A method and apparatus for determining quantization error in data is disclosed. The method comprises gathering a plurality of data points, identifying a range of the data points, separating the data points into a plurality of segments, and estimating the quantization error by calculating the ratio between the data range and the quantity of segments. The apparatus comprises means for gathering a plurality of data points, means for identifying a range of the data points, means for separating the data points into a plurality of segments, and means estimating the quantization error by calculating the ratio between the range and the quantity of the segments.

A method and apparatus are provided for filling a gap of missing data using source specified data. The method includes analyzing a first set of data representative of utility consumption for a plurality of days to determine clusters of days of the week having similar utility consumption. The method further includes generating an individual profile of utility consumption for each cluster, and copying data from at least one individual profile into the gap to form a second set of data without any gaps. A system for filling a gap of missing data using source specified data includes a microprocessor programmed to copy data from at least one individual profile into the gap, and to adjust the copied data up or down to account for local trend information adjacent to the gap.

A voice-operated, interactive message display system designed for inter-vehicle and extra-vehicle communications. The system includes one or more display units having a matrix of light-emitting elements to transmit a message to other vehicles either to the front, rear, side, or combination thereof. The display units are controlled by a central control unit having a voice recognition and voice synthesis system, which is used to interactively determine a message to display and on which displays to present it. Upon manual activation, the message system vocally prompts the user for the message to display and the parameters for its display. The system may be implemented in at least two different embodiments. In one embodiment a powerful vocabulary memory unit is used and the content of the message is run-time programmable. If a less expensive vocabulary unit is used, the user may choose from a series of preprogrammed messages. Once specified, the message can then be delivered to the displays (front, rear, or side) in normal or mirror imaged formats. The display system can also monitor ambient light conditions to make appropriate brightness and contrast adjustments to maximize message readability.
