  • Patent number: 11954994
    Abstract: A method includes receiving, from a plurality of magnetic field receivers including magnetic sensors, data characterizing samples obtained by the plurality of magnetic field receivers, the samples of a combination of a first magnetic field and a second magnetic field resulting from interaction of the first magnetic field and an object; determining, using the received data, a polarizability index of the object, the polarizability index characterizing a magnetic polarizability property of the object; classifying, using the determined polarizability index, the object as threat or non-threat; and providing the classification. Related apparatus, systems, techniques, and articles are also described.

  • Patent number: 10341261
    Abstract: A device that includes a plurality of transceivers configurable to simultaneously operate with a combination of bonded and unbonded transceivers. A first transceiver of the plurality of transceivers is operable at a first data rate, and a second transceiver of the plurality of transceivers is simultaneously operable at a second data rate that is different than the first data rate. The first and second transceivers are operable as bonded transceivers and wherein a third transceiver, of the plurality of transceivers, is simultaneously operable at a third data rate and the third transceiver is not bonded with any other transceiver.

  • Publication number: 20160212275
    Abstract: A stable Low Power Mode (LPM) for multicarrier transceivers is described that at least provides transmit power savings while enabling receiver designs that can easily operate without the detrimental effects of fluctuating crosstalk. In one exemplary embodiment, the LPM achieves power savings by reducing the number of used subcarriers without actually performing a power cutback on those subcarriers, thereby allowing a receiver to measure the SNR or noise levels and determine the crosstalk noise on the line regardless of a crosstalking modem being in a LPM or not.

  • Publication number: 20140362863
    Abstract: At a transmitter, an ATM cell stream is received from the ATM layer and is distributed on a cell-by-cell bases across multiple DSL PHY's. At the receiver, the cells from each DSL PHY are re-combined in the appropriate order to recreate the original ATM cell stream, which is then passed to the ATM layer.
