Abstract: The present disclosure generally relates to the secure exchange of data. In some implementations, an example method involves receiving data from a number of independent data sources. The method also includes storing the data in a central repository where at least a first portion of the data is homomorphically encrypted, receiving a data request from a data requester, and analyzing the stored data without decrypting the homomorphically encrypted data to determine an aggregated subset of data relevant to the data request. The aggregated subset of data may include at least some of the homomorphically encrypted data. The method also includes providing data request results that include or are derived from the aggregated subset of data to the data requester.

Abstract: An example method may include determining a desirability of weather of a destination and determining a travel cost to travel to the destination. In some embodiments, the method may also include presenting, to a user, the destination, an indication of the desirability of weather of the destination, the travel cost, and a specific upcoming time period for travel without receiving any information from the user regarding a time period for travel. In these or other embodiments, the method may also include presenting, to the user, the destination, the indication, the travel cost, and a specific upcoming time period for travel without receiving any information from the user regarding preferred weather conditions. In these or other embodiments, the method may also include presenting, to the user, the destination, the indication, the travel cost, and a specific upcoming time period for travel without receiving any information from the user regarding the destination.

Abstract: Systems and methods for storing and/or communicating digital data associated with amplitudes and phases of a virtual periodic waveform having a designated period between components include, in one embodiment, circuitry that converts a first amplitude and a first phase to a first corresponding voltage or current and applies the first corresponding voltage or current to a first one of the plurality of components, such as conductors connecting integrated circuit chips or capacitors of a DRAM device, and converts the first amplitude and the first phase to (n?1) corresponding voltages or currents based on amplitudes of the periodic waveform phase shifted by about m*(360/n) relative to the first phase where m is indexed from one to (n?1) and applies each corresponding voltage or current to an associated component. Decoding is performed by comparing magnitudes of the component signals relative to one another rather that to a plurality of thresholds.

Abstract: The preferred embodiments described herein provide a medical diagnostic ultrasound imaging system with a rotatable user interface element having a non-rotatable indicator. In one preferred embodiment, a medical diagnostic ultrasound imaging system user interface is provided with a user interface element comprising a rotatable portion disposed around a non-rotatable portion that comprises an indicator identifying a function of the user interface element. With this preferred embodiment, the indicator does not rotate with rotation of the rotatable portion. In another preferred embodiment, a medical diagnostic ultrasound imaging system is provided with a user interface comprising a rotary input device comprising a rotatable shaft, an inner member disposed around and fixed with respect to the rotatable shaft, and an outer member disposed around the inner member and coupled with the rotatable shaft.
