Abstract: A lighting fixture includes a solid-state lighting source, such as an LED light source. A control module of the lighting fixture uses temperature sensing circuitry to determine a relative ambient temperature. When the ambient temperature is above a defined ambient temperature threshold, a drive signal is provided to the solid-state light source at a target drive level that corresponds to a normal light output level. When the ambient temperature is below the ambient temperature threshold, the drive signal is provided to the solid-state light source at a reduced drive level, which is lower than the target drive level.

Abstract: A sensor for sensing one or more properties of a vehicle fluid has a tuning fork resonator adapted to contact the fluid. The tuning fork resonator comprises two tines and is operable to oscillate so that the two tines move in opposite phase at a frequency of less than 1 MHz while contacting the fluid to generate a resonator response indicative of one or more properties of the fluid. In another aspect, a sensor includes a substrate and a flexural resonator on the substrate and adapted to contact the fluid. Circuitry for operation of the resonator is on the substrate. The resonator is adapted to receive an input signal and to oscillate while contacting the fluid to generate a resonator response indicative of one or more properties of the fluid. One suitable application for the invention is monitoring the condition of a vehicle engine oil.

Abstract: Fluid monitoring methods, systems and apparatus are disclosed, including a portable subassembly that is in electrical communication with a sensor in contact with the fluid being monitred. Preferred embodiments for the sensor include one or more flexural resonator sensing elements. In preferred embodiments the sensor subassembly is ported to multiple fluidic systems to monitor the fluid properties in an effecient manner.
