Abstract: An expanding plunger rod (100) for a syringe (50). The expanding plunger rod is configured to transition from a packaged configuration for packaging to an expanded configuration for operation. The expanding plunger rod comprises a substantially cylindrical outer sleeve (110) having a closed-off bottom end (108) and an open upper end (111). The expanding plunger includes an inner rod (114) having a lower end (138) and an upper end (140). The inner rod is slidably disposed coaxially within the outer sleeve. In the packaged configuration, the inner rod is nested within the outer sleeve. In the expanded configuration, the inner rod is disposed substantially axially above the outer sleeve, and the inner rod is configured to lock axially in place so as to prevent transition from the expanded configuration to the packaged configuration.

Abstract: An enclosure for carrying an adjustable payload. The enclosure is beneficially used on a rotorcraft blade or other similar structure. The enclosure has a first element having a first flange and an upper element. The first element has an upper surface which has a first angle with respect to a lower surface of the first flange in a direction extending from an inboard direction to an outboard direction. The upper element has a lower surface which has a second angle with respect to an upper surface of said upper element in a direction extending from an inboard direction to an outboard direction, the lower surface being in contact with the upper surface of said first element, the second angle being in a direction which is opposite to the direction of said first angle. The first element and the upper element define a cavity for holding a payload.
