Abstract:
The present invention concerns a method for identifying a user (1) of a signalling unit (2) when said user (1) performs a physical interaction with a user interface (3) of the signalling unit (2), thereby requesting a signalling unit action (12), wherein said user (1) carries an identification tag (4), the method comprising the steps of: a) transmitting, by the signalling unit, a signalling unit message as variations in a magnetic field (5); b) receiving said signalling unit message by the identification tag (6), and subsequently radiofrequently transmitting a tag response message by the identification tag (7), said tag response message comprising identification information of the user carrying said identification tag, c) receiving, by the signalling unit, said tag response message (8), thereby identifying the user requesting the signalling unit action (9), whereby said transmission is initiated upon said physical interaction of the user (1) at the user interface (3) of the signalling unit (2). The present invention also concerns a system for identifying a user (1) of a signalling unit (2), comprising a signalling unit and an identification tag.
Abstract:
The present disclosure relates to electromagnetic marker devices for locating hidden or buried objects. One embodiment includes an antenna having a plurality of conductive windings enclosed in a housing made of a low dielectric constant material and an electronic circuit including a circuit board having circuit elements disposed thereon and electrically coupled to the conductive windings through a connector. The circuit elements receive an input signal having a first frequency from an above-ground transmitter, convert the input signal to a power supply to power up the electronic circuit, generate, in response to the input signal, an output signal having a second frequency different from the first frequency, and provide the output signal, via the antenna element, to an above-ground receiver.

Abstract:
Systems and methods for electronically marking, locating, and virtually displaying buried utilities are disclosed. According to one embodiment, one or more electronic marker devices may be placed below a ground surface in proximity to a buried utility, and marker device data indicative of position and/or identity of such electronic marker devices may be obtained. The obtained marker device data may be associated to the utility data and stored in a database. The stored data may thereafter be retrieved based in part on the marker device data for use in subsequent locate operations and/or for other purposes.
Abstract:
An arrangement for tracking and recording movement of articles between a security enclosure and remote locations which includes releasably retaining the articles in a panel assembly, an electronics panel having a reader for tracking and recording movement of at least one article when the at least one article is moved relative to the panel assembly, taking an article having a unique article identifier and placing the article in a home location via a field of detection of the reader, storing the identity of the article and data indicative of the history and location of the article, allowing authorised users to initiate communications with the security enclosure to determine and track the location and history of movement of the article via an electronic user initiated input device application and creating a record indicative of the movements of the article between a location in said enclosure and remote locations.
Abstract:
Systems for locating buried utilities in conjunction with associated electromagnetic marker devices are disclosed. A marker device may include a marker device antenna and an electronic circuit operatively coupled to the marker device antenna. The electronic circuit may include at least two resonant circuits, including a first resonant circuit formed in combination with the marker device antenna for receiving an excitation signal at a first frequency from a marker excitation device. The received excitation signal may be converted into a power supply by a power circuit for powering the electronic circuit. Responsive to the received excitation signal, a processing element provided in the electronic circuit may generate an output signal at a second frequency, which is different from the first frequency. The generated output signal may be tuned by a second resonant circuit and provided to the marker device antenna.
