  • Patent number: 6219729
    Abstract: An apparatus is employed for providing for efficient communication between high level and low level processing engines in a disk formatter for formatting a disk, the high-level engine outputting at least one instruction to control disk operations to the low-level engine which processes the instruction. The apparatus includes an instruction queue within the low-level engine. The instruction queue stores the instruction received by the low level processing engine from the high level processing engine, which outputs the instruction to the memory in accordance with a first clock signal generated by the high-level engine. The instruction queue outputs the instruction in accordance with a second clock signal of the low level processing engine which corresponds to a predetermined disk transfer rate. In accordance with another embodiment of the present invention, a method is also employed for providing for efficient communication between high and low level processing engines in a disk formatter for formatting a disk.

  • Patent number: 6219695
    Abstract: An audiovisual communications configuration comprising an interface (28) for receiving from a computer (10) a video signal output by video circuitry (15) of the computer. In this context, the video signal is output by the video circuitry of the computer for displaying an image on a first screen display (18), and the computer includes a microprocessor (15). The audiovisual communications configuration further includes circuitry (64, 66, 68, 70) for coupling a video data signal to a telephone line (40). This circuitry for coupling a video data signal is controllable independently from the microprocessor. The video data signal is representative of the video signal output by the video circuitry. Moreover, the video data signal is configured to be received from the telephone line and decoded to display an image on a second screen display (42) remote from the first screen display. Lastly, the image on the second screen display is representative of the image on the first screen display.

  • Patent number: 6219688
    Abstract: A method for forming a sum of the absolute value of the difference between each pair of numbers of respective first and second sets of numbers. The method includes forming the difference between a first number of the first set and a second number of the second set. Next this difference is either added to or subtracted from a running sum based upon the sign of this difference. This is repeated until all number pairs are either added to or subtracted from the running sum of absolute values of the differences. The initial subtraction is used to set a status bit in a flag register (211) based upon a less than zero output or the carry-out. The status bit controls whether the difference is added to or subtracted from the running sum. The conditional addition to or subtraction from the running sum may generate a carry-out representing the most significant bit of the running sum. This carry-out is stored and later added to the running sum to recover the most significant overflow bits.

  • Patent number: 6219378
    Abstract: A method of initializing the operation of a remote modem (10) and central office modem (20k) for asymmetric subscriber line modem communications over a twisted pair wire facility (TWP), using discrete multi-tone technology, is disclosed. The initialization process begins with the remote modem (10) issuing an initialization request, in response to which the central office modem (20k) issues an acknowledgment. The remote modem (10) includes a low-cost analog filter (21) for separating upstream communication echoes from downstream data. This analog filter (21) increases the duration of impulse response over the channel, and thus requires time-domain equalization (TEQ) process (31) performed by the remote modem (10) to filter relatively long circular prefixes, so that intersymbol interference is eliminated.

  • Patent number: 6218277
    Abstract: An integrated circuit includes a substrate (12) having a conductive region (18), and includes a dielectric layer (19) disposed over the substrate. An upwardly tapering frustoconical opening (22) is created through the dielectric layer to the conductive region. A barrier layer (31) is then applied, after which a thin metal layer (32) is applied, the upper end of the opening being pinched off or closed by the metal layer. Heat and pressure are then simultaneously applied, so that the metal layer flows to completely fill the available space within the opening. Selected portions of the metal layer external to the opening are then etched away. A further dielectric layer (41) is applied over the barrier layer and metal layer, and then planarization is carried out on the further dielectric layer.

  • Patent number: 6215437
    Abstract: For reading the data stored in a transponder by means of an interrogation device, the interrogation device at first receives the background noise for the purpose of detecting interference frequencies present in this background noise. On the basis of the interference frequencies acquired, coefficients for an adaptive filter are computed by means of which this filter may be tuned in such a way as to suppress the interference frequencies. The response signal from the transponder with the superimposed background noise is received by the interrogation device and routed through the adaptive filter which acts to suppress the interference frequencies. The signal available at the output of the filter can then be demodulated for the purpose of reading the data stored.

  • Patent number: 6214696
    Abstract: The method includes forming a pad oxide, a polysilicon layer over a substrate. Next, an oxide layer is formed over the polysilicon layer. An opening is formed in the oxide layer, the polysilicon layer, and the pad layer. A trench is formed by etching the substrate using the oxide layer as a mask. A sidewall structure is then formed on the opening. Next, an exposed portion of the substrate is etched by using the sidewall structure as a mask. The sidewall structure and the oxide layer are then removed. An oxide and an oxynitride layer are then formed on the aforesaid feature. A semiconductor layer is then formed over the oxynitride layer. A portion of the semiconductor layer is oxidized for forming an insulating layer. Finally, a refilling layer is formed over the insulating layer and the substrate is planarized for having a planar surface.

  • Patent number: 6215650
    Abstract: A preferred embodiment of this invention includes an oxidizable layer (e.g. tantalum 48), an oxygen gettering layer (e.g. platinum/tantalum mixture 34) overlaying the oxidizable layer, a noble metal layer (e.g. platinum 36) overlaying the oxygen gettering layer, and a high-dielectric-constant material layer (e.g. barium strontium titanate 38) overlaying the noble metal layer. The novel structures presented provide electrical connection to high-dielectric-constant materials without the disadvantages of current structures. The oxygen gettering layer controls oxygen diffusion, minimizing the formation of a resistive layer either in the lower electrode or at the lower electrode/substrate interface. The oxygen gettering layer acts as a gettering site for oxygen, where the oxygen oxidizes the reactive metal portion of the layer, leaving the noble metal portion of the layer intact. While the oxides/suboxides (e.g.
