Abstract: Targets for use in training personnel in the operation of thermal imaging systems are described, the targets include: an internal cavity; an electrically powered heat source; the heat source is arranged to introduce heat to the internal cavity to cause warming of the target to thereby generate a heat signature.

Abstract: A pin mount system for releasably mounting a sports net to a ground surface, for example a hockey net to an ice surface. The sports net includes at least one post having an end. The pin mount system includes: a pin having a proximal end and a distal end, the proximal end for positioning within the post, a resilient member such as a spring coil in compression to normally exert an extensive force to the pin to extend the distal end of the pin past the end of the post, and a handle operably connected to the pin to retract the pin against the resilient member. The pin is releasable from the ground surface in response to an amount of force applied to the sports net, and the sports net stays in place when minor force is applied, for example.

Abstract: An ice maker for creating a layer of ice on a cooled surface, is disclosed. The ice maker has a source of de-gassed water, which may be de-gassed by being heated. A pump to pressurize the de-gassed water is provided and the water is passed to a sprayer hydraulically connected to the pump. The sprayer has nozzles sized and shaped to convert the pressurized water into a fine de-gassing droplet spray directed at the cooled surface. The droplets are sized to substantially freeze on contact with the cooled surface. In one embodiment a microprocessor is provided to change the volume sprayed according to the speed of the ice maker to ensure an even coat of ice is layed down.
