  • Patent number: 8411848
    Abstract: In a telephone interface circuit, a first NPN transistor switch-controls a connection between a speech circuit and a pair of subscriber lines. A second PNP transistor controls an on/off state of the first transistor. A positive feedback circuit connects a collector terminal of the first transistor to a base terminal of the second transistor. An internal power source supplies current for driving the second transistor. The first transistor operates in a saturated region when a voltage that is in a range of standard voltages delivered over a pair of subscriber lines for normal operating conditions of a subscriber line device that is not being subjected to an over-voltage or an over-current event is applied in between the pair of the subscriber lines. The first transistor operates in an unsaturated region when an overvoltage exceeding said range of standard voltages is applied in between the pair of the subscriber lines.

  • Patent number: 8020214
    Abstract: According to one embodiment, a transmitter is configured to transmit content to a receiver. Available dubbing count is set in advance for the content such that the content can be dubbed a plurality of times. The transmitter includes a key exchanger, an encryption processor, and a dubbing management module. The key exchanger performs key exchange to share a common key with the receiver. The encryption processor encrypts, in response to a content request received from the receiver, the content with the common key to transmit the content to the receiver. The dubbing management module reduces, upon receipt of a right transfer request related to the use of the content from the receiver, the available dubbing count by dubbing count indicating the number of times of dubbing of the content. The dubbing count is contained in the right transfer request.

  • Patent number: 7995744
    Abstract: A hook switch turns on a transistor by connecting the positive electrode terminal of a capacitor to a base terminal of a transistor in an off-hook state, causing a speech circuit and telephone lines to be connected. The hook switch turns off the transistor by disconnecting the positive electrode terminal of the capacitor from the base terminal of the transistor in an on-hook state, causing the speech circuit and the telephone lines to be disconnected. A holding circuit holds the voltage at the positive electrode terminal of the capacitor at a substantially fixed value by charging the capacitor with electric power supplied from the telephone lines in an off-hook state.
