensor and the first rear sensor and the signals of the second front sensor and the second rear sensor are not synchronous, the control unit controls at least one of the first motor and the second motor to change a speed thereof until the signals of the first front sensor and the first rear sensor and the signals of the second front sensor and the second rear sensor are synchronous again.
