Abstract: A field effect transistor device constructed in accordance with the present invention includes a channel of semiconductive material such as silicon having at least one row of pores extending therethrough. Internal pn junctions are fabricated within the porous region, such that the inside of each pore is coated with a layer of opposite conductivity type semiconductive material. When voltage is applied to the internal pn-junctions, the space charge around the pores widens or contracts, depending upon the direction of the bias, thereby permitting the modulation of current flow through the channel.

Abstract: The display bracket assembly is essentially a two part apparatus having an insert plate member that is positioned within a vertical slot and a support member that extends into the vertical slot and couples to the insert plate member. The interconnection between the support member and the insert plate member retains the support member in a set position on the slatwall structure. In a preferred embodiment, latching elements and a locking projection extend from the support member. The latching elements are sized and oriented so that the latching elements will only pass into the vertical slot when the support member is held at a predetermined first orientation. After the latching elements are advanced into the vertical slot, the support member can be rotated into a second orientation from the first orientation.

Abstract: A VIBER vibrating mechanism is coupled to a cannula or needle and operates to provide flexural vibrations to move the needle and to enable detection of the position of a needle within a body of interest by a color ultrasound imaging system. The VIBER mechanism exhibits multiple modes of oscillation when energized. The VIBER mechanism is excited to exhibit predetermined oscillations at a given frequency in the X plane, a predetermined oscillation at another frequency in the Y plane and still another frequency of oscillation in the Z plane. In this manner, the VIBER mechanism device exhibits motion in all three planes, which motion is detectable by a conventional color ultrasound imaging system. The frequency of oscillation is a function of the entire system, namely the VIBER mechanism, the needle or cannula which is attached to the VIBER mechanism and the tissue. The resonant frequency is preferred as it provides larger vibrational amplitudes.

Abstract: There is disclosed a cathode-ray tube which employs an electron gun assembly of the laminar flow (LF) type. The beam emanating from the LF electron gun assembly is directed through a three-electrode einzel lens assembly where the center electrode of the einzel lens assembly is subjected to a modulation voltage. Positioned after the einzel lens assembly are magnetic deflection circuits which include a horizontal and vertical coil enabling the beam to deflect in the horizontal and vertical directions and which circuits are positioned internally within the CRT. A convergence assembly is also built within the neck of the CRT. Thus, the CRT provides the advantages of the laminar flow gun while enabling modulation of the electron beam to provide an extremely small spot size to enable the CRT to operate with small spot size and to provide more efficient deflection at higher modulation rates.

Abstract: The present invention is a tilt switch that opens or closes an electrical circuit in accordance with the angle of inclination of the switch. The present invention switch includes a housing that defines a hollow cavity. A first sphere, having a highly conductive circumferential surface, is positioned within the hollow cavity. As the switch is inclined, the first sphere rolls to one end of the housing where the sphere contacts an electrical connector. The first sphere electrically interconnects the electrical connector to the housing on which the sphere rests, thereby completing an electrical connection between the electrical connector and the conductive material of the housing. At least one second sphere is also positioned within the housing. The second sphere is sized in relation to the hollow cavity so that the first sphere cannot pass by the second sphere within the cavity. As the switch is inclined, the first sphere rolls against the electrical connector, closing the switch.

Abstract: A lancet device uses a planar blade that implements an incision in the skin of a patient using a slicing action. There is a blade support arm pivotably secured within a hollow housing. The pivot connection between the blade support arm and the housing is formed by a pivot pin which extends from the housing and is positioned in a slot receptacle formed on the blade support arm. The pivot pin is free to reciprocally move within the slot receptacle as the blade support arm pivot about the pivot pin. The rotation of the blade support arm about the pivot pin is implemented by a bias spring. The path traversed by the blade support arm as it pivots is controlled by a groove located on the interior surface of the housing which engages a projection that extends from the blade support arm. As such, when the support arm pivots from a first position to a second position, the projection on the blade support arm traverses the groove in the housing.

Abstract: An apparatus and method for performing a coagulation time test on a sample of blood wherein the blood is deposited in a fluid reservoir and disposable cuvette. Within the cuvette is formed a capillary conduit have at least one restricted region. The cuvette is inserted into a testing machine which engages the cuvette and draws blood from the fluid reservoir into the capillary conduit. The blood is then caused to reciprocally move within the capillary conduit whereby the blood is forced to traverse the restricted region. The testing machine measures the time required each time the blood is caused to traverse the restricted region. When a measured time is a predetermined percentage longer than an immediately preceding time, coagulation is considered to have occurred and the overall coagulation time is displayed to the operator.
