Abstract: Techniques for controlling a process to prevent injury are presented. The techniques include obtaining a location estimation of a mobile transmitter affixed to an object, where the location estimation is relative to a location of a fixed receiver, and where the obtaining the location estimation includes sending an ultra wideband communication from the mobile transmitter to the fixed receiver and acquiring the ultra wideband communication by a phased antenna array of the fixed receiver; assessing, based on the location estimation, that the mobile transmitter is within an impermissible location; determining that the location estimation is sufficiently accurate based on a distance between the location estimation and the fixed receiver; and interrupting the process upon both assessing that the mobile transmitter is within an impermissible location and determining that the location estimation is sufficiently accurate.

Abstract: Structures for a junction field-effect transistor and methods of forming a structure for a junction field-effect transistor. The structure comprises a first gate on a top surface of a semiconductor substrate, a second gate beneath the top surface of the semiconductor substrate, and a channel region in the semiconductor substrate. The first gate is positioned between a source and a drain, and the channel region positioned between the first gate and the second gate.

Abstract: A reservoir and method for manufacturing a method may be provided, the reservoir may include a first side piece, a second side piece, an inner fold piece and a reservoir fitting. The first side piece may be sealed to the second side piece with a top seal and a first side seal and a second side seal. The inner fold piece may be sealed to the first side piece and the second side piece through the first side seal, the second side seal, and a bottom seal. The top seal may include a fitting opening and the reservoir fitting may be fit into the fitting opening. The reservoir may contain a volume sensing system. The reservoir may be designed to shape and form to be optimized anatomically so as is to empty and fill reliably without any concern for neighboring organ impingement or compression.

Abstract: Systems and methods include the following. Information about a first electronic communication device is transmitted to at least one server and/or decentralized infrastructure. The information includes vicinity information. A status signal associated with a first user of the first electronic communication device is optionally transmitted. Contact proximity network information about a contact proximity network is received. The contact proximity network is based on the information from a plurality of electronic communication devices and information about the association between users and electronic communication devices. The contact proximity network information includes status signal information and interconnected nodes corresponding to different users and pairwise connections between users based upon their relative physical space and time proximity.

Abstract: A method for remotely bonding a companion device to an implanted medical device to achieve long-term encrypted and authenticated communication channel, that is resilient to companion device failure or compromise and hence mitigates the risk or need for unplanned, revision surgery and/or premature device explanation. Through use of a shared cryptographic key between the two systems, the companion device may request an encrypted challenge number from the implant. Completing the challenge via transmitting an encrypted validation number permits the implanted medical device to bond and perform a new long-term key exchange. The shared cryptographic key can be changed as well, in event of compromise or other adverse event, using a described device firmware update procedure.

Abstract: A bidirectional electroosmotic pump may be provided. The bidirectional electroosmotic pump may be made of materials that are biocompatible and non-ferrous. The bidirectional electroosmotic pump may be part of an implantable medical device for the purpose of medicine delivery. The bidirectional electroosmotic pump may contain a working fluid and may facilitate the delivery of a separate payload fluid. In an exemplary embodiment, the bidirectional pump may contain bellows which may allow the pump to deliver the payload fluid through a series of valves and/or catheters. In another embodiment the bidirectional electroosmotic pump may contain a pump sensing mechanism to monitor the state of the pump.

Abstract: Embodiments of the present disclosure provide a method for identifying those entities within a network that have the most influence on other entities within the network. A multi-relational network comprising links among a plurality of physicians is generated based on peer network data, wherein each link indicates a first physician that influences a second physician, and a weight of the influence. A decision by a treating physician of the plurality of physicians is decomposed, using a deep learning engine, into a magnitude of peer influence and a magnitude of control factor influence based on the multi-relational network and a plurality of control factors respectively. The magnitude of peer influence among one or more physicians in the multi-relational network is distributed among physicians in the multi-relational network based on the links each physician maintains with other physicians.

Abstract: A method for remotely updating the behavior and state of a medical device or the firmware itself of a medical device, not requiring physical access to the device, that occurs through an encrypted and authenticated communication channel. The behavior and state of the device may be modified from a healthcare provider interface through a transmission method. The firmware of the medical device may be modified by the use of over the air device firmware updates, created from a designated secure machine called a build machine described herein. Both actions are transmitted to a server and then forwarded to a companion device and are particularly designed so that the server never stores sensitive cryptographic material in the event of server compromise. The companion device forwards the update to the medical device, which decrypts and validates the update or command before performing the change.
