Abstract: Cell seeding devices and methods for utilization of the devices are described. The devices include a rolling needle support that carries a plurality of channeled needles thereon. Upon rolling the support over the surface of a scaffold, the needles penetrate the scaffold surface and deliver cells to the interior of the scaffold. The devices can deliver cells to a scaffold at a high density with high cellular retention and survival.

Abstract: Determining inkjet printer pen turn-on voltages is disclosed. An inkjet printer has a number of pens, and a number of sets of nozzles in each pen. Each set of nozzles of a pen is fired at each of a number of voltages, to obtain a voltage-value curve for each set of nozzles. A nozzle turn-on voltage for each set of nozzles is determined based on a maximum slope of its voltage-value curve. The turn-on voltage for each pen is determined based on the nozzle turn-on voltages of the voltage-value curves for its sets of nozzles.

Abstract: A computerized aid to creativity and problem solving to help speed up the creative process using an interactive database comprised of two major parts, or functions. The first part is a database of several thousand questions for clarifying the task, modifying ideas, and evaluating goals, ideas, and outcomes. The second part is a database or more than 60,000 words and phrases expressing the shared concepts of a particular culture, namely American, and more than 650,000 idea associations-to which any number of a user's personal, idiosyncratic connections can be added. The invention utilizes principles of association, memory retrieval, and analogical reasoning. Whether taken literally or as figures of speech, the two databases prompt a user to make his or her own connections by reminding the user of thoughts, feelings, experiences, facts, and images stored so deeply in memory that they normally cannot be retrieved at will.
