摘要： A temperature sensor for radiant heating units with a heating coil disposed in a cup includes a tube with a first end connected to a housing of a switch with a movable contact cooperating with stationery contacts in the housing. A two-section rod, which extends into the housing of the switch and operates the movable contact, is supported inside the tube. The tube and the rod have different thermal expansion coefficients. To prevent a shift in the switching point, the section of the rod that operates the contact terminates outside the hollow space of the cup, and the temperature-induced length changes of this section and of the housing are matched to each other.

摘要： An method and apparatus for dampening microelectromechanical system (MEMS) devices is disclosed. A typical method or apparatus embodiment of the invention includes a microelectromechanical system (MEMS) device including an actuator and a movable element and having a frequency response. A shape memory alloy (SMA) material is applied to the movable element of the MEMS device to provide passive damping to the frequency response of the MEMS device. The applied SMA material typically provides no actuation of the MEMS device. A chemical vapor deposition (CVD) process can be used to apply the SMA material.

摘要： A temperature sensitive circuit breaker includes two contacts electrically mounted on a circuit board and an insulating pivot seat attached to the circuit board between the two contacts. A lever has a first end pivotally connected to the pivot seat and connected to one of the contacts, and a second end electrically connected to the other contact. A non-metallic expansive rod is mounted on the circuit board below the lever to push the lever upward to make the second end of lever separate from the contact when a high temperature on the circuit board is transferred to the expansive rod. The breaking member causes a high temperature to melt itself when a current passes through the breaking member to open a circuit on the circuit board.

摘要： The present invention provides actuators and actuator devices that take advantage of a strain gradient variation of an actuator element between a first phase and a second phase. The actuator elements can be positioned in any type of shape. For instance, the actuator element in the first phase can be any type of curved, non-linear or irregular shape as long as a strain gradient along a cross-section of the actuator element can be established. The actuator element in the second phase is positioned in a different shape when compared to the first phase as long as it is in a direction to minimize the strain gradient. Different actions can be generated such as a rotary movement, a linear movement, an expanding movement, or a combined linear and rotary movement. The actuator element could also be configured to generate a linear movement by combining contraction and strain gradient variation.
