Filed:

Jul 6, 1999

Appl. No.:

09/348751

Inventors:

David Cheng - Sunnyvale CA 94087

International Classification:

G01R 1073

US Classification:

324754, 324758

Abstract:

A multiple test probe system is disclosed. The multiple test probe system includes a support and a mount pivotally coupled to the support. The mount is capable of pivoting to a number of testing positions. A number of probe assemblies are coupled to the mount and associated with a corresponding number of testing positions. The probe assemblies include a number of electrical contacts coupled to a number of wires in a probe bus regardless of a testing position of the mount. The multiple test probe system further includes an actuator coupled to the mount to cause the mount to move between the testing positions.

Abstract:

A workpiece loading interface is included within a workpiece processing system which processes workpieces, typically wafers, in a vacuum. The workpiece loading interface includes two separate chambers. Each chamber may be separately pumped down. Thus, while a first cassette of wafers, from a first chamber is being accessed, a second cassette of wafers may be loaded in the second chamber and the second chamber pumped down. Each chamber is designed to minimize intrusion to a clean room. Thus a door to each chamber has a mechanism which, when opening the door, first moves the door slightly away from an opening in the chamber and then the door is moved down parallel to the chamber. After the door is opened, a cassette of wafers is lowered through the opening in a motion much like a drawbridge. The cassette may be pivoted within the chamber when the position from which wafers are accessed from the cassette differs from the position from which the cassette is lowered out of the chamber.

Peter J. Potrebic - Calistoga CA, US
David J. Cheng - Cupertino CA, US

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

H04N 7/173

US Classification:

725 88, 725 39, 725134, 725141, 386 45, 386 83

Abstract:

Memory is allocated to record a program being broadcast proportional to its remainder in a client device having a processor in communication with a receiver. The processor executes an application to allocate space in the memory to record the remainder of the broadcast of the program being received by the receiver that has a predetermined time length. The executing application obtains the predetermined time length from the broadcast received by the receiver and derives the remainder of the broadcast of the program from the present time and the predetermined time length obtained from the broadcast. The space can be logically erased prior to its allocation. A video recorder records the broadcast of the program being received by the receiver in the space in the memory. A video playback device plays back the recorded broadcast of the program from the space in the memory.
