Abstract: The present invention is broadly concerned with a vaccine composition comprising a central carrier, at least one linear carbohydrate molecule, and at least one immunogen molecule, wherein each of the at least one linear carbohydrate molecule and at least one immunogen molecule are covalently bound to the carrier via respective covalent linkages. Vaccine compositions comprising multivalent carriers and related methods may find various therapeutic and prophylactic applications for inducing an immune response against, treating, or preventing a bacterial, viral, fungal, or protozoan infection, including, but are not limited to, coronaviruses, Lyme Disease, Chlamydia, and the related diseases thereof.

Abstract: Vaccine compositions comprising at least one modified immunogen via in vitro glycosylation methods that provide a rational approach for generating glycosylated versions of immunogens via the reducing end of a linear carbohydrate, the reducing end containing an N-acyl-2-amino moiety. Vaccine compositions comprising a plurality of heterologous immunogens associated with a multivalent carrier, wherein at least one immnunogen is glycosylated. Vaccine compositions comprising multivalent carriers and related methods using the vaccine compositions in various therapeutic and prophylactic applications for inducing an immune response against, treating, or preventing a bacterial, viral, fungal, or protozoan infection.

Abstract: An in-floor electrical fitting includes a lower body, an upper body detachably connected to the lower body, and at least one detachable retention clip movable between a first position in which a portion of the at least one detachable retention clip extends outwardly past a periphery of the body and a second position in which the portion of the at least one detachable retention clip is moved inward from the periphery of the body. An angular position of the upper body may be reconfigurable relative to the lower body into at least two different orientations.

Abstract: The invention relates to an image forming media composition including an infrared reflecting pigment. The infrared reflecting pigment may be one that substantially absorbs light in the visible spectrum of about 400-700 nanometers and reflects greater than about 5.0% of light within the wavelength of about 700-2500 nanometers. The infrared reflecting pigment may therefore be combined with pigments such as carbon black in a toner formulation and provide the ability to control toner thickness level within a device such as a toner patch sensor.

Abstract: Control circuitry associated with an electrophotographic imaging device is adapted to operate in conjunction with a sensor to adjust operating parameters, including an imaging power. The sensor detects a reflectivity of a developed image and the control circuitry uses this detected information and information related to reflectivity of the underlying surface and the developing toner to determine whether the developed image is produced as desired. The control circuitry adjusts imaging power in response to a comparison between the detected reflectivity and a target reflectivity. In one embodiment, a predetermined halftone pattern is developed over a range of imaging powers and an optimum operating point is determined from the iterations. A predictive model may be generated based on many data points to select imaging power based on optimized surface potentials.

Abstract: Control circuitry associated with an electrophotographic imaging device is adapted to operate in conjunction with a sensor to adjust a difference in electrical bias between a photoconductive surface and an associated roller. The sensor detects a reflectance or luminosity of a developed image and the control circuitry uses this detected information and information related to reflectance or luminosity of the underlying surface and the developing toner to determine whether the developed image is produced as desired. The control circuitry adjusts the difference in electrical bias between the photoconductive surface and an associated roller in response to a comparison between the detected and desired images. In one embodiment, a predetermined test pattern is developed over a range of electrical bias differences and an optimum operating point is determined from the iterations.

Abstract: A temperature compensated doctor blade system is disclosed for controlling the amount of liquid on a substrate. Variation in temperature is found to cause wide variation in liquid viscosity which affects doctor blade pressure requirements. An expandable chamber containing a temperature responsive fluid is used to control the pressure applied to a flexible doctor blade.
