    • A system, method, and program product is provided that configures video handlers pertaining to a dependent individual. Configuring includes setting alert thresholds. Visual locations are configured. Visual images that pertain to caregivers of the dependent individual are configured. Video streams are received from video sources. Video streams are compared to configured locations to classify the dependent individual's location. Video stream is analyzed to determine whether the dependent individual is alone or with others. If with others, a list of known persons is determined by comparing the video streams with the configured visual images. The configured video handlers are initiated based on the inputs of the location and the people present with the dependent individual. Video handlers trigger alerts when thresholds are reached. Alerts include performing actions to protect the dependent individual from harm.

    • A switched mode converter is disclosed that includes mode logic for switching between voltage mode and current mode. The converter includes sensing circuitry for sensing current on the primary side, load current on the secondary side, and converter output voltage. When load current is less than a predetermined value, the converter operates in voltage mode wherein output voltage of the voltage mode controller is used to control the duty cycle of a PWM controller. When load current is greater than a predetermined value, the converter operates in current mode wherein primary current is used to control the PWM controller. Thus during a light load when the converter is voltage controlled there is no need for a minimum load to stabilize the control loop. In current-mode the control loop will have faster transient response and avoid flux imbalance. Thereby providing advantages of both voltage and current controlled switched mode converters.
    • 公开了一种开关模式转换器,其包括用于在电压模式和电流模式之间切换的模式逻辑。 该转换器包括用于检测初级侧的电流,次级侧的负载电流和转换器输出电压的感测电路。 当负载电流小于预定值时,转换器工作在电压模式,其中电压模式控制器的输出电压用于控制PWM控制器的占空比。 当负载电流大于预定值时,转换器以当前模式工作,其中初级电流用于控制PWM控制器。 因此,在转换器受电压控制的轻负载期间,不需要最小负载来稳定控制回路。 在电流模式下,控制回路具有更快的瞬态响应,避免通量不平衡,从而提供电压和电流控制的开关模式转换器的优势。
