    Abstract: A cylinder lock has a cylindrical plug which is formed with a longitudinally extending keyway and which has a plurality of pin tumblers extending into the keyway. Each of the pin tumblers has a cylindrical outer part and a concentric inner part telescopically slidable within the outer part. A key is inserted into the keyway and has a tumbler activating side which is formed with a longitudinally extending groove, a groove base having projections and/or recesses formed therein and a pair of upwardly extending key blades joined by the groove base. The inner part of each of the pin tumblers has a distal end which extends into the groove and which engages a corresponding one of the projections and/or recesses. The key blades are formed with matching key bit grooves which engage the outer parts of the pin tumblers. Each of the key bit grooves has a groove bottom which is disposed above the groove base, thereby permitting a relatively large difference between the lengths of the inner and outer parts of the pin tumblers so as to increase correspondingly the number of possible lock combinations and the difficulty in picking the cylinder lock.

    Abstract: A driving circuit for controlling power of a light-emitting diode (LED) light source includes a transformer, a switch controller, and a dimming controller. The transformer has a primary winding that receives input power from an AC/DC converter and a secondary winding that provides output power to the LED light source. The switch controller coupled between an optical coupler and the primary winding receives a feedback signal indicative of a target level of a current flowing through the LED light source from the optical coupler, and controls input power to the primary winding according to the feedback signal. The dimming controller coupled to the secondary winding receives a switch monitoring signal indicative of an operation of a power switch coupled between an AC power source and the AC/DC converter, and regulates the output power by adjusting the feedback signal according to the switch monitoring signal.

    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: A driving circuit includes a first inductor coupled in series with a light source for providing power to the light source. 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. The reference ground is different from the ground of the driving circuit.

    Abstract: A dimming controller for controlling power of a light source has a monitoring terminal, a dimming terminal, and a control terminal. The monitoring terminal is operable for receiving a current monitoring signal indicating a current flowing through the light source. The dimming terminal is operable for receiving a ramp signal. The voltage of the ramp signal increases if a power switch coupled between a power source and the light source is turned on. The control terminal is operable for providing a control signal to control a control switch coupled in series with the light source based on the current monitoring signal and the ramp signal. An average current of the light source increases as the ramp signal increases until the average current reaches a predetermined level.

    Abstract: A re-keyable cylinder lock has a control member to permit or restrict transverse movement of a re-keying unit. The control member is movable axially between first and second positions and transversely to a third position from the second position. In the third position, the re-keying unit moves transversely and disengages from first tumbler pieces. A limit member is provided to prevent the control member from moving axially when no right key is inserted into a plug. A security arm is connected to the control member and is breakable so that destructive forces cannot reach the control member.
