Abstract: Systems and methods for a digital asset wallet system to generate blockchain wallets using universal wallet libraries and/or modular wallet component(s) to implement first functionality that is universally shared across various blockchain networks. Additionally, network sidecar(s) may be generated for a given blockchain network to implement second functionality specific to the given blockchain network in tandem with the universal wallet libraries and/or modular components. The first functionality of the wallet library map then be mapped to the second functionality specific to the given blockchain network using the network sidecar(s). The digital asset wallet system may then generate a requested wallet based on the mapping between the first functionality of the wallet library and the second functionality of the network sidecar.

Abstract: Apparatus includes a device housing, a device face, a printed circuit board (PCB), and an antenna array. The device housing has a shape characterized by an axis, a planar housing surface that is perpendicular to the axis, and a housing sidewall that is parallel to the axis. The housing sidewall is positioned along a periphery of a planar housing surface. The device face is positioned at an opposite end of the device housing from the planar housing surface. The PCB is positioned between and parallel to the planar housing surface and the device face. The antenna array has multiple antenna elements at least some of which are electrically coupled to the PCB. The antenna array is configured to concentrate radiation of radio waves laterally through a radiation plane that is parallel to the sidewall of the housing and that is perpendicular to the device face and the planar housing surface.

Abstract: A text to speech system (100) uses differential voice coding (230, 416) to compress a database of digitized speech waveform segments (210). A seed waveform (535) is used to precondition each speech waveform prior to encoding which, upon encoding, provides a seeded preconditioned encoded speech token (550). The seed portion (541) may be removed and the preconditioned encoded speech token portion (542) may be stored in a database for text to speech synthesis. When speech it to be synthesized, upon requesting the appropriate speech waveform for the present sound to be produced, the seed portion is preappended to the preconditioned encoded speech token for differential decoding.

Abstract: A system (100) and method (400) for monitoring a data channel for discontinuous transmission activity can include a monitoring unit (210), in which the monitoring unit can identify a source of modifying the discontinuous transmission activity based on receipt of an identifier packet, and an equalizer (214) coupled to the monitoring unit. When the monitoring unit determines that an identifier packet has been modified by a source over a communication channel, the equalizer can apply a compensatory equalization associated with the identified source to compensate for equalization applied at the source.
