Abstract: A system for delivering material onto a substrate. The system includes a jetting system having a reservoir containing the material and the reservoir includes a nozzle through which the material is expelled from the reservoir. An arcuate section is positioned between the reservoir and the nozzle. The material is configured to travel from the reservoir, through the arcuate section, and through the nozzle. The system also includes a means for applying pressure on the material contained in the reservoir, wherein the material is expelled from the reservoir through application of pressure by the means for applying pressure to thereby create a column of the material from the nozzle. A means for producing pressure modulations is located proximate the nozzle and is configured to substantially regulate formation of droplets from the column of the material. In addition, the system includes a charging ring configured to induce an electrical charge to selective ones of the droplets as they pass through the charging ring.

Abstract: A storage device including many field emitters in close proximity to a storage medium, and a micromover, all in a partial vacuum. Each field emitter can generate an electron beam current. The storage medium has many storage areas on it, with each field emitter responsible for a number of storage areas. Also, each storage area can be in a number of different states to represent the information stored in that area. In storing information to the storage device, the power density of an electron beam current is increased to change the state of the storage area bombarded by the electron beam current. In reading information from the device, the power density of the electron beam current is reduced to generate a signal current from the storage area bombarded by the electron beam current. During reading, the power density is selected to be low enough so that no writing occurs. The magnitude of the signal current depends on the states of the storage area.

Abstract: A multipurpose body exerciser includes an I-shaped bottom block mated with a vertical main frame and a support frame for mounting of a seat and a back cushion on the main frame. The exerciser further includes two elongated foot-pedals disposed at both sides of the vertical main frame, each respectively suspended by a steel cord hung on a pulley block to provide the foot-pedals for training of the legs. Two vertical rocker rods are provided on opposing sides of the vertical main frame for training of the arms. The foot-pedals and the rocker rods are adjustable by associated hydraulic cylinders, to provide a predetermined tension for providing the best performance appropriate to a user's condition. The whole structure may be divided into three independent portions for convenient transportation or packaging to minimize space requirements.
