Abstract: The invention discloses a battery configured in a mobile communication apparatus. The battery comprises a contacting portion and a connecting portion. The contacting portion comprises a plurality of first conductive terminals for electrically contacting to an information component. The connecting portion comprises a plurality of second conductive terminals for electrically contacting to the mobile communication apparatus, wherein at least one part of the second conductive terminals connects to the first conductive terminals to enable the information component to transmit a signal to the mobile communication apparatus through the first conductive terminals and the at least one part of the second conductive terminals. Accordingly, the mobile communication apparatus and the information component are protected from damage, and the thickness of the mobile communication apparatus will not be limited by the information component connector.

Abstract: The invention discloses a hinge connector installed in a foldable electronic apparatus. In particularly, the hinge connector according to the invention includes a hollow shaft device and a cable connecting connectors, and the cable passes through the shaft device.

Abstract: The invention is to provide a monitoring apparatus capable of communicating with a mobile communication apparatus. The monitoring apparatus according to a preferred embodiment of the invention includes a base, a rotating device, a casing, an image capturing module, a transmitting/receiving unit, and a processing/controlling module. The image capturing module is used for capturing an image and transmitting the captured image. The processing/controlling module is used for receiving a control signal transmitted from the mobile communication apparatus through the transmitting/receiving unit, controlling, according to the control signal, the rotating device to actuate the image capturing module together with the casing and the rotation shaft to rotate to a desired angle, receiving the captured image, and transmitting the captured image to the mobile communication apparatus through the transmitting/receiving unit.
