Abstract: An inspection compliance validation system for a truck includes a plurality of indicators and a reader. Each indicator is coupled to a vehicle proximate to a respective inspection site of the vehicle and is operationally coupled to an electronic logging device of the vehicle. The electronic logging device is positioned to selectively actuate the indicator to notify a user of an inspection status for an associated inspection site. The reader is configured to receive a signal from a respective indicator corresponding to the inspection status of the associated inspection site and to relay the signal to the electronic logging device to validate that an inspection has been performed.

Abstract: Online purchasing of components compatible with particular hardware devices of a computer system. In one aspect, the identity of a hardware device capable of communicating with computer systems is automatically determined. At least one component for the hardware device is displayed on a computer system based on the identity of the hardware device such that the user can select the at least one component for purchase, where the at least one component is compatible with and for use with the hardware device.

Abstract: Presenting system and device conditions and purchasing options for components compatible with hardware devices of a computer system. In one aspect, an operating system determines the identity of a hardware device in communication with the operating system, communicates over a network to receive current purchasing information related to the hardware device, and displays components that can be selected for purchase and used with the hardware device. Another aspect provides a selectable user interface control for display in a graphical user interface that indicates a new operating condition of the computer system, different from a prior operating condition, by displaying a different appearance of the control. One embodiment has a new operating condition occurring when a component of a hardware device is within a predetermined threshold of requiring replacement, refilling, or supplementation.
