System and method for tracking inventory movement using a material handling device
First Claim
1. A method of tracking inventory using a material handling device that utilizes a lift mechanism provided on the material handling device for use in transporting an inventory unit from one location to a different location, the method comprising:
- moving the lift mechanism using a hydraulic system;
generating a signal indicative of hydraulic pressure within a hydraulic line of the hydraulic system; and
obtaining item information upon a change in the hydraulic pressure beyond a predetermined threshold value using a reader carried by the material handling device.

Abstract
A method of tracking inventory using a material handling device that utilizes a lift mechanism provided on the material handling device for use in transporting an inventory unit from one location to a different location is provided. The method includes moving the lift mechanism using a hydraulic system and generating a signal indicative of hydraulic pressure within a hydraulic line of the hydraulic system. Item information is obtained upon a change in the hydraulic pressure beyond a predetermined threshold value using a reader carried by the material handling device.

27. A method of detecting a load event of a material handling device that utilizes a hydraulically controlled lift mechanism provided on the material handling device for use in transporting an inventory unit from one location to a different location, the method comprising:
-
detecting a cargo pick up or cargo put down event by monitoring hydraulic pressure in a hydraulic system using a pressure transducer outputting a signal indicative of hydraulic pressure, the hydraulic system used to move the lift mechanism between positions; and verifying occurrence of the cargo pick up or cargo put down event by detecting movement of the lift mechanism using a position detector outputting a signal indicative of movement of the lift mechanism off of a retracted position and detecting position of a control lever using a detector outputting a signal indicative of a position of the control lever, the control lever providing operator control of movement of the lift mechanism.

28. A material handling device capable of detecting a load event, the material handling device comprising:
-
a lift mechanism; a lift control that provides operator control of movement of the lift mechanism; a sensor capable of generating a signal indicative of an operating condition of the lift mechanism; a reader configured to obtain information from a transponder using a reader antenna during a reading operation; and a processor connected to the sensor for use in detecting the load event; wherein the processor receives the signal from the sensor and initiates the reading operation when a load event is detected.
