    • A quick discharge circuit includes a reference voltage source, a power supply voltage monitoring circuit, a control circuit, and a discharge circuit. The reference voltage source provides a threshold voltage for quick discharge; the power supply voltage monitoring circuit collects change conditions of a power supply voltage; the control circuit performs logical control according to the power supply voltage collected by the power supply voltage monitoring circuit and the threshold voltage provided by the reference voltage source to determine whether the discharge circuit is ON. With the quick discharge circuit, when a terminal product is powered off, an input bulk capacitor of a DC-DC circuit is discharged quickly so that the voltage thereof rapidly drops to a safe voltage range. When the terminal product is powered on again quickly, it is guaranteed that a soft start circuit works normally so as to implement slow increase of power-on voltage and current.
    • 快速放电电路包括参考电压源,电源电压监视电路,控制电路和放电电路。 参考电压源为快速放电提供阈值电压; 电源电压监控电路收集电源电压的变化条件; 控制电路根据由电源电压监视电路收集的电源电压和由参考电压源提供的阈值电压来执行逻辑控制,以确定放电电路是否为ON。 利用快速放电电路,当终端产品断电时,DC-DC电路的输入大容量电容器被快速放电,使其电压迅速下降到安全的电压范围。 当终端产品快速上电时,保证软启动电路正常工作,以实现上电电压和电流的缓慢增加。

    • Embodiments relate to management of data accessed from a database. A usage tracking engine of an application layer overlying a database, may automatically track (e.g. with a time stamp) access to specific data objects by particular users. This automatic tracking may be based upon one or more of the following: frequency of access, recency of access, user geographic location, and user calendar events. Based upon this data, the tracking engine applies an algorithm to automatically identify those data objects meriting special handling for quick access (e.g. for placement in a “shelf” or other construct readily accessible to the user). A heuristic learning module may generate a data object ranking based upon the usage data, and communicate that ranking to the usage tracking engine to determine a data object's eligibility for placement on the “shelf”. Such ranking may consider personalized settings, and/or a user's past manual shelf placement of data object(s).
    • 实施例涉及从数据库访问的数据的管理。 覆盖数据库的应用层的使用跟踪引擎可以由特定用户自动跟踪(例如,使用时间戳)对特定数据对象的访问。 该自动跟踪可以基于以下中的一个或多个:访问频率,访问的新近度,用户地理位置和用户日历事件。 基于该数据,跟踪引擎应用算法来自动识别那些值得特殊处理以便快速访问的数据对象(例如,用于放置在用户容易访问的“搁板”或其他结构中)。 启发式学习模块可以基于使用数据生成数据对象排名,并将该排名传达到使用跟踪引擎,以确定数据对象在“架子”上的放置资格。 这种排名可以考虑个性化设置,和/或用户过去的手动搁置数据对象的放置。

    • An adaptive capacitive touch sense control circuit includes a voltage buffer, a current setting resistor, a current mirror, a capacitor, a start comparator, an end comparator and a time-to-digital converter. The capacitor is connected with the current setting resistor. The circuit further includes a latch with a first control switch and a second control switch. The current setting resistor is switched between the ground and a voltage source through a switching element, so that when the current setting resistor is grounded, the first control switch is closed and the second control switch is opened, and when the current setting resistor is connected with the voltage source, the second control switch is closed and the first control switch is opened. An adaptive charging mode is adopted to sense a capacitance variation with a great ability of interference recognition, a simple structure, low power consumption and real time processing.
