An on-board intelligent vehicle system includes a sensor assembly to collect data and a processor to process the data to determine the occurrence of at least one event. The data may be collected from existing standard equipment such as the vehicle communication bus or add-on sensors. The data may be indicative of conditions relating to the vehicle, roadway infrastructure, and roadway utilization, such as vehicle performance, roadway design, roadway conditions, and traffic levels. The detection of an event may signify abnormal, substandard, or unacceptable conditions prevailing in the roadway, vehicle, or traffic. The vehicle transmits an event indicator and correlated vehicle location data to a central facility for further management of the information. The central facility sends communications reflecting event occurrence to various relevant or interested users. The user population can include other vehicle subscribers (e.g., to provide rerouting data based on location-relevant roadway or traffic events), roadway maintenance crews, vehicle manufacturers, and governmental agencies (e.g., transportation authorities, law enforcement, and legislative bodies).

The invention provides systems for integrated haptic design and fabrication of dental restorations that provide significant advantages over traditional practice and existing computer-based systems. The systems feature technical advances that result in significantly more streamlined, versatile, and efficient design and fabrication of dental restorations. Among these technical advances are the introduction of voxel-based models; the use of a combination of geometric representations such as voxels and NURBS representations; the automatic identification of an initial preparation (prep) line and an initial path of insertion; the ability of a user to intuitively, haptically adjust the initial prep line and/or the initial path of insertion; the automatic identification of occlusions and draft angle conflicts (e.g., undercuts); the haptic simulation and/or marking of occlusions and draft angle conflicts; and coordination between design output and rapid prototyping/milling and/or investment casting.

A biometric access control and time and attendance system comprises an integrated network including one or more remote access devices in electronic communication with a computer database. Each remote access device comprises a silicon chip based system and preferably includes a biometric input device, a liquid crystal display (LCD), computer processing capabilities based on embedded system architecture with configurable system-on-chip (CSOC) technology, and an electrical output for controlling a door lock or the like. The use of CSOC architecture in lieu of conventional personal computer technology (e.g. mother boards, hard drives, video controllers and the like) allows for a more compact and cost efficient design. A plurality of remote access devices is configured for communication with a primary computer database wherein data corresponding to biometric samples for all authorized users is stored. In an embodiment wherein the biometric input devices comprise fingerprint scanners, the devices are configured to facilitate fingerprint identification by incorporating an auto-targeting capability that enables the user to simply place his or her finger on the fingerprint scanner whereafter the system adjusts the scanned image by automatically shifting the scanned image data to a properly targeted position thereby enabling the system compare the scanned print to the biometric samples in the system's data storage memory. Auto-targeting capability eliminates the requirement for manual targeting present in systems of the background art thereby improving system performance and minimizing reliance on human interaction. The present invention contemplates the use of auto-targeting with other biometric systems, such as facial recognition and/or retinal scanning systems, or any other biometric identification technology.

A significant data rate reduction effect in video coding is acchieved by quantizing the transformed frequency coefficients or components of a pixel block so that thereafter fewer amplitude levels need to be encoded and part of the quantised amplitude values becomes zero and need not be encoded as quantised amplitude values. Many transform based video coding standards use a default quantization matrix to achieve better subjective video coding/de-coding quality. A quantization matrix assigns smaller scaling values to some frequency components of the block if the related horizontal and/or vertical frequencies are believed to be the less important frequency components with respect to the resulting subjective picture quality. The inventive quantization matrix generation starts from default quantization matrices and derives therefrom a perceptually optimum quantization matrix for a given picture sequence. In a first pass the candidate quantization matrix for a given picture sequence is iteratively constructed by simultaneously increasing scaling values for some coefficient positions and decreasing scaling values for other ones of the coefficient positions. In a second pass the generated quantization matrix is applied for re-encoding the picture sequence.
