Abstract: The present disclosure describes a digital-to-analog converter (DAC) comprising a programmable integrated circuit, a resampler, and a clock. The programmable integrated circuit may be configured to perform delta-sigma modulation to convert a digital signal to a coarse representation of an analog signal. The coarse representation of the analog signal may be sent to a first-stage of the resampler. After processing the signal, the first-stage of the resampler may pass a continuous signal to the second-stage of the resampler. The second-stage of the resampler produce a clean sampling instant for the signal that represents the point in time where the signal transitions from discrete time to continuous time. The analog signal may then be outputted to one or more receivers.

Abstract: An open-architecture system automatically consolidates information from a plurality of financial systems into a single accounting system without the need for expensive and time-consuming backroom procedures. The system enables an entity to use multiple independent and potentially incompatible financial systems to facilitate, control and monitor its spending, purchasing and other financial activities, while also enabling the entity to monitor and control all of these activities in real time. The system receives, processes and stores information obtained from a plurality of financial and/or other external computerized systems, and provides one or more authorized users with the ability to monitor financial transactions on-line and manipulate and control all financial transactions of the entity in real time using, for example, Web-browser software technology. Different users may have different levels of access to the financial transaction data obtained, processed and stored by the system.

Abstract: A shower installation in which a monolithic stone slab serves as the floor, or pan, of the installation. A liner of plastic material seated beneath the stone slab, the liner in the stone slab each having an aperture therein for receipt of a drain assembly. The liner is formed with an array of channels in the upper surface thereof, all of which slope toward the drain opening in order that fugitive moisture and condensation accumulated beneath the stone slab be directed away from the stone slab and into the drain.

Abstract: A family of reflectin proteins is identified herein that is deposited in flat, structural platelets in reflective tissues of the squid Euprymna scolopes. These proteins are encoded by at least six genes in three subfamilies and have no reported homologues outside of squids. Reflectins possess 5 repeating domains, that are remarkably conserved among members of the family. The proteins have a highly unusual composition with four relatively rare residues (tyrosine, methionine, arginine, and tryptophan) comprising ˜57% of a reflectin, and several common residues (alanine, isoleucine, leucine, and lysine) occurring in none of the family members. These protein-based reflectors in squids provide a striking example of nanofabrication in animal systems.

Abstract: Ultrasonic processing apparatus and methods are disclosed, which includes multiple transducers of at least two different resonant frequencies supplying ultrasonic energy to a liquid filled tank containing components to be cleaned or processed ultrasonically. The transducers are arranged in equilateral triangular patterns along diagonal lines on a wall of the tank so that each transducer has an adjacent transducer of a different frequency. Alternatively, the apparatus includes one or more rod transducers having different resonant frequencies so that the apparatus provides a mixture of various frequencies of ultrasonic energy to the tank. Another aspect of the invention involves selecting transducers with different resonant frequencies that are outside an excluded subrange, and powering the transducers by a driving signal that sweeps through the resonant frequencies of the transducers and the excluded subrange.
