An appliance, such as a refrigerator appliance, and controller configured to perform operations of a method for measuring contents in a container are provided. The operations include receiving, from a sensor, one or more signals indicative of a height of contents in a container, and determining a contents volume in the container based at least on the height of contents in the container.

A system for stand-off screening of individuals and/or an item of baggage carried by an individual. The system including: a sensor array, the sensor array including: an optical sensor, configured to collect data indicative of a position of the individual and/or the presence and dimension of the item of baggage relative to the optical sensor; a first radar sensor, configured to collect data indicative of: properties of objects concealed under clothing worn by the individual and/or properties of one or more objects within the item of baggage; an acoustic sensor, configured to collect data indicative of: properties of objects concealed under clothing worn by the individual and/or properties of one or more objects within the item of baggage. The system also includes a processor, configured to combine the data collected from the optical sensor, the first radar sensor, and the acoustic sensor, and to derive a risk estimation for the individual and/or the item of baggage carried by the individual based on the combined data.

A concrete pump (1) includes a first frame (2a) equipped with a hopper (5) intended to receive the concrete, feet (13) for stabilizing the concrete pump (1) and a turret (10) carrying an articulated boom (6) comprising a plurality of arms (7). The articulated boom (6) carries at least one pipe (6a) for conveying the concrete between the hopper (5) and a concrete delivery location. The concrete pump (1) is equipped with any one of at least a first device for detecting cavities in the ground, a second device (22) for detecting an inclination of at least one arm (7) relative to a vertical axis (A2), a third device for detecting the deployment of the feet (13), a fourth device for detecting an attitude of the concrete pump (1) and a rotation sensor equipping the turret (10).

The present invention relates to a method for detecting a thickness of a tree canopy based on an ultrasonic echo signal, and belongs to the technical field of agricultural machinery information sensing and detection. The present invention analyzes and discriminates a first effective peak and a last effective peak of the ultrasonic echo signal, obtains a first effective peak time and a last effective peak time, and calculates the thickness of the tree canopy according to a provided calculation formula, thus realizing the direct detection of the thickness of the tree canopy. This method has characteristics such as a high accuracy and a wide application range, and is applicable to the field of detection of the thickness of a tree canopy in industries such as agricultural machinery and forestry machinery.

A cargo detection system for detecting overhanging cargo on a motor vehicle comprises a sensor system configured to provide cargo measurement data for cargo loaded onto the motor vehicle by measuring at least one of exterior dimensions of cargo protruding over an outer edge of the motor vehicle and an opening condition of a tailgate of the motor vehicle. The system further comprises a control device configured to assess, based on the cargo measurement data of the sensor system, whether cargo is overhanging from the motor vehicle and to calculate an updated vehicle length and/or vehicle width for the motor vehicle accounting for the overhanging cargo.

A substrate transport apparatus includes: a support configured to support a substrate; a moving mechanism configured to move the support in a lateral direction in order to transport the substrate from a first placement portion to a second placement portion, each of the first placement portion and the second placement portion being configured to place thereon the substrate; and an ultrasonic sensor provided on the support and configured to detect the substrate placed on the first placement portion.

A vehicle flow monitoring system for detecting both a car count and direction of movement of vehicles passing a point of interest. The vehicle flow monitoring system generally includes a car counter which may include a microcontroller and a pair of distance sensors. Each of the distance sensors is oriented toward a unique point of interest. Each of the distance sensors includes a threshold distance reading which is used to detect whether a vehicle has passed underneath the car counter. The system may determine direction of travel of the vehicle based on which of the distance sensors is passed by the vehicle first. The microcontroller may assign an Event ID to each time a vehicle passes each of the sensors, with the Event ID being used to identify when and if the vehicle should be counted, or whether a non-vehicle object has passed the car counter.

A device for the detection of an at least partial flooding of a motor vehicle. The device includes an ultrasonic sensor that is designed to transmit and to receive ultrasonic signals. The device also includes an electronic recognition device, which can recognize an at least partial flooding of the motor vehicle on the basis of an ultrasonic signal received by the ultrasonic sensor. The recognition device is designed to determine the amplitudes of ultrasonic signals received within a defined time window, and to compare the amplitudes to a defined threshold value. The recognition device is designed to detect a flooding of the ultrasonic sensor as a function of the result of the comparison.
