Abstract: An object gripping device using a electromagnetic assembly includes a base having two opposite ends thereof, a fastening portion pivoted at one end of the base and having an object-gripping trench and a through opening having a stopping surface therein at two opposite ends of the fastening portion, a transmission portion pivoted at the other end of the base, a stopping shaft extending through both the transmission portion and the through opening, a first spring connected both the base and the fastening portion, a second spring connected both the base and the transmission portion, and a electromagnetic assembly connected the base and the transmission portion.

Abstract: A portable electronic device comprises an upper member, a lower member having two guiding grooves, two supports and two connecting members. One end of each support is pivoted to the upper member with a first pivot portion. The other end of each support is pivoted to the lower member with a second pivot portion. One end of each connecting member is pivoted at one side of the upper member, and the other end thereof is restricted in the guiding groove and capable of reciprocally sliding in the guiding groove.

Abstract: An object gripping device using a solenoid valve includes a base having two opposite ends thereof, a fastening portion pivoted at one end of the base and having an object-gripping trench and a through opening having a stopping surface therein at two opposite ends of the fastening portion, a transmission portion pivoted at the other end of the base, a stopping shaft extending through both the transmission portion and the through opening, a first spring connected both the base and the fastening portion, a second spring connected both the base and the transmission portion, and a solenoid valve connected the base and the transmission portion.

Abstract: A protection cover mechanism is disclosed. A hollow hinge tube is connected to a protective cover. A first hinge cover body is connected to the hollow hinge tube and includes a positioning rib. A spring is disposed in the first hinge cover body and abuts the hollow hinge tube. A hollow driven member is movably disposed in the first hinge cover body and abuts the spring. The spring is abutted between the hollow hinge tube and the hollow driven member. The hollow driven member includes a protrusion. The positioning rib is positioned on the hollow driven member, forcing the hollow driven member to move linearly with respect to the first hinge cover body. A fixing base includes a hollow tube fit on the hollow driven member and having an annular inner guide track with an undulated profile. The protrusion abuts the annular inner guide track.

Abstract: An apparatus for permitting hands-free operation of a mobile telephone unit in a car includes a wireless microphone transmitter for generating wireless outgoing signals corresponding to sounds picked up in the passenger room of a car, and a main terminal which has a terminal housing with one end adapted to be inserted into a cigarette lighter socket of the car. A receiver circuit is disposed in the terminal housing and is capable of receiving the wireless outgoing signals from the transmitter. A telephone connector is adapted to be connected electrically to the mobile telephone unit and enables the mobile telephone unit to receive the wireless outgoing signals from the receiver circuit and transmit wirelessly the wireless outgoing signals. Wireless incoming signals received by the mobile telephone unit are received by a loudspeaker in the terminal housing. The loudspeaker generates an acoustic output corresponding to the wireless incoming signals.
