Abstract: Embodiments described herein are related to contactless data communication. Related systems and methods for contactless data communication are disclosed herein. For example, a magnetic field-based contactless transmitter is disclosed that includes a substrate, a pair of dipole coils disposed on the substrate, and a drive circuit electrically coupled to the pair of dipole coils. To transmit data to a magnetic tunnel junction (MTJ) receiver disposed on a second substrate, the drive circuit is configured to drive the pair of dipole coils so as to generate a magnetic field in-plane to the MTJ receiver. Data can be transmitted from the magnetic field-based contactless transmitter to the MTJ receiver using the magnetic field.

Abstract: In various aspects, the disclosure provides for aggregating bandwidth in broadband subscription services including sending a query to a device and determining that the device is a bridging device; receiving a sharing profile from the bridging device; and routing a first data generated by a local area network (LAN) client to an external network over at least the bridging device using the sharing profile or over a backhaul link; and, in various aspects, further including receiving a second data from the external network over at least the bridging device using the sharing profile or over the backhaul link, wherein the second data is received in response to the first data; and routing the second data to the LAN client.

Abstract: A method and apparatus for generating random binary sequences from a physical entropy source having a state A and a state B by detecting whether the physical entropy source is in the state A or in the state B, attempting to shift the state of the physical entropy source to the opposite state in a probabilistic manner with less than 100% certainty, and producing one of four outputs based on the detected state and the state of the physical entropy source before the attempted shift. The outputs are placed in first and second queues and extracted in pairs from each queue. Random binary bits are output based on the sequences extracted from each queue.

Abstract: A magnetic tunneling junction non-volatile register with feedback for robust read and write operations. In an embodiment, two MTJ devices are configured to store a logical 0 or a logical 1, and are coupled to drive an output node to a voltage indicative of the stored logical 0 or a logical 1. The output of a D flip-flop is fed to the two MTJ devices so that the state of the D flip-flop may be stored in the two MTJ devices during a store operation. During a read operation, the D flip-flop outputs the state of the two MTJ devices. Read disturbances are mitigated with the use of an edge detector coupled to the output node, so that a LOW voltage is provided to the D flip-flop if a rising voltage at the output node is detected.

Abstract: Systems and methods for harvesting dissipated heat from integrated circuits (ICs) in electronic devices into electrical energy for providing power for the electronic devices are disclosed. In one embodiment, energy transferred from one or more ICs in the form of dissipated heat is harvested to convert at least a portion of this dissipated heat into electricity. This power can be used to provide power to the ICs to reduce overall power consumption by the electronic device. The harvested dissipated heat can be supplied to ICs in the electronic device to provide power to the ICs. Alternatively, or in addition, the harvested dissipated heat can be stored in an energy storage device to provide power to the ICs at a later time.
