Title: Method of investigating the gait of a living being
Inventor: ROOST WALTER
IPC: G01L1/26
Filed: 1990-03-05
Abstract: ABSTRACT      The force exerted on a measuring section is broken down into two components each acting on one end of a measuring section.     The components are each broken down into a vertical part and a horizontal part. The two vertical parts obtained are measured separately. The measured values are cyclically in-terrogated in an interrogation sequence in the direction of movement of the living being and stored, to permit the deter-mination of force, location, duration and course in time.     The measuring surface is subdivided lamellar-fashion at right angles to the direction of movement. One measuring sec-tion is narrower than the foot and longer than the track width. The force sensing device (3) comprises a rigid cross-beam which is borne on a sensing block (7) on both sides and acts in the vertical direction on a measured value delivering sensor (23) disposed therein.     The crossbeam is mounted to move only vertically and borne on a measuring spring (43) which bears against the sensing block (7) and is preferably a flat spring. The meas-ured value delivering sensor (23) measures the vertical move-ment of the measuring spring (43).     A transmission element (47) is disposed between the measuring spring (43) and the measured value delivering sen-sor (23) and is acted upon in the direction of the measuring spring (43).

Title: Wideband digital equalizers for subscriber loops
Inventor: CRESPO PEDRO M
IPC: H03H15/00
Filed: 1990-08-13
Abstract: A digital decision feedback equalizer is disclosed in which compensation for the post-cursors of the impulse response of the transmission channel is divided up into two regions. A first region encompasses the initial rapidly changing unpredictable transient response, possibly oscillatory, of the transmission channel. A fast acting, close-tracking linear filter is used to compensate for this largely unpredictable initial transient. The second region of the impulse response is the slowly changing, easily predictable asymptotic tail of the impulse response. This second region can be compensated for by a relatively slowacting, simple pole-zero filter. Together, the two equalizer sections provide anoverall equalizer design far less complicated and less expensive than an equalizer based on a single linear compensating filter. A finite impulse response (FIR) filter is used to compensate for the unpredictable, rapidly changing initial transient portion of the impulse response, while an infinite impulse response (IIR) filter is used to compensate for the slower acting tail portion of the impulse response.

Abstract: ABSTRACT OF THE DISCLOSURE            The  Hot-Weak-Rock  Process  overcomes  the mechnical limitation inherent to the Hot-Dry-Rock Process,  of not being able to overcome the shear strength of the rock beyond a certain depth in order to create heating surfaces through Hydro-Frac.  The Hot-Weak-Rock Process develops a heating zone in an area of the continental lithosphere in which the shear strength of the hot rock suddenly decreases with increasing overburden and the Hydro-Frac necessary to create  heating  surfaces  is  effectuated  under  the hydrostatic pressure of a water column in a correspondingly deep and lined boring.   A technically easily generated additional pressure component  is  applied to the water column in the boring to create the initial cracks in the lower, unlined section of the boring.
