Title: Sonic velocity variation covariance matrix forming method and ocean acoustic tomography analysis device
Inventor: ITO TAKAO
IPC: G06F7/544
Filed: 1995-07-18
Abstract: PROBLEM TO BE SOLVED: To estimate a variation quantity of sonic velocity which reflects the structure of the ocean by a method wherein an opposite angle element of a sonic velocity variation covariance matrix by each of intervals is formed and a non-opposite angle element in the identical interval is set to zero. SOLUTION: A square sum of development coefficients of data of a variation quantity of already existing sonic velocity in each interval is calculated and the calculation result is divided by the number of pieces of data in each interval to obtain the average value. An opposite angle element in each interval of a sonic velocity variation covariance matrix which is used for the probability theoretic estimation is formed from the average value and a non-opposite angle element in the identical interval is set to zero to form the sonic velocity variation covariance matrix. That is, the square sum γij (i, j a number of interval and a number of a development function, respectively) of development coefficient data of each development function in each interval is obtained and it is divided by the number Qi of pieces of data in each interval to obtain a value Eij .  All of the values Eij of the whole intervals are added and the result is divided by a specific value λj of corresponding development function and a total number (q) of the intervals to obtain a value Aj . The value Eij is divided by the value Aj and the obtained value Γij is inputted to the opposite angle element of the covariance matrix.

Abstract: PURPOSE:To shorten the time for the actual room temperature to converge to the desired value even under the large load fluctuation during cooling or heating operation and consequently contrive to improve the responsiveness by a method wherein the width of step, by which the rotational frequency of a compressor is increased and decreased, is changed in response to the temperature deviation or the larger the temperature deviation between the actual room temperature and the desired value of room temperature is, the larger the width of step is made. CONSTITUTION:A first frequency setting signal generating means 21 generates the signal, which makes the change of the rotational frequency of a rotational frequency variable type compressor 3 larger in proportion to the magnitude of the temperature deviation. A second signal generating means 22 checks the generation of signal when the signal to change the rotational frequency in large scale is the zero signal, resulting in rotating the compressor 3 at its lowest rotational frequency. When the temperature deviation lies in a temperature region not exceeding the set value, a third signal generating means 24 checks the generation of the minimum signal and at the same time generates the zero signal. The compressor 3 is driven based upon the respective setting signals as mentioned above.

Title: State observer for detection of speed signal
Inventor: IWASAKI TAKASHI
IPC: G01P3/42
Filed: 1987-07-23
Abstract: PURPOSE:To reduce a memory capacity for estimating speed, by computing the current estimated speed value based on an input from an actuator, a shift of position in the preceding computation as obtained from a position detector and an estimated speed value in the preceding computation. CONSTITUTION:An actuator 1 outputs a movement value y(k+1)-y(k) following the preceding operation from a position detector provided thereon 1 shifting the position thereof receiving an input signal mu(k) sequentially. For example, when the position detector employs an incremental encoder, the incremental encoder normally outputs a moving value after the preceding operation as position information, hence allowing the use of the position information as intact. Then, a state observer 2 computes the current estimated speed value from the movement value y(k+1)-y(k), the input mu(k) of the actuator 1 and the preceding estimated value. This permits the use of only the movement value following the preceding operation as information from the position detector necessary for the estimation of the current speed thereby enabling a reduction in the memory capacity as position information.
