摘要： An automotive head restraint apparatus includes a housing having a padded and upholstered exterior, the housing being rotatable about a lateral support tube that supports a lock plate having a lobe extending radially with a detent slot extending therein. A latch finger extends from a pivotable lock lever plate to releasably engage in the detent slot to latch the housing in the deployed position. A pull rod is secured to the lock lever plate, and is connected to a release lever arm at its other end. A shape memory alloy (SMA) wire loop is passed about a drive pulley that is supported by a reciprocally translatable slide. A drive arm extends from the slide to impinge on the release lever and raise the pull rod when the SMA wire loop is energized and contracted, thereby releasing the latch finger to rotate the housing to the retracted position.

摘要： An inflation device is provided including a shell, a pin, a restraining element, and a moveable element. The shell is adapted to be coupled to an inflation canister. The pin is positioned within the shell. The pin is adapted to open a seal of the inflation canister. The restraining element is positioned within the shell. The moveable element includes a shape memory alloy. The moveable element is moveable from a first position to a second position responsive to electrical energy sent to the moveable element. While the moveable element is in the first position, the restraining element is secured within the shell to restrain the pin from opening the seal of the inflation canister. While the moveable element is in the second position, the pin is releasable to open the seal of the inflation canister.

摘要： A method and apparatus for preventing the unintended activation of SMA devices by ambient temperatures that exceed the phase transition temperature of the SMA material itself. In one embodiment a passive actuator is coupled to an active actuator, each having identical arrangements of SMA wire, but connected in opposite directions to compensate for temperature drift that is not due to powered heating. A second embodiment consists of a passive SMA wire connected to a latch/release mechanism allowing the actuator itself to move rather than moving the load. In a third embodiment the passive wire is connected to a load coupling, so that the load itself is disconnected from the actuator when the passive wire reaches the phase transition temperature. The passive wire may be made of a lower-temperature wire than the active wires, so that the release action occurs long before the active wire begins to be moved by ambient temperature.
摘要翻译： 一种用于通过超过SMA材料本身的相变温度的环境温度来防止SMA器件意外激活的方法和装置。 在一个实施例中，无源致动器耦合到主动致动器，每个主动致动器具有相同的SMA线排列，但是以相反方向连接以补偿不是由于加热加热引起的温度漂移。 第二实施例包括连接到闩锁/释放机构的被动SMA线，允许致动器本身移动而不是移动负载。 在第三实施例中，无源线连接到负载耦合，使得当无源线达到相变温度时，负载本身与致动器断开连接。 无源线可以由比有源线更低温的导线制成，使得释放动作在有源线开始被环境温度移动之前很长时间发生。

摘要： An inflation device is provided including a shell, a pin, a restraining element, and a barrier. The shell may be coupled to an inflation canister. The pin is positioned within the shell in order to open a seal of the inflation canister. The restraining element is positioned within the shell and is positioned to prevent the pin from opening the seal of the inflation canister. The restraining element is dissolvable. The barrier is positioned within the shell. The barrier includes a fluid resistant skin and a heating element coupled to the fluid resistant skin. The heating element may open a portion of the barrier responsive to an electrical current running through the heating element.

摘要： Actuators that employs a shape memory alloy component as the driving element include linear and rotational devices. An Intrinsic Return Means (IRM) may be imparted to the SMA actuator, thereby reducing the use of a spring return mechanism. The rotational actuator may include a cylindrical bobbin with a helical groove to receive an SMA wire. A number of turns may be placed in a small length of bobbin to amplify the rotational excursion. In another rotational actuator, a plurality of narrow, coaxial rings are provided, the rings being nested in close concentric fit or stacked in side-by-side fashion. Each ring is provided with a groove extending thereabout to receive an SMA wire and contraction of the wire causes each ring to rotate with respect to the adjacent ring. In an embodiment for linear actuation, the invention provides a bar-like component having SMA wires joined between bars. The invention includes a lost motion coupling to join two counter-acting SMA stroke amplification devices, whether linear or rotational.

摘要： A magnetomotive device has an embedded electromagnetic coil formed of multiple printed conductor segments on multiple lamina of a multilayer PCB. A shaft extends through an opening in the PCB, and a permanent magnet with axially opposed poles is secured to the shaft. Energizing the embedded electromagnet generates a magnetic field that attracts or repels the permanent magnet, driving the shaft to do useful work. A pair of embedded PCB coils may be employed, the shaft extending through both coils with the permanent magnet disposed therebetween, and the coils energized so that one repels the permanent magnet while the other attracts it, and the shaft may be driven reversibly to do useful work.

摘要： A device for limiting the intrusion of a shower curtain into a shower enclosure includes a clamp portion for releasably engaging the shower curtain rod, and an tail portion depending from the clamp portion for impinging on the shower curtain and urging it outwardly. The clamp includes an inverted U configuration adapted to extend about the curtain rod. The U-configuration includes one leg that is joined integrally to the tail portion, and the other leg is provided with a detent tip. A detent lever extends from the tail portion proximate to the detent tip, and includes an array of closely spaced detent teeth adapted to engage the detent tip. The detent lever is resiliently biased toward the detent tip, so that the tip remains engaged with the teeth unless otherwise disturbed. The two legs of the clamp may be squeezed together to engage the curtain rod frictionally to immobilize the device on the curtain rod, and the device will remain in this disposition until released. The tail portion may comprise an inverted T configuration to engage a wide portion of shower curtain and spread the force of impingement thereabout.
