The invention relates to a forest fire early detection system with a terminal, wherein the terminal has a sensor unit, wherein the sensor unit has a first and a second bimetallic signal transmitter, wherein the two bimetallic signal transmitters are designed differently from one another. The invention further relates to a method for detecting forest fires with the method steps of detecting the amount of heat energy from a first bimetallic signal transmitter of a forest fire early detection system, converting the amount of heat energy into a deformation of the bimetal of the first bimetallic signal transmitter, generating a first signal through the deformation of the bimetal of the first bimetallic signal transmitter.

Systems and methods are disclosed for a two lead electronic switch adapted to replace a mechanical switch. In one embodiment, a device is provided that includes a sensor and an electronic circuit having a voltage limiting circuit. The electronic circuit is configured to deactivate/activate the voltage limiting circuit to operate the electronic circuit in a first/second state in response to determining that an output of the sensor is less/more than a threshold voltage. The circuit includes first and second terminals configured to receive a switch voltage used to provide power for the device. The device sets the switch voltage to a first voltage level operative to power the electronic circuit and the sensor while the electronic circuit is operating in the first state and to a second voltage level operative to power the electronic circuit and the sensor while the electronic circuit is operating in the second state.

The present invention relates to the technical field of plugs and sockets for electrical appliances. Disclosed are a surface contact plug and socket, comprising a matching plug and socket; a plug contact piece connected with a plug electric wire is arranged on the lower surface of the plug; and a socket contact piece connected with a socket electric wire is arranged on the upper surface of the socket; when the plug is inserted into the socket, the plug contact piece vertically or obliquely meets the socket contact piece to cause surface contact electrification. The surface contact plug and socket of the present invention employ surface contact between contact pieces, enlarge the contact area and improve current transmission capacity since the plug and socket are of the same size, and therefore the contact is always reliable, and the more the plug and the socket are used, the more reliable the contact is.

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 configuring a control schedule for an environmental control system using a control device is disclosed. The control device has a display and a directional input element such as a rotary dial. The method involves performing a time period configuration process for a sequence of time periods. A time period is added to the control schedule and a representation of the added time period is displayed. In response to directional activation of the directional input element, a duration of the added time period is adjusted, with the representation being updated to indicate the adjusted duration. The adjusted duration is stored in response to a confirmation input signal. The time period configuration process is repeated until it is determined that no more time periods are to be added to the control schedule.
