A dimmer control system has a communication control loop that connects a master unit in series with a plurality of remote units, and it is superimposed in series on the dimmer load line so as to allow two-way communication between the master unit and remote units without affecting the operation of the load. Communications from the master to the remote units are encoded in loop current fluctuations, whereas communications from any remote to the master unit are encoded in loop voltage fluctuations. The master unit has a switched power supply, for use during normal LOAD ON operation, in tandem with a capacitive power supply, for use during LOAD OFF operation of the control units so as to minimize hum. The master unit power supply circuit provides an output rail voltage comprised of a reference voltage for the load superimposed with a control loop voltage for the voltage drop across the series-connected remote units. The master unit has a POWER OFF detection circuit and a non-volatile memory for storing system status information, so that when power is restored, the system can be restored to its former power level. The switch units are formed with a cover frame mounting a switch plate on a hinge axis allowing ON / OFF movement of an opposing side thereof. An array of LED light pipes is mounted in the switch plate aligned with the hinge axis, in order to minimize displacement of the light pipes during actuator movement.

A re-fueling station is provided for selectively dispensing fuel in the form of liquefied gas or compressed gas. The re-fueling station comprises a storage tank for storing liquefied gas; a positive displacement fuel pump operable to draw fuel from the storage tank and discharge fuel to a flow diverter, which is operable to selectively direct fuel through one of a first outlet or a second outlet; and conduits through which fuel may flow from the first outlet to a heat exchanger and then to a first dispenser for dispensing compressed gas, or from the second outlet to a second dispenser for dispensing liquefied gas. A method is provided comprising operating the fuel pump in a low speed mode when fuel is directed to the first dispenser and operating the fuel pump in a high speed mode when fuel is directed to the second dispenser.

A MEMS device having a movable mirror pixel supported on a substrate and coupled to a motion actuator so as to enable rotation of the mirror pixel about an axis lying within the mirror plane. In one embodiment, the motion actuator has a movable electrode, on which the mirror pixel is mounted. The movable electrode is supported on the substrate by a pair of upright springs, each having two parallel segments joined at one end and disjoint at the other end. One disjoint segment end is coupled to the substrate, while the other disjoint segment end is coupled to the movable electrode. The end of the upright spring corresponding to the joined segment ends points away from the substrate such that (i) the spring body protrudes through a narrow slot in the mirror pixel and (ii) the mirror plane lies at about the mid-point of the spring.

A monitoring device includes a biasing element having opposite first and second end portions, an earbud attached to the biasing element first end portion, and a sensing element attached to the biasing element second end portion. The earbud has a first mass, and the sensing element has a second mass that is less than the first mass. The biasing element is configured to urge the sensing element into contact with a portion of the ear when the earbud is inserted into the ear. The biasing element decouples motion of the earbud from the sensing element. The sensing element includes at least one energy emitter configured to direct energy at a target region of the ear and at least one detector configured to detect an energy response signal from the target region or a region adjacent the target region.

A hybrid input differential engine system comprising a planetary gear set. Preferably, an ICE is connected to the planet gear carrier, the output shaft is connected to the ring gear, and the sun gear is connected to a supercharger / expander and an electric or hydraulic motor / generator. As engine torque increases, the supercharger speeds up, increasing torque still further, enabling a small displacement engine to have very high torque at low RPM. In cruise conditions, the sun gear direction is reversed by the motor / generator, causing the supercharger to act as an expander for efficiently throttling the engine. The motor / generator modulates the speed / torque relationships between the engine and the supercharger / expander. A second motor / generator may be used on the output shaft. The electric machines and electric storage may be downsized because less electrical power is needed for the operation of the system.

A vehicle steering system is provided with a primary steering system, a backup steering system and a control system that switches from the primary steering system to the backup steering system when a defect is determined in the primary steering system such as a defeat in a steering reaction force actuator. The vehicle steering system has a pair of clutches that mechanically disconnect the steering wheel from the steerable vehicle wheels in normal situations, and connect them when the steering reaction force actuator is determined to be defective. The control system has a steering malfunction detection section that detects a malfunction in the steering reaction force actuator, and a steering control limiting section that limits the control commands to the steering gear unit actuator from when the steering reaction force actuator is determined to be malfunctioning to when both the clutches are connected.

In a magnet-exciting rotating electric machine, a magnetic field pole part opposing an armature is composed to be divided into a surface magnetic pole part and a magnetic excitation part so as to be capable of being relatively displaced. The magnetic excitation part supplies a magnetic flux to a magnetic salient pole. The magnetic flux from the field magnet is divided into a main magnetic flux pathway that circulates through the armature side and a bypass magnetic flux pathway that does not pass through the armature, and thereby, the magnetic flux of the main magnetic flux pathway is changed. The magnetic resistances of the main magnetic flux pathway and the bypass magnetic flux pathway are composed so that total magnetic flux amount from the field magnet is maintained constant, and then a magnetic force preventing the relative displacement is maintained small.

An object of the present invention is to provide a plug / socket assembly in which the plug will never pull out of the socket even if an excessive pull-out force is applied to the plug. A plug / socket assembly (10) comprises a plug (20) and a socket (30) for receiving and fixing the plug (20) therein. The socket (30) includes a socket main body (31) having a plug insertion hole (311), balls (32) which are provided with the socket main body (31) in a radially displaceable manner with respect to the plug insertion hole (311), a sleeve (33) which is mounted over the outer surface of the socket main body (31) and is displaceable along the axial direction of the plug insertion hole (311), and a compression spring (34) for urging the sleeve (33) along the axial direction toward the inlet port (313) of the plug insertion hole. The inner surface of the sleeve is provided with a slide surface (332). The slide surface has first to fourth regions (P1-P4). The fourth region (P4) is shaped such that with an external pull-out force being applied to the plug, even if the balls apply a radially outward force to the slide surface, no leftward force to push back the sleeve will be produced.
