Abstract

This invention describes a hermetic transfer shuttle (100) for transporting an air-sensitive material between equipment or instruments. The hermetic transfer shuttle includes a body, a lid, and a slidable pivot connecting the lid to the body. The body is formed with a cavity and a seal is located around a mouth of the cavity, so that when the lid is in a closed and an actuated position, compression of the seal separates the cavity from an ambient air. The lid has an aperture and is covered by a check valve; in the closed and actuated position of the lid, reducing a pressure above the lid actuates the check valve and causes the cavity to become evacuated; when the hermetic transfer shuttle (100) is placed inside a receiving chamber of an equipment or instrument, a vacuum in the receiving chamber will cause the check valve and the lid (110) to open.

Abstract

The present invention describes a safe-and-arm device, mechanism or assembly (160) for a projectile (100,102) equipped with a second-stage propellant (124). The second-stage propellant (124) is ignited after the projectile has been ejected out from a launcher barrel. A lockpin (190), being urged by a spring (194), is responsive to ignition of the second-stage propellant; after the lockpin (190) and spring (194) sense and respond to the second propulsion, an unbalanced rotor (164) forming part of the safe-and-arm device or assembly (160), is released to rotate from a “safe” state to an “armed” state, as the projectile continues traveling along its trajectory to a target. In one embodiment, the projectile is configured with a 40 mm cartridge containing a first propellant (122). An impact sensor may trigger an electric detonator or a point detonator may trigger a stab detonator to set off explosives disposed in the projectile.

Abstract

The present invention describes a drone interception system (10) and a streamer launcher (100) mountable on an interceptor drone (40). With this system, streamers (102) are packed in a streamers pusher (120,120a-120e); the streamers pusher, in turn, is disposed inside a cartridge case (170). In use, the streamers (102) are propelled out of the streamers pusher (120,120a-120e) and an associated launch tube (110) to generate a streamer cloud (105) in a flight path of a target propeller-driven drone (60). Contoured impeller surface (160,160c-160e) formed at an end-face of the base (150,150a-150e) of the streamers pusher interact with propulsion gases to create rotation. When the target drone (60) enters the streamer cloud (105), propellers of the target drone become entangled with some of the streamers (102) floating in the streamer cloud, thus causing the propellers to mal-function and resulting in the target drone (60) falling non-destructively to the ground.

Abstract

The present invention describes a personal slip-on slip-off wearable body temperature compress apparatus (100, 200) with which a user can set the compress to provide cool or warm energy. The temperature control setting is via a PID located in a housing (110, 210) and on a control board (160) (located inside the housing) that is wirelessly connected to the user's smartphone, whilst the shape and dimensions of an associated harness (140, 240) are made according to anthropometric data of the target user. In addition, this compress apparatus (100, 200) is comfortable and easy to wear, and unobtrusive to user's movements, with the weight of the compress apparatus being substantially transferred onto the trapezius muscles for light-weight sensation.

Abstract

This invention describes a tactical advanced robotic engagement system (ARES) (100) for combat or rescue mission by employing advanced electronics, AI and AR capabilities. In ARES, a user carries a weapon or tool (102) equipped with a hand-operable controller (150) for controlling an associated UGV (170), UAV (180) or UUV. The UGV (170) provides a ground/home station for the UAV (180). The UGV,UAV is equipped with a camera (290) to obtain real-time photographs or videos and to relay them to a heads-up display (HUD) (110) mounted on the user's helmet (104). The HUD (110) system provides intuitive UIs (132) for communication and navigation of the UGV,UAV; AR information reduces visual cognitive and mental loads on the user, thereby enhancing situation awareness and allowing the user to maintain heads-up, eyes-out and hands-on trigger readiness. The HUD (110) also provides intuitive UIs to connect up with peers and/or a Command Centre (190).

Abstract

b) for assisting a user deploy air burst munition (ABM, 10) from a rifle (20) in an intuitive manner is described. The WPU has a ballistic processor (112), wireless communication channels (120), a vibrator (130), a display (130), a mode button (150) and up/down select buttons (160, 161). After an ABM is selected and loaded into the rifle, and a deployment distance entered in the WPU, the ballistic processor calculates and outputs a time of burst T and barrel angle alpha. The barrel angle alpha is received by a sighting unit (104) and appears as a target marker. Once the rifle is tilted and/or moved so that a centre of the sighting unit coincides with the target marker, the WPU vibrates as a signal to the user to trigger the rifle.

Abstract

The present invention describes an electronic fuze operable to complement a mechanical point impact fuze. The electronic fuze includes a voltage generator circuit, micro-controller, a piezo-electric sensor, a firing circuit and a safety lockout circuit. When a projectile strikes a target at an optimum angle, the mechanical point impact fuze is activated; when the strike angle is oblique, the mechanical point impact fuze may be ineffective but the piezo-electric sensor is operable to trigger the firing circuit. The safety lockout circuit ensures the firing circuit is operative only after a predetermined delay time when an n-channel FET is turned OFF. The micro-controller also generates a TIME-OUT signal, which provides for self-destruction of a projectile that has failed to explode.

Abstract

The present invention describes methods for programming trigger time of a projectile (60) based on remaining flight time to a target (P) after the projectile (60) is airborne.
