Abstract:
A method is disclosed that includes allowing both frequency and amplitude of a periodic waveform to be adjusted. The method also includes creating the periodic waveform having the frequency and the amplitude. The periodic waveform is coupled to at least one control signal. The at least one control signal is provided to an output suitable for coupling to an actuator of an electronically controlled device. An apparatus and computer program product are disclosed.
Abstract:
Image editing tools are commonly used to assist with manipulating and saving visual compositions. Many image editing tools provide slicing functionality to create images slices (sub-images) of the visual composition. As provided herein, a slice representation of a visual composition is defined by an arbitrarily chosen set of coordinates within the visual composition. This slice region may be defined independent of other slice regions (e.g. the slice region may or may not overlap, abut, etc. other slice regions). The slice representation comprises the slice region and one or more objects or portions thereof within the slice region. Slice representations may also comprise overlapping objects and/or slice region coordinates. Objects may be manipulated within a slice representation without affecting that object within other slice representations.
Abstract:
An artificial inflatable airway device is described that includes at least one inflatable sealing portion and a pressure monitoring means, the sealing portion and the pressuring monitoring means being integrally and operably attached, adapted to measure at least one pressure within the sealing portion of the inflatable airway.
Abstract:
A method of making a laryngeal airway of the type that includes a respiratory tube and an inflatable positioning shield having a base and an inflatable, hollow peripheral portion is described herein. The method includes introducing at least one molding material onto internal walls of a mold, wherein the mold has a cavity defined by internal walls that conform to the external wall of the laryngeal airway, and wherein only a sufficient amount of the molding material is introduced onto the internal walls of the mold that is necessary to create external walls of the laryngeal airway having a desired thickness and allowing the molding material to cure about the internal walls, thereby forming laryngeal mask.
Abstract:
Polymeric reagents comprising a polymer attached, either directly or through one or more atoms to a ketone or a related functional group such as ketone hydrate, thione, monothiohydrate, dithiohydrate, hemiketal, monothiohemiketal, dithiohemiketal, ketal, or dithioketal are provided. The polymeric reagents are useful for, among other things, forming polymer-active agent conjugates. Related methods, compositions, preparations, and so forth are also provided.
Abstract:
A method of making a laryngeal airway of the type that includes a respiratory tube and an inflatable positioning shield having a base and an inflatable, hollow peripheral portion is described herein. The method includes introducing at least one molding material into a mold, wherein the mold has a cavity defined by internal walls, wherein the internal walls conform to external walls of the laryngeal mask, and wherein the mold has a core within its cavity that is adapted to form the hollow portions of the laryngeal airway.
Abstract:
Sorghum is considered an allelopathic crop species and sorgoleone likely accounts for much of its allelopathic properties. Prior investigations into the biosynthesis of sorgoleone suggested the participation of one or more alkylresorcinol synthases (ARS), which are type III polyketide synthases (PKS) that produce 5-alkylresorcinols using medium to long-chain fatty acyl-CoA starter units via iterative condensations with malonyl-CoA. Quantitative real-time RT-PCR analysis of PKS-like sequences mined from isolated root hairs revealed that two sequences, designated ARS1 and ARS2, were preferentially expressed. Recombinant enzyme studies demonstrated that both sequences encode ARS enzymes capable of accepting a variety of fatty acyl-CoA starter units. RNA interference (RNAi) experiments directed against ARS1 and ARS2 resulted in the generation of multiple independent transformant events exhibiting dramatically reduced sorgoleone levels. Thus, both ARS1 and ARS2 participate in the biosynthesis of sorgoleone in planta. ARS1 and ARS2 sequences were used to identify rice genes encoding alkylresorcinol synthases.

Abstract:
Methods and associated systems for improving the visual quality of real-time interactive multimedia presentations, by blending 2-D image data derived from a plurality of 3-D scene views associated with one or more 3-D scenes in accordance with presentation data modifiable by user input in real-time. The 2-D image data rendered from the perspective of the individual scene views are blended together using an associated blend mode in a back to front order producing a 2-D composite image for projection on a display device to a user of the real-time interactive multimedia presentation.
Abstract:
A positioning system includes an actuator, valve (preferably pneumatic), position sensor and an electronic valve controller, integrated in a single unit. Continuously variable setpoints are possible within the range of operation. A preferred control circuit includes a signal converter, a ramp generator to smooth the shape of the command or target value signal applied, a position feedback sensor to report the actual position of the actuator, a controller, and a driver, containing an H-bridge, for controlling the pneumatic valve which feeds air into the actuator mechanism. Integration of all these components into a single unit shortens signal paths, improves resistance to electrical noise, and permits faster response time.
