Abstract: Multiple circuits in a computing device can share one or more conductive elements. The use of the conductive element can vary by circuit, such as an antenna radiator for a radio frequency (RF) circuit or an electrode for an electrocardiography (ECG) circuit. The circuitry sharing a conductive element can utilize signals obtained over different frequency ranges. Those ranges can be used to select decoupling circuitry, or elements, that can enable the respective circuits to obtain signals over a respective frequency range, excluding signals over one or more other frequency ranges corresponding to other circuitry sharing the circuit. Such an approach allows for concurrent independent operation of the circuitry sharing a conductive element.

Abstract: A battery management system for an electric vehicle is provided. The battery management system may include a battery pack and a battery controller. The battery controller may acquire a first reading of the battery pack in response to first criteria being met, acquire a second reading of the battery pack in response to second criteria being met, and determine an estimated capacity of the battery pack. The battery controller may further validate the estimated capacity in response to third criteria being met. In one example, the capacity of cells is updated in a closed loop manner where both the new learned values and old valid value are engaged. The different learned values of capacity values are adaptively averaged based on the battery conditions such as temperature, accuracy of learned values, time since last update and depth of aging. The proposed methodology updates capacity in a periodic manner where different operation conditions are accommodated to facilitate capacity estimation.

Abstract: In a URL error-correcting method, after a URL is received from a terminal, a server determines whether a web page corresponding to the URL exists. When there is no web page corresponding to the URL, the server determines that the URL is an incorrect URL. Similarity matching is performed using the URL with a URL in a URL database, to acquire a pre-determined quantity of URLs that are most similar to the URL, as alternative error-corrected URLs. The error-corrected URLs are sent to the terminal. The correctness of a URL is determined by means of determining whether a web page corresponding to the URL exists. When the URL is incorrect, similarity matching is performed with a URL in a URL database to obtain URLs possibly needed by a user, so as to achieve error correction of a URL.

Abstract: The present disclosure relates to a battery capacity active estimation method for an electric vehicle. The method is capable of determining the battery capacity based on estimating a State Of Charge (SOC) of the battery before and after a discharge operation but without having to wait until an establishment of sufficient thermal and electric equilibria in the battery. The estimation of SOC may even be made while the battery is being slowly charged. Depending on the equilibrium state of the battery, SOCs may be either directly obtained by measuring Open Circuit Voltage of the battery when the battery is in electric equilibrium or calculated and estimated when the battery is not in electric equilibrium.
