A method for deploying a reconnaissance sonde, including the steps of: incorporating at least one environmental sensor and an associated communication device into a robust, aerodynamically efficient casing; deploying the sonde by imparting a spin and a directional velocity to the casing, sufficient to carry the sonde into a region of interest; and establishing communication with the communication device, thereby enabling data from the sensor(s) to be transmitted to a remote location. A sonde for remote data collection is also provided, including at least one environmental sensor, an energy source and communication means. The sonde is generally shaped as a discus or saucer, a clay pigeon or skeet, for deployment by applying a spin and directional velocity to the sonde.

Autonomous reconnaissance sonde, and method for deployment thereof

A passive object detection system () comprises first and second antennas () and a processor (). The first antenna () is adapted to receive a signal transmitted by a mobile telephone base station; the second antenna () is adapted to receive the signal transmitted by a mobile telephone base station () after it has been reflected off an object () and the processor compares the signal received from the mobile telephone base station with the signal reflected from the object to derive speed or position information relating to the object therefrom.

There is provided an autonomous off-board defensive aids system ( ) for use with a host craft ( ), for example, with combat aircraft or submarines. More particularly, the host craft ( ) deploys a plurality of controllable off-board units ( ) to counter an offensive threat or to engage in autonomous offensive actions. The controllable off-board units ( ) implement active stealth facilities: each off-board unit ( ) having a receiver unit for detecting impinging detection pulses, for example radar or sonar pulses, and a transmitter unit for generating an artificial detection pulse profile, for example &ldquo;spoofing&rdquo; or masking the presence of the host craft. The controllable off-board units are of two types: tethered ( ) and free moving ( ). The off-board units ( ) can have conventional propulsion apparatus, for instance, propellers, rockets or jets. Off-board units ( ) each have control apparatus which allows the off-board units ( ) to co-operate. General commands are conveyed to the control apparatus by control cabling provided in the tether cable ( ).

A catheter tracking system for tracking and monitoring a position of a catheter head within the human or animal body includes a self-referencing catheter. The self-referencing catheter includes an inner core, an outer sheath having a plurality of sensors and a cage for fixing the outer sheath at a predetermined position. The sensors receive signals generated by the transducer so as to produce measurement signals in accordance with a time of propagation of the signals for determining the position of the head relative to the outer sheath.
