  • Patent number: 10877081
    Abstract: 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.

  • Patent number: 10878301
    Abstract: 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.

  • Patent number: 10852705
    Abstract: 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.

  • Patent number: 10718642
    Abstract: A method for checking an operability of two-wire measuring transducers in automation technology which output a measurement signal as an impressed loop direct current via a two-wire line and active assemblies of which are supplied with electrical energy via the two-wire line includes: measuring the loop direct current and an input voltage of the measuring transducer; increasing the loop direct current in a range from a minimum value to a maximum value independently of the measured value, while measuring the input voltage of the measuring transducer; storing the measured values of the input voltage at selected measuring points of the loop direct current as an individual signature of the measuring transducer; and, during ongoing operation, measuring the input voltage at connection terminals of the two-wire line via an internal resistance of the measuring transducer at a prevailing loop direct current and recursively comparing that with the signature.
