The present invention concerns a monitoring camera for picking up the image of an environment inside or outside a building. A ceiling part (13) is provided in one end side in the longitudinal direction of a rectangular main body part (11). On the other end side, a bottom surface part (14) is provided. Since an image pickup part (12) is provided in the front part of the main body part (11) held between the ceiling part (13) and the bottom surface part (14), the monitoring camera can be disposed a...

In order to suppress leak current at the time of high voltage application to a fluorescent lamp so as to improve the luminous efficiency, the present invention provides a fluorescent lamp driver, which includes switching means that switches a DC power supply voltage, and a first transformer and a second transformer configured to obtain AC voltages each having reverse polarity, as AC voltages excited from primary winding to secondary winding of the respective transformers, on the basis of output ...

Preventing a molded disc substrate from generating a separation pattern. To this end, a molding die 1 includes a pair of stationary die 6 and movable die 7, and an outer circumference ring 16 for molding an outer circumference end of the disc substrate 2. The outer circumference ring 16 is so mounted as to be movable along forward and backward directions in parallel with a moving direction of the movable die 7 toward the stationary die 6, and has a retaining surface 39 for retaining the outer ci...

A communication apparatus used for two-way speech wherein the acoustic couplings between a speaker and microphones can be made equal by a simple method, wherein radially arranged microphones are located at equal distances from a speaker, a test signal generation unit outputs a pink noise signal to the speaker, the signal is input to a microphone detecting the sound of the speaker through variable gain amplifiers, attenuated in variable attenuation units, the peak value of absolute values of diff...

A data processing apparatus constituting a low-cost audio/video data transmission and reception system is disclosed. A reception buffer monitoring circuit 21 monitors the size of receiver data being accumulated in a reception buffer 6. When the size of accumulated data is found to become higher than a high threshold, the circuit 21 causes a reception clock generation circuit 8 to generate a reception clock with a higher frequency. When the accumulated data size becomes lower than a low threshold...

The present invention relates to an apparatus and a method for content reproduction, a recording medium, and a program that make it possible to edit taken images easily and automatically in accordance with an intention of an editor. Each time a reproduction is performed, a reproduction start point and a reproduction end point of VOBU units of images reproduced by a disk camcorder are recorded in Play Data 81. The recorded reproduction start point and reproduction end point are read, and edit poi...

A data transmission device transmits a data broadcast using a narrow unused broadcasting band in a digital broadcast, and to record the data broadcast, which has been received, on a receiving side so that the receiving side can play back the data broadcast after a data stream is totally recorded. The transmission device generates a first data stream, which is recorded on a recording medium on a receiving side, and a second data stream including audio and video data, which is transmitted as a bro...

To reduce calculation errors of remaining batter power so as to take into account capacity diminutions due to cycle degradation and temperature, a remaining power calculation device specifies a temperature correction value for calculation of remaining battery power corresponding to temperature, from among temperature correction values changed every predetermined number of charge/discharge cycles stored in a correction value storage device, on the basis of a temperature of a battery cell measured...

Disclosed herein is a data transmission system permitting secure and more reliable transmission of data from a data transmitter to a data receiver or receivers. The system comprises: a data transmitter for encrypting data and transmitting the encrypted data; data receivers for receiving the encrypted data from the data transmitter; satellite links used for data transmission from the data transmitter to the data receivers; and bidirectional communication channels which are also used for transmitt...

Autofocus device has a lens-driving unit that drives a lens and a focal-point-position-detecting unit that detects a position of a focal point of the lens. The device also has a distance-measuring sensor that measures a distance to a subject and a control unit that performs a focusing operation to control the lens-driving unit to drive the lens, thereby meeting the position of the focal point of the lens detected by the focal-point-position-detecting unit to an in-focus position thereof. The con...
