Abstract: A process for determining a content of hydrogen in a fluid medium includes contacting the fluid medium with a sensor. The sensor has a housing enclosing a chamber containing an ionic liquid electrolyte, a window which is permeable to hydrogen and positioned in an opening in the housing, and electrodes in contact with the ionic liquid electrolyte in the chamber. Hydrogen is allowed to pass through the window from the fluid medium into the electrolyte and the sensor is heated. Temperature and pressure of the fluid medium is determined and electrical potential is applied to the electrodes. The method also includes measuring current flow. The sensor can be used to observe hydrogen concentration by voltammetry. The method and sensor may be used for measuring downhole hydrogen content, monitoring fiber-optic cables for damage by hydrogen, corrosion monitoring, and in small-scale process plants where hydrogen is part of a gas stream.

Abstract: According to one configuration, a wireless station monitors for presence of wireless communications transmitted in a subscriber domain (monitored region) to identify which of one or more communication devices assigned to the subscriber domain are present in the monitored region. In response to detecting presence of a particular communication device, a mapping resource maps an identity of the communication device and/or corresponding user of communication device to configuration settings (such as a personalized content guide) assigned to the corresponding user of the communication device. The playback device displays the personalized content guide and corresponding control options on a display screen of the playback device to the user. The user then operates a remote control device (which is separate from the communication device) to control selection of options in the displayed personalized content guide of the user.

Abstract: Embodiments provide WiFi and LTE tailored transceiver radio frequency (RF) filtering techniques and configurations to enable coexistence between WiFi and LTE transceivers operating in close proximity. In particular, embodiments provide filtering techniques to reject emissions from LTE into WiFi, and vice versa. The filtering techniques eliminate the need for additional isolation between LTE and WiFi antennas (approximately 50 dB), which is beyond what is achievable in practice. Embodiments can be tailored according to different use cases of the WiFi and LTE transceivers (e.g., fixed CPE, portable router, smart phone with tethering).
