Inventor: HENNINGE PAUL
IPC: A47D5/00
Filed: 1999-05-06
Abstract: A baby changing station includes a platform coupled by a hinge to a wall structure. The platform is movable between a closed position and an open position. The interlocking configuration of the hinge and the combination of the geometries of the platform, the wall structure and a wall portion result in a baby changing station which is sturdy and is not susceptible to contamination, given the blow-molded parts. The platform is hollow and includes a trough for receiving a baby when in the open position. The wall structure is smaller than the platform in order to be nested within the platform when in the closed position. The blow-molded hinge configuration eliminates the use of a steel pin or rod generally used in the art to strengthen the hinge. The baby changing station of the present invention provides a secure interface which may be easily cleaned and maintained and is less subject to structural damage. The hinge is further provided with at least one stop, and preferably five, which prevent the platform from rotating beyond the open position.

Title: Dispersive electrode skin burns during electrosurgery
Inventor: VILOS GEORGE A
IPC: A61B18/16
Filed: 1999-08-17
Abstract: This invention relates to skin burns at the return electrode site (dispersive electrode, pad electrode, ground pad) that have been experienced during transurethral prostactectomy, Hysteroscopic surgery and other types of electrosurgery even when dispersive electrodes with a Return Electrode Monitoring (REM) system are used. The mechanisms of burn is temperature rising over 45°C at the electrode/skin interface due to excessive current density exceeding the dispersive capacity of pad electrode. In particular this invention is to develop dispersive electrodes with temperatures sensors and alarms, similar to the REM system, warning with flashing lights and/or sound and deactivating the electrical generator (ESU) when the temperature at the electrode/tissue interface rises above 45°C. To avoid or minimize the risks of such an injury the surgeon should consider the following: use the minimum effective power output to vaporize the intended tissue; avoid prolonged activation intervals of the ESU and allow sufficient time between activation periods to dissipate the heat built up at the dispersive electrode/skin interface; consider dispersive electrodes with larger surface area; consider dispersive electrodes with temperature sensors and alarms, similar to the REM system, deactivating the ESU when temperature rises to inappropriate levels; and/or consider bipolar electrosurgical technology, such as coaxial bipolar electrodes (Versapoint TM) that cut, desiccate and vaporize intrauterine lesions in a saline environment.

Abstract: The dynamic mold concept has a manufacture a process and an apparatus. The process is that two or more steps (initial processess) be done simultaneously. A blow molding and an injection molding machine can work within the same mold and do their process together at the same time. The dynamic mold allows the mold to be split up into several parts or it has several dies within the structure. It alows the dies to move to allow the part to exit from the mold and move in accordance to do sevearal steps one after the other also. For manufacturing sake for example shear, thermodynamics temperature demands for quality of product and for reduced mold design cost alow two or more processes be done very close together. The dynamic mold is for metal applications as well incorporating a hydroforming, punch and forging etc. application. The process is open to all known manufacturing processes in metal and in plastic and in ceramics and glass and in pelet form as well most particles for feed limited that the product or process does not have unsafe processes and products. The manufacture are new products applicable to todays products reducing labour and tooling and hence cost. It will help recycling and aid in the enviroment for example more hot and cold bevearge drinking plastic containers will reduce the cost of plastics considerable and reducing the cost of recycling to fewer products to recycle.

Title: Method of altering nutritional components of milk produced by a lactating animal
Inventor: MCGUIRE MARK A
IPC: A23C9/152
Filed: 1998-06-23
Abstract: The present invention alters mammary synthesis of fat to improve milk quality.  These changes in milk composition represent improvements in nutritional quality consistent with contemporary dietary recommendations. Of special importance is the disclosure of new data relating to specific conjugated linoleic acids (CLA), potent naturally occuring anti-carcinogens. In the course of an investigation to enhance milk content of conjugated linoleic acid, it was discovered that abomasal infusion of a single TFA isomer caused a marked milk fat depression. This observation was unexpected because the prior art has consistently shown that body fat and milk fat always show reciprocal changes in lactating cows and indicated that CLA's generally reduced body fat in growing animals. The current disclosure demonstrates that an increase in milk fat content of a specific TFA isomer, trans-10 C18:1.  (Griinari et a1., 1997, 1998) causes MFD. This observation is in conflict with the prior art that taught that an increase in total TFA  caused MFD. These results are applicable to other domestic lactating mammals (e.g., pigs). Upon the infusion of CLA, a portion of the CLA is transferred to the mammary gland and incorporated into milk fat. Hence, the methods disclosed increase the levels of CLA found in milk, thereby improving the nutritional benefits to human health associated with CLA.

Patent CA-2313672-A1 (CA)
Inventor: MCGIBNEY GRANT
IPC: H04L27/26
Filed: 2000-07-07
Abstract: This invention is a wireless network based on orthogonal frequency division multiplexing (OFDM). In a conventional OFDM system, the signal processing hardware is divided equally between the base station and the terminal. In this invention, most of the complex signal processing hardware is shifted to the base station, making the terminal a simpler and more power-efficient device. To send information to the base station, the terminal transmits a series of QPSK symbols that make up an OFDM-code. The code is designed to distribute the signal's energy into a number of OFDM sub-carriers which can be detected and combined within the base station's OFDM receiver. Other users transmit the same OFDM-codes within the same bandwidth and at the same time, but with slightly offset carrier frequencies. Because of the nature of OFDM, the codes from different users remain orthogonal, even in a multipath radio environment. OFDM signals transmitted from the base station are detected at the terminal using a decimator-accumulator structure.
