Abstract: A network discovery method includes: sending, by a master node in a logical root hierarchy level of a data network, a discovery message including a forwarding counter to a first slave node in the data network first logical hierarchy level via a child port; increasing, by the first neighboring slave node, the forwarding counter; forwarding the discovery message with the increased forwarding counter to a second slave node in the first logical hierarchy level; receiving, by the first and second slave nodes, context information from the master node regarding the identities of the master node and the child port; determining, by the first and second slave nodes, its own functional designation based on the forwarding counter and the received context information by comparison with a mapping table; and updating the mapping table by matching the recorded functional designation in the mapping table with the first and slave node identities.

Abstract: Systems, devices and methods for draining and analyzing bodily fluids, pressures and assessing health are described where a drainage system generally comprises an elongate catheter having a first end and at least one opening in fluid communication with a catheter lumen, a drainage tube having a drainage lumen in fluid communication with a second end of the catheter, a fluid reservoir in fluid communication with the drainage lumen, and a pressure sensing membrane in communication with a pressure lumen defined through the catheter. The system also includes a pressure sensor coupled to the pressure lumen and configured to receive an intra-abdominal pressure signal from the pressure sensing membrane via the pressure lumen, and a controller in communication with the fluid reservoir and the pressure sensor. The controller is configured to determine an abdominal perfusion pressure based on the intra-abdominal pressure and a mean arterial pressure received by the controller.

Abstract: A method of cutting a microtrench in which the buried utility is exposed by opening an access hole in a roadway above the buried utility using a roadway access hole drill that rotates and vibrates the drill bit. A roadway access hole drill having a down-the-hole jack-hammer drill bit and a motor to rotate the down-the-hole jack-hammer drill.

Abstract: A microtrencher having a vacuum system configured to clean spoil from a microtrench having a rotating brush. A method of using the microtrencher to cut a microtrench in a roadway and using the vacuum system to clean spoil from the roadway and microtrench.

Abstract: A cell and/or internet device that can be connected to existing city devices that are powered by city power to install a wireless cell and/or internet service to the city. The system has a plurality of the cell and/or internet devices connected to associated city devices powered by city power, and the cell and/or internet devices are controlled by a server. A method of using the system to provide cell and/or internet services to a city.

Abstract: Provided is a microtrencher having a utility avoidance system that detects objects buried under the roadway, identifies whether the buried object is a utility and determines whether the buried utility is in the path of the cutting wheel. If the buried utility is in the path of the cutting wheel, an alert is sent to the operator, the vehicle is stopped, and/or the cutting wheel is raised in relation to the roadway. Also provided is a method of using the microtrencher to cut a microtrench in a roadway and to avoid cutting a buried utility in the path of the cutting wheel.
