Abstract: A sample and hold circuit and the method thereof are disclosed. The sample and hold circuit may be applied in voltage regulators or other circuits. The sample and hold circuit comprises: an input terminal configured to receive an input signal; an output terminal configured to provide an output signal; a control circuit configured to receive the input signal and the output signal, and wherein based on the input signal and the output signal, the control circuit generates a digital signal, and wherein the digital signal increases when the output signal is lower than the input signal, and maintains when the output signal is larger than or equal to the input signal; a digital-to-analog converter (DAC) configured to convert the digital signal to the output signal.

Abstract: In order to unload/reload ladders from/onto a vehicle's roof without physical power needed, a hydraulic driven ladder rack system has been designed which includes: a chassis mounted on vehicle's roof; a hydraulic driver and a pivotal arm are pivotally coupled on front and rear end of chassis separately. a movable ladder rack engaged with two rolls which installed on top of rear ladder rack supporter; pivotal arm pivotally coupled to front area of ladder rack, hydraulic shaft pivotally coupled to middle of pivotal arm. When hydraulic shaft push out, pivotal arm pivots up and push ladder rack moving upward and backward, until ladder rack arrived generally vertical position in back of vehicle. At this position ladders unload/reload, from/onto ladder rack. When hydraulic shaft draw back, pivotal arm pulls back ladder rack to horizontal position on vehicle's roof. These operations are completed automatically.

Abstract: In order to save physical power and avoid using manual operative mechanism for unload/reload ladders from/onto a vehicle roof, a electric motor driven ladder rack system has been designed which includes: a fixed guide which is mounted on a vehicle roof; a pivotal guide that is pivotally coupled to the fixed guide; a driving box and a sliding ladder rack which is linked to the driving box by chain and engaged with the pivotal guide. Under acting force of motor and gravity the ladder rack moves sliding backward and pivoting downward from the horizontal position on the vehicle roof to a generally vertical position behind the vehicle at which the ladders can be unloaded/loaded. In an opposite process the ladder rack is pulled back on the vehicle roof. In these processes there is no physical power needed at all.
