Patent number: 6139496Abstract: An ultrasonic imaging system having an electronic control and signal processing circuit section interconnected with an improved probe assembly suitable for use in varied applications of ultrasonic imaging, especially in medicine, and in other fields of use. The probe assembly indudes an operator interface and a sensor head, both of which are structurally integrated within a compact housing according to a predetermined spatial relationship, such that an operator can position the probe assembly so as to locate the display adjacent the physical structure that is subject to isonification while simultaneously viewing, on the operator interface, an ultrasonic image of the physical structure. The ultrasonic image is thereby considered to be observable through an "acoustic window" that is implemented in the view provided in the operator interface.Type: GrantFiled: April 30, 1999Date of Patent: October 31, 2000Assignee: Agilent Technologies, Inc.Inventors: James N C Chen, Michael Atlas

Patent number: 4653794Abstract: A universal gripper particularly adapted for handling parts such as axial leaded electronic components. The gripper includes a pair of jaws with depending fingers mounted on a baseplate for linear motion equally about the centerline of the baseplate. A long stroke cylinder is mounted between the jaws and is adapted for opening and closing the gripping fingers through a relatively long stroke. A short stroke cylinder is affixed to one of the jaws and includes a yoke portion extending to the other jaw. Locking apparatus is provided for selectively locking the yoke portion to the other jaw. When the locking apparatus is activated, the short stroke cylinder opens and closes the fingers through a relatively short stroke. In this way, electronic components can be handled without crushing the leads. Because of the provision of the short stroke cylinder, the disclosed gripper can be used in tight areas. A center push cylinder is provided for ejecting parts from the gripping fingers.Type: GrantFiled: February 12, 1986Date of Patent: March 31, 1987Assignee: Northrop CorporationInventor: Michael Atlas
