摘要:
An organohydrosiloxane composition comprising: a) one or more organohydrosiloxane compounds, each having at least one [—HSiR-O—] unit, wherein R═C1-C18 linear, branched, or cyclic alkyl, C1-C18 linear, branched, or cyclic alkoxy, or substituted or unsubstituted aryl, and b) an antioxidant compound shown in Formula (1) wherein the antioxidant compound is a phenolic compound and is present in a concentration from about 1 ppm to about 5,000 ppm and wherein R1 through R5 can each independently be H, OH, C1-C18 linear, branched, or cyclic alkyl, C1-C18 linear, branched, or cyclic alkoxy or substituted or unsubstituted aryl. The compositions of present invention exhibit stability and significantly extend the shelf life of organohydrosiloxane products and allow greater flexibility in handling these products in chemical processes or semiconductor manufacturing. The resulting stabilization of siloxanes prevents the possibility of complete polymerization (i.e., solidification) of product in chemical delivery lines or valves, which lowers equipment maintenance and costs and reduces time the machinery is out of production.

A process for measuring the location of people and objects carrying radio frequency (RF) transmitters (TXs) that transmit messages to a plurality of RF receivers (RXs) located in a space. Each RX is in communication with a computer of a computer network and forwards data received from the TXs to the network via its associated computer, along with a value indicating the signal strength of the received TX transmission. The signal strengths attributable to the same transmission are used to form a locating signal strength vector which is then compared to exemplary vectors generated from signal strength readings gathered in a calibration procedure from a set of representative locations in the space. In comparing the locating vector to the exemplary vectors, constraints are enforced on movements between locations (e.g., cannot pass through walls) and to probabilistically enforce expectations on transitions between locations.

An edge adaptive system and method for image filtering. The method maps each output pixel onto input image coordinates and then prefilters and resamples the input image pixels around this point to reduce noise and adjust the scale corresponding to a particular operation. Then the edge in the input image is detected based on local and average signal variances in the input pixels. According to the edge detection parameters, including orientation, anisotropy and variance strength, the method determines a footprint and frequency response for the interpolation of the output pixel. In a more particular implementation, the method divides the input pixel space into a finite number of directions called skews, and estimates the edge orientation with the nearest skew direction. This further facilitates pixels inclusion in the interpolation of the output pixel.

An apparatus and method of controlling the delivery of therapeutic gas delivered to a patient undergoing positive airway pressure therapy is described. The method includes providing a flow of gas to a patient's airway at a pressure, obtaining information from the range of 0 to 25 Hz of the frequency domain of the flow, and adjusting the pressure based on the information. The apparatus includes a blower for providing a flow of gas to a patient's airway at a pressure, a sensor to measure a characteristic of the flow, a controller to obtain information from the range of 0 to 25 Hz of the frequency domain of the characteristic, and a pressure regulator for adjusting the pressure based on the information.

A method for providing a collaborative, shared workspace is provided. The method includes receiving an identity of at least one of a plurality of participants. At least one resource to share information between the plurality of participants is determined. A community comprising the identity of the at least one of a plurality of participants and the at least one resource is established. The community can enable the plurality of participants to share information in collaboration using the at least one resource.

The present invention is a device that provides a trouble free method to invert glove appendages expeditiously; especially but not exclusively, industrial, heavy duty, lined, rubber gloves; to facilitate efficient cleaning and subsequent rapid drying of the lining, which consists of a base that has a cavity and a pushrod that fits into the cavity in the base to be securely mounted therein, wherein the exposed cavity in the tip of the pushrod engages the tip of the glove appendage insuring continuous contact between the tip of the pushrod and the glove appendage tip while the glove is peeled down over the pushrod, thereby accomplishing complete inversion of the glove appendage.

An oil separator for use in a vehicle air system includes a recycling valve for removing coalesced oil. The recycling valve may include a piston movable in a cylinder in response to a control air pressure to open the recycling valve and thus drain coalesced oil from a sump under the influence of residual air pressure in the sump. The separator may include a fixture for mounting the separator to a vehicle, including a plurality of ports extending from an inlet port for directing air into the cartridge with a combined flow area at least equal to the flow area of the inlet port. The plurality of ports preferably extend at a right angle to the direction of flow of air through the inlet port. A safety relief valve on the separator releases air when the pressure exceeds a predetermined pressure.
