Abstract: A tilt-up door having vertical side members each having a pivot point, the pivot points move upward or downward when an actuator is activated to move the door between open and closed positions. First and second cams connected to the vertical side members at a lower end of the cams, each of said cams extend from the lower end thereof upwardly and arcuately toward an interior of a building to a distal terminal end thereof, each of the ends contacts a cam follower. The cam followers slide along the first and second cams and guide the first and second cams and the door as the door moves between the open and closed positions.

Abstract: A mobile ticketing method and system for providing mobile ticketing services to users is provided. A user selects a mobile ticket and initiates payment by using a user device. In response to successful processing of the payment, the user device receives encrypted QR data from a server. The user device decrypts and format the encrypted QR data to display a QR code. The QR code is scanned at a gate terminal associated with an entry or exit gate. The gate terminal validates the QR code and broadcasts data pertaining to the QR code via a BLE network. The user device verifies the gate terminal on receiving the broadcasted data via the BLE network, and transmits a connection request to the gate terminal. The gate terminal further validates the connection request and decides whether to allow or disallow the user to pass through the entry or exit gate.
