Patent number: 11330410Abstract: Pathside communication relay (PCR) for collecting and distributing pathside data among client devices. The PCR collects client data from client devices (such as vehicles, pedestrians, and roadside infrastructure) and sensor data from sensors. The PCR processes the collected client data and sensor data and generates pathside data to be distributed among the client devices. In some examples, the PCR includes wireless telecommunication circuitry for distributing the pathside data over dedicated short-range communications (DSRC) signals using the Wireless Access in Vehicular Environments (WAVE) protocol and/or Cellular-Vehicle to everything (Cellular-V2X) communications. The pathside data can include location data of client devices and other objects, ambient conditions, traffic data, and other information to facilitate improved decision-making (such as collision avoidance) by client devices.Type: GrantFiled: January 31, 2019Date of Patent: May 10, 2022Assignee: Corning Research & Development CorporationInventors: Santanu Basu, Donnell Thaddeus Walton

Publication number: 20190304296Abstract: Pathside communication relay (PCR) for distributing network data among client devices. The PCR receives network data from a PCR network, which may include other PCRs and a central unit. The network data is processed (e.g., to determine a relevant portion for one or more client devices connected to the PCR), and at least a portion of the network data is transmitted within a communication coverage area. In some examples, the PCR includes wireless telecommunication circuitry for distributing the network data over dedicated short-range communications (DSRC) signals using the Wireless Access in Vehicular Environments (WAVE) protocol. The network data can include pathside data from other PCRs in the PCR network and other information, such as location data of client devices and other objects, ambient conditions, traffic data, and other information to facilitate improved decision-making (such as collision avoidance) by client devices.Type: ApplicationFiled: January 31, 2019Publication date: October 3, 2019Inventors: Santanu Basu, Donnell Thaddeus Walton

Patent number: 8878746Abstract: A multi-screen electronic device includes a first electronic device having a first electronic device screen and a second electronic device having a second electronic device screen. The first and second electronic device screens are stacked and on different planes when the multi-screen electronic device is in a compact form. The first and second electronic device screens are unstacked and on the same plane when the multi-screen electronic device is in an expanded form. A translation mechanism is coupled to the first and second electronic devices. The translation mechanism is configured to guide a motion of at least one of the first and second electronic devices along a nonlinear path such that a travel along the nonlinear path in a forward direction transforms the multi-screen electronic device from the compact form to the expanded form and a travel along the nonlinear path in a reverse direction transforms the multi-screen electronic device from the expanded form to the compact form.Type: GrantFiled: February 23, 2011Date of Patent: November 4, 2014Assignee: Corning IncorporatedInventors: William Edward Lock, Donnell Thaddeus Walton, Kevin Lee Wasson, Todd Marshall Wetherill
