Patent number: 6844419Abstract: Optics used in a high vacuum environment are mounted by bonding by use of addition polymerizing material which used in that environment. The suitability for use in the high vacuum environment is achieved by precise control of outgassing of trapped and dissolved gases, including low molecular weight hydrocarbons and amines, and unreacted material from component parts of said addition polymerizing material. A plurality of application quantities of the polymer are prepared in a large batch for use as pre-mixed frozen (PMF) material. The use of the large batch enables more precise control of mixture so that near-stoichiometric proportions of the polymer components are easily achieved.Type: GrantFiled: December 7, 2001Date of Patent: January 18, 2005Assignee: Agilent Technologies, Inc.Inventors: Vijaya N.

Patent number: 6845115Abstract: The CRCSEL comprises a single-mode optical gain structure and an optically-resonant cavity. The single-mode optical gain structure is structured to generate excitation light having a wavelength and a direction. The optically-resonant cavity is optically coupled to the single-mode optical gain structure and is structured to emit an output light beam in a direction substantially orthogonal to the excitation light. The change in light direction provided by the optically-resonant cavity enables the output light beam to emit from a surface while allowing the excitation light to be generated in a large, high-gain single-mode optical gain structure.Type: GrantFiled: December 5, 2002Date of Patent: January 18, 2005Assignee: Agilent Technologies, Inc.Inventors: Curt A.

Patent number: 6842608Abstract: The response of a receiver is calibrated using frequency-shifted stimulus signals. A source provides a stimulus signal that has a non-zero bandwidth and an adjustable spectral position. A signal path coupled between the source and the receiver introduces distortion to the stimulus signal. The receiver acquires a first digital representation of the stimulus signal at an output of the signal path with the stimulus signal adjusted to a first spectral position and acquires a second digital representation of the stimulus signal at the output of the signal path with the stimulus signal adjusted to a second spectral position that is shifted from the first spectral position by a predetermined frequency offset. A processor, designates the distortion introduced to the stimulus signal by the signal path to be equivalent at the first spectral position and the second spectral position.Type: GrantFiled: October 10, 2001Date of Patent: January 11, 2005Assignee: Agilent Technologies, Inc.Inventor: Robert T.

Patent number: 6841411Abstract: A method of forming an image sensor array uses a transparent top conductive layer first as an etch mask in forming inter-pixel trenches and then as an etch stop in a planarization step, whereafter the top conductive layer is integral to operation of the completed image sensor array. During fabrication, a stack of layers is formed to collectively define a continuous photosensitive structure over an array area. The operationally dependent transparent top conductive layer is then used in the patterning of the photosensitive structure to form trenches between adjacent pixels. An insulating material is deposited within the trenches and the top conductive layer is then used as the etch stop in planarizing the insulating material. The method includes providing a connectivity layer that provides electrical continuity along the patterned top conductive layer.Type: GrantFiled: June 30, 2003Date of Patent: January 11, 2005Assignee: Agilent Technologies, Inc.Inventor: Ronnie P.

Patent number: 6842614Abstract: A network analyzer is capable of measuring the antenna return loss in a live cellular network. The network analyzer receives and analyzes the base station transmitted signal to determine which transmit frequencies are active. Based on information relating to the correlation between the transmit frequency and the associated receive frequency, the network analyzer determines the active receive frequencies. An unmodulated source that avoids inclusion of the active receive frequencies is generated by the network analyzer. To fill in the antenna sweep with the previously avoided frequencies, the network analyzer generates another source containing only those avoided frequencies when no calls are active on the avoided frequencies. Alternatively, the antenna return loss on the avoided frequencies is interpolated from the measured frequencies.Type: GrantFiled: February 4, 2002Date of Patent: January 11, 2005Assignee: Agilent Technologies, Inc.Inventor: Terrence R. Noe

Patent number: 6841131Abstract: What is described in this case is a laboratory microchip having microspray means whose direction of spray can be altered. The microchip has a substrate 40 which has a channel structure provided on one side 41 thereof. On the other side (in the region of an edge of the substrate in the present case), there is a microspray tip 42. Substrate 40 is designed to be deformable particularly in a region 43, in which case the deformability may be achieved either by thinning the substrate material locally in this region 43 or by means of a linear perforation extending approximately perpendicularly to the plane of the paper. Alternatively, the deformability may be obtained by selecting a suitable material for the entire substrate. A microchip which has been bent in the manner indicated is shown in the bottom part of FIG. 3. The bending of the substrate which is shown has turned the direction of spray 44 of microspray tip 42 through 90°. The bending of the substrate may be permanent or reversible in this case.Type: GrantFiled: November 8, 2002Date of Patent: January 11, 2005Assignee: Agilent Technologies, Inc.Inventors: Hans-Peter Zimmermann, Gerhard Plé
