摘要:
A method and system for reducing systematic errors in an optical system that makes aerial surveillance position measurements. The flight vehicle executes a trajectory within line-of-sight of a reference target object whose actual position is known to a suitable degree of accuracy, and a set of position measurements is made. From these measurements a set of radial error values is derived, based on the known position of the target reference. From this set, coefficients are computed for insertion into functions of one or more input variables, used as compensating factors to reduce the error in the position calculations. These coefficients and compensating factors are then used in making aerial surveillance position measurements for other target objects.

A distortion compensating circuit is provided in which, in the polar modulation system, while suppressing increase of compensation data and increase of the circuit scale, a modulated signal can be correctly expressed, or low-distortion characteristics of a power amplifier can be realized. Based on a steady characteristic compensating circuit 11 which stores an output signal amplitude and output phase characteristics with respect to a control voltage in a steady state, amplitude adjustment is executed on amplitude information r11(t) on which amplitude correction is performed, by a first amplitude information adjusting portion 13, whereby the output-response characteristics of an output signal amplitude of an amplifier with respect to a change of the control voltage can be improved.

The present invention relates to planar electrochemical sensors with membrane coatings used to perform chemical analyses. The object of this invention is to provide unit-use disposable sensors of very simple and inexpensive construction, preferably with only a single membrane coating on an electrode. The invented devices are potentiometric salt-bridge reference electrodes and dissolved gas sensors constructed with a heterogeneous membrane coating of a conductor. The heterogeneous membrane, which is an intimate admixture of a hydrophobic and a hydrophilic compartment, concurrently supports constrained transport of non-volatile species through its hydrophilic compartment and rapid gas and water vapor transport through its hydrophobic compartment.

A surface acoustic wave device having a three-layered structure of sealing resin for sealing a mounting substrate and a surface acoustic wave element in which the elastic modulus of resin of the intermediate layer is higher than that of resin of the outermost layer and the elastic modulus of resin of the innermost layer is lower than that of resin of the outermost layer. The three-layered structure of the sealing resin suppresses crush of a bump when a pressure is applied from the outside and reduces stress applied to the bump due to the change in temperature.

In order to realize a demodulator circuit and a demodulation method of controlling the amplification degree of an AGC in order that the optimum C/N value near the best C/N value can be always secured in the whole AGC voltage region, the amplification degrees of AGC's 122 and 126 is controlled based on a change of the reception grade of a received signal having been outputted from a FFT 132 of a demodulator circuit unit 13 after being received by an antenna 11 and being amplified by a tuner unit 12. Consequently, the amplification degree can be immediately modified according to a change of the reception grade, and consequently the optimum reception grade can be secured always.

The peak of a histogram in a first flash preemission and the peak of a histogram in a second flash preemission performed with a light emission amount different from that of the first flash preemission are obtained, and the change ratio of the histogram peak value with respect to a change in flash light emission amount is calculated. By taking this change ratio into consideration, a flash light emission amount for image sensing is calculated. Image sensing is performed by causing the flash to emit light with this image sensing light emission amount.
