Title: Adaptive antenna array processor using composite reference signal being coherent andconstant modulus
Inventor: GOLDEN GLENN DAVID
IPC: H04B7/08
Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To improve the performance by generating and combining weighted receive signals by weighting respective receive signals by using the weighted mean value of a coherent reference signal value and a constant modulus reference signal value as a composite reference signal. SOLUTION: Both component reference signals generated by multiplying the coherent reference signal 2221 by a weighting parameter βand the constant modulus reference signal 2222 by (1-β) are combined additively by an adder 2217 to generate the composite reference signal Zn 2219. This composite signal drives a weighted calculation process. A continuously adjustable weighting parameter β 2225 determines the point where characteristics similar to CMA of the composite reference signal 2219 and characteristics similar to coherence meet each other. To quicken convergence during initial weighted acquisition and exclude constant modulus interference, a numeral which is close to 1 or 1 can be selected as β. Then β can be shifted toward zero so as to reduce the influence of phase rotation and a determination error.

Title: Charging of sealed lead storage battery
Inventor: YAGIYUU YOSHIHISA
IPC: H01M10/44
Filed: 1981-07-17
Abstract: PURPOSE:To supply the insufficient charge caused due to short time chargings, and obtain a  battery which has a stable and excellent charge-and-discharge cycle life by minimizing gas  generation, and charging the battery with a current pattern set by a timer. CONSTITUTION:At the first stage, a lead battery is charged with a constant or semi-constant  current until a given battery voltage is achieved, and the final battery voltage is determined  so that the pressure of the internal produced gas becomes below the sealing pressure of a  safety valve. At the second stage, a current is subjected to a scanning by using a CR circuit  as a timer, and the value of the current is adjusted between the final charging current value  of the first stage and the current value of the third stage. At this stage, voltage is uncontrolled although it depends on the capacity of the transformer of a charger, the pattern of a  charging current doesn't change during the charge-and-discharge cycle, and an early capacity  deterioration caused by the repetition of insufficient chargings is supplied by a compulsory  charging. Following that, at the third stage, the current is switched to a micro-current, the  current value is determined according to the overvoltage-resisting ability of the battery, and  the voltage is uncontrolled. Thus charging of the battery is performed according to the above  three stages. Consequently, the unstable charge-receiving performance of the battery is rectified in the second stage by charging the battery with the current pattern set by the timer, and gas generation is minimized.
