Inventor: JETTE GAETAN
IPC: E01F9/00
Filed: 2002-03-27
Abstract: Safety system for entering and exiting garage doors and entrances comprises a warning sign adapted to be placed by an attachment means at a primary line of sight of a driver of a truck during lowering and raising movement of the door. A delay means are provided to facilitate a movement of the sign in such manner that the sign will always appear first in the primary line of sight of the driver to eliminate a possibility of collision between the truck and the door. A moving means are adapted to lower the sign into an operational position and provided to keep the sign in non-operational retracted position when the door is completely open to ensure clearance for moving track. Warning sign is activated by a warning sign activating means such as a motor-driven assembly. The door is activated by a detector adapted to transmit signal to a door control panel operating the movement of the door by a door motor.

Title: A package of strand and a method and apparatus for manufacturing the same
Inventor: FAZIO MICHAEL B
IPC: C03B37/03
Filed: 2001-02-28
Abstract: A self-supporting package of strand is disclosed. The disclosed method of manufacturing a package of strand (40) is directed to the bulk collection of the strand. The disclosed strand collection system includes an attenuator (100) that attenuates filaments (20) from a bushing. The attenuator includes a pair of belts (112, 132) between which the strand is pinched to pull the filaments from the bushing. The attenuator directs the strand to a deflector assembly (200) that slows down and imparts a degree of movement to the strand.  The deflector assembly includes primary and secondary deflector surfaces (222, 214) which the strand engages. After the strand deflects off the secondary deflector surface, it is directed into a container assembly (300). The attenuator and deflector assembly traverse above the container assembly to deposit the strand. The container assembly is periodically vibrated by a vibrating mechanism (400) as it collects strand. The vibrations settle and shift the strand in the container assembly for better strand distribution. The container assembly includes an outer container (310) with perforations (336) through which air and water can flow to remove moisture from the package. The container assembly also includes an inner container (370) that provides support during the shipping of the package after the outer container is removed. After the strand has filled the container assembly, the container assembly and strand is dielectrically dried. The package (500) may include intra-package splices (698) of the strand if the strand breaks during the collection process. The strand collection system couples filaments or strands together to reduce or eliminate slippage of the strands when they are pulled from the package. The links are referred to as authentic links. When the strands have been coupled, the strands are easily and accurately run out of the package.

Abstract: One or more templates (20a-20c) are provided for circulating fluids in a main wellbore (92) and for drilling and completing at least one offset wellbore (160, 164) from the main wellbore. Each template has a body (21), an inlet leg (22), a main outlet leg (23), and an offset outlet leg (24). A straddle assembly (60) is mounted in the template to configure the tem-plate for fluid circulation. The straddle assembly, in coopera-tion with the inlet and main outlet legs, effects a downhole flow path which directs fluids from the inlet leg through body of the template and out the main outlet leg, bypassing the offset outlet leg. The straddle assembly is distally displaced from the tem-plate to reconfigure the template for drilling. A diverter (140) is placed in the body of the template upon displacement of the straddle assembly to define a drill string path from the inlet leg to the offset outlet leg.

Title: Method and device for the noninvasive determination of hemoglobin and hematocrit
Inventor: WU XIAOMAO
IPC: A61B5/1455
Filed: 2001-05-07
Abstract: A method for the determination of hemoglobin and hematocrit by means of an apparatus that is capable of controlling the temperature of a defined subcutaneous volume of human skin. The method involves a calculation of hemoglobin concentration and hematocrit value that takes into consideration the values of optical parameters of the sample at various pre-set temperatures. It employs steady state optical measurements of samples, such as, for example, human tissue, by means of a reflectance tissue photometer and localized control of the temperature of the sample. An optical signal from a defined subcutaneous volume of human skin is measured as the temperature of this volume is controlled. This allows determination of hemoglobin concentration and hematocrit value non-invasively in a population of subjects having different skin colors by means of steady state reflectance measurements. The determination of hemoglobin concentration and hematocrit value is useful for monitoring patients, testing at the point of care, and screening for anemia. This method has the advantage for the determination of analytes in weak cardiac pulse situations, such as, for example, in elderly patients.
