Title: Method for the prevention of eye damage when using high-power lasers
Inventor: BORN GUNTHARD
IPC: G01S7/48
Filed: 1994-07-12
Abstract: To prevent eye damage when using a high power laser in a spectral range transparent to the eye lens, e.g. for destroying military targets, a warning beam (I2) is generated in the visible or near-infrared range just before the main high power beam (I1) is generated. The warning beam causes the eyelids to close by reflex action, and eye damage by the main beam is therefore avoided. The main and warning beams may be generated from a single Nd-yag device, the warning beam being provided by doubling the operating frequency of the device. <IMAGE>

Title: Structural truss
Inventor: THOMAS MERVYN HARVEY
IPC: E04C3/16
Filed: 1994-08-15
Abstract: A structural truss, eg to provide support in building, exhibition, display lighting, decorative and other structures, comprises an elongate framework at opposite ends of which are connectors 3, 3' of a common forked form spaced limbs 11, 12 of which have registering holes 14 for a retaining pin or bolt 15 and are disposed to be vertically spaced apart in a normal orientation of the truss in use. The arrangement of the connectors 3, 3' relieves the retaining pins or bolts 15 of at least a substantial portion of the load of, and on, the truss when it is in use. In the illustrated embodiment the connectors enable the truss to be inverted from one orientation to another for use, and two of the trusses to be connected together end to end. Securing in different orientations is facilitated by having the limbs 11, 12 of each connector offset relative to an anchorage 9 of the connector to the framework, and having the limbs of a connector at one end of the framework offset in the opposite direction to the limbs of a corresponding connector at the other end of the framework. <IMAGE>

Title: A method and a system to transfer digital signals between a digital signal processor and peripheral circuits connected to it
Inventor: ESALA HANNU TAPANI
IPC: H04Q11/04
Filed: 1993-04-23
Abstract: The description relates to a method and a system to transfer digital signals between a digital signal processor or a DSP circuit (3) and peripheral circuits (1, 2) connected to it, the signals being transferred between the peripheral circuits and the DSP circuit relatively often compared to the operational speed of the DSP circuit. Then there is a difficulty in that other activities of the DSP circuit repeatedly must be interrupted in order to transmit and receive signals, which i.a. makes it difficult to write the program. According to the invention this problem is obviated in that the digital signals are transferred from a peripheral circuit (1) to the DSP circuit (3) via a switching matrix (5), whereby a certain number of signals are assembled in the switching matrix and transmitted as a respective cluster to the DSP circuit or from the DSP circuit, and correspondingly between the assembled signals there remains a longer continuous period for signal processing in the DSP circuit. A typical example is an A/D-converter, which transmits digital signals in time slots on a time-division bus to the DSP circuit. With the aid of the switching matrix several signal samples can be grouped into sequential time slots and correspondingly the intervals between the groups add to form a continuous processing period. <IMAGE>

Title: Modelling an underground reservoir
Inventor: GUERILLOT DOMINIQUE
IPC: G01V1/30
Filed: 1996-05-07
Abstract: A model simulating the behaviour of an underground reservoir (eg of oil) is defined on the basis of initially known geological information and available data. It enables production forecasts to be made using parameters representative of the initial data. The method essentially consists in defining one or several possible scenarios of developments during production by creating, for each of these scenarios, fictitious new production data corresponding to hypotheses about the future states of the reservoir. For each scenario considered, it is checked whether the available parameters of the simulation model can be adjusted, given the constraints of the initial geological model so that the simulation model reproduces both the measured production data and the added data. The method may be used to quantify the uncertainties regarding production forecasts by finding the min/max extremes of future production values.

Patent GB-971359-A (GB)
IPC: H04L25/497
Abstract: 971,359. Telegraphy. LENKURT ELECTRIC CO. Inc. June 11, 1963 [July 2, 1962; Dec. 17, 1962; Jan. 30, 1963], No. 23174/63. Heading H4P. In a limited bandwidth data transmission system binary data is converted to a 3-level signal, whereby the data may be sent faster than would be possible in binary form. The signal is such that adjacent pulses are in adjacent levels or in the same level, and is reconverted at the receiver. Transmitting arrangements.-Binary signals, e.g. 13, Fig. 4, are fed to gate 11 which, whenever a clock pulse and a mark are present, triggers unit 12. The output of this is therefore as waveform 14. This waveform is fed to an adder both direct and via a 1 bit delay. The resultant waveform is filtered by the transmission equipment, waveform 16, and sent by A.M., F.M., or P.M. line or radio path to the receiver. The waveform 16 is regarded as a 3-level signal, the levels being as indicated. Receiving arrangements.-In one embodiment, Fig. 5, the received signal is fed to slicing circuits which provide waveforms 21A, 21B, Fig. 4, representing the upper and lower levels of the signal. These waveforms are fed to gate 22 as shown, together with clock pulses. Whenever gate 22 pulses, unit 24 provides a mark pulse. A second gate 23, fed as shown, causes unit 22 to provide a space. The output of unit 22 is the re-converted waveform 13. A second embodiment, Fig. 6 (not shown), converts the received signal 16 to waveform 14 before reconstituting the binary data 13. In a further embodiment the transmitted waveform 16<SP>1</SP>, Fig. 9, is passed through a fullwave rectifier to give waveform 18<SP>1</SP>. This wave form, after squaring, is the reconstituted data. If the waveform has jitter it is stabilized by the circuit of Fig. 11 (not shown). Error detection.-It is inherent in the conver sion of the binary data that when a pulse in level 1 or 2 is followed by an even number of adjacent middle level pulses the next pulse will also be in the level 1 or 3, respectively, whereas if it is followed by an odd number of middle level pulses the next pulse will be in level 3 or 1, respectively. Thus an error detecting arrangement can be constructed, as in Fig. 13 (not shown), which will predict the pulse to be received after one or more middle level pulses. There may be included with the detector a counter which is periodically reset and, for example, causes repetition of a block of data if too many errors are counted. Alternative arrangement.-The binary signals are fed direct to the delay-and-adder circuit, Fig. 1A (not shown), the transmitted signal then being as waveform 42, Fig. 8. The data is reconstituted by the circuitry of Fig. 7 (not shown).

IPC: C23C14/04
Filed: 1997-10-23
Abstract: A method of vacuum depositing a layer or layers on a substrate includes controlling thickness distribution of the layer or layers over the substrate by a threedimensional mask located between the substrate and a vapour source. A plurality of coduits, 52S, extends, 52L, through the mask from one side to the other for allowing passage of gaseous coating material from a source to the substrate. The throughput of the conduits for gaseous coating and thus the amount of gaseous material transmitted by the conduits is inversely related to the ratio of length to diameter of the conduits. The conduit dimensions are graded progressively over the mask to provide corresponding gradation of a deposited layer.

Title: Oscillator and method for controlling the same
Inventor: TSUMURA SOICHI
IPC: H03J7/08
Filed: 1997-11-28
Abstract: A digital temperature compensation oscillator by which an AFC operation to a received signal cannot be disturbed by a temperature compensation operation. A digital temperature compensation oscillator comprises a temperature sensor 1 an address creating section 2, a ROM 3a, latch 4, and a voltage-controlled crystal oscillator 9. The temperature sensor produces an output signal varied according to ambient temperatures. The address creating section converts an output from the temperature sensor into a signal and then creates it as a ROM (read-only memory) address. The ROM stores a control voltage to compensate a frequency variation due to ambient temperatures of a voltage-controlled crystal oscillator. The latch 4 holds or passes data output from the ROM according to an external control signal 400. The D/A converter produces a control voltage for the voltage-controlled crystal oscillator according to the latch 4. The voltage controlled crystal oscillator is fine adjusted based on two control voltages including the output signal from the D/A converter and an external analog AFC signal 700. The external AFC signal may also be latched (fig 2).

Title: Temperature control circuit for a thermal inkjet printhead
Inventor: CORRIGAN GEORGE H
IPC: B41J2/05
Filed: 1998-09-23
Abstract: The circuit includes a die (11, Fig.1) with a temperature sensor 44 thereon, which produces a sensor voltage output 46, proportional to a sensed temperature of the die. A digital counter 20 generates a digital word which passes via a digital output 32 to a digital to analogue converter 34. The converter produces an analogue output voltage 40, proportional to the voltage on an analogue reference input line 36 and the value of the digital word received. A comparator 50 has a first input 46 connected to the sensor voltage output and a second input 40 connected to the converter output voltage. The comparator generates an equivalency signal on an output line 52 when the converter output voltage exceeds the sensor output voltage. The circuit may also include a temperature control section 16 which compares the digital word with a preselected temperature threshold value 66,70 to determine if the die temperature is within a selected range. The temperature being changed in response to a determination that the temperature is outside the range. Thus, the die temperature is increased if it is too low, and if the temperature is too high, the print operation is slowed or disabled.
