Abstract: A label modification unit may receive a label modification input that indicates a label modification associated with content being written to a label or erased from the label. The label modification unit may identify an area of the label that is associated with the label modification according to the label modification input. The label modification unit may determine, based on a size of the area, a spot size of a light beam that is configured to be emitted by a laser printhead to modify the content within the area. The label modification unit may determine, based on the spot size and the content, an optical path configuration for the laser printhead. The label modification unit may operate the laser printhead according to the optical path configuration to write the content to the area or erase the content from the area.

Abstract: A system, method and computer program product for providing a gesture-based interface on a wireless device (102). The method on a wireless device (102) includes detecting a movement from a user by a motion detector and accelerometer (104) that is integrally located in the wireless device (102) or located externally to the wireless device (102) and coupled to the wireless device (102). The method further includes providing user input to a user interface of the wireless device (102) in response to the detecting the movement. The user input includes navigating selections in the user interface of the wireless device (102), such as moving between pages displaying a list of selections and scrolling through a list of selections. The user input further includes activating selections in the user interface of the wireless device (102), such as initiating or answering a wireless telephone call and sending or receiving a wireless message.
