Abstract: Device and related method for determining the surface area of a wound. The device comprises a transparent sheet having a series of perforations defining first and second sections of the sheet which allow the first and second sections to be separated from one another along the perforations. The transparent sheet is folded along the perforations so that the two sections overlap each other, and the sections are substantially free of adhesive material. The second section includes indicia thereon which allow a user to determine the surface area of a wound after the outline of the wound or opening is traced thereon. Upon use, the device is placed over the wound or opening, with the first section toward the wound or opening, and the outline of the wound or opening is traced onto the second section. The second section containing the marked outline of the wound, which was isolated or shielded from contact with the wound, is then separated from the first section along the perforations, allowing the second section to be immediately handled by a person, i.e., without subjecting the second section to cleaning or sterilization.

Abstract: An optical fiber protected from degradation caused by corrosion from environmental fluids. The optical fiber (200) includes a core-cladding assembly (202,204) surrounded with a thin quasi metal oxide film (206) (preferably ∼10 nm in depth). Over time, particularly under the influence of the elevated temperatures, the initially deposited reagents of the thin film (206) oxidize or hydrolyze, removing the organic components, and bonding a quasi metal oxide film (206) on the surface of the cladding (204). The resulting film significantly retards corrosion by blocking the environmental fluids from reacting with flaws in the cladding surface of the fiber, thus improving the mechanical performance and reliability of the optical fiber. In addition, the thin film protects the fiber against incidental abrasions. Alternatively, the quasi metal oxide reagents are deposited into a protective polymer layer of the fiber or a filling compound of a fiber cable, rather than directly onto the cladding surface, whereby the same protective effect is achieved when the reagents diffuse through the polymer layer or filling compound to the core-cladding surface.

Abstract: The present invention is a method for decreasing rotational latency in systems which include a data retrieval element (12) and a rotating medium (10). The method requires that the rotating medium be divided into a plurality of discrete angular regions (20A-20J, 40A-40J). For each discrete angular region, a number of cylinders that may be traversed by the data retrieval element during a single revolution of the medium is identified. A rotational latency is assigned to each discrete angular region based on a current location of the retrieval element. A command queue array is searched for a command that addresses a location within a range of cylinders determined by the number of cylinders in the discrete angular region having the smallest rotational latency. Finally, the command addressing a location in the range of cylinders in the selected discrete angular region of the medium is executed.

Abstract: A substrate is provided with vias communicating with surface contacts or bumps. Joining material paste is forced through holes in a screen onto an area array of the contacts on the substrate then the screen is biased against the substrate as the paste is heated and cooled to transfer the joining material onto the contacts. Alternately, joining material paste is forced into the screen and then a substrate is placed onto the screen with an area array of bump contacts of the substrate in contact with the solder paste, and then the paste is heated and cooled to transfer the material onto the bumps. The joining material may be a solder paste, conductive adhesive paste, or transient liquid bond paste. The substrate may be a semiconductor chip substrate, flexible or rigid organic substrate, or a metal substrate coated to form a dielectric surface. Also, the substrate may be a computer chip, chip carrier substrate or a circuit board substrate. The process may be used to produce flip chips, ball grid array modules, column grid array modules, circuit boards, and attachment structures of the preceding components including information handling systems.

Abstract: Each of N current summation type digital-to-analog (D/A) converters (23) of a liquid crystal display driver generates an analog signal (OUT) which provides pixel video information. In an error sampling interval of the D/A converter, the output signal of the D/A converter developed when the data to be converted is at full scale is compared in a comparator (131) with a reference voltage (VREF). An error signal (ERROR) is sampled and is used for varying a control voltage (VCP2) developed in a capacitor. The control voltage controls the current sources (120) of the D/A converter in a current mirror manner. The reference voltage is coupled in common to each of the comparators of the D/A converters. In this way, matching among the D/A converters and the accuracy of each are enhanced.

Abstract: A liquid discharging method for discharging liquid by displacing a movable member by means of a bubble created on the bubble generating area, which the free end of the movable member faces, comprises the step of promoting the movement of the free end of the movable member by means for promoting the displacement of the free end thereof. With the adoption of this method, the pressure of the bubble that acts upon the free end of the movable member enables the movable member to form an appropriate displacing configuration to lead the pressure exerted at the time of foaming and the development of the bubble in the discharging direction efficiently. At the same time, the displacement of the movable member is performed smoothly, thus contributing to enhancing the durability of the movable member.

Abstract: In an air conditioning system (10) for controlling the temperature of a vehicle passenger
compartment, a valve (107) is disposed in a fluid passageway for controlling an amount of the
engine coolant flowing toward the heat exchanger (103). A sensor device (16) senses an air
temperature for the air flow through the heat exchanger and generates an electrical sensor
signal indicative thereof. A temperature selector selects a target temperature of the air
flow through the heat exchanger (103) and generates an electrical set signal indicative thereof.
A control circuit (18) controls opening of the valve (107) by integrating a feed-back control and a
feed-forward control based on the electrical sensor signal and the electrical set signal.
Therefore, the air conditioning system (10) is adapted for improving control response
characteristics without influences from disturbances and ensures improved control to
provide stable control with rapid response to achieve a target temperature or a
modification to the set temperature inside of the automobile compartment, or both.

Abstract: A sliding side door assembly (10) for use in a well bore having a side
bore. The assembly (10) comprises a housing (12) having a generally tubular shape
defining a central axis (X). A side port (28) is formed in the housing (12), and a ball
seat (30) is positioned in the housing (12) adjacent the side port (28). A door
subassembly (14) is operatively engaged with the housing (12) adjacent the side port
(28) and includes a translating sleeve (34) positioned within the housing (12) and a
ball sealing member (36) adapted to engage the ball seat (30) of the housing (12). A
ball port (40) is formed through the ball sealing member (36). A cooperatively
engaged helical track (42) and follower member (44) are provided for translating a
driving movement along the central axis (X) through the translating sleeve (34) to a
rotational movement of the ball sealing member (36) about the central axis (X).
Driving movements acting on the door subassembly (14) can be provided by a
standard shifting tool (46). Thus, a first driving movement acting on the door
subassembly (14) in a first axial direction along the central axis (X) causes the
translating sleeve (34) to rotate the ball sealing member (36) such that the ball port
(40) moves into overlapping alignment with the side port (28), thereby opening the
side port (28). Similarly, a second driving movement acting on the door subassembly
(14) in a second axial direction along the central axis (X) causes the translating sleeve
(34) to rotate the ball sealing member (36) such that the ball port (40) moves out of
overlapping alignment with the side port (28), thereby closing the side port (28).
