Abstract: A reclosable film structure for a package is disclosed, in particular a reclosable lap seal, comprising a multiple layer film with an interior pressure sensitive adhesive layer, and methods of manufacture thereof. The pressure sensitive adhesive layer is positioned between a first and a third layer on either side of the pressure sensitive adhesive layer and is continuous throughout the package. The package is heat sealed at an open end to initially close the package by folding over an outer lap seal segment onto an inner lap seal segment and heat-sealing together. Upon opening the package at the lap seal, the package delaminates between the first and second layers along one of the lap seal segments, thus exposing the pressure sensitive adhesive layer to facilitate reclosing the package, oriented away from the package interior and away from the food removal path to maintain the adhesion strength by avoiding food contact.

Abstract: A faucet is provided comprising in-service separable parts that can be removed from the faucet without having to remove the entire housing. The faucet includes a main support housing, bolts, brackets and nuts to secure the main support body to a sink surface, two water inlets for connecting hot and cold incoming water lines. A flow control assembly is provided at each inlet to regulate the hot and cold water introduced into a mixing chamber. The valve housing includes an independent adjustable mixing valve for regulating the flow of water, an inline screen filter for removing particulate matter from the water stream, and a check valve for preventing water from returning back to the water source. Upon passing through the check valve and into water mixing housing inlets, the water is mixed in a mixing chamber. From the mixing chamber the water is regulated by a solenoid. When sink users place their hands, or other objects in front of the sensor the solenoid is activated.

Abstract: A decoding system which is arranged to perform a plural-stage process in determining which of the driver lines to stimulate in response to each electrode address value supplied to the decoder. This enables the network configuration of the impedances to be machine generated, and also enables the decoder to calculate on the fly which driver lines to stimulate in response to each address value. Furthermore, different resolutions may be provided to enable groups of the electrodes to be addressed simultaneously. Such a decoder arrangement may also be used with an electrode arrangement in which each electrode is connected to only two of the driver lines, in order to achieve addressing schemes in which up to t consecutive electrodes can be driven simultaneously. The invention is applicable, for example, to liquid crystal displays, arrays of memory elements and arrays of sensors such as light-sensors.

Abstract: A fault-tolerant magnetoresistive solid-state storage device (MRAM) in use performs error correction coding and decoding of stored information, to tolerate physical defects. At manufacture, the MRAN device is tested to confirm that each set of storage cells is suitable for storing ECC encoded data, using either a parametric evaluation (step 602), or a logical evaluation (step 603) or preferably a combination of both. Failed cells are identified and a count is formed, suitably in terms of ECC symbols 206 that would be affected by such failed cells (step 604). The count can be compared to a threshold (step 605) to determine suitability of the accessed storage cells and a decision made (step 606) on whether to continue with use of those cells, or whether to take remedial action.

Abstract: A magnetoresistive solid-state storage device (MRAM device) uses storage cells 16 arranged in many arrays 10 to form a macro-array 2. For fast access times and to reduce exposure to physical failures, each unit of data (e.g. a sector) is stored with a few sub-units (e.g. bytes) in each of a large plurality of the arrays 10. Advantageously, the plurality of arrays 10 are accessible in parallel substantially simultaneously, and a failure in any one array affects only a small portion of the data unit. Optionally, error correction coding (ECC) is employed to form encoded data with symbols which are stored according to preferred embodiments which further minimise exposure to physical failures.

Abstract: A fault-tolerant magnetoresistive solid-state storage device (MRAM) in use performs error correction coding and decoding of stored information, to tolerate physical failures. At manufacture, the device is tested to confirm that each set of storage cells is suitable for storing ECC encoded data. The test comprises identifying failed cells where the failures will be visible in use for the generation of erasure information used in ECC decoding, by comparing parametric values obtained from the cells against one or more failure ranges, and includes performing a write-read-compare operation with test data to identify failed cells which will be hidden for the generation of erasure information in use. A failure count is formed based on both the visible failures and the hidden failures, to determine that the set of cells is suitable for storing ECC encoded data. The failure count is weighted, with hidden failures having a greater weighting than visible failures.

Abstract: Contamination of an automatic faucet with bacteria, e-coli and other harmful materials is avoided by coating inlet screens of such faucets with silver. Contact of the silver coating with water borne contaminants within the faucet removes most harmful contaminants in the water. A screen structure particularly suited for insertion in the water inlet of automatic faucets is disclosed.

Abstract: A magnetoresistive solid-state storage device (MRAM) employs error correction coding (ECC) to form ECC encoded stored data. In a read operation, parametric values are obtained from storage cells 16 of the device and compared to ranges to establish logical bit values, together with erasure information. The erasure information identifies symbols 206 in a block of ECC encoded data 204 which, from the parametric evaluation, are suspected to be affected by physical failures of the storage cells 16. Where the position of suspected failed symbols 206 is known from this erasure information, the ability of a decoder 22 to perform ECC decoding is substantially enhanced.

Abstract: A magnetoresistive solid-state storage device (MRAM) employs error correction coding (ECC) to form ECC encoded stored data. ECC encoded data is read and decoded to identify failed symbols. A failure history table is then updated to indicate columns 14 of an array of storage cells 16 which are suspected to be affected by physical failures. Advantageously, erasure information is formed with reference to the failure history table, and the ability of a decoder 22 to perform ECC decoding is substantially enhanced.

Abstract: A magnetoresistive solid-state storage device (MRAM) performs error correction coding (ECC) of stored information. Since currently available MRAM devices are subject to physical failures, data storage arrangements are described to minimize the affect of those failures on the stored ECC encoded data, including storing all bits of each symbol in storage cells 16 in one row 12 (FIG. 3), or in at least two rows 12 but using storage cells 16 in the same columns 14 (FIG. 4). Sets of bits taken from each row 12 are allocated to different codewords 204 (FIG. 5) and the order of allocation can be rotated (FIG. 6). A second level of error checking can be applied by adding a parity bit 226 to each symbol 206 (FIG. 7).

Abstract: A check sum calculation on data coded with a Reed-Solomon error correcting code is performed by applying a byte based polynomial remaindering process to data bytes. The polynomial is X2+X?2+?, over GF (28), where ? is the primitive element GF (28) used to define redundancy coding for individual data groups. The roots of the polynomial used in the polynomial remaindering process differ from the roots of a generator polynomial of the Reed-Solomon error correcting code. The polynomial remaindering process is performed with a sub function mask containing the same mask function as used in defining redundancy coding for a data group or groups. The data group or groups are redundance coded using a Reed-Solomon code over GF (28).
