Patent number: 11711745Abstract: In an adaptive route wireless network and bi-directional protocol, each computing device along a route to a gateway appends the previous node's network address to downstream messages as they are transmitted along the route from an originating computing device to the gateway. The list of appended network addresses thus records the route taken by the downstream network message through the adaptive route network. A server computing device maintains a route table including the list of appended network addresses received with each downstream message. To send unsolicited upstream messages to any computing device on the wireless network, the server generates an upstream network message that includes the appended network address(es) from the portion of the route table corresponding to the destination computing device. The upstream route to the destination computing device is thus contained in the list of appended network addresses within the network message.Type: GrantFiled: March 10, 2022Date of Patent: July 25, 2023Assignee: Ecolab USA Inc.Inventor: David L. Snodgrass

Publication number: 20220358300Abstract: A zone antenna system includes a zone antenna mat including a substantially planar zone antenna and a zone beacon unit configured to establish a detection zone and detect presence of an electronic tag in the detection zone. The zone antenna system may form part of a compliance monitoring system in which presence of the electronic tag the detection zone is part of a monitored process. The zone antenna system establishes a detection zone, detects entry of one or more electronic tags into the detection zone, and stores and/or wirelessly transmits entry event data corresponding to one or more detected entry events for receipt by a remote or local computing device.Type: ApplicationFiled: May 6, 2022Publication date: November 10, 2022Inventor: David L.

Patent number: 11272815Abstract: Monitoring modules for hand hygiene product dispensers may be installed in existing manual or touch free hand hygiene product dispensers to provide wireless communication of dispenser data to or from a dispenser. In one example, a manual dispenser beacon module is configured to be used with a manually actuated hand hygiene product dispenser to monitor hand hygiene compliance events (such as dispense events) associated with the dispenser, and to wirelessly transmit dispenser data to or from the manual dispenser. In another example, a touch free dispenser beacon module is configured to be used with a touch free hand hygiene product dispenser to monitor hand hygiene compliance events (such as dispense events) associated with the dispenser, and to wirelessly transmit dispenser data to or from the touch free dispenser.Type: GrantFiled: March 6, 2018Date of Patent: March 15, 2022Assignee: Ecolab USA Inc.Inventors: Jeffrey Rospierski, David L.

Publication number: 20110273298Abstract: Method and apparatus for monitoring and reporting hand washing at a sanitizing station employs a sensor for signaling the dispensation of a sanitizing agent from a dispenser and setting a clear signal to permit passage through a portal, such as an entrance to a room. The module in turn includes an input element, an output element, a processor, and memory. The module operates in person and administrator modes. In the person mode, the module responds to an input signaling that a person has dispensed sufficient sanitizer to mitigate the spread of germs from care giver/health care worker to patient. The person activates the sanitizer to dispense the sanitizer liquid or foam and that action signals that the cleaning agent has been dispensed and turns on the entrance permitted light. If the dispenser is not activated or the amount of sanitizer dispensed is not adequate to sanitize the person's hands, a sensor positioned at the entrance of the door alarms.Type: ApplicationFiled: January 7, 2010Publication date: November 10, 2011Inventors: David L.
