Abstract:
An abrasive element comprises a body of crystalline abrasive material. The body has an array of cutting elements formed of crystalline abrasive material which projects from a surface of the body. The shape, size and form of the projections is controlled in the production process. The body may be a natural or synthetic crystal. The body may be a film formed by deposition. The body may be diamond or cubic boron nitride. The body may be monocrystalline or polycrystalline. The projections may be aligned along a crystallographic plane or planes.
Abstract:
A method and system for mapping color gamuts based on one-one and onto mapping function in order to create an invertible transform is disclosed. A hue leaf associated with at least two arbitrary color gamuts can be defined utilizing a vector math function and a most saturated point with respect to each hue leaves can be determined. A safe area relative to an intersection point can be estimated by approximating the most saturated point in both hue leaves. An upper hull and a lower hull associated with the hue leaves can be continuously sub-divided with an equal number of sections by constructing one or more vectors. An appropriate section for computing a vector relationship in the color gamut can be determined in order to map the color gamuts based on the continuous, one-one and onto function thereby creating an invertible transformation.
Abstract:
A NFC enabled device to couple inductively to the H field of an RF signal and a regulator to regulate a voltage derived from an RF signal inductively coupled to the inductive coupler. The regulator has at least one voltage controlled impedance having a switch on voltage. A regulator controller provides a control voltage to each voltage controlled impedance such as that the control voltage is not less than the switch on voltage of the voltage controlled impedance.
Abstract:
A programmable logic device (“PLD”) is augmented with programmable clock data recover (“CDR”) circuitry to allow the PLD to communicate via any of a large number of CDR signaling protocols. The CDR circuitry may be integrated with the PLD, or it may be wholly or partly on a separate integrated circuit. The circuitry may be capable of CDR input, CDR output, or both. The CDR capability may be provided in combination with other non-CDR signaling capability such as non-CDR low voltage differential signaling (“LVDS”). The circuitry may be part of a larger system.
Abstract:
A near field RF communicator has an antenna circuit (102) to couple with the H field of an RF magnetic field and a power supply deriver (301) to derive a rectified auxiliary power supply from the received magnetic field. Rectification may be performed using an actively switched rectifier (502) having a passive mode of operation. A sub regulation system (506) is provided to regulate the auxiliary power supply to inhibit the possibility of temporally varying power requirements of the near field RF communicator or its host causing an apparent load modulation of a signal that is transmitted or received by the communicator.
Abstract:
Generating a hardware description for a programmable hardware element based on a graphical program including multiple physical domains. A graphical program may be received which includes a first portion of a first physical domain for simulating a first portion of a physical system. The graphical program may include a second portion of a second physical domain for simulating a second portion of the physical system. A hardware description may be generated based on the graphical program. The hardware description may describe a hardware implementation of the graphical program. The hardware description may be configured to configure a programmable hardware element to simulate the physical system.
Abstract:
A heavy duty torsion bar assembly, particularly an anti-roll bar assembly for a rail vehicle, includes a lever which is mounted on the bar by an oil injection taper fit, the cooperating surfaces having a drainage groove and being formed to a tolerance of IT7 or better, wherein the final assembled position is determined by a pre-defined axial displacement of the lever from an initial position defined by manual engagement of the two parts.

Abstract:
A system and method for configuring a device to perform a function, where the device includes a programmable hardware element and one or more fixed hardware resources. A program is stored which represents the function. A hardware configuration program is generated based on the program, specifying a configuration for the programmable hardware element that implements the function, and usage of the fixed hardware resources by the programmable hardware element in performing the function. A deployment program deploys the hardware configuration program onto the programmable hardware element, where, after deployment, the device is operable to perform the function, where the programmable hardware element directly performs a first portion of the function, and the programmable hardware element invokes the fixed hardware resources to perform a second portion of the function. An optional measurement module couples to the device and performs signal conditioning and/or conversion logic on an acquired signal for the device.
Abstract:
A computer-implemented system and method for generating a hardware implementation of graphical code. The method may operate to configure an instrument to perform measurement functions, wherein the instrument includes a programmable hardware element. The method comprises first creating a graphical program, wherein the graphical program may implement a measurement function. A portion of the graphical program may be converted into a hardware implementation on a programmable hardware element, and a portion may optionally be compiled into machine code for execution by a CPU. The programmable hardware element is thus configured utilizing a hardware description and implements a hardware implementation of at least a portion of the graphical program.
