1. A data collection device (DCD), comprising:
- a main body having a front and a back;
at least one data input device on the main body for receiving user input;
at least one display on the front of the main body;
an accelerometer within the main body for detecting movement and the orientation of the DCD; and
a processor within the main body configured for;
determining if the DCD is front down or back down;
if the DCD is front down, placing the DCD in a first sleep state and then a second sleep state based on the time elapsed without detecting movement of the DCD or receiving input since the DCD was placed in the first lower power mode; and
if the DCD is back down, placing the DCD in the second sleep state and then a third sleep state based on the time elapsed without detecting movement of the DCD or receiving input since the DCD was placed in the second lower power mode.

Abstract
A data collection device (DCD) is placed in a first low power mode after the DCD has been in a first predetermined position, and placed in a second low power mode after a first predetermined period of time. In another embodiment the DCD includes a wireless telephone, and a proximity sensor which detects when the DCD is close to a user'"'"'s face, wherein the telephone is automatically put in a handset mode when the DCD is close to a user'"'"'s face, and automatically put in a speakerphone mode when the DCD is not close to a user'"'"'s face.

11. A data collection device (DCD), comprising:
-
a main body having a front and a back; at least one data input device on the main body for receiving user input; at least one display on the front of the main body; a proximity sensor within the main body for detecting the DCD'"'"'s proximity to other objects; an accelerometer within the main body for detecting movement and the orientation of the DCD; and a processor within the main body configured for; determining if the DCD is front down, back down, or neither front down nor back down; if the DCD is front down, placing the DCD in a first sleep state and then a second sleep state based on the time elapsed without detecting movement of the DCD or receiving input since the DCD was placed in the first lower power mode; if the DCD is back down, placing the DCD in the second sleep state and then a third sleep state based on the time elapsed without detecting movement of the DCD or receiving input since the DCD was placed in the second lower power mode; and if the DCD is neither front down nor back down, placing the DCD in the third sleep state and then a fourth sleep state based on the time elapsed without detecting movement of the DCD or receiving input since the DCD was placed in the third lower power mode. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A data collection device (DCD), comprising:
-
a main body having a front and a back; a touch panel on the main body for receiving user input; a data input device on the main body for receiving user input; a display on the front of the main body; a proximity sensor within the main body for detecting the DCD'"'"'s proximity to other objects; an accelerometer within the main body for detecting movement and the orientation of the DCD; and a processor within the main body configured for; determining if the DCD is front down or back down; if the DCD is front down, placing the DCD in a first sleep state and then a second sleep state based on the time elapsed without detecting movement of the DCD or receiving input since the DCD was placed in the first lower power mode; if the DCD is back down, placing the DCD in the second sleep state and then a third sleep state based on the time elapsed without detecting movement of the DCD or receiving input since the DCD was placed in the second lower power mode; placing the DCD in a reduced power state in response to detecting, with the proximity sensor, that the DCD is close to a user'"'"'s face; turning off the display and the touch panel when placing the DCD in the first sleep state; and inactivating more DCD functions in the third sleep state than in the first sleep state. - View Dependent Claims (22, 23, 24)
