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.
Claims8
A data collection device (DCD), comprising a motion sensor, a proximity detector, a keypad, a memory, a processor in communications with the memory, and a phone, wherein the DCD is configured to perform a method comprising:
- placing the DCD in a first low power mode responsive to the DCD being front down for a first predetermined period of time;
- placing the DCD in the first low power mode in a second low power mode responsive to the DCD being back down for a second predetermined period, wherein the second predetermined period of time is longer than the first predetermined period of time;
- placing the DCD in the second power mode in a third low power mode responsive to the DCD being in a position that is neither front down nor back down for a third predetermined period of time, wherein the third predetermined period of time is longer than the second predetermined period of time;
- and placing the DCD in one of the first power mode, the second power mode, or the third power mode in a reduced power state when the proximity detector detects the DCD is close to a user's face, wherein said reduced power states comprises a speakerphone or hands free mode.
A method for managing power in a data collection device (DCD), wherein the DCD comprises a motion sensor, a proximity detector, a keypad, and a phone, the method comprising:
- placing the DCD in a first low power mode responsive to the DCD being front down for a first predetermined period of time;
- placing the DCD in the first low power mode in a second low power mode responsive to the DCD being back down for a second predetermined period, wherein the second predetermined period of time is longer than the first predetermined period of time;
- placing the DCD in the second power mode in a third low power mode responsive to the DCD being in a position that is neither front down nor back down for a third predetermined period of time, wherein the third predetermined period of time is longer than the second predetermined period of time;
- and placing the DCD in one of the first power mode, the second power mode, or the third power mode in a reduced power state when the proximity detector detects the DCD is close to a user's face, wherein said reduced power states comprises a speakerphone or hands free mode.
