摘要： Calibration of the state-of-charge (SOC) of a battery-based energy storage system used with a regenerative drive uses an SOC-open circuit voltage (V?oc#191) correlation. The battery is partially charged or discharged to assure operation defined by V?oc#191 following a known V?oc#191-SOC profile, such as a charge or discharge boundary curve. The partial charging/discharging may be synchronized with a traffic profile of an elevator system driven by the regenerative drive. A V?oc#191 measurement is made, and by enhancing the relaxation dynamics of V?oc#191 through regulating battery usage with a reference to traffic profile, a V?oc#191 is estimated more reliably. Using the estimate V?oc#191 and the known V?oc#191-SOC profile, state-of-charge of the battery is determined.

摘要： Provided in the present invention is an adjustment and design method of an illumination system matched with multiple objective lenses in an extreme ultraviolet lithography machine; the illumination system to which the method is applied comprises a light source, a collection lens, a field compound eye, a pupil compound eye and a relay lens group; the method specifically comprises the steps: before a projection objective lens of an extreme ultraviolet lithography machine is replaced, calculating aperture angles of emergent ray of a relay lens A on a meridian plane and a sagittal plane by means of ray tracing; after the projection objective lens of the extreme ultraviolet lithography machine is replaced, taking out a central point of a exit pupil plane as an object point for ray tracing; adjusting inclination angles and positions of the relay lens A and a relay lens B, and adjusting inclination angles of central compound eye units of the pupil compound eye and the field compound eye, till an image plane of a current illumination system approximates to an arc-shaped image plane corresponding to the projection objective lens. By adjusting the illumination system on the basis of the adjustment method of the present invention, an illumination system matched with the projection objective lens system can be obtained, which dramatically reduces the cost of designing a projection lithography machine.

摘要： Systems and methods are provided for scoring non-native, spontaneous speech. A spontaneous speech sample is received, where the sample is of spontaneous speech spoken by a non-native speaker. Automatic speech recognition is performed on the sample using an automatic speech recognition system to generate a transcript of the sample, where a speech recognizer metric is determined by the automatic speech recognition system. A word accuracy rate estimate is determined for the transcript of the sample generated by the automatic speech recognition system based on the speech recognizer metric. The spontaneous speech sample is scored using a preferred scoring model when the word accuracy rate estimate satisfies a threshold, and the spontaneous speech sample is scored using an alternate scoring model when the word accuracy rate estimate fails to satisfy the threshold.

摘要： A mobile electronic device and a sound playback method thereof are provided. The mobile electronic device includes a sensor, a speaker, and a controller coupled to the sensor and the speaker. The sensor detects whether the speaker is blocked or not. When the speaker is blocked, the controller multiplies a sound signal by a transfer function and then outputs the multiplied sound signal. The speaker plays the sound signal outputted by the controller. The transfer function changes the direction in which the speaker plays the sound signal.
