摘要： An ambient light sensor produces a current signal that varies linearly with the level of ambient light. The current signal is multiplied by a user dimming preference to generate a brightness control signal that automatically compensates for ambient light variations in visual information display systems. The multiplying function provides noticeable user dimming control at relatively high ambient light levels.

摘要： A battery charger for an electronic device receives current limited power from an external power source, such as a Universal Serial Bus power interface. The battery charger can linearly regulate a charging current to an internal battery and limit the charging current so as not to demand current in excess of what the external power source can provide. A bi-directional pass element coupled between a system power terminal and the internal battery controls the charging current and effectively isolates the internal battery from a system load during charging of the battery while providing a low impedance path from the internal battery to the system load during discharging of the battery.

摘要： The present invention is a method and apparatus for providing a power supply system having a redundant power supply switchover circuit, which maintains a remotely regulated output voltage when the power supply system switches over from the primary power supply to the secondary power supply. The power supply system comprises a secondary power supply that is connected in parallel to a primary power supply. The two power supplies are OR-connected to a load through two diodes, with the primary power supply connected to the diode via a monitor. During normal operating conditions, the primary power supply delivers most of the current because it operates in a "remote sense" configuration which provides a voltage output that is higher, by a diode voltage drop, than that of the secondary power supply, which operates in a "local sense" configuration. When a monitor detects the failure of the primary power supply, it generates a control signal to direct a relay switch to switch the secondary power supply from the "local sense" configuration to the "remote sense" configuration. As a result, the secondary power supply will deliver the full power requirements of the load. During the momentary switchover period, fluctuations in load voltage are minimal and within the range permitted by most logic devices.
摘要翻译：本发明是一种用于提供具有冗余电源切换电路的电源系统的方法和装置，其在电源系统从主电源切换到次电源时保持远程调节的输出电压。电源系统包括与主电源并联连接的二次电源。两个电源通过两个二极管OR连接到负载，主电源通过监视器连接到二极管。在正常工作条件下，主电源提供大部分电流，因为它以“远程感应”配置运行，该配置通过二极管压降提供的电压输出比二次电压降高 “本地感”配置。当监视器检测到主电源故障时，它产生一个控制信号以指示继电器开关将次级电源从“本地检测”配置切换到“远程感应”配置。因此，二次电源将提供负载的全部功率要求。在瞬间切换期间，负载电压的波动很小，并且在大多数逻辑器件允许的范围内。

摘要： An illumination control circuit allows a user to set a desired brightness level and maintains the desired brightness level over temperature and life of a light source. The illumination control circuit uses a dual feedback loop with both optical and thermal feedbacks. The optical feedback loop controls power to the light source during normal operations. The thermal feedback loop overrides the optical feedback loop when the temperature of the light source becomes excessive.
