Title: Telecommunication system and a main station for use in such a system
Inventor: GRINSVEN PETRUS AUGUSTINUS VAN
IPC: H04J3/00
Filed: 1994-03-11
Abstract: ABSTRACT: "A telecommunication system and a main station for use in such a system"     Telecommunication systems such as PON-FITL-Systems are known with a TDMA frame structure comprising a main station and a number of substations. The known systems can comprise means for coarse ranging and means for fine ranging. The present invention proposes improved Pseudo Noise Sequence based coarse ranging means. According to the present invention coarse ranging is done at a fixed position (CR) within the upstream multiframe (up) reserved for ranging, preferably for fine ranging. By applying a low power Pseudo Noise Sequence (rseq) for coarse ranging and sampling the range at the side of the main station only within the fine ranging window (CR), the position of which is known to the main station, a more accurate coarseranging is achieved. The present invention is based upon the insight that within the fine ranging window normally no data are present, and thus the signal-to-interference ratio is an order of magnitude better than in the other part of the frame.

Abstract: A memory controller which makes maximum use of any processor pipelining and runs a large number of cycles concurrently. The memory controller can utilize different speed memory devices and run each memory device at its desired optimal speed. The functions are performed by a plurality of simple, interdependent state machines, each responsible for one small portion of the overall operation. As each state machine reaches has completed its function, it notifies a related state machine that it can now proceed and proceeds to wait for its next start or proceed indication. The next state machine operates in a similar fashion. The state machines responsible for the earlier portions of a cycle have started their tasks on the next cycle before the state machines responsible for the later portions of the cycle have completed their tasks. The memory controller is logically organized as three main blocks, a front end block, a memory block and a host block, each being responsible for interactions with its related bus and components and interacting with the various other blocks for handshaking. The memory controller utilizes differing speed memory devices, such as 60 ns and 80 ns, on an individual basis, with each memory device operating at its full designed rate. The speed of the memory is stored for each 128 kbyte block of memory and used when the memory cycle is occurring to redirect a state machine, accomplishing a timing change of the memory devices. <IMAGE>

Title: Immunological method of analysis
Inventor: GALLATI HARALD
IPC: G01N33/543
Filed: 1993-07-30
Abstract: In a diagnostic procedure for the detection or quantitative determination of antibodies in biological fluids by means of an immunological reaction, in which the sought antibodies are incubated with the corresponding antigen, one portion of which antigen is bound to a water-insoluble carrier, and the other portion of which is provided with a label, after the separation of the phases measuring the extent of the label either in the liquid or in the solid phase, it is possible for components of the analytical sample to bind a labelled antigen to a water-insoluble carrier in an unspecific manner, thus producing incorrect positive results. In order to obtain valid results, the same reaction is conducted but incubation takes place in the presence of an excess of non-bound and non-labelled antigen and, after separation of the phases, the measured extent of the marking is also taken into consideration in the qualitative evaluation or the quantitative analysis of the antibodies. The procedure is particularly suitable for the analysis of human antibodies to rabbit globulin, the antigen being a rabbit globulin.

IPC: G06F3/046
Filed: 1992-10-19
Abstract: ABSTRACT OF THE DISCLOSURE      A cordless digitizer system is disclosed which comprises a digitizer tablet and a cordless pointing device which cooperate to provide to the tablet information relating not only to the position of the pointing device relative to the tablet, but also relative to the status of any switches on the pointing device. The pointing device generates and radiates to the tablet first and second signals of different frequencies.  The first and second signals are radiated from the pointing device at a third frequency which contains information of the status of the switch.  For example, one of the signals may be radiated relatively continuously of both of the signals may be alternatingly radiated at the third frequency in dependence upon the status of the switches.  The first and second signals induce corresponding signals in the tablet which are processed to provide respective signals at the third frequency.  These signals are then processed to obtain the status of the pointing device switches.  Switch status information can also be binary encoded as a particular sequence of alternations of the first and second signals.

Title: Collector for trolley bus
Inventor: SIVERS CARL
IPC: B60L5/10
Filed: 1992-10-06
Abstract: The invention describes a traffic system especially with vehicles driven by electricity as trolley busses but also and at the same time for instance trucks and private cars driven by electricity.  The collector (4) is always perpendicular to the length of the vehicle (3) also when the collector is out from the sides. It is pressed in the direction towards the wire pair (1) just so much to keep the mean pressure of the wires on the contact shoes (22) about the same in both directions. This decreases or removes the risk for derailing. The driver can quickly and automatically without alighting return still derailed collectors. Should a vehicle stop with the collector on a spot icy or else lacking voltage, the collector is pulled forward a distance to regain voltage. In switches the collector is pushed to the correct line by the driver, the wheel or automatically directed by an outside signal. Should arcs develop the current is automatically cut electronically. A  simple computer industrial type can co-ordinate the values measured on the vehicle and outside signals, if any.

Filed: 1994-11-14
Abstract: An imaging device comprising a Focal Plane Array (FPA) image sensor having a grid formed of individual detector elements, arranged in an array of columns and rows, and a mask with a checkerboard pattern of opaque and transparent areas, the mask being located in front of and adjacent to the FPA onto which an image of a scene can be focused by an optical system.          The imaging device is provided with means for displacing the mask and FPA with respect to each other in a number of micro-steps that extend in the same direction as that in which a column of the grid extends and a means for displacing the mask and FPA with respect to each other in a number of micro-steps that extend in the same direction as that in which a row of the grid extends.  The micro-steps in any one direction are of equal lengths which are each a fraction of the length of a detector element.  Opaque areas of the mask will then progressively cover equal areas of detector elements in discrete steps for each micro-step movement in one direction at the same time as transparent areas of the mask progressively uncover equal areas of other detector elements for each discrete step.  Outputs from the detector elements provide signals for sample slices of the scene for each micro-step and the device has means for reconstructing an image of the scene from those signals.  This arrangement allows an enhanced image to be obtained for the scene from the sample slices compared to the image which is obtainable directly from a FPA image sensor or previous types of microscanning arrangements.
