Abstract: One example provides a method of operating a time-of-flight camera system comprising an illumination source and an image sensor. The method comprises operating the illumination source and the image sensor to control a plurality of integration cycles and a plurality of readout cycles. In each integration cycle, the method comprises performing a plurality of pulse width modulated (PWM) illumination cycles where each PWM illumination cycle is separated from one or more adjacent PWM illumination cycles by a non-illumination cycle. For each PWM illumination cycle, the method comprises directing photocharge to in-pixel memory for each pixel that is performing image integration and for each non-illumination cycle conducting photocharge away from the in-pixel memory for each pixel that is performing image integration. The readout cycle comprises, for each pixel that performed image integration, reading a charge stored in the in-pixel memory after the integration cycle.

Abstract: Novel streamwater remediation systems and processes are presented. The disclosed systems involve design and placement of geometric volumes of porous media of variable hydraulic conductivity within the streambed to enhance hyporheic exchange (exchange of water from the stream or constructed urban waterway compartment to the porous media, or streambed, compartment). The disclosed systems may help improve water quality in various ways, for example through the removal of contaminants from water as it passes through the streambed. In some embodiments, contaminant removal is achieved by microbes and/or reactive geomedia incorporated into the streambed structures. By pairing hydrologic/flow structures with bacteria or reactive geomedia, diverse contaminants such as metals, nutrients, organics, pathogens, and more can be sorbed, deactivated, assimilated, transformed to harmless chemicals, and otherwise removed from the water.

Abstract: An automated system and method for processing prescription requests is disclosed, whereby a patient or physician enters a prescription request to an automated pharmacy prescription processing system. For example, a request for a new or refill prescription can be transmitted from a physician's office to the prescription processing system as a digital file or facsimile message, or using keypad or voice commands in an Interactive Voice Response (IVR) system running in the prescription processing system. A request for a prescription refill can also be entered by a patient using an IVR system, or the patient can physically carry the refill prescription request to a pharmacy for entry to the prescription processing system by a technician. The automated pharmacy system determines whether the new or refill prescription request can be filled by a central fill inventory.

Abstract: Pollutants are extracted from sub-surface water using an aqueous solution of cyclodextrin and a vertical circulating well. Complexes of the pollutant and cyclodextrin are recovered from the bottom of the well. When the pollutant is volatile, the complexes are separated into pollutant and cyclodextrin by air stripping.

Abstract: A fluid control valve is described having a valve housing having first and second valve housing openings for the ingress and egress of fluid through the control valve. Disposed within a void formed by the control valve is a sleeve having at least one sleeve opening to permit the flow of fluid therethrough. A flow restricter travels within the sleeve to progressively block off the sleeve opening and thereby control flow. A fluid passageway is formed between the first valve housing opening and the outer surface of the sleeve. A second fluid passageway is formed between the inside of the sleeve and the second valve housing opening. Neither fluid passageway contains more than one 90.degree. turn. In the preferred embodiment only one of the two fluid passageways contains a 90.degree. turn. In another embodiment, the control valve housing is bifurcated by a control surface having control surface opening disposed therethrough.
