Patent number: 5877008Abstract: An electromechanical device for driving the tip of a microinjection cannula, or needle, through the outer barrier of a blastocyst, cell, or cell nucleus for the injection of cells or other bioactive materials. Either a flexible frame or a ram moving within a base member is employed. Cannula motion is achieved by means of a piezoelectric stack and spring return system. The thrust motion over a predetermined microscopic distance is achieved without cannula setback prior to the thrust movement. Instead of specially prepared beveled and tipped needles, standard unimproved cannulas or needles can be used.Type: GrantFiled: July 22, 1997Date of Patent: March 2, 1999Assignee: Lockheed Martin Energy Research CorporationInventors: Carl J.

Patent number: 5825501Abstract: A structure and yarn sensor for fabric directly determines pick density in a fabric thereby allowing fabric length and velocity to be calculated from a count of the picks made by the sensor over known time intervals. The structure and yarn sensor is also capable of detecting full length woven defects and fabric. As a result, an inexpensive on-line pick (or course) density measurement can be performed which allows a loom or knitting machine to be adjusted by either manual or automatic means to maintain closer fiber density tolerances. Such a sensor apparatus dramatically reduces fabric production costs and significantly improves fabric consistency and quality for woven or knitted fabric.Type: GrantFiled: March 14, 1997Date of Patent: October 20, 1998Assignee: Lockheed Martin Energy Systems, Inc.Inventors: David K. Mee, Glenn O. Allgood, Larry R. Mooney, Michael G. Duncan, John C. Turner, Dale A. Treece
