Abstract: Disclosed is an apparatus and method for prevention of interferences from speech sounds in telephony. The apparatus comprises a cipher generation unit, an automatic speech sound sending digital processor and an incoming call filter unit. When a receiver receives an incoming call from a sender, a cipher is generated. Next, the receiver sends a speech sounded cipher to the sender based on the generated cipher. Responsive to the speech sounded cipher, the sender inputs a response cipher with reference to the speech sounded cipher. Finally, the inputted cipher and the cipher generated at the receiver end are compared, so that the receiver may determine if the incoming call is a voice-over-internet protocol (VOIP) SPAM and should be answered.

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.

Abstract: A connector concealment mechanism for computer peripheral device is proposed, which is designed for use in conjunction with a computer peripheral device equipped with an external connector for the connector to be concealable into the casing of the computer peripheral device when not in use, and be easily ejected out of the computer casing for use to connect the computer peripheral device to a computer unit. This feature allows the computer peripheral device to be more advantageous to use than the prior art due to the fact that it allows the user to conceal the connector into the casing of the computer peripheral device when not in use, without having using a separable cap which would easily get lost as in the case of the prior art, thus making the use of the computer peripheral device more convenient and trouble-free than prior art.
