Abstract: Used batteries are screened based on a measured Sectional Constant-Current Impulse Ratio (SCCIR). A used battery is partially charged over a small voltage range using a Constant Current (CC) until a voltage target is reached, and the current integrated to obtain the CC charge applied, Qcc. Then the battery continues to be charged using a Constant Voltage (CV) of the voltage target until the charging current falls to a midrange current target before the battery is fully charged. The current is integrated over the CV period to obtain the CV charge applied, Qcv. The measured SCCIR is the ratio of Qcc to (Qcc+Qcv) and is input to a calibration curve function to obtain a modeled State of Health (SOH) value for sorting. The calibration curve function is obtained by aging new batteries to obtain SCCIR and SOH data that are modeled using a neural network.

Abstract: Time-varying scent determined by audio-meaningful events, such as gun firing, in an audio signal is generated by first computing a spectrogram thereof. A fingerprint, each having feature points, can be extracted from the spectrogram over a time window. The plurality of feature points is hashed to give a hash code. A sequence of hash codes obtained over multiple time windows is correlated with predetermined hash-code segments of known audio-meaningful events stored in a database. A matched audio-meaningful event having a highest correlation is identified. The scent-generating recipe corresponding to the matched audio-meaningful event is retrieved. Atomizers are used to vaporize scent-generating substances to generate the time-variant scent. Since the hash code has a fixed length and a smaller size than the plurality of feature points, storage requirements of the database and computation requirements of correlation calculation are reduced by using the hash code rather than the plurality of feature points.
