  • Publication number: 20240154121
    Abstract: A lithium-ion battery electrode includes a current collector and n electrode plate layers laminated on the current collector, n being an integer greater than or equal to 2. The electrode plate layer contains a pore-forming agent. A content of the pore-forming agent in the electrode plate layers gradually increases along a direction gradually away from the current collector. The pore-forming agent is selected from an electrolyte solution additive which is solid at normal temperature.

  • Patent number: 9201148
    Abstract: In a receive system, a plurality of correlators correlate a received signal with a plurality of delayed versions of a reference signal to generate a plurality of correlator outputs. A timing error detector estimates an optimal timing based on a set of correlator outputs, and determines a timing error based on (i) the estimated optimal correlation point and (ii) an existing timing, such that the timing error is hard or soft limited between two positive thresholds and two negative thresholds.

  • Patent number: 9188678
    Abstract: In accordance with the teachings described herein, system and methods are provided for a GPS PRN code interpolation scheme with a reduced memory requirement. An example GPS receiver system may include a memory, a local PRN code generator, and an interpolator. The memory may be used to store GPS PRN code received from a global positioning satellite. The local PRN code generator generates a replica PRN code having a repeating code that includes at least a first epoch and a second epoch. The interpolator determines an offset point in the first epoch of replica PRN code and interpolates the replica PRN code at a predetermined sample rate to generate an interpolated replica PRN code for use in correlating with the GPS PRN code.
