  • Publication number: 20160163178
    Abstract: A water level alarm device includes first and second magnets, a wire, an insulated connection line, a floating body, an amplifier, and an alarm. The wire passes through a gap between the first magnet and the second magnet. The floating body floats in water of water storage equipment. When a water level of the water storage equipment is lower than a reference value, a buoyancy force of the floating body is less than a gravity of the floating body, the floating body pulls the insulated connection line, the insulated connection line vibrates, and the wire vibrates accordingly. The wire cuts magnetic induction lines between a north pole of the first magnet and a south pole of the second magnet to generate induced current. The induced current is amplified by the amplifier and then is output to the alarm, to control the alarm to alarm.

  • Patent number: 7033187
    Abstract: An electrical connection and a method of electrically coupling are disclosed. In one embodiment, a circuit substrate with a first set of circuitry has a bonding pad mounted to a surface of the circuit board. The bonding pad is electrically coupled to the first set of circuitry. A flexible circuit substrate with a second set of circuitry has a connecting pad mounted to a surface of the flexible circuit substrate facing the surface of the circuit board. The connecting pad is electrically coupled to the second set of circuitry. A ball of conductive material is mounted on the bonding pad. A clamping device presses the connecting pad to the ball of conductive material.
