An electronic device according to the present invention is an electronic device which is capable of performing eye proximity sensing to sense contact of an eye with an eyepiece and line of sight detection to detect a line of sight, including: an eye proximity sensing sensor configured to receive light for the eye proximity sensing; a line of sight detection sensor configured to receive light for the line of sight detection, the line of sight detection sensor being separate from the eye proximity sensing sensor; and one or more light sources including a light source used for both the eye proximity sensing and the line of sight detection.

The length of a moving body made of a material that hardly reflects laser light is measured with high accuracy.

First point cloud information based on three-dimensional point cloud information of a first region A1 of a moving body path RW in which a movement direction is set, second point cloud information based on three-dimensional point cloud information of a second region A2, and third point cloud information based on three-dimensional point cloud information of a third region A3 downstream of the second region A2 are acquired in a time series. A velocity VAM of a moving body AM is calculated based on a temporal change of the first point cloud information A1. A front end position FE of the moving body AM at a first time T1 is calculated based on the second point cloud information A2. A rear end position RE of the moving body AM at a second time T2 is calculated based on the third point cloud information A3. A length LAM of the moving body is calculated based on the velocity VAM of the moving body, the front end position FE of the moving body AM at the first time T1, and the rear end position RE of the moving body AM at the second time T2.

The present invention provides a sump pump system, including a sump pump monitor and application. The sump pump system includes a sump pump. Components of the sump pump system are installed in and/or near a sump. The sump collects liquid, such as water, from an inlet pipe. The sump pump is operable to remove water from the sump. The sump pump is fluidly connected to a discharge pipe. The discharge pipe is operable to carry water from the sump pump to a storm sewer or other discharge point.

An agricultural implement wear monitoring system that monitors a first component of an agricultural implement. A sensor detects and emits a signal indicative of a first geometric dimension of the first component and/or a second geometric dimension of the first component relative to a second component. A controller couples to the sensor. The controller monitors the first geometric dimension and/or the second geometric dimension, and in response to a detected change in the first geometric dimension and/or the second geometric dimension determines a remaining service life of the first component.

A simple, compact and low-cost passive optical transceiver device with four terminals may be used in an optical transmission system with polarization-diversity coherent detection scheme. The transceiver is composed of a first polarization splitter/combiner, a non-reciprocal polarization rotator and a second polarization splitter/combiner. The device simultaneously operates as a transmitter and a receiver with optical signals propagating along opposite directions wherein non-reciprocal polarization rotation leads to distinct effects. The received optical signal is thus split into two orthogonal polarization components directed towards two separate ports.

The LIDAR system includes a first transform component configured to perform a complex mathematical transform on first signals. The LIDAR system also includes a second transform component configured to perform a real mathematical transform on second signals. Electronics are configured to use an output of the first transform component in combination with an output of the second transformation component to generate LIDAR data. The electronics are further configured to use a peak in the output of the first transform component to identify the peak in the output of the second transform component that is located at the beat frequency of the second signals.
