Latest Patents
Hatzirallis holds a patent for a hierarchical elevator control system that utilizes standard Control Area Network (CAN) hardware and message protocols. The patent describes a broadcast message format that includes priority bits and source address bits within the standard CAN message identifier field. This design separates priority levels from message type information while maintaining collision avoidance through the use of source addresses. Additionally, the unicast message format allows for message responses by individual receiving nodes using simple standard CAN hardware filtering. This is achieved by providing a multi-bit destination address field within the standard CAN message identifier field, which identifies a unique receiving node for directed messages.
