Abstract: A user interface is implemented using visual indicia and a background for the visual indicia that encodes address information. The background appears visually as a stipple pattern, but is implemented using glyphs which form an address carpet that encodes address information uniquely identifying each location of the user interface. An image capture device is used to capture an area of the address carpet that is at or near visual indicia of interest to the user while selecting a location in the visual indicia. The image capture device captures the area of interest, and transmits the image area to a computer for processing. The computer first determines the proper orientation of the image, and then decodes the information encoded by the glyphs. The decoding results in an X, Y address identifying the location of the captured area in the address carpet and, by reference, the address of the selected location. Based on the address, the computer may perform an operation associated with the area.

Abstract: A camera pen is made from a pen-like housing contains a camera and has a button for sending a signal to a computer which directs the camera to capture an image. The pen-like housing includes landing gear on one end. The landing gear has an opening which forms a flat surface that is angled such that when a user places the camera pen on a surface, the angle at which the pen rests on the surface is ergonomically comfortable for the user. Furthermore, the camera is oriented toward the opening so that when the user presses the button indicating a desire to capture an image, the camera captures the image in the opening. By combining a camera with a pen-like device, the user can comfortably capture image information from a surface.

Abstract: A captured image includes a portion of a set of two-dimensional address codes. The portion of address codes can be decoded to determine a discrete pointer uniquely defining the portion. The captured image is first processed to determine the orientation of the portion, and then decoded based on the orientation to determine the discrete pointer. To determine the orientation of the portion, the portion is first analyzed to determine values at discrete locations within the portion. The values at each location form a matrix of binary data. The values of the matrix are then correlated to determine an orientation of the captured portion of two dimensional address codes. After determining the orientation of the portion, the values can be further analyzed to determine a discrete pointer that identifies the location of the portion within the address space defined by the two-dimensional address codes.

Abstract: A holder having at least one magnetizable body surrounded by a coil is demagnetized by passing through the coil a succession of groups of pulses. The pulses of each group are of the same polarity and the polarity of each group of pulses is opposite that of the preceding group while the current of the pulses of each group is less than that of the pulses of the preceding group. Each group has 2 to 8 identical pulses and the pulses are formed by clipping an incoming alternating-current line voltage.

Abstract: A pump including a first portion (2) with a metering cylinder (3) containing a plunger (4), and a second portion (7) engaging the surface of the first portion (2) in which the outlet of the cylinder (3) is located, and comprising a recess (10) located opposite the cylinder for delivering a liquid. A flexible impervious membrane (8) clamped between the two portions (2, 7) comprises an opening (13) facing the cylinder (3) and a resilient circumferential ring (12) engaging the bottom of the recess (10). A disc (14) in the central area of the recess engages the membrane (8), and a duct (6) linked to the cylinder (5) and having an outlet in the same surface of the first portion (2) as the cylinder (5) is connected to a liquid discharge tubing.

Abstract: A component for a pulp refiner such as a paper pulp refiner. The component comprises an attachment surface (16) for attachment to the refiner, a working surface (17, 22), and at least one core (15, 28, 33, 50, 51) made of rigid material and provided with a wear resistant coating (19, 20, 25) so that at least the useful surface area (18) of the component at least partially consists of the outer surface of the coating (19, 20, 25). Said component is characterised in that said coating (19, 20, 25) consists of a stack of thin layers or strips (21). A refiner including at least one such component, a method for preparing said component and a fiberising and for refining method using at least one such component are also disclosed.

Abstract: A fire curtain has its top fixed to a top framework of a building, the frwork including arrangements for spraying a fluid onto the curtain having two walls fastened together along its bottom and its vertical sides. The fluid spraying arrangements spray at least one interior face of one wall with the fluid.

Abstract: A therapeutic endo-rectal probe comprises at least a piezoelectric transducer element mounted in a support member itself connected to a rigid guide means enabling endo-rectal insertion of said probe, the outside shape of said support member preferably being that of a disk having an outline that is for the most part substantially circular or substantially elliptical, thereby facilitating endo-rectal insertion.

Abstract: A method for obtaining beta casein by separating it from para kappa casein involving the use of rennet casein is disclosed.

Abstract: The invention relates to an implantable blood pump of the type comprising a shell, a closed deformable bag, an inlet valve and an outlet valve, a drum arranged to roll over a wall of the bag, a bracket mounted to rotate about the axis of the drum and connected by an inextensible flexible component to one of the end edges of the bag, and an electric motor integrated inside the drum and suitable for driving the bracket and the drum in mutual and antagonistic rotation over a fraction of a turn to compress the bag which winds onto the drum to expel blood fluid. According to the invention, the outer shell is rigid and constitutes a sealed housing in which the bag can deform, and the bag is made, at least in part, of a material that is inextensible in two directions so that its original volume remains constant, said bag thus being made insensitive to external underpressure tending to increase its volume while blood fluid is being expelled.

Abstract: Inside a flexible shell (10), a deformable pocket (20) is connected to blood circulation via an inlet valve (30) and an outlet valve (40). The pocket is compressed by a floating assembly comprising a drum (50), and a bracket (60) rotatable about the axis thereof. One of the edges (21) of the pocket (20) is fixed to the drum (50); the opposite edge (22) is connected to the bracket (60) by a traction link (70), for example an inextensible sheet. Relative rotation between the drum and the bracket over a fraction of a turn enables the pocket (20) to be wrapped around the drum (50) and the assembly returns to its starting position under the effect of venous pressure. The disposition of the various components provides a self-adapting lever which limits mechanical losses to rolling friction between the drum and the pocket.

Abstract: A resistivity measuring head comprising a body portion and a replaceable nose portion. The body portion contains a plurality of spring-loaded pins located for axial movement in aligned plain openings in a pair of spaced guide plates, and the nose portion contains a number of probes, one for each pin, each precisely mounted in a pair of precisely aligned jewel bearings. The pins bear against one end of the probes for applying an axial working force thereto. Electrical connections are made to the probes either through the intermediacy of the pins or through a plug and socket arrangement wherein the probes are connected to plug pins carried by the nose piece and adapted for engagement with sockets in the body portion.
