Patent number: 8176607Abstract: A method for fabricating VHF and/or UHF quartz resonators (for higher sensitivity) in a cartridges design with the quartz resonators requiring much smaller sample volumes than required by conventional resonators, and also enjoying smaller size and more reliable assembly. MEMS fabrication approaches are used to fabricate with quartz resonators in quartz cavities with electrical interconnects on a top side of a substrate for electrical connection to the electronics preferably through pressure pins in a plastic module. An analyte is exposed to grounded electrodes on a single side of the quartz resonators, thereby preventing electrical coupling of the detector signals through the analyte. The resonators can be mounted on the plastic cartridge or on arrays of plastic cartridges with the use of inert bonding material, die bonding or wafer bonding techniques. This allows the overall size, cost, and required biological sample volume to be reduced while increasing the sensitivity for detecting small mass changes.Type: GrantFiled: October 8, 2009Date of Patent: May 15, 2012Assignee: HRL Laboratories, LLCInventors: Randall L.

Patent number: 7653985Abstract: Disclosed are methods for fabricating a micro-electro-mechanical switch. The switch has a cantilever arm disposed on a substrate that can be moved in orthogonal directions for latching and unlatching. For latching, the cantilever arm is moved back by a comb-drive actuator and then pulled down by electrodes disposed on the substrate and the cantilever arm. The comb-drive actuator switch is then released and the cantilever arm moves forward to be captured by a dove-tail structure on the substrate. When the voltage is removed, the cantilever arm is held in place by the dove-tail structure. The switch is unlatched by actuating the comb-drive actuator to move the cantilever arm away from the dove-tail structure. The cantilever arm will then pop up once it is released from the dove-tail structure.Type: GrantFiled: June 27, 2007Date of Patent: February 2, 2010Assignees: HRL Laboratories, LLC, BoeingInventors: David T.

Patent number: 7629194Abstract: Apparatus for a micro-electro-mechanical switch that provides single pole, double throw switching action. The switch has two input lines and two output lines. The switch has a seesaw cantilever arm with contacts at each end that electrically connect the input lines with the output lines. The cantilever arm is latched into position by frictional forces between structures on the cantilever arm and structures on the substrate in which the cantilever arm is disposed. The state of the switch is changed by applying an electrostatic force at one end of the cantilever arm to overcome the mechanical force holding the other end of the cantilever arm in place.Type: GrantFiled: August 27, 2007Date of Patent: December 8, 2009Assignee: HRL Laboratories, LLCInventors: James H.

Patent number: 7427961Abstract: A method for improving the efficiency of antennas having transparent thin-film conductive surfaces, and antennas improved by the method are disclosed. For a selected frequency of antenna operation, values for surface current density in areas distributed over the surface of the thin-film are determined. Regions of the surface containing areas having concentrated current flow are identified based upon the determined values of current density. Antenna efficiency is improved by increasing conductivity in areas of the thin-film surface found to have concentrated current flow. The method enables the improvement of the efficiency of antennas having transparent thin-film conducting surfaces, without unnecessarily obstructing the optical view through the thin-film surfaces of the antennas.Type: GrantFiled: August 2, 2007Date of Patent: September 23, 2008Assignee: GM Global Technology Operations, inc.Inventors: Hyok J.

Patent number: 7405641Abstract: A micro-electro-mechanical switch is described. The switch comprises a substrate, with a signal transmission portion and an activation portion attached with the substrate. The activation portion includes an armature activation electrode positioned above a substrate activation electrode. The signal transmission portion includes a metal contact extending from a conducting transmission line and through a bottom insulating layer of the signal transmission portion, thereby being exposed for electrical contact.
