Abstract: The following relates generally to design and redesign of digital circuits. In one disclosed embodiment, a circuit is annotated by identifying at least one possible error location according to an error library; the at least one possible error location is localized; and the circuit is redesigned based on the localized at least one possible error location.

Abstract: The following relates generally to analog circuit re-design. Some embodiments identify a candidate component of the circuit by determining that if the candidate component is adjusted or replaced, the circuit will satisfy a requirement metric. In some implementations, an optimization problem or Bayesian reasoning may be used to change parameters of the candidate component to create a replacement component. In some implementations, a replacement component of a different type than the candidate component may be selected by solving a mixed-integer optimization program or by using a non-linear program with continuous parameters.

Abstract: Systems and methods described receive a set of experimental data of connection points of an unknown component of a partially known physical system. The systems and methods set feasibility constraints for an untrained model of the unknown component and simulate the partially known system using the untrained model of the unknown component to generate simulated data at the connection points of the unknown component. Systems and methods then optimize the untrained model based on the feasibility constraints and a comparison of the simulated data and the experimental data to generate a trained model of the unknown component.

Abstract: Described are techniques for distributing audio data to multiple audio devices for generation of a synchronized audio output. A master device may receive audio data from a content server or other remote data source and store the audio data in a local cache. The master device may provide the audio data to multiple slave devices using a single multicast transmission. In some cases, the master device may also provide the audio data to individual slave devices unable to receive the multicast transmission using a network connection. Each slave device may store the audio data in a local cache. To generate the audio output, each audio device may retrieve the audio data from the associated local cache, which may enable the audio data to be distributed without modifying the commands used by audio applications to generate the audio output.

Abstract: Described are techniques for configuring a group of devices to distribute and receive data in a manner that reduces consumption of network resources. A larger group of devices may be divided into subsets of devices, each subset including a master device that provides data to multiple slave devices via a multicast transmission. A master device may be determined based on the respective signal quality between the audio devices and an access point, and the number of other audio devices to which each respective audio device may provide data. Other devices having respective signal quality for communication with the master device that exceeds a threshold may be designated as slave devices. Once a first subset is formed, the remaining devices may be grouped into additional subsets. Remaining devices that are not a part of any subset may receive data via communication with an access point.

The computer creates or edits, within the data repository, profile data of the second entity based on the subset of information items. The computer provides a digital transmission of at least a portion of the profile data of the second entity.

Abstract: In some embodiments, a system may include a passive uniplanar single-balanced millimeter-wave mixer. In some embodiments, a three-port diode-tee IC forming a mixer core is coupled between an end of a slotline balun and a second coplanar balun. The operational bandwidth of a mixer structure is enhanced by optimizing the distance between the mixer diode-tee core and the back-short circuits. The frequency separation of LO and IF signals may be accomplished by means of stand-alone three-port filter-diplexer device. The system may allow wider than a frequency octave operational bandwidth for a frequency converter device all the way into millimeter wave frequencies at the same time as supporting the operational bandwidth for baseband IF signal over more than six frequency octaves. In some embodiments, the system may accomplish a 500 MHz to 34.5 GHz continuous IF bandwidth with RF signal sweeping from 33 GHz to 67 GHz and local oscillator at 67.5 GHz fixed frequency.
