| 20100127632 | METHOD, APPARATUS AND COMPUTER-READABLE MEDIA FOR CONTROLLING LIGHTING DEVICES - The present invention is directed to method, system and computer-readable media for controlling lighting devices. In some embodiments, a method for controlling pulse width modulated lighting devices within a lighting apparatus comprising a plurality of sets of lighting devices is disclosed. The method includes setting a counter for a first set of the plurality of sets of lighting devices using a master counter and an activation duration for one or more other sets of the plurality of sets of lighting devices. The method further includes determining an activation time period within a duty cycle for the first set of lighting devices using the counter for the first set of lighting devices and an activation duration for the first set of lighting devices. In some embodiments of the present invention, the lighting devices are light emitting diodes grouped into sets (or banks) and controlled to limit the magnitude and/or quantity of instantaneous current fluctuations in a power supply within the lighting apparatus. | 05-27-2010 |
| 20110279040 | METHODS AND APPARATUS FOR CHANGING A DC SUPPLY VOLTAGE APPLIED TO A LIGHTING CIRCUIT - Methods and apparatus for changing a DC supply voltage applied to a lighting circuit are disclosed. In specific cases, a constant voltage power supply is used to power an LED lighting circuit in which there are uncertainties within the forward voltages of the LEDs, which in turn creates uncertainty with respect to the current level flowing through the LEDs. To manage these uncertainties, the current flowing through the LEDs is measured and an indication of the current level is communicated to a person who can manually adjust the DC voltage supply applied to the LED lighting apparatus by the constant voltage power supply. Alternatively, an automatic adjustment of the DC voltage supply applied to the LED lighting apparatus by the constant voltage power supply can be performed based upon the measured current level. | 11-17-2011 |
| 20110279048 | CIRCUITS FOR SENSING CURRENT LEVELS WITHIN LIGHTING APPARATUS - Circuits for sensing current levels within an apparatus are disclosed. In specific cases, a constant voltage power supply is used to power an LED lighting apparatus in which there are uncertainties within the forward voltages of the LEDs, which in turn creates uncertainty with respect to the current level flowing through the LEDs. To manage these uncertainties, the current flowing through the LEDs is measured by determining a voltage level across a known resistor and calculating the current level. To prevent the known resistor from causing a significant reduction in the efficiency of the overall light engine, the circuit includes one or more transistors in parallel with the known resistor to reduce the effective resistance in the LED circuit during times that the current is not being sensed. | 11-17-2011 |

| 20100010987 | Searching system having a server which automatically generates search data sets forshared searching - A system has a primary server storing search data sets (“staks”) and a linked social network server. Interaction with the server is via a client and a Web site. There is a software agent code executing on the client. The software agent component provides full integration with underlying search engines so that users can continue to search in the normal way, using their favourite search engines, while benefiting from management of search staks, automatic stak selection, and result promotion. The system allows users to manage their staks and providing a range of social networking style services to help users make contact with other like-minded searchers. In addition, it allows users to search for relevant staks. The software agent component provides browser-based access to allow users to manage and share their searchers direct from their browser, as well as providing the benefits of search promotions as they search normally. The Web site provides a wide range of additional features to users and allows them to monitor their own activity and stak activities in more detail, and includes a wide range of social networking style features based around the sharing of search information. The engine provides back-end functionality needed to drive a search service including: the management, storage and indexing of stak information; the generation of search promotions; user management; stak search and recommendations. | 01-14-2010 |

| 20080299844 | AMPHIBIOUS VEHICLE TRANSMISSION - An amphibious vehicle has retractable road wheels to allow planing over water. Power to the road wheels is disconnected automatically as the wheels are retracted. This may be achieved through a cable attached to a suspension rocker arm to disconnect a dog clutch attached to the input shaft of a differential as the wheels are retracted; and vice versa. The system may be fitted to a steered axle or to any suitable retractable suspension system. | 12-04-2008 |
| 20120108118 | AMPHIBIOUS VEHICLE - A sit-astride amphibious vehicle configuration which supports a high performance envelope both on land as well as in water. The vehicle has a planing hull and four retractable wheels. Handlebars provide for directional control in both modes of operation. Each road wheel is retractable by pivoting through at least 45° so as to maximize ground clearance when in the land mode of operation and to minimize drag at substantial lean angles when in the marine mode of operation. While a jet drive may remain directly connected to the engine at all times, the driven wheels are only connected during land mode via a speed-change transmission. The entire power train is supported by a frame that is separable from the hull which in turn has a detachable top deck portion, whereby such configuration simplifies the construction, repair and servicing of the vehicle. | 05-03-2012 |
