Title: Versatile interface smart card
Inventor: SARAT JEAN MARC
IPC: G06K19/07
Filed: 1999-03-17
Abstract: A smart card (18) that is compatible with multiple different protocols includes a standard set of contacts (20) that comply with the protocols of published standard, and another contact (32) not designated by the standard which is used to indicate whether the card is to operate in a non-standard mode. When the card is to operate in the non-standard mode, a simple start-up procedure is employed which does not require strict timing constraints, enabling a less expensive interface device to be used. The interface device can be connected to any bus of a computer (14) which operates in accordance with a desired non-standard protocol. Due to the flexibility and functionality offered by smart cards that have microprocessors (24) incorporated therein, the multi-protocol smart card can be used to drive, or otherwise communicate with, any of a variety of peripheral devices, whether or not a personal computer is present in the system.

Abstract: A securement device is provided for securing a catheter to a patient's skin.  An elongated handle member is used to align and apply the device to the patient's skin. A cover dressing is releasably attached to the handle member  and has a covering side configured for placement against the patient's skin to cover at least the entry wound created by the catheter. The holder includes a securing member with a first side having an adhesive thereon for securing to  the patient's skin adjacent to the point of entry of the catheter through th e skin.

Patent CA-2330080-A1 (CA)
Title: Ambient light detection technique for an imaging array
Inventor: SCOTT-THOMAS JOHN
IPC: H04N5/335
Filed: 2001-01-03
Abstract: This invention is directed to a method and apparatus for determining the level of ambient light impinging on a selected number of pixels in an imaging array where each pixel includes a photodiode. The ambient light may be determined by resetting the pixels in the array and by detecting current flow through the photodiodes in a selected number of the pixels as they are being reset. Alternately, the ambient light may be determined by resetting a selected number of the pixels in the array and by detecting current flow through the photodiodes in the selected number of the pixels as they are being reset. The photodiodes are reset by applying a reverse bias voltage across them and the current flow is detected measuring the current flow through a resistance in parallel to the selected photodiodes. The selected number of pixels may be divided into one or more groups each having at least one pixel, and the pixels in each group may be arranged in specific patterns within the array. The array may be laid out in rows and columns, and the groups may be located in predetermined rows or columns. When only a selected number of pixels are reset and these pixels are divided into groups, the groups may be sequentially reset to permit differentiation between the groups.
Patent CA-2331142-A1 (CA)
Inventor: WEBSTER MARK
IPC: H04B1/7115
Filed: 2001-01-16
Abstract: The performance of a RAKE receiver for indoor multipath WLAN applications on direct sequence spread spectrum signals having relatively short codeword lengths comprises a channel-matched filter and codeword correlator front end, plus a signal combiner to which the codeword correlation component is applied. The signal combiner is supplied with a bias-corrected input calculated by a distorted codeword signature (power) generator, which is operative to generate and store a set of N codeword power correction values.  The signal combiner combines correction values into the codeword correlation for each potentially transmitted codeword S k. This serves to correct each correlation codeword metric by a de-biasing power component ¦S k¦2 far the unequal multipath-based distortions of the codeword energies. The output of the signal combiner is coupled to a peak detector, which selects a minimum distance-based 'de-biased' output as the transmitted codeword.

Title: Processes for preparing precipitated calcium carbonate compositions and products thereof
Inventor: MOLLER KURT H
IPC: B01F23/70
Filed: 2001-05-14
Abstract: Processes for making high quality PCC compositions, and the resulting PCC  products thereof. A precipitated calcium carbonate (PCC) composition is prepared by a process comprising the step of wet media mill grinding an aqueous slurry of PCC made by carbonation of lime milk, with the grinding being done at a low solids content in a plurality of separate grinding stages, which can done while essentially free of the presence of organic dispersant. After the multi-stage wet grinding step, the ground PCC slurry is partially dewatered in the presence of an organic dispersant in a solid bowl centrifuge. Then, the partially dewatered PCC slurry is subjected, in the presence of an organic dispersant, to fluid shearing forces created in a rotor/stator type mixer. While these three steps are advantageously used together within a single PCC process flow for optimal effect, the individual steps also can be incorporated singly or in lesser combinations thereof into different PCC manufacturing schemes to beneficial effect. The resulting PCC compositions are endowed with reduced high-shear viscosity in aqueous slurry form at high solids content and contain PCC particles of narrower particle size distribution. PCC slurries are provided that are particularly well-suited for paper coatings applications including medium and low coating weight, woodfree paper coatings, although it has wider applicability and is by no means limited thereto. As another aspect, the additional cost otherwise associated with the use of evaporative-based dehydration procedures to increase the PCC solids content in a PCC slurry or associated with the adding of dry CaCO3 pigment to build slurry solids can be reduced or even eliminated by a facile made in a decanting operation within the inventive process flow.
