A system and method for adaptation of a radar receiver in response to frequency drift in a transmission source is disclosed that utilizes a stable local oscillator established at a single, non-fluctuating frequency and compensates for transmission frequency fluctuation in the signal processor module. A capacitor composed of a lower electrode, a capacitor dielectric film made from a high dielectric constant material or a ferroelectric material and an upper electrode successively formed in this order above the semiconductor substrate is provided on the adhesion layer. After the probe, slidably disposed within the tubular body, is positioned through the blind hole to be measured, the grooved insert is slid forward inside the tubular body, surrounding the probe, and pushing the probe sideward, towards the blind hole wall. The display console can remotely interface with a cellular telephoneBluetooth enabled device in order to receive remote instructions in order to open the door of the pet cage.
