Abstract: A backup power supply apparatus includes at a light source absorbing device which consists of at least one light source absorbing element. The light source absorbing element is pivotally engaged with each other and is foldable for housing inside a casing to facilitate carrying outdoors for use. The light source absorbing element may be unfolded to absorb light source to generate electric power output required by a load.

Abstract: A hand-writing input and recording device is housed in a case and may be hand-held by a user when in use. The device includes a contact element, an amplifying element, a sense element, an X-Y axes matrix element, a recording and storing element, a transmitting element and a receiving element. When the contact element generates a displacement variation in the X-Y axes, the X-Y axes displacement variation value will be emitted from the transmitting element to the receiving element and input into a computer for display on a computer screen to show the characters or patterns generated from the X-Y axes displacement variation value.
