Abstract: A log-periodic dipole array system employs a structure for the transmitter and the receiver designed in a way such that they compensate for the non-linear characteristics of each other to realize linear phase characteristics as a pair. Radiation elements on the receiver are positioned with respect to its corresponding transmission line in an order opposite to the positioning of the radiation elements on the transmitter. Although neither the transmitter dipole array nor the receiver dipole array itself has linear phase characteristics, the overall dipole array antenna system can realize linear phase characteristic.

Abstract: When a resistance load inverter is used to control lighting/non-lighting of a pixel, in accordance with characteristic variations of a transistor forming the resistance load inverter, variations occur in light emission of each pixel. As an inverter in a pixel, an N channel transistor and a P channel transistor are used to apply a CMOS inverter. Even when characteristics of the transistor forming the CMOS inverter vary and inverter transfer characteristics vary, there is little effect on controlling lighting/non-lighting of the pixel, therefore, light emission variations of each pixel can be eliminated. Further, a signal potential of a scan line is used as one power source of a potential of the inverter, therefore, an aperture ratio of the pixel can be increased.

Abstract: Embodiments of the invention provide methods and systems to deform a computer-generated three-dimensional surface using a lattice of rigid bone segments driven by an interpolation algorithm to define a muscle. Such embodiments allow a realistic presentation of subdermal muscle mass. In one embodiment, each end of a curve, created by an interpolation function, is attached to a corresponding bone. One or more muscle segments are attached along the curve. The curve along with the attached muscle segments defines a muscle. As the bones move and rotate the curve is expanded or contracted due to the endpoints of the curve being fixed to distinct bones. The attached muscle segments will experience corresponding expansion and contraction thus providing a realistic presentation of skin deformation. For one embodiment, the position of each muscle segment is determined in reference to a standard Bezier interpolation function.

Abstract: When a plurality of coplanar shapes are rendered over one another by performing a hidden surface removal operation using the Z value, a reference plane is specified, and the Z value of each point of a shape to be rendered on the reference plane is uniquely calculated based on the Z value of the rendering start point, the Z value gradient dZdx for the X direction, and the Z value gradient dZdy for the Y direction. Thus, any coplanar shapes will have the same Z value for each point shared therebetween. Therefore, if the rendering process is performed under such a rule that a shape is overwritten when the Z value of the new shape is less than or equal to the current Z value, it is ensured that the previously-rendered shape is always overwritten with a later-rendered, coplanar shape. Thus, it is possible to prevent a phenomenon that some pixels of a later-rendered shape that are supposed to be displayed are not displayed.
