The imaging module is connected to the illumination module and includes a housing, a relay optical system, and a projection optical system. The housing has a first annular receiving groove and a second annular receiving groove. The first annular receiving groove is closer to the illumination module than the second annular receiving groove. A center axis line of the first annular receiving groove and a center axis line of the second annular receiving groove are on the same axis line. The relay optical system includes a lens received in the first annular receiving groove. The projection optical system includes a lens and a reflecting mirror received in the second annular receiving groove. Mirror centers of the lenses and a mirror center the reflecting mirror are located on the same axis line.

Abstract: A driving safety warning device includes a central processing unit (CPU); an acceleration sensor for sensing an acceleration value of a car having the driving safety warning device installed therein, and sending the sensed acceleration value to the CPU for calculating, so as to obtain a driving speed value; and a gyro sensor for sensing a deviation angular speed value of the car in moving, and sending the sensed deviation angular speed value to the CPU for calculating. When the obtained driving speed value exceeds a preset value, a driving safety warning function is actuated; and when the obtained deviation angular speed value exceeds a preset maximum safety deviation angular speed value or exceeds a preset safety deviation angular speed value for wandering car while a timer is enabled and a reverse sway occurs when the timer is counting, a warning sound is emitted to remind the driver.

Abstract: A sliding mechanism for a cellular phone includes a low-profile base provided on one surface with a central recess and a pair of parallel elongated sliding slots located at two lateral sides of the recess; a supporting bracket slidably connected to the surface of the base with the recess; and a plurality of flat elastic members each having a first and a second telescopic element respectively pivotally connected to the base and the supporting bracket. The base is enclosed in a plastic material through insert molding to have a slim body that enables a reduced overall thickness of the cellular phone. And, the flat elastic members allow the supporting bracket to smoothly slide relative to the base in a balanced manner.

Abstract: A method for automatically changing incoming call alert profile upon the current location, implements on a GPS-functioned portable communication device. The method continually obtains a location coordinate, compares the location coordinate with a comparison list to match an incoming call alert profile for the portable communication device's current incoming call alert profile. Thus, wherever the portable communication device moves to, a reaction will be presented automatically according to the current incoming call alert profile when an incoming call comes.

Abstract: A system for wireless communication network is disclosed. The system includes several nodes and at least a gateway. Each of the nodes includes several first wireless network interface. Each of the first interfaces utilizes one of channels to send, receive or forward signals. Wherein the first interfaces of the same node utilize different and non-overlapping channels to send, receive or forward the signals at the same time. Each of the gateways includes a network interface and several second wireless network interfaces. The network interface connects to the Internet to receive or forward the signals. Each of the second wireless network interfaces utilizes one of the channels to receive or forward the signals. Wherein the second wireless network interfaces of the same gateway utilize different and non-overlapping channels to receive or forward the signals at the same time.

Abstract: A handheld communication apparatus includes a metallic insert molding member, a circuit board and a shielding frame. The metallic insert molding member includes a metal plate. An electronic component is mounted on the circuit board. The shielding frame defines opposite first and second openings, wherein the shielding frame is bonded to the metal plate of the metallic insert molding member at the first opening, thereby forming a shielding case. The electronic component on the circuit board is inserted into the second opening of the shielding frame to be shielded by the shielding case.

Abstract: A structure of a shielding case is changed into a fixing apparatus for holding a digital photography module on a mobile telephone. A first component of the fixing apparatus has several folded sides. These folded sides are used to fix the horizontal movement of the digital photography module. A second component of the fixing apparatus has at least one engagement portion. The engagement portion is used to fix the vertical movement of the digital photography module.

Abstract: A mobile phone positioning apparatus provides a rotational movement and switching functionality among three planes (H, E1 and E2) as requested by a radiation test. The positioning apparatus includes a base, a support shaft, a platform and a testing plane switch apparatus. The testing plane switch apparatus is mounted on the platform. An inverse U frame is fixed on the platform. A testing frame, pivotally connected to the inverse U frame, is rotated by two pneumatic cylinders so as to switch between the H plane and either the E1 or E2 plane by 90 degrees. A testing plate, pivotally connected to the testing frame, is rotated by another pneumatic cylinder so as to switch between the E1 and E2 planes by 90 degrees.

Abstract: A mobile communication device with a battery strap is provided. The mobile communication device with a battery strap includes a main device; and a battery strap electrically connected to the main device for providing a battery power to the main device and worn by a user.

Abstract: An automatically notifying system for testing a cellular phone module is provided. The system includes a control computer having a testing program for providing a test request, a testing device electrically connected with the control computer and the cellular phone module for testing the cellular phone module in response to the test request, and sending a test status back to the control computer, such that the testing program generates a trigger signal in response to the test status, and a control module electrically connected with the control computer for sending a warning message to a communication group in response to the trigger signal.

Abstract: The present invention is an automatic testing system for a cellular phone module and a method thereof for automatically test a cellular phone module. The present invention includes a control computer having a graphic controlled program for providing a test request, wherein the graphic controlled program is written in Labview program, and a testing device electrically connected to the control computer and the cellular phone module for testing the cellular phone module in response to the testing request.
