Abstract: Concepts and technologies disclosed herein are directed to secondary short-range wireless assist for wireless-based access control. According to one aspect, a method can include receiving, at an access control system, a first identifier via a near-field communications (“NFC”) reader associated with an entryway to an area. The NFC reader can receive the first identifier from an NFC component of a mobile device. The method can include receiving, at the access control system, a second identifier via a wireless transceiver associated with the area. The wireless transceiver associated with the area can receive the second identifier from a wireless communication component of the mobile device after the mobile device has entered the area through the entryway. The method can also include determining, by the access control system, that the first identifier and the second identifier constitute an authentication pair that identifies the mobile device as being authenticated to access the area.

Abstract: Apparatus, methods and systems facilitating communications via a mobile internet-enabled connection interface are provided. One apparatus is configured to perform various operations, including performing a first type of security function associated with determining whether an information package is authorized to be received and downloaded to a device other than the apparatus, wherein the information package is associated with updating a functionality of the device; and performing a second type of security function associated with identifying an authorized user of the apparatus.

Abstract: A three-dimensional position and orientation tracking system uses accelerometers to measure acceleration of a moveable object (e.g., a head-mounted display unit or a data glove). A tracking processor generates both position and orientation information on the object relative to a simulation environment as a function of the acceleration data. In one embodiment, a simplified radar-based tracking system is disposed relative to the object and periodically provides additional tracking data on the object to the tracking processor. The tracking processor uses the additional data to correct the position and orientation information using a feedback filter process. The position and orientation information signals generated can be used, for example, in a simulation or virtual reality application. Position and orientation information is received by a simulation processor relative to the object. The simulation processor modifies a simulation environment as a function of the position and orientation information received.
