Filed: 1993-12-16
Granted: 1998-11-03
Abstract: A parallel processing system is adapted to a parallel computer system and includes a plurality of processing units each having a main storage storing instructions and data, an instruction processor reading the instructions from the main storage and executing the instructions, and a transfer processor for making a data transfer in units of a packet which is made up of a header and body data, and a network coupling two processing units which are to make the data transfer based on information included in the header of the packet, where the header includes information related to at least a destination of the data, an attribute of a memory access to the main storage and a length of the data.  The transfer processor carries out a parallel process by making a data transfer between the main storage and the network in units of the packet depending on the attribute of the memory access.  The transfer processor of at least an arbitrary one of the processing units includes a managing part for managing for each user a transfer queue base address indicating a first address of a transfer queue in the main storage, a transfer queue write pointer indicating to which data transfer request of the transfer queue the instruction processor has enqueued, a transfer queue read pointer indicating to which data transfer request of the transfer queue the transfer processor has finished the data transfer process, and a memory access virtual space, and an address translator for carrying out an address translation depending on the memory access virtual space which is specified by the information included in the header of the packet and for issuing an access address with respect to the main storage, where the transfer queue is a list of headers of packets.

Title: Self oscillating dc to dc converter
Inventor: MESZLENYI IVAN
IPC: H02M3/338
Filed: 1994-05-26
Granted: 1998-09-29
Abstract: A self oscillating power converter utilizing a pair  of  MOSFET  transistor  switches  in  a  half  bridge configuration wherein the junction of the two transistors is coupled to a reactive network which in turn is connected to an output rectifier.  The gate-to-drain inter-electrode capacitance of the switching transistors serves as the sole means of sustaining oscillations.  Oscillations are started at the gate-to-source electrodes of the transistors by a startup  circuit.     The  frequency  of  oscillation  is determined  by  the  gate-to-source  capacitance  of  the transistors and the inductance of the drive transformer which  couples  the  source-to-gate  electrodes  of  the transistors to  each other.   The drive transformer  is provided with a means of varying its inductance thereby changing the switching frequency so as to regulate the voltage.

Abstract: A mechanism is disclosed for converting oscillatory rotation of an input shaft to unidirectional rotation of an output shaft.  An input shaft journalled to a frame is rotatable about an input axis, over a range of rotational positions, between a forward limit and a reverse limit.  An output shaft journalled to the frame is rotatable about an output axis, which is normal to the input axis.  Three bevel gears are employed, namely a first gear coupled to the input shaft, a second gear coupled to the input shaft and spaced axially from the first gear, and a third gear coupled to the output shaft.  The bevel teeth of the three gears are arranged in peripheral arrays covering cover less than one half of the entire periphery of each gear, so that the bevel teeth of the third gear intermesh only with the bevel teeth of the first gear whenever the input shaft rotates from the reverse limit toward the forward limit, and so that the bevel teeth of the third gear intermesh only with the bevel teeth of the second gear whenever the input shaft rotates from the forward limit toward the reverse limit.

Title: System and method for optimizing spectral efficiency using time-frequency-code slicing
Inventor: GITLIN RICHARD D
IPC: H04J13/16
Filed: 1995-03-28
Granted: 2000-01-11
Abstract: A system and method for optimizing usage of a communications transmission medium. The transmission medium may be sliced into time and frequency domains so as to create time-frequency slices for assignment to users having varying access rates and user-application requirements. Through scheduling of the various speed users within the frequency and time domains, the system and method can efficiently allocate and make use of the available spectrum, thereby accommodating higher rate users requiring greater bandwidths and time slot assignments while still preserving cost-efficient access for lower speed users. Depending on the signal modulation scheme, the time-frequency slices may be allocated on non- contiguous frequency bands. The system and method is also applicable to code-division multiple access (CDMA) techniques by slicing the available code space along time- code domains, frequency-code domains or, in three dimensions, along time-frequency-code domains. Users may be efficiently scheduled based on code space requirements so as to optimize use of the communication medium.

Abstract: A pavement marking material.comprises a flexible base sheet that is conformable to an irregular pavement surface. A non-continuous, durable, wear-resistant polymeric top layer is adhered to one surface of the base sheet. The discontinuous nature of the polymeric top layer provides for increased initial conformance of the pavement marking to irregular pavement surfaces. The discontinuous nature-of the polymeric top layer also reduces elastic tensile stresses which tend to build up in continuous top layers and cause adhesive failure. A plurality of particles, retroreflective microspheres and/or skid-resistant particles, are embedded in and protrude from the non-continuous top layer.
