International Classification:

G01R 31/00
G01R 31/02

US Classification:

324754, 324770, 3241581

Abstract:

A system performs continuous full linear scan of a flat media. The system includes, in part, a chuck, and at least first, second and third gantries. The chuck is adapted to support the flat media during the test. The first gantry includes at least one linear array of non-contacting sensors that spans the width of the flat media and is adapted to move across an entire length of the flat media. Each of the second and third gantries includes a probe head that spans the width of the flat media and each is adapted to apply an electrical signal to the flat media. Each probe head is further adapted to move along a direction substantially perpendicular to the surface of the flat media during the times when the first gantry is in motion and while test signals are being continuously applied.

Appl. No.:

13/730502

Inventors:

Jeff Berwick - Sunnyvale CA, US
David J. Baldwin - Allen TX, US

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

H03F 3/45

US Classification:

330254

Abstract:

An apparatus and method are provided. Generally, an input signal is applied across a main path (through an input network) and across a cancellation path (through a cancellation circuit). The cancellation circuit subtracts a cancellation current from the main path as part of the control mechanism, where the magnitude of the cancellation current is based on a gain control signal (that has been linearized to follow a control voltage).

Abstract:

In an electro-optic light modulator requiring an electro-optical sensor material such as polymer dispersed liquid crystal, or PDLC is directly coated on an optical glass substrate with a transparent electrode, such as indium tin oxide (ITO) and an optional layer of passivation coating such as silicon dioxide (SiO) on its surface. A thin layer of polymeric adhesive is coated on top of PDLC layer and then this two-layer coating is laminated with a dielectric mirror on a polyester film (Mylar™) preferably with the assistance of a vacuum.

US Classification:

32475403, 356213, 374100, 374E01001

Abstract:

A probe system for facilitating the inspection of a device under test. System incorporates a storage rack; a probe bar gantry assembly; a probe assembly configured to electrically mate the device under test; and a robot system for picking the probe assembly from the storage rack and deliver the probe assembly to the probe bar gantry. The robot system is also enabled to pick a probe assembly from the probe bar gantry and deliver the probe assembly to the storage rack. The probe assembly includes a clamping assembly for attaching the probe assembly to the probe bar gantry or the storage rack. The probe assembly may include an array of contact pins configured to mate with conductive pads on the device under test when the probe assembly is installed on the probe bar gantry assembly.
