Abstract: Aqueous coating compositions containing (1) a first polymer containing reactive functional groups with a selected level of carboxylic acid functionality and (2) a polyfunctional crosslinker agent containing functional groups that are reactive with appropriate functional groups of the first polymer, are disclosed. The two-component polymer compositions provide a combination of durability and ready removability of the final coating after curing. Two-component polymer compositions based on the first polymer containing hydroxyl functionality in addition to carboxylic acid functionality and use of a polyisocyanate as the polyfunctional crosslinker agent are especially useful as floor polish compositions.

Abstract: A system and a method for visual, electronic communication and/or entertainment purposes, displaying a lightshow, which can, if desired, represent selected information/events have been achieved. Said lightshow/information is displayed using one or more LED modules comprising more than one, usually three, LEDs emitting each light in different primary colors of a color space. Thus a lightshow/information/events can be visually displayed using a multitude of colors, different brightness, by flashing, by activation of specific positions, and by ON/OFF intervals. Said LED modules are controlled by a circuit comprising a LED driver unit, controlling the light intensity of each LED, a sequencer to control said LED drivers, and a memory to store the patterns for the illumination, the sequence and the brightness. The LEDs can be preferably addressed in a multiplexing mode, thus the connection between the LED drivers and the LEDs can be simplified.

Abstract: A CCFL can exhibit different strike characteristics depending on age and temperature. A CCFL in a direct driven CCFL circuit that is difficult to strike can appear to be malfunctioning using a standard start up operation. A controlled start up allows additional opportunities for a slow striking CCFL to strike. In one embodiment, the CCFL of the direct drive CCFL circuit can be initially driven at a switching frequency substantially different than a resonant frequency. Based on certain conditions, the switching frequency can subsequently be allowed to approach resonant frequency in a controlled manner. If the driving frequency reaches the resonant frequency of the CCFL during a set time period, then the CCFL can enter into steady state operation. At this point, the same conditions can be monitored to identify fault conditions in the direct drive CCFL circuit.

Abstract: Methods, systems, and computer program products can be provided for evaluating a risk of the occurrence of cardiac arrhythmias in a heart. The system can include at least one sensing electrode and a controller. The sensing electrode can be configured to sense electrical signals from a heart over a range of heart rates.

Abstract: A massive choke coil [e.g. exceeding about three henries, with at least a thousand turns and a relatively low internal resistance of about eleven ohms] placed in parallel with the A/C line, that is, preferably across the A/C line's “hot” and “common” lines, quenching the reflected signal (or back emf) that is developed when any power amplifier or other load places its demands upon the incoming A/C power line. Due to its electromagnetic characteristics, the choke tends to provide a momentary high current source of energy when needed by, e.g., a power amplifier (or other appropriate load) when transient demand is called for. The parallel choke approach tends to have a reversing effect on this signal, at least substantially reducing its presence on the A/C line, providing a greatly enhanced A/C power line signal quality, without which the otherwise untreated signals are able to modulate the A/C line.

Abstract: A choke coil [e.g exceeding about three (3) henries] placed in parallel with the A/C line, that is, preferably across the A/C line's “hot” and “common” lines, quenching the reflected signal (or back emf) that is developed when any power amplifier or other load places it's demands upon the incoming A/C power line. Due to its electromagnetic characteristics, the choke tends to provide a momentary high current source of energy when needed by, e.g., a power amplifier (or other appropriate load) when transient demand is called for. The invention's parallel choke approach, due to the fact that it must be magnetically charged by electricity [either from the A/C line or back electromotive force (emf) from it's load] tends to have a reversing effect on this signal, preventing, eliminating or at least substantially reducing it's presence on the A/C line, thereby providing a greatly enhanced A/C power line signal quality for the load.

Abstract: A motor vehicle rear light assembly designed to be used in addition to the conventional vehicle brake lights includes a housing adapted to be mounted at the rear of a vehicle and having at least three compartments each containing a light source such as one or more light bulbs. The light sources are operated by a suitable control circuit, which may be connected to the vehicle brake lighting system, so that the central light source is switched on to burn continuously as long as the brakes are applied and the outer two light sources flash alternately on and off a predetermined number of times as soon as the brakes are applied and then burn continuously until the brakes are released. Mounting brackets which are rotatably mounted on the housing are used to mount the housing on a vehicle in the desired orientation.

Abstract: A trimmer potentiometer or like variable resistor, which is of the kind having a worm 21 driving an elastomeric worm wheel 10 carrying a wiper contact to slide on an arcuate resistance element, has the gear teeth formed on circumferentially-spaced rim sections 23, 24, 25 projecting cantileverwise from an axially thick unbroken rim 10b of a radial flange on the main body 10c of the wheel, some sections 23 having only a few gear teeth and being separated by sections 24, 25 having larger numbers of gear teeth. The extent of rotation of the wheel 10 is limited to less than 360.degree. and the sections 23 with few teeth are arranged to be in mesh with the worm at the limits of wheel rotation so as to give a de-clutching effect by inward deflection of these sections on over rotation of the worm.
