Patent CA-3039866-A1 (CA)
Inventor: CARNIATO MICHAEL
IPC: B65G15/64
Filed: 2019-04-09
Abstract: A system for correcting transverse misalignment of a conveyor belt relative to a supporting pulley, includes a frame is pivotally attached to a stationary member. A guide surface engages the frame to guide pivoting of the frame about the pivot point simultaneously about a vertical axis and a longitudinally aligned axis. Idler rollers rotatably mounted on the frame define a rolling contact surface for the conveyor belt, which is concavely-shaped in a transversely-extending vertical plane. The pivoting of the frame causes the surface to impart a combined transverse pushing effect, torsional steering effect, and torsional tiling effect on the conveyor belt. An actuator applies a force to pivot the frame about the axis. A  computer determines an amount of the misalignment based on a signal from a sensor, and automatically controls the actuator to pivot the frame, depending on the determined amount of the misalignment.

Title: System and method for demodulating code shift keying data utilizing correlations with combinational prn codes generated for different bit positions
Inventor: BROWN DAVID
IPC: H04L27/22
Filed: 2019-06-28
Abstract: A global navigation satellite system (gnss) receiver demodulates code shift keying (csk) data utilizing correlations with combinational pseudo-random noise (prn) codes generated for different bit positions. The gnss receiver receives a signal including a prn code modulated by csk to represent a symbol (i.e., csk modulated symbol). The gnss receiver maintains a plurality of receiver codes, each representing a different shift in chips to the prn code. The gnss receiver performs a chip-by-chip linear combination of a group of receiver codes for each bit position of the csk modulated symbol.  The gnss receiver correlates the received signal with each combinational prn code to produce a binary value that is the csk modulated symbol.
