Abstract: Method and apparatus to control LED brightness are disclosed. An example method includes receiving a dimmer control signal; determining a cutoff point of the dimmer control signal; determining the position of a rising edge signal within the dimmer control signal; determining if the rising edge signal occurred before the cutoff point; and outputting an LED brightness signal indicating full brightness when the rising edge signal occurred before the cutoff point, and indicating a scaled brightness when the rising edge signal did not occur before the cutoff point.

Abstract: The disclosed principles provide for a digital industrial network and related method of maintaining and operating a system. An industrial network constructed according to the disclosed principles combines both the control/data signals used with smart control devices and operating power for those devices in one industrial network hybrid cable. In one embodiment, an industrial network comprises smart control devices for maintaining and operating a system, and hybrid cabling connecting the smart control devices in a daisy-chain. In addition, in such an industrial network, the cabling is configured to transmit control/data signals and operating power for the smart control devices along the daisy-chain.

Abstract: A handheld massage device has a body including a handle portion and a head portion forming a socket in which a roller ball is removably received. The user can provide increased pressure and can better control a motion during a massage by way of the device. A rolling aspect of the roller ball provides a distinctive massage, especially when a ball of a predetermined size, material, and/or other physical characteristics is used in the device. The massage device may include a set of roller balls, and the method may include selecting a roller ball from the set based on one or more desired characteristic and/or associated therapeutic property to impart a particular healing or other benefit to the subject person.

Abstract: Decontamination systems and methods are disclosed. In one embodiment, a system comprises a first adsorption/desorption subsystem that is configured to receive a contaminated gaseous solution and remove substantially all of the contaminants from the contaminated gaseous solution during an adsorption cycle, while a second subsystem is configured to purge captured contaminants during a desorption cycle. An evacuator is configured to drive potentially flammable gas compositions from the subsystem operating in a desorption cycle back into the system such that potentially flammable gas compositions are purged from the subsystem operating in the desorption cycle at the beginning of the desorption cycle. A heat source is configured to heat contaminants adsorbed in the adsorption/desorption subsystems to remove the contaminants from the adsorption/desorption subsystems in a gaseous state during their respective desorption cycle.
