US Patent:

20020063566, May 30, 2002

Filed:

Sep 28, 2001

Appl. No.:

09/966874

Inventors:

Christopher Bruno - Attleboro MA, US
Mark Estrella - Watertown MA, US
Mark O'Brien - East Boston MA, US

International Classification:

H01H031/04

US Classification:

324/538000

Abstract:

A mechanism for attaching a device interface board (DIB) to a surface of a test head or peripheral includes first and second pulldown mechanisms attached to the surface and a substantially U-shaped actuator. Each of the pulldown mechanisms includes a rotating member coupled to a connecting member via a translation interface. The translation interface converts rotation of the rotating member into vertical movement of the connecting member. The U-shaped actuator has first and second ends respectively coupled to the rotating members of the first and second pulldown mechanisms. Swinging the U-shaped actuator through an arc rotates the rotating members and causes the connecting members to move vertically. A DIB that latches with the connecting members can thus be pulled down against the surface quickly and conveniently, with sufficient mechanical leverage for compressing large numbers of spring-loaded pins.

Appl. No.:

11/211895

Inventors:

Mark O'Brien - Natick MA, US
John Sherry - Needham MA, US

International Classification:

A61F 2/06

US Classification:

623001350

Abstract:

An endoluminal device adapted to be deployed in a branched body lumen is provided by intraluminal delivery from an access location remote from the location at which the device is to be deployed, i.e. by introduction through one of the branches of the branched body lumen. The device comprises an unbranched portion, a first branch portion and second branch portion in communication with the unbranched portion, and a distortion element removeably connected to the first branch portion for manipulating the geometry of the second branch portion. The distortion element extends along the first branch portion and back to the access location.

International Classification:

G01M 7/02

Abstract:

An example test system includes a tray to hold devices, where the devices include devices to be tested or devices that have been tested; a motor that is controllable to cause vibrations; and a component that couples the motor to the tray to cause the tray to vibrate in response to the vibrations of the motor.
