Abstract: A controller for controlling a power converter includes a signal generator and a driver. The power converter receives an input voltage and provides an output voltage to power a load. The signal generator receives a sense signal indicating a current flowing through the power converter, receives a detection signal indicating whether the power converter operates in a predetermined state, and generates a square wave signal according to the sense signal and the detection signal. The square wave signal has a first voltage level proportional to a peak level of the current when the power converter operates in the predetermined state; otherwise, the square wave signal has a second voltage level. The driver generates a driving signal based on the square wave signal to control a current flowing through the load.

Abstract: Embodiments of the invention provided a driving circuit for powering a light-emitting diode (LED) light source. The driving circuit includes a rectifier, a s filter capacitor, and a control circuit. The rectifier converts an AC voltage from an AC power source to a rectified AC voltage. The filter capacitor coupled to the rectifier filters the rectified AC voltage to provide a DC voltage. The control circuit controls power supplied to the LED light source. The control circuit enables a discharging current periodically to discharge the filter capacitor if a switch coupled between an AC power source and a rectifier is turned off and disables the discharging current if the control circuit determines that the switch is turned on.

A controller coupled to the first inductor can control a switch coupled to the first inductor, thereby controlling a current flowing through the first inductor. A current sensor coupled to the first inductor can provide a first signal indicative of the current flowing through the first inductor, regardless of whether the switch is on or off. The switch is controlled according to the first signal. A second inductor magnetically coupled to the first inductor is also electrically coupled to the first inductor via a common node between the switch and the first inductor for providing a reference ground for the controller.

Abstract: A re-keyable cylinder lock includes a plug inserted into a lock housing and having a plurality of radial holes connected to a key hole. The lock housing has a first engaging element provided in an inner surface thereof. A limit unit has a second engaging element and is inserted into one of the radial holes located at a predetermined depth of the key hole. The first engaging element engages the second engaging element to limit the plug from rotating when a replacement key which is inserted into the key hole for re-keying does not reach a predetermined depth of the key hole. Incomplete re-keying can therefore be prevented.

Abstract: A door lock assembly includes a transverse retaining plate disposed inside a spindle tube and having a stabilizing part and a retaining tongue projecting into a retention slot in a handle. A support structure is disposed within the handle oppositely of the retention slot and has a support part extending radially into the spindle tube. When the door lock assembly is in a locking state and when the retaining tongue in the retention slot is pressed externally, one of two diametrically opposite edges of a tailpiece of a key plug abuts against the support part, and the other one of the edges abuts against the stabilizing part of the retaining plate to restrict the retaining tongue from moving away from the retention slot, thereby preventing undesirable removal of the handle from the door lock assembly.

Abstract: A circuit includes a transformer and a controller. The transformer includes a primary winding and a secondary winding, and operates in multiple switching cycles. A switching cycle includes a charging period and a discharging period. During the charging period, the transformer is powered by the input voltage and a current flowing through the primary winding increases. During the discharging period the transformer discharges to power the load and a current flowing through the secondary winding decreases. The controller includes a pin that receives a first feedback signal indicating the input voltage during the charging period and receives a second feedback signal indicating an electrical condition of the secondary winding during the discharging period. The controller generates a first control signal and a second control signal to regulate the input voltage and an output current flowing through the load, respectively.

Abstract: In a handle-returning device of a cylinder lock assembly, a support base has an inner annular flange and an axial spring-retaining lug. A rotation driver has an inner tubular wall extending into the inner annular flange of the support base, and a spring driving element. A torsion spring is disposed around the inner annular flange and between the support base and the rotation driver, and has a spring leg abutting the spring-retaining lug and the spring driving element. A rotary plate abuts the support base opposite to the rotation driver, and has an engaging part engaging a tongue projecting from the rotation driver. A reinforced structure is thus provided to oppose high torsional stresses produced upon rotation of a lever handle.
