Abstract: A printhead includes a chamber layer and at least two orifice layers. A first orifice layer is disposed on the chamber layer, and a second orifice layer is disposed on the first orifice layer. The second orifice layer has at least one counterbore formed therein. A first nozzle is formed through both orifice layers and produces droplets of a first drop weight. A second nozzle is formed through the first orifice layer, coincident with the counterbore, and produces droplets of a second drop weight that is different than the first drop weight. In one embodiment, the printhead is used in a stand-alone fluid-dispensing device.

Abstract: An inkjet material dispenser system includes a printhead member. According to one exemplary embodiment, the printhead member includes at least one drop ejector including an insulating stack layer and a top orifice surface defining an orifice, wherein a ratio of a diameter of the orifice to a height of the insulating stack layer (O/L ratio) is at least 1.0.

Abstract: A dispenser for building a lateral flow immunoassay device comprises a fluid supply assembly and a jetting assembly. The fluid supply assembly comprises an antibody component including a plurality of reservoirs to supply at least one of member of a group comprising a species array of at least one species-specific antibody material, an anti-species array of at least one first anti-species antibody material, and a label-antibody array of at least one of a tag material and a second anti-species antibody material. The jetting assembly is in communication with the fluid supply assembly to enable dispensing the materials of the species array, the anti-species array, and the label-antibody array from the supply assembly onto a substrate.

Abstract: A method of forming a biological sensor on a predetermined area of a substrate. The method includes dispensing a plurality of layers on the predetermined area of the substrate. Each of the plurality of layers is formed of a substantially different fluid having a substantially different function. The dispensing of the layers is accomplished by a drop generating member.

Abstract: A system for a computing device of one embodiment of the invention is disclosed that includes an image-capturing mechanism and a controller. The image-capturing mechanism is capable of capturing images. Each image includes at least one corner of a display communicatively coupled to the computing device. The controller is to determine at least one of positioning and relative movement for a graphical-user interface element displayed on the display, based on the images captured by the image-capturing mechanism.

Abstract: A display device including a light engine configured to project an image onto a display surface, an image sensor configured to capture a presentation image larger than the projected image, and a processor, coupled to the image sensor, that is configured to modify the projected image based on the captured image.

Abstract: A portable sensor device for obtaining physiological information, including cardiopulmonary information, from a human or animal subject. The device includes a housing having a lumen and a respiratory port in fluid communication with the lumen. The lumen can be divided into plural airflow tubes. Spirometric data can be integrated with non-spirometric cardiopulmonary data collected by the device. Additionally, the sensor device can be operably coupled to a bioactive composition delivery device. Methods for using the sensor device and methods for making the sensor device also are disclosed.
