An apparatus and method is characterized by providing an optical transfer function between a predetermined illuminated surface pattern, such as a street light pattern, and a predetermined energy distribution pattern of a light source, such as that from an LED. A lens is formed having a shape defined by the optical transfer function. The optical transfer function is derived by generating an energy distribution pattern using the predetermined energy distribution pattern of the light source. Then the projection of the energy distribution pattern onto the illuminated surface is generated. The projection is then compared to the predetermined illuminated surface pattern to determine if it acceptably matches. The process continues reiteratively until an acceptable match is achieved. Alternatively, the lens shape is numerically or analytically determined by a functional relationship between the shape and the predetermined illuminated surface pattern and predetermined energy distribution pattern of a light source as inputs.

Electronically programmed signs consist of any array of picture elements (pixels) that can be controlled independently to create an image. Varying the intensity of each pixel and adding multiple colors per pixel will enhance the image quality. It is currently common to have displays that use one, two or three separate colors in a pixel (monochrome, red-green, and red, green and blue) with intensity levels of two, four, eight up to 256 and beyond. Multiple colored pixels can combine colors at various intensity levels to expand the displayable color palette. The number of colors it is possible to display is calculated by the following formula:total⁢⁢number⁢⁢of⁢⁢displayable⁢⁢colors=(number⁢⁢of⁢⁢primary⁢⁢colors)(number⁢⁢of⁢⁢intensitylevels⁢⁢per⁢⁢colors)While raising the number of intensity levels and colors improves image quality, it also raises the viewer's sensitivity to inconsistencies in both parameters.

Implants, and processes for installing them, which replace the medial condyle and portions of the patellofemoral channel but preferably not portions of the lateral condyle that articulate relative to the tibia. Processes are provided which allow proper location and orientation of an anterior resection and a distal resection on the femur, which make use of a transition point which can be designated on the bone, for navigating proper positioning of such implants. Proper positioning of the implant relative to the femur for insuring a smooth transition between lateral portions of the implant and the lateral condyle is thus reduced to determining proper medial / lateral location of the implant on the anterior and distal resections. Such implants and processes can allow, among other things, for controlled location and orientation of an implant on the bone which saves lateral compartment bone, which eliminates the need to sacrifice the anterior and posterior cruciate ligaments, and which is adapted for minimally invasive surgery with its attendant benefits.

The hybrid curve comprises a plurality of self-similar curve sections, and, as the flare widens, each successive curve section is scaled up by a scaling factor and joined at its wider end with a neighboring curve section. The hybrid flared notch can also be implemented in antipodal and balanced antipodal Vivaldi aerials.

The invention discloses a live broadcast time shift method which is applied to a live broadcast network including a client and a server. The live broadcast time shift of a user on the client is divided into pause and play. The client acquires the time label of a first index file currently parsed by the client according to pause, and acquires the played time of a video clip corresponding to the first index file. The client determines the timestamp of pause in a live broadcast video according to the time label and the played time. When the client receives play, a live broadcast time shift request is sent to the server according to the time shift time and timestamp of play. The live broadcast video in the live broadcast network is parsed and played according to a second index file returned by the server. After a user who watches live broadcast carries out live broadcast time shift, discontinuous screen caused by play screen hysteresis and play delay is reduced, and the user experience is improved. The invention further discloses the client.
