Abstract: A shape memory alloy composite fabric and a method of use is provided in underwater pressure vessels and as flexible joints in atmospheric diving suits. The atmospheric diving suit internal pressure is one atmosphere for underwater transit to and from an underwater work site. During operations at a work site, the shape memory alloy joints transform to a martensite phase and enable greater flexibility while the pressure in the atmospheric diving suit equalizes with ambient depth pressure.

A method for extracting features for natural language processing comprises: accessing one or more tokens generated from a document to be processed; receiving one or more feature types defined by user; receiving selection of one or more feature types from a plurality of system-defined and user-defined feature types, wherein each feature type comprises one or more rules for generating features; receiving one or more parameters for the selected feature types, wherein the one or more rules for generating features are defined at least in part by the parameters; generating features associated with the document to be processed based on the selected feature types and the received parameters; and outputting the generated features in a format common among all feature types.

Abstract: A towel cooler assembly includes a container body with removable lid that is configured to seal an interior volume. Within the volume is stored a cooling medium and a fabric divided by a removable divider. The assembly is configured to internally house an absorbent fabric and locate such fabric adjacent to a cooling medium such as water in a liquid or solid state. The assembly is configured to include a divider which selectively allows passage between the cooling medium and the fabric. The fabric remains at a cool temperature similar to the cooling medium.

Abstract: Multi-radio wireless network devices are capable of transmitting and/or receiving data from multiple radiofrequency (RF) networks at different bands. Total transmission power limitations may be in place due to, for example, safety reasons. As a result, active management of transmission power may be performed during simultaneous transmission in different bands and/or networks. In some embodiments, the management may take place on group-by-group basis and a network-by-network basis. Antennas may be grouped based on their relative positions and impact on radiation emitted by the devices.

Abstract: A series of a plurality of articles includes a panel strip and a plurality of elastic fastening loops. The panel strip includes a plurality of ruptureably-connected panel portions of the plurality of articles. Each of the plurality of elastic fastening loops is secured to a respective panel portion at a bond zone.

Abstract: Providing a facilities supervisor notice after a conference room or other common area has been used and is in a messy condition. An image of the conference room obtained after use is evaluated to determine if the conference room is neat. A neatness score is obtained for the conference room. If the score indicates a neatness value above a settable level, the conference room is considered clean and ready for use. If the neatness score indicates a neatness value less than the settable level, the conference room is not ready for use, and a notice is provided to the facilities supervisor to allow a cleaning person to be dispatched. The need to perform the cleanliness or neatness review is triggered by referencing scheduled meetings in a calendaring system, by monitoring the conference room for the presence of individuals having an unscheduled meeting and periodically or randomly.

Abstract: Inserts disposed in a housing of a pneumatically or hydraulically powered tool having a motor adapted to rotate a drive lug in either of first and second rotational directions. The insert is composed of a material resistive to creep and/or stress relaxation. The insert contacts fasteners applying a clamping force to the tool and remove the housing from the load path of the clamping force, thereby reducing the possibility of fluid leaks.

Abstract: Aspects of the present disclosure involve a power supply circuit for powering a plasma reactor and more specifically initiating and maintain a plasma therein, and that can operate with power from an intermittent power source. The power supply may include an auxiliary-power supply or trigger circuit, in addition to a primary-power supply circuit, which can reduce the need for high-voltage equipment in the high-power section of the power supply. In one particular use, the power supply includes a high-voltage power output that may be used for generating a plasma between electrodes, for example, in a nitrogen-fixation plasma system. The power supply circuit may provide the flexibility to power a plasma reactor using an intermittent power source, such as solar, wind, and/or a periodic low-cost power grid, while reducing wasteful power conditioning, lowering the cost of operation, and increasing the efficiency of chemical production from the renewable energy.

Abstract: The present invention comprises novel methods of continuously monitoring the performance of an atmospheric pressure ionization (API) system. The methods of the invention allow for improved quality monitoring of the processes that leads to the formation of ions at atmospheric pressure. The methods of the invention further allow for continuously monitoring for the quality of the ion formation process in API without the addition of extraneous material (such as labelled compounds or control known compounds) to the system being monitored.

Abstract: A marine drive is for propelling a vessel in body of water. The marine drive has a powerhead, a crankcase on the powerhead, and a cooling system that pumps a first flow of cooling water from the body of water through a powerhead cooling conduit for cooling the powerhead and in parallel pumps a second flow of cooling water from the body of water through a crankcase cooler for cooling the crankcase and lubricant in the crankcase. A valve controls the second flow of the cooling water to the crankcase cooler. The valve is normally positioned in a closed position, which inhibits the second flow of cooling water to the crankcase cooler and thereby reduces condensation of water from the lubricant in the crankcase. The valve is moved into an open position upon operation of the powerhead at or above a threshold speed, which permits the second flow of cooling water to the crankcase cooler and thereby cools the lubricant in the crankcase.
