Filed:

Feb 27, 2013

Appl. No.:

13/778215

Inventors:

John Dale - Moorestown NJ, US

International Classification:

A63F 9/10

US Classification:

273156

Abstract:

A multi-piece, two-dimensional puzzle whose solution involves the matching of multiple-symbol, piece-matching indicia located along each edge of a two-faced puzzle piece with corresponding multiple-symbol, piece-matching indicia located along edges of adjacent abutting pieces. The multiple-symbol, piece-matching indicia is not shared by adjoining puzzle piece edges. Further, each piece is provided with unique piece-identifying indicia on both of its faces. Together, the matching of multiple-symbol, piece-matching indicia of adjacent tile edges, coupled with signaling of solutions as suggested by observation of the unique piece-identifying indicia leads a player to solution of the puzzle.

Appl. No.:

6/300875

Inventors:

John R. Dale - Pennsburg PA
Malcolm I. Dickinson - Chalfont PA

Assignee:

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

International Classification:

H04B 159

US Classification:

367 4

Abstract:

A novel low cost air-launched sonobuoy having a spherical housing of a liweight semi-rigid foam housing encapsulated the electronic components. The housing includes recesses for receiving a hydrophone and cable pack, and for inserting D-size batteries just prior to launching. A vertical antenna is wrapped around the housing and prevents the pack from deployment until the sonobuoy is charged with the batteries and immersed in water. The free end of the antenna is released and unwraps to permit deployment of the hydrophone and cable pack. The sonobuoy is stored without the batteries in a sealed moisture-proof envelope which can be easily torn open and removed when desired.

International Classification:

A61M 700

US Classification:

604 40

Abstract:

A pharyngeal suction device for use during cardiopulmonary resuscitation and trauma stabilization. A hollow wand is provided with peripheral recesses which act as safety vents when the wand is used without the safety tip. The safety tip is attached to the wand in either of two orientations and secured at the peripheral recesses. A safety tip outlines a hemispherical surface and defines three passages which communicate with the interior of the wand.

International Classification:

G01S 1500

US Classification:

367 4

Abstract:

An underwater acoustic surveillance system for obtaining data related to nd sources of interest in a large geographic area over long periods. A number of acoustic sensors are dropped from an aircraft for placement on the bottom of the sea at known locations. Each sensor automatically deploys a parachute to retard the descent in the air. A parachute riser weak link releases the parachute upon immersion in the water, and a latch operable at a preselected depth allows cylindrical staves to spread apart and form a stable platform on the bottom from which a hydrophone suspends and an acoustic projector tethers. A web-like flow shield unfolds between adjacent staves of the platform to provide additional retardation during the descent in the water and to reduce hydrophone noise due to water currents at the bottom. A water-activated battery at the lower extremity of each stave ensures upright orientation of the sensor when it reaches the bottom, and provides electrical power for storing and transmitting acoustic data. Acoustic data stored in the sensor is retrieved by a sonobuoy deployed on the surface near the previously recorded location of the sensor. An r. f.

Appl. No.:

Inventors:

John R. Dale - Pennsburg PA

Assignee:

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

International Classification:

B63B 2152

US Classification:

441 30

Abstract:

An air launchable sonobuoy having two separate liquid chemicals which react pon mixing to form an expanded, rigid foam flotation device. Upon deployment in the air, windflaps release a preloaded plate within a submersible housing and urge the chemicals to mix and foam in an elastic envelope. After water impact, an orifice in the housing permits water to fill the voids at a rate sufficient to allow the housing to remain afloat until foaming and erection of an antenna within the envelope is complete. As the envelope expands, a latch releases it from the housing and permits the housing when flooded to sink to the desired depth determined by the payout length of a cable within the housing connected to the flotation device.

International Classification:

H04B 159
B63B 2152

US Classification:

367 4

Abstract:

A sonobuoy suspension system is disclosed wherein a spring motor having a substantially constant output torque is mounted within an upper sonobouy unit secured to a buoyant flotation member. Formed from a coiled band, constant force extension spring wound in opposite directions about a pair of rotatable drums so that the spring is extended tangentially therebetween, the motor is coupled to a lower sensor unit by a non-compliant suspension cable for supporting the sensor unit at a predetermined underwater depth substantially isolated from the wave affecting the upper unit and flotation member.
