Abstract: A mobile device and an article of manufacture as implemented in a mobile device having a lock screen wallpaper is described, where the mobile device maintains a profile storing authentication data associated with a primary user of a mobile device that is authorized to use the mobile device. When the mobile device is at a business location, the primary user is non-intrusively authenticated as an authorized user of the mobile device based on identifying presence of another electronic device (e.g., another mobile device) associated with the primary user. Upon successful authentication a scanning code is displayed over a lock screen wallpaper of the mobile device, where power is conserved in the mobile device by providing the scanning code to the primary user without unlocking the mobile device.

Abstract: A navigation application running in the foreground of the mobile device is run in the background when the mobile device enters a screen locked state. A display may be activated while the mobile device remains in the screen locked state, and an image is rendered over a lock screen of the mobile device, where the image providing a glimpse into the navigation application running in the background while the mobile device remains in the screen locked state. The image displayed over the lock screen is iteratively updated to provide a continuous glimpse into the navigation application running in the background of the mobile device that is in the screen locked state, without having to unlock the mobile device.

Abstract: Disclosed is a height and rotational adjustment system for a spray gun used in a line striper comprising: (a) a control device to set a dimension of a line to be sprayed and set an angle at which the line is to be sprayed; (b) a spray gun mount bar having a gun holder assembly to retain a spray gun; (c) a height adjustment mechanism coupled to the spray gun mount bar; (d) an angular adjustment mechanism coupled to the spray gun mount bar; and wherein the control device transmits signals (e.g., wirelessly) to: (1) the height adjustment mechanism to raise or lower the spray gun mount bar to spray the line with the dimension in (a), and (2) the angular adjustment mechanism to rotate, in a clockwise or counter-clockwise manner, the spray gun mount bar to spray the line at the angle in (a).

Abstract: An effective implementation is shown for a height adjustment system for a plurality of spray guns used in a line striper.

Upon successful authentication a scanning code is displayed over a lock screen wallpaper of the mobile device, where power is conserved in the mobile device by providing the scanning code to the primary user without unlocking the mobile device.

Abstract: A profile is maintained in a mobile device for storing authentication data associated with a primary user of a mobile device, and at least one secondary user that is authorized to use the mobile device. When the mobile device is at a business location, the secondary user is passively authenticated, and upon successful authentication: an image is displayed over a default lock screen wallpaper when the mobile device is in a screen locked state, wherein the image contains a scanning code, and a financial transaction is facilitated at the business location based on the scanning code without unlocking the mobile device, wherein the financial transaction associated with a financial account of the primary user. Power is conserved in the mobile device by not unlocking it at the business location to conduct the financial transaction.

Abstract: Disclosed within are various methods for adjusting height and rotation of a spray gun used in a line striper via a graphical user interface (GUI) in a control device.

Abstract: An article of manufacture is described as implemented in a mobile device having a lock screen wallpaper, where the mobile device maintains a profile storing authentication data associated with both a primary user of a mobile device and one or more secondary users that are authorized to use the mobile device. When the mobile device is at a business location, the secondary user(s) are non-intrusively authenticated as authorized user(s) of the mobile device. Upon successful authentication a scanning code is displayed over a lock screen wallpaper of the mobile device, where power is conserved in the mobile device by providing the scanning code to the secondary user(s) without unlocking the mobile device.
