Abstract: A sensor package 10 includes a plurality of sensors 19 and a container 18. Each of the sensors 19 detects a detection target component in the fluid. The container 18 includes an inner channel 21 and a first surface os1. The plurality of sensors 19 are provided in the inner channel 21. The inner channel 21 enables the fluid to flow. An inflow opening 25 to the inner channel 21 and an outflow opening 25 from the inner channel 21 are formed on the first surface os1. An electrode group electrically connected to the plurality of sensors 19 is provided on a surface different from the first surface os1 of the container 18.

Abstract: An infrared imaging system comprises an optical system for forming an image of a target on an infrared detection array and an automatic focusing mechanism, wherein an output image signal of the infrared detection array is processed in a filter to extract high frequency components therefrom, The automatic focusing mechanism controls the optical system such that the high frequency components in the image signal is enhanced, In order to detect the maximum enhancement of the high frequency components, the high frequency components for the present moment and those for a past moment are compared while driving the automatic focusing mechanism, Further, the infrared imaging system is equipped with a predictive focusing control system that detects a moving speed of the target and activates the automatic focusing mechanism in advance when the moving speed of the target is fast.

Abstract: A radio environment measuring system for measuring a propagation state of radio waves includes: a fixed radio apparatus provided in a base station; a mobile radio apparatus operatively connected to the fixed radio apparatus through the radio waves; the mobile radio apparatus having a repeater unit for receiving a transmission signal from the fixed radio apparatus and sending a returned signal to the fixed radio apparatus; and the fixed radio apparatus having a transmission/reception unit for sending the transmission signal to the mobile radio apparatus and receiving the returned signal from the mobile radio apparatus, and a measuring unit for measuring the propagation state of the radio waves, for example, a propagation distance, direction and reception intensity of the radio waves between the fixed radio apparatus and the mobile radio apparatus based on the transmission signal and the returned signal.

Abstract: An infrared observing system is provided such that, after an infrared-ray emitted from an optical/scanning system is converted into an infrared-ray image signal by an infrared detector, an unnecessary high frequency component of the infrared image signal is filtered by a lowpass filter to cut off a high frequency region noise and the output thereof is represented on a display unit. Before or after the lowpass filter, a highpass filter is provided that has a reverse frequency transfer characteristic to a first inclination attenuated frequency transfer characteristic.
