Patent number: 10487565Abstract: A detecting system for an automatic door is provided including a TOF camera having a field of view that is limited in a first zone for a first purpose such as safety and in a second zone for another purpose such as activation or counting. The proposed system can be used for example in powered pedestrian doors, bus, rail, etc. In some embodiments, at least one ultrasound sensor system is further provided. The two technologies share hardware and information, resulting in improved safety and counting functions of the system, while reducing the amount of hardware used, space requirement and unit cost, and improving performance.Type: GrantFiled: March 28, 2019Date of Patent: November 26, 2019Assignee: SENSOTECH INC.Inventors: Uri Agam, Pino Marcovecchio

Patent number: 8875441Abstract: Embodiments of an adaptive ultrasound detecting system for a door assembly include an ultrasound transducer assembly mounted to the door assembly and a controller coupled to the ultrasound transducer assembly. The ultrasound transducer assembly is adapted to emit ultrasound detecting beams within the door path, and to trigger a detecting signal indicative of a body located within the door path when the body intersects at least one of the ultrasound detecting beams. The controller is adapted to receive information indicative of a position of the door along the path, and to vary emitting at least one detecting beam in accordance to the position of the door relative to the ultrasound detecting beams.Type: GrantFiled: May 31, 2013Date of Patent: November 4, 2014Assignee: Sensotech Inc.Inventors: Uri Agam, Pino Marcovecchio

Patent number: 8510990Abstract: A presence detector for a door assembly which includes a door closing a door entrance is described herein. The detector includes a transducer assembly mounted to the door assembly for emitting at least one ultrasound detecting beam adjacent the door entrance and for triggering a detecting signal indicative of a body located adjacent the door entrance when the body intersects the at least one ultrasound detecting beam and a controller for receiving information indicative of a position of the door and for controlling the emission of the at least one detecting beam accordingly with the position of the door. The detector assembly operates in crossing, ranging or dual modes.Type: GrantFiled: February 26, 2009Date of Patent: August 20, 2013Assignee: Sensotech Inc.Inventors: Uri Agam, Pino Marcovecchio

Patent number: 8353321Abstract: A system and method for short-range ultrasonic detecting of a target is proposed herein to be used for example in a liquid-dispensing system such as those provided in home refrigerators. The system comprises a sensor assembly including a transmitter and a receiver positioned side by side so as to yield respective transmitting and receiving beams which overlap to define an asymmetrical shaped detection area, a controller coupled to both the transmitter and receiver to activate the transmitter and for receiving echoes indicative of the target from the receiver and to the dispensing system for opening a valve of the dispensing system when a target is detected. Noises and false alarm rate minimization methods are implemented, including variable relevance zones and requiring a void of signal before excitation.Type: GrantFiled: April 6, 2007Date of Patent: January 15, 2013Assignee: Sensotech Inc.Inventors: Uri Agam, Eli Gal, Pino Marcovecchio

Patent number: 7715276Abstract: A presence detection system for level crossing or to detect a target at the intersection of any paths is described herein. The system comprises an ultrasound sensor array positioned at the intersection of the first and second paths for defining a detecting area thereon and for emitting a first trigger signal when the body is in the detecting area; and a controller coupled to the ultrasound sensor array for receiving the first trigger signal and for emitting an alarm signal indicative of the first trigger signal. The sensor array detects the presence of a target by creating acoustic virtual lines which form between emitter and receiver or transducer and reflectors and/or by deploying conical or parallel detecting beams and which can be used, for example to measure the distance between each sensor forming the array and the target. The sensor array can deploy beams or acoustic lines in several plans and therefore allow detecting penetration above the conventional railway crossing barriers.Type: GrantFiled: May 8, 2007Date of Patent: May 11, 2010Assignee: Sensotech Inc.Inventors: Uri Agam, Eli Gal, Pino Marcovecchio

The proposed system eliminates the phenomenon of oscillation (decay time of the excitation signal) between the incoming and outgoing sound waves. Noises and false alarm rate minimization methods are implemented, including variable relevance zones and requiring a void of signal before excitation.Type: ApplicationFiled: April 6, 2007Publication date: November 29, 2007Applicant: SENSOTECH, INC.Inventors: Uri Agam, Eli Gal, Pino Marcovecchio
