Systems and methods for trenchless placement of an underground protective network of intertwined cables for protecting buried assets from accidental damage are disclosed. The system includes an apparatus for towing behind a vehicle and laying a plurality of continuous cables directly underground and interweaving the cables to form a cable network. The apparatus includes a plurality of soil rippers mounted at respective radial positions to a rotating carrier. The rotating carrier rotates about an axis that is at least partially normal to the ground surface. The rippers plow through the ground in the direction of vehicle travel and include a cable-feeding guide for directly and continuously feeding cable out underground during operation. In operation, the combined movement of the soil rippers from rotating the carrier and movement in the direction of travel serves to intertwine the cables deposited by respective rippers forming the protective network of intertwined cables.

The subject matter presented herein provides an efficacious system and method for diagnosing orthostatic intolerance and for treating orthostatic hypotension. A dynamic compression garment that comprises a servo-controlled splanchnic venous compression with automated binder system is used to regulate blood flow, for instance, during orthostasis. The system includes a programmable controller and a computing device in communication with the controller, an inflator, one or more sensors, and a power supply. The system can collect a user's biometric data, which may be transmitted to the user, a physician in charge of the user, or a third-party. Moreover, the biometric data may be incorporated into a machine learning model that can be used to further program the controller.

A fabric-based item may be provide with a stretchable band. The stretchable band may be formed from a ring-shaped strip of stretchable fabric having an opening configured to fit around a body part of a user. Circuitry may be coupled to strands of material in the stretchable band. The circuitry may include sensor circuitry for making measurements on the body part such as electrocardiogram measurements, blood pressure measurements, and respiration rate measurements. Wireless communications circuitry in the fabric-based item may be used to communicate wirelessly with external electronic equipment. A wireless power transmitting device may transmit wireless power. A coil formed from conductive strands in the fabric-based item may be used by wireless power receiving circuitry in the fabric-based item to receive the wireless power. The coil may have one or more turns that run around the ring-shaped strip of stretchable fabric.

A stretchable fabric signal path may include a conductive strand located between first and second outer fabric layers. The outer fabric layers may be formed from intertwined strands of elastic material. The conductive strand may have a wavy shape to accommodate stretching of the stretchable fabric signal path. First and second inner fabric layers may be located between the outer stretchable fabric layers. The inner fabric layers may be formed from intertwined strands of non-elastic material. The inner fabric layers may have strands that are intertwined with the outer fabric layers to serve as anchor points for maintaining the shape of the conductive strand as the stretchable fabric signal path expands and contracts. The outer fabric layers and inner fabric layers may be woven. The conductive strand may convey electrical signals such as audio signals, power signals, data signals, or other suitable signals.
