Abstract: A vehicle includes a first sensor, a second sensor, an engine, a fuel supplying device, and a control device. The control device includes a first sensor detecting unit, a second sensor detecting unit, a vehicle status detecting unit, and a control unit. The control unit is switchable among a regular state, a start-stop enabling state, and an idling-stop state. The control unit switches into the start-stop enabling state from the regular state once the control unit determines that the first sensor and the second sensor are both triggered. The control unit further switches into the idling-stop state and controls the fuel supplying device to stop supplying fuel once the control unit determines that the vehicle status meets an idling-stop condition.

Abstract: A method for estimating operation parameters of a servomotor is described. The method includes the steps of: driving the servomotor to rotate stably at an initial angular velocity; computing d- and q-axis components of an initial voltage when the servomotor rotates at the initial angular velocity; accelerating the servomotor to a predetermined angular velocity according to the initial voltage; and computing at least one operation parameter of the servomotor after the servomotor rotates at the predetermined angular velocity.

Abstract: A lens, which is adapted to control distribution of light emitted by a light source, includes a curved light-projecting surface distal from the light source, and a light-incident surface opposite to the light-projecting surface. The light-incident surface includes a plurality of curved sections facing the light source, and a plurality of connecting sections. Each of the connecting sections interconnects two adjacent ones of the curved sections, and has opposite first and second connection sides that are respectively connected to the two adjacent ones of the curved sections. A distance between the first connection side and the light source is not equal to a distance between the second connection side and the light source.

Abstract: A power supply apparatus includes a switch, a converting module and a control module. When the switch operates in an ON state, an input voltage is outputted through the switch to serve as an output voltage. The converting module selectively converts the input voltage into the output voltage. When the power supply apparatus operates in a mode where the switch operates in an OFF state, where the converting module performs the conversion, and where the output voltage is stabilized at a target voltage value, and when a condition associated with the input voltage is met, the control module causes the output voltage to gradually change toward the input voltage.

Abstract: A power distribution unit is connected to a three-phase electric power source having three phase wires with different phases, and includes a socket and a switch. The socket has a first socket terminal connected to one of the phase wires, and a second socket terminal. The switch includes a first switch terminal connected to another one of the phase wires, a second switch terminal connected to a neutral, and a third switch terminal connected to the second socket terminal. By selectively connecting the third and the first switch terminals, or connecting the third and the second switch terminals, a line-to-neutral voltage or a line-to-line voltage from the three-phase electric power source is outputted by the socket.

Abstract: A quasi-resonant half-bridge converter includes a switch unit including first and second switches that are coupled in series, a capacitor unit coupled to the switch unit in parallel, a rectifier unit, an output capacitor, and a transformer coupled to the aforesaid components. The first and second switches are respectively controlled using first and second control signals that have a constant frequency. Duty cycles of the first and second control signals may be adjusted based upon a DC output voltage across the output capacitor for promoting conversion efficiency of the converter when operating at light load.
