Abstract: There is provided a housing unit having an immersion detection function, as a housing of an electronic device requiring waterproofing.
A housing unit includes a casing liquid-tightly defining an internal housing space and housing an internal device in the housing space, and an immersion detector that detects whether liquid leak into the housing space of the casing. The casing includes a sealing means for waterproofing a joint, an entryway, or an opening. The immersion detector includes an electrolyte salt and a continuity detector that detects a change in conductivity when the liquid comes into contact with the electrolyte salt. The electrolyte salt is arranged inside the casing and further inside the casing than the sealing means.-

Abstract: A radar metrology system is provided for use with a movement system (e.g., a robot arm) that moves an end tool, and includes mobile and stationary radar configurations. The mobile radar configuration includes mobile radar components that are coupled to the end tool or an end tool mounting configuration. The stationary radar configuration includes stationary radar components (e.g., which define a metrology frame volume that surrounds a movement volume in which the end tool is moved). Distances are determined between stationary radar components and mobile radar components based at least in part on radar signals, wherein the distances indicate (e.g., and may be utilized to determine) a position and orientation (e.g., of the mobile radar configuration and/or end tool). The radar signals are either transmitted from stationary radar components and received by mobile radar components, or transmitted from mobile radar components and received by stationary radar components.

Abstract: A measurement method of a surface shape includes combining N stacked images captured while scanning the measuring head. For a position in the N stacked images, from an integral curve including values of N points, which is obtained by integrating square values or absolute values of the interference signal including values at N points: a start-point-side noise part straight line that approximates a start-point-side noise part, which corresponds to a range where the slope is smaller than the slope in the vicinity of the measurement target surface at the start-point-side than the measurement target surface; an end-point-side noise part straight line that approximates an end-point-side noise part, which corresponds to a range where the slope is smaller than the slope in the vicinity of the measurement target surface at the end-point-side than the measurement target surface; and a surface proximity straight line that approximates surface proximity part.

Abstract: An indenter reference that is brought into contact with an axial second side surface of a sample which is arranged further toward an axial first side than an indenter, the indenter reference serving as a position reference for the indenter; a holder that detachably holds the indenter reference and is coupled with the indenter reference; an indenter position detector that couples with the holder and detects a relative position of the indenter with respect to the indenter reference; a regulator that allows displacement between a first position that regulates movement of the indenter reference with respect to the holder and a second position where the indenter reference can be removed from the holder; and a biasing portion that biases the regulator to be kept at the first position.

Abstract: A scanning probe for a coordinate measurement machine includes a stylus suspension module, a stylus position detection module, a disruptor configuration, and a signal processing and control circuitry module. The stylus position detection module includes a sensor configuration, which comprises various coils, and a shield configuration that is located around the sensor configuration and comprises electrically conductive material for shielding the sensor configuration. The stylus position detection module is mounted to the stylus suspension module utilizing a module mounting configuration, which enables the relative position of the sensor configuration to be adjusted for alignment during the assembly of the scanning probe.

Abstract: A workpiece holder is configured to hold a workpiece and is utilized in a metrology system which includes a sensing configuration for obtaining 3-dimensional surface data for the workpiece. The workpiece holder includes at least three reference features (e.g., spherical reference features extending from sides) that are configured to be sensed by the sensing configuration when the workpiece holder is in different orientations (e.g., as rotated 180 degrees between first and second orientations for presenting front and back sides of the workpiece towards the sensing configuration). A determination of 3-dimensional positions of the reference features for each orientation enables a combining (e.g., in a common coordinate system) of 3-dimensional surface data that is acquired for the workpiece in each orientation. Interchangeable workpiece holding portions may be provided that fit within the workpiece holder for holding workpieces with different characteristics (e.g., having different sizes and/or shapes).
