The invention relates to a method for distributing computing time in a computer system on which run a number of partial processes or threads to which an assignment process or scheduler assigns computing time as required, priorities being associated with individual threads and the assignment of computing time being carried out according to the respective priorities. According to said method, the individual threads are respectively associated with a number of time priority levels. A first time priority level contains threads to which computing time is assigned as required at any time. A first scheduler respectively allocates a time slice to the individual time priority levels, and respectively activates one of the time priority levels for the duration of the time slice thereof. A second scheduler monitors the threads of the first time priority level and the threads of the respectively activated time priority level, and assigns computing time to said threads according to the priorities thereof.

An energy management system that facilitates the transfer of high frequency energy induced on an implanted lead or a leadwire includes an energy dissipating surface associated with the implanted lead or the leadwire, a diversion or diverter circuit associated with the energy dissipating surface, and at least one switch for diverting energy in the implanted lead or the leadwire through the diversion circuit to the energy dissipating surface. In alternate configurations, the switch may be disposed between the implanted lead or the leadwire and the diversion circuit, or disposed so that it electrically opens the implanted lead or the leadwire when diverting energy through the diversion circuit to the energy dissipating surface. The switch may comprise a single or multi-pole double or single throw switch. The diversion circuit may be either a high pass filter or a low pass filter.

Automatic trend analysis is provided on a dataset. Upon selection of a data cell or chart point within a data representation, a trend chart is automatically generated in order to demonstrate how the data within the selection trends over time. The system may automatically configure the trend chart based on the metadata of a data source associated with a selected data such that no input or configuration is needed by a user. The system may identify the time hierarchies and other data attributes included in the metadata of the data source associated with a selected data cell and may automatically configure the axis settings and the trend lines according to metadata of the data source. The trend chart may also be configured to display multiple trend lines for comparing multiple data set trends over a specified time period.

Ultrasonic solvent cleaning processes can effectively decontaminate sensitive equipment. The disclosed decontamination liquids meet the following criteria: a. It is compatible with a wide range of sensitive equipment—the performance of electronic and optical equipment is not affected by immersion in decontamination liquid. b. The principal chemical warfare agents of concern are sufficiently soluble in decontamination liquid for it to be an effective decontamination medium. c. The principal chemical warfare agents of concern are quantitatively removed from solution in decontamination liquid by activated carbon. When agent contaminated decontamination liquid is passed through a bed of activated carbon, the agent adsorbs onto the activated carbon, resulting in agent free decontamination liquid that can be recycled and reused. d. It is nonflammable, nontoxic, and environmentally acceptable. Ultrasonic agitation provides effective mass and physical transfer of contaminants from the surfaces of the objects being decontaminated to the bulk of the decontamination liquid.Contaminant removal occurs in three steps: removal of the contaminant from the surface of the part being processed, transfer of the dissolved or suspended contaminant into the bulk of the decontamination liquid in the immersion sump, and then removal of the dissolved contaminant by activated carbon adsorption, or suspended contaminant by filtration.Biological contaminants are also effectively removed or inactivated by immersion and sonication in decontamination fluid or solutions of a soluble surfactant in decontamination fluid.Activated carbon beds and filters that come into contact with contaminated liquid can be contained in commercially available housings that shield the system operator from any contained toxic contents. These sealable containers, and their contents, can be destroyed by standard methods, such as incineration.Spectrographic fluorimetry can detect extremely low levels (of the order of 10 ppt) of fluorescent dyes dissolved in decontamination fluid.Decontamination of sensitive equipment in decontamination fluid can be performed in commercially available ultrasonic vapor degreasers.

The invention relates to a semiconductor module having a plurality of signal paths for carrying external signals that each contain a setup and hold circuit on the basis of a latch circuit with a full latch and a logic circuit. The latch circuit contains at a beginning of the signal path upstream of the logic circuit a hold latch. The hold latch responds to the leading edge of a fast clock signal derived from the clock signal of the external signal, for the early latching of the external signal and for the decoupling of the hold time from the setup time. The full latch is disposed downstream of the logic circuit for the final latching of the external signal or of a signal derived from the latter.

A circuit includes a programmable element having conductor track resistance that can be permanently altered by an electric current. The circuit also has a switchable element for receiving a control signal for programming the programmable element. The programmable element and the switchable element are connected in series between two supply potentials. The programmable element can have an electrical fuse. The input of a read-out circuit is connected through a protective circuit to the circuit node between the programmable element and the switchable element. The protective circuit serves for limiting the voltage potential at the input of the read-out circuit during a programming operation. The circuit elements of the read-out circuit can thus be dimensioned in an area-saving manner. The protective circuit also can include a diode having an anode connected to the input of the read-out circuit and a cathode connected to a third supply potential. The protective circuit can include resistors, one disposed between the anode and input of the read-out circuit and another disposed between the anode and the circuit node.
摘要:
An integrated circuit has a first control unit for controlling the threshold potential of the transistors of a first conductivity type. In addition, it has a second control unit for controlling the threshold potentials of the transistors of a second conductivity type. The required value input of the second control unit is supplied with a required value for the threshold potential of the transistors of the second conductivity type, which is proportional to the actual value of the threshold potential of the transistors of the first conductivity type. Due to the dependence of the second control unit on the control by the first control unit, improved switching characteristics of the integrated circuit are achieved.
