  • Patent number: 10357688
    Abstract: An exercise feedback system monitors the performance of athletes wearing a garment with sensors while exercising. The sensors generate physiological data such as muscle activation data, heart rate data, or data describing the athlete's movement. The system extracts features from the physiological data and compares the features with reference exercise data to determine metrics of performance and biofeedback. Based on the physiological data, the system may also modify exercise training programs for the athlete. The exercise feedback system can display the biofeedback using visuals or audio, as well as modified exercise training programs, via the athlete's client device in real time while the athlete is exercising. By reviewing the biofeedback, the athlete may correct the athlete's exercise form to properly use the target muscles for the exercise, or change the certain workouts to personalize the training program.

    Abstract: Systems and methods for diagnosing a user's condition based on his gait. A sensor module with multiple sensors is placed inside a user's shoe and biometric data is gathered from the sensors when the user takes a step or walks. The data is used to generate loops as the various sets of data is plotted against each other. The loops obtained from the data are then compared against stored loops previously obtained. Based on the results of the comparison, the user's condition is diagnosed using predetermined indicators of specific health issues. Using the biometric data and in conjunction with data from various databases, it can be determined whether the user has a specific condition, whether a specific condition is worsening, or whether a specific condition is improving.

  • Patent number: 9668927
    Abstract: In some embodiments, a pressure-sensitive mat and a monitoring device are part of a pressure relief compliance system. The pressure-sensitive mat is placed between a seat cushion and a chair. When a user sits on the cushion, the system will monitor the time the person spends applying pressure and will notify a user with an alarm or by other means when the preset sitting limit is reached. Also a novel method for measuring and adjusting the amount time spent applying and releasing pressure. In some embodiments, rather than simply measure time spent applying pressure, the system will allow the user to “buy back” sit time when the user releases pressure. The rate at which the system will credit the user with a “buy back” of sitting time may in some embodiments be directly proportional to the amount of time the user spends performing a pressure release.

  • Publication number: 20150080722
    Abstract: A device for correlating trend data with respect to a patient's weight and lower extremity displacement can identify conditions indicative of congestive heart failure. An imaging mechanism is operable to measure lower extremity displacement over a period of time. An over-time trend analysis of both the patient's weight and the lower extremity displacement measurements is performed to determine whether over a particular sample period an increase in a patient's lower extremity displacement can be correlated with an increase in the patient's weight. When such a correlation does not exist, an alert can be issued of conditions indicative of congestive heart failure.

  • Patent number: 8951211
    Abstract: Parameters related to use of a prosthesis by a patient with a limb amputation are monitored using a tool that includes one or more piezoelectric force sensors. The resulting data are processed for use both in short and long term management of amputee patients. The sensor is a small modular unit that fits within or between traditional prosthetic components, e.g., below a prosthesis socket. The data produced by the tool are collected, processed, and stored. Optionally, the data are periodically communicated to a remote site via a network, e.g., over the Internet. The device and associated software used to process the data can be used to characterize activities conducted by a prosthesis user, to determine pistoning or threatening interface stress distributions between the limb and socket, mal-alignment of the socket, use of improper components, and other possibly undesired conditions that the amputee patient using the prosthesis may be experiencing.

    Abstract: The invention relates to a method for determining stretch values and movement of body parts, e.g. a foot, by analysing stretch data from a stretch sensor. By analysing data from the stretch sensor it is possible to determine stretch samples which are associated with particular motion phases. Thereby the stretch values determined from the stretch samples have a particular physical meaning since they are associated with particular motion phases.

  • Patent number: 8840570
    Abstract: A method and apparatus for reliably positioning a 3-segment limb, such as a leg or arm for imaging and medical analysis, which can accommodate for the patient's “natural alignment”. The apparatus positions the limb in such a way that the position of the proximal segment is controlled while an known external torque is applied at a known rate to the distal segment. The location of each of the limb's three segments is recorded using either external or internal measurement techniques, and the relative motions between the proximal and intermediate segments are used in the orthopedic evaluation of the proximal joint. Furthermore, the relative motions between the intermediate and distal segments are used in the orthopedic evaluation of the distal joint. By applying a known torque at a known rate, clinicians will be provided with valuable information related to joint range of motion, stability, laxity, and compliance.
