A luminescent archery target enabling target shooting in low light conditions. At least a portion of the target is formed from a material that glows in the dark for long durations, such as a strontium-based luminescent composition. Example target configurations include a non-luminescent core and an outer layer applied over at least a portion of the core, wherein the outer layer includes the luminescent material. The target can be configured as a three-dimensional block, as a model of a game animal, or in other shapes and sizes.

The present disclosure is directed to an artificial skin including: a radar absorbing layer; a conductive layer comprising at least one material selected from the group consisting of a semiconductive oxide deposited onto a substrate and an electrically conductive polymer, wherein the substrate is in contact with the radar absorbing layer, and wherein the artificial skin has a reflection coefficient substantially equal to a human skin reflection coefficient, the human skin reflection coefficient being determined at an electromagnetic radiation frequency ranging from 1-500 GHz. A human phantom composed of the artificial skin and methods of using the human phantom are also disclosed.

There is provided an inflatable dummy target comprising a chassis wrapped with a sheet. The chassis can be formed by individual inflatable ducts and can comprise at least two ring-shaped ducts interconnected by one or more elongate ducts. The inflatable dummy target can further comprise rigidizing ducts. The inflatable dummy target geometry can be conical, cylindrical, etc. Optionally, the inflatable dummy target can comprise several attached axi-symmetrical sections, wherein each section has a chassis wrapped with a sheet, the chassis formed by individual inflatable ducts. Optionally, the shape of each section can be selected from the group consisting of conical, frustoconical and cylindrical forms.

A modular underwater vehicle includes a hull having a series of modular sections, defining an interior housing, a propulsor coupled to a stern of the hull, a series of control surfaces coupled to the propulsor or the stern of the hull, and a power supply, a processor, and a nonvolatile memory device in the interior housing. The nonvolatile memory device has instructions stored therein which, when executed by the processor, cause the processor to supply power from the power supply to drive the propulsor and to actuate the plurality of control surfaces. At least one modular section of the series of modular sections is detachable.

Before a person can use any weapon, such as a gun or a rifle, effectively, the sight must be aligned to the barrel through a zeroing process. An improved zero target is developed which is inexpensive and applicable to many different weapon sight scenarios. By making a universal zero target, users need only a single target eliminating the need for procuring and storing various targets. Additionally, the multi-sight target eliminates the need for field expedient zeroing solutions. The product saves both time and money and improves the results for weapon users.
