Title: Vehicle position determining apparatus
Inventor: ALOFS CORNELL W
IPC: G05D1/02
Filed: 1995-03-24
Granted: 1998-07-14
Abstract: Apparatus for determining the position of a mobile vehicle relative to a fixed location marker device which comprises a coil energized to emit a magnetic field composed of lines of magnetic flux extending radially and arcuately from the ends of the coil's longitudinal axis.  A sensor unit mounted on the mobile vehicle comprises four identical sensing coils each responsive to the frequency of the magnetic field of the marker device and each having a major axis. These sensor coils are supported in two pairs with the major axes of the sensor coils of each pair disposed on either side of a common central plane and extending parallel   thereto,   this   common  central   plane   extending transversely to the longitudinal axis of the marker device coil.          Each pair of sensor coils is arranged in an X pattern in which their major axes cross each other medially and perpendicularly to define a center for the coil pair.  The two pairs of coils are mounted with their centers spaced apart a fixed distance on a base line which the major axes of the coils cross at a 45 degree angle.  Position signals from the sensor coils are processed to produce  X  and  Y  coordinate  values  indicating  the  relative position of the sensor unit to the marker device.   The marker device may be inductively excited from an antenna on the mobile vehicle.

Abstract: Steel alloys containing chromium may be hot dip aluminized in a bath having up to 15% silicon with improved wettability by using a bright prennealing practice in a box furnace having a substantially pure hydrogen atmosphere. The surfaces of the preannealed steel are easily coated if the box annealing furnace has a dew point of less than -60°C (-75°F). The preannealing should also include a minimum soak of at least 1 hour at a temperature of 675°C to 785°C (1250°F to 1450°F). It is important that the surfaces of the strip after preannealing are not removed prior to aluminizing. During the aluminizing operation, the strip temperature does not need to be heated to much above the bath temperature since the strip has already been preannealed. The furnace is maintained to avoid oxidation with an atmosphere which is typically a nitrogen, hydrogen or a hydrogen-nitrogen mixture. The surfaces of the steel prior to entering the aluminum bath have improved wettability and result in far less uncoated spots due to the improved surfaces provided by the preanneal in the dry box anneal. For ferritic stainless steels, such as Type 409, the surfaces have an iron enriched layer.

Title: Method of and apparatus for signal recognition that compensates for mismatching
Inventor: LEE CHIN-HUI
IPC: G10L15/02
Filed: 1995-04-25
Granted: 2000-06-13
Abstract: Disclosed is a method for drastically reducing the average error rate for signals under mismatched conditions. The method takes a signal (e.g, speech signal) and a set of stored representations (e.g, stored representations of keyword) and performs at least one transformation that results in the signal more closely emulating the stored representations. This is accomplished by using one of three techniques.  First, one may transform the signal so that the signal may be better approximated by (e.g, is closer to) one of the stored representations.  Second, one may transform the set of stored representations so that one of the stored representations better approximates the signal. Third, one may transform both the signal and the set of stored representations.

Abstract: An optical device having a switching function has a waveguide filter for switching an input signal light including at least one specific wavelength to be either transmitted or reflected. The input signal lights of wavelengths .lambda.1 to .lambda.n are transmitted to the input waveguide. When the waveguide filter is off, the signal lights of all wavelengths are transmitted to the output port. when the waveguide filter is on, the signal lights of wavelengths .lambda.2 to .lambda.n are transmitted, but the signal light of wavelength .lambda.1 is reversed and output to the drop port. If the thin film heaters are off, a signal light of wavelength .lambda.1 is output (dropped) from the drop port. If the thin film heaters are on, it is reversed and transmitted to the output port.
