Abstract: In an example method, a mobile device obtains a signal indicating an acceleration measured by a sensor over a time period. The mobile device determines an impact experienced by the user based on the signal. The mobile device also determines, based on the signal, one or more first motion characteristics of the user during a time prior to the impact, and one or more second motion characteristics of the user during a time after the impact. The mobile device determines that the user has fallen based on the impact, the one or more first motion characteristics of the user, and the one or more second motion characteristics of the user, and in response, generates a notification indicating that the user has fallen.

Abstract: Pulse-generator-based reciprocal quantum logic (RQL) bias-level sensors are fabricated on an RQL integrated circuit (IC) to sample AC or DC bias values provided to operational RQL circuitry on the RQL IC. The bias-level sensors include pulse generators having strengthened or weakened bias taps (transformer couplings to RQL AC clock resonators or DC bias lines) as compared to bias taps of Josephson transmission lines in the operational RQL circuitry, or Josephson junctions (JJs) with larger or smaller critical currents as compared to JJs in the operational RQL circuitry. Pulse generators with weakened bias taps or larger JJs can have lower limits of their operational ranges placed near an optimal bias point at the centroid of the operating region of the operational RQL circuitry. The bias-level sensors can be staged by relative strength to indicate whether a provided bias value is an improvement when varied over a range.

Abstract: Reciprocal quantum logic (RQL) bias-level sensors are fabricated on an RQL integrated circuit (IC) to sample AC or DC bias values provided to operational RQL circuitry on the RQL IC. The bias-level sensors, or samplers, include Josephson transmission lines (JTLs) or logic gates having strengthened or weakened bias taps as compared to bias taps of JTLs or logic gates in the operational RQL circuitry. Sampler JTLs or logic gates with weakened bias taps to AC clock resonators can have lower limits of their operational ranges placed near an optimal bias point at the centroid of the operating region of the operational RQL circuitry. Staging relative strengths of the bias taps of the samplers in an ensemble of samplers allows for outputs of wrapper circuitry to be indicative of whether a provided bias value is an improvement or optimization of the bias value when varied over a range.

Abstract: Shift register elements of a phase-mode bit-addressable sensing register sample varied AC or DC bias values provided to operational RQL circuitry on the RQL IC via clock resonators or DC bias lines. The shift register can be constructed of phase-mode D flip-flops and JTLs as data and clock lines. A method of using the sensing register includes shifting in a data bit pattern while a bias parameter (e.g., AC amplitude, DC value, or phase) is set to a nominal value; stopping the logical clock that controls the shifting of values through the sensing register, varying the bias parameter value, inputting one assertion SFQ pulse or reciprocal pulse pair into the logical clock, restoring the bias parameter to the nominal value, restarting the logical clock to shift out an output data bit pattern, and observing the output data bit pattern to determine the effect of the bias parameter value change.

Abstract: An output-amplifier-based reciprocal quantum logic (RQL) bias-level sensor is used to measure and/or calibrate bias parameters of AC and/or DC bias signals provided to RQL circuitry. The bias signals can include an output amplifier output bias current. The bias-level sensor includes a stack of DC SQUIDs that are supplied their inputs from outputs of respective Josephson transmission lines (JTLs) to which the SQUIDs are transformer-coupled. Staging relative strengths of the bias taps of the JTLs, or the critical currents of the Josephson junctions in the DC SQUIDs, allows an output voltage signal of the bias-level sensor to be indicative of whether a provided bias value is an improvement or optimization of the bias value when varied over a range. The outputs of two such bias-level sensors driven by I and Q clocks can be compared to adjust AC bias amplitudes of the clocks. Relative clock phase can be similarly adjusted.

Abstract: An athletic footwear with improved midsole that is having a helical network. The helical network can morph itself under compressive force. The helical network is made from units of an hourglass shape geometry, each unit having an upper member and a lower member. Each unit is of a wireframe geometry that is integrated with adjacent units to form a networked layer. When an external pressure is applied to the networked layer, such as when the feet wearing the footwear land on a ground, the wireframe legs in the upper member and lower member twists for providing cushioning and resiliency.

Abstract: Embodiments of the disclosure provide blockchain-implemented methods and systems for secure data transfer and/or storage via the use of data hiding (e.g. steganography algorithms, watermarking etc). In accordance with one aspect, a data hiding algorithm is applied multiple times to a portion of secret data to embed it in a cover file. This constructs layers of hidden data, e.g. secret data hidden in an image that is then used as secret data in a further cover file and so on. Each layer can incorporate encryption and authentication techniques to further enhance security. The final layer or a compressed version is provided within a blockchain transaction. Additionally or alternatively, the secret data can be split into a plurality of shares. This can be achieved using a splitting scheme such as, for example Shamir's Secret Sharing Scheme. Different shares of the secret data can then be encrypted before being hidden within a cover file.

Abstract: Non-destructive read out (NDRO) circuits are provided for use in reciprocal quantum logic (RQL) superconducting systems. Each NDRO circuit includes a “body” circuit that provides a single or multi-state sub-critical bias current to one or many independent “tail” circuitries. Each “tail” has minimal effect on the “body” thereby preventing any interference or destruction to the state of the “body” circuitry. The circuits reduce device count and thereby increase circuit density, simplify and reduce the cost of fabrication, and provide functionality not available in existing designs, such as the ability to write a state and read it in the same operation cycle. The NDRO circuits provide more compact unit cells useful in memory or logic arrays, demanding fewer resources with increased functionality. The circuits also provide compact cells for AND, AND-OR, A-NOT-B, inverter, multiplexer, and demultiplexer gates.
