Abstract: This disclosure provides an ultra-compact and highly stable and efficient optical measurement system based on principals of optical absorption spectroscopy using substantially collinear pathways. It improves on such an emitter for gas sensing applications and utilizes it in a differential path-length configuration, in which two separate paths have different optical absorption coefficients by an analyte gas or molecule. The combination of two-color emission from the same source as well as two separate path lengths provides four independent measurements that can measure molecular concentration while cancelling out system fluctuations from temperature, humidity, stress, device aging, power, spectral shifts, as well as other environmental factors mechanics that would otherwise interfere with the measurement and limit sensitivity or require significant additional calibration.

Abstract: An adjustable pedal for a vehicle has readily accessible adjustment mechanisms. An adjustment component has a first leg and also has a cross leg secured in the passenger compartment of the vehicle. A slot extends horizontally in the first leg with horizontal first alignment holes above and below the slot. Bolts couple a slide block to the first alignment holes at a vertical position of comfort to a driver. A brake pedal has an upper end pivotably coupled to the slide block and has a lower end adapted to be depressed by the driver. A foot pad is coupled to the lower end of the brake pedal. A plurality of elevationally spaced holes are in the brake pedal. Bolts couple the foot pad to the brake pedal at a horizontal position of comfort for the driver.

Abstract: According to the invention, there is provided seed and plants of the corn variety designated LH333BT1. The invention thus relates to the plants, seeds and tissue cultures of the variety LH333BT1, and to methods for producing a corn plant produced by crossing a corn plant of variety LH333BT1 with itself or with another corn plant, such as a plant of another variety. The invention further relates to corn seeds and plants produced by crossing plants of variety LH333BT1 with plants of another variety, such as another inbred line. The invention further relates to the inbred and hybrid genetic complements of plants of variety LH333BT1.

Abstract: A method for accelerated leaching of binder-catalyst material from the polycrystalline diamond structure of a PDC is disclosed. The PDC is sonochemically leached. Also disclosed are fixture, equipment and a system for sonochemically leaching the polycrystalline diamond structure of a PDC.
