Abstract: Parasitic reactions, such as production of hydrogen and oxidation by oxygen, can occur under the operating conditions of flow batteries and other electrochemical systems. Such parasitic reactions can undesirably impact operating performance by altering the pH and/or state of charge of one or both electrolyte solutions in a flow battery. Electrochemical balancing cells can allow rebalancing of electrolyte solutions to take place. Electrochemical balancing cells suitable for placement in fluid communication with both electrolyte solutions of a flow battery can include: a first chamber containing a first electrode, a second chamber containing a second electrode, a third chamber disposed between the first chamber and the second chamber, an ion-selective membrane forming a first interface between the first chamber and the third chamber, and a bipolar membrane forming a second interface between the second chamber and the third chamber.

Abstract: The present document describes an apparatus and method for monitoring and interacting with listeners of audio-video content. There are provided audio signals from which audio-video content can be identified by a monitoring peripheral paired with a user's electronic device. The monitoring peripheral monitors audio signals from its surroundings and communicates to the paired user's electronic device, decoded and/or generated digital IDs from these audio signals. A master service application or registered service application running on the electronic device could transmit the digital ID to a remote server and retrieve additional information from these digital IDs with or without the use of a backend system. Events could be triggered and relevant audio- video content be presented to the user of the master service application or a registered service provider when digital IDs are received from the monitoring peripheral.

Abstract: A method and apparatus for preventing a GFCI device from being miswired is provided where the GFCI device is enabled to enter a latched state only after the GFCI device is correctly wired to a power supply. An exemplary GFCI device includes a latch assembly provided with a rigid electrically conducting bar connected thereto such that when a user presses a reset button provided on the GFCI device, the latch assembly is moved toward a pair of contacts provided as part of a reset circuit to initiate a reset operation. When the electrically conducting bar on the latch assembly connects the pair of contacts, the reset circuit is closed and an actuator is activated to place the GFCI device in the latched, reset, condition. If the GFCI device is correctly wired, the closed reset circuit will cause a firing member to move from a first position to a second position enabling the latch assembly to enter the latched state. The exemplary latch assembly is connected to a resilient biasing member that biases the latch assembly and the shorting bar away from contacting the pair of contacts except when urged against the force of the resilient biasing member by a user of the GFCI device. Further, because the GFCI device is delivered in the tripped, unlatched state, and cannot be latched, or placed in the reset condition, until it is properly wired, the miswiring prevention functionality is immune to vibrations or shock prior to the device being installed. According to further embodiments a automatic self-test circuit is provided for periodically testing the fault detection ability of the device without human intervention.
