Title: A method of correcting the position of a track
Inventor: THEURER JOSEF
IPC: E01B35/00
Filed: 1999-01-18
Abstract: In a method of correcting the position of a track (2) which is composed of laterally adjacent track sections (3,4) connected by a branch track (5), the track sections are respectively surveyed by means of an absolute reference system (17) common to both sections, whereby actual position curves are formed and the high points thereof are registered. ~A common desired position curve is then created for the surveyed track sections by connecting the said high points by design sections smoothening the trace of the curve. By forming the difference between desired- and actual position curves, track correction values are determined, according to which the track position correction is implemented while synchronously lifting or laterally displacing the two track sections.

Abstract: A power take-off unit includes a hollow housing having an input shaft, an idler shaft, and an output shaft supported therein. The input shaft is supported on the housing and carries an input gear thereon that is adapted to be rotatably driven by an engine, transmission, or other source of rotational energy. The idler shaft is supported on the housing and carries an idler gear thereon that meshes with the input gear so as to be rotatably driven thereby. A first end of the output shaft is supported on an inwardly recessed side wall formed integrally with the housing. A second end of the output shaft is supported on a bearing cap secured about an opening formed through a second side wall of the housing. A clutch assembly may be provided for selectively connecting the idler gear to the output shaft. A mounting flange is formed integrally with the housing about the inwardly recessed side wall and is adapted to facilitate the attachment of the driven accessory directly thereto. The mounting flange may include a flat mounting surface having a pair of apertures formed therethrough. The mounting flange may further include an annular stepped recess extending formed through the inwardly recessed side wall of the housing that functions as a pilot opening to facilitate the mounting of the driven accessory on the housing of the power take-off unit and to insure that the input shaft of the driven accessory is co-axial with the output shaft of the power take-off unit. The housing of the power take-off unit significantly reduces the amount of physical space occupied by the power take-off unit and the driven accessory, and further enhances the flexibility of positioning the driven accessory relative to the power take-off unit.

Inventor: CIOFFI JOHN M
IPC: H04B7/04
Filed: 1997-08-29
Abstract: In a system and method of digital wireless communication between a base station (B) and a subscriber unit (S), a spatial channel characterized by a channel matrix H couples an adaptive array of Mt antenna elements (1-Mt) at the base station (B) with an adaptive array Mr antenna elements (1-Mr) at the subscriber unit (S). The method comprises the step of determining from the channel matrix H a number L of independent spatio-temporal subchannels, and encoding a plurality of information signals into a sequence of transmitted signal vectors. The transmitted signal vectors have Mt complex valued components and are selected to transmit distinct signal information in parallel over the independent subchannels, thereby providing increased communication capacity between the base and the subscriber. The sequence of transmitted signal vectors is transmitted from the base station array (1-Mt), and a sequence of received signal vectors is received at the subscriber array (1-Mr) and are decoded to yield the original information signals. Specific spatio-temporal coding techniques are described that increase system performance.

Title: Method for wireless communication transfer with an implanted medical device
Inventor: KOSLAR MANFRED
IPC: A61N1/372
Filed: 1997-11-03
Abstract: A method of wireless communication with a medical device, especially one implanted in the human body. A message input signal (S1, g4) undergoes angular modulation in a transmitter (2 - 8, 16 - 26) and reaches a receiver via a transmission channel (11-15,16 - 26). The transmitter produces angularly modulated pulses having a frequency spectrum and carrying information, in such a way that said pulses can be time-compressed in the transmitter by means of a filter (13) with a frequency dependent transit time, especially a dispersion filter (13,32, 33) so that pulses with reduced duration and higher amplitude can arise, and at least one pan of the information that makes up the message is impressed after a further modulation or message technology coding process and is subsequently received and/or at least one part of the information that makes up the message is impressed in addition to the angular modulation.

Abstract: A user interface for use on the computer of a biomedical analyzer system having at least one biomedical analyzer instrument. The user interface inputs work orders, including sample and test id's, and transmits them to the instrument. The instrument performs the requested tests and sends the results to the computer, where they are stored.  The test results are compared to exception review criteria to identify exception test results for operator review. Exception test results are indicated by a graphic icon on the display of the computer. The exception test results are compared by an operator to validation data gathered from the instrument and stored in the computer. The operator may then select a disposition for the exception test results. Alarm conditions are communicated by the instrument to the computer and the user interface communicates the alarm conditions to an operator by using a graphic image of the instrument and an affected part.

Title: Conductivity anisotropy estimation method for inversion processing of measurements made by a transverse electromagnetic induction logging instrument
Inventor: FANINI OTTO N
IPC: E21B41/00
Filed: 1999-07-06
Abstract: A method for generating an improved estimate of horizontal conductivity, dip angle, azimuth and anisotropy parameter of an earth formation penetrated by a wellbore from dual-frequency transverse electromagnetic induction measurements, comprising generating an initial estimate of the horizontal conductivity, dip angle, azimuth and anisotropy parameter from the dual-frequency transverse induction measurements made at each one of a plurality of base frequencies. The initial estimates from each of the plurality of base frequencies are input into a primary trained neural network, and the improved estimate is calculated by the trained neural network. The network is trained by generating models of earth formations each having a known value of horizontal conductivity, anisotropy parameter, dip angle and azimuth. Voltages which would be measured by the transverse electromagnetic induction instrument in response to each model are synthesized. Initial estimates from the synthesized voltages are calculated and the initial estimates and known values from each of the models are input to the neural network to cause it to learn a relationship between the initial estimates and the known values.

Abstract: An arc jet CVD system includes a plurality of plasma jet distribution heads. The distribution heads are preferably linearly arranged, preferably angled relative to a line normal to the substrate surface on which a diamond film is being coated, and preferably spaced relatively apart with respect to a defined profile width. In addition, the plasma jets are preferably configured in accord with a defined parameter which is a function the reagent gas flow and viscosity, the distance between the distribution heads and the substrate, and the area on the substrate exposed to the gas from a distribution head.      Configuring the plasma in accordance with the defined parameter-ensures an acceptable minimum level of efficiency with respect to hydrogen reagent use, and further provides a relatively uniform diamond film coating on a substrate. It is also preferable that the plurality of jets and substrate are preferably moved relative to one another during diamond film deposition for increased uniformity. The combination of the relative arrangement of the distribution heads, the configuration with respect to the defined parameter, the angling of the distribution heads, and the relative movement between the distribution heads and the substrate provide an efficiently operable system for manufacturing substantially uniform thickness diamond film.
