Title: Integrated single chip dual mode raid controller
Inventor: JANDER MARK J
IPC: G06F13/10
Filed: 1998-09-29
Granted: 2002-05-28
Abstract: A RAID controller integrated into a single chip (100). The RAID controller chip (100) includes a general purpose RISC processor (121), memory interface  logic (128), a host CPU PCI bus (150), at least one back-end I/O interface channel (130), at least one direct memory access (DMA) channel (122), and a RAID parity assist (RPA) circuit (126). The RAID chip enables higher integration of RAID functions within a printed circuit board and in particul ar enables RAID function integration directly on a personal computer or workstation motherboard. The back-end I/O interface channel is preferably du al SCSI channels. The RAID chip is operable in either of two modes. In a first mode, the chip provides pass through from the host CPU (102) interface directly to the dual SCSI channels (130). This first mode of operation, a SC SI pass-through mode, allows use of the chip for non-RAID storage applications and enables low level manipulation of the disk array in RAID applications of  the chip. The first mode of operation permits use of the chip without change  to host applications and drivers. Rather, the chip is operable in a manner compatible with known available SCSI controller devices. The second mode of operation, a RAID control mode, provides full RAID management features to th e attached host CPU. In thepreferred embodiment, the RAID chip presents an Intelligent I/O (I2O) interface to the host CPU to enhance portability and performance of the host/RAID interaction.

Granted: 2008-01-22
Abstract: A system and method for supporting communications among multiple intercon- nected networks (10, 12, 13, 14) include assigning multiple dynamic telephony addresses to each wireless communication device (34) that registers in more than one network. The networks assign the addresses independently of each other. When an incoming call is directed to a particular wireless device via a first network, if the wireless device is beyond the transmission range of the first network, a locate-wireless-communication-device message may be single-cast, multicast or broadcast to remote networks, with instructions to return dynamic telephony addresses assigned to the device. While the telephony addresses are different in each network, each wireless device is associated with a device identifier that is universally applied in the internetwork. Upon receiving a telephony address from a remote network, the address is stored in local memory at the first network, thereby allowing access for subsequent incoming calls.

Title: Methimazole derivatives and tautomeric cyclic thiones to treat autoimmune diseases
Inventor: KOHN LEONARD D
IPC: C12Q1/68
Filed: 1999-08-27
Granted: 2009-11-17
Abstract: The present invention provides methods for treating autoimmune diseases in mammals and for preventing or treating transplantation rejection in a transplant recipient. These methods utilize specifically-defined methimazole derivatives and tautomeric cyclic thione compounds, as well as pharmaceutical compositions containing those compounds.  These compounds and compositions have been found to be at least as effective as methimazole in terms of pharmaceutical activity, while having less of an adverse effect on thyroid function. They are also more soluble in conventional pharmaceutical vehicles than methimazole. An assay for screening the activity of compounds useful against autoimmune diseases (ability to suppress expression of MHC Class I and II molecules) is also taught.
