Described is a rotary coupling that includes a pair of coupling bodies having parallel (preferably coincident) rotation axes, two cylindrical elements and a preload mechanism. A gap is provided between surfaces on the first and second coupling bodies. The first cylindrical element is disposed on the first coupling body and has a first cylinder axis, and the second cylindrical element is disposed on the second coupling body adjacent to the first cylindrical element and has a second cylinder axis that is perpendicular to the first cylinder axis. The preload mechanism imparts a force to each of the first and second coupling bodies and thereby preloads the first and second cylindrical elements against each other at a point of contact. One example of the preload mechanism includes a pair of magnets disposed opposite each other across the gap and another example of the preload mechanism includes an air bearing.

An electrical connector including a first connector portion and a second connector portion, and interface electronics for providing an interface between terminals associated with the first and second connector portions and a vehicle bus.

Trailer tow connector assembly

An electrical connector including a first connector portion and a second connector portion. First and second covers are pivotally attached to the body about a common axis for covering the first and second connector portion.

An electrical connector including a first connector portion and a second connector portion. Each of the first and second connector interfaces includes several terminals. At least a portion of the terminals of the first connector interface are electrically coupled to associated ones of the terminals of the second connector interface via a multi-level arrangement.

A capacitive transducer (10) has a housing (12) which receives a variable capacitor (14) in a fluid pressure receiving chamber (12e). A support (20) is received on an annular shoulder (12j) formed in the sidewall (12h) of the housing. The support has inner and outer concentric ring shaped lands (20k, 20l) with the inner ring shaped land engaging the variable capacitor (14) inboard of the outer peripheral edge of the capacitor. A shelf (20d) is formed on the sidewall of the support which receives a first relatively rigid substrate (26a) of a circuit board which has a second relatively rigid substrate (26b) bent through a connecting flexible strip so that the second substrate overlies the first substrate within a circuit receiving chamber (20c). A ratiometric signal conditioning circuit portion 28a and voltage regulating circuit portion 28b are mounted on the circuit board. The voltage regulating circuit is used to convert the transducer into a variable supply/fixed output device and includes a precision voltage regulator (U2) having an input capability of a portion of the range of the variable supply voltage, an NPN transistor (Q1) to provide a variable resistance in the primary current path, a zener diode D3, a current regulating diode (D2) to bias the transistor and the zener diode, a blocking diode (D1) and associated capacitors (C13, C14, C15).
