A technique facilitates detection of gaseous emissions in a marine environment via a vessel or vessels traversing a region of the marine environment. Environmental data is collected via a detection system on each vessel and communicated to a processing system. The processing system processes various environmental data such as location data, emission detection data, wind data, and/or other data to determine an emissions result. This emissions result is output in a form to facilitate decision-making with respect to potential corrective actions to reduce the gaseous emissions.

When a vehicle control interface receives information indicating “Standstill” from a VP, the vehicle control interface sets a value 2 in a signal indicating an actual moving direction. When the number of wheels rotating in a forward rotation direction is larger than two, the vehicle control interface sets a value 0 in the signal indicating the actual moving direction. When the number of wheels rotating in a reverse rotation direction is larger than two, the vehicle control interface sets a value 1 in the signal indicating the actual moving direction. When the number of wheels rotating in the forward rotation direction is equal to the number of wheels rotating in the reverse rotation direction, the vehicle control interface sets a value 3 in the signal indicating the actual moving direction. The vehicle control interface provides the signal indicating the actual moving direction to an ADK.

A rotation detecting apparatus includes a rotating member, detectors regarding a rotating direction of the rotating member, and a predetermined unit. Each detector detects whether a predetermined standard direction is included in detecting ranges different for each rotating member and outputs a result. The predetermined unit combines the detection result output from each detector and extracts an angle range. The predetermined unit specifies the rotating direction of the rotating member based on changes in the angle ranges extracted a plurality of times occurring in the plurality of times. The detecting range corresponding to each of the plurality of detectors is determined to be able to identify relative positions before and after a change from the angle range extracted by the predetermined unit to the angle range that is clockwise or counterclockwise apart a predetermined number or less to the angle range extracted, the predetermined number being two or more.

An encoder includes a code disc and a processor communicatively coupled with the code disc. The code disc is configured to rotate along with a rotating object and includes a plurality of fan teeth extending radially. One of the plurality of fan teeth is different from other ones of the plurality of fan teeth, and the other ones of the fan teeth are same to each other. A first portion of a detection signal that is generated in one rotation of the code disc, corresponding to the one of the plurality of fan teeth, is different from a second portion of the detection signal, corresponding to each of the other ones of the fan teeth. The processor is configured to detect the rotation of the code disc to obtain the detection signal and a rotation parameter of the rotating object based on the detection signal.

A method is provided for supporting flight operations of vertical takeoff and landing (VTOL) aircraft in an urban air mobility (UAM) environment that includes a vertiport. The method includes accessing first observed weather data obtained by sensors located on-site at the vertiport and second observed weather data obtained by sensors onboard VTOL aircraft. A data fusion is performed to integrate the first observed weather data and the second observed weather data to produce a collection of weather data that describes the weather in an environment of the vertiport, and an environment of the VTOL aircraft. And a weather map is produced based on the collection of weather data, the weather map illustrating one or more meteorological features of the weather in the environment of the vertiport and/or the VTOL aircraft, the weather map produced for use in supporting flight operations of the VTOL aircraft.

An inventory management system for automatically generating a restocking order or prompting generation of a restocking order includes a storage structure defining a stock storage space, a divider pivotable on the storage structure, a divider pivotable on the storage structure between a first position in which the stock storage space is divided into first and second sections, and a second position in which the stock storage space is undivided, and a motion detector module having a motion sensor in communication with a radio frequency transmitter for generating a stock reorder signal.

A travelling direction calculation apparatus includes an acceleration sensor, a period identification unit, an action determination unit, a vector calculator, and a travelling direction decision unit. The period identification unit identifies a stable measurement period and an idling leg period based on change in a vertical component of acceleration detected by the acceleration sensor. The action determination unit discriminates between walking and running by using the minimum value of the vertical component of the acceleration in the idling leg period. The vector calculator calculates a velocity vector from a horizontal component of the acceleration in the stable measurement period. The travelling direction decision unit decides a direction of traveling of a user based on a result of determination performed by the action determination unit and the velocity vector calculated by the vector calculator.
