Inventor: MCHARG CHRISTOPHER G
IPC: H04L12/56
Filed: 1993-05-25
Abstract: A fast packet switch comprises one buffer (200) directly connected between a plurality of input ports and a plurality of output ports to effect rapid throughput of data packets. A pointer to a location in the buffer is allocated by a buffer manager (206) upon receipt of notification of an incoming packet at the receiving input port and the input port delivers the packet as it is received to the location designated by the pointer. After the data packet is received, the input port delivers the pointer and a destination address for the packet to a router (208), which selects one of the plurality of output ports based on the destination address. The router queues the pointer in a queue for the selected output port. The output port then retrieves the data packet from the buffer using the pointer to determine the location, and transmits the data packet. After the transmission is complete, the output port returns the pointer to the buffer manager. This packet switch may be pipelined to receive, route, and transmit simultaneously on adjacent data packets. <IMAGE>

IPC: G01S17/89
Filed: 1993-08-05
Abstract: To provide a system for the optical ranging of a selected point on a target surface irradiated with light while avoiding false signals from other sources in a cluttered. environment, the system employs a combination of the triangulation ranging technique with the Biris ranging technique, i.e. imaging onto a position sensitive photodetector through an apertured mask.      This combination enables the respective equations for range that apply to the respective techniques to be combined to generate an equation that is true only for target surface points that are directly on the light beam, hence enabling rejection of false signals on the basis of those that fail to satisfy this latter equation. The system has the advantage of flexibility, in that it permits the light beam to be directed onto the target surface from a wide range of locations relative to the detector. In addition, three dimensional data on the target surface can be obtained by using at least one further light beam inclined to the first beam and a mask with more than two apertures. For many practical applications this latter arrangement avoids a need to scan the target surface relative to the detector.

Abstract: A technique for reducing the power threshold at which stimulated brillouin scattering ("SBS") occurs within an optical fiber by directly modulating a conventional laser generating an optical signal propagated along that fiber. The modulation is accomplished by employing an alternating waveform to induce a dither upon the laser output. The specific frequency of the alternating waveform is chosen to be very much lower than the low frequency cut-off of any receiver coupled to the optical fiber, but sufficiently high enough to efficiently suppress the Brillouin gain. This dithering causes the laser to be frequency modulated, thereby broadening the effective linewidth of the laser output and increasing the SBS power threshold.

Abstract: ABSTRACT A method for registering traffic data from mobile stations (MS1, MS2) in a mobile telecommunication system (PLMN). The mobile telecommunication system includes mobile switching centres (MSC1, MSC2) and connected with these, base station controllers (BSC1-BSC4), so-called primary- and secondary base station controllers. Base stations (BTS) are connected to the base station controllers, each base station (BTS) covering a cell (CELL) and each base station controller (BSC1-BSC4) therby covering a cellarea containing several cells. Traffic data from a selected mobile (MS2) is stored in the primary base station controller of the mobile. A known problem is that registration of traffic data ceases at the same time the mobile leaves the cell area controlled by the primary base station controller. According to the present invention, a message "trace invocation" is sent from the primary base station controller to the secondary base station controller, via the mobile switching centre (MSC2), when the mobile moves to a cell handled by the secondary base station controller (BSC4). Registration of traffic data is thereafter effected in the secondary base station controller (BSC4).

Title: A method and a system for manufacturing a rigid plate material of straw or a similar material
Inventor: DJERNAES SVEND ERIK
IPC: B29C44/46
Filed: 1991-09-23
Abstract: ABSTRACT OF THE DISCLOSURE      Prior endeavours of manufacturing a straw plate material of high quality and low price have generally failed, even when the straw material is mixed with an otherwise promising binding agent consisting of a foaming plastic liquid.  The invention provides for highly improved results in not mixing the straw material with the binding agent in the normal sense of the word mixing, but injecting the binding agent in the straw layer immediately prior to the same, in a pre-compressed condition, being placed in a rigid pressing tunnel exhibiting the desired plate thickness and adapted so as to resist the expansion pressure that is produced by the subsequent foaming of the binding agent.  Hereby the binding agent will also foam itself into the straw material for impregnation thereof, whereby surprisingly good results are achievable without requirements as to any power consuming positive pressing of the material.

Title: Companding of voice signal for simultaneous voice and data transmission
Inventor: BREMER GORDON
IPC: H04L27/34
Filed: 1994-06-09
Abstract: Companding of Voice Signal for Simultaneous Voice and Data Transmission Abstract In a simultaneous voice and data communications system, a voice signal is added to a data signal before transmission over the public switched telephonenetwork (PSTN). In particular, in every signaling interval, a signal point is selected for transmission as a function of both the voice signal and the data signal. Since the voice signal is effectively offset by the data signal, compandors normally found in the PSTN are not effective in improving the signal to noise ratio of the transmitted voice and data signal. Therefore, the voice signal is additionally companded in the transmitter before transmission over the PSTN. This additional companding by thetransmitter improves the signal to noise ratio of the combined voice and data signal.

Title: Low molecular weight hair fixative polymers in low voc formulations
Inventor: GUTH JACOB J
IPC: A61K8/81
Filed: 1994-07-08
Abstract: ABSTRACT OF THE INVENTION This invention relates to the use of low molecular weight polymers in a high solids hair spray composition containing levels of volatile organic compounds 80% or lower by weight. The hair fixative polymers suitable for use in these hair sprays are based on acrylic and vinyl-ester resins that are water soluble with neutralization. The polymers have intrinsic viscosities ranging from 0.100 to 0.300 and are present in amounts ranging from 7 weight percent to 20 weight percent, based on the total weight of the hair spray composition. The use of a lower molecular weight polymer reduces the viscosity, enhances the spray characteristics, and promotes the hydrolytic stability of the system. The high solids content compensates for any lower fixative properties generally associated with lower molecular weight hair care polymers.
