    Abstract: A receiver (30) for providing an activation signal (54) to transition a device from a dormant state to an operative state. The receiver includes a sensor (32), a super regenerative oscillator, SRO, circuit (34), and a processing device (36, 38). The sensor is one of an optical sensor, an acoustic sensor, and a magnetic field sensor, and generates detector signals (40) based on wireless signals (28) received from an external source (18). The SRO circuit is electrically coupled to the sensor to receive the detector signals, and electrically oscillates with a constant SRO frequency and with a SRO amplitude (As) that changes when a carrier frequency of the detector signal substantially matches the SRO frequency. The processing device monitors the SRO amplitude in time, and generates the activation signal when a temporal characteristic (Sc) of the monitored SRO amplitude matches a predetermined reference pattern (52).

  • Publication number: 20210123717
    Abstract: Method for determining a spatial property of a submerged object in a 3D-space, using an underwater moveable platform, that is provided with a camera and with a position and orientation measurement system configured to output a position and orientation of the camera. The method includes receiving user input for visually fitting a bounding volume to the object, and determining the spatial property of the object based on a corresponding spatial property of a bounding volume once the user is satisfied that the bounding volume sufficiently fits the object. The method provides an interactive manner of visually fitting the bounding volume to the object, based on images of the object taken at different positions and/or orientations of the camera relative to the object, as well as on a representation of a position and orientation of the camera in the 3D space at the time each image was captured.

  • Publication number: 20210108723
    Abstract: A method and sensor system for monitoring in time a geometric property of a gasket (32, 34) that sealingly interconnects two structural members (20, 21) of a subterraneous or immersed tunnel (10). The system includes a sensor (42) for measuring position indications for surface portions (48) of the gasket relative to a reference (26, 27, 47) associated with one or both structural members, and a processor (44) that is coupled with the sensor to receive the position indications. The processor is configured to derive indications of displacement (?Y) for each of the gasket surface portions based on the measured indications of position, to compare the indications of displacement for each of the gasket surface portions with at least one threshold value (Ty), and to generate a warning message for an operator if at least one of the indications of displacement transgresses the at least one threshold value.

  • Publication number: 20210041220
    Abstract: A camera monitors positions on an external object having a beacon (1(i), i=1, 2, . . . , I; 130; 430) attached to it. The apparatus has at least one image sensor (120; 321, 322; 420; 520), an imaging optical element (101) for projecting light on the image sensor (120), and a processing unit (9). The imaging optical element (101) may be non-refractive and receives a light beam (5(i); 131) transmitted from the beacon (1(i); 130; 430) and transfers the light beam (5(i); 131) to the image sensor (120; 321, 322; 420; 520). The image sensor (120; 321, 322; 420; 520) forms image data based on the received light beam (5(i); 131) and background light. The processing unit (9) processes the image data such that it filters image data components relating to the background light and renders image data components relating to the light beam.
