A method and program product includes assigning a first location of at least one embedded device. The embedded device includes at least one sensor and is associated with a one joint capable of movement. The first location is captured by the sensor. A second location of the at least one embedded device is assigned. The second location being captured by observation of the embedded device by at least one external sensor. A pose correspondence between the first location and the second location is established using a model of the joint. The sensor is calibrated by tracking a change in a pose captured by the external sensor and a change in a pose captured by the one sensor as the joint moves.

Aspects of this disclosure relate to improving an athlete's ability to synchronize the movement of their body in time. Certain embodiments provide a feedback system that allows an athlete (or another individual, such as a trainer) to comprehend and optimize the timing of one or more components or features of an athletic movement. Image data, such as video, of an athlete performing physical activity may be utilized (alone or in combination with non-image data) may be used to generate and emit real-time feedback signals to provide an indication of tempo to the athlete. Still further aspects relate to using image and/or other sensor data to detect improper timing and/or movements of an athlete, and in response generating real-time feedback signals.

The invention relates to a method for modeling the mandibular kinematics of a patient, comprising: acquiring at least one stereoscopic image of the face of the patient by means of a stereoscopic camera, constructing, from said stereoscopic image, a three-dimensional surface model of the face of the patient, identifying characteristic elements of the face of the patient on said stereoscopic image or on said three-dimensional surface model of the face of the patient, from said characteristic elements, determining, on said stereoscopic image, respectively said three-dimensional surface model of the face of the patient, reference points, axes and planes of the face of the patient, obtaining a three-dimensional model of the maxillary dental arch and a three-dimensional model of the mandibular dental arch of the patient, registering the three-dimensional models of the dental arches with respect to the reference planes of the three-dimensional surface model of the patient, recording the mandibular kinematics of the patient, applying said recorded mandibular kinematics to the three-dimensional models of the registered dental arches, so as to animate said three-dimensional models.

A method for determining an emotional state of a subject includes receiving the motion based physiological signal associated with a subject, the motion based physiological signal including a component related to the subject's vital signs, and determining an emotional state of the subject based at least in part on the component related to the subject's vital signs.

The disclosed apparatus, systems and methods relate to various devices, systems and methods for gently restraining an unanesthetized laboratory animal, particularly for facial recognition applications. In some applications, the laboratory animal may have been previously cannulated.

Apparatuses, components, devices, methods, and systems for determining jaw movement are provided. An example patient assembly for capturing motion data of a patient includes a clutch configured to be worn by the patient on a dentition of the patient. The clutch includes a dentition coupling device configured to couple to the dentition of the patient and includes an extension member configured to protrude out from the patient's mouth. The clutch also includes a position indicating system rigidly connected to the dentition coupling device. An example position indicating system emits a plurality of light beams. Some examples also include an imaging system and a motion determining device. An example imaging system captures a plurality of image sets that each include at least one of a plurality of screens upon which the light beams project. An example motion determining device processes the captured image sets to determine the motion of the patient's dentition.

A system that wirelessly integrates actual sports equipment with a computer and the internet to allow players remotely located from one another to play a competitive simulated sports game. An individual player may opt to play solo or practice to improve basic techniques. The system includes motion sensors connected to the player and a motion sensing device, all containing circuits and contact or motion sensors coupled with signal processing and radio frequency transmitter circuitry, thereby wirelessly communicate game performance information to a remote receiver-computer. The computer displays player information and visually simulates and controls a game between two players via the internet, having similar equipment and remotely located from each other. Standard sports equipment may be retrofitted with the sensors and associated circuitry to convert such equipment into “smart equipment” for use with the system. The system employs specially developed computer software to process player performance data, control game play, communicate game information between players, generate and control visual simulations and display player performance information.

A computer-assisted surgery system may have a robotic arm including a surgical tool and a processor communicatively connected to the robotic arm. The processor may be configured to receive, from a neural monitor, a signal indicative of a distance between the surgical tool and a portion of a patient's anatomy including nervous tissue. The processor may be further configured to generate a command for altering a degree to which the robotic arm resists movement based on the signal received from the neural monitor; and send the command to the robotic arm.

A method for acquiring gait parameters of an individual is disclosed. The method includes capturing calibration images from foot marker placed on feet or shoes of an individual while an individual is standing still, the calibration images are obtained from a camera worn by the individual, capturing subsequent time-varying images from the foot markers while the individual is walking, and comparing the calibration images to the subsequent time-varying images by a processing unit that is coupled to the camera to determine changes between the initial relative image size of the foot markers and the time-varying images of the foot markers as a function of time to analyze gait of the individual.

An optical marker apparatus or device for tracking and compensating for patient motion during a medical imaging scan can comprise one or more optical markers, one or mounts, and a substrate. The one or more optical markers can be adapted to be detected by one or more detectors and/or cameras of a medical imaging scanner and/or motion tracking system. One or more mounts can be configured to attach the one or more markers to the substrate. The substrate, in turn, can be configured to be attached to one or more regions of a subject patient's body. For example, in some embodiments, a substrate can be adapted to be placed or otherwise attached over a nose bridge of a patient.
