Title: Synchronization circuit for spread spectrum communication system
Inventor: NAGASAWA SATOSHI
IPC: H04B1/707
Filed: 1996-08-13
Abstract: PROBLEM TO BE SOLVED: To maintain stable synchronization. SOLUTION: A correlation output outputted from an inverse spread circuit 1 is logarithmically compressed by a logarithmic compression circuit 2. A phase of a PN code generated from a PN code generator 9 based on a correlation output Sa subject to logarithmic compression is controlled to maintain the synchronization stably even when a level of an input signal is considerably fluctuated. Furthermore, the logarithmically compressed correlation output Sa is fed to a demodulator 4 so as to omit the use of an AGC amplifier in the demodulator 4.

Abstract: PURPOSE:To control the vertical resolution characteristics of an image outputted from a solid-state image pickup element without using a delay line on the outside of the element by providing the image pickup element with a function for simultaneously reading out two lines and computing a pair of two signals simultaneously outputted and adjacent to each other in the vertical direction. CONSTITUTION:The charge of a picture element An in the solid-state image pickup element 1 to be a CCD image sensor having the function for simultaneously reading out two vertically adjacent picture elements and that of a picture element Bn are simultaneously read out respectively through amplifiers 2, 3. A signal from the picture element Bn read out simultaneously is multiplied by a prescribed coefficient through a coefficient multiplier 7 and the multiplied result is added to a signal from the picture element An by an adder 8. When the coefficient K7 of the coefficient multiplier 7 is defined as '1', the vertical spatial-frequency characteristic is dropped and turned to zero by Nyquist frequency fv. In the case of K7=0, the vertical spatial frequency characteristic is determined by the vertical numerical aperture or the like of one picture element. Thereby the vertical spatial frequency characteristic can be controlled by setting up the K7 to a proper value.

Title: Blood oxygen sensor for pacemaker and measurement method thereof
Inventor: SETSUDO MOOTAZABI
IPC: A61N1/05
Filed: 1990-08-31
Abstract: PURPOSE: To obtain a blood oxygen sensor which reduces the complexity of a drive circuit and electric power consumption by utilizing the fact that the time length between the first time point that an electric current generator illuminates a light emitting diode and an integrated voltage output has reached the pre-determined threshold, is in reverse proportion to the oxygen level in blood. CONSTITUTION: At a time point T1 that an electric current generator illuminates a light emitting diode 32, the light emitting diode begins to release light energy E1 . At this time point, the voltage applied to the terminals 28 & 30 is V1 . The light energy E2 is reflected to a light detector 34 which supplies the electric output to an integrator 36 that begins to integrate the electric current output of the light detector 34. At the time point T2 when the integrated current output of the light detector 34 reaches the threshold of a threshold detector/latch 38, a latch circuit of the threshold detector/latch latches it. Then, the voltage applied to the terminals 28 & 30 goes down from V1 to V2 . By monitoring this voltage, one can measure the time points T1 & T2 . The time difference between T2 and T1 indicates the total oxygen content of blood.
