Title: Microporous polyolefin composition membrane, production method thereof and battery separator
Inventor: KAIMI NORIMITSU
IPC: H01M50/491
Filed: 1997-06-03
Granted: 2005-07-26
Abstract: A microporous polyolefin composite membrane, preferably for use as a battery separator, comprising a microporous polyolefin membrane and a polyolefin nonwoven fabric laminated on at least one surface of the microporous polyolefin membrane. The composite membrane has a thickness of 25 to 200 µm, a porosity of 30 to 70%, an air permeability of 100 to 2000 sec/100cc and a surface opening area ratio of 50 to 90% on at least one outer surface thereof. The microporous polyolefin membrane comprises a matrix polyolefin component which is a polyolefin having a weight average molecular weight of 5 × 10 5 or more or a polyolefin mixture containing the polyolefin having a weight average molecular weight of 5 × 10 5 or more, and has a porosity of 30 to 95%, an air permeability of 100 to 2000 sec/100cc, an average open pore diameter of 0.001 to 1 µm and a tensile strength at break of 500 kg/cm2 or more. The microporous polyolefin membrane may further comprise a shutdown polymer component to shut down the pores, thereby making the composite membrane impermeable. The polyolefin nonwoven fabric comprises fine fibers and has an air permeability of 0.1 to 100 sec/100cc and a basis weight of 5 to 50 g/m2. The polyolefin nonwoven fabric prevents the composite membrane from melting down at a low temperature thereby preventing the short-circuit between the electrodes.

Title: High-performance low-complexity error-correcting codes
Inventor: HUNT ANDREW
IPC: H03M13/45
Filed: 1998-08-14
Granted: 2007-06-12
Abstract: A method of encoding data is described herein. According to the method, source data elements are coded using one or more product codes having a common component code. The resulting one or more primary product codewords consist of a plurality of first codewords of the common component code. One or more first sets of codewords of the common component code are assembled such that each of the first sets comprises two or more distinct first codewords forming part of a same primary product codeword. Each of the codewords of each of the first sets is codeword-mapped to a second codeword of the common component code using a one-to-one codeword-mapping. One or more second sets of second codewords are provided, where each second set corresponds to a first set of codewords. The codeword-mapping includes re-ordering, according to a known interleaving pattern, the symbols within a codeword. The codeword-mappings are such that if all of the codewords of a first set are from a same primary product codeword, then some codeword-mappings applied to the codewords of the first set are different, and if two or more repetitions of a same codeword are included in a single first set, then the codeword-mappings applied to those repetitions are different. Each set of second codewords is coded using a systematic code so as to generate a secondary product codeword for a product code having as component codes the common component code and the systematic code. Then, the primary product codewords and the non- systematic portion of the secondary product codewords are provided as encoded output data.

IPC: G06F11/34
Filed: 1998-10-16
Granted: 2002-12-31
Abstract: The dependancies of a computer service are modeled. The modeling hierarchically defines the relationships between the computer service and the hardware and software services which the computer service depends. These relationships may be contained in data structures defining a directed acyclic graph. The model also defines which measurements need to be taken to determine health and performance of the computer service and the health and performance of all the computer services upon which the computer service depends. Software agents that take these measurements may be deployed using the model to determine the measurement locations and functions. Data from measurement agents may be propagated up the model hierarchy. The model (200) may also be visualized by a graphical interface to communicate the dependancies and the health and status of the services upon which the modeled service depends.

Abstract: A container (10) suitable for mounting on the neck of a bottle or other vessel having an annular abutment surface formed thereon and for containing a gift item consists of first and second wall sections (12,14) which are fixed together to form a generally closed space containing the gift item. One of the wall sections (14) has formed in it an opening (17) having around its periphery a plurality of elongate resilient fingers (18) projecting into the interior of the container. The fingers (18) together define a substantially frusto-conical structure such that when the neck of the bottle or other vessel is inserted into the container (10) through the opening (17) the fingers (18) are forced apart to allow passage of the neck until they have moved over the abutment surface formed on it. The ends of the plurality of fingers (18) engaged with the abutment surface to oppose movement of the neck of the bottle or other vessel out of the container. The container thus provides a secure means for securing a gift item to the neck of the bottle or other vessel as part of a promotional exercise.
