Abstract: A system for intra-operatively registering a pelvis comprising an acetabulum with a computer model of the pelvis in a coordinate system. The system may include: a) a surgical navigation system including a tracking device; and b) at least one computing device in communication with the surgical navigation system. The at least one computing device: i) receiving first data points from first intra-operatively collected points on an articular surface of the acetabulum, the first data points collected with the tracking device; ii) receiving a second data point from a second intra-operatively collected point on the pelvis, the second data point collected with the tracking device, the second data point corresponding in location to a second virtual data point on the computer model; and iii) determining an intra-operative center of rotation of the femur relative to the pelvis from the first data points.

Abstract: To improve user interaction with a venue, a venue management system is associated with the venue and maintains information associated with users and with vendors associated with the venue. The venue management system receives orders for products or services from users and communicates the received orders to vendors associated with the venue to be fulfilled. The venue management system dynamically modifies communication of orders to various vendors associated with the venue for fulfillment to expedite order fulfillment. To modify communication of orders to vendors, the venue management system accounts for times for different vendors to fulfill orders, delivery times from vendors to users, resources used to fulfill orders by various vendors, and distances between various vendors and users placing orders.

Abstract: A system and method for providing a composite audiovisual program for rendering by a video player. The method includes receiving a request for available program segments and sending information relating to the available program segments. Selection information corresponding to selected ones of the available program segments that have been selected for inclusion in a play queue is also received. Available program segments may be selected in response to a single gesture provided through a user interface of an application program including the video player. The method further includes receiving requests for a sequence of segment files identified by variant playlist information associated with the selected ones of the available program segments. The sequence of segment files may be provided by a media repository such that the sequence of segment files are rendered by the video player without buffering between the selected ones of the available program segments.

A pole extends upwardly from the platform and is affixed to the platform. A weight, defining a hole passing therethrough, is disposed on the platform so that the pole passes through the hole. A top plate is affixed to the top of the pole and includes attachment structures disposed about the top plate. An attachment device is coupled to one of the attachment structures. A redirecting device is coupled to one of the attachment members. An elastic cord is attached to the attachment device and is engaged with the redirecting device so that the cord extends radially away from the pole. An exercise device is affixed to the end of the cord.

Abstract: A handleless surgical stay includes an elastomeric band with a longitudinal body having a first end. The surgical stay further includes a tissue retention member including a tissue engaging portion and an anchor portion. The anchor portion is coupled to the first end of the elastomeric band such that the tissue engaging portion extends outwardly relative to the first end. Substantially all of the elastomeric band can be configured for engagement with a surgical retractor frame such that the stay does not include a handle.

Abstract: A haptic robotic system for reaming an acetabulum prior to inserting an acetabular cup is more accurate than conventional instruments and may reduce the risk of dislocation and improve durability of a hip implant. Disclosed is a three-dimensional tool path, referred to as a haptic volume. Once the haptic volume is implemented into the software of a haptically constrained surgical robotic system, the cutting tool or reamer can only be utilized within the haptic volume. The haptic volume guides the surgeon in preparing the final reamed bone surface with a greatly reduced chance of the reaming unintended bone and greatly increases the chance that the reaming procedure may be carried out using one reaming tool, or using a single-stage reaming process.

Abstract: An athlete training apparatus includes a platform, a force redirecting device that is mounted on the platform, an elastic member, a first user coupler and a second user coupler. The elastic member has a first end and an opposite second end and is engaged with the force redirecting device. The first user coupler is coupled to the first end of the elastic member and is also configured to be worn by a first individual. The second user coupler is coupled to the second end of the elastic member and is configured to be worn by a second individual. When the first individual stands in the standing area and when the second individual applies a force to the elastic member, the force redirecting device redirects a portion of the force to the second user coupler so that a force having a downward vertical component is applied to the first individual.
