Abstract: An imaging system for continuous blood pressure monitoring including determining pulse transit time using ballistocardiography and photoplethysmography is provided. Images received from the imaging system are analyzed to identify heartbeat related micromovements and changes in blood volume at capture points of the body. One or more capture points may have a patch that amplifies heartbeat related movements of the patient's skin beneath the patch. Some patches may include transparent optical filters. Images may be analyzed to identify changes in blood volume at specific capture points on the body using transdermal optical imaging. The micromovements and blood volume may be used to calculate pulse transit time between one or more capture points on the body. Blood pressure may be calculated using the pulse transit time.

Abstract: Systems and methods for modifying power consumption of a wearable device are provided. The systems and methods include an imaging device, a directional antenna, and a power transmission device in combination with a wearable device. The imaging device, antenna, and power transmission device are positioned and re-positioned so that the wearable device is in the center of the field of view of at least one of the imaging device, antenna, and power transmission device. The systems allow for a decrease in the gain of the wearable device, decreasing power usage. The system may also allow for remote charging of the wearable device.

Abstract: This disclosure is directed toward systems and methods for monitoring patients in a clinical setting by using non-contact multimodal imaging. For example, based on receiving imaging data, a computing device may identify an object and a region of focus formed by the object. The computing device may then cause a sensor to capture first sensor data at a first time and second sensor data at a second time, wherein the sensor data is associated with the region of focus. Based on determining that a difference between the first sensor data and the second sensor data is greater than or equal to a threshold difference, the computing device may generate and send, to an additional computing device, an alert indicative of the second sensor data.
