Patents by Inventor Lucian Cristache

Lucian Cristache has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10495745
    Abstract: A localization system includes a plurality of radio frequency readers having transceivers and antennas. Adjustable configuration settings allow for configuration adjustments including signal strength, antenna gain, antenna polarization, and antenna orientation. A computer system is coupled with the radio frequency readers and is configured to determine a first location of an object based on data from the readers and compare it with a second location of the object based on data from a global positioning system device. The computer system is configured to perform an action based upon the determination that the first location and the second location are within a range, including that they are at the same location.

  • Patent number: 10262166
    Abstract: A networked radio frequency identification system includes a plurality of radio frequency identification (RFID) tag readers, a computer in signal communication with the RFID tag readers over a network, and a software module for storage on and operable by the computer that localizes RFID tags based on information received from the RFID tag readers using a network model having endpoints and oriented links. In an additional example, at least one of the RFID tag readers includes an adjustable configuration setting selected from RF signal strength, antenna gain, antenna polarization, and antenna orientation. In a further aspect, the system localizes RFID tags based on hierarchical threshold limit calculations. In an additional aspect, the system controls a locking device associated with an access point based on localization of an authorized RFID tag at the access point and reception of additional authorizing information from an input device.

  • Patent number: 10209354
    Abstract: A semantic sensing system includes a semantic engine coupled to one or more sensing entities, and a memory having a plurality of semantics and semantic inference rules. A semantic engine is configured to interpret the plurality of rules to determine a composite semantic by inferring a first semantic, determining a second sematic based on an external input, and infer a composite sematic based on the first and second semantics and a semantic inference rule.

  • Patent number: 10191149
    Abstract: A semantic sensing system includes a first sensing entity and a semantic engine coupled with the first sensing entity. A memory is associated with the semantic engine and stores a plurality of semantics. The memory further stores a first semantic inference rule for a first semantic. The semantic engine is configured to perform a control action by inferring a first semantic based on an input from the first sensing entity at a first time and the first semantic inference rule, adjusting a weight for the first semantic based on an external input, and perform the control action based on the adjusted weight for the first semantic.

  • Publication number: 20180341013
    Abstract: An access control system and method for permitting access by a user having a mobile device, based on a determined location for the user and additional authentication information sent to the mobile device. A computer system has stored programming instructions configured to cause the computer system to identify the user at an area-based location, send a first access code to the mobile device representing additional authorizing information, receive the first access code within a predefined interval of time, and unlock the access based on a determination that the access code is valid and the identification of the user at the area-based location.

  • Publication number: 20180329048
    Abstract: A semantic sensing system includes a semantic engine coupled to one or more sensing entities, and a memory having a plurality of semantics and semantic inference rules. A semantic engine is configured to interpret the plurality of rules and to perform an action by inferring a first semantic and a second semantic based on inputs from the first sensing entity. The semantic engine infers a composite semantic and identifies an action applicable to the composite semantic to perform the action.
