Filed:

Apr 25, 2008

Appl. No.:

12/109662

Inventors:

William David Irwin - Elizabethtown PA, US
Keith Edwin Miller - Manheim PA, US

Assignee:

Tyco Electronics Corporation - Berwyn PA

International Classification:

H01R 29/00

US Classification:

439489, 439510

Abstract:

A mechanical device that indicates prior mating. The device comprises a first part having a first conductive device movable from a first position to a second position and a plurality of second conductive devices, and a second mating part including a plurality of third conductive devices mateable to the plurality of second conductive devices. On initial mating of the first and second part, the second part causes the movable first conductive device to move from the first position to a second position where it is captured, while closing a circuit that causes a signal to be sent. Further mating of the first and second parts connects the plurality of second conductive devices to the plurality of third conductive devices. In subsequent unmating and remating of the first and second parts, the first conductive device, being captured in its second position, does not result in a circuit closing before the plurality of second conductive devices mate with the third conductive devices. Either no signal is generated or the signal is ignored since the timing of the closing of the circuit is not prior to the mating of the plurality of second conductive devices with the third conductive devices.

International Classification:

H01H 19/20

US Classification:

200570

Abstract:

An electrical contact member for use with a rotary interface within a connector assembly is provided. The electrical contact member includes a lower portion adapted to receive an electrical wire; and a laterally deflectable upper portion connected to or formed integrally with the lower portion. The upper portion further includes a first lateral extension arm having a first contact point formed at the tip thereof and a second lateral extension arm having a second contact point formed at the tip thereof.

Appl. No.:

12/135255

Inventors:

William D. IRWIN - Elizabethtown PA, US

Assignee:

TYCO ELECTRONICS CORPORATION - Berwyn PA

International Classification:

H01R 13/02
H01R 43/04

US Classification:

439884, 29881

Abstract:

Provided is a contact pin with a solder cup. The solder cup is formed directly from the contact pin by a manufacturing process. The manufacturing process includes the steps of providing a wire, securing the wire in a carrier structure, cutting the wire to a predetermined length to form a contact, coining a first end of the contact to a predetermined thickness and forming the first end of the contact into a solder cup.

International Classification:

H01P 800

US Classification:

318696

Abstract:

A method for generating stepper motor ramps and analyzing the motor torque required compared with the motor torque available wherein the generated ramp accelerates the motor as fast as possible while maintaining a user settable torque safety factor and/or safety margin. The method uses the minimum available stepper motor torque at the current motor speed to ultimately compute the maximum useable acceleration, uses the maximum acceleration to generate the next motor step time and hence the next motor velocity, computes the next velocity from the desired acceleration and the previous velocity and utilizes friction during deceleration of the motor. In particular, the method comprises determining the minimum available torque using the current motor velocity and the torque-speed characteristic of the motor, applying to the available torque a safety factor and then a safety margin to determine maximum useable torque wherein the safety factor is derived from motor information and the safety margin is derived from system information, calculating the maximum acceleration using the friction and moment of inertia of the system and the maximum usable motor torque, calculating the time duration of the next step for advancing the motor, repeating the foregoing steps to determine all steps in the ramps, and utilizing the generated motor ramps in advancing the stepper motor. The generated ramp always exploits the full drive capability of the stepper motor, and it provides a relatively constant margin between available torque and required torque during both acceleration and deceleration of the motor.

Abstract:

A method of operating a photographic printer to provide for automatic setup for a plurality of film types and conditions in which film term data for film types encountered by the printer is automatically created and periodically updated to reflect current experience using accumulated historical density data derived from scanning of film strips and in which exposure of image frames from a current film strip to a photosensitive medium is adjusted either by average density information stored for one or more film types from the historical data or by average density information derived from the current film strip with determination of which average density information to use being made automatically by comparison of either or both of film type or average minimum density information of the film strip with the corresponding stored information. Automatic adjustment of tungsten illumination exposure and automatic updating of slope compensation factors for under- and over-exposed negatives are also described.
