Patent number: 9660800Abstract: Method for data communication involves receiving with a radio receiver a data signal containing a plurality of data symbols. An analog to digital converter obtain a sample of the data signal at periodic intervals to define a sampling rate which is N times a symbol rate. Thereafter, at least one processing device allocates each sample obtained to a respective one of N sampled data streams in accordance with an allocation sequence, and repeats the allocation sequence after every N samples so that each of the N sampled data streams has a data stream symbol rate equal to the symbol rate. Thereafter, a plurality of data stream data sets defined by the N sampled data streams are validated. Once the validation is completed, a plurality of groups are determined, each comprised of two or more of the stream data sets which have been validated and are identical.Type: GrantFiled: November 6, 2014Date of Patent: May 23, 2017Assignee: Navitas SolutionsInventors: Inseop Lee, Jaesik Lee, Minkyu Lee, Andrew M.

Patent number: 9564762Abstract: A Wireless battery area network permits the wirelessly monitoring and controlling of individual batteries within large-scale battery applications. The system automatically configures its wireless nodes in the network and provides for the linking of a plurality of batteries (10) to a master battery management unit (M-BMU) (100) by establishing a wireless battery area network within a battery pack that include slave units (S-BMU) (210). The entire system may also be controlled by a top level battery management unit (T-BMU) (510). The system and method allows for the monitoring of voltage, current, temperature, or impedance of individual batteries and for the balancing or bypassing of a battery.Type: GrantFiled: August 8, 2014Date of Patent: February 7, 2017Assignee: Navitas SolutionsInventors: Jaesik Lee, Inseop Lee, Minkyu Lee, Andrew M.
