Patent number: 11925465Abstract: Uroflowmeters and methods for processing data generated therefrom are disclosed. In one aspect, the uroflowmeter is a handheld device. The uroflowmeter includes a handle, a flow chamber coupled to the handle, and a sensor associated with the flow chamber that detects a parameter of urine received in the flow chamber. The uroflowmeter may include both reusable and disposable components. As a uroflowmeter it can identify and record data corresponding to the rate of flow over the measured duration of a void of urine, but may also timestamp the voiding act and communicate the data to an external data collection center for additional analysis and incorporation into a comprehensive voiding report or voiding diary.Type: GrantFiled: March 8, 2019Date of Patent: March 12, 2024Assignee: ClearTrac Technologies, LLCInventors: Brent Laing, John Green, Paul R.

Publication number: 20090221492Abstract: Recombinant Factor IX characterized by a high percentage of active protein can be obtained in the milk of transgenic animals that incorporate chimeric DNA molecules according to the present invention. Transgenic animals of the present invention are produced by introducing into developing embryos DNA that encodes Factor IX, such that the foreign DNA is stably incorporated in the DNA of germ line cells of the mature animal. Particularly efficient expression was accomplished using a chimeric construct comprising a mammary gland specific promoter, Factor IX cDNA that lacked the complete or any portion of the 5?-untranslated and 3?-untranslated region, which is substituted with a 5-? and 3?-end of the mouse whey acidic protein gene. In vitro cell cultures of cells explanted from the transgenic mammal of the invention and methods of producing Factor IX from such said culture and methods of treating hemophilia B are also described.Type: ApplicationFiled: August 29, 2008Publication date: September 3, 2009Inventors: William H.

Patent number: 7552074Abstract: A network for managing account addresses (such as for credit card accounts) where correspondence and other communications mailed to account holders may have different purposes (e.g., credit card statement, new credit card, marketing correspondence). The network has a database for storing addresses and a database management system for retrieving those addresses. A default address is provided when there is no address stored in the database for the intended purpose of a mailing. The addresses are in categories, with each category associated with a different communication purpose, and with multiple addresses in each category. The multiple addresses within each category may be permanent, temporary or repeating. If temporary or repeating, effective start and end dates are associated with the addresses. There may be multiple cardholders for each account, in which case the address categories (and multiple addresses within each category) are associated with each cardholder.Type: GrantFiled: August 3, 2006Date of Patent: June 23, 2009Assignee: First Data CorporationInventors: Heather Bruce, Doug Stewart, Margaret A.

Patent number: 6970900Abstract: An optical system utilizing phosphors to perform mathematical operations without the direct or necessary use of an electronic component or electrical power source is disclosed. The luminenscent and quenching properties of phosphors are combined with at least one first-order relaxation subsystem such that when the optical system achieves equilibrium, it will have performed certain mathematical operations. The precise mathematical operation to be performed is determined by controlling the materials utilized, light inputs, and certain variables within the optical system.Type: GrantFiled: January 22, 2002Date of Patent: November 29, 2005Assignee: The United States of America as represented by the Secretary of the ArmyInventor: John L.

Patent number: 6774996Abstract: A method and an apparatus for measuring the density variations, static and dynamic, in substances that are at least partially transparent to electromagnetic waves is disclosed. A special birefringement crystal phase shifting assembly encodes the angle of incidence resulting from the refractive effects of the electromagnetic waves having passed through a density variation. The angle of incidence is encoded as a poralization phase shift. Specifically, the poralization phase shift is between the ordinary and the extraordinary rays. That poralization phase shift has a known and definable relationship to the gas density experienced by the electromagnetic wave during its path.Type: GrantFiled: June 11, 2002Date of Patent: August 10, 2004Assignee: The United States of America as represented by the Secretary of the ArmyInventor: John L.

Patent number: 6348998Abstract: Polarization phase plate Assembly comprises at least two uniaxial crystal plates which are identical to each other in structure and dimension and a retarder plate sandwiched between the two uniaxial crystal plates. Initially the optic axes of the crystal plates are aligned to be parallel with each other. Then the plates are subsequently rotated around the normals of the plates by an equal twist angle but in opposite directions. When a beam of light is passed through the assembly post-twist, the result is high-quality fringes that are straight, smooth and capable of exhibiting close to 100% contrast. The fringes have a sinusoidal cross-fringe profile and vary in number in relation to the degree of the twist angle.Type: GrantFiled: March 13, 2001Date of Patent: February 19, 2002Assignee: The United States of America as represented by the Secretary of the ArmyInventor: John L.

Patent number: 6275327Abstract: The all-optical pulse generating and amplifying system utilizes a phosphor that is excited by input light of a first wavelength and, in response, emits light of a second wavelength. The light emitted by the phosphor illuminates a bistable element which, at a pre-fixed intensity of the phosphor-emitted light, switches from non-transmissive state to transmissive state, thereby allowing the exit of light (also of first wavelength) emitted by an output light source as light pulse output of the system. An inhibitory light that also passes through the bistable element during its transmissive state quenches the phosphor light emission and returns the bistable element to its non-transmissive state and re-starts the process toward the next transmissive state. By gating the intensity, via selected non-linearity of the bistable element, of the light output in proportion to the intensity of the input light, the system can also function as an amplifier.Type: GrantFiled: March 22, 1999Date of Patent: August 14, 2001Assignee: The United States of America as represented by the Secretary of the ArmyInventors: John L. Johnson, William A. Friday, Gary L. Wood

Patent number: 6181303Abstract: Two liquid crystal display panels, stacked together into a flat compact unit, in conjunction with a dedicated processor producing the appropriate video signals to drive the panels, generates a pair of polarization-encoded left and right images and exhibits them as a stereo image that is viewable through a pair of standard polarized glasses. This makes it possible to obtain stereo effect at a video workstation or at a console by eliminating the bulky box-like setup or the need to project onto a screen.Type: GrantFiled: October 5, 1998Date of Patent: January 30, 2001Assignee: The United States of America as represented by the Secretary of the ArmyInventors: John L.
