Depowered standby paper shredder and method
First Claim
1. A shredder for comminuting shreddant, comprising:
- motorized shredder blades to comminute shreddant when activated;
a motor controller coupled to the motorized shredder blades;
a shredder controller coupled to the motor controller;
a timer coupled to the motor controller, wherein the timer is activated over a predetermined active period; and
a mechanically-actuated switch (GREEN SWITCH) coupled to the shredder controller, disposed in a paper feed inlet opening throat and covering at least a part of the inlet opening throat,wherein the GREEN SWITCH while actuated by inserting shreddant into the inlet opening throat causes the shredder controller, the motor controller, and the motorized shredder blades, to be activated, wherein shreddant is comminuted while motorized shredder blades are activated,wherein the GREEN SWITCH causes the motorized shredder blades to become deactivated when the GREEN SWITCH is deactuated by no shreddant being in the inlet opening throat, wherein the GREEN SWITCH, when first deactuated activates the timer, andwherein the timer causes power to be removed from the shredder controller, the motor controller, and the motorized shredder blades upon expiration of the predetermined active period.

Abstract
Apparatus and method for a power-saving shredder, including motorized shredder blades; a shredder controller coupled to the motor controller; a timer coupled to the motor controller, and a mechanically-actuated switch (GREEN SWITCH) couples to the shredder controller. The GREEN SWITCH causes the shredder controller, the motor controller, the motorized shredder blades, and the timer to be activated. The Normally Off switch, when deactuated, causes motorized shredder blades to deactivate. A method of operating a paper shredder includes operating a mechanical actuation switch ON; applying power to paper shredder electrical and electronic elements by operating the mechanical actuation switch; setting a timer for a predetermined active period; operating motorized paper shredder blades by operating the mechanical actuation switch ON; operating the mechanical actuation switch OFF; counting by the timer the predetermined active period; and if the predetermined active period has expired, removing power from the paper shredder electrical and electronic elements.

7. A shredder for comminuting shreddant, comprising:
-
motorized shredder blades to comminute shreddant when activated; a motor controller coupled to the motorized shredder blades; a shredder controller coupled to the motor controller, including a timer coupled therein, wherein the timer is activated over a predetermined active period; a power enable/disable (PED) switch to provide electric power to the motorized shredder blades, the motor controller, and the shredder controller when in the power enabled state; and a mechanically-actuated switch (GREEN SWITCH) coupled to the shredder controller, wherein the GREEN SWITCH while actuated by shreddant in a throat of the shredder causes the shredder controller, the motor controller, and the motorized shredder blades to be activated, wherein when the GREEN SWITCH is deactuated by no shreddant in the throat causes the motorized shredder blades to become deactivated and the timer to be activated for a predetermined active period, and wherein upon expiration of the predetermined active period the timer causes power to be removed from the shredder controller, the motor controller, and the motorized shredder blades. - View Dependent Claims (8, 9)
