摘要： An electronic keyboard instrument is provided and methods of playing and assembling the same. The instrument comprises a controller for enabling activation of electronic signals having audible, visible, amplifiable, recordable and/or like characteristics, and a power source for operating the controller. A first keyboard is provided having a first selected length and being oriented in a first direction such that (i) audible notes of music from at least one internal sound module and/or at least one external sound module, (ii) recordable data to be enhanced or modified by an external sequencer or program controlled apparatus, (iii) photoelectric signals, and (iv) processes or mechanisms, triggered or controlled by external signals or data, for controlling machines, video playback or lighting, and/or the like may be generated and/or activated using a first hand of one or more users. A second keyboard with a second selected length is generally coextensive with and oriented generally opposite to the first such that (i) audible notes of music from at least one internal sound module and/or at least one external sound module, (ii) recordable data to be enhanced or modified by an external sequencer or program controlled apparatus, (iii) photoelectric signals, and (iv) processes or mechanisms, triggered or controlled by external signals or data, for controlling machines, video playback or lighting, and/or the like may be generated and/or activated using a second hand of the one or more users. In addition, an interface connects the controller to at least one external device having sound module, and/or sequencing and signal enhancement functions. A plurality of peripheral devices operatively connected thereto permit interactive control and manipulation of the signals. Finally, a wearable support is mounted to the instrument for suspending the first and second keyboards from the user's body during instrument operation. Alternatively, the instrument is suspended by a support structure in a generally horizontal fashion for simultaneous operation by multiple users.

摘要： A support and a method for assembling micro-components to binding sites on the support are provided. The support has a pattern of electrical conductors adapted to conduct electrical energy between binding sites. In accordance with the method, an electrical signal is passed through at least one conductive path including at least one of the conductors so that heat is generated by a portion of each conductive path proximate to the binding sites, a first fluid is applied to the support that is adapted to increase in viscosity when heated, and, a carrier fluid having first micro-components adapted to engage the binding sites is applied to the support. Wherein the heat from the at least one conductive path increases the viscosity of the first fluid in areas proximate to the selected binding sites so as to inhibit first micro-components from engaging the binding sites.

摘要： A droplet generator is provided that is particularly adapted for generating micro droplets of ink on demand in an inkjet printhead having a plurality of nozzles. The droplet generator includes a droplet separator formed from the combination of a droplet assistor and a droplet initiator. The droplet assistor is coupled to ink in each of the nozzles and functions to lower the amount of energy necessary for an ink droplet to form and separate from an ink meniscus extending across the nozzle outlet. The droplet assistor may be, for example, a heater or surfactant supply mechanism for lowering the surface tension of the ink meniscus. Alternatively, the droplet assistor may be a mechanical oscillator such as a piezoelectric transducer that generates oscillations in the ink sufficient to periodically form convex ink meniscus across the nozzle outlets, but insufficient to cause ink droplets to separate from the outlets. The droplet initiator cooperates with the droplet assistor and selectively causes an ink droplet to form and separate from the ink meniscus. The droplet initiator may be, for example, a thermally-actuated paddle. The droplet separator increases the speed and accuracy of ink micro droplets expelled from the printhead nozzles.

摘要： The present invention resides in a self-cleaning printer with a print head having an orifice plate defining an ink jet orifice, a cleaning orifice and a drain orifice. The orifice plate further defines an outer surface between the orifices. A source of pressurized cleaning fluid is connected to the cleaning orifice and a fluid return is connected to the drain orifice for storing used cleaning fluid. A cleaning surface is disposed adjacent to and separate from the outer surface to define a capillary fluid flow path from the cleaning orifice across the ink jet orifice and to the drain orifice. During cleaning, the source of pressurized cleaning fluid discharges a flow of a cleaning fluid into the capillary fluid flow path and pressurized cleaning fluid from the capillary flow path passes through the drain orifice and into the fluid return.

摘要： A micro-actuator includes a body of deformable elastomer material having opposed first and second surfaces spaced apart by a predetermined at-rest dimension. A charge mechanism is coupled to one of the opposed surfaces for applying an electrical charge across the body in a first direction. The charge is spatially varied in a second direction substantially normal to the first direction so as to create spatially varied mechanical forces across the body such that body exhibits spatially varied growth in the first direction. A rigid member is associated with the second opposed surface of the body so as to move in the first direction in response to growth of the body. The charge mechanism may include a grille electrode connectable to an electrical potential source. An electrically conductive flexible layer is provided on the second surface between the second surface and the rigid member, and is connectable to the electrical potential source so as to induce a force between the flexible layer and the grille electrode upon application of an electrical field. A stationary rigid substrate is provided between the first surface and the grille electrode to establish a rigid mechanical boundary at the first surface.
