  • Publication number: 20210092148
    Abstract: A method of relay-attack resistant communications in a wireless communications system that includes a master wireless device (Master) sending a synchronization signal to a slave wireless device (Slave). The synchronization signal includes timing information including a common time reference and a timeslot duration for interlocking Master communication timeslots for Master and Slave communication timeslots so that an alternating TX and RX role pattern is provided. The Master analyzes Slave packet data received from the Slave to identify overlaps of a transmission from the Master and the slave packet data, and in a case of detecting overlap, suspends communications from Master to Slave to prevent a relay-attack.

  • Patent number: 10704244
    Abstract: A fill valve with pressure chamber having an open bottom end and a diaphragm at a top end such that falling water level in the toilet tank causes the diaphragm to flex in a first direction, thereby moving a sealing member to an open position, with a venturi in the fill valve keeping the sealing member in the open position until water refilling the tank causes the diaphragm to flex in a second direction, thereby moving the sealing member back to the closed position.

  • Publication number: 20200141103
    Abstract: Methods and systems described herein are direct to an external lever configured to be positioned external to a toilet tank and actuated by a user to cause a toilet tank to flush. A first component comprising a first longitudinal member may couple to the external lever. A second component comprising a second longitudinal member may engage the first component at a perpendicular angle with respect to the first longitudinal member. The first and second components make up an arm that is configured to pass through a wall of the toilet tank. An internal lever arm may be positioned within the toilet tank such that the internal lever couples to the second component.

  • Patent number: 10577786
    Abstract: Some embodiments include a fluid control assembly with a flapper canister, a linkage rotatably coupled to the flapper canister and to a support of a mount. In some embodiments, the flapper canister can be angled with respect to the mount to enable the flapper canister to be coupled to various sizes, types and orientations of flush valves. In some embodiments, by rotating the linkage about pivots coupled to the flapper canister and the support and pivoting or rotating about a motion-enabling element coupling the mount and a support, the flapper canister can be raised, lowered, and/or rotated or pivoted enabling the flapper canister to be sealed against a flush valve orifice. In some embodiments, the flapper canister includes a buoyancy control tube providing fluid coupling between one side of the flapper canister to an opposite side and enabling buoyancy-assist to the position or motion of the flapper canister.

  • Patent number: 10352030
    Abstract: A toilet having a tank to receive water and a bowl connected with the tank. Water travels from the tank to the bowl to discharge waste in the bowl through a manifold connected to the bowl and into a drain line. The toilet has a jet trapway portion having a jet inlet with a nozzle connected with the tank. The nozzle directs water from the jet inlet to overcome an upward bend in the jet trapway portion until received by the manifold at an inlet below the upward bend. A waste trapway portion extends from the manifold opposite the jet trapway portion and connects with the drain line. Waste is discharged from the bowl through the manifold over a bend in the waste trapway portion by combining water flowing from the jet trapway portion into the manifold with waste flowing from the manifold into the waste trapway portion.
