    Abstract: A universal remote control system is disclosed. The universal remote control includes a receiver that has a wireless signal receiver unit, an electric motor that drives a mechanical arm and a microprocessor. When the receiver receives a control signal from a wireless signal transmitter, the microprocessor will energize the motor which drives the mechanical arm toward a pushbutton switch of a controlled device, such as a garage door opener, and depresses the push button, therefore activating the garage door opener. A feedback signal, for example, from the mechanical arm or the motor, may be provided to the microprocessor to inform the microprocessor when the pushbutton switch is sufficiently depressed and is in an engaged state. When the switch is in the engaged state, the motor will reverse its direction, causing the mechanical arm to raise and move back to a standby position.

  • Patent number: 8507818
    Abstract: Disclosed is a push switch device. Since a push button is pressed to relatively rotate first and second pressing members in opposite directions and a push direction conversion unit converts the relative rotation of the first and second pressing members into a push movement in a switching direction, a pressing projection of the first pressing member can accurately vertically press an apex of a movable terminal. Therefore, a sense of click when the movable terminal is resiliently deformed and recovered can be maintained well, and a slide friction generated between the movable terminal and the pressing projection of the first pressing member can be minimized, preventing decrease in sense of operation and reduction in lifespan of parts due to the friction. In addition, an operation sense of the push button can be improved because straightness of the push button can be improved and there is no additional repulsion, except the repulsion by the resilient deformation of the movable terminal.

  • Patent number: 8492668
    Abstract: The invention relates to an emergency switch that includes a body receiving a mobile member capable of translation and capable, under the effect of an axial pressure through a mushroom member, of moving from an extended position into a retracted position. Each of the positions are indexed by a blocking device capable of interaction with an extended position notch and with a retracted position notch, the position change being managed by a guide. The body fixedly includes, in the inside thereof, a concentric bushing in which the mobile member is capable of axially moving and which includes a portion of the guide while the mobile member includes the other portion. The blocking device is made in the shape of a piece of material flexibly and elastically attached to the rest of the bushing via a blade.

  • Patent number: 8431850
    Abstract: A button structure includes an installation assembly, a slidable member, a pressable member, and a first resilient member and a second resilient member. The slidable member is slidably attached to the installation assembly. A pressable portion is formed on the slidable member. The pressable member is pivotably mounted to the installation assembly. A pressable cantilever extends from the pressable member. A guide portion protrudes from the pressable cantilever and abuts against the pressable portion. When the slidable member is pushed to deform the first resilient member, the pressable portion presses the guide portion to urge the pressable member to pivot. Thus the second resilient member is deformed, and the pressable cantilever pushes the button to power on or off the electronic device. When the slidable member is released, the first and second resilient members are restored to respectively force the slidable member and the pressable member to return.
