  • Patent number: 5586179
    Abstract: Disclosed is a system and method for adding and integrating outbound calling and overall system control to an existing inbound telephone system. The existing inbound telephone call distribution system is coupled to a number of telephone lines, and connects incoming calls to an available operator having a voice signal processing unit. The present system detects at least one available operator and an absence or a threshold condition of incoming calls to connect to the operator. An automated telephone dialer, coupled to the inbound call distributor, is also provided. The automated telephone dialer is responsive to the detection of at least one available operator and the absence or threshold condition of incoming calls to connect to the operator, for placing an outbound telephone call. The system directs that the voice portion of an answered outbound telephone call be connected to the existing voice signal processing unit of the available operator.

  • Patent number: 5421339
    Abstract: Apparatus and in vivo methods to distinguish normal and abnormal cervical tissue and to detect cervical intraepithelial neoplasia (CIN) in a diagnostic cervical tissue sample. Induced fluorescence intensity spectra from known normal cervical tissue and a diagnostic tissue sample are obtained from the same patient. Peak fluorescence intensity values for normal tissue samples are averaged, as are slope measurements from predetermined portions of spectra induced in both known normal cervical tissue and the diagnostic tissue sample. Peak fluorescence intensities of diagnostic tissue spectra are divided by average peak fluorescence intensity values for normal tissue in the same patient to yield relative peak fluorescence intensity values. Normal and abnormal cervical tissues are distinguished using a predetermined empirical discriminant function of slope measurements derived from normal tissue spectra and relative peak fluorescence intensity measurements in the same patient.

  • Patent number: 5410342
    Abstract: A printhead (1) for a continuous ink jet printer has a single pair of nozzles (3,3'). One or more oscillators for vibrating the ink (3,3') may be used to break up the twin streams (4,4') of droplets issuing from the nozzles. A pair (5) of charging gates is provided for applying, selectively and respectively, a charge to droplets in the two streams (4,4'). A pair of deflector means (7) apply respective electric fields across the streams (4,4') to deflect the droplets individually in accordance with the charge thereon. A gutter (10) or pair of gutters (11,11') receive droplets from the respective streams if they are not charged. The arrangement is such that the two streams of droplets are deflected in opposite directions so as to be printed.

  • Patent number: 5323335
    Abstract: A Kalman filter, for a dynamic system having a number N of different states and another number M of observational components, uses a fixed rectangular systolic array of N.times.(N+1) parallel data processing elements for a regular filter, and uses an array of (N+2).times.(N+3) processing elements for a fault-tolerant filter; the processing elements in either configuration are connected in a four-nearest-neighbors network. Each processor is capable of carrying out a commanded one of a plurality of different vector-data operations sets during each of eight passes through the array. The systolic array operates on the matrices in a pipeline manner, so that each pass through the processor array feeds the result back into the array to begin the next computation.

  • Patent number: 5253716
    Abstract: A fog producing firefighting tool has a nozzle which includes a plurality of apertures oriented so that when pressurized fluid flows through each aperture, the liquid impacts at an angle of 90 degrees with another stream of liquid to atomize the liquid and create a fog. The firefighting tool is of modular construction which includes a first member, one or more intermediate members, and an end member wherein the members are connected to each other by means of quick coupler devices which can be readily locked into coupled relationship and will not interfere with the usage of the tool when it is forced into or removed from a hole in a structure.

  • Patent number: 5153310
    Abstract: Biologically active analogs of human IL2, which differ from natural IL2 by the substitution of amino acid residues to form N-linked glycosylation sites in the molecule, are prepared by recombinant DNA techniques. Such analogs of IL2 are N-linked glycosylated when expressed in eukaryotic cells. Natural IL2 is not N-linked glycosylated.

  • Patent number: 5147325
    Abstract: The present invention relates to a shield for use on a prefilled hypodermic syringe assembly. The shield is intended to be retrofitable over a sheath/needle sub-assembly of the hypodermic syringe assembly in such a manner that insertion of the sheath/needle sub-assembly into the shield can be simply and easily accomplished by a medical worker, and subsequent extraction of the sheath from the shield is prevented by retention members which are formed from the housing of the shield, and which protrude into the chamber to hold the sheath. The retention member are formed so as to allow the sheath to be slidable into the chamber of the shield, yet engage the exterior surface of the sheath to resist extraction thereof once the sheath has engaged the retention members.
