A system and method for noninvasively measuring blood pressure is disclosed. In one embodiment, the system includes a monitoring cuff comprising at least one sensor implanted within the monitoring cuff, the at least one sensor being configured to detect blood flow data in a user, an occlusion cuff configured to inflate and deflate to restrict and permit blood flow in the user, the occlusion cuff being in electrical communication with the monitoring cuff, and a computing device configured to control the inflation, deflation, and pressure applied by the occlusion cuff, and the computing device being configured to record and analyze the blood flow data detected by the monitoring cuff.

The disclosure provides wearable cardiac arrest detection and alerting device that incorporates a non-invasive sensor based on optical and/or electrical signals transmitted into and received from human tissue containing blood vessels, and that transcutaneously quantifies the wearer's heart rate. The heart-rate quantification enables the detection of the absence of any heart beat by the wearable detection and alerting device indicative of the occurrence of a cardiac arrest, wherein the heart is no longer achieving effective blood circulation in the individual wearing the device. The display on the wearable cardiac arrest detection and alerting device may include the elapsed time since the time of detection of a heart rate that is below a predetermine lower limit value, i.e., the detected occurrence of a cardiac arrest event.

Ultrasonic energy is used for treating degenerative dementia. A focal point of an ultrasonic transducer beam is directed at a target area of the brain to promote removal of substances that accumulate in the interstitial pathways that are at least partially responsible for the degenerative dementia. In one example, the target area of the brain may comprise the hippocampus and the degenerative dementia may be Alzheimer's disease. The ultrasonic beam may stimulate brain tissue at a frequency that corresponds to a naturally occurring deep sleep burst frequency of neurons and subsequent astrocyte activation patterns that drive a convective process responsible for brain solute disposal. For example, the transducer may generate a burst frequency of between 1-4 hertz to stimulate deep sleep brain functions that help remove amyloid plaque.

A bladder volume detection device, the device comprising a sound transmitter and at least one receiver the device configured to ping the bladder with an acoustic signal having a resonant frequency of up to about 20 k Hz generated with said transmitter.

Systems and method for destroying or inhibiting cancer cells and other rapidly-dividing cells include applying AP magnetic fields having a defined frequency of 5 Hz-500 kHz and a field strength of 0.1-5000 μT to a target body area that includes the cancer or other rapidly-dividing cells, and modifying the cancer or tumor microenvironment to increase the presence of cancer-suppressive cells or decrease the presence of cancer-promoting cells. In various embodiments, the systems and methods may include adjusting the therapy based on ultrasound imaging of the cancer cells during the application of the AP magnetic fields or during a cessation of applying the AP magnetic fields.

The invention relates to a method for controlling an ultrasound system comprising at least two ultrasound sensor units using gestures. The method comprises: detecting a gesture on a first ultrasound sensor unit; matching the detected gesture to one of the plurality of gestures in the gestures database; reading the assigned at least one system function in the gesture database related to the detected gesture; and activating the at least one system function. At least one system function includes switching a sound source from a second ultrasound sensor unit to said first ultrasound sensor unit and wherein the gesture assigned to this system function comprises a double-tap on the surface of the first ultrasound sensor unit. Further, the invention relates to a system for carrying out the method.

A method for measuring dynamic movement of a joint, the method comprising the steps of: measuring relative rotation of the joint using pair of Inertia measurement units, each attached to the skin on either side of said joint; capturing a plurality ultrasound images of a bone proximate to a first of said IMU's; identifying markers on said bone; tracking displacement of the markers; correlating said displacement with the relative rotation of the joint, and so; measuring the dynamic movement of the joint.

A method and apparatus to non-invasively measure instantaneous blood pressure using pulse wave velocity are disclosed. A measurement component is affixed to a patient proximate to a blood vessel. One or more sensors, such as an ultrasound sensor, is included in the measurement component. The measurement component substantially simultaneously measures the pulse wave velocity of the vessel and the instantaneous blood velocity within the vessel. The measurement component computes the instantaneous blood pressure of the vessel using, for example, the water hammer equation. The one or more sensors may be contained in a disposable patch or collocated with another sensor, such as a patient-monitor sensor, or the like.

Devices, systems and/or methods for monitoring and/or stimulating osteogenesis use sensor data from a target site of a bone to produce a quantitative output that can be used to determine the healing rate of the patient, when the bone at the target has fully consolidated and/or to direct further treatment of the patient.
