Patent CA-2089662-A1 (CA)
Inventor: BELIVEAU YVAN J
IPC: G01C3/06
Filed: 1991-08-19
Abstract: A spatial positioning apparatus providing three-dimensional position information and methods to utilize the position information for improved surveying, construction layout, equipment operations, manufacturing control and autonomous vehicle control is disclosed. The spatial positioning apparatus includes at least three, preferably four, fixed referent stations (210). A minimum of two, preferably three, of the fixed stations sweeps a spread laser beam horizontally across the site of interest (Fig. 1B). The remaining fixed stations sweeps a spread beam vertically across the site of interest (Fig. 2). A strobe signal is emitted from each fixed station when the rotation mechanism actuates a rotation datum (230 or 234). The spatial positioning apparatus also includes one or more portable position sensors (240). The portable position sensor includes a light sensitive detector (242), a computer (246), and a display (254). The x, y, z coordinates of the portable position sensor are obtained through a triangulation technique based on time marks received from each spread laser beam from the fixed stations and the rotation datum received from the strobe of each fixed station. Alternatively, the system may include counter-rotating lasers (Fig. 17) and/or an ''axicon''-type detector (Fig. 25). Multiple portable position sensors for use in attitude information for productivity improvement for equipment and for control of autonomous vehicles are disclosed.

Title: Process and apparatus for vertical continuous casting of metal
Inventor: SCHNEIDER WOLFGANG
IPC: B22D11/16
Filed: 1993-03-03
Abstract: Abstract of the Disclosure Process and apparatus for vertical continuous casting of metal in at lest one hot-top mold with metal supplied at constant level.  The object of the invention is to provide a process and an apparatus that make it possible, while supplying metal at constant level, to avoid non-uniform temperature gradients,  turbulence,  and waste of metal. According to the invention this is achieved by coordinating the level, flow rate and distribution of molten metal to each hot-top mold from the outlet opening of a smelting furnace.  This is produced by a pouring spout or trough that is supported through the upper wall area of each hot-top mold to supply molten metal to each hot-top mold through central outlet openings in the side walls of the trough, with the bottom of the trough being in a plane below the level of the outlet opening of the smelting furnace and below the upper surface of the melt in the hot-top mold, and with the trough outlet openings supplying molten metal to the center of each mold and causing it to flow outwardly therefrom.

IPC: G06K9/00
Filed: 1991-10-23
Abstract: An array of electrodes is applied to an internal or ex-ternal surface of a biological system such as a human being.    The electrodes generate signals which are processed to com-pure a surface differential of the surface potential at a multi-plicity of spatial locations within a given time epoch. The sig-nal processing is repeated for multiple sequential time epochs and an image is constructed from the surface differential of the surface potential for each time epoch. Thereafter, the se-querttial images corresponding to sequential time epochs-are displayed: The two-dimensional image changes as the distrib-ution of bioelectric sources evolves so as to provide a motion picture of electrical activity.

Title: Data transmission system with packets having occupied, idle, released, and reset states
Inventor: TANAKA TSUTOMU
IPC: H04L12/56
Filed: 1993-08-16
Abstract: ABSTRACT    Disclosed is a data transmission unit for use in a system wherein data to be transmitted is organized into packets which may be assigned one of four states: idle, occupied, released, or reset. Or these packets may be assigned one of three states: idle, occupied, or released, each state being able to include a reset bit.   Each unit has terminals associated therewith and is assigned two windows on the number of packets it may transmit.  One window is a parameter for transmitting data by using idle packets and the other is by using released packets.  The unit responds to the state of a received packet, the state of the windows,  and the presence or absence of transmit data to control whether the packet transmitted out of the unit is a packet from internal transforming buffers, a released packet from a released cell producing circuit,  an occupied packet containing data from the unit's own terminals.        A released packet contains the address of  the unit which generated it and is generated when there is no data to be transmitted and an idle packet is received by the unit.  Any unit can occupy a released packet with data from its terminal within  the  second  window  band,  thereby  increasing  data throughput.

Title: Yolk sac stem cells
Inventor: WAGNER THOMAS E
IPC: A61K35/54
Filed: 1992-07-14
Abstract: The present invention is directed to yolk sac stem cells. In particular, it relates to the characterization, culturing, and uses of yolk sac stem cells for hematopoietic reconstitution and therapy. Yolk sac stem cells isolated from the early embryonic yolk sac prior to blood island formation exhibit a homogeneous morphology and primitive cell surface phenotype without the expression of mature leukocyte markers and major histocompatibility complex encoded antigens. The cells can be cultured and expanded long-term without alteration of their pluripotency. Therefore, yolk sac stem cells may have a wide range of applications including but not limited to the reconstitution of a destroyed or deficient human hematopoietic system, and the construction of large and small animal models for the production of human blood cells, human antibodies, and testing of human diseases, immune function, vaccines, drugs and immunotherapy.
