Abstract: A solar-powered position tracker includes a load including one or more of a GPS module, a GPS antenna, a GSM module, or a GSM antenna. The load is powered by a rechargeable battery, which may be charged by one or more of a non-rechargeable primary battery and a solar cell. The solar-powered position tracker includes a battery management system for powering the position tracker by controlling the solar cell, rechargeable battery and the non-rechargeable primary battery. The two-stage battery management system charges the rechargeable battery in two stages and includes a solar management and protection circuit interconnecting the solar cell, and the rechargeable battery. The battery management system is configured to execute a charging process for recharging the rechargeable battery from solar cell and protect the rechargeable battery under a high pulse current discharge process to meet a high current or high pulse current discharge demand by the load.

Abstract: A pressure distribution mapping system includes a flexible M×N textile-based pressure sensor array. with first and second electrode textile layers and a piezoresistive fabric layer with a sheet resistance of at least 60 k-ohm/square positioned between the first and second electrode textile layers. Individual pressure sensors are formed by an intersection between a row electrically-conductive path and a column electrically-conductive path along with the portion of the piezoresistive layer positioned at the intersection. A measurement system measures the resistance of each pressure sensor of the pressure sensor array. The measurement system includes a reading module with first op-amps connected to each row and second op-amps connected to each column. Plural switches switch between pressure sensor-enabled and pressure sensor-disabled positions to minimize a bus line crosstalk effect during pressure sensor reading A processor scans each pressure sensor and generates a pressure distribution profile based on a measured resistance of each pressure sensor.

Abstract: A solventless method of making a dry electrode for an electrochemical cell is provided. A solventless electrode material mixture includes 85-99% electrode active material and from 0-10% conductive carbon additive. A polymer binder system is present from 1-15%. The polymer binder system includes one or more polymer binders. The electrode material mixture is mixed at a temperature greater than a softening point or a melting point of at least one polymer binder of the polymer binder system. The electrode material mixture is kneaded into an electrode material dough. The electrode material dough is formed into an electrode material sheet. At least a portion of the electrode material sheet is affixed to a metal current collector to form an electrode.
