Abstract:

Entry of HIV-1 into target cells requires cell surface CD4 as well as additional host cell cofactors. A cofactor required for infection with virus adapted for growth in transformed T cell lines was recently identified and named fusin. Fusin, however, does not promote entry of macrophage-tropic viruses that are believed to be the key pathogenic strains in vivo. It has now been determined that the principal cofactor for entry mediated by the envelope glycoproteins of primary macrophage-tropic strains of HIV-1 is CC-CKR5, a receptor for the β-chemokines RANTES, MIP-1α, and MIP-1β.

International Classification:

H03H 7/00

US Classification:

333176, 333167

Abstract:

The present invention relates to a low pass filter incorporating coupled inductors to enhance stop band attenuation. In one embodiment, the coupled inductors are provided along with various capacitors to provide for superior performance within a smaller surface area of a semiconductor or ceramic integrated device. In a further specific embodiment, the capacitors are formed on an integrated device within an area on which entirely intertwined inductors are formed. In another embodiment, at least one further pair of coupled inductors is included to create additional frequency attenuation notches, as well as a wide stop-band.

International Classification:

H02H 9/00

US Classification:

361 56, 361 911, 361111, 361119

Abstract:

A method for implementing an inductor-capacitor filter in an integrated circuit. Embodiments of the invention implement a 5-pole LC low-pass filter suitable for incorporation in wireless applications necessitating compact layouts. Inductors are formed in an IC as concentric coils on metallization layers, the concentric coils providing a negative coupling coefficient between the inductors. The invention provides programmable frequency response characteristics, enabling the transmission of high-frequency base band information while attenuating carrier RF frequencies.

International Classification:

G06K 7/10

US Classification:

23546243, 235454, 23546201, 23546245, 23547201

Abstract:

Laser power monitoring arrangements interrupt power to a laser used in electro-optical readers upon detection of operating conditions not conforming to preestablished standards. An auxiliary light detector independently monitors the output power of a laser beam, and directly receives a portion of the laser beam reflected from a diffractive optical lens surface of an optical assembly for optically modifying the laser beam, or from a coated or uncoated inclined surface of a split collimating lens of the optical assembly. The split collimating lens may have its lens portions in mutual contact or separated by an air gap.

International Classification:

G06K 7/10

US Classification:

23546242, 23546201

Abstract:

The disclosed bar code reader has an imaging system that includes a light monitoring pixel array and a focusing lens that is fixed with respect to the pixel array for transmitting an image of the target object onto the pixel array. The bar code reader also includes an illumination system for illuminating the target having a light source for emitting a diverging light outwardly from a light source location and a lens for bending the light including a first surface facing the light source and a second surface facing the target for bending the light emitted by the light source to more uniformly illuminate a rectangular, generally planar region at the target within the barcode reader's field of view.

International Classification:

G06K 7/10

US Classification:

235455, 23547201, 235473, 235483, 235486

Abstract:

A laser power control arrangement and method in an electro-optical reader for reading indicia includes an energizable laser for emitting a laser beam having an output power along a path. An internal light detector, e. g. , a monitor photodiode, is mounted inside the laser for monitoring the output power of the laser. An external light detector, e. g. , an auxiliary photodiode, is mounted outside the laser for monitoring the output power of the laser independently of the internal light detector. A guide, advantageously a light pipe or a diffuser, is positioned outside the laser in the path of the laser beam for guiding the laser beam from the laser to the external light detector. A controller is operatively connected to each light detector, for controlling a monitored output power of the laser beam by deenergizing the laser when the monitored output power of the laser beam exceeds a safe power level limit.

International Classification:

G06K 7/10

US Classification:

23546242, 23546241

Abstract:

A module and an arrangement for, as well as a method of, generating a generally uniform distributed line pattern of light on a symbol to be read by image capture, include a light source for generating light along an optical axis in a distribution having different extents along intersecting directions generally perpendicular to the axis, and an optical component for receiving, and for optically modifying, the light from the light source to generate the generally uniform distributed line pattern of light on the symbol. The optical component includes a plurality of compound conic elements spaced apart from one another along one of the directions. Each compound conic element has a pair of conic segments for modifying the light along the one direction. A collimating lens modifies the light along the other of the directions. A solid-state imager has an array of image sensors for capturing return light from the symbol over a field of view having different extents along the intersecting directions.
