摘要： A receiver and method for using the same to process optical signals is disclosed. The receiver includes an optical coupler and a polarization dependent beam splitter. The optical coupler combines an input signal and a local oscillator signal into a first combined signal. The optical coupler includes a polarization filter that operates on the local oscillator to provide a linearly polarized signal having a predetermined LO polarization direction.

摘要： Apparatus for acquiring individual workpieces from a supply of randomly oriented workpieces in a storage bin or the like. The apparatus includes a movably mounted head assembly having a gripper connected thereto by an intermediate flexible support. A sensor generates a control signal responsive to a contact force exerted by the gripper on a workpiece. The gripper operates to grip the workpiece contacted thereby. The flexible support is then retracted to lock the gripper against an abutment surface fixed relative to the head assembly. Operation of the gripper and/or movement of the head assembly may be controlled in response to said control signal.

摘要： Non-contact fluid deposition devices having multiple axis printhead adjusters are provided. The subject printhead adjusters are made up of a single rigid frame that holds at least one printhead housing, where in certain embodiments multiple printhead housings, e.g., two, are held in side-by-side configuration in the single rigid frame of the adjuster. Each housing is adjusted in said adjuster by its own set of axis adjustment elements, where the set includes a rotational axis adjustment element for each horizontal and/or vertical axis adjustment element that is present. In using the subject devices, a printhead present in the adjuster is loaded with a volume of fluid, which in many embodiments is a fluid that includes a biopolymer or precursor thereof. The loaded printhead is then placed in opposing relation to a surface of a substrate and actuated to deposit a volume of fluid on the substrate. Prior to fluid loading and/or deposition, the printhead is typically adjusted with the set of axis adjustment elements. The subject invention finds use in a variety of applications, including the production of biopolymeric arrays.

摘要： The invention provides an apparatus for producing an image of a global surface of an ion source sample plate that is exterior to an ion source. In general terms, the apparatus contains a sample plate for an ion source, an imaging device (e.g., a CCD or CMOS camera) and an illumination device that is configured to produce a light beam that contacts the sample plate surface to define a grazing angle between the light beam and the sample plate surface. The apparatus may be present at a location that is remote to the ion source.

The drop deposition apparatus has a drop dispenser unit and a sensing element. The method comprises includes for each of multiple addresses, dispensing droplets carrying the biopolymers or biopolymer precursors from a drop dispenser unit onto the sensing element, and onto the substrate so as to fabricate the array. Electrical signals resulting from dispensed droplets striking the sensing element are detected. A performance characteristic of the deposition apparatus is evaluated based on the detected signals.
