Abstract: The invention comprises a nail drying aerosol spray that comprises a combination of solvents having different rates of volatility. One of the solvents is dimethyl ether.

Abstract: The present invention relates to a method and a device for detecting the operating state of a vehicle battery. A method according to the invention has the following steps: charging of the battery from a first state of charge (SOC1) to a second state of charge (SOC2), wherein the second state of charge (SOC2) is higher than the first state of charge (SOC1); active discharging of the battery to a third state of charge (SOC3), wherein the third state of charge (SOC3) is lower than the second state of charge (SOC2); and determination of at least one variable, which is characteristic of the operating state of the battery, after the third state of charge (SOC3) has been reached.

Abstract: A method and system for modeling or simulating an application environment so as to evaluate the effect of a selected battery and charger in the application environment. Sensors are used to gather data regarding the energy consumption needs of the application environment over time. Based on the energy needs and/or user-specified application environment parameters, such as a charge schedule, a battery size and type, and a charge return model, an energy transfer profile for the application environment is generated and outputted. The energy transfer profile provides an indication of the state of charge of the battery over time based upon the simulated discharging and charging of the battery in the application environment. The generation of the energy transfer profile takes into account the charging schedule and the incremental change in battery parameters over time.

Abstract: Some aspects of the present invention provide for the downloading of code, including but not limited to peripheral device code, upon the occurrence of predetermined events, sometimes referred to herein as “triggers.” For example, exceeding a predetermined number of errors within a predetermined time may comprise a trigger. Some implementations provide new peripheral device code each time a gaming machine initializes. Some embodiments provide peripheral devices with relatively small (or no) non-volatile memory. A smaller non-volatile memory (as compared to prior art peripheral devices of the same type) may be possible because it is not necessary—and may not be desirable—to retain peripheral device code in non-volatile memory.

Abstract: A pan type concrete mixer in which a plurality of sprayers are inserted in a substantially equl-spaced arrangement in a lid of the pan to extend into the chamber. Each sprayer has a head with two diametrically-opposite jet nozzles. Each head is capable of substantially 360° rotation. Each sprayer is connectable to a pressurized water supply whereby passage of water into each sprayer causes rotation of the respective head and jet discharge of spray from the respective nozzles around the inside of the chamber.

Abstract: A combustion boiler for burning fuel and producing heat to generate steam. A method of minimizing discharging of nitrogen oxides from a combustion boiler comprising the steps of spraying a reducing agent into an overfire air stream and supplying the overfire air stream to the combustion boiler. Vaporizing the sprayed reducing agent at least within about 0.1 seconds of the sprayed reducing agent entering the combustion boiler and reacting the vaporized reducing agent with the nitrogen oxides within the combustion chamber to reduce the nitrogen oxides and minimize discharge of nitrogen oxides from the combustion boiler.

Abstract: An apparatus and method for recharging a rechargeable lead acid battery. The apparatus supplies an overcharge current to the battery during and before completion of recharging of the battery to ameliorate stratification of the battery.

Abstract: A method of operating a voltage reference element such as a zener diode comprises applying at least two current values to the device in respective periods of time one said value being such as to provide desired reference voltage characteristics of the device and the other being such that the average current during both periods provides a selected power dissipation to set a required temperature of operation of the device.

Abstract: A method by which a pair of communicating network equipment drivers can determine if the equipment they control such as a network adapter or a switch port are directly connected by a single network cable, is applicable to network protocols which include a link active signaling technique as part of the physical layer specification. The method includes determining whether the link is in a first state in which there is only one device coupled to the link without intervening devices which are members of a particular class, or in a second state in which there may be more than one device coupled to the link without intervening devices which are members of the particular class. If the link is in the first state, then a physical layer test involving the physical layer link active signaling mechanism is executed to ensure that the responding device is coupled to the same link without intervening devices that are not members of the particular class.
