Methods and systems are provided for adjusting settings of an ultrasound exam based on monitoring of the exam with an optical camera. One example method includes acquiring images of an ultrasound exam via a camera, analyzing the acquired images in real-time to build a spatial exam model, and adjusting settings of the ultrasound exam in real-time based on the spatial exam model.

A dialysis access site monitoring system may generate a treatment recommendation for treating a condition of an access site based on a video of the access site. The dialysis access site monitoring system may include an apparatus having a processor and a memory coupled to the processor. The memory may include instructions that, when executed by the processor, may cause the processor to generate video information based on a video of a dialysis access site of a patient, determine change in the number of pixels (CNP) information of the video information, the CNP information associated with movement of a skin surface of the patient due to blood flow through the dialysis access site, determine frequency domain information of the CNP information, determine a maximum-to-median power (M2) value of the frequency domain information, and determine at least one access site characteristic based on the M2 value.

The present invention relates to a computer-implemented system and method for preventing users from bending their necks too far forward or past thirty degrees away from vertical during viewing of a handheld electronic device. The system uses a computer-implemented application installed in the device that determines flexion of the user's neck and compares with a threshold to determine a ‘tech neck’ condition. The application generates an alert displayed on the screen of the device to indicate the ‘tech neck’ condition and further, can pause or hang the display when the ‘tech neck’ condition is continued to be determined. The system and method assist in preventing injuries, strains and disabilities to both children and adults that use electronic devices for extended periods of time.

An illumination source may be configured to illuminate the skin of the user. An illumination detector may detect electromagnetic radiation reflected of the skin of the user. A compensation module may be configured to determine the position of the skin of the user relative to the illumination detector. A processor may be configured to determine a heart rate of the user by analyzing information corresponding to an amount of the electromagnetic radiation detected by the illumination detector. The processor may also determine the heart rate of the user by compensating for the position of the skin of the user as determined by the compensation module.

New activity recognition, recording, analysis and control techniques, systems and sensors are provided. In one embodiment, multiple sensory tags with unique identification and data transfer attributes, create positional, movement, orientation and acceleration data and supply it to a control system. The tags may be placed at location(s) on the user's body, clothing, personal effects, exercise equipment and other activity-relevant locations, to enhance activity recognition and mapping. The system may define a personal activity space, sample data preferentially from that space, and perform a simplified form of object-recognition to determine, record and analyze user activities.

A system is disclosed herein for providing a kinetic assessment and preparation of a prosthetic joint comprising one or more prosthetic components. The system comprises a prosthetic component including sensors and circuitry configured to measure load, position of load on a curved surface, joint stability, range of motion, and impingement. In one embodiment, the system is for a ball and socket joint of a musculoskeletal system. The system further includes a computer having a display configured to graphical display quantitative measurement data to support rapid assimilation of the information. The kinetic assessment measures joint alignment under loading that will be similar to that of a final joint installation. The kinetic assessment can use trial or permanent prosthetic components. Furthermore, adjustments can be made to the applied load magnitude, position of load, and joint alignment by various means to fine-tune an installation.

According to the present disclosure, a method of monitoring a patient on an operating room table is provided. The method comprises receiving image data captured by at least one image capture device; and determining a position of the patient relative to the operating table in dependence on the image data. A corresponding system, computer program and non-transitory memory are also provided.

Action recognition methods are disclosed. An embodiment of the methods includes: identifying a video that comprises images of a human body to be processed; identifying at least one image to be processed, wherein the at least one image is at least one of an optical flow image generated based on a plurality of frames of images in the video, or a composite image of one or more frames of images in the video; performing convolution on the at least one image to obtain a plurality of eigenvectors, wherein the plurality of eigenvectors indicate a plurality of features of different locations in the at least one image; determining a weight coefficient set of each of a plurality of human joints of the human body based on the plurality of eigenvectors, wherein the weight coefficient set comprises a weight coefficient of each of the plurality of eigenvectors for the human joint; weighting the plurality of eigenvectors based on the weight coefficient set to obtain an action feature of each of the plurality of human joints; determining an action feature of the human body based on the action feature of each of the human joints; and determining an action type of the human body based on the action feature of the human body.
