Abstract: According to a first aspect of the invention, there is provided an object for moving through a fluid, the object comprising: an outer housing, arranged to be exposed to a hydrostatic pressure exerted by the fluid; a strain gauge, arranged to obtain an indication of the hydrostatic pressure, wherein a first part of the strain gauge is arranged to be in contact with the outer housing, such that the strain gauge is arranged to obtain an indication of the hydrostatic pressure by obtaining an indication of the strain on the housing.

Abstract: According to an aspect of the invention, there is provided a method of triggering an explosive charge of each of a plurality of munitions, the method comprising: launching a first munition, into the air, from a first gun barrel, and into water to engage with a target location, the first munition comprising a first explosive charge and a first fuze system, adapted to trigger the first explosive charge in the water, launching a second munition, into the air, from a second gun barrel, and into water to engage with the target location, the second munition comprising an second explosive charge and a second fuze system, adapted to trigger the second explosive charge in the water, the method comprising co-ordinating the timing of the triggering of the first explosive charge and the second explosive charge to establish a co-ordinated explosive event at the target location.

Abstract: Provided are methods for preparing hydrogen and solid carbon. Illustrative methods comprise providing a feedstock comprising gaseous hydrocarbons to a microwave-inert reaction vessel and/or a radio wave-inert reaction vessel. The reaction vessel has solid carbon, about 0% water and about 0% molecular oxygen inside the reaction vessel and the carbon inside the reaction vessel is operable to heat the feedstock comprising gaseous hydrocarbons. The carbon is then exposed to microwaves and/or radio waves until the solid carbon is at a temperature of at least 1200 Kelvin, thereby forming hydrogen and solid carbon. Once formed, the hydrogen and solid carbon are separated.

Abstract: According to an aspect of the invention, there is provided a fuze arming system for a submunition, comprising: a first stage, arranged to detect launch of the submunition and its associated carrier; a second stage, arranged to detect expulsion of the submunition from the carrier, and to at least partially arm a submunition fuze based on such detection; wherein the second stage is unable to at least partially arm the submunition fuze without the first stage detecting launch of the submunition and its associated carrier.
