A method and system for removing head motion from facial motion capture data. The method includes receiving a set of measured points of a target model, wherein each point is associated with coordinates in a 3D space. The method includes computing an optimal affine transformation function. The computing includes selecting an unprocessed point from the set of measured points. The computing includes selecting two nearby neighboring points of the unprocessed point. The computing includes computing an affine transformation function that minimizes an L2-norm error. The computing includes identifying the optimal affine transformation function from a set of computed affine transformation functions. The method includes displaying an aligned target model and reference model utilizing the optimal affine transformation function. The method includes outputting the optimal affine function to a computer-readable storage medium.

A wall and roof venting system comprising a wall having an outer layer disposed outwardly of an inner layer with a plurality of spacers disposed therebetween to provide a wall air flow channel between the wall layers. Exterior air enters at the bottom of the wall and vented air is discharged near the top of the wall to reduce heat transfer into the building. Preferably, vented air flows into a roof air flow channel disposed between a first roof layer and a second roof layer maintained in spaced apart relation by a plurality of roof spacers therebetween. A vent component is disposed in a gap in the upper roof layer at or near the top end of the roof to beneficially disperse and/or utilize the vented air from the air flow channels. The wall and roof spacers have openings therein to permit vented air to flow through the respective channels.

An electrical alternating current power signal and a circuit and method for generating the same in which the alternating current signal is dropped once at a non-zero crossing point in every 540 plus N degrees, where N is a non-negative number. This manner of controlling power to a device enables wide ranges of power control while generating acceptable levels of power line harmonics and while conforming to existing international regulations governing voltage variations.

Systems and methods for prerating communication events, such as telephone calls, for prepaying customers are described. The systems and methods permit, at the beginning of a communication event, the determination of a time limit for the event based on the available balance in a prepayment account associated with the event.
摘要:
A toner for printing documents that are difficult to forge and that are readily easy to visually verify and methods of using and forming the toner are disclosed. The toner includes a colorant for printing an image on a surface of a document and a dye for forming a latent version of the image underneath a surface of a substrate. An image formed using the toner of the invention is readily verified by comparing the colorant-formed image and the dye-formed image.

Disclosed is a simulation based environment that allows a product based engineer, with a modest understanding of complex software programs, to use complex math models. The system provides an interface by which basic component models can be used within the simulation. Allowances are made for particular variables to be adaptable by the product based engineer.

A knee bolster for a vehicle has an air bag and an air bag inflator. The air bag has an inflated condition and a deflated condition. The air bag is attached to the knee bolster, which is moveable with the air bag. The knee bolster may move from an unactuated position when the air bag is in the deflated condition to an actuated position when the air bag is inflated. A guide structure, which is attached to the knee bolster directs the bolster along a linear path from the unactuated position to the actuated position.
摘要:
A roof system for sloped metal roofs utilizing plywood decking, corrugated metal panels and one or more spacers disposed between the decking and metal panels for holding the metal panels vertically above the decking. The spacers have a planar top section, a planar bottom section and a center section to hold the top and bottom sections in spaced apart relation. The spacers also have one or more openings to form an airflow cavity between the decking and metal panels to permit the circulation of air therein. In the preferred embodiment, a thermal barrier layer is disposed between the spacers and the decking and the airflow cavity connects to a ridge vent located at the ridge of the roof and an eave vent at the eave of the roof. The roof system allows ambient air to be drawn into the eave vent to circulate through the airflow cavity and out the ridge vent in order to prevent thermal flexing of the metal roof and the build-up of moisture between the metal panels and decking.
