Abstract: Distilling tube apparatus for converting salt water such as sea water into fresh water is provided.  The apparatus includes a first tube through which a feed stream of heated salt water is caused to flow,  the first tube being constructed of a porous material which is both water-vapor permeable and liquid water impermeable, which tube allows water vapor to permeate through its walls thereof when heated salt water flows therethrough, the vapor then condensing outside of the first tube upon cooling of the vapor thereat.   This first tube is preferably constructed of porous, expanded polytetrafluoroethylene.   A  second tube  oriented  in generally parallel relationship and in close proximity to the first tube is provided through which cooling water is caused to flow. The cooling water is maintained at a temperature lower than that of the heated salt water,  thereby resulting in a lowering of the temperature of the surroundings of the second tube and providing an enhanced driving force for distillation of the salt water.  A third housing tube is provided which houses both the first tube and the second tube within its interior.  This housing tube has a plurality of spaced apart openings in the wall thereof to permit fresh water which has condensed externally to the first tube and within the housing tube to flow through these openings and thence outwardly of the distilling tube apparatus.

Title: Terrain elevation database convergence model
Inventor: GJULLIN ROBERT M
IPC: G06F17/30
Filed: 1995-01-17
Abstract: A convergence model is shown and described for accommodating variation in data post spacing in a digital terrain elevation database (DTED) based on longitude and latitude address values for data posts. Under such a database structure, data posts lying along lines of latitude vary in spacing according to latitude, and converge at the poles with zero spacing therebetween. To scan a circular region of data posts relative to a given data post, e.g., a threat installation this variation in data post spacing is considered by appropriately scaling sample step spacing along radials traversed in executing a radial spoke scan pattern. In this manner, a circular region of data posts surrounding a given data post may be sampled using simple, dedicated hardware despite this variation in data post spacing.

IPC: G10L15/14
Filed: 1996-01-29
Abstract: In a statistical based speech recognition system, one of the key issues is the selection of the Hidden Markov Model that best matches a given sequence of feature observations. The problem is usually addressed by the calculation of the maximum likelihood, ML, state sequence by means of a Viterbi or other decoder. Noise or inadequate training can produce an ML sequence associated with a Hidden Markov Model other than the correct model. The method of the present invention provides improved robustness by combining the standard ML state sequence score (416) with an additional path core (418) derived from the dynamics of the ML score as a function of time. These two scores, when combined, form a hybrid metric (420) that, when used with the decoder, optimizes selection of the correct Hidden Markov Model (422).
