摘要:
The present disclosure describes methods of heat treating Ti-based alloys and various improvements that can be realized using such heat treatments. In one exemplary implementation, the invention provides a method of forming a metal member that involves forming an alloy into a utile shape and cooling the alloy from a first temperature above a beta transus temperature of the alloy to a second temperature below the beta transus temperature at a cooling rate of no more than about 30° F./minute. If so desired, the alloy my be treated for a period of about 1-12 hours at about 700-1100° F. Titanium alloys treated according to aspects of the invention may have higher tensile strengths and higher fracture toughness than conventional wrought, mill-annealed Ti 64 alloy.
摘要:
A system, method, and computer program for data communication, or “handshaking,” between wireless devices and a server on a wireless network. Upon a wireless device communicating with the server, the server obtains data from the wireless device indicative of wireless device attributes, and the server determines access of the wireless device, based upon the wireless device attributes, to applications either resident on that server or on other computer devices on the wireless network.

摘要:
An apparatus, method, and article of manufacture that provides an efficient way to invoice the users of a communication system (100) for the system resources consumed. Invoicing is based upon flexible criteria that can be adapted depending upon the charges a resource provider charges. For example, a user may incur a one-time charge for downloading a desired application program, or the user may be charged a download fee plus a recurring monthly fee for having continual access to the program and any updates to the program. A fee might also be charged for each time the application is used. These fees are recorded as debits and transferred to an invoicing location where an invoice reflecting the debits is constructed. For example, the debits may comprise fees for wireless service access, Internet service access, downloaded application programs, data, multimedia services, or other fees.
