An oil well improvement system having an intrusion detection and response subsystem that provides practical capability to defend offshore drilling platform from surface or subsurface terrorist threats/attacks utilizing modified low-cost off-the-shelf equipment and processor programs. The subsystem processes acoustical and/or RF sensor data to determine contact positions, rates, projected future positions, identification, threat analysis and recommends appropriate soft/hard kill counter measures and further provides control of those countermeasures.

In an object detection apparatus, a first region definition unit defines a first object region including a first detection point representing a relative position of a first object detected based on detection information from the radar. A second region definition unit defines a second object region including a second detection point representing a relative position of a second object detected based on a captured image from a monocular camera. A learning status acquisition unit acquires a learning progress status to estimate a position of FOE on the captured image. If there is an overlap of the first and second object regions, a determination unit determines that these objects are the same object. The second region definition unit sets a length of the second object region in a depthwise or vehicle-lengthwise direction representing a direction of the second detection point with respect to the reference point depending on the learning progress status.

A system for three-dimensional animal tracking in laboratory conditions is proposed. A mobile device that has one infrared and one ultrasonic sensor, equipped with memory and/or radio transmitter, is attached to a moving creature. One compact stationary box is placed in the vicinity; it emits a pre-determined sequence of short infrared pulses, short ultrasonic signals and two planar, radially emitted light beams that move through the area of interest with constant angular speed in two orthogonal directions. The mobile device receives two angular coordinates in the form of two time intervals between an infrared pulse and the next two orthogonal planar beam receptions, and it receives one linear coordinate in the form of the time interval between an infrared pulse and the next ultrasonic signal reception, taking into account the speed of sound in the air. The ultrasonic emitter is driven by a pulse-width modulated signal to make it undetectable by animals.
