Title: Apparatus for detecting enuresis in a patient
Inventor: SMITH TOBY E
IPC: G01N27/04
Filed: 2000-07-21
Granted: 2004-05-27
Abstract: This invention relates generally to patient monitoring systems and more particularly concerns devices and systems used to monitor bed patients in hospital or other care-giving environments. In accordance with a first aspect of the instant invention, there is provided a wetness detector for use in patient monitoring situations and which is adjustable in its degree of sensitivity to wetness. It contains at least two conductive regions placed on a non-conductive base and which are preferably separated laterally by some distance. Isolated electrical leads are attached to each conductive region. Electrical current passes much more readily between the two conductive regions when an electrolytic solution such as urine is present within the switch, thereby making it possible for a separate electronic monitor to determine when wetness is detected.

Abstract: PROCESS FOR PRODUCING PREFORMABLE       CONTINUOUS STRAND MATS ABSTRACT OF THE DISCLOSURE A process for forming a continuous strand preformable mat is disclosed which consists of applying a binder matrix material which includes a thermosetting polyester binder material and a thermoplastic polyester binder to the continuous strand mat.  The mat is heated such that the thermosetting binder material cures and hardens while the thermoplastic binder material softens and flows around strand intersections.  The mat is thereafter cooled in order to solidify the thermoplastic polyester material of the binder matrix for additional handling for packaging and for subsequent handling by the customer. The preforms are made by heating the mat to oven 93.3°C (200°F), placing in a cold mold, and then closing the mold to form and solidify the mat shape.

Abstract: The oil level is controlled between the main gear shift chamber of a transmission and the final reduction gearing/differential chamber by pumping air from the differential chamber into the main gear chamber. The increased air pressure then forces oil back into the differential chamber. The air pump preferably is a simple piston pump driven by a cam on one of the drive shafts on the main transmission chamber. An oil film is provided in the passage connecting the main transmission chamber to allow flow of oil between those chambers, while preventing the flow of air.

Abstract: ABSTRACT OF THE DISCLOSURE      This invention provides a novel speech coding system which recursively executes a filter-applied "Toeplitz characteristic" by causing a drive signal (i.e., an excitation signal) to be converted into a "Toeplitz matrix" when detecting a pitch period in which distortion of the input vector and the vector subsequent to the application of filter-applied computation to the drive signal vector in the pitch forecast called either "closed loop" or "compatible code book" is minimized.  The vector quantization method substantially making up the speech coding system of the invention is characteristically used by the system.

Title: Rapid miosis with control of intraocular pressure
Inventor: MCKINZIE JAMES W
IPC: A61K31/22
Filed: 1991-01-14
Granted: 2002-07-16
Abstract: Quick miosis with 24 hour control of intraocular pressure of patients undergoing extracapsular cataract extraction surgery is achieved by applying to the eyes of the patient during surgery acetylcholine as a first miotic agent and carbachol as a second miotic agent. Acetylcholine provides quick miosis while carbachol enhances the miotic effect while providing post-surgery control of intraocular pressure. The two miotic agents can be dissolved in a common saline carrier. The two agents can be combined in a unit dosage package by disposing acetylcholine in powder form in a first compartment and a solution of carbachol in a second compartment. The combined miotic agent of the invention is especially useful when substances which raise IOP such as viscoelastic agents are used during ocular surgery and/or with sensitive patients who enter the surgery with elevated pressure such as those suffering from glaucoma.

Abstract: An inhalation device is provided for use with an aerosol container (208) having a body portion and a discharge stem (216) movable with respect to the body portion from a rest position in which discharge is prevented to an operative position in which discharge takes place. The device has a housing (202) for the inhalation device, and an outlet (204) provided in the housing through which a patient can inhale. A restraining and pressure-sensing member is provided in the form of a resiliently flexible plate (234). The plate has a first position in which it prevents relative movement between the discharge stem and the body portion to the operative position and a second position in which it permits such movement. The plate senses when a reduced pressure is produced through inhalation by the patient and moves from the first position to the second position in response thereto.

Granted: 1996-01-30
Abstract: In an electronic imaging system in which a document is electronically imaged on a platen by a scanning electronic imager, a document for which manual handling is desired is manually positioned in a special manual registration position on the platen in which one corner of the document underlies a unique signal generating optical indicia positioned over that cornerof the platen. Preferably, this optical indicia is a uniquely numbered bar code pattern on a stationary baffle, or other overlying surface, upstream of the document feeder platen transport, and preferably located in a start of scan area. The electronic imager is at least partially optically occluded from reading thatunique bar code pattern by a document present in that manual registration position. (A document for which automatic feeding is desired may be placed in a document feeder and fed thereby onto the platen into a different registration position in which no portion of that document is interposed between that bar code and the imager.) The imager can read, or not read, that unique bar code to provide a unique control signal to control the document feeder and/or provide other desired functions, such as indicating that a previously manually placed document was left on the platen.

Abstract: A potassium salt useful in the production of certain N-substituted alkyl or arylalkyl thionitroethenamines is produced by the reaction of the dipotassium salt of a 2-nitrodithio aliphatic acid such as 2-nitrodithio acetic acid with branched chain primary alkylamines, secondary alkylamines, arylalkylamines or heterocyclic alkylamines such as dimethylamine, pinacolylamine, benzylamine or piperonylamine, thereby converting one only of the KS-groups to an alkylamine group. The resulting monopotassium salt may be alkylated or arylalkylated to produce an N-substituted alkyl or arylalkyl thionitroethenamine. This compound may be reacted with a suitable amine to produce compounds containing the pharmaceutically active grouping -NHC( = CHNO2)NHX, wherein X represents an alkyl, arylalkyl or heterocyclic alkyl group.

Title: Improved helmet
Inventor: FEULING JAMES J
IPC: A42B3/04
Filed: 1991-11-19
Granted: 2000-06-27
Abstract: The disclosure is directed to an improved aerodynamic helmet. The helmet has a continuous aerodynamic curvilinear front, side and top surfaces whereby the fluid flowing over and around the sides of the helmet flows in a substantially continuous flow direction from the forward curved area aft of a straight area at the greatest width or largest transverse dimensions of the helmet after leaving the surface influence thereof. The continuous transverse surface around the outer periphery of the helmet at or slightly aft of the greatest width area is provided with a fluid flow termination surface or trailing edge causing the normal direction of the fluid flow around the helmet to break loose from the surface of the helmet and continue in substantially the same direction after passing the termination or trailing edge thereby preventing turbulence to the flow rather than allowing the fluid flow to follow the surface and flow around a portion of the smaller dimension back surface of the helmet before separating therefrom which creates turbulence behind the helmet and unwanted lift thereto. The improved helmet lowers wind drag compared to conventional helmet by about 40%.
