Abstract: A sensor assembly includes a fastener body extending from a fastener end to an opposite sensor end along an elongation direction. The sensor end is shaped to be inserted into a sensor port of an air dryer. A sensor substrate includes one or more conductive bodies protruding from the sensor substrate and one or more first conductive pathways coupled with the one or more conductive bodies. The sensor assembly also includes a sensor coupled with the sensor substrate and conductively coupled with the one or more conductive bodies by the one or more first conductive pathways. The sensor is configured to sense a humidity of air flowing through the air dryer. The one or more conductive bodies of the sensor substrate are positioned to engage one or more arcuate or annular conductive pathways in the air dryer in different rotational positions of the fastener body relative to the air dryer.

Abstract: Methods for pump-probe spectroscopy are provided. In an embodiment, such a method comprises directing pump light having a frequency ?pump at a location in a sample to excite a transition between two quantum states of a target entity in the sample, directing probe light at the location to generate a coherent output signal having a frequency ?output and a wavevector koutput, and detecting the output signal as the probe light is scanned over a range of frequencies. In the method, either the transition excited by the pump light is a multiphoton transition corresponding to a frequency difference of n*?pump, wherein n?2; or the probe light is a set of m coherent light pulses, each coherent light pulse having a frequency ?m and a wavevector km, wherein m?2; or both. Systems for carrying out the methods are also provided.

Abstract: A solid fragrance carrier comprising a fragrance-containing polymeric matrix adhesively bonded to a filter or filter bag for filtering an air stream in a vacuum cleaner for providing a fragranced scent to air exhausted from the vacuum cleaner.

Abstract: A method is set forth for providing for the integration of gaming functions and system functions into a gaming device of the type having a video touch screen display. The method includes configuring a platform for the gaming device to have at least a first processor for real time processing of hardware tasks and game logic processes and a second processor for processing system logic and game and system information display processes. At least one first processor and second processor are arranged to control said display to display a gaming interface for viewing a wagering game for play by a player and the second processor is configured to display a systems interface into said gaming interface to display non-game system information from said system-based information signals. The systems logic processes are kept separate from said game logic processes. In various embodiments the method includes displaying a system interface when a player or employee inserts a card into a card reader.

Abstract: A system for cleaning contaminants from a body of water includes a dam that restricts a flow of water in the body of water. The system also includes a generator that generates electric power from the body of water, and one or more electrodes that induce an electrocoagulation current upstream of the dam. A filter press then removes contaminants that are precipitated from the water of the body of water by the electrocoagulation current.

Abstract: A vacuum cleaner is provided with a necked-down suction channel formed in a housing adapted for movement over a surface to be cleaned. The housing further includes a suction nozzle and an agitator chamber. The necked-down suction channel has a height that is less than the height of the agitator chamber.

Abstract: A lubrication system for lubricating at least one movable machine component includes a lubricant reservoir containing a lubricant and a fluid line fluidly coupled with the reservoir and having an outlet for dispensing the lubricant on or within the machine component. A valve selectively permits lubricant flow through the fluid line so as to dispense a quantity of lubricant through the fluid line outlet. A sensor senses a property of the machine component or the quantity of lubricant. A control is coupled with the sensor and with the valve, the control being configured to receive information from the sensor, to determine an estimated period of effectiveness of the quantity of lubricant using the sensor information, and to operate the valve based on the estimated lubricant effectiveness period so as to dispense another quantity of lubricant on or within the machine component.
