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 lateral flow device, and related systems and methods is disclosed. A method of building a lateral flow immunoassay device comprises dispensing, via a fluid ejection device, a flow-inducing substance to form a flow membrane, and dispensing, via the fluid ejection device, a measured volume of biosubstances from an array of biosubstances to form a sample module, a tagging module, a reaction module, and a waste module on the membrane.

Abstract: A method for making a patient monitor includes providing an electronic device operatively connected to the monitor. The device is configured to measure predetermined signals from a user and to generate therefrom a substantially unique signature specific to the user. The method further includes storing the signature in the electronic device. The electronic device is adapted to compare newly acquired signatures to the substantially unique signature, and to recognize at least one difference from the substantially unique signature. Recognition of a difference in the signatures signifies a new user, whereupon the electronic device acquires new predetermined signals and generates therefrom a new substantially unique signature specific to the new user.

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 microtray for handling biosubstances comprises a fluid holding structure and a fluid ejection structure. The fluid holding structure includes an array of wells with each well configured to contain at least one biosubstance. The fluid ejection structure is in communication with the fluid holding structure and configured to dispense the at least one biosubstance onto a target media.

Abstract: A method of making microcapsules including activating a fluid ejector at a frequency greater than 10 kilohertz where each activation of the fluid ejector generates essentially a drop, and the fluid ejector is fluidically coupled to a first fluid including a core component. The method further includes ejecting the drop of the first fluid into a second fluid, the drop having a volume. In addition, the method includes generating a microcapsule, that includes the core component, in the second fluid for each drop of the first fluid ejected.

Abstract: A method and device for delivering a quantity of at least one material to a selected single cell in a manner that permits impingement of material with the cell. The material travels at a suitable trajectory and velocity and is ejected from an electronically controllable fluid device.

Abstract: Sheets of base substrate (e.g., transparency film, glass, or other suitable growth material) are coated with an array of spots of the same or different growth media and/or nutrients. Coating may be accomplished using an ink-jet printer, which deposits droplets of a growth medium and/or one or more nutrients on the substrate.

Abstract: A power switch control unit for controlling the operation of a controlled electric device connected to the unit includes a housing having a timing mechanism therein; a power cord having a plug on one end thereof, for connection to a power supply, and having the housing on the other end thereof, for supplying electrical power to the unit and to a connected-electric device controlled by the power switch control unit, and a receptacle for receiving a power cord from an electric device to be controlled by the power switch control unit; control buttons, including: an on/off button for connecting a controlled electric device to the power supply; a timer activation button for activating the timing mechanism, wherein, when the timing mechanism is activated, it connects a controlled electric device to the power supply for a predetermined amount of time in a timed cycle, and then disconnects the connected-electric device from the power supply; and a clear timer button for terminating the predetermined amount of time, a

Abstract: Embodiments of an ophthalmic apparatus are disclosed for administering fluids to the eye. In one disclosed embodiment, the ophthalmic apparatus includes an eye-positioning device for assisting a subject in positioning an eye in a desired position for administering the fluid and a fluid applicator for dispensing the fluid into the eye when the eye is in the desired position.

Abstract: A rotating shaft motor or cartridge incorporates an o-ring which surrounds the rotating shaft and is borne on a carrier. As supported on the carrier, the o-ring does not normally block the bearing passages which would prevent the smooth distribution of oil throughout the motor. However, the carrier and o-ring combination are designed to allow the o-ring to be forced into an opening between the shaft and sleeve for completely sealing the remaining portion of the bearing during filling. The rotating shaft includes a central reservoir, having one or more grooves or passages communicating with the hydrodynamic bearing surfaces and ending in a septum or rubber plug which is inserted in an opening in the shaft.

Abstract: A spindle motor operates dynamically in one of two modes for a disc drive. During power-up, the disc drive electronics are configured to operate the motor in a line-to-line configuration, thus assuring generation of adequate torque. An operating condition circuit senses when the motor has attained substantially the desired running velocity .omega., after which, the drive electronics are dynamically reconfigured to operate the spindle motor in a line-to-neutral mode. A power interruption circuit senses when the source power supply V.sub.cc voltage level is too low or turned off, thereafter initiating a reconfiguration back to line-to-line mode, wherein the highest voltage pair of motor windings are electrically held across the source power supply V.sub.cc lines. Simultaneously, a switching circuit electrically connects the V.sub.cc lines across the transducer positioning voice coil motor in the disc drive, thereby delivering current from the spindle motor to the voice coil.
