Abstract: In an electronic delivery system, digital media items (e.g., videos, music, video games, ebooks, etc.) are stored in an ordered list (e.g., queue) at a provider system. The provider system automatically delivers digital media items to a user system (e.g., via a network connection). The user is permitted to check out (e.g., view, play, read, etc.) a maximum allowed number of items at the user system. If the user checks in an item, or an item expires or is removed from the queue, then the user is permitted to check out (or renew) digital media items in the queue until the maximum allowed number of digital media items are checked out. In some implementations, digital media items are automatically delivered in response to one or more trigger events (e.g., an item is removed from the queue, etc.).

Abstract: A computing device generates an audio signal that includes a pattern and transmits the audio signal to the loudspeakers. A measuring device located at a listening position sequentially captures the signal and pattern reproduced by the speakers. The measuring device transmits each captured signal and pattern to the computing device. The computing device determines the frequency and impulse responses for each loudspeaker and equalizes the speakers for the listening position. Some or all of the speakers may be associated with additional listening positions. The computing device may then equalize the speakers based on each listening position. Alternatively, the computing device may calculate an average for some or all of the listening positions and equalize the speakers based on the average.

Abstract: A clock frequency multiplication circuit. A circuit is described for receiving a clock signal of a first frequency X and multiplying the frequency of the signal by a multiple N to produce a signal of frequency N times X. The circuit is particularly useful in, for example, computer systems in which it is desired to upgrade certain components such as a processor to operate at an increased clock speed without modifying the clock speed of the system clock and where it is further desired to provide synchronization between the system clock and the processor clock.

Abstract: An apparatus and method for processing of interrupts in a computer system includes interrupts which are presented substantially simultaneously to each of a plurality of processors in the computer system. Each of the plurality of processors may respond to the interrupts and the first processor assigned to handle the interrupt prevents the other processors from handling the interrupts. The present invention further discloses means for disabling processors from responding to interrupts.
