According to some aspects, a hybrid optic is provided. The hybrid optic comprises a capillary optic for receiving x-rays from an x-ray source at an entrance portion of the capillary optic and for providing x-rays at an exit portion of the capillary optic, and a grazing incidence multi-shell optic (GIMSO) coupled, at an entrance portion of the GIMSO, to the exit portion of the capillary optic to receive x-rays emerging from the exit portion of the capillary optic, the GIMSO including an exit portion for providing x-rays.

An intelligent shelving system integrates touch sensors, displays, lighting, and other components into shelves. Touch sensors can be used as limit switches to control shelf motion, to monitor items borne on shelves, to detect spills, and to control lighting and other devices and functions. Displays can provide information relating to objects stored in the shelving system and the operation and status of the shelving system.

A method of managing inventory may include using a handheld scanning device to locate one or more inventory items on a retail display. The method may further include scanning the identification symbols of inventory items on a retail display to determine the type of the scanned item. An associated apparatus may include a communication interface to receive information from a remote database and to send information to a remote server. The received information may include predetermined information about proper locations for individual inventory items on the retail display, thereby reducing the need to manually determine the proper locations of multiple inventory items, which may be, for example, greeting cards on a retail store display.

The equation operating system is an improved data and command entry format together with a compatible operation system for use with electronic data processing apparatuses, most particularly with scientific calculators which provide an alphanumeric display of entered equations. This invention provides a different set of commands and displayed characters for performing exponentiation. An up arrow together with a down arrow serve to define the expression of the exponent. The numeric data stored in a numeric display register upon implementation of the exponentiation is raised to the power of the expression between the up arrow and the down arrow. This invention also includes an integral power exponentiation command which enables easy entry of single digit positive integral exponents, thereby eliminating the need for a completing command.
摘要:
A data processing apparatus employs a single key stroke for defining a complex number entry and for designating a particular complex number calculation mode. Entry of a complex number follows the following format: entry of the first part of the complex number, entry of a complex number mode designation command, and entry of the second part of the complex number. Entry of the complex number mode designation command designates the numeric data to be assigned the first part and the second part of a complex number and also causes the data processing apparatus to enter a corresponding complex number computation mode. Thereafter, upon entry of at least some of the normal operational commands of the data processing apparatus, these operational commands are performed upon the previously entered complex numbers in accordance with the mathematical laws of complex number arithmetic. The data processing apparatus preferably generates an indication of when a complex number computation mode has been set. Display of the two parts of a complex number is facilitated by an exchange operational command which exchanges the first and second parts of the complex number so that the other part of the complex number may be displayed. In a further preferred embodiment, complex numbers may be stored and recalled from pairs of user accessible memories in a manner similar to the normal operations on real numbers.

A data processing apparatus having a plurality of preprogrammed functional operations and at least one user accessible memory includes a generalized input sequence for combining functional operations with data storage in one of the user accessible memories. In the case where a number of user accessible memories is provided, memory entry is enabled by a store input followed by an input designating the memory while a memory recall operation is enabled by a recall input followed by a memory designation input. The algebraic memory operation and entry sequence requires entry of the store input, the desired operation input and the memory designation input. If a unary operation is selected, the selected operation is performed on the data stored in the output indicator memory or alternately on the data stored in the designated memory and the result is stored in the designated memory. If a binary operation is selected, the selected operation is performed using the data stored in the designated memory as the first operand and the data stored in the output indicator memory as the second operand, and the result is stored in the designated memory. With modifications this entry sequence can also be used to perform combined operations and memory entry for an apparatus having only one user accessible memory.

A chemical composition and method for repairing a thermal barrier coating on a component designed for use in a hostile thermal environment, such as turbine, combustor and augmentor components of a gas turbine engine. The method repairs a thermal barrier coating on a component that has suffered localized damage to the thermal barrier coating. After cleaning the surface area of the component exposed by the localized spallation, a paste-like mixture of a ceramic composition comprising ceramic powders and nano-sized ceramic materials in a binder is applied to the surface area of the component, and is optionally smoothed using mechanical means. The composition is then allowed to dry and cure to form a dried coating having polymeric characteristics. Upon subsequent heating, the dried coating reacts to produce a glassy ceramic repair coating. Due to the thixotropic properties of the coating composition upon application to a component, the repair method can be performed in-situ while the component remains installed in its operating environment.
摘要:
A layer of transparent conductive material is disposed on a surface of a substrate. Further layers of conductive material are deposited on the layer of transparent conductive material or on an opposite surface of the substrate. The layers are selectively etched to yield a layout of pads for mounting electrical components and conductive traces forming an electrical circuit.
