Abstract: Aspects of the present disclosure are directed toward devices, apparatus, and methods for interfacing a PPG apparatus with the skin surface of a patient and sensing artifacts due to surface motion attributable to contact-based surface motion at or near where the apparatus in contact with the skin surface of the patient. The devices, apparatus, and methods include circuitry that contacts the skin surface of the patient, illuminates tissue at the surface, and senses a pulse photoplethysmography (PPG) signal of the patient in response thereto. Further, the circuitry senses artifacts due to surface motion, and responds to the sensed PPG signal by processing the sensed PPG signal relative to the sensed artifacts to produce a version of the sensed PPG signal that is indicative local blood volume and composition of the patient, and filtered to suppress noise therein due to the contact-based surface motion.

Abstract: A device is disclosed for therapeutic and/or diagnostic use in or on a patient's body. The device can have a sheath and a tool. The sheath can be made, at least in part, from a laminate. The laminate can have reinforcement fibers in longitudinal, latitudinal, helical, and/or other configurations around the sheath. The tool can be at least partially within the sheath.

Abstract: Physiological monitoring can be provided through a wearable monitor that includes two components, a flexible extended wear electrode patch and a removable reusable monitor recorder. The wearable monitor sits centrally on the patient's chest along the sternum oriented top-to-bottom. The placement of the wearable monitor in a location at the sternal midline (or immediately to either side of the sternum) benefits extended wear by removing the requirement that ECG electrodes be continually placed in the same spots on the skin throughout the monitoring period. The wearable monitor can interoperate wirelessly with other physiology and activity sensors and mobile devices, and can include cellular phone capabilities. The power usage of the wireless communication can be reduced by using a low energy wireless transceiver in the monitor. The monitor detects that the monitor has been adhered to the patient and begin collecting physiological data after such detection, preserving battery power.

Abstract: Methods to identify and risk stratify disease states, cardiac structural defects, functional cardiac deficiencies induced by teratogens and other toxic agents, pathological substrates, conduction delays and defects, and ejection fraction using single channel biological data obtained from the subject. A modified Matching Pursuit (MP) algorithm may be used to find a noiseless model of the data that is sparse and does not assume periodicity of the signal. After the model is derived, various metrics and subspaces are extracted to characterize the cardiac system. In another method, space-time domain is divided into a number of regions (which is largely determined by the signal length), the density of the signal is computed in each region and input to a learning algorithm to associate them to the desired cardiac dysfunction indicator target.

The outputs from the sensors are used to distinguish between new and prior occupants of the support apparatus, automatically zero an integrated scale system, distinguish between objects and humans on the support apparatus, determine if a person is sleeping or awake, monitor and characterize movement levels of the person, record a log of likely events regarding a support surface of the apparatus, propose identifications of objects added to or removed from the support surface, record force outputs, and/or other purposes. A person's sleep state may also be obtained and forwarded to a remote location. The sleep state data may be used to mute and/or control alerts or indicators, and/or to predict when a person is going to wake up and likely exit the support apparatus.

Abstract: A system and method of illuminating tissue, particularly within the cranial cavity, through the mouth or nose. The system includes a light source and a power source for powering the light source. Optics are included for directing light from the light source towards the cranial cavity when the apparatus is inserted into a cavity of the head. Light from the light source and output from the optic provides cellular interaction treatment toward a specified area of the head region. Providing illumination where there are already holes in the skull results in more efficient coupling of light to the cells.
