  • Patent number: 6608030
    Abstract: Methods and products for suppressing a class II MHC-restricted immune response in a mammal, or in mammalian cells, are described. The methods depend upon inhibiting invariant chain proteolysis by cathepsin S from class II MHC/invariant chain complexes, thereby reducing the competency of Class II MHC molecules for binding antigenic peptides, reducing presentation of antigenic peptides by class II MHC molecules, and suppressing immune responses. The methods may be employed in the treatment of autoimmune diseases, allergic responses, and organ or tissue graft rejection. Pharmaceutical and therapeutic compositions which are peptide-based inhibitors of cathepsin S are also described.

  • Patent number: 6597718
    Abstract: An electroabsorption modulated laser (EML) is formed to include a Fabry-Perot lasing section, in place of the conventional DFB lasing section. When operated at a wavelength of 1310 nm, the wider spectral bandwidth of the FP device (containing several longitudinal modes) is of no concern, since 1310 nm is the zero dispersion wavelength of most conventional transmission fibers. A selective area growth process is used to simultaneously form the MQW active regions of both the FP and EA sections of the EML device, and an isolation trench may be formed between the sections to reduce the effects of electrical crosstalk.

  • Patent number: 6598164
    Abstract: As advances continue to be made in the area of high density data storage devices, the storage of such data as music (as is presently stored on audio CD-ROM's), books on tape, videos, movies and the like will become more common. However, when this type of information is stored digitally, the risk of data piracy will increase. What is needed is an integrated copy deterring mechanism for stored digitized information such as audio recordings and the like. The present invention is a digital data storage device which comprises one or more Digital to Analog Converters (DAC's). By incorporating Digital to Analog Converters on the chip or within the chip's packaging (a hybrid device), data being output could be made available in an analog form only (although some portion of the stored information could still be made available in a digital format). A device employing the analog output means disclosed could comprise read only data storage means or writable or one time programmable data storage means.

  • Patent number: 6598125
    Abstract: A method of caching information between work sessions for future use is described. The method efficiently determines those blocks of information least likely to be required for future use and preferentially discards such blocks from the cache when additional cache storage space is needed. The method also provides for the dynamic allocation of cache space between work sessions of different content.

  • Patent number: 6593957
    Abstract: Autostereoscopic image displays provide highly realistic three-dimensional images to one or a plurality of viewers without the need for wearable appliances. In some embodiments, the images are viewed through a beamsplitter, while in other embodiments the viewer observes the images on a display screen. A viewer-tracking system monitors the viewer's movements and directs each image of a stereopair to the proper eye of the viewer. In some embodiments, the stereoimages are kept independent and separately directed through differential polarization. In other embodiments, this is accomplished through selective intensity modulation.

  • Patent number: 6593796
    Abstract: A circuit to power multiple load elements is presented. Fewer discrete components and fewer output terminals are required to power multiple devices. A single high-power DC boost circuit powers multiple AC devices. An end-user can selectively power a subset of the AC devices electrically connected to the present invention. The circuit includes a first and second reference voltage terminal, and a first, second, and third switch. The circuit also includes a first control switch and a second control switch in electrical communication with the first switch and the second switch, respectively. The first control switch provides either a first control signal or a second control signal to a control terminal of the first switch. Similarly, the second control switch provides either the first control signal or the second control signal to a control terminal of the third switch.

  • Patent number: 6593641
    Abstract: Structures and methods for fabricating high speed digital, analog, and combined digital/analog systems using planarized relaxed SiGe as the materials platform. The relaxed SiGe allows for a plethora of strained Si layers that possess enhanced electronic properties. By allowing the MOSFET channel to be either at the surface or buried, one can create high-speed digital and/or analog circuits. The planarization before the device epitaxial layers are deposited ensures a flat surface for state-of-the-art lithography.
