Assignee:

Openwave Systems Inc. - Redwood City CA

International Classification:

G06F 15/173

US Classification:

Abstract:

A system and method provide for establishment and use of permission sets for subscribers where client applications in a wireless communication environment are requesting location information for a particular wireless communications device from a provider of such information. The system described herein provides the capability for a wireless communications device operator to establish a profile wherein limitations may be placed on the provision of such location information based on such things as the requesting party, spatial and temporal limitations, as well as granularity. The system described herein may be further configured such that an authentication process is preformed for client application seeking location information which would require the registration of such client applications with a centralized processing system.

Abstract:

Methods for making a tribological bearing wear surface for a compressor component are provided. Such methods involve semi-solid metal casting, where an admixture of solid lubricant particles and a metal alloy material is heated to melt the metal alloy material, while the lubricant particles remain in a solid phase. The alloy material and solid lubricant have substantially different densities. The metal alloy material may be a copper, iron, or aluminum alloy, for example. The method further comprises mixing and cooling the admixture to form a semi-solid slurry admixture. Next, the method comprises introducing the semi-solid slurry admixture into a die. Finally, the semi-solid slurry admixture in the die is solidified to form a solid component having the solid lubricant particles homogenously distributed within a metal alloy material matrix, thus forming a metal matrix composite. Compressor components made from such methods are also provided.
