Publication number: 20240003801Abstract: System and methods are described herein for detecting positions or trajectories and/or controlling directions of charged droplets during travel. The systems and methods are useful for determining the locations of the charged droplets in real-time based on signals induced in the electrodes of a sensor surrounding an aperture through which the charged droplet passes in flight from the source well to the target. The signals from the sensor electrodes can be measured and used to determine a position or trajectory of the droplet. The systems and methods are useful for modifying trajectories of the charged droplets in real-time, such as based on determined positions identified as having a trajectory deviating from the target. The trajectories can be modified by applying voltages to electrodes surrounding an aperture through which the charged droplet passes in flight from the source well to the target.Type: ApplicationFiled: February 25, 2022Publication date: January 4, 2024Inventors: Lucien P.

Publication number: 20230290627Abstract: A system and method are provided for loading a sample into an analytical instrument using acoustic droplet ejection (“ADE”) in combination with a continuous flow sampling probe. An acoustic droplet ejector is used to eject small droplets of a fluid sample containing an analyte into the sampling tip of a continuous flow sampling probe, where the acoustically ejected droplet combines with a continuous, circulating flow stream of solvent within the flow probe. Fluid circulation within the probe transports the sample through a sample transport capillary to an outlet that directs the analyte away from the probe to an analytical instrument, e.g., a device that detects the presence, concentration quantity, and/or identity of the analyte. When the analytical instrument is a mass spectrometer or other type of device requiring the analyte to be in ionized form, the exiting droplets pass through an ionization region, e.g.Type: ApplicationFiled: March 14, 2023Publication date: September 14, 2023Applicants: Labcyte, Inc., DH Technologies Development Pte.

One surface is mechanically fixed, a second surface is free to move and deflections of the second surface relative to the first surface are monitored by optical interferometry. An optical fiber could be used to direct light from a light source to the sensor and collect light reflected by the sensor. Interaction of molecules or other objects in the sample with the second surface is detected as a change in amplitude and/or phase of deflection the second surface in response to an applied driving signal. A layer of binding molecules may be immobilized on the second surface and this surface exposed to a sample.Type: ApplicationFiled: August 27, 2012Publication date: December 20, 2012Inventor: Lucien P.

Patent number: 7227104Abstract: A device for producing patterns includes a thermal conductivity mask that has at least one cavity, a thin film positioned adjacent to the mask, and a heater which may be any convenient heat source. In a preferred embodiment, the thermal conductivity mask includes a pattern of cavities, holes or openings, and the thin film in held in tension over the mask. The cavities, holes or openings in the mask selectively control the flow of heat because they contain material having lower thermal conductivity than the material of the mask. The device may be used to transfer a pattern or image to a pancake, among other things.Type: GrantFiled: March 7, 2005Date of Patent: June 5, 2007Assignee: Lithoware, IncInventor: Lucien P. Ghislain

Patent number: 6896949Abstract: Improved optical element wafers comprising stacked, optically coupled etalon wafers are disclosed. Each etalon wafer comprises a bulk optic wafer defining the optic cavity between selectively transparent thin film mirror coatings. The bulk optic wafer comprises an optically transparent body, such as a portion of a substrate wafer, along with a wedge correcting coating on at least one of the two surfaces of the optically transparent body and/or a thickness-adjustment layer on one or both surfaces. The bulk optic wafer is a solid, self-supporting body, optically transparent (at the wavelength or wavelengths of interest), whose thickness, i.e., the dimension between the selectively transparent surfaces, defines the cavity spacing of the bulk optic etalon wafer. Methods of making and using the optical element wafers are also disclosed.Type: GrantFiled: March 12, 2002Date of Patent: May 24, 2005Assignee: Bookham (US) Inc.Inventors: Michael A.

Patent number: 6678093Abstract: Optical elements comprise stacked, optically matched and optically coupled etalons, at least one of the optically coupled etalons comprising first and second selectively transparent thin film mirror coatings on opposite surfaces of a bulk optic. The bulk optic defines the cavity spacing of the etalon and may, for example be formed of a monolithic body of silica or other optically transparent glass diced from a glass wafer. The bulk optic may further comprise a wedge coating of progressively increasing thickness overlying the monolithic glass body and compensating for, or offsetting non-parallelism of the bulk optic. The bulk optic may further comprise a thickness-adjustment layer of substantially uniform thickness. The disclosed optical elements optionally comprise other devices optically coupled to the stacked etalons. Novel methods are disclosed for producing the stacked etalons.Type: GrantFiled: March 12, 2002Date of Patent: January 13, 2004Assignee: Cierra Photonics, Inc.Inventors: Michael A. Scobey, Lucien P.

Patent number: 6658172Abstract: An optical system and method are disclosed for multiplexing or de-multiplexing channels within a wavelength band. The optical signals carried on the system comprise separate channels 1 through n, each having a unique passband and a center wavelength spaced from the center wavelength of adjacent channels by d nm. The signals are semi-multiplexed, demultiplexed, or semi-demultiplexed by an interleaver comprising optically matched and directly optically coupled etalons. Periodic spectral passbands of width less than d nm, spaced from each other a distance of zd, where z is an integer greater than or equal to 3, are substantially transmitted through the interleaver. At least one of the etalons is a bulk optic etalon and comprises first and second selectively transparent thin film mirror coatings on opposite surfaces of a bulk optic that defines the cavity spacing of that etalon.Type: GrantFiled: March 12, 2002Date of Patent: December 2, 2003Assignee: Cierra Photonics, Inc.Inventors: Michael A.
