Abstract: A semiconductor structure includes a substrate, and an active device and a passive device over the substrate. The active device is disposed in a first region of the substrate, and the passive device is disposed in a second region of the substrate. The semiconductor structure further includes a shielding structure and a passivation layer. The shielding structure includes a barrier layer and a ceiling layer. The barrier layer is on the passive device and the active device, and the ceiling layer is on the barrier layer. The passivation layer is under the barrier layer and covers a top surface of the passive device. An air cavity is defined by sidewalls of the barrier layer, a bottom surface of the ceiling layer, and the substrate.

Abstract: The wireless electric charging module for a storage battery takes advantage of a voltage sensing circuit and a current sensing circuit to get an error control signal, through a controlled calculation method (PID), the storage battery can be efficiently controlled to get a direct electric power source for wireless sending in electricity charging, to thereby overcome the phenomenon that the voltage of the storage battery is overly low and unstable in conventional techniques and needs a voltage rise circuit to get a stabilized electric power source, and to overcome the problems in relating to the cost of circuits and the efficiency of conversion of energy.

The portable electric toothbrush includes: a main body having a switch; a brush head having a plurality of bristles and connected to one end of the main body; a holding portion connected to the other end of the main body; a charging circuit configured in the main body; a chargeable battery coupled to the charging circuit; a control circuit coupled to the switch; a motor coupled to the control circuit; and an USB interface coupled to the charging circuit, whereby providing electricity to the chargeable battery, thereby achieving the purpose of charging.

Abstract: An induction type power supply device includes a power supply base unit having a connection interface connectable, an oscillator circuit for producing an AC signal upon connection of the connection interface to an electric outlet, a driver circuit for amplifying the AC signal and a primary inductor for obtaining a resonant frequency and releasing the AC signal, and an attached induction device placed on the power supply base unit and having a secondary inductor for receiving the AC signal from the primary inductor by means of magnetic induction, a rectifier filter circuit for converting the AC signal into a DC power supply, a power management circuit for regulating the DC power supply subject to a predetermined voltage and current value and a connection device for the connection of an external mobile electronic apparatus and for outputting the regulated DC power supply from the power management circuit to the connected external mobile electronic apparatus.

Abstract: A battery cover suitable for being used to cover a battery groove of an electric appliance such as a game controller, a remote controller, a mobile phone, a multi-medium player, a wireless mouse, a flashlight, a PDA, a digital camera etc. to generate electric power in a wireless inducing mode, for charging chargeable batteries that can thus supply electric power for operation of an electric appliance. Therefore, when a user is desired to electrically charge the chargeable batteries, it needs not to take the chargeable batteries out of the electric appliance, but needs only to directly place the electric appliance in an effective wireless induction zone to make the battery cover generate electric power in a wireless inducing mode to charge the batteries.

Abstract: An insulation type electric charging structure/chargeable battery, wherein a receiving circuitry is provided in a chargeable battery having a power storage member, the receiving circuitry further has a receiving coil; when the receiving coil receives an alternative signal from outside in a non-contacting insulated mode, it changes the signal into electric power to do electric charging for the power storage member, thereby the battery does charging without conducting by contacting electrodes. Thus the electric charging needs no clamping connecting to or abutting on the electrodes of the battery; and chargeable batteries of which the sizes and lengths are different can be charged with the same seat; and in the non-contacting insulated charging mode, the battery can be charged without detaching and removing when it is fixed in an electric appliance.
