Title: Method of charging a secondary battery and apparatus for the same
Inventor: MATSUURA KOUJI
IPC: H02J7/04
Filed: 1998-02-06
Granted: 1999-07-11
Abstract: The present invention provides a charging apparatus for secondary battery comprising a DC/DC transformer for output a predetermined DC voltage and a predetermined DC current confined by a voltage setting circuit and a current limiting circuit respectively; a control circuit inductively connected to the voltage of secondary battery of said apparatus, and a first current that sets the current limiting circuit in a predetermined current range until the battery voltage attains full-charge voltage. Meanwhile, said control circuit switches on/off a charging switch circuit to apply the first current to the battery in the form of pulse. As soon as the battery voltage attains full-charge state, said controlled voltage in the form of dual level pulse is used to alternatively apply a current lower than the predetermined current range and a current in the predetermined range to said battery. Said apparatus can reduce charging time, and will not increase the load on switch device and therefore can assure the safety for battery.

Title: A real-time single pass variable bit rate control strategy and encoder
Inventor: MOUSENIAN NADER
IPC: G06T9/00
Filed: 1998-06-25
Granted: 2000-09-01
Abstract: A real-time single pass variable bit rate control strategy is provided to achieve variable bit rate (VBR) MPEG-2 encoding in a video compression system. For a sequence of frames, the level of encoding difficulty of a video interval (i.e., a group of pictures (GOP)) is determined by a perceptual rate-quantization (C-Q) model. This model assigns a composite (C-Q) curve to each video interval from which the number of bits for the video interval is estimated. The estimation relies on a causal predictive model using the parameters obtained from previously encoded video intervals. The R-Q relationship of each picture type is updated and picture bits are assigned, based on the total rate of the video interval under analysis. Robustness of the variable bit rate control  strategy is ensured throughout scene transitions and instabilities by applying, for example, a non-linear median filter, and a low pass filter, respectively.

Title: Optical transmission system and optical transmitter and optical receiver used therefor
Inventor: FUSE MASARU
IPC: H04B10/54
Filed: 1998-08-21
Granted: 2000-03-11
Abstract: An angle modulating portion 1 converts an inputted electrical signal into a predetermined angle-modulated signal. An optical modulating portion 2 converts the angle-modulated signal outputted from the angle modulating portion 1 into an optical-modulated signal and sends the optical-modulated signal to an optical waveguide portion 3. An interference porton 6 separates the optical-modulated signal transmitted through the optical waveguide portion 3 into two optical signals having predetermined difference in propagation delay and then combines the optical signals. An optical/electrical converting portion 4 subjects the combined optical signal to homodyne detection, to acquire a demodulated signal of the original electrical signal and output the electrical signal. That is, the interference portion 6 and the optical/electrical converting portion 4 constitute a delayed detection system of an optical signal, so that the delayed detection system performs conversion processing of an optical signal into an electrical signal and angle demodulation processing simultaneously. In this way, a signal with a wide-band and a high-frequency can be acquired by demodulation without electrical part for wide-bands and high-frequencies.
