Abstract: A method is provided for testing for presence of a particulate selected from the group consisting of: a microorganism, a fungus, a bacteria, a spore, a virus, a mite, a biological cell, a biological antigen, a protein, a protein antigen, and a carbohydrate antigen. The method includes (a) collecting, in a tube (22), fluid that potentially contains the particulate, (b) using a plunger (24) to push the fluid through a filter (26) disposed at a distal portion of the tube or at a distal end of the plunger, and subsequently, (c) while the filter is inside the tube, ascertaining if any of the particulate was trapped by the filter by applying a particulate-presence-testing-facilitation solution to the filter. Other embodiments are also described.

Abstract: A valve unit for an aircraft is provided. The valve unit includes valve assembly; and a servo controller coupled to the valve assembly and configured to control operation of the valve assembly. At least a portion of at least one of the valve assembly or servo controller is formed by a high temperature aluminum alloy.

Abstract: Embodiments of the present invention provide the ability to accurately match a particular computing device within a networked computing environment with an identity of that computing device. According to one aspect, a method for identifying a client computing device in a networked computing environment is provided. The method receives a discovery data record that includes a hardware identification and a logical identification, and in response, queries a plurality of client records for a matching client record. If a matching client record is identified by the query it is compared with the received discovery data record to identify the client computing device.

Abstract: Client collection membership evaluation techniques are described. In an implementation, attributed are identified that define membership in one or more collections. A plurality of clients is monitored for changes to computing resources that correspond to the identified attributes. Membership of clients having the changes is evaluated using one or more queries that include one or more of the identified attributes from respective collections.
