The present invention relates to methods of fitting for pre-fabricated compression garments via digital imaging of a wearer body part and measurement of body part circumferences and, optionally, lengths therefrom. The present invention also relates to methods of generating a shape description derived from digital imaging of a patient body part or body area of interest and use of such shape description. Such shape description includes geometric information from which measurement information can optionally be derived. Included herein are methods for diagnosing and monitoring edema and other conditions in patients using shape descriptions acquired from a patient in need of such diagnosis and monitoring. The invention also includes use of the generated shape descriptions to make compression garments specifically configured for a patient's body part or body area. Compression garments generated from the generated shape descriptions are also included herein.

A monitoring device configured to be attached to a body of a subject includes a sensor having at least one optical emitter and at least one optical detector, and a processor coupled to the sensor. The processor is configured to instruct the at least one optical emitter to emit a different wavelength of light into the body of the subject during each of a series of respective time intervals. The processor is configured to measure a respective different physiological parameter from signals produced by the at least one optical detector upon receiving light from the body of the subject during each of the respective time intervals.

A monitoring device configured to be attached to a subject includes a photoplethysmography (PPG) sensor configured to measure physiological information from the subject, and at least one processor configured to process signals from the PPG sensor to determine heart rate and RR-interval (RRi) for the subject, and to determine a heart rate pattern for the subject over a period of time. The at least one processor is configured to change a sampling frequency of the PPG sensor for determining RRi in response to the determined heart rate pattern. The at least one processor is configured to reduce the sampling frequency of the PPG sensor in response to determining a pattern of heart rate below a threshold.

A monitoring device configured to be attached to a subject includes a photoplethysmography (PPG) sensor configured to measure physiological information from the subject, a blood flow stimulator, and a processor configured to process signals from the PPG sensor to determine a confidence score of the signals. In response to a signal-to-noise level determination, the processor is configured to instruct the blood flow stimulator to increase blood perfusion at a location where the PPG sensor is attached to the subject. The confidence score is an indication of how strongly the signals can be trusted.

A monitoring device configured to be attached to a subject includes a photoplethysmography (PPG) sensor configured to detect/measure physiological information from the subject, and a processor configured to process the physiological information to detect subject stress, and to determine an origin of the subject stress. The processor can determine the origin of the subject stress by increasing a sampling rate of the PPG sensor to collect higher acuity physiological information. The processor also can determine the origin of the subject stress by processing data from the PPG sensor to determine whether the subject is likely to have atrial fibrillation. In response to determining that the subject is likely to have atrial fibrillation, the processor can increase a frequency of pulsing of an optical emitter of the PPG sensor and/or increase a sampling rate of the PPG sensor to collect higher acuity data for diagnosing that atrial fibrillation is truly occurring.

Disclosed is a method of controlling operation of a medical device that regulates delivery of a fluid medication to a user. The method receives meter-generated values that are indicative of a physiological characteristic of the user, and are produced in response to operation of an analyte meter device. The method obtains sensor-generated values that are indicative of the physiological characteristic of the user, and are produced in response to operation of a continuous analyte sensor device, different than the analyte meter device. The medical device is operated in different modes when: a valid meter-generated value is available; a valid meter-generated value is unavailable and a current sensor-generated value satisfies first quality criteria; or a valid meter-generated value is unavailable and the current sensor-generated value satisfies second quality criteria but does not satisfy the first quality criteria.

A monitoring device configured to be attached to a subject includes a sensor configured to detect and/or measure physiological information and a processor coupled to the sensor. The sensor includes at least one optical emitter and at least one optical detector. The processor receives and analyzes signals produced by the sensor, and the processor changes wavelength of light emitted by the at least one optical emitter in response to detecting a change in subject activity. For example, the processor instructs the at least one optical emitter to emit shorter wavelength light in response to detecting an increase in subject activity, and the processor instructs the at least one optical emitter to emit longer wavelength light in response to detecting an decrease in subject activity. Detecting a change in subject activity may include detecting a change in at least one subject vital sign and/or subject motion.

The present disclosure provides systems for controlling movement of a table supporting an object. The system may include: a first control sub-system configured to generate a first control instruction; a second control sub-system configured to generate a second control instruction; a table control sub-system operably coupled to the table; and a master controller configured to receive the first control instruction from the first control sub-system, or the second control instruction from the second control sub-system, generate a third control instruction based on the first control instruction or the second control instruction, and transmit the third control instruction to the table control sub-system. The table control sub-system may be configured to generate a control signal based on the third control instruction, and cause the table to move based on the control signal.
