Assignee:

Graco Minnesota Inc. - Minneapolis MN

International Classification:

B67B 1/00

US Classification:

222 20, 137215, 13762533, 222 22, 222 72, 222 74, 22215314

Abstract:

A valve comprises a valve cartridge, a valve stem and a valve seal. The valve cartridge comprises a generally cylindrical cartridge body, a bore extending longitudinally through the cartridge body, and an outlet passage and intermittent inlet passages extending through a side wall of the cartridge body to intersect the bore. The valve stem comprises an elongate body configured to slide within the bore, and a neck and a seal channel circumscribing the elongate body. The valve seal is seated within the seal channel. The valve stem slides within the bore to move the seal channel past the inlet passages. Portions of the cartridge body between the inlet passages retain the valve seal within the valve channel until the inlet passages are open to the neck. In one embodiment, the inlet passages form a crenelated edge. In another embodiment, the inlet passages form a ported end.

International Classification:

B32B 3/02

US Classification:

428064100

Abstract:

The invention is directed toward techniques for shielding a reflector of a data storage medium from ultra-violet (UV) and solar radiation. Reflectors comprise materials, such as silver, that may degrade and lose their reflective properties when exposed to UV light. In some cases, exposing the reflector to UV light may degrade a recording layer positioned adjacent the reflector in a recordable data storage medium. Degradation of the reflector and/or the recording layer can lead to significant data losses in the data storage medium. The techniques described herein position a blocking material adjacent the reflector in order to protect the reflector and data stored on the data storage medium from exposure to UV light. The blocking material may comprise UV absorbing properties in order to substantially eliminate transmission of UV light through the backside of a data storage medium.

Appl. No.:

11/418584

Inventors:

Daniel Rogers - Grant MN, US
Jathan Edwards - Afton MN, US

International Classification:

G11B 7/00

US Classification:

369112010, 369094000

Abstract:

Techniques are described for simultaneously accessing multiple layers of an optical data storage medium using optical elements. The techniques include passing light through one or more optical elements included in an optical device to generate multiple light beams with focus points on two or more layers of a multi-layer optical disk. In some cases, the optical device may include a single optical element that generates multiple light beams. In other cases, the optical device may include two or more optical elements that each generates a single light beam. In either case, the optical device may simultaneously access two or more of the layers of the optical disk. An optical element may comprise a diffractive optical element or a holographic optical element designed to accommodate the separation distance between each of the layers of a multi-layer optical disk and a power ratio for the layers of the multi-layer optical disk.

Daniel J. Rogers - Grant MN, US

International Classification:

A61B 7/04

US Classification:

600586, 381 67

Abstract:

An electronic stethoscope includes a housing configured for hand-held manipulation, a transducer supported by the housing and configured to sense auscultation signals at a first location, and a headset coupled to the housing and configured to deliver audio corresponding to the auscultation signals through earpieces on the headset. The electronic stethoscope further includes a processor disposed in the housing and configured to convert the auscultation signals to first digital signals representative of the auscultation signals and to wirelessly transmit the first digital signals from the electronic stethoscope via a secure digital network to a second location such that the audio corresponding to the auscultation signals is provided to headsets of one or more additional electronic stethoscopes at the second location in substantial real time with the sensing of the auscultation sounds at the first location.

Inventors:

Lynn Galarneau - Golden Valley MN
Daniel J. Rogers - White Bear Lake MN

Assignee:

Honeywell Inc. - Minneapolis MN

International Classification:

B32B 3100

US Classification:

1563798

Abstract:

An apparatus for replicating diffractive optical elements by embossing a master optical element into a photopolymer material disposed on a substrate, including a fixture for retaining, aligning, and conveying radiation to the embossing sample so that the photopolymer cures under pressure. Intermediate nickel optical elements may be used in lieu of quartz optical masters. The liquid processing techniques disclosed herein allow the replication of diffractive optics on curved substrates. This additional advantage eliminates the need for a plano optical interface further reducing the element count for a given optical system.

International Classification:

US Classification:

427162

Abstract:

The present invention discloses 1) a process for photopolymer replication on plastics, and 2) the scale-up step-and-repeat process in photopolymers. High fidelity optical element replication using a master optical element having submicron diffractive pattern feature sizes embossed into a UV curable photopolymer material for step-and-repeat "tiling" replication of the master optical element to create light weight, low cost, large area diffractive optical elements (LADOE). Furthermore, by using a chrome mask to eliminate ridge formation around a single diffractive optic element extremely narrow seams result, thereby increasing the optical fidelity of the resulting LADOE. Accordingly, each LADOE made according to the present invention is characterized by having minimum seam widths between patterns of discrete diffractive optic elements that introduce negligible optical distortion to a viewer.

Abstract:

Aspects of the present disclosure relate to an ergonomic chestpiece for a stethoscope. The chestpiece includes a bottom surface which is generally planar and adapted to be placed near the patient for receiving auscultatory sounds. The chestpiece includes a raised center portion defining first and second lateral indented gripping surfaces, the raised center portion having a top surface opposite the bottom surface. The chestpiece includes a stem portion extending distally from the raised center portion. The first lateral indented gripping surface is defined by a first wall comprising a first concave surface arcuate about a first axis and the second lateral indented gripping surface is defined by a second wall comprising a second concave surface arcuate about a second axis. The first axis and the second axis form a V-shape comprising an apex oriented in a direction of the stem portion.
