Abstract: In general, in one aspect, the disclosure describes a method that includes interrupting a program running on a processor. The active instruction that was interrupted is identified. Event counts since a previous interrupt are harvested.

Abstract: A closure assembly includes a track and a slidable and pivotable closure member. The closure member is engaged with the track proximate first and second pivots adjacent the pivotable end of the member, the first and second pivots being interconnected by a multiple segment shaft (for example at least two portions) (for example telescoping) which provides for accurate installation, retention, removal, adjustment and alignment of the first and second pivots in a substantially parallel line for pivotally supporting the closure member so that it may be safely and securely pivoted away from the closure assembly.

Abstract: A pivoting and sliding closure assembly is provided which rides in a guide channel of a frame upon a pivot shoe assembly which at one end securely pivots a closure member upon one pivot shoe when the closure is pivoted away from the channel, and which latches the closure member in a slidable position when the closure member is pivoted to its latched position. The pivot shoes are connected together by a multiple segment shaft in the assembly and unique rack and pinion structure is incorporated in the assembly.

Abstract: A real-time media driver for scheduling and mixing media in a multimedia environment. Implemented to operate in conjunction with a non-real-time operating system, the real-time media driver comprises a wave driver which controls a predominant percentage of the operations of the media hardware device and a mini-device driver which is software provided by the vendor of the media hardware device to support functions unique to the particular media hardware device. Furthermore, the real-time media driver comprises a media scheduler which (i) synchronizes multiple media streams prior to being input into a mixing/splitting device of the media scheduler; (ii) allows reconfiguration of attributes of media streams without loss of content prior to and after operations by the mixing/splitting device; and (iii) appropriately mixes media to produce multi-channel media according to a certain "prioritized sharing" policies.
