A power supply control device includes: a power generator that converts energy into power; an environmental sensor that detects a state of an ambient environment; and a controller that controls an operation timing of a functional circuit that operates upon receipt of power supplied from the power generator based on the state of the ambient environment detected by the environmental sensor.

An electrical mains plug having a body formed of an electrically insulating material is described. Two contact pins are arranged parallel to one another and which project out of the body at a first side thereof, and inside the body are connected or can be connected in each case to an electrical conductor which leads out or can be led out of the body at a second side thereof. The thermal bimetallic element is provided as a temperature sensor, said thermal bimetallic element being a constituent part of the thermal bimetallic switch which is associated with at least one of two contact pins. An electrical connection cable suitable therefor and an electrical device connected thereto are also described.

A method of thermal control in a chassis is presented. An example method of thermal control can include each of one or more blades reporting a requested fan blade speed to a CMC controller where the CMC controller performs an auction of the requested fan blade speed, determines a high value and assigning a corresponding active blade, and reporting the high value to the blades. The active blade then provides fan speed alerts while the passive blades provide fan speed alerts only when the new fan speed request exceeds the high value.

A method of controlling an environmental control system, where the environmental control system is configured to operate in accordance with a control schedule, in a scheduled mode of operation. At a control device that is associated with the environmental control system, a user can receive input indicative of a boost mode. In the boost mode, the environmental control system can disregard the control schedule and operate in accordance with a boost setting, with a target temperature. Responsive to the boost mode, further user input may be used to set the target temperature for boost mode. Boost mode can be activated based on the target temperature, and environmental control can be performed based on the target temperature.

The temperature switch includes a housing, an actuator, a switch, and a force buffer situated between the actuator and the switch. The switch is movable between a first and second state in response to imposition and release of an actuating force F.sub.A. The force buffer transmits the actuating force F.sub.A from the actuator to the switch when compressed a first distance in the first direction by extension of the actuator in response to an increase in temperature T.sub.1. At temperature T.sub.1, the force buffer transmits the force F.sub.A to move the switch from the first state to the second state. The actuator retracts a second distance in the second direction in response to a decrease in temperature T.sub.2. At temperature T.sub.2, the force buffer releases the force F.sub.A and the switch moves from the second state to the first state.

An expansion system for temperature detection by means of thermomechanical expansion and movement has an expansion receptacle, an elongate fluid line which is connected in a fluid-conducting manner thereto, and a switching means which is mechanically operatively connected to the expansion receptacle for the purpose of actuation of a switching process of the switching means at a settable actuation point. A working fluid is contained in the expansion receptacle and in the fluid line. Furthermore, an activation material which is formed to change, upon contact with the working fluid or upon mixing with the working fluid, said working fluid with regard to its volume and/or its flowability is contained in the expansion system.

A resettable sensor assembly includes a body having a axis and defining a cavity therein. The body includes a first plurality of threads disposed about the axis. The assembly includes a housing mated to the body and including at least one electrical contact. The assembly further includes a plate. The assembly also includes an actuator element configured for translating the plate along the axis between a first position in which the plate contacts the at least one electrical contact and a second position in which the plate is spaced apart from the at least one electrical contact. The element is formed from a shape memory alloy that is transitionable between an austenite crystallographic phase and a martensite crystallographic phase in response to a thermal activation signal to thereby translate the plate between the first position and the second position.
