Abstract:
An improved electrical connection is provided between terminals (T) mounted in a sensor cap (26) that closes an otherwise open end of a cylindrical EEGR valve body shell (24), and terminals (98, 99) mounted in sockets (100, 102) on a solenoid coil assembly (70) that operates the EEGR valve from an engine electrical control that is connected via a wiring harness connector plug mating with an external plug of sensor cap (26) containing terminals (T). The end portions of terminals (T) that mate with terminals (98, 99) are forked blades having reduced thickness from an adjoining portion, thereby providing greater resilient flexibility for a better and more reliable electrical connection.

Abstract:
전자석 구동회로장치가 개시된다. 전자석 구동회로 장치는 전압출력부, 전자석, 전압제어부, 적어도 하나의 스위치 및 방향제어부를 포함한다. 전압출력부는 구동전압을 출력한다. 전자석은 구동전압이 인가됨에 따라 흐르는 구동전류의 변화에 의해 자성을 발생한다. 전압제어부는 전자석에 의해 발생되는 자성의 레벨이 기준자성레벨이 되도록 전압출력부를 제어한다. 적어도 하나의 스위치는 전자석에 연결되어, 구동전류의 방향이 선택적으로 전환되도록 스위칭한다. 방향제어부는 전자석에 인가될 구동전압의 부호를 결정하고, 결정된 구동전압의 부호에 따라 구동전류의 방향이 전환되도록 적어도 하나의 스위치를 제어한다. 이로 인하여, 전자석을구동하는 전력의 손실을 최소화하여 효율적인 구동이 가능하다
Abstract:
A microrobot assembly system includes a substrate containing conductive traces formed into at least one holding zone and one moving zone, a diamagnetic layer on the substrate, at least two magnetic structures movable across the diamagnetic layer in response to voltages applied to the conductive traces, wherein the holding zone holds one of the magnetic structures and the moving zone allows another of the magnetic structures to attach to the magnetic structure being held. The system may include a plate spaced above the substrate and rails to guide the moving magnetic structures.
Abstract:
Methods and apparatus for automatically coupling stackable modular devices are described. The modular devices may be coupled using electromagnetic forces generated by precisely-timed pulses of electric current through electromagnetic materials that cause a first modular device to screw itself into a second modular device. The modular devices may exchange data through electrical or optical connections after coupling. A method includes detecting that a second modular device is proximately and coaxially located to a first modular device, activating a plurality of electromagnetic elements in an annular electromagnetic array according to a timed sequence, each electromagnetic element being activated at a different time than the other electromagnetic elements in the plurality of electromagnetic elements, detecting that the second modular device is communicatively coupled with the first modular device, and deactivating the plurality of electromagnetic elements after detecting that the second modular device is communicatively coupled with the first modular device.
