Abstract: Selective and protected release of private information/data to an incident response team (for example, public safety personnel) is disclosed. The private data (which pertains to individuals recorded as being within a premises at the time of an incident with respect to which the incident response team is responding to) may take the form of a system-generated log, which may be transferred to a first level of the public safety personnel once authenticated. Based on at least one of role, incident type, and incident severity, the first level of authenticated public safety personnel may release at least a portion of the private data to a second level of authenticated public safety personnel.

Abstract: Disclosed is an integrally combined electrical current carrier, circulation chamber and frame (CCF) formed as a single or double part (CCF) for use in unipolar electrochemical devices. The CCF is structured to define an internal circulation chamber for circulation of electrolyte, products, and reactants as well as apertures which form flow passageways when the filter press device is assembled. Affixed on opposed surfaces of the CCFs are electrically conductive planar electroactive structures which are in electrical contact with the CCF. The circulation chamber is formed by the depth of the CCF itself between opposing electroactive structures. Multiple CCFs are assembled and compressed together to form the filter press electrolyser apparatus. When power is applied to the CCFs and electroactive structures, the reactants, once they flow into the circulation chamber with the electrolyte, undergo redox reactions to produce products that are collected and exit the electrolyser in upper flow pathways.

Abstract: The present disclosure pertains to detection of abnormal, risky, or abberant conditions in a power distribution network and to corresponding trip signals being used to trip open devices such as reclosers upstream of where the abnormal condition is detected. Detection of a missing broadband over power-line signal or of an open circuit between phases of a power distribution circuit may prevent severed conductors from causing a ground fault, therefore avoiding the possibility of fire and dangerous conditions.

Abstract: Disclosed is an end assembly for use in a unipolar filter press electrolyser, where the unipolar filter press electrolyser has a filter press stack. The end assembly of the unipolar filter press electrolyser includes an end plate component having two apertures, the two apertures being alignable with channels formed in the filter press stack. The two apertures include a first aperture configured to receive a stream of liquid electrolyte and gases from the filter press stack, and a second aperture configured to receive a stream of recirculated liquid electrolyte. In addition, the end assembly includes an end clamp configured to apply a clamping force on the end plate component to securely retain the filter press stack. The end clamp includes one gas offtake port to extract gases from the stream of liquid electrolyte and gases from the first aperture and discharge the gases out of the unipolar filter press electrolyser.
