Filed:

Feb 28, 2013

Appl. No.:

13/781607

Inventors:

David H. ARMSTRONG - Lafayette CO, US
Karl PEDERSEN - San Jose CA, US

Assignee:

ADVANTEST CORPORATION - Tokyo

International Classification:

G01R 1/36
H01H 71/74

US Classification:

32475407

Abstract:

An apparatus and method for protecting probes used in automated testing is disclosed. The apparatus comprises a probe operable to provide power to a device under test (DUT) from a device power source (DPS), wherein the probe is coupled to a contact point on the DUT and a probe protector circuit connected to the probe in series between the DPS and the DUT. The probe protector circuit further comprises a current sense module operable to monitor a flow of current from the DPS to the DUT to determine if the current flow is below a predetermined threshold current level and a switch for controlling the connection from the DPS to the DUT. The switch is coupled to the current sense module and is operable to be used in conjunction with the current sense module to limit the current flow if it exceeds the predetermined threshold current level.

Appl. No.:

8/979529

Inventors:

William R. Lawrence - Ft. Collins CO
David H. Armstrong - Boulder CO

Assignee:

Agilent Technologies, Inc. - Palo Alto CA

International Classification:

G01R 3128

US Classification:

714724

Abstract:

An apparatus and method are provided for testing component tolerances of a device for testing integrated circuits. The testing device is generally characterized by a plurality of test connectors disposed at a test head, wherein each test connector carries electrical signals for a test channel. Further, each test channel generally corresponds to a circuit board that includes at least one driver and one receiver. In this general type of tester, a system is provided that includes a specialized DUT board that establishes a low impedance electrical connection (i. e. , short) between electrical conductors of a first and second test connector. Through this low impedance path, a first driver from a first circuit board is directly connected (i. e. , shorted) to a first receiver on a second circuit board. A controller is configured to control the first driver to output an electrical signal at a predetermined time.

SLA PHARMA AG - LIESTAL

International Classification:

A61K 31/4164
A61K 9/00
A61K 47/06
A61K 45/06

US Classification:

424642, 514398, 514171, 5142392, 51425308, 514193, 514 29, 514 24, 514154, 424744, 514161, 5142222, 424653

Abstract:

A topical composition comprises at least 5 wt % metronidazole or a pharmacologically acceptable derivative thereof in a non-aqueous vehicle. The composition may be used in the treatment of conditions of the colon, rectum, anorectum and perianal region, in particular inflammatory bowel disease and perianal Crohn's disease. The composition also relieves pain and inflammation and promotes healing of the colon, rectum, anorectum and perianal region following surgical operations. One advantage of the composition is that topical administration of metronidazole results in a primarily local effect and thus side effects observed from systemic administration are avoided.
