Abstract: The purification of monoalkyl tin trialkoxides and monoalkyl tin triamides are described using fractional distillation and/or ultrafiltration. The purified compositions are useful as radiation sensitive patterning compositions or precursors thereof. The fractional distillation process has been found to be effective for the removal of metal impurities down to very low levels. The ultrafiltration processes have been found to be effective at removal of fine particulates. Commercially practical processing techniques are described.

Abstract: In one embodiment, a lidar system includes a wavelength-tunable light source configured to emit pulses of light, each emitted pulse of light having a particular wavelength of multiple different wavelengths. The lidar system also includes a scanner configured to scan the emitted pulses of light across a field of regard of the lidar system. The scanner includes (i) a beam deflector configured to angularly deflect each emitted pulse of light along a first scan axis according to the particular wavelength of the emitted pulse of light and (ii) a scan mirror configured to scan the emitted pulses of light along a second scan axis different from the first scan axis. The lidar system further includes a receiver configured to detect a received pulse of light that includes a portion of one of the emitted pulses of light scattered by a target located a distance from the lidar system.

Abstract: Instrument control and data acquisition in advanced analytic systems that utilize optical pulses for sample analysis are described. Clocking signals for data acquisition, data processing, communication, and/or other data handling functionalities can be derived from an on-board pulsed optical source, such as a passively mode-locked laser. The derived clocking signals can operate in combination with one or more clocking signals from a stable oscillator, so that instrument operation and data handling can tolerate interruptions in operation of the pulsed optical source.

Abstract: A waste disposal apparatus, such as a waste disposal container or unit that is configured to receive used personal care products in a discreet and sanitary manner Instances of incontinence, menstruation or uncontrollable bodily functions can be a personal situation that is otherwise unknown to others. However, current receptacles available to dispose of used personal care products fail to provide for a hygienic, easily accessible and discreet that is designed for small spaces, such as a home bathroom or public restroom stall.

Abstract: A container for holding a fluid that includes a hollow body defining an inner volume and an elastomeric membrane that is integrally formed with the hollow body forming a unitary container having a vent area. The vent area vents the inner volume such that air is selectively permitted to flow into the inner volume through the vent area and the fluid contained in the inner volume is substantially prevented from flowing out of the inner volume through the vent area. The elastomeric membrane is co-molded with the hollow body.

Abstract: There is provided a spill proof cup assembly having a cap with at least one spout outlet, a cup with an upper open portion adapted to securely and sealingly receive the cap, and a thermoplastic elastomer, or similar elastomeric material, co-molded bottom portion with a vent disposed therein for allowing air to enter the cup as fluid exits through the spout outlet. The result is a one-way flow of air.

Abstract: A high speed desk top MICR printer for financial transaction documents and the like. The print wheel is stepped at a selectively variable rate determined by the number of required angular steps between consecutive printed characters. The step rate is selected to maximize print wheel acceleration and deceleration without loss of stepper motor synchronization.
