Abstract: A method and system for the prevention of corrosion of objects located close to a wet cell storage battery caused by evaporation, and subsequent condensation, of electrolyte from a wet cell storage battery. Convenient methods for installation and removal of the system are included. Additionally, convenient and safe storage methods are also provided.

Abstract: A polymerization process comprises (1) contacting at least one polymerizable monomer in the presence of a metal catalyst in a reactor; (2) effectuating polymerization of the monomer; (3) adding a substituted olefin having at least one polar group to the reactor. The substituted olefin is different from the monomer. Vinyl-terminated macromers preferably are generated which can be homopolymerized or copolymerized with the monomer by the metal catalyst. A polymer of an olefin monomer and a substituted olefin comprising a backbone and a plurality of side chains. The polymer is characterized by an Rv of greater than about 0.85, where Rv is a measure of the relative number of vinyl groups in the polymer. In some polymers, the vinyl endgroups are transformed to other useful end groups.

Abstract: Methods and apparatus for storing memory test information are presented. The method includes the steps of storing a portion of information related to locations and numbers of failed memory cells detected while testing memory, and updating the stored information as failed memory cells are detected to indicate a first type of memory spare is to be assigned to repair a failed memory cell, a second complementary type of memory spare is to be assigned to repair the failed memory cell, or the memory is not repairable. The first type of memory spare corresponds to one of a row and a column portion of memory and the second complementary type of memory spare corresponds to the other of the row and column portions of memory.

Abstract: Methods and apparatus for analyzing and repairing memory are presented. The method includes the step of determining if failed memory cells detected in at least a portion of memory must be repaired using only one of a number of types of memory spares or may be repaired using any of the number of types of memory spares. Failed memory cells that must be repaired using only one of the number of types of memory spares are repeatedly repaired, skipping any failed memory cells that may be repaired using any of the number of types of memory spares, until either no new errors that must be repaired are repaired and no failed memory cells are skipped or the memory is determined to not be repairable. At least one of any failed memory cells skipped when repairing failed memory cells that must be repaired is repaired. The steps of determining if failed memory cells must be repaired and repeatedly repairing failed memory cells that must be repaired are repeated whenever at least one skipped failed memory cell is repaired.

Abstract: A method of sensing a particle in a mixture includes providing (52) the mixture (36) having a particle (29, 30), moving (54) the mixture (36) in a direction, shining (56) a light into a portion of the moving mixture (36), reflecting a portion of the light off of the particle (29, 30) in the moving mixture (36), detecting and measuring (57) the reflected light, and using (58) the measured reflected light to determine a size of the particle (29, 30).

Abstract: An 8-to-256 address signal decoder is composed of sixteen 4-to-16 output decoders. Each 4-to-16 decoder is subdivided into eight sub-functions having outputs ANDed together using sixteen OR gates. Each 4-input NAND gate of a conventional rectangular decoder is replaced by two input sub-function NANDs feeding an OR gate. The two sub-function NANDs are positioned outside a high density region, whereas the OR gates reside within a high density region below a memory cell array. The sixteen OR gates are distributed in a 4.times.4 array format. Each OR gate column is four basic cells wide, and there are four output lines for each column of OR gates to conform to dense memory cell layout criteria. The array structure requires only one vertical input line per column and one horizontal input line per row to reach each OR gate. Inverting drivers required to complete the 4-to-16 output decoders are arranged in a 4.times.4 array. The position of each inverter corresponds to the OR gate that drives it.
