Publication number: 20240121584Abstract: A method of communication between first and second controllers positioned in spaced relation along a length of a vehicle system includes establishing first and second wireless, parallel communication channels between the first and second controllers. The channels operate at different carrier frequencies. The first controller transmits common information in parallel on the first and second wireless communication channels to the second controller, and the second controller receives the information transmitted in parallel on first and second wireless communication channels. The first and second wireless communication channels are then deactivated Subsequently, a single communication channel is established for communicating other, different information between the controllers.Type: ApplicationFiled: December 18, 2023Publication date: April 11, 2024Inventors: Padam Dhoj Swar, Carl L.

Patent number: 11932292Abstract: A system is provided that may include a first communication controller that may communicate with a vehicle system formed from two or more vehicles. The first communication controller may operate in different modes, including a first mode to control movement of the vehicle system without repeating any control signals communicated between the vehicles, and in a second mode to monitor different frequencies for receipt of the control signals, receive and repeat a first control signal of the control signals at a first frequency, and receive and repeats a second control signal of the control signals at a second frequency. The first communication controller may also operate in a third mode in which the first communication controller may monitor the first frequency but not the second frequency for the first control signal, receives the first control signal at the first frequency, and repeats the first control signal at the first frequency.Type: GrantFiled: December 14, 2021Date of Patent: March 19, 2024Assignee: TRANSPORTATION IP HOLDINGS, LLCInventors: Brian Kurz, Richard S.

Patent number: 11891030Abstract: A braking system conducts an electronic command signal via a cable extending through multiple first vehicles in a first segment of a multi-vehicle system. The electronic command signal directs engagement or release of an air brake coupled to a brake pipe that extends along a length of the multi-vehicle system. A pneumatic command signal is communicated via the brake pipe to one or more second vehicles in a second segment of the multi-vehicle system. The pneumatic command signal directs one or more of the engagement or the release of the air brake coupled to the brake pipe in the one or more second vehicles.Type: GrantFiled: September 8, 2021Date of Patent: February 6, 2024Assignee: WESTINGHOUSE AIR BRAKE TECHNOLOGIES CORPORATIONInventors: Charles L.

Patent number: 11818631Abstract: A communication device and method may include at least one tuner circuit that monitors at least a first frequency channel and a second frequency channel. A controller of the radio receiver may measure a first received signal strength indicator (RSSI) value over time for the first frequency channel and a second RSSI value over time for the second frequency channel. The first and second RSSI values are based on a signal strength of radio frequency (RF) energy received on the first and second frequency channels, respectively. The controller may detect a leader portion of a message on the first frequency channel responsive to a change in the first RSSI value exceeding a step change threshold. The controller may extract, via a detector circuit, message data from a carrier wave of the RF message.Type: GrantFiled: October 26, 2021Date of Patent: November 14, 2023Inventors: Carl L.
