International Classification:

A61F 604

US Classification:

128842, 128844, 128918

Abstract:

A contraceptive sheath can provide extra leak protection by forming at least one latex film over the bulbous closed end of a latex sheath liner. A transparent elastic covering overlies the sheath outer surface to seal the latex films against separation from the latex liner.

Assignee:

The United States of America as represented by the Secretary of the Army - Washington DC

International Classification:

B64D 1702

US Classification:

244145, 244142

Abstract:

A parachute cluster assembly includes a first round parachute having a first canopy of radially extending first gores, and a second round parachute having a second canopy of radially extending second gores. Adjacent ones of the first gores are joined along a line to adjacent ones of the second gores to fix the first canopy to the second canopy along the line. The first canopy defines a first slot spaced from but neighboring the first gores joined along the line, and the second canopy defines a second slot spaced from but neighboring the second gores joined along the line. The first and second slots are disposed on a same side of the cluster assembly.

Inventors:

Calvin K. Lee - Needham MA, US

Assignee:

United States of America as represented by the Secretary of the Army - Washington DC

International Classification:

B64D 17/52

US Classification:

244149, 244142

Abstract:

A parachute system has a canopy, suspension lines that extend from the canopy skirt to a confluence point, and a center line that is attached to and between the apex of the canopy and the confluence point. A single reefing line cutter is attached to the center line and is activated after a predetermined amount of time has elapsed. A first reefing line extends through a first group of reefing rings wherein one end of the first reefing line is attached to the single reefing line cutter and the opposite end is attached to the canopy skirt at a first predetermined location. A second reefing line extends through a second group of reefing rings that is opposite the first group of reefing rings. The second reefing line has one end attached to the single reefing line cutter and an opposite end attached to the canopy skirt at a second predetermined location that is across from the first predetermined location. The canopy opens to an initial circumference that is determined by the summation of the lengths of the first and second reefing lines. When the reefing line cutter is activated, the reefing line cutter releases the first and second reefing lines so as to allow full inflation of the canopy.

Assignee:

The United States of America as represented by the Secretary of the Army - Washington DC

International Classification:

B64D 17/58

US Classification:

244147

Abstract:

A parachute system having a parachute canopy having a skirt, and a plurality of gores spaced about the skirt. The plurality of gores is defined by first and second groups of gores. The parachute system includes a slider having a plurality of through-holes, a line loop attached to the slider, a first reefing line extending through the first group of gores and having a pair of ends attached to the line loop, and a second reefing line extending through the second group of gores and having a pair of ends attached to the line loop. A corresponding group of suspension lines passes through a corresponding through-hole in the slider. Each suspension line in each group of suspension lines is attached to a corresponding gore. A single reefing line cutter is engaged with the line loop and configured to cut the line loop after a predetermined amount of time has elapsed so as to release the reefing lines and allow the slider to slide down the suspension lines.

Calvin Spencer Lee - Northridge CA, US

Assignee:

Wing Pow International Corp. - Chatsworth CA

International Classification:

A61H 1/00

US Classification:

601 46, 600 38

Abstract:

A vibratory massaging device having a spaced plurality of proximity sensors distributed on a massaging surface of the device, and a control circuit operative for controlling vibratory intensities in response to activation of particular ones of the sensors being close to a user's body parts being massaged. The device can be configured as a dildo, including both main and secondary vibrators, the secondary vibrator being within an arm portion that is configured for clitoral stimulation. At least one of the vibrators is automatically driven at increased intensity as penetration increases.

International Classification:

G06Q 90/00

US Classification:

705022000

Abstract:

Methods and systems for predicting out-of-stock occurrences and for assigning root causes to out-of-stock occurrences are described. In one implementation, inventory data and point of sale data are collected. An expected lost sales value is determined. A true demand is determined based on the point-of-sale data and the expected lost sales value. A probability of an out-of-stock occurrence is determined based on the inventory data. In another implementation, an out-of-stock occurrence is identified. The out-of-stock occurrence is classified, and one or more root causes are assigned to the out-of-stock occurrence.
