20090014625 | METHOD AND SYSTEM FOR CONTROLLING A LIGHTING SYSTEM - A system is provided for automatically controlling a light level of an interior space. The system may include a light sensor, a transmitter, and a lighting system. The light sensor measures a light level of an interior space and sends the measured light level to the transmitter. The transmitter is in electrical communication with the light sensor. The transmitter is configured to receive the measured light level from the light sensor; to compare the received light level with a light level setting; to determine a value for a lighting indicator based on the comparison; to define a control signal including the determined value; and to send the defined control signal to a first receiver. The lighting system may include a light fixture and a second receiver mounted on the light fixture. The second receiver is configured to receive the control signal, to extract the determined value from the received control signal, and to adjust a light level of the light fixture based on the extracted value. | 01-15-2009 |

20090243559 | UNIVERSAL, FAIL-SAFE, COMMON CONTROL OF MULTIPLE ALTERNATORS ELECTRICALLY CONNECTED IN TANDEM PARALLEL FOR PRODUCING HIGH CURRENT - Two or more alternators—each typically of an economical cost and of any mixture of types and capacities—are turned by a single power source—normally the engine of a large commercial truck or bus burning fuel so as to produce minimum emissions and thus operating at such higher combustion temperature as does raises the ambient temperature of the engine compartment to 125° Celsius. The several alternators are electrically connected in tandem-parallel across a battery/load. A corresponding number of identical electronic voltage regulators, preferably of the type described in U.S. Pat. No. 5,723,972 modified according to the present invention, respectively individually control the alternators. One electronic voltage regulators externally programmed to become a designated “master” produces a “universal” control signal in response to variations in a voltage across the battery/load. This “universal” control signal is used (1) in the “master” electronic voltage regulator itself to provide regulation to an associated alternator, and is wired to all other voltage regulators externally programmed as “followers” to (2) produce in each of these voltage regulators produces a signal for the regulation control of its associated alternator not by reference to the battery/load voltage (as would be normal), but rather by reference to the “universal” control signal. | 10-01-2009 |
20090243560 | Pulse-position-modulated vehicular alternator voltage regulator with dual AC-feedback networks, controlled "OFF" period and low inserted electrical noise - A Frequency-On-Demand type voltage regulator firstly has its power output circuit configured as a resettable monostable multivibrator that provides (1) a stable time-base that serves as an internal “OFF”-period reference; preferably also with (2) short-circuit protection to the output power transistor; and (3) a pulse train with sharply defined “ON” and “OFF” transitions as the result of the interaction between the Output and Input Stages of the Power Output Circuit through a first AC Feedback Network. The “ON” and “OFF” transitions are preferably rounded-off. Secondly, yet another, second, AC feedback network is added between the Output Stage of the Power Output Circuit and the Error-Detector/Voltage Divider Stage of the Frequency-On-Demand type voltage regulator. This second feedback network provides (1) a controlled “OFF”-period synchronized with the Output Stage signal; (2) protection against loss of a reference voltage; (3) a dead band” associated with the “ON” and “OFF” periods that confers exceptional tolerance to system electrical noise; and (4) a voltage compensation feature with “flat”, “drooping” or “rising” system voltage output characteristic versus system loading. | 10-01-2009 |
