Abstract: A technical problem faced when remotely controlling or debugging electronic devices is that remote control or debugging often requires a direct connection. However, debugging ports are inaccessible on many devices. Technical solutions described herein provide systems and methods for secure communication via existing communication infrastructure (e.g., public instant messenger (IM)), providing various debugging abilities including debugging and file sharing. Technical solutions described herein also provide systems and methods for debugging based on remote device memory state collection and sending for embedded or IoT devices. This solution avoids a hardware debugging connection by using a debugging methodology resident on the device to read and dump the relevant memory, registers, and other device state information in a secure and automated manner.

Abstract: An apparatus for communicating information over a pressurized fluid-carrying pipe connecting a plurality of serial nodes. A sounder node (i.e., transmitter) creates variable pressure patterns within the fluid-carrying pipe, which pressure patterns are identified and detected by other nodes. The patterns convey information or solicit responses from the receiving nodes. The receiving nodes reply to the pressure fluctuations by inducing reply pressure fluctuations in the fluid-carrying pipe or by communicating with the sounder node via a separate radio frequency communications system. The apparatus and method can be used as an information-carrying communications medium or a train linking methodology for a railroad train.
