Title: Stationary exercise apparatus
Inventor: RODGERS ROBERT E JR
IPC: B62M1/24
Filed: 1996-01-25
Abstract: A stationary exercising device which promotes cardiovascular exercise yet minimizes impact to critical joints. A base frame supports a pair of reciprocating members which are displaced in a horizontal direction parallel with the floor at one end yet reciprocate in a circular motion at the other end through a coupling system attached to the frame. Structure is included which permits each foot of the user to move in a generally elliptical path during the climbing exercise. This provides for more natural movement of the knee and ankle joints minimizing unnecessary stress on the joints yet permitting a cardiovascular workout. The device may include linkage to facilitate a corresponding upper body exercise involving movement of the arm in which case each hand of the user is displaced along an arc or a substantially elliptical path, again promoting a more natural movement of the ankle, knee, elbow and shoulder joints and permitting a cardiovascular workout.

Title: Micro-optic device with means for precisely positioning micro-optic components
Inventor: SEIBOLD GERHARD
IPC: G02B7/00
Filed: 1998-01-12
Abstract: The invention concerns a device whereby micro-optic parts, particularly those that tend to tilt because of their geometric dimensions, can be precisely arranged on a support. The device according to the invention comprises a support(TR) on which several guide elements (FE1...FE4) are placed in cutouts (A1...A4). The arrangement of the guide elements (FE1...FE4) is such that the micro-optic part (BT) to be positioned can be inserted between the guide elements (FE1...FE4). In this way an active adjustment is not required. In a particularlyadvantageous embodiment of the invention, the guide elements (FE1...FE4) touch the micro-optic part (BT) at points that are located at different distances from the surface of the support (TR). In this way tilting is prevented in a particularly effective manner. The support (TR) is made of a silicon substrate for example; the guide elements (FE1...FE4) can be uncoated spherical lenses which are placedin cutouts etched into the substrate by means of wet chemical methods.

Abstract: According to the present invention, a laminar wrapping paper is provided comprising first and second paper layers or laminae.  Each lamina has an inside surface coated with a barrier coating.   The  layers are  laminated by heat lamination,  wherein  the  barrier  coatings  are  melted together, or by providing an adhesive between the coated inside surfaces.  The lamination may be accomplished in a selective or discontinuous manner in order to form air pockets  within  the  laminar structure  to  increase  the insulation  characteristics  of the  wrapping  paper.    A plasticizer is applied to the outside surface of the first lamina.  Graphic designs or lettering may be printed on the outside surface to identify the wrapped product or for purposes of decoration.   The present invention is also directed at a process and apparatus for manufacturing the laminar wrapping paper described herein.  First and second webs of paper are unrolled and passed through coating apparatus to coat one side of each web with a barrier coating.  An adhesive is applied to one of the coated sides of the webs to laminate the webs together, or alternatively heat  lamination  is  performed  using  a  hot  roll.    A plasticizer is then applied to the outer side of the first web.

Title: Angle detection method for bending machine, angle detection apparatus and angle sensor
Inventor: HIRAIZUMI MITSUO
IPC: G01B11/26
Filed: 1997-02-12
Abstract: An angle detection method for a bending machine for detecting the angle of bend of a bent work. Detection light from a light source (9) is projected to a work (W) while an angle sensor (3) is being rotated in both forward and reverse directions, and a plurality of optical sensors (11 and 13) disposed symmetrically with respect to the light source (9) receive reflected light from the work (W). The quantity of light so received is held in correlation with the rotating angle of the angle sensor (3) detected by a rotating angle detector (33), and the angle of the work (W) is calculated by an angle calculation section (35) on the basis of the peak value of the quantity of received light and the rotating angle of the angle sensor (3) corresponding to this peak value. Alternatively, the rotating angle detector (3) detects the rotating angle of the angle sensor (3) when the quantities of received light of a pair of optical sensors (11 and 13) become equal, and the angle calculation section (33) calculates the angle of the work (W) on the basis of this rotating angle. An angle detection apparatus and an angle sensor are also disclosed.

Inventor: PETIT GUIDO HENRI MARGUERITE
IPC: H04L12/54
Filed: 1999-02-04
Abstract: The present invention relates to a method and related devices to be used for cell tagging in a communications network through which cells arranged in frames are transmitted. This communications-network exists of a traffic politer which is coupled to a network buffer. A cell stream is supplied to this traffic politer.      The system determines if the incoming cells are in accordance with the predetermined criteria and tags this cell, if the cell is not in accordance with these criteria. Since in this way only single cells from a frame are tagged, the frame may exist of a mix of tagged and non-tagged cells. Afterwards the distribution of tagged and non-tagged cells is determined, and based on this distribution and some predetermined criteria a decision is made to tag or to set all cells to non-tagged. In this way the frames only exist of tagged cells or non tagged cells. In case of congestion, only entire frames are discarded, not leaving incomplete frames in the network. Network resources consequently are no longer occupied by incomplete frames that are not used.      This cell tagging method and related system avoids incomplete frames in the communications network which are not used in some way by this network, decreasing in this way the network load.
