Abstract: An orthodontic device for retaining teeth in position, or for making minor adjustments to tooth position. The dental retainer includes a rigid lingual portion or arch, and a more flexible and comfortable labial portion or arch, arranged so as to allow the cutting surfaces of the upper and lower molar teeth to meet. Small protrusions of harder material may be located on the inner surface of the labial portion to fit between the teeth in order to prevent relapse of tooth position.

Abstract: In an embodiment, a pad for use with a phototherapy system includes a first plastic layer having a surface facing the user in a central region. The first plastic layer defined by a peripheral edge has an average percent light transmission in a 440 nm to 480 nm band of at least 85%. A second plastic layer has the same structure and light transmission properties. The peripheral edges are connected. The first and second plastic layer central regions are spaced apart forming a closed cavity. The first and second plastic layer central regions are also connected forming a thermal bridge and dividing the cavity into a plurality of subcavities that fluidly communicate. The cavity includes a fluid medium having average percent light transmission of at least 85%. The combination of first and second plastic layers and fluid is sufficiently flexible to form a 2-T bend or tighter.

Abstract: A phototherapy device and method for treating neonatal hyperbilirubinemia (jaundice) and related conditions. The device comprises a flexible material at least partially encasing flexible circuitry that allows the device to flex as an infant is positioned on it, while, also protecting the circuitry. The circuitry comprises a plurality of light emitting diodes (LEDs) mounted within flexible circuitry, means for altering the duty cycle of the LEDs, and wiring to connect the circuitry to a power supply. The device further comprises a multilayer film that encases all of the circuitry, the flexible material, and LEDs to facilitate sterilization in both long-term or short-term use.

Abstract: A paper machine configured as a swing machine capable of producing both light and heavy grades providing a Yankee hood split into a wet end half and a dry end half, at least one hood half being a flex-hood half wherein the supply for that half is capable of being run with either combustion heat or recycled heat and is capable of either recirculating the exhaust from the hood or discharging it to the atmosphere. The heater for the flex-hood half comprises both a primary combustion heat source and an indirect heat source capable of extracting by-product heat from another operation. The exhaust system for the flex hood half is capable of being run in either a straight through mode or in a recirculating mode.

Abstract: A machine and method for high speed production of circuit patterns on silicon wafers or similar substrates may be used for applications including printing Integrated Circuit (IC) packaging patterns onto wafers prior to separating IC chips. Projection camera(s) simultaneously project image(s) onto substrate(s) carried on an X, Y, ? stage. The projection camera(s) may include independent alignment systems, light sources, and control of focus, image placement, image size, and dose. In one embodiment, each camera inlcudes a 6-axis reticle chuck that moves a reticle to correct image-to-substrate overlay errors. In-stage metrology sensors and machine software establish and maintain the correct relationship among the machine's coordinate systems. Thus, two or more projection cameras can print simultaneously even when substrates are slightly misplaced on the X, Y, ? stage.
