Abstract: The present application discloses electronic plumbing fixture fittings, such as electronic faucets, with a shaped and limited sensor detection zone. Exemplary embodiments include devices with a plurality of overlapping sensors and devices with a single time-of-flight (TOF) sensor capable of detecting the presence or absence of an object whether or not water is flowing out of a discharge outlet in the in a TOF detection zone.
Abstract: A water quality measurement apparatus is provided. The apparatus comprises an electrochemical cell, a pH sensor, a temperature sensor, a control circuit, a power source, a database, and a warning device. The electrochemical cell comprises a working electrode, a reference electrode, and a counter electrode. The control circuit provides predetermined adjustable potentials between the reference electrode and the working electrode and measures electrochemical currents between the working electrode and the counter electrode, to form a current diagram based on the predetermined adjustable potentials and the electrochemical currents. The database stores predetermined reference diagrams based on various pH values and temperatures, and is in communication with the control circuit.

Abstract: The present invention provides an electronic plumbing fixture fitting with an electronic valve including a piston and a seat, such as an electronic faucet with an electronic valve including a piston and a seat.
Abstract: The present invention provides a plumbing fixture fitting having a spray mode with improved spray performance. The fitting includes a spray face. The spray face includes nozzles. The nozzles are operable to deliver water from the spray face in the form of a spray. The spray includes streamlets. An average unbroken length of the streamlets is greater than approximately two inches at a flow rate of approximately thirty-seven thousandths gallons per minute.
Abstract: A magnetic shower curtain system that maintains a shower curtain in place along opposing shower enclosure walls. The magnetic shower curtain system includes a shower rod assembly, a mounting assembly, and a shower curtain assembly. The shower curtain assembly includes a plurality of shower rings. The shower rings are placed on a shower rod, connected to a shower curtain, and slid along the shower rod. The shower rings include a first outer shower ring and a second outer shower ring. One of: (1) the first outer shower ring and the second outer shower ring, and (2) a first outer end and a second outer end of the shower rod or the mounting assembly, includes a magnet. The other of: (1) the first outer shower ring and the second outer shower ring, and (2) the first outer end and the second outer end of the shower rod or the mounting assembly, includes a magnet or a magnetically attractable material.
Abstract: The present invention provides a mounting system for an accessory that enables a consumer to easily install and uninstall the accessory on a mounting surface. The accessory mounting system includes a post and a mounting assembly. The mounting assembly includes a first mounting subassembly and a second mounting subassembly. The first mounting subassembly includes a deflectable member. The second mounting subassembly includes a set screw. The post is operable to be attached to the mounting surface by an engagement of the first mounting subassembly with the post and a snap engagement of the deflectable member of the first mounting subassembly with the second mounting subassembly. The post is operable to be removed from the mounting surface by unthreading the set screw and disengagement of the deflectable member of the first mounting subassembly with the second mounting subassembly and disengagement of the first mounting subassembly with the post.
Abstract: The present invention provides an electronic plumbing fixture fitting with an electronic valve having a low seal force, such as an electronic faucet with an electronic valve having a low seal force.
