US Patent:

7053640, May 30, 2006

Filed:

Dec 27, 2002

Appl. No.:

10/331714

Inventors:

David A. Feld - Newark CA, US
Daniel S. Lam - Santa Rosa CA, US
Paul D. Bradley - Mountain View CA, US

Assignee:

Agilent Technologies, Inc. - Palo Alto CA

International Classification:

G01R 31/02
G01R 31/28

US Classification:

324755, 324765

Abstract:

High port-to-port RF isolation for a test socket in a production RF test environment is achieved by establishing a coaxial-type connection between the test socket and the device under test (DUT). This coaxial-type connection results by at least partially surrounding each port of the DUT with a ground seal connected to RF ground connection. In one embodiment, the ground seal is a metallic base plate of the test socket which surrounds the RF connection to the DUT.

International Classification:

G06F 19/00

US Classification:

705003000, 715507000

Abstract:

A method and apparatus are provided for creating a referral network for member physicians utilizing the Internet. The referral network provides its members an organized and efficient system for generating and storing patient referrals. To become a member of the referral network, a physician registers with the referral network web site. A member physician generates a patient referral document using referral network software on the referral network web site. The patient referral document is sent to another physician to refer a patient to the physician. If the recipient physician is not a member of the referral network, the patient referral document includes a promotion for the referral network to induce the physician receiving the referral document to become a member of the referral network.

Abstract:

A superconductor consisting of a sufficiently pure phase of the oxides of Bi, Sr, Ca, and Cu to exhibit a resistive zero near 110K resulting from the process of forming a mixture of Bi. sub. 2 O. sub. 3, SrCO. sub. 3, CaCO. sub. 3 and CuO into aparticulate compact wherein the atom ratios are Bi. sub. 2, Sr. sub. 1. 2-2. 2, Ca. sub. 1. 8-2. 4, Cu. sub. 3. Thereafter, heating the particulate compact rapidly in the presence of oxygen to an elevated temperature near the melting point of the oxides to form a sintered compact, and then maintaining the sintered compact at the elevated temperature for a prolonged period of time. The sintered compact is cooled and reground. Thereafter, the reground particulate material is compacted and heated in the presence of oxygen to an elevated temperature near the melting point of the oxide and maintained at the elevated temperature for a time sufficient to provide a sufficiently pure phase to exhibit a resistive zero near 110K.
