Abstract: Systems, methods, and computer-readable media are provided for using and dispatching an autonomous delivery. A wireless communications network may receive a request to delivery one or more items to a site and also determine that the autonomous delivery vehicle is the closest in location to the site from a plurality of autonomous vehicles. Additionally, the wireless communications network may determine that the autonomous delivery vehicle has stored thereon, the one or more requested items. The autonomous delivery vehicle may then receive by way of a wireless communication network, the request to delivery one or more items to an infrastructure site. The autonomous delivery vehicle then uses the location of the site to autonomously deliver the one or more items.

Abstract: Systems, devices, and techniques are described for analyzing evoked compound action potentials (ECAP) signals to assess the effect of a delivered electrical stimulation signal. In one example, a system includes a stimulation generator configured to deliver a stimulation pulse to a patient, sensing circuitry configured to sense an evoked compound action potential (ECAP) signal evoked from the stimulation pulse, and processing circuitry. The processing circuitry may be configured to determine a maximum value of a derivative of the ECAP signal, determine a minimum value of the derivative of the ECAP signal, determine, based on the maximum value of the derivative and the minimum value of the derivative, a characteristic value of the ECAP signal, and determine, based on the characteristic value of the ECAP signal, at least one parameter value at least partially defining electrical stimulation therapy to be delivered to the patient.

Abstract: The present disclosure relates to techniques for abstraction of unstructured clinical trial health data. Particularly, aspects are directed to obtaining, by a data transformation system, an unstructured document that includes various types of content for a given event. The data transformation system converts the unstructured document from an original format into a standardized format. The data transformation system processes the unstructured document in the standardized format to identify template-mapped content data and processes the template-mapped content data to identify high-interest content data. The data transformation system generates a dictionary data structure comprising key-value pairs for each of the template-mapped content data and the high-interest content data. The data transformation system generates a structured document based on the dictionary data structure for each of the template-mapped content data and the high-interest content data.

Abstract: Systems, devices, and techniques are described for calibrating a medical device that senses ECAP signals from a patient's nerve tissue. For example a method includes: instructing, with processing circuitry, stimulation circuitry of a medical device to deliver, on stimulation electrodes of the medical device, an electrical stimulation signal having an amplitude substantially equal to zero to a patient; entering, with the processing circuitry subsequent to instructing the stimulation circuitry to deliver the electrical stimulation signal, a passive recharge state on stimulation electrode circuitry; and auto-zeroing, with the processing circuitry, inputs to an operational amplifier of sensing circuitry electrically coupled to sensing electrodes of the medical device while the stimulation electrode circuitry is in the passive recharge state.

Abstract: A system for providing therapy to a patient includes stimulation generation circuitry, sensing circuitry, and processing circuitry. The processing circuitry is configured to cause storage of a first voltage at a first terminal at a first calibration capacitor and storage of a second voltage at a second terminal at a second calibration capacitor. The processing circuitry is configured to switch out a first calibration switch to prevent the first voltage stored at the first calibration capacitor from changing and switch out a second calibration switch to prevent the second voltage stored at the second calibration capacitor from changing and determine, with the sensing circuitry, a sensing signal based on the first voltage offset by a first calibration voltage stored by the first capacitor and based on the second voltage offset by a second calibration voltage stored by the second capacitor.

Abstract: An example medical device includes a battery configured to provide power to the medical device and stimulation circuitry configured to generate an electrical stimulation signal. The medical device includes hibernation control circuitry configured to cause the medical device to enter a hibernation mode in response to a hibernation trigger and exit the hibernation mode in response to a wake-up trigger. The medical device includes a switch configured to open in response to the hibernation control circuitry causing the medical device to enter a hibernation mode and close in response to the hibernation control circuitry causing the medical device to exit the hibernation mode and isolation interface circuitry configured to prevent power leakage from the hibernation control circuitry to the stimulation circuitry when the medical device is in hibernation mode. The stimulation circuitry is not powered by the battery when the medical device is in the hibernation mode.

Abstract: A method of making a corrugated metal deck assembly including an elongated corrugated metal deck portion having substantially longitudinally extending, generally U-shaped peaks and valleys. One or more support channels are formed integrally with the corrugated metal deck portion prior to casting concrete thereon. Each of the support channels are configured with a generally U-shaped cross-section having generally opposed side walls having leg portions extending generally laterally inwardly from the corresponding side walls and defining a slot facing generally downwardly from the corrugated metal deck. The support channels are adapted for receiving therethrough and supportably engaging at least portions of anchors or support items. The slots may be provided with one or more internal threads into which externally threaded portions of anchors or support items may be screwed to fixedly attach the anchors or support items to the one or more integrated support channels.
