| 20090099697 | Power Supply Switch for Dual Powered Thermostat, Power Supply for Dual Powered Thermostat, and Dual Powered Thermostat - A power supply switch for a dual powered thermostat switches the power supply to a dual-powered thermostat with a touch-screen display when a change in primary power supply is detected. The switch switches to an auxiliary power supply. The auxiliary power supply can be a battery. | 04-16-2009 |
| 20090251105 | TEMPERATURE CONTROLLER - A temperature controller is disclosed in the invention, and the temperature controller includes one dry battery, a voltage conversion circuit connected with outputs of the battery and a temperature controller control circuit connected with the voltage conversion circuit. The voltage conversion circuit provides a power supply for the temperature controller control circuit. The temperature controller in the invention requires only one battery as the power supply, so that energies are saved, and the temperature controller is reduced in size and can be mounted more easily. | 10-08-2009 |
| 20100013441 | TEMPERATURE CONTROLLER - A temperature controller is provided, which comprises a control circuit. The temperature controller further comprises a charging circuit and a chargeable battery. The charging circuit functions to charge the chargeable battery and at the same time supply power to the control circuit. In the temperature controller according to the present invention, the chargeable battery is charged by an external power source, and the chargeable battery can be reused, thereby reducing cost of the temperature controller and environmental pollution caused by using alkaline batteries. | 01-21-2010 |
| 20100032181 | Installation construction for electrical box - The present invention discloses an installation construction for an electrical box which comprises a mounting fastener and a mounting aperture on an electrical box; the mounting fastener is of a thin fastener shape with a defined thickness, and is disposed with a construction for securing onto a wall face; the mounting aperture is located on a bottom face of the electrical box, and has a depth dimension which corresponds with the thickness of the mounting fastener, and a transverse cross-sectional shape and dimension which correspond with a transverse cross section of the mounting fastener; an interlocking construction is disposed between the mounting fastener and the mounting aperture, the electrical box can be secured in place by directly inserting the mounting aperture to the mounting fastener. In comparison with the prior arts, the present invention provides an installation construction for an electrical box which requires simply securing a mounting fastener with an area far smaller than that of a mounting bottom plate in the prior art onto a wall face. Conveniently, by means of inserting the electrical box onto the mounting fastener, the electrical box could be secured in place. As the mounting fastener and the electrical box can be directly and accordingly engaged with each other, when the electrical box has to be dismounted, a disengaging action is not first required, thereby simplifying a mounting and dismounting action. | 02-11-2010 |
| 20100038569 | ELECTRIC CONTROL VALVE - An electric control valve provided in the present invention has a valve gate and a control actuator including a middle seat ( | 02-18-2010 |
