Title: Composite cushion with compression modulated valve and valve assembly there for
Inventor: HITCH PHILIP R
IPC: F16K15/14
Filed: 2007-09-18
Abstract: Valve assemblies optionally with inflatable bodies for modulating fluid expulsion from an inflatable body, without active user participation. Valve assemblies include, in separate components or in integrated form, a vent body defining an external orifice, an internal orifice in fluid communication with the external orifice, and an inflatable body interface. Extending from the internal orifice is a collapsible, hollow elongate member defining longitudinal and lateral axes. Sealing closure of the elongate member, which is preferably constructed from a resilient material, results from application of generally opposing mechanical forces across a lateral surface of the elongate member. Compression localizing members may be used proximate to the elongate member to increase closure performance. In addition, performance parameters can be varied by modifying the physical characteristics of the compression members (height, upper surface area, lower surface area, composition, density, use of localizing ridges, etc.) as well as locations of the compression members (proximity to other compression members, distribution relative to the cushion geometry, etc.).

Abstract: The novel positively charged pro-drugs of lH-imidazo[4, 5-c]quinolin-4-amines and related compounds in the general formula (1) 'Structure 1' or formula (2 ) 'Structure 2 ' were designed and synthesized. The compounds of the general formula (1) 'Structure 1' or formula (2) 'Structure 2' indicated above can be prepared from lH-imidazo[4, 5-c]quinolin-4-amines and related compounds, by reaction with suitable acetic anhydride or acetic chloride. The positively charged amino groups of these pro-drugs not only largely increases the solubility of the drugs in water, but also bonds to the negative charge on the phosphate head group of membranes. This bonding will disturb the membrane a little bit and may make some room for the lipophilic portion of the prodrug. When the molecules of membrane move, the membrane may 'crack' a little bit due to the bonding of the prodrug. This will let the prodrug insert into the membrane. At pH 7.4, only about 99% of the amino group is protonated. When the amino group is not protonated, the bonding between the amino group of the prodrug and the phosphate head group of the membrane will disassociate, and the prodrug will enter the membrane completely. When the amino group of the prodrug flips to the other side of the membrane and thus becomes protonated, then the prodrug is pulled into the cytosol, a semi-liquid concentrated aqueous solution or suspension. The results suggest that the pro-drugs diffuse through human skin -25 times faster than do lH-imidazo[4, 5-c]quinolin-4-amines and related compounds. In plasma, more than 90% of these pro-drugs can change back to the parent drugs in a few minutes. The prodrugs can be used medicinally in treating any lH-imidazo[4,5-c]quinolin-4-amines and related compounds-treatable conditions in humans or animals. The prodrugs can be administered transdermally for any kind of medical treatments and avoid most of the side effects of 1H-imidazo[4, 5-c] quinolin-4-amines and related compounds. Controlled transdermal administration systems of the prodrug enables lH-imidazo[4, 5-c]quinolin-4-amines and related compounds to reach constantly optimal therapeutic blood levels to increase effectiveness and reduce the side effects of lH-imidazo[4, 5-c]quinolin-4-amines and related compounds.

Title: Thermally switched reflective optical shutter
Inventor: POWERS RICHARD M
IPC: G02B26/02
Filed: 2008-07-11
Abstract: The thermally switched reflective optical shutter is a self-regulating "switchable mirror" device that reflects up to 100% of incident radiant energy above a threshold temperature, and reflects up to 50% of incident radiant energy below a threshold temperature. Control over the flow of radiant energy occurs independently of the thermal conductivity or insulating value of the de-vice, and may or may not preserve the image and color properties of incoming visible light. The device can be used as a construction material to efficiently regulate the internal temperature and illumination of buildings, vehicles, and other structures without the need for an external power supply or operator signals. The device has unique aesthetic optical properties that are not found in traditional windows, skylights, stained glass, light fixtures, glass blocks, bricks, or walls. The device can be tailored to transmit sufficient visible light to see through in both the transparent and reflective states, while still providing significant control over the total energy transmission across the device.

As a user touches the touchscreen at a first location, a cursor may be displayed at that location. Because the cursor, as well as various items displayed on the touchscreen, are likely now obscured by the instrument used to touch the touchscreen, the user may sweep his or her finger away from the first location, at which point a pointer, or similar connection element, may be displayed between the cursor, which is maintained at the first location, and the second, new location of the instrument. The user may unlock the connection element and cursor, causing the connection element, and by extension the cursor, to begin moving with the instrument. The user may then move the cursor to its desired location by movement of the offset connection element.
