A system and method for real-time multi-view (i.e. not just frontal view) face detection. The system and method uses a sequence of detectors of increasing complexity and face / non-face discriminating thresholds to quickly discard non-faces at the earliest stage possible, thus saving much computation compared to prior art systems. The detector-pyramid architecture for multi-view face detection uses a coarse-to-fine and simple-to-complex scheme. This architecture solves the problem of lengthy processing that precludes real-time face detection effectively and efficiently by discarding most of non-face sub-windows using the simplest possible features at the earliest possible stage. This leads to the first real-time multi-view face detection system which has the accuracy almost as good as the state-of-the-art system yet 270 times faster, allowing real-time performance.

An electrical connector includes a wafer formed with a ground shield made from a non-conductive material made conductive with conductive particles disposed therein, thereby eliminating the necessity of the metal ground shield plate found in prior art connectors while maintaining sufficient performance characteristics and minimizing electrical noise generated in the wafer. The wafer housing is formed with a first, insulative housing at least partially surrounding a pair of signal strips and a second, conductive housing at least partially surrounding the first, insulative housing and the signal strips. The housings provide the wafer with sufficient structural integrity, obviating the need for additional support structures or components for a wafer. Ground strips may be employed in the wafer and may be formed in the same plane as the signal strips. The second, conductive housing may be connected (e.g., molded) to the ground strips and spaced appropriately from the signal strips. The wafer may also include air gaps between the signal strips of one wafer and the conductive housing of an adjacent wafer further reducing electrical noise or other losses (e.g., cross-talk) without sacrificing significant signal strength.

The invention discloses a safe state recognition system for people on the basis of machine vision, aiming to solve the problem that the corresponding intelligent control decision for the vehicle driving behaviour can not be formulated according to the safe state of the people in the prior art. The method comprises the following steps: collecting a vehicle-mounted dynamic video image; detecting and recognizing a pedestrian in an interested area in front of a vehicle; tracking a moving pedestrian; detecting and calculating the distance of pedestrian in front of the vehicle; and obtaining vehicle real-time speed; and recognizing the safe state of the pedestrian. The process of recognizing the safe state of the pedestrian comprises the following steps: building a critical conflict area; judging the safe state when the pedestrian is out of the conflict area in the relative moving process; and judging the safe state when the pedestrian is in the conflict area in the relative moving process. Whether the pedestrian enters a dangerous area can be predicted by the relative speed and the relative position of a motor vehicle and the pedestrian, which are obtained by a vision sensor in the above steps. The safe state recognition system can assist drivers in adopting measures to avoid colliding pedestrians.

Apparatus and Method for Optimizing the Efficiency of a Bypass Diode in Solar Cells. In a preferred embodiment, a layer of TiAu is placed in an etch in a solar cell with a contact at a doped layer of GaAs. Electric current is conducted through a diode and away from the main cell by passing through the contact point at the GaAs and traversing a lateral conduction layer. These means of activating, or "turning on" the diode, and passing the current through the circuit results in greater efficiencies than in prior art devices. The diode is created during the manufacture of the other layers of the cell and does not require additional manufacturing.

The present invention relates generally to automatic insurance verification, and more specifically, to a non-invasive method and system for automatically determining, by any person with computer, wireless, or telephone access and in real-time, if an insured object of value is or is not insured irrespective of insurer location, jurisdiction, language, type, time, and also the internal operations, software platform and communications protocols used by insurers and / or governmental entities. It is an insurance verification, not an insurance reporting or tracking system and because it maintains no personal data of any kind, and can modify no record, it can deliver only very limited features regarding reporting or tracking. The present invention can however, provide absolute assurance of current insurance status at all times, provides a unique method of access which resolves all current failures and is non-invasive, providing complete privacy for all parties involved, (the absence of all personal information and the access method used ensures that all access and data is inherently non-invasive). This invention further ensures that any check of status, at insurer or governmental registration, (including “e-registration”, inspection, or any other location and time when and where a jurisdiction or insurer requires such a status check, will result in an instant and totally accurate status response. This system is based upon the assignment of a unique identifier, also known in this present art as a “UC” or “Unique Code” which then provides a method of accurate data, (including status checks), without reliance on “VINs”, (vehicle identification numbers), policy number or other identifiers which are often incorrect. The UC is assigned to any combination of two or more elements that are “gleaned”, (file field extraction and related system and methods), one of which is always current status. The extraction of these selected fields from data streams may be done by a number of prior art techniques, and the three most common have been detailed. First demonstrated to government officials in 1999 as a medical version and later the same year as a vehicle version, it has been demonstrated and documented since to a great many Federal and State governmental entities. This present invention has also been demonstrated to several foreign governments but incorporates no technologies that create any possible security risk for any government, insurer, individual, and especially to the national security of the United States.

A filter capacitor comprising a substrate of at least one layer of a low temperature co-fires ceramic (LTCC) tape supporting alternating active and ground electrode layers segregated by a dielectric layer is described. The substrate is preferably a laminate of three LTCC tapes pieces that are heated under pressure and at a relatively low temperature to become a laminate that maintains its shape and structure dimensions even after undergoing numerous sintering steps. Consequently, relatively thin active and ground electrode layers along with the intermediate dielectric layer can be laid down or deposited on the LTCC substrate by a screen-printing technique. A second laminate of LTCC tapes is positioned on top of the active / dielectric / ground layers to finish the capacitor. Consequently, a significant amount of space is saved in comparison to a comparably rated capacitor or, a capacitor of a higher rating can be provided in the same size as a conventional prior art capacitor.
