摘要： Systems and methods for determining a presence of cargo within a container are described. The determination may comprise transmitting a first electromagnetic signal within the container and receiving a first reflected electromagnetic signal corresponding to the first electromagnetic signal. The first reflected electromagnetic signal may be converted into a set of first magnitude values corresponding to a set of bin values representing a respective distance from the radar device. The first magnitude values may be integrated, using a moving window, over successive subranges of bin values to produce a set of integrated magnitude values. A set of integrated base magnitude values may be subtracted from the set of integrated magnitude values to produce a set of normalized integrated magnitude values. A presence of cargo within the container may then be determined by comparing each of the normalized integrated magnitude values with corresponding threshold values.

摘要： In some examples, a sensor device is to mount to a barrier pivotable between an open position and a closed position, the barrier being on a moveable platform. The sensor device includes an accelerometer to measure acceleration data and a rotation sensor to measure rotation about an axis. The sensor device includes at least one processor configured to determine an open/close status of the barrier based on the acceleration data and the rotation data, and an orientation of the moveable platform.

摘要： Methods, devices and sensors for detecting a gesture are described. In an embodiment, a gesture sensor includes a time of flight sensor having a sensing element configured to generate an electrical signal responsive to received light. The time of flight sensor also includes a light source for emitting a burst of light. The sensing element has a sensing side for receiving light and a non-sensing side which is opposite the sensing side. The gesture sensor also includes one or more light inhibitors positioned relatively nearer the sensing side of the sensing element than the non-sensing side. The light inhibitors are asymmetric about a first center line of the sensing element. The first center line is located midway between first and second sides of the sensing element. The gesture sensor further includes a processor coupled to the time of flight sensor configured to detect a gesture.
