Systems and methods for smoothing automated lane change (ALC) operations. A mission planner, upon receipt of an ALC request, sends a ALC heads up signal to a lateral control.

In some examples, a device displays a configuration user interface that comprises a prompt to select a number of cycles of a breathing sequence, adjusts the number of cycles of the breathing sequence to the selected number of cycles in response to selection, and initiates a breathing phase of the breathing sequence. In some examples, the device displays and fluctuates a progress indicator in accordance with the selected number of cycles. In some examples, a device detects a time associated with a first breathing sequence, generates a prompting criteria based on a predetermined prompting frequency and the detected time, determines if the prompting criteria has been met, displays a prompt to initiate a second breathing sequence, wherein the prompt comprises a first affordance, and displays a second breathing sequence user interface in response to selection of the first affordance.

The invention relates to a needle delivery device comprising a device body; one or more skin pinching members attached to the device body, the skin pinching members being moveable to pinch a longitudinal fold of skin of a patient. The device also comprises a drive mechanism configured to drive a needle out of the device body and along a needle path into the longitudinal fold of skin pinched between the pinching members, and subsequently withdraw the needle, the needle path extending substantially parallel to the surface of the patient.

Disclosed are techniques and devices that are operable to receive one or a number of generalized parameters of an automated insulin delivery algorithm. An input of at least one generalized parameter corresponding to a user may be used to set one or more of the number of specific parameters of the automated insulin delivery algorithm based on the inputted at least one generalized parameter. Physiological condition data related to the user may be collected. The automated insulin delivery algorithm may determine a dosage of insulin to be delivered based on the collected physiological condition. Signals may be output to cause a liquid drug to be delivered to the user based on an output of the automated insulin delivery algorithm related to the determined dosage of insulin.

An extension cannula for use with a conventional ECMO return cannula is provided. The extension cannula includes a flexible conduit transitionable between a collapsed insertion state and an expanded deployed state when in communication with blood flow from an ECMO machine via the ECMO return cannula. The extension cannula may be positioned through a conventional ECMO return cannula such that the proximal end of the flexible conduit is disposed within and proximal to the end of the ECMO return cannula, while the distal end of the flexible conduit is disposed in a patient's thoracic aorta to deliver oxygenated blood directly to the patient's thoracic aorta via one or more pores at the distal region of the flexible conduit to improve cerebral oxygenation, maintain systemic arterial pulsatility, and reduce the potential for end-organ injury.

Expanded, nanofiber structures comprising electrospun nanofibers, a plurality of holes, and, optionally, cells are provided. Methods of making the nanofiber structures as well as methods of use thereof, particularly for wound healing, are also provided.
US11738115B2
Compositions comprising translucent, dehydrated placental tissue and methods of preparing and using those tissues are provided. Repeated dehydration techniques may produce translucent, dehydrated placental tissues, including translucent, dehydrated placental membrane and umbilical cord, with improved visualization and/or handling characteristics. The present invention also includes methods of healing a wound of the skin, eye, nerve, tendon, muscle, dental region, or dura, including burns, comprising applying the translucent, dehydrated placental tissues of the invention to the wound.
US11738087B2
The present invention relates to compounds and their uses, in particular, compounds in the form of prodrugs that pro mote transport of a pharmaceutical agent to the lymphatic system and subsequently enhance release of the parent drug.
