Abstract: A submunition dispensing system is disclosed which includes inflatable bladders expandable from collapsed to inflated conditions in response to fluid pressure. The bladders are mounted in cavities of a carrier frame underlying subpacks of submunitions. The bladders lie adjacent to the support and central structures of the frame defining the cavities. Each bladder can be configured to have either an unpleated or a pleated configuration in the collapsed condition. The bladder can also be configured for expansion to an overall constant diameter outer shape or to a generally conical outer shape in the inflated condition. Expansion to the conical shape imparts a velocity gradient to the subpack. The dispensing system also includes retaining assemblies for releasably retaining the subpacks in the cavities against the collapsed bladders and a gas generator disposed in a passage of the central structure of the carrier frame.

Abstract: A device for indicating a pressure drop or low pressure condition in a tire detects a pressure drop and makes an acoustic signal in response to the detection of the pressure drop. The device can include a strut for intermittently contacting a wall of a tire, a striker attached to the strut for striking the wheel rim, and a pressure-activated latch for preventing the strut from contacting the wall or the tire when the pressure in the tire is above a predetermined value by holding the strut tangent to the wheel rim.
