The application concerns an apparatus for inspecting luggage, including a tubular frame having a plurality of pairs of lateral openings, the tubular frame being suitable for receiving a plurality of containers in line with the pairs of openings, each of the containers having two opposing faces and a plurality of juxtaposed and superimposed locations that are freely accessible through the two opposing faces, each of the locations being suitable for receiving a piece of luggage provided with an information recording medium containing information relating to the piece of luggage. The apparatus further includes a locating device including photoelectric detection grids installed across the lateral openings, respectively, and the position of the location in the container is recorded when the photoelectric detection grid is crossed.

Object-sensing systems including a light transmitter subsystem and a light receiver subsystem. The light transmitter subsystem main be configured to generate a collimated linear beam of light at a predetermined wavelength and having a length of at least 3 inches. The light receiver subsystem may include a linear sensor array having a length of at least 3 inches. The linear sensor array may be positioned to receive the collimated linear beam of light and to detect shadows caused by objects blocking at least a portion of the collimated linear beam of light. Various other systems and methods are also disclosed.

A visible light sensor may be configured to sense environmental characteristics of a space using an image of the space. The visible light sensor may be controlled in one or more modes, including a daylight glare sensor mode, a daylighting sensor mode, a color sensor mode, and/or an occupancy/vacancy sensor mode. In the daylight glare sensor mode, the visible light sensor may be configured to decrease or eliminate glare within a space. In the daylighting sensor mode and the color sensor mode, the visible light sensor may be configured to provide a preferred amount of light and color temperature, respectively, within the space. In the occupancy/vacancy sensor mode, the visible light sensor may be configured to detect an occupancy/vacancy condition within the space and adjust one or more control devices according to the occupation or vacancy of the space. The visible light sensor may be configured to protect the privacy of users within the space via software, a removable module, and/or a special sensor.

An example system for determining space availability in an aircraft includes a plurality of laser sensors configured to be positioned in a baggage container at a first wall and a second wall, and the first wall and the second wall face each other. The plurality of laser sensors emit signals within the baggage container and detect reflected responses to generate outputs. The system also includes one or more processors in communication with the plurality of laser sensors for executing instructions stored in non-transitory computer readable media to perform functions including receiving the outputs from the plurality of laser sensors, mapping contents of the baggage container based on the outputs from the plurality of laser sensors, and based on said mapping, outputting data indicative of occupied space in the baggage container.

Crosstalk mitigation among cameras in neighboring monitored workcells is achieved by computationally defining a noninterference scheme that respects the independent monitoring and operation of each workcell. The scheme may involve communication between adjacent cells to adjudicate non-interfering camera operation or system-wide mapping of interference risks and mitigation thereof. Mitigation strategies can involve time-division and/or frequency-division multiplexing.

There is provided a method of automatically supervising a transfer operation of a transfer device including an optical sensor, the optical sensor having a light emitting part and a light receiving part provided in a head of a holding part for holding a substrate, the method including: acquiring a change in intensity of a first reflected light reflected off a first object by radiating a light from the light emitting part toward the first object below the holding part and receiving the first reflected light reflected off the first object by the light receiving part, while horizontally moving the holding part; and specifying an end position of the first object based on the change in intensity of the first reflected light.

An object counting device adjusts a signal to account for noise to improve object counting accuracy. A controller receives an electromagnetic radiation (e.g., light) intensity signal from radiation detectors and determines that its value is within a voltage threshold, thereby indicating that no object is passing through the radiation. The controller determines a derivative of the signal and that the derivative is less than a derivative threshold level for at least a predefined time. The controller then updates a base noise floor value to be the value of the radiation intensity signal to account for particles within a path of the electromagnetic radiation to improve an object counting accuracy. In some embodiments, the processor can scale the received radiation intensity signal in accordance with the updated base noise floor value.
