Abstract: A conical seal fitting (CSF) has a longitudinal bore between proximal and distal ends, an exterior conical sealing surface near the distal end and an exterior shoulder between the proximal end and the exterior conical sealing surface. A flange has a through-hole defined by an interior conical sealing surface and interior threads. A gland nut surrounds the CSF and has exterior threads that engage the interior threads. The gland nut presses against the exterior shoulder to push the two conical sealing surfaces together to form a seal. The CSF has an O-ring received in a groove and a trapped annular space is defined between the O-ring and the seal. The flange has a test port extending from outside of a vessel into the annular space. The annular space can be pressurized through the test port to test the seal. A tube passes through the bore and is sealed with the CSF using a ferrule and a nut.

Abstract: A system for extracting landfill gas from a landfill is provided. According to some embodiments, a control system for landfill gas extraction is provided. The control system uses a throttle to control flow of landfill gas extracted from the landfill. The throttle is actuated in use to vary the flow of gas between a well and a gas collection system, in accordance with a control algorithm that adjusts flow as a parameter in controlling gas extraction. The throttle is configured to ensure that there is at least some flow of landfill gas from the landfill to a gas output throughout operation. The extraction system provides an efficient system for landfill gas extraction, while mitigating a risk of creating undesired or unpleasant conditions and/or of violating regulations during operation.

Abstract: A system for remotely opening an access hatch of storage tank includes an elongate arm having a proximal end configured to be operatively coupled to a lid of the access hatch and a distal end extendable past an outer perimeter of the storage tank, and a pull cable attached to the arm at the distal end and being extendable toward a ground surrounding the storage tank. Pulling on the pull cable releases a latch that secures the lid to a base of the access hatch and allows the lid to pivot from a closed position to an open position.

Abstract: An example method is performed by a current defibrillator and includes determining that a memory embedded within a therapy cable coupled to the current defibrillator stores data indicative of a previous shock delivered to a patient, the previous being delivered using a previous defibrillator.

Abstract: Method and environment controller for inferring via a neural network one or more commands for controlling an appliance. A predictive model generated by a neural network training engine is stored by the environment controller. The environment controller determines at least one room characteristic.

The environment controller transmits the one or more commands to the controlled appliance.

Abstract: Top repairable gas-charged pulsation dampener designs include one or both of a threaded cover for bladder replacement and a standardized bladder with a double convex, anti-extrusion bladder button. The threaded cover, which speeds up bladder replacement over bolt-on covers, preferably has a two-piece construction to reduce torsion on the bladder neck. The bladder design, which includes a double convex, anti-extrusion bladder button, facilitates use of the same bladder design in both top repairable and bottom repairable gas-charged pulsation dampeners.

The infrared light source illuminates at least a portion of the stage with the structured infrared light. The controller also directs the scanner to scan the structured infrared light on the portion of the stage, receives signals from the scanner as scan data, and translates the scan data into three-dimensional location data.

Abstract: A CPR machine (100) is configured to perform, on a patient's (182) chest, compressions that alternate with releases. The CPR machine includes a compression mechanism (148), and a driver system (141) configured to drive the compression mechanism. A force sensing system (149) may sense a compression force, and the driving can be adjusted accordingly if there is a surprise. For instance, driving may have been automatic according to a motion-time profile, which is adjusted if the compression force is not as expected (850). An optional chest-lifting device (152) may lift the chest between the compressions, to assist actively the decompression of the chest. A lifting force may be sensed, and the motion-time profile can be adjusted if the compression force or the lifting force is not as expected.
