A device has built-in inductive load testing capabilities. The device includes a device housing, an inductive load disposed within the device housing; and test circuitry disposed within the device housing. The test circuitry is constructed and arranged to effectuate application of a modulated test signal to the inductive load, and obtain a result signal in response to the application of the modulated test signal to the inductive load. The test circuitry is further constructed and arranged to generate an output signal indicating that the inductive load is in one of (i) a shorted inductive load state, (ii) a normal inductive load state, and (iii) an abnormally high inductive load state, based on the result signal. Such test circuitry is well-suited for testing a variety of devices having inductors/coils which are susceptible to defects (e. g. , a solenoid, a motor winding, various actuator components, etc. ).

A method and a system for determining analyte content in a fluid in a treatment apparatus. The method comprises positioning a device for treatment in a treatment apparatus. A surface of the device is contacted with a fluid. An analyte content in the fluid is determined based on an electromagnetic property of the fluid following contacting the surface of the device with the fluid. More specifically, an electromagnetic property is measured. The measuring comprises emitting electromagnetic radiation into the fluid in the treatment apparatus and detecting electromagnetic radiation from the fluid. In another aspect, a system comprising a treatment apparatus and a detector for determining the analyte content in the fluid in the treatment apparatus is provided.

An electrical connector assembly includes a connector body that is formed of a first dielectric material defining a terminal cavity configured to receive an electrical terminal. The connector body defines a chamber that is separate from the terminal cavity. The chamber contains a second dielectric material that has a lower dielectric constant property than the first dielectric material, such as air. The connector body may be formed by as additive manufacturing process, such as 3D printing, stereolithography, digital light processing, fused deposition modeling, fused filament fabrication, selective laser sintering, selecting heat sintering, multi-jet modeling, multi-jet fusion, electronic beam melting, and laminated object manufacturing.

A motor system includes a motor including two linear Hall sensors configured to output analog signals, and a controller configured to control the motor. The controller is operable to monitor the analog signals output from the two linear Hall sensors, determine a plurality of auxiliary signals based on the analog signals, and determine a motor position based on the plurality of auxiliary signals.
