Keypad with audit trail for high density mobile systems
First Claim
1. A control device for a mobile storage system having a plurality of storage units at least one of the storage units selectively allowed to move toward and away from another of the storage units comprising:
- a data entry portion on which an access code is entered;
a display device configured to display messages and show the status of the mobile storage system;
a real time clock containing time and date information;
a memory device configured to store a data table containing at least one access code associated with a set of access rights; and
a processor executing a program wherein;
the access code entered is compared against the access codes stored in the data table to identify whether a matching access code is present in the data table;
the access rights associated with the matching access code are read from the memory device;
the mobile storage units are selectively controlled to selectively permit and deny access to an aisle between one or more of the plurality of storage units according to the access rights read from the memory device; and
an activity log stores the access code in the memory device;
wherein a housing is mounted on the at least one of the storage units and commonly integrates the data entry portion, the display device, the real time clock, the memory device and the processor therein, such that a user of the control device is enabled to enter the access code and monitor the status of the mobile storage system independent of any data entry portion or display device located remote from the at least one of the storage units.

Abstract
A control device for a mobile storage system includes a data entry device, such as a numeric keypad. The user enters an access code on the keypad, and the access code is compared against a data table including a list of security levels associated with access codes. If the access code entered is included in the data table, the user is permitted to control the mobile storage system according to the access rights granted by the security level associated with the access code. Each of the access codes and attempted commands entered in the numeric keypad are recorded in an activity log. The activity log is downloadable to a computer for later review.

11. In a mobile storage system having a plurality of storage units at least one of the storage units selectively allowed to move toward and away from another of the storage units comprising, a control device comprising:
-
a data entry portion having input devices on which an access code is entered; a display device configured to display messages and show the status of the mobile storage system; a real time clock containing time and date information; a memory device configured to store a data table containing at least one access code each access code associated with a set of access rights; and a processor executing a program wherein; the access code entered is compared against the access codes stored in the data table to identify whether a matching access code is present in the data table; the access rights associated with the matching access code are read from the memory device; the mobile storage units are selectively controlled to selectively permit and deny access to an aisle between one or more of the plurality of storage units according to the access rights read from the memory device; an activity log stores the access code in the memory device; and the control device is configured such that none, some or all of the input devices require an access code to operate, wherein a housing is mounted on the at least one of the storage units and commonly integrates the data entry portion, the display device, the real time clock, the memory device and the processor therein such that a user of the control device is enabled to enter the access code and monitor the status of the mobile storage system independent of any data entry portion or display device located remote from the at least one of the storage units. - View Dependent Claims (12, 13, 14)

15. A method of controlling a mobile storage system having a plurality of storage units at least one of the storage units selectively allowed to move toward and away from another of the storage units, the steps comprising:
-
entering an access code on a data entry portion having input devices configured such that none, some or all of the input devices require an access code to operate; providing a memory device and a processor to compare the access code entered to a stored data table containing at least one access code; identifying the set of access rights associated with an access code that matches the access number; allowing the mobile storage units to be selectively controlled to selectively permit and deny access to an aisle between one or more of the plurality of storage units using a real time clock according to the access rights of the matching access code; storing each access code entered in an activity log; and providing a display device to display messages and show the status of the mobile storage system, wherein a housing of a control device is mounted on the at least one of the storage units and commonly integrates the data entry portion, the display device, the real time clock, the memory device and the processor therein, such that a user of the control device is enabled to enter the access code and monitor the status of the mobile storage system independent of any data entry portion or display device located remote from the at least one of the storage units. - View Dependent Claims (16, 17)
