Abstract: A Real-Time Locating System (RTLS) and method for determining real-time spatial coordinates of a user device (UD), and a method for acquiring data associated with the UD are disclosed. Additionally, a method for characterizing data associated with the UD is disclosed. Strategic placement of one or more agents and machine learning algorithms are used in acquiring and processing the data to calculate the real-time location of the UD.

Abstract: Systems and methods for wireless communication of sound signals to multiple discrete speakers to establish a rich wireless audio system for use in multiple environments is provided. In one embodiment of the present disclosure, a computing device receives a multiplexed audio signal containing multiple audio channels and demultiplexes the signal and transmits separate demultiplexed signals to wireless speakers, where the separate wireless signals are played by the individual wireless speakers. In another embodiment of the present disclosure, a computing device receives a multiplexed audio signal containing a left and a right audio signal and demultiplexes the signal and uses the left and right audio signals to create a bass signal for use with a three way sound system. In yet another embodiment of the present disclosure, a wireless speaker is configured to listen and intercept a wirelessly transmitted multiplex signal and demultiplex the signal to play a predetermined audio channel.

Abstract: Partitioning Digital front end and digital signal processing across bus interface is carried out in PC and special circuitry Lower bandwidth of sampled I/Q signal communicated over USB bus is made feasible in the design Embodiments are applicable to architecture design of CPCM Card and CPCM embedded module. The CPCM embedded module can be applied to desktop PC, notebook PC, smart phone, smart USB module, and any other devices which require CPCM functionalities The technique lends itself to both board level and FPCA/ASIC implementations.

Abstract: A cellular personal computer (CPC) modem architecture performs radio frequency (RF) processing at the CPC modem hardware level and some or all CPC modem baseband processing is carried out on a processor (CPU) of an electronic computing device.
