Abstract: A system for detecting driving violations on a roadway in real time includes spaced apart cameras and spaced apart presence sensors which generate timestamp signals when detecting passing vehicles. A GPS module and a communication module are operatively connected to a computer monitoring unit which determines the driving violations. A photographic image is taken of each vehicle which is committing a driving violation and the image and a violation report is transmitted to a transit authority. The system may be a static system mounted in the median of a roadway or may be a dynamic system mounted in a monitoring vehicle. The driving violations may be one of speeding, tailgating, street racing, improper passing, and lane blocking.

Abstract: A method for designing an image filter, the method being executed by a machine learning algorithm (MLA), the method comprising: receiving unfiltered images, a desirable visual task and an undesirable visual task; for each unfiltered image, receiving a first label indicative of whether the desirable visual task is accomplishable and a second label indicative of whether the undesirable visual task is accomplishable; filtering the unfiltered image using a virtual filter model representative of the image filter; using the filtered images, training the MLA to perform the desirable visual task and prevent the undesirable visual task to be performed; using test images, determining a first efficiency for the MLA to perform the desirable task and a second efficiency for the MLA to prevent the undesirable task; adjusting a parameter of the virtual filter model based on the first and second efficiencies; and outputting the adjusted parameter.

Abstract: A system for detecting aggressive driving on a roadway in real time includes spaced apart cameras and spaced apart presence sensors which generate timestamps when detecting passing vehicles. A GPS module and a communication module are operatively connected to a computer monitoring unit which determines the aggressive driving. A photographic image is taken of each vehicle which is driving aggressively and the image and a violation report is transmitted to a transit authority. The system may be a static system mounted in the median of a roadway or may be a dynamic system mounted in a monitoring vehicle. The aggressive driving violations may be one of speeding, tailgating, street racing, improper passing, and lane blocking.

Abstract: Sound diffusers are important components in enhancing the quality of room acoustics. The present disclosure relates to a sound diffuser obtained by using properties of the cymatics phenomena. Cymatics is the study of sound and vibration made visible, typically on the surface of a plate, diaphragm or membrane. Two examples of diffusers are designed by the cymatic shapes and modeled by using a quadratic quadratic residue sequence. It is found that this type of acoustic diffusers can be used to maintain the acoustic energy in a room and at the same time can treat unwanted echoes and reflections by scattering sound waves in many directions. The design allows for creating different interior space designs by changing the arrangement of the diffuser panels, and this leads to different applications for the diffusers.

Abstract: The present invention reduces corrosion rates on metal surfaces, such as the interior surfaces of gas flow control components by depositing a chemically inert layer on the metal surface of the component and other associated parts of the component that are exposed to corrosive gases. The disclosed method provides for depositing a relatively chemically inert thin film such as silicon dioxide along the gas exposed surface areas of the metal surface thereby enhancing corrosion protection to the metal surfaces. The present invention can be used to deposit a chemically inert thin film at locations inside components that are outside a direct line of sight and at locations normally unreachable by a gas flowing through the components. The present invention does not require a vacuum system for the deposition of the corrosion-resistant thin film.

Abstract: A system for measuring the thermal characteristic of the surface-lattice of solid state materials with picosecond time resolution uses a picosecond laser pulse which is synchronized with a picosecond electron pulse; the electron pulse being generated by splitting the laser pulse into two beams one of which interacts with the surface under test and the second activates the cathode of an electron gun creating an electron pulse which is, collimated, focused and incident at a small acute angle (1-3 degrees) on the surface. The electron pulse generates a reflection high energy electron diffraction pattern (RHEED) which provides information on the surface temperature in accordance with the Debye-Waller effect. Time resolved measurements are made by using electron pulses which are delayed with respect to the laser pulses by successively greater time intervals.
