Abstract: A rolling bearing arrangement for an anti-locking brake system has a pulse ring with projections directed toward the fixed ring. The surfaces of the projections that activate the pulse generator are cut during the hard working of the bearing ring. The pulse generator is integrated in the rolling bearing arrangement. Thereby, on one hand, tolerance limited operational differences in the amplitude and shape of the pulses are avoided, especially during slow rotational speeds of the bearing ring. Furthermore, external influences on the pulse generator and pulse ring caused by rough roads do not occur due to the hermetic encapsulation of the sensitive components.

Abstract: An electrical connection, preferably for ALS sensors incorporated in wheel bearings, is installed coaxially on the wheel bearing and its side surface. It is equipped, for example, with slip rings which operate in conjunction with the electrical contacts of the ALS sensor which is solidly attached to the wheel bearing. This simplifies the manufacture and handling of the wheel bearing during transportation and assembly. In particular, the risk of damage to the connecting cord is reduced during operation.

Abstract: A surgical instrument and method for joining internal body tissue are disclosed. In the preferred embodiment the instrument staples a hernial opening in internal body tissues of a patient comprises an elongate staple cartridge rotatably mounted to an elongate frame at a distal end thereof and an elongate staple forming plate movably mounted to the frame for ejecting a staple from the cartridge into the body tissues of the patient and deforming the staple from an open position to a closed position in which the staple holds together two pieces of body tissue on opposite sides of the hernial opening. The instrument further includes a rotator assembly operatively connected to the cartridge for rotating the cartridge from an orientation aligned with the frame means to a staple ejection orientation transverse to the frame.

Abstract: A permanent magnet structure having at least one loop of circulating flux comprises a first and second plurality of uniformly magnetized prismatic magnetic material sections forming a polygonal shaped cavity and having a point F positioned along a zero equipotential base line joining two vertices within the cavity, that point being the reference for a figure of merit M corresponding to a maximum field strength and a minimum ratio of the value of the area of magnetized material to the area of the cavity. The first plurality of sections totally define the cavity and have their respective remanences aligned to result in a flux passing orthogonally through the base line. The second plurality of section is oriented with respect to their respective remanences and the first sections so as to confine the flux within the cavity. A third plurality of nonmagnetized magnetic sections encloses the base line and borders the first sections for providing an inductive path to channel the flux and close the loop.

Abstract: A rotational phase detecting apparatus for a head drum utilizing a video head capable of directly detecting the rotational phase of the head drum for the reproducing signal of the video head without using an additional pulse generating head by disposing a permanent magnet facing the rotational direction of video heads. When video heads pass by the permanent magnet, positive pulses are generated from the video heads and the positive pulse signal of the first video head is applied to a phase detecting signal processing unit via a rotary transformer and the positive pulse signal of the second video head is converted into a negative pulse signal at the rotary transformer and applied to a phase detecting signal processing unit.

Abstract: A color scan array for linear imaging employing a matrix of photo-sensor and thin-film transistor (TFT) elements aligned in parallel rows with each row representing the same color and sub-pixels of a linear array of pixels. The rows of sub-pixels are sub-divided into groups, with the TFT of each color group commonly connected to a data line, and with plural gate lines provided each connected to the corresponding TFTs of the sub-pixels of each group pixel. The result is a short, compact sensor with a relatively small number of crossings and thus reduced capacitance and increased responsivity.

Abstract: A digitizer tablet capable of reduced coordinate wobble due to beat interference between an induced display scan rate and the tablet scan rate by introducing a controlled delay to change the time between successive samples to increase the beat frequency to the point where it can be effectively filtered out.

Abstract: A digitizer tablet and puck(cursor) for use therewith, characterized that in one aspect the puck is provided with at least one additional control which will provide the user with the ability to control at least one N-dimensional signal in addition to the normal X-Y coordinate data. In accordance with another aspect, any pointing device for the tablet is provided with the capability to control the manner in which the N-dimensional signal varies in response to user manipulation of the pointing device.

Abstract: Stylus for digitizer tablet, with the stylus provided with a finger-actuated side control for controlling the magnitude of a Z-axis signal. The side control remains in the position placed by the user, and preferably comprises a slide switch mounted on the side of the stylus housing.

Abstract: An orthopedic exercise chamber such as a slipper including a light-weight, self-contained limb load monitor is disclosed. The limb load sensor circuit provides extended service life for the miniature power supply that is included in the slipper, thereby making the slipper suitable for out-patient use. A fluid-filled plantar chamber that supports the entire load borne by the patient's foot is connected to the sensor circuit, thereby providing improved monitoring of the load being carried by the leg or foot that must be protected from excessive loading.

Abstract: A mutually and repeatedly reproducible information recording medium, and method for preparing the same, prepared by forming first blocks, adjacent to each other and spaced by space sections, comprising first information on one track of the information recording medium, and forming second blocks comprising second information arranged in the reverse flow direction of information on the other track, so that parts of the other tracks corresponding to the start points of the individual first or second blocks on the one track are always space sections, in which one block of the first or second information is reproduced and, after the reproduction of the block is complete, the information recording medium is run in the reverse direction to reproduce the other track, thereby reproducing the second or first information corresponding to the previously reproduced information.
