Abstract: An imaging system for obtaining images having enhanced features is described. The imaging system includes an optical system that receives and direct light from a field of view to two or more image planes. The image planes are optically coupled and configured to detect at least a portion of the received light and generate image data corresponding to the field of view. The system can include a processor that receives the image data generated by each plane and combines the data to form a combined image. The combined image can have a higher resolution than any image that can be obtained from the individual image sensors and the image plane may be curved to reduce the cost of optics. The processor can detect objects (e.g., moving objects) contained in images obtained from one image plane and configure the other image planes to obtain more detailed images of the detected objects.

Abstract: There is provided a device control apparatus which makes it possible to dispense with device monitoring (polling) by a client apparatus to thereby reduce traffic on a network. A device server 200 acquires, according to device information for identifying a device locally connected to the device server 200, at least one of a trigger detection algorithm and a definition file for monitoring a state change of the device identified based on the device information, and monitors the locally connected device based on at least one of the acquired trigger detection algorithm and definition file. Then, when a state change of the device is detected, the device server 200 sends a trigger notification indicative of the detection of the state change to a client PC 100 via a network 500, and starts a session with the client PC 100 in response to a connection request from the client PC 100 having received the trigger notification.

Abstract: Magnetometers under the road surface detect variations in the vertical and longitudinal horizontal components of the magnetic field over time in response to passing vehicles. A trajectory of these components in the phase space of these field components is regularized to obtain a magnetic signature. Magnetic signatures are compared using cross-correlation over arc length to identify vehicles. Inductance sensors can be used to detect vehicles and help determine the beginning and end of magnetic signatures.

Abstract: A device control apparatus which monitors a state change of a device independently without communication with a client apparatus. A device server as the device control apparatus monitors the state of a device locally connected thereto, using a definition file and a trigger detection algorithm for monitoring the state of the device, and detects a state change of the device. When a state change of the device is detected, the device server transmits a trigger notification indicative of the detection of the state change to the client apparatus. The device server starts a session with the client apparatus having received the trigger notification and relay data communication with the device, of which the state change has been detected. When the session with the client apparatus is disconnected, the device server restarts monitoring of the state of the device.
