摘要:
A method and a device for ascertaining and mapping data representing the optical imaging properties of an eye of a person, in which n different test images are displayed individually in succession on an electronically controllable monitor unit, are seen by the person from a settable viewing angle and at a settable distance, and are identified by means of an input comprising: a) ascertaining a characteristic viewing angle value at a given distance, at which a first probability for correct identification of the test images is achieved, b) ascertaining a characteristic distance value while maintaining the ascertained characteristic viewing angle value, at which a second probability for correct identification is achieved which is greater than the first probability, c) repeating steps a) and b).

A selection in a browser can be mapped back to a corresponding location range in one or more source files that generated the selection. A selection in a source file can be mapped to the corresponding location range in the browser's DOM. The selection in the browser can be mapped to a location range in a block list generated from the DOM. The location range in the DOM's block list can be mapped to a corresponding location range in a block list generated from the fetched file received from a web server. The location range in the fetched file's block list can be mapped to a particular location in the particular source file responsible for generating the selection in the browser. The selection in the browser and the source file can be displayed concurrently, the source file scrolled to the location range corresponding to the selection in the browser.

An element in a fetched file (a file received from the web server in response to an HTTP request) can be mapped to the source code that generated it and vice versa. When code is compiled at the web server, calls can be executed that emit HTML that includes metadata that maps a snippet of code back to a particular source file and to a particular location in the source file. The HTML can include injected symbols that specify that the information from a particular start position for a particular character length in the HTML comes from a particular start position to a particular end position in the source file.

A selection in a browser in an integrated development environment can be mapped back to the original document that was fetched from a web server by uniquely identifying elements in the original document. A DOM can be created from the original document where the DOM retains the unique identifiers associated with the elements. Block lists for the original document and the DOM can be created. A differencing algorithm can be run on the two block lists. A selection in a browser can be mapped to a location in the DOM block list and the location in the DOM block list can be mapped to the original document.
摘要:
A circuit breaker has at least one housing having at least one opening, and at least one pair of contacts located in the housing, the contacts of the pair of contacts being mobile in relation to each other for opening and closing an electric circuit. An open-pore metal foam (20) is interposed between at least one of the pairs of contacts and at least one housing opening (11), the metal foam being electrically insulated from the current-carrying elements of the circuit breaker (1). An open-pore metal foam (20), produced of a zinc base alloy or aluminum base alloy, can be used as a cooling structure for the dissipation of heat from switching gases that are produced by an electric switching process.

An electric arc extinction chamber system, especially for low-voltage circuit breakers of very high nominal current intensities, wherein parallel electric arc extinction chamber inserts are provided in a housing extending over the entire width of a pole-face arc. The housing of the chamber is sub-divided by a partition wall or several partition walls which are embodied as components of the housing. The compartments thus formed receive arc splitter cartridges.

A connector rail includes a full profile which is provided with first bearing surfaces and second bearing surfaces which are used to provide support in the window opening of the rear wall of the housing. The second bearing surfaces are provided with projections for securing continuous current conductors which are aligned in a parallel manner and which are, for instance in the case of low voltage circuit breakers, embodied as male contacts for fixed contacts. Respectively corresponding projections are provided in order to secure the flexible cables to the moveable switching contacts or to secure the fixed switching contacts.
摘要:
A structural component made of hard material for a wristwatch, characterised in that it includes a hole fitted with an inner threading which is integral with said component, said threading being directly obtained by injection and thus without removing any material of said component for example by machining.
摘要:
The wristband with links (2, 3, 4) includes a plurality of bars (5) acting as means for linking and articulating the links with each other and means for holding said bars in said links. Each bar is held axially by at least one of its ends (13) on to a link (2) by means of a collared sleeve (6) designed and arranged to abut against holding means (7, 8) carried both by the bar and the link.
摘要:
The invention pertains to a housing assembly for electrical or electronic built-in components, with an outer housing feature two lateral walls, a rear wall, a front cover, a roof and a floor, and an inner housing that is lodged with spacing from the wall parts of the outer housing. In a visually appropriate design favorable conditions for ambient weather influences can be provided simultaneously, in that the roof of the outer housing is constructed such that it is curved convexly upward and drops off toward the lateral walls, such that the front cover is curved convexly toward the front, and that the transition between the roof and the front cover is formed of an obliquity that drops off toward the front.
