Abstract: Approaches are described for security and access control for computing resources. Various embodiments utilize metadata, e.g., tags that can be applied to one or more computing resources (e.g., virtual machines, host computing devices, applications, databases, etc.) to control access to these and/or other computing resources. In various embodiments, the tags and access control policies described herein can be utilized in a multitenant shared resource environment.

Abstract: A portable apparatus for holding a plastic bag. The portable apparatus comprises a base member which includes at least two substantially parallel and substantially horizontally disposed support members. A pair of upstanding leg members is connected closely adjacent a first end thereof to the base member closely adjacent a back portion thereof. A brace member is disposed substantially horizontally and connected closely adjacent a second end of the pair of upstanding leg members. There is at least two substantially parallel and substantially horizontally disposed arm members connected at a first end thereof closely adjacent one of a second end of a respective one of such pair of upstanding leg members and closely adjacent each end of such brace member. Further, there is a means engageable with at least one of the at least two arm members and the second end of such pair of upstanding leg members for holding such plastic bag.

Abstract: A method and apparatus is provided which continuously filters scrubbed gases prior to emission to the atmosphere. In particular, the method and apparatus can continuously scrub the effluent stream from a chemical vapor deposition process, such as the process used to deposit epitaxial silicon. In order to provide this continuous scrubbing, a separation housing having a filter housing is provided that permits the filter to be replaced during and without interruption of the scrubbing and filtering process. The filter housing can define a pair of tracks that guide the insertion and removal of a filter such that inserting a clean filter into one end of the pair of tracks causes a spent filter to be pushed out of the opposed end of the tracks as the clean filter is slid down the tracks.

Abstract: A chair is provided that is specifically designed for use in a clean room environment by limiting the emission of particles by the chair as clean room personnel alternately sit down and stand up. The chair includes a base and a seat member operably mounted upon the base. The seat member, in turn, includes a cushion and a shell encapsulating the cushion. The shell is comprised of polytetrafluoroethylene (PTFE). By encapsulating the cushion, such as a foam rubber cushion, in a PTFE shell, the chair limits emission of particles by the cushion.
