| 20110221352 | METHOD FOR CONTROLLING AN ELECTRICAL LOAD - A method for controlling an electrical load of at least two single loads includes activating and deactivating the single loads in switching cycles of predefined duration sequentially following one another. In one switching cycle, the single loads are activated and deactivated alternately with respect to one another. | 09-15-2011 |
| 20100237787 | PROCESS AND CIRCUITRY FOR CONTROLLING A LOAD - A current source and an associated method for supplying current to a load such as an arrangement of LEDs. The intensity of the supplied current varies as a function of the temperature of the load. The intensity of the current is temperature-dependent and limited to a predefined maximum. The temperature dependence is achieved by the component parts that are used without the help of special temperature sensors. The current source is supplied with a reference voltage derived from an integrated circuit. The reference voltage is tapped from a port of the IC and therefore it is switchable. The reference voltage is used to produce a control current, which is fed through a driver stage to produce the current of the current source. Elements in the current source limit the current's intensity and change it as a function of temperature. | 09-23-2010 |
| 20100017661 | METHOD FOR DETECTING A FAULT ON A DATA LINE - Multiple embodiments relate to a method for detecting a fault on a data line in a bus system in a two-line data network having at least two control units. A data signal is emitted by a transmitter-receiver unit on the two data lines as a differential voltage signal that includes a defined quiescent current. The data lines are mutually connected through a resistance bridge for detecting the middle voltage. The middle voltage is detected directly by a microcontroller after a low-pass filter or as a digital value after an analog-to-digital conversion. The result is displayed and/or stored. A circuit arrangement for implementing the method is also provided. | 01-21-2010 |
| 20090244824 | MODULAR KEYFOB WITH PIVOTING ARMATURES - In at least one embodiment, a keyfob assembly comprising a housing and a battery chamber is provided. The housing includes a plurality of electrical components positioned therein for transmitting radio frequency (RF) signals to a vehicle. The battery chamber is positioned within the housing and includes at least one removable battery operably coupled to the electrical components for powering the electrical components. The battery chamber is capable of being slideably removed from the housing to facilitate battery exchange. | 10-01-2009 |
| 20090168274 | METHOD AND SYSTEM OF PROVIDING OVERLOAD AND SHORT-CIRCUIT PROTECTION FOR SWITCHED MODE POWER SUPPLY - A method of providing overload and short-circuit protection for a Switched Mode Power Supply (SMPS). The method may rely upon sensing a temperature change rate for a component of the SMPS and implementing a protection scheme when the temperature change rate exceeds a desired temperature change rate. The implementation scheme may include permanently or temporarily shutting-off the component. | 07-02-2009 |
| 20090086983 | METHOD AND SYSTEM FOR TRANSMITTING AUDIO SIGNALS - A system and method of transmitting audio signals. Frequency modulated carrier signals that each have an audio signal are mixed. The mixed signal is converted into a low voltage signal into which a feed voltage is coupled. The coupled signal is transmitted through a single line of a transmission cable to an audio signal infrared transmitter unit. | 04-02-2009 |
