Abstract

The invention relates to a stroboscopic light-emitting device (1) for locating purposes, comprising a housing (10) provided with an infrared light emitter (20), a stabilised power supply module (40) contained in the housing and coupled to an electric accumulator (50), and a control module (30) also contained in the housing (10) and capable of controlling the duration and frequency of emission of the emitter (20) so as to generate a strobe light signal, characterised in that the light emitter consists of an infrared thermal emitter (20) comprising a heating element (21) through which an electric current is able to flow such that it causes the heating of the element and the emission of infrared thermal radiation.

Abstract

The invention relates to an aircraft-towed device, comprising a support structure (10) that is substantially flat when deployed; a transmission antenna (14) mounted on the support structure, having a conductor wound in a loop near the edges of the support structure; an attachment element (30) configured for mechanically and electrically coupling the towed device to a towing cable (20); and an attitude-correcting pole (24) arranged between the attachment element and the support structure, and configured to assume a vertical position when the device is towed. The towed device comprises power conversion circuitry (52, 54) coupled between the attachment element and the transmission antenna, configured to power the transmission antenna (14) at a high current and a low voltage from a higher voltage and lower current conveyed through the towing cable; and the power conversion circuitry is mounted (60) at the bottom of the attitude-correcting pole.

Abstract

The invention relates to a tow hitch assembly comprising an aircraft (P), a towing cable (60) and a towed device (1), the aircraft pulling the towed device by the towing cable. The invention can be used to attach and tow a large antenna (31) being used to take measurements, maintaining a stable horizontal or even vertical attitude using automatic attitude correcting mans (10) as well as particularly ingenious male and female (40, 50) attachment means. In addition, an electrical connection can be provided between the towed measurement means (31) and the aircraft (P). Such a tow hitch assembly is particularly suitable for use in obtaining parameters invaluable in the prospecting of natural resources or in identifying underground voids.
