A control circuit for a lighting system allows analog control over a first range of illumination intensities in which the intensity of the illumination source varies in proportion to the voltage level of the control signal. The circuit provides for improved dimming and color mixing capability by allowing pulse width or frequency modulation control in addition to analog control over a second range of illumination intensities.

A method of handling an incoming call during an operational mode of a wireless communications device is provided. With the operational mode activated, an incoming call is received at the wireless communications device on a control channel of the wireless communications system. The source of the incoming call is identified, typically by activating caller ID circuitry resident within the wireless communications device to identify a phone number of the source of the incoming call. One of a plurality of pre-recorded messages is then selected either manually or automatically to play back to the source of the incoming call. The plurality of pre-recorded messages are stored at a voice message mailbox in the wireless communications system allocated to the wireless communications device. The incoming call is then diverted, without completing the call and switching to a traffic channel, to the voice message mailbox of the wireless communications device and the selected pre-recorded messages is played back for the source of the incoming call.

A system for and method of estimating the state-of-age of a secondary cell utilizing an adaptive group filter algorithm, includes battery current, voltage, and temperature sensors, a communication device, and a controller communicatively coupled to the sensors and device, configured to filter data by analyzing only sample data points from instantaneous charge or discharge events, selecting only a sample of n instantaneous points for further regression, including n/2 charge event points and n/2 discharge event points, and separately averaging the charge and discharge event points, and further configured to determine the state-of-age by determining a resistance slope based on the rate of current and voltage change between the averages of the points, and matching the slope to a calibrated scalar or relational database.

A control/driver circuit produces variable current output for a lighting system providing improved dimming and color-mixing capability by allowing digital modulation control in addition to analog control over a range of illumination intensities. The circuit and method described is preferably adapted to higher current applications such as LED lighting systems using high-power LEDs. The output current of the circuit varies in proportion to the voltage level of an analog control signal, and additionally in proportion to the relative duty cycle of a digital pulsed control input.

A physical cache memory that is divided into one or more virtual segments using multiple circuits to decode addresses is provided. An address mapping and an address decoder is selected for each virtual segment. The address mapping comprises two or more address bits as set indexes for the virtual segment and the selected address bits are different for each virtual segment. A cache address decoder is provided for each virtual segment to enhance execution performance of programs or to protect against the side channel attack. Each physical cache address decoder comprises an address mask register to extract the selected address bits to locate objects in the virtual segment. The foregoing can be implemented as a method or apparatus for protecting against a side channel attack.

A method and apparatus is disclosed for acquiring and processing parameters used to adjust and tune a controller used, for example, to govern and compensate for motion, including vibrations and disturbances, in a physical system, such as a piece of manufacturing equipment. The method and apparatus may also be used to control, for example, a robot or other spatially dependent machine. The method and apparatus may comprise systems and methods for generating a controller, and for controlling motion in a physical system or apparatus.

A diverter valve controls input of two different extruded materials to a mold. A valve body has an axially extending opening, and a valve piston is axially movable in the opening between first and second positions. The body defines a first inlet for receiving a first material, and a second inlet for receiving a second material with first and second outlets opposite the inlets. A first flushing channel communicates with the first inlet and end ports, a second flushing channel communicates with the second inlet and end ports, and a third flushing channel opposite the first two communicates with the second outlet and includes a plurality of ports, with all the ports, inlets and outlets open to the axial opening. The piston has first and second through channels and first and second cross-over channels, each with inlet side and outlet side ports. In the first position, the first through channel connects the first inlet with the first outlet and the second through channel connects the second inlet with the second outlet, the valve piston blocks the end ports of the first flushing channel, and the first and second cross-over channels connect the second and third flushing channels to allow flow of material therein from the second inlet. In the second position, the first cross-over channel connects the first inlet with the second outlet and the second cross-over channel connects the second inlet with the first outlet, the valve piston blocks the end ports of the first flushing channel, and the first and second through channels connect the first and third flushing channels to allow flow of material therein from the first inlet.

A method and system for guiding a vehicle through a tunnel or other space. A linear beam of light is projected along a certain path through the space. As the vehicle travels into the space, the linear beam is shined upon the vehicle. Visually aligning an indicator on the vehicle with the linear beam of light indicates to the driver that the vehicle is traveling directly down the center of the path. The alignment occurs by the driver making manual adjustments of the vehicle's direction by turning wheels of the vehicle.

A piezoelectric transducer driving circuit has a main oscillator stage, a buffer circuit, and a voltage-doubling circuit. The main oscillator stage includes a frequency-swept signal generator that can be configured to provide different outputs to the buffers, which in turn provide the output to the voltage-doubling circuit, which supplies the piezoelectric transducer, causing it to mechanically deform and produce audible sounds of different types.

A method of casting parts with gray iron includes the steps of providing molten gray iron metal with controlled carbon, silicon, phosphorous, sulfur, manganese and chromium content; alloying said molten gray iron metal, prior to pouring, with tin to a total tin content of about 0.05% to about 0.10%; inoculating said molten tin-alloyed gray iron metal, prior to pouring, with a gray iron inoculant to an additional silicon addition of from about 0.10% to about 0.12%; and casting the gray iron part from said molten, tin-alloyed inoculated gray iron metal as son as possible after said inoculation.

A paddle is provided with lighting devices in the blade of the paddle.

Provided is a novel Nanofiltration-DiaNanofiltration (NF-DiaNF) system and method for extracting divalent ions from saline water (e.g., seawater) to produce solutions rich in divalent ions (in particular Mg2+, Ca2+ and SO42−), while minimizing the concentrations of undesirable species (e.g., Cl−, Br−, B and Na+). The solutions may be added to water (e.g., desalinated, soft, drinking or irrigation water) to enrich the water with divalent ions, thereby improving its quality.

A filter system for filtering a fluid is provided with a filter housing and a filter element arranged in the filter housing. The filter element has a glass fiber filter medium. A sintered body is arranged fluidically downstream of the glass fiber filter medium for retaining constituents of the glass fiber filter medium entrained in a fluid to be filtered. A pore size of the sintered body is greater than a cross-section of the constituents of the glass fiber filter medium.
