20080297960 | INTEGRATED CIRCUIT AND ELECTROSTATIC DISCHARGE PROTECTION CIRCUIT - An integrated circuit and a protection circuit capable of protecting electrostatic discharge (ESD) damage. The integrated circuit comprises a first pad, a ground pad, a second pad, a device circuitry, a discharging unit, and a discharging controller. The discharging unit comprises first and second transistors in series. The discharging controller comprises an ESD connection unit, and a voltage clamping unit. The ESD connection unit, coupled to the first pad and the discharging unit, receives an ESD pulse to establish a first control voltage to turn on the first transistor in the ESD event. The voltage clamping unit, coupled to the ESD connection unit and the first, second and ground pads, clamps the ESD pulse to establish a second control voltage to turn on the second transistor in the ESD event, and receives an operation voltage at the first pad to turn off the second transistor in normal operation. | 12-04-2008 |

20150209204 | INTELLIGENT WALKER - An intelligent walker includes a holder, a support frame, a sensing grip, a driving device, and a control device. The support frame is configured for supporting the holder. The bottom side of the support frame is disposed with a plurality of wheels. The driving device is configured for driving the wheels so as to move the intelligent walker. The sensing grip is disposed behind the holder and has a pressure-sensing element. The pressure-sensing element is configured for sensing the magnitude of a force of a user's hands and a position of the user's hands on the sensing grip and for generating a sensing signal. The control device is connected to the pressure-sensing element and the driving device, and configured for receiving the sensing signal and generating a control signal. The driving device receives the control signal and correspondingly changes the movement speed and direction of the intelligent walker. | 07-30-2015 |
