Scanner with wake-up mode

Abstract

An indicia reader system includes an indicia reader provided at a point of transaction; a controller for controlling power to the indicia reader; a detector for detecting a customer, item or shopping cart at the point of transaction and providing an indication signal to the controller of the presence of customer, item or shopping cart at the point of transaction; wherein the controller interrupts power to the indicia reader during a power save mode and resumes power to the indicia reader upon receiving the indication signal.

1 . An indicia reader system comprising:
 an indicia reader provided at a point of transaction;   a controller for controlling power to the indicia reader; and   a detector for detecting a customer, item or shopping cart at the point of transaction and providing an indication signal to the controller of the presence of customer, item or shopping cart at the point of transaction;   wherein the controller interrupts power to the indicia reader during a power save mode and resumes power to the indicia reader upon receiving the indication signal.   
     
     
         2 . The system of  claim 1 , wherein the detector comprises a vibration detector. 
     
     
         3 . The system of  claim 1 , wherein the detector detects weight. 
     
     
         4 . The system of  claim 1 , wherein the detector detects movement. 
     
     
         5 . The system of  claim 1 , wherein the detector detects voltage on a conveyor utilized for moving items towards the indicia reader. 
     
     
         6 . The system of  claim 1 , wherein the detector comprises an infrared detector disposed on a side of the scanner facing the customer. 
     
     
         7 . The system of  claim 1 , wherein the detector comprises an infrared detector disposed at the entrance of a point of transaction checkout lane. 
     
     
         8 . A method of operating an indicia reader system, comprising:
 providing an indicia reader at a point of transaction;   controlling power to the indicia reader to interrupt power to the indicia reader;   detecting a customer, item, or shopping cart at the point of transaction and providing an indication signal to the controller of the presence of the customer, item or shopping cart at the point of transaction; and   resuming power to the indicia reader upon the controller receiving the indication signal.   
     
     
         9 . The method of  claim 8 , wherein the detector comprises a vibration detector. 
     
     
         10 . The method of  claim 8 , wherein the detector detects weight. 
     
     
         11 . The method of  claim 8 , wherein the detector detects movement. 
     
     
         12 . The method of  claim 8 , wherein the detector detects voltage on a conveyor utilized for moving items towards the indicia reader. 
     
     
         13 . The method of  claim 8 , wherein the detector comprises an infrared detector disposed on a side of the scanner facing the customer. 
     
     
         14 . The method of  claim 8 , wherein the detector comprises an infrared detector disposed at the entrance of a point of transaction checkout lane. 
     
     
         15 . An indicia reader system comprising:
 an indicia reader provided at a point of transaction;   a controller for controlling power to the indicia reader;   a first detector for detecting a customer, item or shopping cart at the point of transaction and providing an indication signal to the controller of the presence of customer, item or shopping cart at the point of transaction; and   a second detector for sensing items on the bottom of a shopping cart and providing an indication signal in response to the existence of items on the bottom of the cart;   wherein the controller interrupts power to the indicia reader during a power save mode and resumes power to the indicia reader upon receiving the indication signal.   
     
     
         16 . The system of  claim 15 , wherein the first detector comprises a vibration detector. 
     
     
         17 . The system of  claim 15 , wherein the first detector detects weight. 
     
     
         18 . The system of  claim 15 , wherein the first detector detects movement. 
     
     
         19 . The system of  claim 15 , wherein the first detector comprises an infrared detector disposed on a side of the scanner facing the customer. 
     
     
         20 . The system of  claim 15 , wherein the first detector comprises an infrared detector disposed at the entrance of a point of transaction checkout lane.
