Abstract:
Disclosed herein is a method and system for determining a billing structure for outputting documents using an image processing apparatus. If image data of the document includes color pixels, a billing structure is determined based on an estimated total color pixel count. The color pixels of the image data are counted in a device independent space and the total color pixel count of the image data to be output in a device dependent space is estimated. Based on the estimation, a billing structure is chosen. Processing and determining a billing structure based on image data in the device independent space avoids charging a customer for color print job when only a small amount of color pixels are printed. It also encourages determining charges independently of the marking engine or output device.

Abstract:
An apparatus (10) and method for sensing a vehicle crash condition includes a transponder (76a) responsive to interrogation signals for providing response signals and a transceiver (70a) for transmitting interrogation signals to the transponder (76a) and receiving response signals from the transponder (76a). The transponder (76a) is affixed to a first structure (36) of the vehicle (12) and the transceiver (70a) is affixed to a second structure (64) of the vehicle (12) at a location spaced apart from the first structure (36). A characteristic of the response signals changes in response to a vehicle crash condition that causes relative movement between the first and second structures (36 and 64). The apparatus (10) also includes a controller (34) for monitoring the received response signals to determine whether a vehicle crash condition is occurring.
