Capacity-independent demand assessment
Systems and methods are described to enable assessment of demand for points of presence (POPs) within a content delivery system, independent of the capacity of such POPs. The content delivery system can utilize load balancing technology to distribute user requests for content to various POPs, based at least partly on the capacity of the POPs. Because load balancing generally occurs prior to a user's connection to a POP, the monitored load of individual POPs may not accurately reflect user demand for the individual POPs services. Accordingly, systems and methods are disclosed to correlate pre-load-balancing requests, such as DNS requests, with post-load-balancing demand levels. Thereafter, the determined correlation can be utilized to assess user demand for individual POPs, independent of the observed load on that individual POP.

Light source module
A light source module including a body in which a light emitting device is disposed may be provided. The body includes: a main body including a top surface, a bottom surface, a first side, and a second side; a first subsidiary body disposed on the first side of the main body; and a second subsidiary body disposed on the second side of the main body. The first subsidiary body includes a first extension part extending from the first side and a second extension part extending from the first extension part. Each of the first extension part and the second extension part has a top surface and a bottom surface. The bottom surface of the first extension part and the bottom surface of the second extension part are disposed on the same plane with the bottom surface of the main body. The top surface of the first extension part is disposed lower than the top surface of the second extension part and the top surface of the main body, and the top surface of the second extension part is disposed lower than the top surface of the main body. The second subsidiary body is symmetrical with the first subsidiary body with respect to the main body. The light source module according to the embodiment can be mechanically coupled to another light source module having the same body as that of the light source module. The light source module according to the embodiment can provide a light source which is obtained by connecting a plurality of the light source modules and thus has a user's desired length. The light source module according to the embodiment can be used a light source of various lighting products, for example, a fluorescent lamp, a flat panel lighting device, etc. |

Substrate for LED with total-internal reflection layer surrounding LED
A packaged LED module includes an LED die mounted on a substrate surface. Formed on the substrate surface and surrounding the die is a first layer of a low index of refraction material. A lens of a higher index of refraction material is molded over the LED die and the first layer. The interface of the lens and the first layer reflects light by total internal reflection (TIR), in accordance with Snell's Law, when the LED light impinges at greater than the critical angle. The first layer may be a low index epoxy, silicone, or other material. In another embodiment, a layer surrounding the LED die is processed after the lens is formed to create an air/lens interface for TIR. The LED die may include a phosphor layer, which results in even more side light being reflected off the interface and not absorbed by the substrate surface. |

Process for preparing a semiconductor structure for mounting
A process for preparing a semiconductor structure for mounting to a carrier is disclosed. The process involves causing a support material to substantially fill a void defined by surfaces formed in the semiconductor structure and causing the support material to solidify sufficiently to support the semiconductor structure when mounted to the carrier. |
