Publication number: 20140125453Abstract: A wireless device access system that employs directional antennas for short-range wireless communication to detect the proximity and orientation of a user device with respect to a structure is disclosed. The access system receives and authenticates an unlock request and confirms the proximity and orientation of the user device prior to transmitting an unlock command to the structure. Additionally, the wireless device may require the proximity of a user token prior to operation and/or the access system may include an override within the structure blocking any unlock command.Type: ApplicationFiled: December 13, 2013Publication date: May 8, 2014Inventors: Jim E. McIntyre, Andrew Joseph Robertson, William Benjamin Robertson

Publication number: 20140125455Abstract: A system and algorithms to authenticate a person where a system only has some standard personal text data about the person, and cannot have a real biometric template obtained using an enrollment procedure. The authentication allows access to restricted resources by the person. This method is especially useful when it is used as an auxiliary authentication service with other methods such as password or Callback that dramatically lower the chances for an imposter.Type: ApplicationFiled: January 14, 2014Publication date: May 8, 2014Applicant: Memphis Technologies, Inc.Inventors: Yaron Menczel, Yair Shachar

Publication number: 20140125460Abstract: The subject matter relates to methods for communicating with an RFID tag that is positioned out of the line-of-sight of a communications device. A passive reflector is provided corresponding to an antenna resonant at the operating frequency of the tag. The antemia may be supported by an insulative or conductive wand for manual placement within the line-of-sight of both the tag and a communications device wishing to communicate with the tag. The passive reflector receives signals from either or both the tag and communications device and retransmits the signals. In this manner signals are able to “turn a comer” to improve communications capabilities.Type: ApplicationFiled: May 27, 2011Publication date: May 8, 2014Applicants: MICHELIN RECHERCHE et TECHNIQUE S.A., COMPAGNIE GENERALE DES ETABLISSEMENTS MICHELINInventors: Jay Clifford Sinnett, Harold S.
