Abstract: An input/output hub may include an interface unit and one or more communication units. Each communication unit may be configured to receive interrupts or messages from a corresponding endpoint device. A given communication unit may be further configured to synthesize a virtual address from the received message, translate the synthesized virtual address to a real address, and then translate the real address to a physical address. The interface unit may be configured to send an interrupt dependent upon the physical address.

Abstract: A method of cleaning teeth by providing a device for generating a chemical agent in situ on an as-needed basis via the application of an electrical potential across a pair of conductors in communication with an electrolyte. The chemical agents may include ozone, hydrogen peroxide, peroxide, chlorine and/or hypochlorite. The device may include a voltage source and a first set of electrodes for applying an electrical potential to the electrolyte. The device may also include a second set of electrodes disposed about an anode of the first set of electrodes. The first and second sets of anodes cooperate to produce ions, peroxides, ozone and/or other chemical agents via the application of electrical potential to the electrolyte.

Abstract: A composition is disclosed which is capable of being used for detection, comprising an encapsulated noble metal nanocluster. Methods for preparing the encapsulated noble metal nanoclusters, and methods of using the encapsulated noble metal nanoclusters are also disclosed. The noble metal nanoclusters are preferably encapsulated by a dendrimer or a peptide. The encapsulated noble metal nanoclusters have a characteristic spectral emission, wherein said spectral emission is varied by controlling the nature of the encapsulating material, such as by controlling the size of the nanocluster and/or the generation of the dendrimer, and wherein said emission is used to provide information about a biological state.

Abstract: This invention relates to compositions, and methods of use thereof, containing polyphenols such as procyanidins and derivatives thereof, for treating certain tumors, and more generally to inducing dephosphorylation of a hyperphosphorylated cell cycle regulatory protein in a tumor cell in which hyperphosphorylation of said protein contributed to cell transformation.

Abstract: A device for holding an object, and an assembly for holding and rotating an object. The device includes a base, a series of posts, each of which is equidistant from a center point of reference and further pivotably holds a follower rotationally linked to all other followers. Each follower has a gripping portion dimensioned to hold an object. An actuator serves to displace the followers radially about the post holding it creating a motion that causes the gripping portions to move either towards or away from the center reference point, dependent upon the displacement of the actuator. As all followers are rotationally linked, each follower of the device rotates to a substantially equal degree.

Abstract: Memory requests and responses thereto include a tag that has a shift value indicating the misalignment between the first byte of required packet data and the first byte of a line of data in memory. A packet buffer controller receiving data with an associated tag uses the shift value to shift the received line of data accordingly. The first line of data for the packet data payload is shifted accordingly and written into the packet buffer. Subsequent lines of data require masking the previous line of data except for the last N bytes where N equals the shift value. The shifted line of data is written over the previous line so that the lower order bytes of the shifted received line of data are written. Then the shifted line of data is written into the next line of the packet buffer.

Abstract: A bottomless trash can system comprising a trash has a tapering sidewall with a horizontal open top in a closed configuration with a first circumference and with a horizontal open bottom in a closed configuration with a second circumference greater that the first circumference. The system further includes a liner in the form of a plastic bag with a closed lower end positioned within the trash can adjacent to the bottom and an open upper end positioned over the top of the trash can and extending downwardly to a location beneath the open top. The system also includes an elastic band positioned over the liner and side wall adjacent to the upper end to hold the inner in proper orientation with respect to the trash during operation and use.

Abstract: A method for synchronizing data transfers in a data processing system is presented. The invention includes two separate clocks generated by a slave processor, one of which is used to synchronize outgoing signals from the communicating elements and the second of which is used to synchronize incoming signals to the communicating elements.

Abstract: A protocol for transferring instructions between asynchronous processors in a computer system is provided. Each instruction transfer requires the transfer of an opcode and a variable number of operands. The transfer is accomplished via a bus which interconnects the processors. The opcode and operands are assembled in a buffer in the sending processor and then transferred to the receiving processor in reverse order, i.e., operands first and opcode last. The receiving processor does not acknowledge any of the transfers until it receives the opcode which is always sent last. Upon receipt of the opcode, the receiving processor knows the instruction transfer is complete and sends the acknowledge signal immediately thereafter.

Abstract: A digital data processing system transfers information with an external device through an interconnect unit over a bus which includes separate sets of lines for transferring control information and transferring user information. The user information lines include bidirectional information transfer lines and undirectional antiparallel lines for transferring direction control signals and synchronization signals between the interconect unit and the external device, the direction control signals indentifying the direction of transfer over the information transfer lines, and the synchronization signals identifying when the transmitting unit has transmitted the signals and when the receiving unit has latched the signals. The control information lines include unidrectional antiparallel lines for transferring control information and a synchronization signal. The synchronization signal is transmitted when control information signals are being transmitted on the control information lines.
