Abstract: A robotic system is proposed whereby the system comprises drivers which integrate the power switches and communications electronics for communicating over power lines or wirelessly or over another shared communications channel. In a robotic system comprising such drivers, one or more central controllers communicate with at least one actuator driver across a communications channel, wherein the communications channel is subject to interference caused by an actuator, and wherein at least one of the communication and the operation of the actuators is modified in anticipation of interference occurring such that reliable communication can be assured.

Abstract: Secure message transfer is provided in a network including at least a Home Area Network (HAN) having network devices A, B and C. The Home Area Network is capable to connect domains having different transmission formats and includes a secure communication protocol. Device A is capable to communicate at least one message to the device C according to the secure communication protocol, and device B is capable to receive at least one message from device A sent for reception and decryption by device C. A device D controls the secure message transfer and selectively disables device B from decrypting the message received by device B that is sent from device A to device C for decryption.
