Abstract: Methods, apparatus, systems and articles of manufacture are disclosed to determine the number of people at a location. An example apparatus includes a configuration changer to change a configuration setting of the base station to cause mobile devices to register with the base station, a registration manager to respond to registration requests received from the mobile devices after the configuration setting is changed by storing device identification information for the corresponding mobile devices, and a counter controller to identify a number of the mobile devices at a location of the base station based on the stored device identification information.

Abstract: A tissue fixation device for securing soft tissue to bone includes an expandable outer sheath, and an inner screw in threaded cooperation with the sheath. The expandable sheath comprises opposing walls in hinged engagement. When the screw is inserted into in the sheath, the walls pivot outwardly about a distal hinge to compress a tissue graft against the bone hole, and to lock the device therein. An optional cortical button is secured across the bone hole entrance, and tethered to the fixation device to bolster fixation.

Abstract: Intramedullary medical devices (e.g., intramedullary nails) and methods for their use and manufacture are described herein. The intramedullary medical devices described herein may provide sustained compressive forces across a bone fusion site despite bone resorption processes. Through various embodiments, the intramedullary medical devices described herein may provide non-linear force curves relative to displacement. Intramedullary medical devices are described with multiple elements made of different materials. Examples of intramedullary medical devices are described with shape memory alloys.

Abstract: Methods and apparatus for installing intramedullary medical devices (e.g., intramedullary nails) are described herein. Intramedullary medical devices in accordance with this disclosure provide sustained compressive forces across a bone fusion site despite bone resorption processes. Intramedullary medical devices in accordance with this disclosure include pseudo-elastic shape memory alloys containing nickel and titanium. Portions of intramedullary medical devices, including shape memory alloy elements in the intramedullary medical devices, may have strains imparted upon them through the methods and apparatus described herein. Further aspects of surgery techniques are also performed and controlled through the methods and apparatus described herein.
