Abstract: A method and system for estimating the weight of a seat occupant. In one embodiment, the system includes a linkage having one or more links; an actuator; a pivot driveably coupled between the links and the actuator; and a sensor coupled to the pivot and operable to sense a load at the pivot, where the sensed signal is processed to provide an output signal representative of seat occupant weight. The system provides weight estimation with reduced sensitivity to horizontal loads and may be implemented with seats having a fixed height or a plurality of powered and manual seat height adjustment mechanisms.

Abstract: A software application has certain keyboard hot key combinations. If the application is active the pressing of a key is detected for the application. A number of keyboard keys are selected responsive to the key pressed. The selected keys correspond to hot key combinations that include the pressed key. The keyboard is signaled to differentiate the selected keys. Further, the application is operable to have a number of contexts, where certain ones of the hot key combinations are only valid for certain of the contexts. For example, where the application includes a word processing function one of the application contexts is a circumstance in which text is selected. Accordingly, the method includes detecting the context of the application and the selecting is responsive to that context. In this situation the selected keys correspond to hot key combinations that include the pressed key and that are valid for the detected context.
