Abstract: Four main sets of features designed to improve the apartment rental and listing process are discussed: (i) improved visualization of listings for renters using clustering, especially for mobile; (ii) landlord transaction flow and support; (iii) cross-checking of data using user-initiated third-party web data; and (iv) maintenance flow and support. The clustering approach provides visualization of dynamically developed clusters from available listings; rapid (re-)computation of clusters as the map is adjusted by users; and representation of all matching listings in the region in a cluster or as a single entry cluster at all times.

Abstract: Disclosed herein is an apparatus for on-line detection of leaky valve seals wherein the apparatus includes an isolation valve having at least one upstream seal, at least one downstream seal, a fluid flow diverter; an inner cavity isolated from a fluid flow path by the seals; a vent port disposed in fluid communication with the inner cavity; a vent valve disposed in fluid communication with the vent port; and a differential pressure sensor disposed in fluid communication with both the vent port and the fluid flow path.

Abstract: A variable function voting solenoid-operated valve apparatus is provided having both high safety availability and high plant reliability that does not require a plant system to be bypassed during testing. Also provided is a variable function voting solenoid-operated valve apparatus wherein initiation of a safety action will occur only if each of a pair of operatively associated solenoid-operated valves in the apparatus are actuated, and wherein either of the solenoid valves can singly default to a pre-designated safety action without inadvertently actuating the process valve and isolating or venting the process fluid.
