Abstract: A periodic and automatic telephone redialling system and method applicable to a dial-type communication device is proposed to provide a periodic and automatic telephone redialling procedure on phone numbers previously dialled by a user but failed to get through to the receiver. The advantages of this periodic and automatic telephone redialling system and method are that the user does not have to activate the redialling procedure manually, and the redialling procedure can be performed periodically for one or more phone numbers.

Abstract: An electronic device includes a main body having a connection portion for electrically connecting the electronic device to an external device; a sheath for the main body to be slidably received therein; at least one positioning component provided in the sheath, for fixing the main body when the main body is sliding toward a first terminal of the sheath and arrives at a fixing position such that the connection portion is protruded from a first opening formed at the first terminal in order to use the electronic device; and at least one first elastic component provided in the sheath, for pressing the main body to move toward a second terminal of the sheath when the main body is released from the fixing position and is sliding toward the first terminal of the sheath, such that the connection portion is received in the sheath in order to store the electronic device.

Abstract: A flashlight lamp circuit with automatic light adjustment includes a flashlight charging unit for controlling charging of a main capacitor, a flashlight activation unit activating the flashlight lamp to project a flashlight on the photographed object according to a flashlight control signal, a light sensor receiving and converting a light from the photographed object into an electric signal, an integral circuit receiving the electric signal and having an adjustable circuit resistance. When the amount of flashlight reaches a required light exposure, the flashlight control unit extinguishes the flashlight lamp.

Abstract: A slim USB electronic device, which includes a substrate and a housing enclosing the substrate, is disclosed. The substrate includes a circuit board and an extended connector. Electrically conductive metal strips are adhered to the connector, and integrated circuit elements are mounted on the substrate. The housing has openings, through which the corresponding metal strips are exposed and electrically communicate with the contacts of an USB receptacle.

Abstract: An improved pushbutton has a pair of elastic sections sandwiching a protrusive button. The elastic section includes a pair of elastic and flexible strips formed in an undulate manner to become a buffer member abutting a lateral side of the button to position the button in a vertical fashion. When the button is subject to a force the elastic sections may be compressed. When the force is released, the elastic sections are extended. The button may be embedded in a LCD panel at a smaller space, thus the overall size of the panel may be reduced.

Abstract: A system and method for tracking a mobile unit with a GPS system is provided. The system obtains the position data of the mobile unit by communication between the mobile unit and at least three GPS satellites. Then, the position data is transmitted to the master control station through a local area satellite and stored in the master control station. The PVR user only needs to transmit the ID of the mobile unit to the master control station through a communication network. Then, the master control station transmits the position data of the mobile unit to the PVR and shows an E-map on the television screen, to show the user where the mobile unit is.

Abstract: A fastening mechanism for a portable digital audio player is proposed and adapted for connecting the body of a portable digital audio player to an external device or surface, the fastening mechanism including: a first positioning member installed on one side of the body of the portable audio player, a blocking member installed on one side of the first positioning member, a second positioning member installed on one side of the first positioning member apart from the blocking member, and a fixing base adapted for connecting with an external device having a third positioning member that corresponds to the first positioning member, and a fourth positioning member that corresponds to the second positioning member, thereby allowing the portable audio data player to be fastened to an external device/surface securely.

Abstract: An intelligent VOIP telephone system and communication method thereof used in a restaurant utilizes a VOIP telephone network to assist the management of the restaurant. The system comprises a main server and at least one VOIP telephone. The main server comprises a document database and a check module. The communication method comprises the following steps: correcting an arranged document in a main server, and transmitting updated data to the VOIP telephone. Then, the VOIP telephone updates the data according to the arranged document. The VOIP telephone gets a request from customers, combines the request and related data to form a packet, and transmits the packet to the main server. Finally, the main server processes the request and sends a confirmation message to the VOIP telephone.

Abstract: A connector structure is proposed, which includes a body having at least one containing space; at least one first connector being inwardly disposed at one end of the body; at least one second connector being pivotally disposed on the other end of the body, which can be accommodated in the containing space of the body; and at least one rotating element being pivotally connected onto one end of the body, the second connector being fastened onto the rotating element, wherein the rotating element at least has one arm portion, one end of the arm portion being disposed with a pivotal connecting portion which connects to one end of the body. The connector structure further has a switch actuated by the rotation of the pivotal connecting portion of the rotating element thereof, wherein the rotation angle of the switch can control electric conduction of the first connector and the second connector.

Abstract: A backlight controlled closeup photographing system is proposed, which is designed for use with a multimedia-capable information platform, such as an MMV (MultiMedia Viewer) device, to allow the user to photograph a small object, such as a business card, at close range with intensified illumination on the object for the purpose of allowing the photographed digital image to have adequate brightness in picture quality. The proposed backlight controlled closeup photographing system is characterized by the use of backlight control to increase the intensity of the backlight illumination on the object being photographed for the purpose of allowing the photographed digital image to have adequate brightness in picture quality. Since the intensity of illumination on the object can be increased without using flash unit, the invention is apparently more cost-effective and advantageous to use than prior art.
