Abstract: Sensor data produced in a multi-sensor environment is time synchronized, such as using a master time. A component that derives the master time transmits a signal to a first sensor of the multi-sensor environment, which signal indicates the master time. The component subsequently receives a signal from the first sensor, which signal indicates a first time determined by the first sensor based on the master time and a latency associated with the first sensor. The first time indicates a time of an event associated with the first sensor data. A determination is then made that the first sensor data corresponds to second sensor data produced using a second sensor of the multi-sensor environment based on the first time and a second time indicating a time of an event associated with the second sensor data.

Abstract: Backlit LCD displays are becoming commonplace within many vehicle applications. The unique advantage of this invention is that it optimizes system power savings for display of low dynamic range (LDR) images by dynamically controlling spatially adjustable backlighting. This is accomplishes through use of a control technique that takes into account the sequential nature of the video display process.
