  • Patent number: 6377905
    Abstract: The present invention relates to methods and to arrangements for monitoring an object which emits a rotating or oscillating beam whose angular velocity is unknown. The time points at which the beam passes a predetermined number of measuring positions are determined. An angular velocity start value is generated and a predetermined number of object position determinations (at least two independent determinations) are made on the basis of the determined time points, the measuring positions and the start value. It is determined whether or not the position determinations can be considered to be sufficiently in agreement with one another. When agreement is considered sufficient, the start value is accepted as an approximate value, this value approximating the angular velocity of the beam with an acceptable degree of accuracy. If the position determinations are not found to be sufficiently in agreement, the start value is modified and new position determinations are made.

  • Patent number: 6342851
    Abstract: The duty cycle of a pulse train from a pulse radar antenna is increased by dividing the antenna aperture into sub-apertures (1-5), generating separate pulse trains from said sub-apertures (1-5), and time shifting the separate pulse trains between themselves to produce a resulting pulse train having shorter pulse spacing or wider pulses.

  • Patent number: 6333733
    Abstract: A position-sensing unit for determining a relative position in one or more dimensions of two units. One or more position-sensing units can be used in a multidimensional pointer, such as a control lever, for controlling a position in up to six dimensions of, e.g., and object on a display. A position-sensing unit comprises a radiation source, a detector and a screen element arranged in the beam path for partial screening off of radiation. The radiation source and the detector comprise individual or separate fields for emitting or detecting radiation, in which case it is possible to distinguish radiation associated with one field from radiation associated with other fields. The determination of a position is carried out based on a comparison between the intensities of non-screened-off radiation associated with the different fields.

  • Patent number: 6222487
    Abstract: A method and a system for determining an altitude of an object of interest, for example, an airplane that transmits electromagnetic radiation in the form of radar signals. A number of sub-units that can detect the radar signals are spread out in an area, preferably in a large geographical area, where the radar signals of the airplane/object it is possible to detect. The sub-units communicate to the information center when they are able to detect the radar signals. The information center determines the altitude of the airplane based on the airplanes line of sight, i.e., its radar horizon, and thus which sub-units can detect the radar signals.

  • Patent number: 6111537
    Abstract: Method for reducing false target echo indications in a pulse Doppler radar having at least two different pulse repetition frequencies during the period in which the main beam of the radar illuminates a target. A target which is detected gives rise to a number of primary detections in each PRF. The method includes use of at least one variable criterion and a final criterion, which are both of the M/N type. The factor M in the variable criterion is initially greater than the factor M in the final criterion. The method also includes the feature that primary detections which are all to be found in the same range gate in a number of PRF's, which number is equal to the factor M in the variable criterion, are approved as targets in this range gate.

  • Patent number: 5990833
    Abstract: System for determining the position of radar transmitters where the system includes at least one information center with associated cells and means of communication between the information center and the cells with a restricted transfer rate utilising existing infrastructure in the country, such as for example a national telephone network and also mobile telephone networks and their base stations. Each cell includes at least one sensor in order to be able to detect radar signals. Leading edges of pulses in the radar signals are detected and time-marked after which they are sorted according to PRI (Pulse Repetition Interval). The time of arrival for the first pulse in a pulse train is calculated and data reduced by modulo calculation to a value that as a maximum is the propagation time difference for pulses between two cells in a pair of cells/sensors that are used together for calculating the bearing.

  • Patent number: 5966091
    Abstract: A procedure and a device transmit information in a pulse radar device simultaneously with the ordinary radar function of the pulse radar device. The radar device includes a control unit, a radar transmitter and an antenna. The control unit controls the radar transmitter to generate radar pulses in pulse groups that are transmitted via the antenna. The pulse groups for the ordinary radar function are information coded by position coding by the control unit of the information that is to be transmitted. The pulse groups are position coded by transmitting radar pulses with time displacements relative to their nominal radar pulse positions. Pulses are received and information decoded to thereby recreate, in the form of an information copy, information that has been positions coded and transmitted by a radar device.

  • Patent number: 5941417
    Abstract: A system to be utilized at a dairy in the distribution of a pumpable food product from a storage tank to a filling machine for dispensing into containers. The system includes a balance tank for storing the product on the filling machine. The balance tank is in flow communication with a storage tank via a product line, and also has a level probe for monitoring the amount of product in the tank. A product pump pumps the food product to a valve mechanism which is also disposed on the product line. A programmable logic controller receives a signal from the probe indicative of the level of the product in the balance tank, and generates a series of signals to the product pump and the valve mechanism to maintain a steady flow of product from the storage tank to the balance tank. In this manner, foaming of the product in the balance tank is eliminated or substantially reduced to acceptable levels.

  • Patent number: 5920279
    Abstract: A procedure and a system increase the performance of a group of radar units. The radar units are arbitrarily located in such a way that the respective antenna beam of a radar unit functioning as a normal radar at least partially coincides with the antenna beam of at least one other radar unit in the group. The radar units are synchronised to transmit alternately and in turn, preferably with an increased energy output. All the radar units in the system are synchronised to work continuously in their ordinary reception mode. In this way at each moment echo signals originating from the radar unit transmitting at that moment are received and processed.

  • Patent number: 5907301
    Abstract: A procedure and a device for controlling, in a radar unit for the measurement of target data, the transmission of radar pulses and the reception of target echoes originating from the transmitted radar pulses, in such a way that the performance of the radar unit increases, in order thereby to gain a longer range during a period of time. The period of time is preferably repeated continually. The period of time is divided into a first and a second partial period of time where the first and the second partial periods of time are each at least twice as long as a pulse repetition interval which is used during the first partial period of time. During the first partial period of time the radar unit is controlled so that it transmits radar pulses for the measurement of target data with a higher energy content than what is possible in a steady state.

  • Patent number: 5782274
    Abstract: A cleaning box for a liquid food product filling apparatus includes a mounting member from which the plurality of filling tubes depend, and a hollow, shroud-like elliptical cylindrical body extending from the mounting member. The cleaning box is configured to, in part, shroud the filling tubes. The elliptical cylindrical body has a longitudinal axis, and is mounted to the mounting member so as to define an elliptical juncture therebetween. The elliptical cylindrical body terminates at about a free end of the filling tubes so as to define an opening. The opening is formed at an angle relative to the longitudinal axis so as to define a circular end profile. The opening is further formed such that the filling tubes are visually perceptible from a plane perpendicular to the longitudinal axis.
