| 20120086475 | ELECTRONIC LOAD OF SEMICONDUCTOR ELEMENT - An electronic load for a semiconductor element is provided. The electronic load includes at least two slope generating circuits, each of which generates a current according to a current for the electronic load corresponding to an output voltage of a power supply. Each slope generating circuit comprises at least a first slope generating circuit that simulates a first slope when the output voltage of the power supply is between 0V to a rated voltage, and a second slope generating circuit that simulates a second slope when the output voltage of the power supply is higher than the conducting state voltage of the semiconductor element by subtracting the forward bias voltage from the output voltage of the power supply. | 04-12-2012 |
| 20120078385 | SMART ELECTRONIC CONNECTING DEVICE - A smart electronic connecting device applicable to control the electronic connection between an external power supply and an external electronic connector includes an input unit connected to the external power supply, a processing module, a mode generation unit, an output unit and a relay unit connected between the input unit and the output unit. The processing module has a timing generation unit generating a timing signal, a control unit generating a control signal, and a memory unit. The mode generation unit generates multiple mode selecting signals to the control unit. The output unit is to connected to the external electronic connector. The relay unit is turned on/off selectively according to the control signal of the control unit to conduct the input unit and the output unit, wherein the memory unit records the turn-on connection status of the relay unit within the predetermined period to recur the turn-on connection status. | 03-29-2012 |
| 20110302433 | CONTROL CIRCUIT OF POWER-SAVING SOCKET - A control circuit is provided for a power-saving socket and includes a central processing unit, a relay, a sensor unit, a time counting unit, a standby current setting unit, and a current monitoring unit. The central processing unit, upon receiving a human approaching signal from the sensor unit, issues a control signal to the relay to switch a contact of the relay to a closed condition, whereby an electrical appliance plugged to the socket is allowed to operate. When the electrical appliance plugged to the socket stays in a standby mode, the central processing unit receives a current value from the current monitoring unit, which is equal to or smaller than an appliance standby current level, and the time counting unit starts time counting for a specific period of time. Once the detected current value from the current monitoring unit maintains equal to or smaller than the appliance standby current level within the whole specific period of time, the central processing issues a control signal to the relay to switch the contact of the relay to an open condition, whereby power supplied to the electrical appliance plugged to the socket is completely cut off and the electrical appliance consumes no standby power. In this way, power saving can be achieved. | 12-08-2011 |
| 20110270458 | ELECTRICAL SOCKET APPARATUS WITH OVER-CURRENT PROTECTION - An electrical socket apparatus with over-current protection is disclosed, including at least two sockets, at least one breaker switch, a current detection unit and a microprocessor. The sockets are coupled in parallel to a power system. The breaker switch is installed in the path of one of the sockets coupled to the power system for breaking or connecting the path of the sockets to the power system. The current detection unit detects the current flowing into the sockets and outputs a set of current values. The microprocessor is coupled to the current detection unit for receiving the set of current values, determining whether a total current flowing into the sockets exceeds a current threshold value and breaking the breaker switch according to a predetermined breaking data when total current flowing into the sockets exceeds the current threshold value. | 11-03-2011 |
