摘要:
A protection system includes a net made of flexible, low breaking strength intersecting lines connected at nodes. A frame supports the net and spaces the net from a vehicle and/or structure. Hard points are disposed at least at select net nodes and feature a multi-sided body with a cavity therein behind a front face thereof. The body includes a lip extending into the cavity. A protrusion extends outwardly from the front face. A tapered plug is received in the cavity and includes a ledge engaged by the lip locking the plug and a net node in the cavity and securing the hard point to the net node in a pivotable fashion.

A method of designing an RPG. A computerized model is created of a shield mesh opening with lines of a net intersecting at nodes and with hard points positioned at least at select nodes. The effectiveness of the mesh opening at a plurality of obliquity angles is determined. In the model, a change is made to the size of the mesh opening and the effectiveness is determined again at a plurality of different obliquity angles. Iterations of this process allow an optimal mesh opening size to be determined for a threat such as an RPG.

A shield system for an ordnance having a fuse sensitivity includes a frame and a flexible net subsystem supported by the frame. Chords of net material intersect at nodes forming mesh openings and a hard point is attached to at least select nodes. The net material has a breaking strength such that a chord will break upon impact of an ordnance fuse with the chord for a predetermined percentage (e.g., 100%) of ordnance fuse impacts.

A syringe assembly for use with an infusion pump having a drive piston. The syringe assembly comprises a substantially hollow syringe housing and a plunger axially movable within the syringe housing to dispense a fluid therefrom. The plunger has a body with a portion thereof configured to engage a radially elastic member associated with the drive piston such that the plunger is releasably axially secured relative to the drive piston.

A voltage level shifting device for translating a lower operating voltage to a higher operating voltage includes a first input node coupled to a first pull down device and a second input node coupled to a second pull down device. The second node receives a complementary logic signal with respect to the first input node, the first and second input nodes associated with the lower operating voltage. A first pull up device is in series with the first pull down device and second pull up device is in series with the second pull down device, with the first and second pull up devices coupled to a power supply at the higher operating voltage. An output node is between the second pull down device and the second pull up device, the output node controlling the conductivity of the first pull up device. A clamping device is in parallel with the first pull up device, and configured to prevent the second pull up device from becoming fully saturated.
