Patent number: 6137424Abstract: An automatic traffic monitoring system for enforcing traffic laws and regulations and for general purpose traffic monitoring includes a novel passive road sensor that accurately detects the kinematics of moving vehicles. A passive road sensor includes a detector protected in an enclosure, which is embedded in a road opening, is in a continuous listening mode. When the wheels of a passing vehicle come in contact with either the road opening, the enclosure, or both, the resulting mechanical impact generates a disturbance that triggers the detector. A processor unit of the automatic traffic monitoring system records the signal sensed by the detector and analyzes its temporal characteristics to determine the precise time of impact.Type: GrantFiled: January 15, 1999Date of Patent: October 24, 2000Assignee: Tracon Sysytems, Ltd.Inventors: Simon S.

Patent number: 5191603Abstract: The invention provides a device to be connected to a telephone line and, alternatively, to a telephone set or a printer. The device comprises a switch device for automatically operating the one or the other connection according to the signals received through the line. When modulated telefax signals are received, they are transmitted to a modem which transforms the signals to sequential digital signals, these are stored in a buffer memory, at least to an extent corresponding to a line of print, and they are then transformed by a microcircuit to matrix digital signals, which are transferred to the printer. Fax messages transmitted through the telephone line are thus automatically printed out. The invention also provides a printer, which incorporates a modem, a buffer memory and microcircuit for performing the aforesaid operations, through which the printer may selectively be connected to a telephone line, and which may be by-passed to connect the printer to a computer.Type: GrantFiled: January 16, 1991Date of Patent: March 2, 1993Inventor: Oded Kafri

Patent number: 4854708Abstract: Optical examination apparatus is described including a basic setup comprising a point source of light, a first optical system forming a converging beam of light reflected from the examined object, and a second optical system located to receive the intercepted beam of reflected light, to collimate it, and to direct the collimated beam to a viewing device. The basic setup is capable of combined operation as a Fizeau interferometer, a schlieren device, and/or a moire deflectometer.Type: GrantFiled: November 23, 1987Date of Patent: August 8, 1989Assignee: Rotlex Optics Ltd.Inventors: Oded Kafri, Kathi M.

Patent number: 4810895Abstract: A method and apparatus for moire ray deflection mapping for determining properties of an object in which a point source of light producing a diverging beam of direct light is passed through a first optical system including the object to be examined, which system retraces the light in the form of a converging beam of reflected light from the examined object back towards the point source. The converging beam of reflected light is intercepted before reaching the point source and is passed through a second optical system which collimates the beam of reflected light. The collimated beam is then directed through first and second gratings at a preselected angular orientation with respect to each other to produce moire fringe patterns providing an indication of the properties of the examined object. An important advantage in the above novel method is that the same setup can be used for measurements of both phase objects and specular surfaces.Type: GrantFiled: February 8, 1988Date of Patent: March 7, 1989Assignee: Rotlex Optics Ltd.Inventors: Oded Kafri, Ilana Glatt
