  • Publication number: 20180226723
    Abstract: Selective focusing of electromagnetic energy via the electromagnetic time reversal in the near field of a metamaterial. The disclosure begins with fundamental mathematics, and then is extended to the experimental realm where focusing in space and time of the magnetic fields in the near field of a 1-Dimensional metamaterial is shown. Under time reversal focusing, peak instantaneous fields at receiver locations are at minimum 200% greater than other receivers. The strongly-selective focusing capabilities of the system can be employed to show individual and selective powering of light emitting diodes connected to coil receivers placed in the near field of the metamaterial. The results show the possibility of improving display technologies, near field imaging systems, increasing channel capacity of near field communication systems, and obtaining a greater control of energy delivery in wireless power transfer systems.

  • Patent number: 9881273
    Abstract: An object recognition device that senses electrical signals conducted by the body of a human user (e.g., as a result of direct contact with or close proximity to a device emitting or conducting electromagnetic noise), compares the sensed electrical signals to a plurality of signatures of electrical signals produced by a corresponding plurality of types of electrical and electromechanical devices to determine the type of electrical or electromechanical device that generated the electrical signals sensed by the sensor, and communicates information to the human user related to or triggered by the electrical or electromechanical device.

  • Publication number: 20170323501
    Abstract: An RFID system in which at least one of the RFID tag antenna and the RFID reader antenna has an impedance matching network associated therewith in order to better match the impedances of the two antennas. This impedance matching places the antennas into an over-coupled regime once they are within a reasonable distance of each other (e.g., 2 to 50 mm). It also increases the Q-factor of the improved antenna, which can greatly increase the range at which the RFID reader can read the RFID tag. This improved RFID system may be used in any of a variety of application, including operating a door lock mechanism.

  • Patent number: 9805232
    Abstract: There are provided systems and methods for a user interaction with an object having a wireless tag with an antenna. An example system includes a memory storing a tag processing software, and a hardware processor executing the tag processing software to receive a signal from the wireless tag of the object via the antenna, the signal including a wireless tag identification (ID) uniquely identifying the wireless tag, identify the object using the wireless tag ID, extract one or more communication channel parameters from the signal, determine the user interaction with the object based on the one or more communication channel parameters extracted from the signal.

  • Publication number: 20170270198
    Abstract: A technique for identifying individual instances of electronic devices. This is done by using a basic RFID reader to read the RF emissions from the electronic device to obtain an emitted electromagnetic spectrum and compare it to a library of emitted electromagnetic spectrums of different instances of that type of electronic device and, based on that comparison, finding a best match and identifying the electronic device as being a particular instance of that type of electronic device. This comparison may be made by computing Euclidean distances between vectors that are based on the measured electromagnetic spectrums.
