Abstract: Systems, devices, and methods for neurostimulation via vestibular stimulation are described. One example is a device for administering thermal stimulation to an ear canal of a subject. The device may include an earpiece configured to be at least partially insertable into the ear canal of the subject; a thermoelectric device thermally coupled to the earpiece and configured to heat and/or cool the earpiece to thereby heat and/or cool the ear canal of the subject; and a controller configured to administer a selected treatment plan including administering a caloric vestibular stimulation (CVS) stimulus to the ear canal of the subject in a condition-treatment effective amount during a first treatment interval. The treatment plan may be effective to produce a durable improvement in at least one symptom of the condition for a time of at least 1 week following cessation of the administering.

Abstract: Methods and systems for inserting and replacing swaged probe pins in a lower die portion of a head having an array of micro-holes for receiving the probe pins are disclosed. The methods and systems include the following: swaged probe pins including substantially cylindrical ends and a swaged center portion; and an assembly aid film including an array of slotted holes, each of the slotted holes including a substantially round portion for receiving the substantially cylindrical ends of the swaged probe pins and slot portions for receiving the swaged center portion of the swaged probe pins. The array of slotted holes is configured to properly align the swaged probe pins with the array of micro-holes.

Abstract: A method and apparatus for detecting and classifying an object, including a human intruder. The apparatus includes one or more passive thermal radiation sensors that generate a plurality of signals responsive to thermal radiation. A calculation circuit compares the plurality of signals to a threshold condition and outputs an alarm signal when the threshold condition is met, indicating the presence of the object. The method includes detecting thermal radiation from an object at a first and second wavelength and generating a first and second responsive signal. The signals are compared to a threshold condition that indicates whether the object is an intruder.

Abstract: An ink supply system for an impulse ink jet apparatus includes a hand peristaltic device for priming. Ink is supplied by a removable container by gravity feed through a valve mechanism.

Abstract: A dense array of ink jets is achieved by a fanning-in of chambers to a linear array of orifices. The ends of the chambers remote from the orifices have actuation locations which are coupled to elongated transducers having axes of elongation which are parallel to the axes of ejection of droplets from the orifices.

Abstract: A process and apparatus (invention) permitting the distribution of micro or submicro liter or gram (exceptionally small) quantities of liquids and powders, (hereafter materials) in patterns and quantities that are especially well-suited for ophthalmologic patient self-application of drugs to his own eye(s) with substantially no overdose. The invention is thus also highly beneficial in those many topical drug applications where overdoses should be avoided. This is particularly applicable for the eye, where overdoses can have many deleterious medical consequences. Use of the invention permits exceptionally small doses of ophthalmologic drugs. Moreover, it also permits the repeatability of the quantity size of the materials chosen for delivery. In the case of drugs, particularly opthomologic drugs, this means that the invention permits the repeated multiple distribution of the same chosen drug/carrier quantity resulting in a uniform repeatable dosage.

Abstract: An impulse fluid jet apparatus having pulse generating circuitry for an impulse jet. The circuitry generates driving a longer pulse exciting the resonant frequency of the jet and a shorter pulse for exciting a higher harmonic frequency of the jet. The longer pulse changes the state of energization of the transducer in the jet to eject a droplet of fluid and the shorter pulse changes the state of energization so as to break off the tail of the droplet.

Abstract: An ink supply system for an impulse ink jet apparatus includes a hand held peristaltic device for priming. Ink is supplied by a removable container by gravity feed through a valve mechanism.

Abstract: Device and method for delivering small microliter volumes of liquid preparations to the eye or other body part utilizing a gas stream to induce a controlled, preselected volume of liquid into the gas stream and to deliver the liquid in the form of small droplets to the desired site.

Abstract: Ink jet chambers of an array of ink jet devices extend laterally outwardly from a linear array of elongated transducers. This configuration creates two sets of linear arrayed orifices utilizing a single linear array of transducers so as to provide large field, high density printing for use in, for example, printing bar codes.

Abstract: An ink supply apparatus comprises a container for storing ink jet ink having an opening for releasing ink from the container and a valve member mounted in the opening in the container and spring means coupled to the valve member for biasing the valve member so as to prevent the flow of ink from the container when the ink supply is not mounted on a supply base.

Abstract: Impulse ink jet apparatus has a plurality of side-by-side chambers extending along a line that is slanted with respect to a direction of scanning relative to a recording medium. Each of the chambers includes a plurality of orifices that are arranged along a line extending substantially transverse to the scanning direction and a transducer for ejecting a plurality of droplets from the orifices of each chamber. The orifices are formed upon an orifice plate such that the distance between the centers of adjacent orifices associated with a single chamber are separated by a predetermined distance greater than the center distance required for drop placement on the recording medium.

Abstract: An impulse ink jet apparatus provides bar coding using one or more ink jet chambers having a plurality of orifices in each chamber. A transducer is coupled to each chamber for ejecting droplets from each of the plurality of orifices in the chamber in response to the state of energization of the transducer.

Abstract: Brightness control apparatus for a video signal processing system wherein the video signal is pre-conditioned to establish a prescribed reference level during image blanking intervals. The prescribed reference level is afterwards further modified by adding a black-going pulse component to the video signal during the blanking intervals. The magnitude of the added pulse component is adjusted in accordance with the setting of an adjustable brightness control to control the brightness of images displayed by an image display device included in the system. Controlled video signals are AC coupled to an intensity control electrode of the display device by a DC restoration circuit which responds to the magnitude of the added blanking interval pulse component, for establishing the DC bias of intensity control electrode and thereby image brightness.
