Abstract: With this call-registering keyboard and display device, calls for desired floors can be input without a registering key having to be pressed after a correct input or without a correction key having to be pressed after an incorrect input. Here, a call input is only possible when a proximity switch (28) connected to the keyboard (20) is activated. Upon deactivation of the proximity switch (28), a delay circuit (31) causes the call to be automatically registered. An incorrectly input call is automatically cancelled by means of a second control circuit (61), in which case a second display element (60) in the form of a double question mark lights up at the same time. A third display element arranged in the same display field and signalling the selected lift as well as a fourth and fifth display element signalling the position of the selected lift relative to the actuated keyboard (20) are connected to a group control device via further control circuits. During the call assignment the third and the relevant fourth or fifth display elements are activated, which then light up together with a first display element signalling the selected floor and already activated during the call input.

Abstract: A double acting hydraulic drilling jar 1 includes a mandrel 2 arranged in a housing 3 for sliding longitudinal movement. A hammer 69 is positioned on the mandrel 2 and interacts with anvil surfaces 64, 66 in the housing 3 to deliver both upward and downward jarring forces to a drill string. A hydraulic valve arrangement permits the storage of large amounts of static force before releasing the hammer 69 to strike the anvil surfaces with great force. The hydraulic valve arrangement includes a tripping valve 95 positioned to be actuated by a first pair of engaging surfaces in response to downward movement of the mandrel 2 in the housing 3 and a second pair of engaging surfaces in response to upward movement of the mandrel 2 in the housing 3. Thus, independent control over the upward and downward jarring action is achieved.

Abstract: A system for remote management includes central management, planning and rationalization of the upkeep of elevator installations. The system comprises a modularly constructed remote management system, which makes possible the management centrally, the inspection regionally and the monitoring of decentralized processes locally of elevator installations. The management exchange is connected by modem and telephone network with the regional exchanges and has access to all relevant data. The regional exchange permits an inspection of all processes of several buildings. Direct speech connections with all the peripheral devices are by means or remote alarms from the regional exchange. For each building, a communications module manages the data traffic between the regional exchange and the processes to be inspected in the building. The process data is detected by a peripheral module, which is capable of diagnosis, and is processed further into relevant operational, fault and alarm reports with the aid of heuristic operating means. The peripheral module reports diagnostic data by way of the common building bus to the communications module, which transmits the data to the regional exchange by means of automatic telephone dialing.

Abstract: A dimming switch terminal unit for monitoring a dimming-up switch and dimming-down switch and a dimming control terminal unit for performing dimming control of an associated light load are connected to a central control unit through a two-wire signal line.  The central control unit accesses each of the terminal   units   to   perform   time-divisional   multiplex transmission of monitor data and control data therebetween.

Inventor: ORSINO FRANCESCO
IPC: G06F7/544
Filed: 1990-12-28
Granted: 1998-05-12
Abstract: Method and apparatus for processing on-line operands A, B and C to produce the arithmetic expression S = (A x B) + C.  In general, the apparatus comprises an input processing unit, an on-line multiplication unit, and an on-line serial addition unit.  The input processing unit is for sequentially introducing the digits of operands A, B and C into the apparatus, where each digit is represented in a redundant binary number format.  The multiplication means multiplies the sequence of digits of the operands A and B to produce the n-th product digit Pn of the product P = A x B, with the most significant digit Po being computed first.  The on-line addition unit adds the n-th product digit to the n-th digit of on-line operand C, so as to produce the n-th digit Sn of the arithmetic expression S = (A x B) + C, with the most significant digit So being produced first.  In one embodiment, the input processing unit comprises a selective conversion subunit for selectively converting the digits of operands A, B and C sequentially entering the computational device, so that each digit is represented in a redundant number format.  In such an embodiment, the redundant binary number format is characterized by signed digit numbers, and the selective conversion subunit comprises a binary-to-signed digit converter.  Also, the input processing unit preferably includes a word-length control subunit for restraining the word length of the operands and intermediate words to a predetermined limit. In yet another embodiment, the apparatus hereof includes an arithmetic performance testing system for determining whether or not the arithmetic processor is functioning properly.

IPC: C07K17/08
Filed: 1991-06-04
Granted: 2003-04-22
Abstract: The current invention is a method, kit and reagents for detecting cobalamins in a sample. The method involves introducing into the sample a first conjugate of a latex or latex-like solid phase linked to affinity purified intrinsic factor with a first linking group at least three angstroms long. The first conjugate and the bound cobalamins in the sample are then exposed to a second conjugate of a cobalamin linked to a detectable enzyme to produce second conjugate bound to first conjugate and unbound second conjugate. The enzyme activity associated either with the solid phase first conjugate or the unbound second conjugate is then detected. By linking affinity purified intrinsic factor to a latex or latex-like solid phase with a first linking group at least three angstroms long, an enzyme assay can be performed which detects levels of cobalamins in patient samples within or below normal ranges found in such samples.

Title: Digital generation of synthetic aperture radar images
Inventor: MOREIRA ALBERT
IPC: G01S13/90
Filed: 1991-11-22
Granted: 1995-02-07
Abstract: In a method for digital generation of synthetic aperture radar (SAR) images obtained by means of a coherent imaging system a signal compression in the azimuth and/or range direction is carried out with high resolution by means of a subaperture configuration. A stepwise linear approximation of a quadratic phase characteristic is performed with regard to a reference function and frequency overlapping of the subapertures is effected for optimizing the approximation of the phase characteristic. For the formation and synthesis of the subapertures complex multiplications are carried out, the signal of each subaperture thereby being shifted in the frequency. The individual subapertures are integrated twice by means of the moving average method for reducing the side lobes of the low resolution impulse response and after a time shift for equalizing the relative positioning of the subapertures and after the complex multiplications for the frequency shift the results obtained in the individual subapertures are coherently summated.
