Abstract: A tube array and a method for additively manufacturing the tube array are provided. The tube array includes an outer wall formed by a plurality of curved segments and defining a primary flow passage. A plurality of divider walls are positioned within the primary flow passage to divide the primary flow passage into a plurality of tubes, each of the plurality of tubes being defined at least in part by one of the plurality of curved segments and two of the plurality of divider walls. Integrally formed inlet and outlet manifolds provide fluid communication between the tube array and an array inlet and outlet.

Abstract: A device to prepare an infusion, such as a brewed beverage, by moderating and manipulating the extraction rate of a particulate base during an infusion, a related method to prepare such an infusion, and a resultant product of such a method.

Abstract: An interpreter based augmentive communications system ("ACS") and method for enabling handicapped individuals to generate sentences and also to control external devices. The ACS may employ auditory or visual feedback to present category and word choices to the user. With a single switch the user may select categories and words from these choices which then are stored in an input buffer to permit the construction of sentences. Alternatively, the user may select choices which permit the control of external devices such as a wheelchair by manipulating the single switch. The microprocessor controlled ACS system incorporates a simplified programming language and interpreter to permit nonprogrammers to construct user programs that are tailored to the particular needs of the individual user. In additon, as the user gains proficiency in using the ACS, the user program can be easily revised to permit more efficient and sophisticated communications.
