Abstract: Disclosed systems and methods include electronic devices attached to a patient or object that transmit data to other devices over a secure communication channel. The devices can track and/or monitor object(s) and/or patient(s) and transmit the tracked and/or monitored data to other electronic devices. Such data can include monitored patient physiological parameter(s) received and/or sensed by the device, for example. A master of the two devices transmits a communication signal to another device that, in response, initiates a secure wireless communication channel, causes one or more modules on the device to be powered, and, when powered, transmits the tracked and/or sensed physiological data over the secure wireless communication channel to the master device. Some example master devices transmit the communication signal with an instruction to the device to activate an onboard power source that later may be disconnected after the tracked and/or physiological data is transmitted.

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.
