Systems and methods are provided for determining an acceleration at a location of interest within one of a user's head and neck. At least one of linear acceleration data, angular acceleration data, angular velocity data, and orientation data is produced using at least one sensing device substantially rigidly attached to an ambient-accessible surface of the user's head. The location of interest is represented relative to a position of the at least one sensing device as a time-varying function. An acceleration at the location of interest is calculated as a function of the data produced at the sensing device and the time-varying function representing the location of interest. The calculated acceleration at the location of interest is provided to at least one of the user and an observer in a human-perceptible form.

Detection and characterization of head impacts

Systems and methods are provided for registering a sensor assembly, implemented on a base apparatus, to a desired location associated with a head of a user. A position of a reference point on the base apparatus is determined relative to an external anatomical landmark of the user. A position of the external anatomical landmark is determined relative to the desired location. The position and orientation of the sensor assembly is determined relative to the desired location according to the determined position and orientation of the sensor assembly relative to the reference point, the determined position of the reference point relative to the external anatomical landmark, and the position of the external anatomical landmark relative to the desired location.

Registration of head impact detection assembly

Systems and methods are provided for classifying an impact to a head of a human being as one of a plurality of event classes. A sensor interface is configured to determine an acceleration at a location of interest on the human being from provided sensor data in response to the impact. A feature calculation component is configured to calculate a plurality of impact parameters from the determined acceleration at the location of interest. A pattern recognition classifier is configured to associate the impact with an associated event class of at least three associated event classes according to the calculated plurality of impact parameters. A post-processing component is configured to communicate the associated event class an observer via an associated output device.

Classification of impacts from sensor data

Systems and methods are provided for enhancing a presentation of an athletic event. Data is received at a sensor located at a first location on a first athlete. The data represents an impact applied to the first athlete by a second athlete. One of an acceleration and a force at a second location on the first athlete induced by the impact is determined. A representation of the determined one of the acceleration and the force at the second location on the first athlete is displayed to an audience of the athletic event.

Enhancement of the presentation of an athletic event

An apparatus for replacing a damaged spinal disc in a spinal column includes a first retaining device having an outer surface engageable with a first vertebra of the spinal column and an inner surface. A second retaining device has an outer surface engageable with a second vertebra of the spinal column and an inner surface. A resilient core has a first surface and a second surface. The first surface engages the inner surface of the first retaining device. The second surface engages the inner surface of the second retaining device. The resilient core has a tapered radially outer surface extending from adjacent the first surface to adjacent the second surface. The first retaining device may have a flange extending toward the second retaining device. A concave surface may extend between the first surface and the radially outer surface. The concave surface of the core may engage the flange when the apparatus is free of a load.

Apparatus for replacing a damaged spinal disc

An apparatus for replacing a spinal disc which has a rail extending from the outer surface to connect the apparatus to the first vertebra. The rail extends a first distance from the outer surface adjacent a first end. The rail extends a second distance from the outer surface adjacent a second end. The second distance is greater than the first distance. In another aspect of the apparatus, the first rail extends generally transverse to the first and second ends. The second rail extends generally transverse to the first rail.

Method and apparatus for replacing a spinal disc

An apparatus for replacing a damaged spinal disc in a spinal column includes an artificial disc. The artificial disc includes a resilient core having a first surface and a second surface, a first retaining member connected to the first surface of the resilient core, and a second retaining member connected to the second surface of the resilient core. The first retaining member has an outer surface engageable with a first vertebra of the spinal column and an inner surface facing the first surface of the resilient core. The second retaining device has an outer surface engageable with a second vertebra of the spinal column and an inner surface facing the second surface of the resilient core. A first mounting member is connectable with the first vertebra and the artificial disc to position the artificial disc between the first and second vertebrae. The first mounting member is engageable with the artificial disc after being connected to the first vertebra to guide movement of the artificial disc into position between the first and second vertebrae.

A method for replacing a damaged spinal disc between first and second vertebrae of a spinal column includes connecting a first mounting member with the first vertebra of the spinal column. An artificial disc is moved between the first and second vertebrae and into engagement with the first mounting member to guide the artificial disc into position between the first and second vertebrae. The artificial disc includes a resilient core having a first surface and a second surface, a first retaining member connected to the first surface of the resilient core, and a second retaining member connected to the second surface of the resilient core. The first retaining member has an outer surface engageable with a first vertebra of the spinal column and an inner surface facing the first surface of the resilient core. The second retaining member has an outer surface engageable with the second vertebra of the spinal column and an inner surface facing the second surface of the resilient core.
