In a preferred embodiment, the invention provides a circuit and method for a smaller and faster triple redundant latch. An input driver is connected to the input of two transfer gates. The output of one transfer gate is connected to an I/O of a first latch and the output of the second transfer gate is connected to the I/O of a second latch. The I/O of the first latch is connected to a first input of a tristatable input inverter. The I/O of the second latch is connected to a second input of the tristatable input inverter. The output of the tristatable input inverter is connected to the I/O of a third latch and the input of an output driver.

An integrated circuit driver includes an output stage having source drain paths of a PFET and NFET connected in series with each other across DC power supply terminals. A pair of inverters simultaneously responsive to a bilevel signal drive gate electrodes of the PFET and NFET. Each inverter includes a pair of switches and a resistor for connecting opposite polarity voltage sources to a separate capacitor connected in shunt with gate electrodes of the PFET and NFET. The inverters, resistors and capacitors prevent the PFET and NFET from being on simultaneously.

The present invention discloses a floating body architecture CMOSFET inverter with body biasing inverters added for controlling the delay time of the inverter. At least one body biasing inverter is connected between the main inverter's input and the body terminals of the FETs of the inverter. By supplying a representation of the input voltage to the body terminals of the p-channel and n-channel FETs, the preferred embodiment of the present invention is able to control the history dependent delay time associated with the variable source-to-body voltages in floating body CMOSFET inverters. The delay time is minimized by adding an odd number of body biasing inverter stages into the main inverter circuit. The delay time can also be maximized by adding an even number of body biasing inverter stages into the circuit.

An adaptive hysteresis receiver processes a high speed digital signal. A differential receiver circuit compares the high speed digital signal to a reference voltage to generate an output signal. A register circuit latches the output signal, according to a clock signal, to produce a control signal. A reference voltage generator generates the reference voltage, from a plurality of voltages defining a deep hysteresis level and a shallow hysteresis level, in response to the output signal and the control signal.

A virtual address bar user interface control is presented. The virtual address bar includes a plurality of interactive segments, each segment corresponding to a predetermined filter for selecting content in a computer file system. Collectively, the interactive segments represent a virtual address for selecting content. Selecting an interactive segment in the virtual address bar causes those segments subsequent to the selected segment to be removed from the virtual address bar. A user may select a peer filter for a segment to replace that segment's current filter and removes those segments subsequent to the updated segment. The virtual address bar can be selectively configured to operate as a conventional address bar, and reconfigured to operate as a virtual address bar. Additional filter segments are added to the end of the existing filter segments. Those existing filter segments that conflict with the added segment are removed from the virtual address bar.
摘要:
A glass ionomer or resin modified glass ionomer coated blank is combined with glass ionomer or resin modified glass ionomer to create an integral mono-block post. prefabricated glass ionomer or resin modified glass ionomer post (with or without a coated blank) is cemented into the root canal with glass ionomer or resin modified glass ionomer, thereby creating a mono-block post as well as a mono-block core. The glass ionomer or resin modified glass ionomer cement is bonded to the canal wall and also through the bonding of the cement to the post surface of similar material. An alternate methodology involves syringing glass ionomer or resin modified glass ionomer in a malleable, semi-solid state into the post preparation space and a glass ionomer or resin modified glass ionomer coated blank is then inserted into the canal to a distance substantially equal to the depth of the post preparation.

An integral, one-piece silanated particle impregnated gutta percha core/cone technique employs a thin layer of a luting agent, such as glass ionomer cement with a machined gutta percha core/cone, precisely matches the preparation, thereby reducing leakage and achieving a hermetic seal. The hermetic seal is further enhanced by a mono-block bond that occurs between the silanated particles in the gutta percha and the appropriate chemical sealant. Optional cryogenic treatment of the gutta percha material changes its molecular weight, making it stiffer and conducive to forming an integral, one piece core/cone, without the need for a separate carrier core to install the tapered gutta percha core/cone within the root canal. Additionally, the tapered body of the core/cone may be reticulated in a slightly three dimensional texturized framework to increase surface area and therefore increase retention. Optional line demarcation indicia are also placed on the core/cone. Additionally, the head of the core/cone can be gripped by a delivery vehicle clasp.

摘要:
A method and system for sampling on the fly one or more integrated circuit nodes coupled to one or more bus domain clocks of an integrated circuit using minimal clock cycle delay synchronization. Sample on the fly circuitry, set-reset circuitry and metastable rejection circuitry are used to provide a sufficient pulse width for sampling on the fly the one or more nodes when the one or more bus domain clocks require asynchronous operation. The sample on the fly circuitry is also operable to synchronously sample on the fly the one or more nodes.
