Patent number: 11175644Abstract: A distributed automation control system includes a network for connecting members of the system to a central server for communication between the members and the central server. The members can include a device controlled by a microcontroller in communication with the network, a mobile object digitized to communicate with the central server via the network, and a facility component in communication with the central server. A member can be assigned to one or more groups of members for group learning and for generating a group heartbeat. Each member defines a safety volume which is monitored by the central server. When the safety volume of one member overlaps the safety volume of another member, the central server initiates a responsive action which can include ceasing the operation of at least one of the members.Type: GrantFiled: January 25, 2019Date of Patent: November 16, 2021Assignee: BEET, INC.Inventors: David Jingqiu Wang, Aaron Gregory Romain, Daniel Philip Romain

Patent number: 10979333Abstract: A request to monitor a data packet to be transmitted from a first location to a second location over a first network is received. A projected time for the transmission of the data packet from the first location to the second location is determined. Responsive to determining the projected time, whether the data packet arrived at the second location after the projected time plus a variance is determined.Type: GrantFiled: May 12, 2015Date of Patent: April 13, 2021Assignee: International Business Machines CorporationInventors: Andrew J.

Patent number: 10878301Abstract: Systems and methods for operating an Electronic Smart Tag (“EST”). The methods involve: operating the EST in a first operational state in which first item related information is output from an electronic output device of the EST that is powered by an energy storage device storing energy harvested from an external energy source; detecting when a charge level of the energy storage device reaches or falls below a first threshold level; and transitioning an operational state of the EST from the first operational state to a second operation state in which a message is output from EST requesting that a mobile device be placed in proximity to the EST for purposes of obtaining at least a first portion of the first item related information, in response to the detection that the charge level of the energy storage device has reached or fallen below the first threshold level.Type: GrantFiled: April 19, 2017Date of Patent: December 29, 2020Assignee: SENSORMATIC ELECTRONICS, LLCInventors: Mohammad Mohiuddin, Melwyn F.

Patent number: 10877081Abstract: A system and method used to detect voltage by an electric field detector on equipment is provided. The equipment includes a component which is configured to come into direct contact with, or come into proximity of, a conductor of electricity, and a control system which is in operative communication with the component. An electric field detector is provided on the equipment. The detector includes field detection circuitry configured to detect a voltage in an electric field in the environment which meets or exceeds a voltage threshold. When an overvoltage is detected by the electric field detector, the control system of the equipment is configured to act by performing one of 1) activating a warning module on the equipment and 2) causing the component of the equipment to act.Type: GrantFiled: April 26, 2018Date of Patent: December 29, 2020Assignee: GREENLEE TOOLS, INC.Inventors: William J.

Patent number: 10852705Abstract: Devices in an environment may be transitioned to a low power state based on calendar data or other types of user input. User input indicating a first device, a time period, and a set of conditions is received. When the time period occurs, device data from one or more devices in the environment is used to determine whether the set of conditions is met. If the conditions are met, an instruction from a device outside of the environment is provided to the first device to cause the first device to enter a low power state, during which the device is no longer accessible to other devices outside of the environment. After a lapse of the time period, a change in conditions, or in response to manual input provided to the first device, the first device returns to an operational state.Type: GrantFiled: November 21, 2018Date of Patent: December 1, 2020Assignee: AMAZON TECHNOLOGIES, INC.Inventor: Myles Conley
