摘要:
A comparison method compares the address of a memory cell with a known address of a faulty memory cell in a semiconductor memory module. The module is subdivided into banks and has an address structure in which each address is associated with a bank that is organized in rows and columns and is defined by a row address, a column address and a bank address. Not only the row address is determined, but also the column address and the bank address when a memory access occurs. A bank is activated with a bank selection signal, and the access to a valid address of a faulty memory cell is indicated by an enable register.

The present invention provides a method for making a heating element adhered to a substrate by applying a photocurable composition to a flexible substrate in a pattern having one or more grid lines. The photocurable composition is curable into an electrically conductive layer and volatile organic compounds are present in an amount of less than about 10% of the total weight of the photocurable composition. After the pattern is deposited on the substrate it is cured by illuminating the photocurable composition with light for a sufficient period of time to cure the photocurable composition. In another embodiment of the invention heating elements made by the method of the invention are provided.

The semiconductor component is provided for connection to a test system. An external clock signal with a modulated duty ratio can be input to the semiconductor component at a connection provided for that purpose on the semiconductor component. The latter has a clock recovery circuit, which obtains a periodic clock signal from the modulated clock signal, and a shift register, to which the modulated clock signal can be fed in a manner clocked by the periodic clock signal and which provides a data signal. The present invention makes it possible, in particular in mass memory chips, to feed in clock signals and also program, address or data signals for the realization of BIST via just one connection contact.

A memory configuration includes a central connection area. The central connection area is surrounded annularly by cell arrays having memory cells. The memory configuration has compact external dimensions and is suitable, in particular, for a side ratio of 2:1. All the peripheral circuits are preferably disposed in the central connection area. As a result, the propagation time differences between the peripheral circuits and the various cell arrays are relatively small.

At least two different submethods for repairing defective memory cells are used sequentially. In the submethods, the memory cells are successively tested in each case, and, directly after a defect has been ascertained, the relevant row line or the relevant column line is replaced by programming one of the redundant lines. The submethods differ in terms of their repair strategy. One submethod is called with a defect-signature which terminates the submethod and contains information about the number of checked memory cells and the repair result. Subsequently, depending on the defect-signature of the preceding submethod, another submethod is called, which initially does not cancel, partially cancels, or entirely cancels, the programming that has been performed.

摘要:
In one embodiment, contaminates are removed from a material by contacting an activated carbon fabric wetted with a solvent with the surface of the material. The activated carbon fabric is maintained in contact with the surface in a substantially vapor-tight environment to allow the solvent to dissolve the contaminants, the contaminates to diffuse in the solvent, and the contaminates to be adsorbed by the activated carbon fabric. Thereafter, the activated carbon fabric containing the contaminates is removed and the any remaining solvent is allowed to evaporate. In another embodiment, contaminates are removed from a material by maintaining a solvent wetted fabric in contact with the surface of a material, while exposing at least an upper face of the fabric to a surrounding environment to promote evaporation of the solvent. The evaporation of the solvent from the upper face migrates contaminates from the surface into the fabric where they are contained.

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.
摘要:
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 non-linear circuit element 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 non-linear circuit element switch is typically a PIN diode. The diversion circuit may be either a high pass filter or a low pass filter.
