Abstract: The invention relates to a device having, as a sensor for detecting an object arranged behind an article that is transparent to electromagnetic radiation, a coil assembly having a first transmitting coil (1.1) and a first receiving coil (2.1) arranged orthogonally with respect to the first transmitting. An evaluation unit evaluates the output signals from the coil assembly. The fact that the coil assembly comprises the first transmitting coil (1.1) and at least one further transmitting coil (1.2, 1.3, 1.4), and the first receiving coil (2.1) and at least one further receiving coil (2.2, 2.3, 2.4), wherein axes (1.5, 1.6) of the first and of the at least one further transmitting coil are orthogonal to each other, and the axes (1.5, 1.6) of the first and second transmitting coil intersect the axis (2.5) of the first receiving coil (2.1) that is orthogonal to the first and second transmitting coils (1.1, 1.2), means that a device is provided that reduces or even eliminates the grating effect.

Abstract: The invention relates to a method and a measuring arrangement for detecting an object (3) hidden behind an article (1). The method comprises the following steps: applying a first alternating voltage (5) to a first sensor (7); applying a second alternating voltage (9) to a second sensor (11) arranged adjacent to the first sensor (7); determining an effect (15) of the article (1) on at least one of the alternating voltages (5, 9) depending on a distance (13) of the sensor (7, 11) to the article (1); determining a change (17) in the dependent effect (15) occurring during a movement (19) of the sensor (7, 11) along the article (1); and detecting the object (3) in accordance with the change (17) of the dependent effect (15).

Abstract: A surface marking tool, comprising a housing a sensor coupled in the housing to identify a specific location on a surface a marker having a back end and an engaging end, whereby the back end is coupled to the underside of the housing and the engaging end extends beyond the underside of the housing to engage with the target surface; and at least one foot coupled to the underside of the housing. Another aspect of the present invention includes a surface marking tool, comprising a housing, a sensor coupled in the housing to identify a specific location on a surface, a marker having an engaging end, whereby the marker is housed in an open faced cartridge with a back end, whereby the engaging end of the marker extends beyond the cartridge to engage with the target surface, and the back end of the cartridge is coupled to the underside of the housing and extends beyond the underside of the housing, and at least one foot coupled to the underside of the housing.

Abstract: An implementation of a system, device and method for projecting a visual indicator against a surface is provided. A display projection system in a handheld sensor device (e.g. a handheld wall scanner) projects a static or computer-controlled dynamic pattern of light onto a surface being scanned to indicate a specific feature, such as existence of solid structures of wood, metal or plastic, electric or magnetic fields, or a disturbance of a field. The projected light may be controlled by a computer via an aperture to allow flexibility in what is projected, such as icons, lines, graphics, characters and colors.

Abstract: An implementation of systems, devices and methods for a sensor to find a hidden element behind a surface are provided. The sensor includes a housing with a radiant indicator in a bottom section of the housing. The radiant indicator is translucent and acts as another indication that the sensor is over the hidden element. The sensor also includes a light source, such as an LED, which lights the radiant indicator with a beam, as well as optionally projecting an image on the surface, for example, formed by the bottom section and a top section of the housing. The same light source may also be used to project a second beam to an indicator on the top section of the housing.
