US Patent:

7040319, May 9, 2006

Filed:

Feb 22, 2002

Appl. No.:

10/087866

Inventors:

Mark E. Kelly - League City TX, US
Donald R. Pettit - Houston TX, US

Assignee:

The United States of America as represented by the National Aeronautics and Space Administration - Washington DC

International Classification:

A61M 16/00
A62B 7/00
F16K 31/02

US Classification:

12820422, 12820523, 12820525

Abstract:

Method and apparatus are disclosed for monitoring an oxygen partial pressure in an air mask and providing a tactile warning to the user. The oxygen partial pressure in the air mask is detected using an electrochemical sensor, the output signal from which is provided to a comparator. The comparator compares the output signal with a preset reference value or range of values representing acceptable oxygen partial pressures. If the output signal is different than the reference value or outside the range of values, the air mask is vibrated by a vibrating motor to alert the user to a potentially hypoxic condition.

US Classification:

408222, 408 1 R, 408225, 470199

Abstract:

Methods and tool for simultaneously forming a bore in a work piece and forming a series of threads in said bore. In an embodiment, the tool has a predetermined axial length, a proximal end, and a distal end, said tool comprising: a shank located at said proximal end; a pilot drill portion located at said distal end; and a mill portion intermediately disposed between said shank and said pilot drill portion. The mill portion is comprised of at least two drill-tap sections of predetermined axial lengths and at least one transition section of predetermined axial length, wherein each of said at least one transition section is sandwiched between a distinct set of two of said at least two drill-tap sections. The at least two drill-tap sections are formed of one or more drill-tap cutting teeth spirally increasing along said at least two drill-tap sections, wherein said tool is self-advanced in said work piece along said formed threads, and wherein said tool simultaneously forms said bore and said series of threads along a substantially similar longitudinal axis.

International Classification:

A47G 19/22

US Classification:

2207105, 220719, 220DIG 13

Abstract:

A beverage cup comprised by an open top and at least one channel defined by a corner with an acute angle so placed that the channel runs along the cup side from the cup bottom to the cup rim. In the absence of significant gravitational force as found in microgravity, weightless or weightlessness of spacecraft or the International Space Station, capillary forces between the beverage and the cup wall allow the beverage to creep along the channel and be in near proximity to the open cup rim. Lips placed at or near the channel at the rim can readily sip, drink, and consume the beverage without the need for a straw and without undue spillage for normal drinking motions including toasting. The channel conducts the beverage via capillary forces from the bottom of the cup to the rim until the beverage has been consumed.

International Classification:

A47G 19/22
B65D 25/14

Abstract:

A capillary beverage cup comprises a continuous interior corner extending from a lip interface into an inner cavity of the capillary beverage cup, the continuous interior corner comprising an acute included angle which tapers continuously as the interior corner approaches the lip interface. The capillary beverage cup provides a continuous capillary force on the liquid contained by the cup, allowing for complete withdrawal of fluid from the cup in low or near zero gravity environments, while enabling the cup to have an open top, allowing for aromatics to be experienced by a user while drinking with reduced concerns of spilling or release free-floating spheres of liquid in the low-gravity environment.
