Inventor: BALDWIN KEITH R
IPC: H03D3/00
Filed: 2001-12-11
Granted: 2003-04-21
Abstract: A method of controlling operation of a wireless device configured in a zero intermediate frequency architecture including a DC loop and a gain loop. The method includes processing energy in a wireless medium to generate a corresponding receive signal, monitoring the receive signal via a predetermined measurement window, detecting a changed condition in the channel, holding the gain feedback control loop at a constant gain level, and operating the DC loop in an attempt to search a stable DC value for the receive signal while the gain loop is held constant. A first case is DC saturation, where the gain is held constant until DC is controlled. A second case is clear channel assessment, where a prior stored gain setting is applied to the gain loop after detecting the end of the packet. A third case is preparation for receiving an expected acknowledgement packet after transmitting a packet, where again a prior stored gain setting is applied to the gain loop and DC is searched.

Subsequently, the carrier is turned upside down and the solder bumps thereon are aimed at openings having flux on the buildup substrate, and a reflow step is performed on the solder bumps. The Au layer is dissolved by tin (Sn) rapidly, namely, when tin contacts with the carrier, the solder bumps fall from the carrier, so that solder balls are formed on the buildup substrate. Because of the solder bumps are formed by plating, so that the uniformity of the solder bumps is high and the yield is improved. Therefore, the present invention can be applied for the manufacture of pre-solder bumps with fine pitch.

Granted: 2005-10-21
Abstract: A system and method are described for pushing child vertices to predetermined parent vertices to remove detail from an array of polygons. In one embodiment, a graphics engine identifies an LOD boundary that divides the array of polygons into low LOD and high LOD areas. The graphics engine identifies each child vertex that resides on the low LOD side of the LOD boundary as well as the parent vertices of that child vertex. Using a point pushing technique rule, the graphics engine determines which, if any, of the identified child vertices migrates to a parent vertex. The graphics engine identifies a predetermined parent vertex to which the graphics engine moves each migrating child vertex. The graphics engine pushes each migrating child vertex to its respective predetermined parent vertex. The graphics engine reverses this process to add detail to an array of polygons.
