Publication number: 20230371415Abstract: A perforator quick disconnect system for an aerator device includes a perforator and a retaining device. The perforator has a head with an exterior configured to be received within a mounting block of the aerator device and a female component that extends into the exterior of the head. The retaining device has a connector configured to connect to the mounting block and a male component disposed within the connector and moveable relative thereto from a first position to a second position. The female and male components together form a quick disconnect mechanism such that when the perforator and retaining device are received by the mounting block, the male component engages the female component when the male component is in the first position to connect the retaining device to the mounting block and disengages the female component when in the second position to disconnect the perforator from the mounting block.Type: ApplicationFiled: May 19, 2022Publication date: November 23, 2023Applicant: AmTech InternationalInventor: Von Davis

Patent number: 11323865Abstract: A system is described for tracking vehicle position using a smart phone or similar device as an active transponder that communicates with roadside equipment. The system may uses existing RF transceivers on the smart-phone, such as Bluetooth® LE or WiFi to periodically transmit an identifying message. Road-based equipment detects and locates the smart phone. In a further aspect, the smart phone is alerted by roadside beacons and responds with identification information. Transaction processing may be performed either on the smart phone or by roadside or back office equipment. The system may be used for automated roadway tolling and monitoring and also for access control. A coded card may be scanned by the smart card to enter identification for access control.Type: GrantFiled: July 2, 2020Date of Patent: May 3, 2022Assignee: Amtech Systems, LLCInventors: Kelly Gravelle, John Todd Elson, Greg Lantz, Michael Melville, Paul Hamel, Yousuf Kamal

Patent number: 11288464Abstract: A multi-protocol RFID interrogating system employs a synchronization technique (step-lock) for a backscatter RFID system that allows simultaneous operation of closely spaced interrogators. The multi-protocol RFID interrogating system can communicate with backscatter transponders having different output protocols and with active transponders including: Title 21 compliant RFID backscatter transponders; IT2000 RFID backscatter transponders that provide an extended mode capability beyond Title 21; EGOTM RFID backscatter transponders, SEGOTM RFID backscatter transponders; ATA, ISO, ANSI AAR compliant RFID backscatter transponders; and IAG compliant active technology transponders. The system implements a step-lock operation, whereby adjacent interrogators are synchronized to ensure that all downlinks operate within the same time frame and all uplinks operate within the same time frame, to eliminate downlink on uplink interference.Type: GrantFiled: August 3, 2020Date of Patent: March 29, 2022Assignee: Amtech Systems, LLCInventors: Kelly Gravelle, Steven J.

Patent number: 11039284Abstract: A system for tracking vehicle position using a smart phone in the vehicle as an active transponder, which is detected by roadside equipment is disclosed. In an embodiment, the system uses existing RF transceivers on the smart-phone, such as Bluetooth LE or WiFi to periodically transmit an identifying message. Road-based equipment detects and locates the smart phone. In a further embodiment, the smart phone is alerted by roadside beacons and only then responds with its identification information. Processing can be performed either on the smart phone or by roadside or central office equipment as is the case in prior art active or passive transponder-based tolling systems. Vehicle location detection can be enhanced through the use of directional antenna matrices such as a Butler matrix. The system can be used for automated roadway tolling and monitoring.Type: GrantFiled: March 2, 2016Date of Patent: June 15, 2021Assignee: Amtech Systems, LLCInventors: Kelly Gravelle, John Todd Elson, Greg Lantz, Michael Melville, Paul Hamel

Patent number: 10607044Abstract: A multi-mode, preferably dual mode, radio frequency identification (RFID) tag is adapted for automatic detection of whether a RFID reader located within communication range of the RFID tag is transmitting a continuous wave (CW) or modulated wave types of RF signal, and accordingly, mandating a response from the tag in read-only (RO) mode or read/write (R/W) mode, respectively. The tag includes means for designating one of the RO and R/W operating modes as a default mode of the tag, and for switching the tag from its default mode to its other operating mode, and vice versa, according to a rule for determining the frequency of occurrence of a selected event related to signal type of the reader. A device-implemented method of this automatic detection, and a method of fabricating the tag, are also disclosed.Type: GrantFiled: July 8, 2019Date of Patent: March 31, 2020Assignee: Amtech Systems, LLCInventors: Kelly Gravelle, Robert W.
