20120200229 | MUTLI-STRING LED CURRENT CONTROL SYSTEM AND METHOD - Embodiments described herein provide a LED lighting system and method. A transformer has a primary winding and a secondary winding. A plurality of LED strings are coupled to the secondary winding of the transformer. At least one switch is coupled to at least one of the plurality of LED strings. A controller is coupled to the at least one switch and configured to control the operation of the at least one switch such that current flows through the plurality of LED strings in an alternating manner. | 08-09-2012 |

20130249422 | VARIABLE MASTER CURRENT MIRROR - A variable master current minor circuit may be used to balance the currents through a parallel Light Emitting Diode (LED) strings in an illumination module when the LED string with the largest forward voltage changes due to events, such as a short failure of an LED. The variable master current mirror circuit includes a switching circuit that is coupled to the parallel LED strings and a current minor circuit that is coupled to the parallel LED strings and the switching circuit. The switching circuit switchably connects the LED string with the largest forward voltage to the current minor circuit as a master LED string. The current mirror circuit maintains equal currents through the LED strings with reference to the current through the master LED string. | 09-26-2013 |

20140014676 | CREDIT CARD DISPENSER - A card dispenser can include a planar sleeve, an actuator, and a lifter assembly. More specifically, the planar sleeve can be shaped to receive a plurality of cards within a card chamber. A dispense opening within the planar sleeve can be shaped to pass the plurality of cards edgewise. The actuator can extend along an edge of the planar sleeve. The actuator can be pivotable about an actuator pivot located between a retaining end and an actuation end of the actuator. The actuator pivots from a retaining position to a dispense position. The retaining position orients a card contact surface of the retaining end against the plurality of cards to prevent removal of the plurality of cards. The lifter assembly can be associated with the actuation end and can be oriented adjacent a bottom edge of the card chamber. The lifter assembly can be adapted to apply force to at least one of the plurality of cards, upon movement of the actuator to the dispense position, sufficient to dispense at least one of the plurality of cards from the dispense opening. | 01-16-2014 |
