Title: Exercise machine
Inventor: HABING THEODORE G
IPC: A63B21/00
Filed: 1994-07-27
Granted: 1998-08-18
Abstract: A multi-station exercise machine has a movable subframe on which a user sits while performing various exercises. The subframe is pivotally attached to a stationery frame and is supported by a lever arm that is also pivotally attached to the stationery frame. The pivot arms coupling the subframe to the stationery frame bear against a carriage that is movable located on the lever arm. A cable and pulley system couples the lever arm to the various operable members of the apparatus so that a selectable ratio of the weight of the subframe, including the user, is communicated as exercise resistence. The amount of weight that is coupled to the operable members is selected by positioning the carriage along the lever arm. This adjustment also varies the height to which the subframe is lifted by the exercise stroke and hence the effort that must be exerted by the user.

Abstract: A method for cascading or linking seismic vibrator sweeps to form a cascaded sweep sequence. According to the method, a first cascaded sweep sequence is generated containing N sweep segments linked end-to-end. The N sweep segments are substantially identical, except that the initial phase angle of each sweep segment within the sweep sequence is progressively rotated by a constant phase increment of about 360/N degrees. A second cascaded sweep sequence is generated consisting of (i) N consecutive sweep segments linked end-to-end which correspond to said first cascaded sweep sequence and (ii) an additional sweep segment linked to the N consecutive sweep segments which is positioned and phased so as to substantially suppress harmonic ghosts during correlation. One of these cascaded sweep sequences is used for the vibrator sweep sequence and the other is used for the correlation reference sequence. Any type of sweeps may be cascaded or linked according to the method, and any amount of padding (listen time) may be inserted between the individual sweep segments.

Title: Billing arrangements for communication call segments having no communications
Inventor: SMITH DAVID B
IPC: H04Q11/04
Filed: 1995-08-21
Granted: 1998-12-15
Abstract: In a telecommunications call a different charge is incurred for intervals of noncommunication than for intervals during which communication may take place. For example, a period of hold is one during which the party on hold cannot communicate with the other end of a connection. Such intervals are accumulated for a call and the charge for the call is adjusted in accordance with the total length of the noncommunicating intervals. Advantageously customers ate charged primarily for the period of time during which they can actually communicate, without having todisconnect and later reestablish a call.
Patent CA-2161048-C (CA)
Title: Prestack seismic migration
Inventor: BANCROFT JOHN C
IPC: G01V1/28
Filed: 1995-10-20
Granted: 1998-08-11
Abstract: A method of prestack time migration based on the principles of prestack Kirchhoff time migration that can be applied to both 2-D and 3-D data.  Common scatter point (CSP) gathers are created as an intermediate step for each output migrated trace. Normal moveout (NMO) and stacking of CSP gathers is performed to complete the prestack migration process.  The method of the present invention allows the CSP gathers to be formed at any arbitrary location for velocity analysis, or to prestack migrate a 2-D line from a 3-D volume. The CSP gather is similar to a CMP gather as both contain offset traces, and both represent a vertical array of scatter points or reflectors.  The CSP gather is formed from all the input traces within the migration aperture.  Samples in the input traces are assigned an equivalent offset for each CSP location, then copied into the appropriate offset bin of the CSP gather in an efficient manner.  The input time samples remains at the same time when copied to the CSP gather.  Data in the CSP gathers may be scaled, filtered, or have noise attenuation processes applied.  The equivalent offset may be derived in a simplified form as a combination NMO and post-stack migration or in a more complex form based on the double square root (DSR) equation of prestack migration.  The prestack migration form of the CSP gather enables it to correctly image scattered and dipping events prior to NMO.  The prestack nature, high fold, and large offsets aid in providing a better focus of the semblance plot for an improved velocity analysis.

Title: Method and apparatus for rms current approximation
Inventor: PHILLIPS TIMOTHY BRIAN
IPC: G01R19/02
Filed: 1994-08-03
Granted: 1998-06-16
Abstract: A method and apparatus provides for a measurement technique which approximates the true rms value of a current waveform. The technique involves converting the current waveform to a voltage by rectification and determining the peak value and the average value of the resultant voltage. A summing circuit (42) combines the two values at a predetermined ratio to create a DC voltage that is approximately equal to the rms value of the input currents. The DC voltage output is suitable for a wide range of applications. A combination of the approximation circuit (32) with a time integrating circuit (44) and a level detecting circuit (46) produces a low cost solid state overload relay in a preferred embodiment of the invention. Other uses include metering and use as a current feedback control signal for controlling PWM inverters and the like.

Abstract: A tow-behind implement and a hitch therefor are provided. The hitch is for securing the implement to a pulling vehicle such as a tractor. The hitch attaches a farm or industrial implement to the drawbar of a pulling vehicle. The hitch mechanism includes a clevis swingingly and rotatably mounted to an offset hitch component which is secured to the tongue or the like of the pull-behind implement. This swinging attachment is at a location forward of the hitch pin. The clevis remains parallel to the drawbar regardless of the attitude of the implement in order to increase contact surface area. In addition, the weight of the implement is ahead of the hitch pin in order to reduce stress on the drawbar. Angular movement which is provided by the hitch is greater than that provided by standard implement hitch devices.
