Appl. No.:

12/531849

Inventors:

Bin Li - Chantilly VA, US

Assignee:

BAE Systems Information and Electronic Systems Integration Inc. - Nashua NH
Ovonyx, Inc. - Rochester Hills MI

International Classification:

G11C 11/00

US Classification:

365163, 365148

Abstract:

A write circuit for providing distinctive write currents to a chalcogenide memory cell is disclosed. The write circuit includes a current amplitude trim module, a current amplification and distribution module, and a write current shaping module. The current amplitude trim module provides a well-compensated current across a predetermined range of temperatures, voltage supplies and process corners intended for programming a chalcogenide memory cell. The current amplification and distribution module amplifies the well-compensated current in order to meet a programming requirement of the chalcogenide memory cell. The write current shaping module supplies an appropriate amount of write “0” current or write “1” current, based on the amplified current, to program the chalcogenide memory cell accordingly.

US Classification:

365163, 36518916, 365210

Abstract:

An adjustable write pulse generator is disclosed. The adjustable write pulse generator includes a band-gap reference current, a programmable ring oscillator, a frequency divider and a single pulse generator. The band-gap reference current circuit generates a well-compensated current over a predetermined range of temperatures needed to program a chalcogenide memory cell. The programmable ring oscillator generates a first set of continuous write “0” and write “1” pulse signals based on the well-compensated current. The frequency divider then divides the first set of continuous write “0” and write “1” pulse signals into a second set of continuous write “0” and write “1” pulse signals. The single pulse generator subsequently converts the second set of continuous write “0” and write “1” pulse signals into a single write “0” pulse signal or a single write “1” pulse signal when programming the chalcogenide memory cell.

International Classification:

H01R 1718

US Classification:

439578

Abstract:

A coaxial connector (1) in which a conductive housing (2) is provided with a projecting electrical terminal (8), a conductive shell (3) and an insulative body (4) are encircled by the housing (2), a central electrical contact (5) for transmitting an electrical signal is concentrically encircled by the insulative body (4), and an electrical terminal portion (33) of the contact (5) projects from the shell (2), and an extended axial stem portion (21) of the insulative body (21) projects outwardly from the conductive housing (2) and encircles the terminal portion (33) to provide a lengthy voltage creepage path and a lengthy voltage clearance path.

Appl. No.:

6/665194

Inventors:

George W. Michael - Harrisburg PA

Assignee:

AMP Incorporated - Harrisburg PA

International Classification:

H02G 112

US Classification:

408 1R

Abstract:

A tool for trimming coaxial cable comprises a cable-holding member and a cutter-holding member. Sections of the cable-holding member and cutter-holding member are matable for movement relative to each other and they are initially secured together so that stop surfaces of these members are spaced from one another based on the amount of trimming that must be done to trim a cable to a precise electrical length. The end of the cable is secured in the cable-holding member with the end to be trimmed disposed against a cutter member secured to the cutter-holding member. The matable sections are unsecured, the cutter-holding member is rotated relative to the cable-holding member so that the cutter member trims the cable end until the stop surfaces engage.

International Classification:

H01R 905

US Classification:

439581

Abstract:

This invention is directed to a low profile coaxial cable connector assembly for edge mounting to a planar electronic device, such as a printed circuit board, where electrical circuitry is provided thereon for electrically interconnecting to the assembly. The assembly comprises a dielectric housing having at one end thereof a pair of spaced-apart, parallel walls adapted to straddle and be secured to the planar electronic device, and at the opposite end thereof a cavity for the reception of an electrically terminated coaxial cable. Within the other end a grounding contact clip is provided having a pair of parallelly extending spring metal arms for receiving the terminated coaxial cable, and a signal contact for mating with the terminated coaxial cable. The grounding clip and signal contact further include extensions therefrom for electrically interconnecting to said planar electronic device, where the extensions are exposed between the spaced-apart walls and may be soldered to complementary traces or pads on the surfaces of the planar electronic device.

US Classification:

439885

Abstract:

A method and apparatus for attaching electrical contacts (23, 24) to the ends of electrical conductors (50). The method of the invention comprises the steps of providing a plurality of contacts (23, 24) at spaced locations along a flexible strip (22), feeding the strip (22) to an attachment station (14) for delivering contacts (23, 24) to the attachment station (14), attaching a contact (23, 24) to the end of an electrical conductor (50) in the attachment station (14), and separating the attached contact (23, 24) from the stip (22). The contacts (23, 24) are incorporated into contact assemblies (20, 20') which comprise a contact (23, 24) having dielectric insulating member (25) molded therearound and molded integral with the flexible strip (22). After attachment of a contact (23, 24) to a conductor, the attached contact assembly (20, 20') is cut from the strip (22) and the strip (22) is indexed to deliver the next contact assembly (20, 20') to the attachment station (14).
