Filed: 1991-10-01
Abstract: A  software  filter  is  described  which  operates  a computer to perform a moving average filter method. The method comprises designating an  initial  filter constant  to  control  the  filter  response  time; maintaining a moving average signal value; finding a difference value between the moving average signal value and each new signal sample amplitude before the new signal sample amplitude is included in the moving average signal value;  updating the running average signal value by adding to it, at a time of each new signal  sample,  a value  calculated by dividing the difference value found for a new signal sample by the initial  filter  constant;  and  when  a  sequential plurality of the found difference values manifest an identical  polarity,  dividing  the  initial  filter constant by an integer  factor to create a reduced filter  constant  which  thereby  reduces  the  filter response time.  When, by contrast, a found difference value  manifests  a  different  polarity   from  an immediately  preceding  found  difference  value,  the filter constant is multiplied by an integer factor to increase its value, not to exceed a maximum value, so as to increase the filter response time.

Title: Method for transmitting data to a plurality of data stations
Inventor: MERTENS KLAUS-DIETER
IPC: H04L12/18
Filed: 1992-04-15
Abstract: ABSTRACT OF THE DISCLOSURE    In a method for transmitting data from a central station to a plurality of data stations via a multipoint connection according to a prescribed transmission protocol, every data station has an address allocated to it under which it receives data and outputs messages to the central station.  When at least two data stations request data from the central station, the central station (z) selects one of the data stations that request data and communicates the address of the selected data station (K1) to the further data station (K2, K3, Kn).  In response thereto, the latter modifies its address to the address of the selected data station (K1).   The central station (Z) transmits data to the selected data station (K1) that is also received by the further data station (K2, K3, Kn), whereby the transmission protocol is only processed between the central station (Z) and the selected data station (K1) during the  data  transmission.    After  the  conclusion  of  the  data transmission, the further data station (K2, K3, Kn) resets its address.

Title: Bearing Assembly for a Downhole Motor
Inventor: WENZEL WILLIAM
IPC: E21B4/00
Filed: 1992-06-18
Abstract: An improvement in a bearing assembly fox a downhole motor consisting of a plurality of notches in one of an exterior surface of an inner mandrel and an interior surface of a housing. The notches are upwardly inclined from a base. A plurality of pins are disposed between the exterior surface of the inner mandrel and the interior surface of the housing. The pins contact the notches such that the pins travel up the incline on the notches upon relative rotation of the housing and the inner mandrel in a first direction and travel down the incline on the notches upon relative rotation of the housing and the inner mandrel in a second direction. The pins become wedged into locking engagement with the notches thereby preventing relative rotation of the inner mandrel and the housing as the inner mandrel rotates in one of the first direction and the second direction.
