Patent ID: 7549583

Claim:
A method of providing a wake up feature to an in-counter bar code scanner allowing a user to wake up the bar code scanner from its power-saving standby mode comprising: attaching an oscillating magnet member to a portion of the bar code scanner, the oscillating magnet member comprising a base and a permanent magnet attached to the base by a flexible member extending between the base and the permanent magnet, wherein base of the oscillating magnet member gets attached to said portion of the bar code scanner; and attaching a pick-up coil to said portion of the bar code scanner at a magnetically effective distance from the permanent magnet, wherein when a user touches said portion of the bar code scanner an impact force exerted on the bar code scanner is transmitted to the oscillating magnet member causing the permanent magnet to oscillate inducing an electrical signal in the pick-up coil for waking up the bar code scanner from its standby mode, wherein said portion of the bar code scanner is a scanning surface having an exterior surface exposed to the user and an interior surface, and the base of the oscillating magnet member is attached to the interior surface of the scanning surface.
