Patent EP-0394932-A2 (EP)
Inventor: WINSCHUH ERICH
IPC: G01N25/72
Filed: 1990-04-23
Abstract: Situated inside a portable measuring head (A) is the laser light source (FL), preferably a directly modulated, diode-pumped neodymium/YAG laser. Its laser beam (f1) is directed without optical waveguides using a scanner device (5) and a dual optical system (6) onto the scanning zone of the material sample (B) to be inspected. The irradiated measuring track is, for example, meander-shaped with beam deflection in the x and y direction. The dual optical system (6) transmits the IR light signals (- DELTA  f3) emitted by the sample (B). These are focussed on an IR detector (8) via the scanner device (5) and a coupling mirror (4b) in the form of a dichroic mirror which reflects the laser beams (f1) in one direction and acts as a transparent window in relation to the IR light signals (- DELTA  f3) in the other direction, and via an IR optical system (7). The IR detector (8) converts the IR light signals (- DELTA  f3) into corresponding electrical signals. The measuring head (A) is connected via a flexible electrical connecting cable to an electronic image generating unit from which the electrical signals for controlling the laser (FL) and guiding the beam originate. 
<??>The invention also relates to a number of advantageous uses of the method and also to a device for carrying it out.

Abstract: A method of recording a digital data signal, such as an audio PCM signal, onto a recording medium in the lon­gitudinal direction thereof, together with an apparatus which is suitable for this recording method. Even-­numbered words and odd-numbered words in a digital data signal are recorded on a first track group and a second track group, respectively, which are separated from each other in the widthwise direction of a recording medium, to prevent a series of words becoming error words because of, for example, a flaw in the recording medium in the longitudinal direction thereof. The data format is chang­ed at the input and output of a recording encoder to enable an error correction code and a recording circuit to be used in common for digital tape recorders which have different numbers of tracks, e.g., n tracks and 2n tracks. When an error correction code is recorded in such a manner that one word in the digital data signal is divided into a plurality of symbols which are formed into an error correction code, a plurality of symbols of the same word are recorded at a position at which error correlation is strong, making effective use of the error correction capacity of the error correction code.

Abstract: A SECAM chroma signal is filtered and supplied to a single axis demodulator, which demodulates first and second chroma signal components modulated with two carriers having frequencies above and below a center frequency, as well as an identification signal for discriminating the transmission order of the first and second chroma signals. An identification signal detector, supplied with the demodulated identification signal, discriminates the transmission order of the first and second chroma signals in accordance with a positive or negative polarity. A rectifier rectifies the discrimination signal, and generates an average output of the discrimination signal. A flip-flop circuit generates a switching signal representing periods of the first and second chroma signal components on the basis of the discrimination signal. An amplifier adjusts the level of the switching signal in accordance with the average output, and generates an off-set control signal. An adder adds the off-set control signal and the demodulated first and second color signals so that the first and second color signals have the same reference levels.

Abstract: Text Cells are provided which define the boundaries into which text data can be formatted for presentation. The definition of Text Cells is controlled by two data stream commands which are the Define Text Cell (DTC), and Open Text Cell (OTC). The DTC command specifies the parameters associated with a Text Cell Chain. This command includes a set of global parameters to be applied to each Text Cell to be presented following the issuance of this command. The OTC command causes an individual Text Cell to be established. That is, the area associated with the Text Cell is opened, the presentation parameters for the cell are set, and the text information which follows this current Open Text Cell, but precedes a subsequent Open Text Cell, is processed into this area. Text Cells can have presentation attributes which are independent of the attributes of the text presented therein, and which govern presentation characteristics not usually associated with text presentation. Additionally, multiple text cells can be specified on a presentation page, and the relationship of individual Text Cells to other Text Cells on the presentation page can be described.

Abstract: A distributed data processing system and method in which locks on a file are supported by a data structure that resides on either a client machine or on the file's server. When only a single client's processes are locking a file, the data structure can reside on that client. Whenever a plurality of client machines attempt to place locks on a file, the data structure is moved to the server; this forces the clients locking the file to communicate with the server when performing lock operations. When a client requests a lock from the server that cannot be granted because of an existing blocking lock, the client is informed that it should put the requesting process asleep awaiting a retry notification. When there is a change in the locks on the file that might allow such a client's now sleeping process to acquire the lock, the server sends a retry notice to the client. This awakens the sleeping process at the client, and the process then reattempts the lock operation by sending a message to the server.

Abstract: A high pressure proximity sensor for high pressure environments uses a balanced bridge variable inductance magnetic core structure to detect the presence of a external ferrous object by a change in inductance. The sensor magnetic flux path is defined by the sensor's specific geometry which includes core windings (20, 22) on the core and sensor housing (2). The core includes centre post (26) of a nonmagnetic material to transfer stress from a housing sensor face to the core's symmetric axis to cancel the effect of an external pressure induced stress on the sensor. The centre post (26) is encircled by an elastomer barrier (28) between the housing sensor face and an adjacent end of the internal core to prevent migration of an internal potting compound between the core end and the sensor face. This structure provides satisfactory sensor operation in environments imposing shock and vibration on the sensor as well as high external pressures.
