Abstract: A compressor design includes a male rotor (10) having one or more helical lobes (12) and a female rotor (14) having one or more helical grooves (16). The male rotor is mounted on a first shaft and the female rotor is mounted on a second shaft. The male rotor is positioned in a first section of a chamber and the female rotor is positioned in a second section of the chamber. Fluid enters the chamber at an inlet, and when the rotors are driven, the lobes of the male rotor fit into the grooves of the female rotor, causing compression and movement of the fluid towards an outlet or discharge end where the compressed fluid is discharged. The configuration of the lobe and groove helix, the lobe and groove profile, and the outer diameter of the rotors can be varied in different combinations to form different rotors.

Abstract: A smart biochip array comprises an array of test sites disposed on a substrate and a smart circuit operatively associated with the substrate. Each test site contains a distinct type of probe molecule, and the smart circuit includes a memory that stores data identifying which distinct type of molecule is stored in each test site. The test sites in the biochip array are exposed to a sample that may contain target molecules capable of binding with probe molecules contained in one or more test sites. A system for scanning the exposed smart biochip array includes a detector for detecting binding between probe molecules and target molecules in each test site and a reader for reading data from the smart circuit, including data identifying the type of probe molecules contained in each test site.

Abstract: An apparatus (10) for visually aligning parts (13) for placement using one camera (18) comprises a device (12) for picking and placing a part on an object (15), a device (24, 26 & 28) for moving and removing optics (30, 36, 38) into and out of a work envelope having the object, a device (18, 40, 42 & 44) for locating landmarks on the object within the work envelope, and a device for aligning the part with the landmark in the work envelope.

Abstract: An apparatus (100) for correcting misalignments in a robotic assembling devices has a first shaft (102) having a ferrous material (120) and a second shaft (104) having a magnetic material (122). The first and second shafts (102, 104) are magnetically coupled, and a motion on the first shaft (102) is provided to the second shaft (104) which corrects misalignments between the magnetic coupling (112) of the first and second shafts (102, 104).

Abstract: A circuit assembly device (200) comprises a cylinder (202) containing a piston (204) coupled to an end-effector for facilitating an assembly of a circuit carrying substrate. The piston (204) defines a first chamber (212) and a second chamber (214) in the cylinder (202) for maintaining substantially the same pressure such that a difference in areas of the first and second chambers (212, 214) establishes a compliant force on the end-effector.

Abstract: A housing (100), that is suitable for use in a automated manufacturing and/or testing environment, is constructed and arranged to substantially enclose and shield a trimmable electrical circuit (107) from radio frequency interference external to the housing (100). At least a portion of the housing (100) is constructed and arranged to shield while contemporaneously allowing a laser beam (114) to pass therethrough so as to focus on at least a portion of the trimmable electrical circuit (107) and thereby laser trim the trimmable electrical circuit (107).
