An inductive sensor device (23) having a scale unit (24) and a sensor unit (25) that can be moved relative to each other in a measuring direction (M) is described. The scale unit contains scale elements (26) that are adapted to create a field pattern (P(x)) in measuring direction (M) that is detected by means of a receive circuit (35) of the sensor unit (25). The receive circuit (35) contains at least a first receive coil set (36) and a second receive coil set (37) that are offset in measuring direction (M). In so doing a first spatial phase and a second spatial phase receive signal is provided by these receive coil sets (36, 37) respectively. These spatial phases can be used for absolute position determination.

This disclosure relates to a defect gauge instrument and method for repairing bone defects. The defect gauge instrument disclosed herein may be utilized to determine one or more characteristics of a bone defect prior to positioning a graft and/or implant at a surgical site.

A tool for determining variations in outer diameter of a pipe. The tool may have a pair of contact arms configured for engaging with opposing sides of a pipe. The contact arms may be biased toward one another, and at least one of the arms may be configured to slide toward and away from the other. As the contact arms are moved along an outer surface of a pipe, a distance between the arms may change in response to variations in outer diameter of the pipe. A plunger gauge may be arranged on one of the contact arms with its plunger directed toward the other arm. The plunger may extend or depress in response to a decreased or increased distance between the contact arms. An alignment shoe may align the contact arms with at least X and Z axes of the pipe so as to help ensure accurate pipe measurements.

Smart Scale Ruler is an electronic architect's scale having a triangular shaped ruler body. The Smart Scale Ruler has a changeable electronic display for displaying a custom or the desired scale of any unit of length, for a document or plan. A set of depressible buttons function as the inputs for the value of the reference point a user wishes to base the custom scale off of, as well as different settings for the device, in order to display the correct scale on the electronic display.

A length measuring apparatus for use in combination with a cutting device having a cutting blade to measure length of a workpiece cut by the cutting blade comprises a slide rail which is secured relative to the cutting device when length is measured; and a sliding unit that is slidably mounted to the slide rail, the sliding unit having a sliding body, a length measuring unit that measures distance along which the sliding body slides relative to the slide rail, and an arm member that comes in contact with the workpiece when the workpiece is placed at a cutting position; wherein the sliding unit further comprises an angle gauge member, mounted at that tip portion of the arm member which comes in contact with the workpiece, that comes in contact with the cutting blade and measures a cutting angle of the cutting blade.

A tool for detecting a covered edge of a structural member through sealant material of a fillet seal includes an edge detection probe mounted to a fixture. The probe outputs an interrogation signal toward the covered edge and receives a return signal indicative of a location of the covered edge. The tool includes an electronic control unit (ECU) in communication with the edge detection probe and a display screen. The ECU is configured to generate, from the return signal, one or more XY coordinates indicative of the edge location, and to display the edge location on the display screen. Additionally, the tool includes a seal measurement device. In response to the edge location, the device measures a predetermined dimension of the fillet seal, including a thickness and/or a shape of the fillet seal. A method includes detecting the covered edge using the tool.

An electromagnetic induction type encoder, wherein at least one of widths of a first transceiver coil, a first plurality of conductors and a first receiver coil of a first track in a direction vertical to facing direction between a detection head and a scale and a measurement direction is different from corresponding width of a second transceiver coil, a second plurality of conductors and a second receiver coil in the direction vertical to the facing direction and the measurement direction.

Methods and apparatus to count people are disclosed. Example people counting apparatus disclosed herein include a difference calculator to calculate a degree of similarity between a first characteristic dataset and a second characteristic dataset representative of face detections in images. Disclosed example people counting apparatus also include a limiter to store the first characteristic dataset and the second characteristic dataset in a plurality of characteristic datasets associated when the degree of similarity does not satisfy a threshold, and to store the first characteristic dataset in the plurality of characteristic datasets and discard the second characteristic dataset when the degree of similarity satisfies the threshold to limit a number of stored characteristic datasets. Disclosed example people counting apparatus further include a comparator to compare the plurality of characteristic datasets to each other to determine a number of unique faces in an environment during a first period of time.

An apparatus reads a value measured with an analog measuring tool. The apparatus includes an imaging unit for obtaining a captured image of the analog measuring tool that is indicating a measured value, a retaining unit for retaining a 3D model of the analog measuring tool, a matching unit for specifying a 3D model matching the captured image, a guidance unit for outputting guidance information for correcting orientation of the analog measuring tool based on the matched 3D model, a reading unit for reading the measured value from the captured image to generate a measurement result, and an output unit for outputting the measurement result.
