Patent number: 11108149Abstract: A microwave antenna includes an antenna housing and a radome fabric attached to the housing, which is configured to pass microwave electromagnetic signals therethrough. The radome fabric has an opening formed therein. A vent component is attached to the radome fabric so as to cover the opening in the radome fabric when the radome fabric is viewed from an elevation view in a direction parallel to an axis extending through and perpendicular to the opening in the radome fabric. The vent component is configured to allow air to pass between the atmosphere and the antenna housing.Type: GrantFiled: June 28, 2017Date of Patent: August 31, 2021Assignee: COMMSCOPE TECHNOLOGIES LLCInventors: Steven M.

Publication number: 20160048807Abstract: A system and method for recruiting that utilizes a combination of pre-categorized and filtered candidate profiles coupled with a discerning search followed by contact with a live representative. A searcher selects candidate criteria as either required or optional. The searcher's selections are compared against a proprietary database of candidate profiles, and are sorted based on the criteria selections of the user. Criteria marked as required are weighted at 100%, while those that do not possess them are weighted at 0%. Criteria marked as optional are weighted at 100%, but if they do not match the candidate the optional criteria are weighted at 50% of the value based upon the number of criteria selected by the searcher. Based on the sorting, the searcher receives a report of qualified candidates ranked by a percentage matched based upon the selected criteria.Type: ApplicationFiled: August 13, 2015Publication date: February 18, 2016Inventors: Daniel A. Kreuter, Steven M. Clark

Patent number: 6866461Abstract: The present invention comprises a loading device for automating transfer of a plurality of probes between a cassette within which the plurality of probes are initially constrained and an analytical instrument, e.g., mass spectrometer. The loading device may be configured to accept a single or a plurality of cassettes each removably constraining a plurality of probes to be analyzed. The loading device may permit each of the plurality of cassettes to be independently interchanged with a separate cassette removably constraining a separate plurality of probes during mass spectrometric analysis, or for additional cassettes to be loaded into the device during analysis. In a useful embodiment, the loading device comprises a cassette transport assembly and a probe insertion assembly. The cassette transport assembly linearly translates one or more cassettes to align the cassette(s) with respect to the mass spectrometer so that a probe may be translated therebetween by the probe insertion assembly.Type: GrantFiled: February 25, 2003Date of Patent: March 15, 2005Assignee: Ciphergen Biosystems, Inc.Inventors: Scott M. DeWinter, John B. Rusconi, Steven M. Clark, Michael P. Lucas, Michael G. Youngquist

Patent number: 6795602Abstract: A fiber optic switch (400) includes a fiber optic switching module (100) that receives and fixes ends (104) of optical fibers (106). The module (100) includes numerous reflective light beam deflectors (172) which may be selected as pairs for coupling a beam of light (108) between a pair of optical fibers (106). The module (100) also produces orientation signals from each deflector (172) which indicate its orientation. A portcard (406) included in the switch (400) supplies drive signals to the module (100) for orienting at least one deflector (172). The portcard (406) also receives the orientation signals produced by that deflector (172) together with coordinates that specify an orientation for the deflector (172). The portcard (406) compares the received coordinates with the orientation signals received from the deflector (172) and adjusts the drive signals supplied to the module (100) to reduce any difference between the received coordinates and the orientation signals.Type: GrantFiled: December 1, 2000Date of Patent: September 21, 2004Inventors: Armand P. Neukermans, Timothy G. Slater, Tyler L. Baughman, James P. Downing, John S. Forker, Gregory A. Reznick, Sam Calmes, Steven M. Clark, Jack D. Foster, Marc R. Schuman, Rajiv Ramaswami

Patent number: 6592735Abstract: A machine for sequencing DNA using optical techniques. A sample is loaded in the sample loading area, and place through DNA sequencing gel. The voltage across the reservoir may be increased by improving the cooling and thermal characteristics of the gel device. Preferably materials are used which have at least half and preferably a fifth the thermal transfer characteristics of glass. The materials can also be thin e.g. 50-100 microns. A heat sink can be used to dissipate more of the heat, and a fan can be directed at the heat sink. Moreover, the material can be flexible.Type: GrantFiled: December 22, 2000Date of Patent: July 15, 2003Assignee: California Institute of TechnologyInventors: Joseph T. Meier, Steven M.

Patent number: 5219099Abstract: A syringe pump, uses a stepping motor to rotate a lead screw with precision and in turn advance a zero-backlash ball nut or vice-versa to drive the syringe plunger. This invention is designed to eliminate virtually all forces that are not coaxially aligned with the plunger's axis by utilizing a drive shaft kinematically supported on a reference member. The barrel of the syringe is kinematically supported on the reference member with its axis aligned with the axis of the drive shaft. The drive shaft is advanced by the ball nut and drive shaft assembly to drive the plunger which is kinematically supported at one end by the end of the drive shaft and at the other end by the internal wall of the barrel.Type: GrantFiled: September 6, 1991Date of Patent: June 15, 1993Assignee: California Institute of TechnologyInventors: Charles F.

Patent number: 5084157Abstract: An apparatus for separating particles within a medium which is capable of generating electric fields having adjustable magnitudes and orientations is disclosed herein. The electrophoretic apparatus of the present invention includes electrode arrangement for providing a plurality of sets of opposing individually responsive electrodes for generating electric fields within the medium, each field having at least one magnitude and direction. The invention further includes a control circuit for selectively controlling electrodes within the electrode sets to vary the magnitudes and directions of the electric fields at locations within the medium. The electric fields induce differing rates of motion of the particles thereby separating the particles.Type: GrantFiled: March 21, 1988Date of Patent: January 28, 1992Assignee: California Institute of TechnologyInventors: Steven M.
