Safe detection of an external load attached to an AC power outlet of a power supply stands out as one advantage of the power supply apparatus and method contemplated herein, although other advantages flow therefrom. Not least among the other advantages are a simplicity of design offering an economical and robust mechanism for detecting external loads. The contemplated mechanism relies on the application of a DC voltage to one electrical phase of the AC power outlet and the coupling of that voltage to the other electrical phase of the AC power outlet through an interconnecting resistor. With both phases respectively coupled to voltage divider circuits nominally matched in value, the divided down voltages measured from the respective phases will differ in dependence on the relative size of the interconnecting resistor and the resistive value of any load attached to the AC power outlet.

The invention improves detection accuracy of interposition at a vehicle window. An interposition detector determines that a window at a passenger's seat has interposition if motor current for opening and closing the window at the passenger's seat does not decrease to be less than a predetermined threshold but increases to be not less than a second threshold, or if the motor current does not decreases to be less than the predetermined threshold but increases at a predetermined or more increase rate. The interposition detector determines that the window at the passenger's seat does not have interposition if the motor current is less than the predetermine threshold. The invention is applicable to an automatic window system and the like.
If closing operation to the passenger's seat sub switch continues for not less than a prescribed time period Tb, a passenger's seat relay contact on a close side is turned ON. If the closing operation to the passenger's seat sub switch thereafter ends before a prescribed time period Tc elapses, the passenger's seat relay contact on the close side is kept ON. If opening operation to the passenger's seat sub switch continues for not less than the prescribed time period Tb, a passenger's seat relay contact on an open side is turned ON. If the opening operation to the passenger's seat sub switch thereafter ends before the prescribed time period Tc elapses, the passenger's seat relay contact on the open side is kept ON.

A portable device has an opening formed in one case of a dual structure, a partitioning member for partitioning the opening, a projection formed on the partitioning member so as to project to a front surface side of the case, and at least two push buttons attached from a back surface side of the case to partitions partitioned by the partitioning member. The push button has a substantially flat plate-shaped push button portion, and a locking portion formed at an outer edge of the push button portion. The locking portion contacts an outer edge of the opening to prevent slip-out of the push button when the push button is attached to the partition from the back surface side of the case.

In a key lock structure of a mechanical key of a portable device in which a mechanical key is storable in a main body, the main body is configured in a two-piece structure including a first case and a second case, the first case includes a first storage section for storing the mechanical key and a second storage section for storing a key lock mechanism of the mechanical key, the lock mechanism locks the mechanical key stored in the first storage section to prevent the mechanical key from coming off and unlocks in response to a predetermined operation to allow the mechanical key to be pulled out.
The invention provides a stop lamp lighting controller able to improve durability of a relay while unnecessary automatic turning on and off are avoided. A stop lamp is lit through a main line at a gentle braking time. At a sudden braking time, the stop lamp is switched on and off by disconnecting and connecting the main line in a predetermined period. At a breakdown time of the main line, the main line is switched to a subline and a lighting function of the stop lamp is secured. The main line is formed when both a first relay and a second relay are in a de-energizing state. The main line is disconnected and connected by periodically opening and closing the first relay. The main line is switched to the subline by energizing the second relay.

A resolver signal processing device includes a control portion, a resolver, and an input/output portion. The control portion includes a memory for storing sine wave data for two cycles, and a DMA controller for transmitting to the resolver the excitation signal including a sine wave. A calculation portion provided in the control portion commands, in initial setting, DMA transfer of the sine wave data for one cycle from a reference phase as the excitation signal, and commands, in detecting the rotational angle, DMA transfer of the sine wave data for one cycle from a modified phase as the excitation signal. The modified phase is determined, in the initial setting, based on the phase difference between the excitation signal and a sine wave output signal or a cosine wave output signal, and the rotational angle of the resolver.

A switching device has a switch, a case within which the switch is accommodated, a cylinder which is provided on an upper surface of the case and open to above and below to communicate with the inside of the case, an operation knob which covers an opening of the cylinder and swings in a front-to-rear direction, and an operation bar which extends from the operation knob through the opening into the case to transmit the motion of the operation knob to the switch. A guide member is disposed between the case upper surface and the end of the operation knob. The guide member is inclined in the left and right directions so as to guide water toward the sides of the case.
A distance measuring device for a vehicle emits electromagnetic waves forward for a scan both in horizontal and vertical directions. It is judged from received light whether or not the distance to a detected object is within a specified preset range. If the distance is found to be within this range and if at least two specified conditions are satisfied, this object is regarded as a vehicle in the subsequent scans and a flag is set to this effect. One of these two conditions requires this object to have been judged as being a front going vehicle continuously over a time longer than a preset minimum time length. The second condition is that the difference between the distance to this object measured by a scan that is the highest or nearly the highest in the vertical direction and the measured distance to a front going vehicle corresponding to the object is within a predetermined range.
