  • Publication number: 20220034076
    Abstract: A ventilated toilet for removing odors from the toilet base includes a unitary molded tank assembly with an integral ventilation cavity formed along the base and the back inside of the water tank. At least one water channel connects a water inlet chamber of the base to the water tank and is configured to channel water into the base when released from the tank, as well as to provide an airflow conduit for odors present in the base to be removed from the base via the ventilation cavity. A flush valve extends through the ventilation cavity to connect the tank and the base, and is sealed in attachment to eliminate egress of odors. The system permits substantial elimination of odors at flush volumes of 1.6, 1.3 or 0.8 gallons per flush by virtue of the enhanced seals and unitary construction. A toilet tank assembly in accordance with the invention is also disclosed.

  • Patent number: 11149425
    Abstract: Please amend the abstract as follows: This invention relates to a ventilated toilet system for removing obnoxious odors from the toilet base and includes integral vent channels formed along the base and the back inside of the water tank, and a vent adapter mounted inside the passage that directs the flow of ventilating air along the vent channels to an exhaust pipe and discharges it by a remote in-line exhaust fan to the outside atmosphere. The adapter is attached to the base of the overflow flush valve pipe or, conversely, designed to be an integral part of the overflow flush value pipe, itself, and is positioned to connect the base vent channel of the water tank to the toilet water inlet chamber of the base for passage of ventilating air, and to connect the overflow flush valve pipe to the water inlet chamber for passage of flush water.

  • Publication number: 20210197763
    Abstract: Example user identification systems and methods are described. In one implementation, a method determines a first step pulse associated with a user carrying a key fob and detects a user device proximate the key fob. The method further identifies a second step pulse measured by the user device and determines whether the first and second step pulses match. If the step pulses match, the user carrying the key fob is identified as the owner of the user device.
