Abstract: A dual power switch system and the related control method thereof. The dual power switch system includes: a power supply module for supplying power to the dual power switch system; a first power switch circuit, electrically connected to the power supply module, for generating a first control voltage to trigger the power supply module to supply the power; and a second power switch circuit, electrically connected to the power supply module, for generating a second control voltage through magnetic induction to trigger the power supply module to supply the power.

Abstract: The invention provides a mode switching method in a digital image acquisition apparatus with a first button for taking pictures and a second button for mode switching. Snapshot modes and a viewing mode are provided. A snapshot parameter is for recording whether the apparatus is currently used for taking pictures. Each time when the apparatus is used for taking pictures via the first button, the snapshot parameter is recorded as a snapshot status. A mode parameter is for recording which mode the apparatus is currently situated. Each time when the apparatus is used for mode switching via the second button, the mode parameter is recorded as a corresponding mode status. When the apparatus performs mode switching via the second button, if the snapshot parameter is at the same time recorded as the snapshot status, the apparatus is switched directly to the viewing mode in irrespective to its original snapshot mode.

Abstract: An input detection device contains a button set having a plurality of buttons utilized for inputting commands, each button outputting a unique voltage level when the button is activated. The input detection device also contains a voltage generating circuit for outputting a plurality of generated voltage levels corresponding to the unique voltage levels outputted by each of the buttons in the button set, and a comparator for comparing each of the generated voltage levels outputted from the voltage generating circuit with the voltage outputted from the button set. A control circuit controls the voltage generating circuit to alternately output each of the generated voltage levels, records the generated voltage level that is approximately equal to the voltage outputted from the button set, and determines which button in the button set was activated based on the recorded generated voltage level.

Abstract: An image capturing apparatus with proximity sensing function includes a lens for receiving an image, a focusing module for focusing the image by the lens, an optical sensing device, a shutter for exposing the focused image for a time period, which the focused image is captured by the optical sensing device through the lens, and a first proximity sensor for outputting a first control signal to activate the shutter when the first proximity sensor being activated.
