A client device presents streaming media and includes a stream manager, a request accelerator, and a source component coupled to the stream manager and the request accelerator for determining which requests to make. A rate selection process can make rate decisions so that the buffer is filled when it is low, avoiding erratically changing rates and can choose the correct steady rate quickly. Multimedia download strategies can be used for HTTP that allow for accurate rate estimations, achieving link capacity even if network delays and packet loss rates are high, achieving timely delivery of the stream, and achieving relatively steady download rates with little short term variability. A receiver might use multiple HTTP connections, decompose media requests into smaller chunk requests, synchronize the connections using TCP flow control mechanisms, and request data in bursts. In addition, the receiver might use an HTTP pipelining process to keep the connections busy.

A microbolometer IR FPA is provided with in-situ vacuum sensing capability by realizing that the IR sensor microbolometer pixel element itself may be used as a vacuum sensor. The application of an electrical signal to the resistive element heats the bolometer material thereby producing a variable resistance related to vacuum level. The degree of variability for a given material depends on the efficiency of heat transfer from the material to the surrounding environment. In a good vacuum, heat transfer is poor, and thus heat will be retained in the material to produce a relatively large temperature increase and the resistance variability will be large. In a poor vacuum, heat is readily transferred to the environment and the temperature rise will be relatively small and thus resistance variability will be small. Consequently, the variable resistance magnitude can be readout to determine the vacuum level.

An improved profileometry data collection and analysis system employing software that performs clustering analysis on library data stored in memory that represent semiconductor chip wafer profiles, for use in matching real-time data signals from data collected by profileometry instruments. To better perform a match in real-time between the incoming real-time data signals and the profile library data, cluster analysis is performed on the library data to partition the library data into clusters, and to extract representative cluster data points of the clusters. The representatives of the clusters are stored in primary memory (e.g., RAM), while the data forming the clusters are stored in secondary memory (e.g., a hard drive). A real-time data signal is then first compared to the representative cluster data points, and when a match is made with a particular representative cluster data point, the cluster associated with the representative cluster data point is loaded from secondary memory into primary memory. Next a further search is made with the incoming real-time data signal to find the closest match to the data in the cluster. In this way the entire library data does not have to be searched sequentially, and the entire library does not have to reside in primary memory in order to be quickly searched, which both conserves time and primary memory.

A photoresist exposure process is disclosed which produces features which are substantially smaller than the aperture dimension of the mask used to make the feature. The smaller feature size results from a double exposure of the photoresist, combined with a double baking process to create the features in the photoresist. The double baking process thins the layer of photoresist, prior to the second exposure, thereby improving the resolution of the mark created by the second exposure on the photoresist. The process also uses a binary bias mask through which the first exposure is made, which overlaps with the area of the second exposure, to allow a process tolerance for the realignment of the mask over the wafer for the second exposure.
