  • Patent number: 11538157
    Abstract: A method for determining healing progress of a tissue disease state includes receiving a thermal image of a target wound area from a thermal imaging system, processing the thermal image to construct an isotherm map of at least one selected area, determining a thermal index value from the isotherm map, correlating the wound thermal index value with a reference thermal index value representative of an injury-free state.

  • Patent number: 11350872
    Abstract: A system for predicting an occurrence of a foot ulcer includes a mat configured to be stood upon by a human subject, a plurality of sensor arrays disposed on or in said mat and arranged in adjacent proximity to one another. Each sensor includes an oxygenation probe, itself including a first light source and a light detector, and a secondary probe operable to utilize the light detector of the oxygenation probe and itself including a plurality of light sources exclusive of the first light source. The plurality of light sources of the secondary probe are arranged in a pattern around the oxygenation probe. The oxygenation probe is located at the approximate geometric center of the pattern. The system further includes a control module in signal communication with the light detector, and configured to independently control emission of light from the first light source of the oxygenation probe and the plurality of light sources of the secondary probe.

  • Patent number: 10299736
    Abstract: Methods, devices, and systems according to present principles provide ways to diagnose frailty and assess the severity of its clinical status—e.g., non-frail, pre-frail, and frail, especially as measured and quantified during activities of daily living. Systems and methods according to present principles objectively quantify physical activity behaviors and identify specific motor tasks, which indicate clinical frailty syndrome behaviors such as flopping, cautious-sitting, non-uniform walking fluctuations, cognitive decline, slowness, weakness, and exhaustion. Additionally, the systems and methods allow improved sensitivity and specificity of frailty identification by further assessing physiological parameters such as heart rate, respiration rate, and skin temperature in response to, or recovery from, specific activities.

  • Publication number: 20180280696
    Abstract: A sensor interface device (e.g., orthotic device or immobilization device) is disclosed. More specifically, described is an individualized sensor device and system to prevent tissue damage resulting from, for example, pressure, torsion, temperature, shear, altered blood flow, reduced oxygen tension, pH levels, tissue conductivity, tissue viscoelasticity, infection and sweat chloride levels. In particular embodiments, the systems, devices and related methods are used for preventing ambulation and mobility related plantar tissue related damage and immobilizing tissues.

  • Patent number: 8105257
    Abstract: The present invention provides an extremity stress reducing modality for a human subject having an extremity, the extremity having an uninjured portion and an injured portion. The modality includes: (1) a frame having a connecting member for removably connecting the frame to an extremity of a human subject; (2) a support member on the frame for engaging the uninjured portion but not the injured portion; and (3) an attachment member on the frame for attaching the frame to a portion of a moveable resistance mechanism.

  • Patent number: 5262787
    Abstract: A radar performance monitor (RPM) receives a transmitted radar signal from a radar system being monitored and couples the signal to a recirculating loop comprising a SAW delay line in order to produce a series of simulated radar return signals of equal amplitude and by using the same frequency as the received radar signal providing the frequency falls within a predetermined bandwidth of the SAW delay line. The simulated radar return signals are displayed at the radar system and used to evaluate the operation and calibration of a transmitter and the sensitivity and calibration of a transmitter and the sensitivity and calibration of a receiver in the radar system. The radar performance monitor is actuated at the option of a radar operator.

  • Patent number: 4145692
    Abstract: A performance monitor for use with marine radars which produces a visual indication upon the radar display screen only when the radar transmitter power, and the radar receiver sensitivity and tuning are within predetermined limits. An RF sample of the radar transmitted signal is mixed with a local oscillator signal and the resulting IF signal is coupled to an AFC loop which controls the frequency of the local oscillator. If the amplitude of the radar transmitted signal is above a threshold level, a single frequency response signal of fixed power is generated by the performance monitor and transmitted back to the radar antenna. A distinctive test pattern is produced upon the radar display if the radar receiver tuning is accurate and its sensitivity is sufficiently high.
