    Abstract: Disclosed herein is a method including: providing a light guiding arrangement (LGA) configured to redirect light, incident thereon in a direction perpendicular to an external surface of the sample, into or onto the sample, such that light impinges on an internal facet of the sample nominally normally thereto; generating a first incident light beam (LB), directed at the external surface normally thereto, and a second incident LB, parallel to the first incident LB and directed at the LGA; obtaining a first returned LB by reflection of the first incident LB off the external surface, and a second returned LB by redirection by the LGA of the second incident LB into or onto the sample, reflection thereof off the internal facet, and inverse redirection by the LGA; measuring an angular deviation between the returned LBs and deducing therefrom an actual inclination angle of the internal facet relative to the external surface.

    Abstract: A tilt indicator includes a tilt detection assembly including a mass movable from a first position to a second position in response to a tilt event. A capacitance sensor circuit is disposed proximate the first position. The capacitance sensor circuit is configured to output a capacitance value based on the mass being in the first position. A module and logic integrated with and/or executable by the module is coupled to the capacitance sensor circuit, the module configured to output, when energized, an indication of an actuation state of the tilt indicator based on the capacitance value. The capacitance sensor circuit may be energized from by a wireless communication module, such as an RFID chip, by a remote reader device.

    Abstract: A laser marking system in one aspect of the present disclosure includes a laser marker, a beam receiving device, and a notifier. The laser marker includes a laser beam emitter. The beam receiving device includes a beam receiver and a transmitter. The beam receiver receives a laser beam emitted by the laser beam emitter. The transmitter transmits a first positional signal. The first positional signal indicates a receiving position of the laser beam in the beam receiver. The notifier notifies of the receiving position of the laser beam based on the first positional signal.

    Abstract: A laser square including a frame, a hub, and tabs. The frame has a first side and a second side. The hub extends from the first side and supports a laser level. The laser level is configured to project a laser. The tabs are adjustably coupled on the second side of the frame. Each of the tabs is independently rotatable between a first position and a second position to selectively align the frame with a corresponding edge of a workpiece.

    Abstract: A trowel (10) is equipped with an optical detector (13) that detects a laser beam (12). The optical detector (13) may be arranged detect the laser beam (12) only when aligned with the laser beam (12). The trowel (10) provides feedback to the user when it detects the laser beam (12) and when it does not. The feedback may be a sound, a light or a haptic feedback. When the trowel (10) is used for constructing a tapered floor, such as in a bathroom, the laser beam (12) may be originated from a laser level (40) arranged on a support (30). The support (30) is positioned inside a floor drain (32), for example a bathroom floor drain (32).

    Abstract: An approach is provided for detecting an on-boarding or off-boarding event based on mobile device sensor data. The approach, for example, involves retrieving sensor data collected from at least one sensor of a mobile device that is fixed in a stationary position relative to a vehicle. The approach also involves processing the sensor data to determine roll angle data for the vehicle over a time window. The approach further involves processing the roll angle data to determine one or more transitions of a roll angle value of the vehicle between one or more value levels. The approach further involves determining an on-boarding event, an off-boarding event, or a combination thereof based on the one or more transitions. The approach further involves providing the on-boarding event, the off-boarding event, or a combination thereof as an output.

    Abstract: A high-precision dual-axis laser inclinometer based on wavefront homodyne interference and a measuring method are disclosed. The method includes: obtaining a laser signal through a laser light source module, transmitting the laser signal to an integrated sensing module, and generating a wavefront interference signal based on the integrated sensing module; and inputting the wavefront interference signal into a signal processing module for performing high-precision decoupling operation to obtain a horizontal inclination angle measurement result. The measurement resolution is high, the measurement result can be directly traced to the laser wavelength, high-precision dual-axis inclination angle measurement can be realized only by using single-beam measurement light, meanwhile, the laser inclinometer has the advantages of being simple in structure, simple in light path, easy to integrate, beneficial to engineering implementation, and high in cost performance, and the requirement of high-end equipment on the ultra-precision inclinometer is met.
