Abstract: A red-emitting strontium-calcium sulfide phosphor doped with europium and a halide. These phosphors are made by combining their insoluble sulfates, adding europium as an activator, firing in hydrogen sulfide to form the corresponding sulfides, adding a halide co-activator and firing in nitrogen. The resulting phosphors can be used with various electroluminescent devices to produce colored or white light.

Abstract: A lightweight bicycle fork which includes a crown, a stem and a pair of opposed tubular struts. The stem is fitted into a bore in a central position of the crown and extends above the top surface of the crown. The pair of opposed struts are disposed to extend downwardly from the bottom surface of the crown. The struts are attached to the crown by being disposed within opposed bores within the crown and secured within the crown by threadable end caps. To prevent the rotation of the struts within the crown, longitudinal ribs can be disposed within the external surface of the struts which mate with matching grooves within the internal surface of the bores. The struts are reenforced with an internal web to strengthen the struts with respect to axial and lateral forces. The bicycle fork is made from lightweight materials such as aluminum.

Abstract: In an instrumentation system, the functionality of an I/O interface which controls an instrument is extended with an I/O interface extension library. The extension library operates to receive a function call and determines whether the function call is supported by the underlying I/O interface. If the function call is supported by the underlying I/O interface, the function call is passed on to the I/O interface for processing. If the function call is not supported by the underlying I/O interface, the function call is decoded into a sequence of standard I/O primitives that are supported by the underlying I/O interface, which are then sent on to the I/O interface for processing. In one embodiment, reduced overall latency time is achieved by packaging multiple sequential functions into a package and sending the package over an I/O bus to the instrument I/O controller as a single unit rather than sending each sequential function using separate bus instructions.

Abstract: A three port FIFO buffer circuit uses off the shelf static RAM and dedicated shallow, e.g. 16 word, FIFOs in a multi-level caching scheme. The circuit results in multiple, reconfigurable, deep (e.g. up to 32k word) FIFO buffers. The preferred embodiment of the invention provides a buffer that comprises a bank of 32k word RAM, six dual port 16-word FIFOs, and associated sequencing logic. The sequencing logic includes RAM address registers/counter associated with each of the six FIFOs, and manages the movement of data into and out of the RAM.

Abstract: A bidirectional asynchronous open collector buffer. The buffer employs set delays and control logic to prevent latch up of the buffer when the low signal is applied to one of the ports of the buffer. Additionally, the buffer employs reset delays in conjunction with the control logic for suppressing oscillation of the buffer when one of the ports of the buffer is released from the applied low signal.

Abstract: A ground return scheme is provided for multiple high speed digital signals that are capacitively coupled between networks, where the networks are connected to different ground planes (i.e. they are isolated) on a common circuit board. A first embodiment of the invention provides a low impedance ground path for each signal crossing the isolation boundary. The ground path is achieved by placing a ground return capacitor proximate to the signal coupled capacitor to substantially minimize the loop area of the total current path. This arrangement substantially minimizes the self inductance of each signal current path and the mutual inductance, i.e. coupling, between signal paths. The arrangement also has the benefit of reducing self-induced voltage drops in each ground return path, thereby reducing crosstalk between the signals, reducing ground bounce (resulting in faster settling times), and also reducing common-mode voltage induced between the grounding systems.

Abstract: Methods and associated apparatus for using a dual-boot capable programmable device and for updating programmed information in such a dual-boot capable programmable device. The apparatus of the present invention includes a primary boot memory device, a secondary boot memory device, and means for selecting between the two memory devices for purposes of "booting" the dual-boot mode device. In particular, a reset switch of the apparatus of the present invention resets devices in the dual-boot capable programmable device and is coupled to a selection device. The selection device multiplexes signals from the two boot memory devices onto the corresponding bus signals of the dual-boot capable programmable device. When a "long" reset switch activation is sensed, the selection device selects a first of the two boot memory devices for coupling to the programmable device. A "short" activation of the reset switch selects the other boot memory device.

Abstract: The invention is a mounting bracket for securing a portable hand holdable appliance to a window extending vertically from a window sill. In detail, the bracket includes a plate having first and second side and top, bottom and side edges, and additionally, an attachment device to mount the appliance. A pair of suction cups are mounted on the first side of the plate horizontally spaced from each other in proximity to the top thereof. The bottom portion of the plate extends from the plane of the plate at an acute angle outwardly from the first side and terminates in a pointed edge. Thus the bracket can be secured to the surface by wedging the pointed edge between the window and sill and rotated thereabout so that the suction cups engage the window.

Abstract: An improved method is disclosed of imparting a tint or color to a soft, hydrogel contact lens by uniformly dispersing a dye throughout the lens. The dye is composed of a water-soluble compound essentially free of ethylenic unsaturation. A homogeneous solution of the dye in a hydrophilic monomer is prepared, the solution is subjected to polymerization conditions to yield a hydrophilic polymer from which the lens is formed, and the dye dispersed within the polymer is bonded to the polymer by contact with aqueous base prior to final hydration.The finished lens does not require soaking in an aqueous solution of the dye to impart the desired tint or color to the lens. Additionally, the dye uniformly dispersed throughout the lens according to the improved method does not leach out of the lens or migrate within the lens.
