  • Publication number: 20050232307
    Abstract: A transmission arrangement and method permits time-sensitive data to be transmitted through a packet-switched network and arrive synchronously at separate end points without synchronising all payload carrying nodes in the network. This is achieved by propagating a timing reference through the network from the sending node to the end nodes, each end node adjusting that phase of its local frequency generator to this timing reference. The sending node then sends data structure information to the end nodes, enabling the end nodes to regenerate the timing and structure of the synchronous data stream. Finally delay information is sent to each end node that allows the end nodes to adjust the start of synchronous data transmission by an amount such that all will commence transmission substantially simultaneously. With this information the end nodes independently recreate a signal in synchronisation.

  • Patent number: 6560239
    Abstract: A method and system enables a packet-switched data communication in a wireless communications system to be quickly and easily reestablished after interruption. The computer communications protocol that has been negotiated during the establishment of the packet-switched data communication may be saved upon interruption and later restored. In an exemplary embodiment, a wireless subscriber activates a call-waiting-type service along with an option to retain a packet-switched data communication. Thereafter, the subscriber may be engaged in a data communication on a packet data channel of the wireless communications system. Acceptance of a subsequent incoming, circuit-switched voice call causes the data packet session to be suspended, but the negotiated parameters of the computer communications protocol are saved. After the subscriber terminates the voice call, another data packet session is established with the saved parameters without needing to renegotiate the computer communications protocol parameters.

  • Patent number: 6545749
    Abstract: The invention relates to an electronic distance measuring device which measures the propagation time to and from a target of a shor pulse of a trasmitted electromagnetic beam from a radiation source comprising a microchip laser, and comprising objective optical system (6; 16; 21); for the reflected beam from the target and a detecting unit (9; 13; 20) to which the received beam is transmitted. Means (4, 5; 15) is provided for making the transmitted and the receiving electromagnetic beam coaxial. Means (6, 10, 12; 14, 16; 21, 22) are also provided for focusing the received beam onto the detecting unit (9; 13; 20). A means (3) makes the transmitted electromagnetic beam simultaneously as narrow and as collimated as possible in order to get a well-defined radiation measuring spot on the target.

  • Patent number: 6253881
    Abstract: An adjustment device for an item of furniture comprises two relatively mutually movable parts of which the one is elongate, cylindrical and longitudinally displaceable in relation to the other. A helical spring is disposed with pretensioning about a split sleeve which grips the cylindrical portion. At least one end of the spring is disposed for cooperation with an abutment in communication with the second part. An operating device is connected to the spring for realizing, on actuation between the ends of the spring and about the center axis of the spring, a relative rotational movement which is counter-directed to the pretensioning.

  • Patent number: 6210897
    Abstract: The present invention relates to an isolated nucleic acid molecule encoding canine leukocyte integrin &bgr;-2 subunit having a Cys36Ser missense mutation, wherein the missense mutation is indicative of a carrier of canine leukocyte adhesion deficiency. The present invention also relates to a method for identifying dogs which are carriers of or are affected with canine leukocyte adhesion deficiency. This method includes obtaining a biological sample from a dog and testing the biological sample for a Cys36Ser missense mutation in a gene encoding leukocyte integrin &bgr;-2 subunit, wherein the missense mutation in one allele is indicative of a carrier of canine leukocyte adhesion deficiency and the missense mutation in both alleles is indicative of a dog affected with canine leukocyte adhesion deficiency.

  • Patent number: 6183955
    Abstract: Coat color is important to the pig breeding industry for a number of reasons. It is therefore desirable to develop populations of pigs which will breed true for coat color. However, establishing such populations would be time-consuming and costly using traditional test mating programs. It is therefore desirable to determine the coat color genotype of individual pigs. The inventors have shown that the KIT gene in pigs is involved with coat color determination. Specifically, the inventors have discovered that the difference between the I, IP, and i alleles of the coat color determining gene is duplication of at least part of the KIT gene in the I and IP alleles. Further, the inventors have discovered that the difference between the I and IP alleles is that, although both I and IP have a duplication in the KIT gene, only I and not IP exhibits a deletion in one of the duplicated regions.

  • Patent number: 6106278
    Abstract: The object of the invention is to provide a novel combustion chamber which has an improved air supply and also ensures an optimum incident flow to the burners when the mass flows of cooling and combustion air are different. According to the invention, this is achieved in that the at least one cooling duct (10) is extended right into the plenum (13) and is formed inside the plenum (13) as a diffuser (14) having an orifice (12) leading into the plenum (13). The at least one opening (15, 15') in the burner dome (4) is arranged in the region of the diffuser (14) or directly downstream of its orifice (12). A bypass duct (16, 16') having an orifice (17, 17') leading into the plenum (13) follows downstream of each opening (15, 15'). The orifice (17, 17') of each bypass duct (16, 16') is oriented at least approximately in parallel with the orifice (12) of the diffuser (14) and is also designed so as to be offset step-like to the outside.

    Abstract: An arrangement for one-man surveying, including a measuring station (1) and a target unit (2). A sighting-marker arrangement is provided which can be indicated by an indicator arrangement (7) on the measuring station. The measuring station (1) automatically takes a target seeking mode when the indicator arrangement (7) does not indicate the sighting-marker arrangement and a target following mode, when the indicator arrangement indicates the sighting-marker arrangement. The sighting-marker arrangement includes a combination of a first and a second sighting-marker unit. The first unit has a light source (8) on the target unit (2). The second unit has a light source (9) on the measuring station (1) and a reflector (11) on the target unit (2).
