An electronic imaging sensor. The sensor includes an array of photo-sensing pixel elements for producing image frames. Each pixel element defines a photo-sensing region and includes a charge collecting element for collecting electrical charges produced in the photo-sensing region, and a charge storage element for the storage of the collected charges. The sensor also includes charge sensing elements for sensing the collected charges, and charge-to-signal conversion elements. The sensor also includes timing elements for controlling the pixel circuits to produce image frames at a predetermined normal frame rate based on a master clock signal (such as 12 MHz or 10 MHz). This predetermined normal frame rate which may be a video rate (such as about 30 frames per second or 25 frames per second) establishes a normal maximum per frame exposure time. The sensor includes circuits (based on prior art techniques) for adjusting the per frame exposure time (normally based on ambient light levels) and novel frame rate adjusting features for reducing the frame rate below the predetermined normal frame rate, without changing the master clock signal, to permit per frame exposure times above the normal maximum exposure time. This permits good exposures even in very low light levels. (There is an obvious compromise of lowering of the frame rate in conditions of very low light levels, but in most cases this is preferable to inadequate exposure.) These adjustments can be automatic or manual.

In a microfluidic system, a magnetic clamp for sealing a flexible microchannel chip includes a base formed from a magnetically-attractable material. The base supports a window for viewing the face of the microfluidic chip. A ring with magnets uniformly distributed around it is disposed over the base. A transparent disk attached to the top of the ring has an inlet and an outlet for introducing and removing a fluid medium into a cavity defined the disk, the window, the center opening of the ring and the base. An elastomer cushion is attached to the inner surface of the disk. The magnetic force between the base and the magnets on the ring compresses the cushion against the microfluidic chip so that the microchannels are sealed against the window with a uniform and reproducible pressure.

A connector plug terminates a communication cable having a plurality of conductors therein. The plug includes a conductor organizing sled, which includes a plurality of channels for separating conductive wires. The sled is formed of at least two materials, including a first material being a conductive material and a second material being a dielectric material. The first material may be a metal and the second material may be a plastic. In one embodiment, the first material is impregnated within at least a portion of the second material. In another embodiment, the first material is formed as a layer on an outer surface of at least a portion of the second material.

A transparent dielectric composition comprising tin, oxygen and one of aluminum or magnesium with preferably higher than 15% by weight of aluminum or magnesium offers improved thermal stability over tin oxide with respect to appearance and optical properties under high temperature processes. For example, upon a heat treatment at temperatures higher than 500 C, changes in color and index of refraction of the present transparent dielectric composition are noticeably less than those of tin oxide films of comparable thickness. The transparent dielectric composition can be used in high transmittance, low emissivity coated panels, providing thermal stability so that there are no significant changes in the coating optical and structural properties, such as visible transmission, IR reflectance, microscopic morphological properties, color appearance, and haze characteristics, of the as-coated and heated treated products.

A scroll machine is powered by a brushless permanent magnet motor. The rotor for the motor includes a rotor body formed by a plurality of laminations and an upper and lower counterweight made of zinc and located at opposite ends of the rotor body. An attachment member extends through the counterweights and the rotor body to secure the counterweights and the plurality of laminations. The counterweights include steel inserts which cooperate with the attachment member to provide a metal to metal clamping for the rotor body with a steel connection being maintained through the rotor.

To provide a bearing device for a wheel, in which a preload control is easy and a uniform amount of preload can be applied with a bearing seal being mounted, the bearing device for the wheel includes an outer member, an inner member and double rows of rolling elements interposed between the outer member and the inner member. The outer member has a flange on an outer periphery thereof and also has an inner periphery formed with two rolling surfaces. The inner member is formed with rolling surfaces opposed to the rolling surfaces of the outer member. The double rows of the rolling elements are interposed between the rolling surfaces of the outer member and the inner member. A sensor for detecting the amount of preload of the bearing is provided in one of the outer and inner members.

An apparatus for drawing a glass ribbon including a shroud surrounding the glass ribbon and an edge roll that penetrates the shroud to contact the glass ribbon. The apparatus includes regulating a pressure within the seal assembly to be equal to or less than a pressure within the shroud and prevent ingress of relatively cooler outside gas into the hot interior of the shroud. The edge roll utilizes an air bearing to minimize friction that can produce periodic fluctuation of the ribbon as the edge roll is displaces in response to variations in the ribbon thickness or equipment dimensions.

Electrode structures, variable resistance memory devices, and methods of making the same, which minimize electrode work function variation. Methods of forming an electrode having a minimized work function variation include methods of eliminating concentric circles of material having different work functions. Exemplary electrodes include electrode structures having concentric circles of materials with different work functions, wherein this difference in workfunction has been minimized by recessing these materials within an opening in a dielectric and forming a third conductor, having a uniform work function, over said recessed materials.

The invention is directed to optical sensors for measuring clinically relevant analytes, their methods of manufacture, and their various uses. In an effort to develop a dry calibration method for the optical sensors of the invention it is discovered that water content inside or in the immediate vicinity of a such a sensor can have a major impact on fluorescence intensity (i.e., a sensor's response in the dry state). Thus, one of the objectives of the invention is the elimination of the bias of sensor responses measured at different humidity environments.

A light source system and method that generates stable optical power over time and temperature for use in laser scanning, turbidity sensing, airborne-particle analysis, fog and visibility monitoring, blood-gas analysis and applications where light source output intensity changes less than one-half percent over a 50° C. range. The system includes a miniature semiconductor light emitter that can be powered by two AAA alkaline batteries for more than 100 hours and is about 1 cm³ in size (TO-5 package). A semiconductor light emitter emits a beam of linearly polarized light through a coated optical element having first and second surfaces that meet at an acute angle, the first surface reflecting a portion of the light to a control system and transmitting the rest through the second surface in a direction normal to it and thereby enabling immunity to light interference in the reflected and transmitted beams and novel, error-canceling properties.
