Title: Four-wheel steerable vehicle having a fore/aft sliding link
Inventor: ELLINGSEN SVEIN
IPC: B62D7/14
Filed: 1990-03-30
Granted: 1993-06-01
Abstract: FOUR-WHEEL STEERABLE VEHICLE HAVING      A FORE/AFT SLIDING LINK.                 Abstract of the Disclosure A vehicle having four-wheel steering is disclosed. The rotation of the steering wheel is transferred through a steering gear to a double pitman arm.   A drag  link is coupled to one end of the double pitman arm and to the front-wheel steering control arm.   A second drag link is pivotally coupled to the other end of the double pitman arm and to a sliding link.   The sliding link extends from a position adjacent the steering gear to a position adjacent the rear axle.   A drag link is pivotally coupled from the other end of the sliding link to an idler arm.   The idler arm  is  pivotally  coupled  to  the  frame  of  the  vehicle. Another drag link is pivotally coupled to the idler arm and also to the rear-wheel steering control arm.   Rotation of the steering gear causes the double pitman arm to pivot about a central pivot point.   As the double pitman arm pivots, the sliding rod moves axially fore or aft, causing the idler arm adjacent the rear axle to pivot.  As the idler arm pivots, the steering control arm for the rear wheels moves, causing the wheels to turn an amount proportional to the motion of the idler arm.   The support clamp for the sliding link permits fore/aft axial motion of the sliding link but prohibits radial motion of the sliding link.  The length of the drag  links  is variable  to permit precise alignment of the wheels of the front axles with the wheels of the rear axle.

Title: Multi-frequency signal detector and classifier
Inventor: FROESE EDWIN LLOYD
IPC: H04Q1/457
Filed: 1993-04-20
Granted: 1998-05-19
Abstract: A method and  apparatus for detecting and classifying signals that are the additive combination of a few constant-amplitude sinusoidal components, herein called N-tones. The attributes of this method and apparatus include provision of superior classification performance with an algorithm of low computational complexity.   The method includes filtering to remove extraneous signal components, separation of the incoming signal  into one or more output  streams and segmenting and grouping  sets  of  non-overlapping  time-aligned  blocks of successive data samples, or block-sets.   Time-aligned sets of blocks are then obtained by grouping together all blocks with the same demarcation times, thereby selecting one block from each stream.  The following process is applied whenever a new block-set becomes available.  The magnitude of the data within each block of a block-set is estimated along with the frequencies of the dominant spectral components.  The frequency estimates are then used as part of the configuration process of a set of notch filters  for  removal  of  the  identified  dominant  spectral components.  The newly-configured notch filters are then applied to the same data blocks and the magnitudes of their outputs are estimated.  The estimated magnitudes from before and after the notch filtering are then passed on to a block classifier along with  the  aforementioned  frequency  estimates.  This  block classifier tests its inputs to ascertain if the current block-set conforms to prespecified conditions of tonal purity, absolute component magnitude, relative component magnitude and component frequency.  Finally, a timing classifier is applied to monitor the time course of block classifications and test the candidate N-tones for conformance with application-specific requirements regarding signal persistence and longevity.

Abstract: A wideband transim-pedance amplifier utilizing a differential amplifier cir-cuit structure whereby the differential pair is bridged by a signal detector (50 which, as an example, would be a photodetector when the transimpedance amplifier is employed with-in an optical receiver. In or-der to bias the signal detec-tor the differential pair is operated asymmetric with respect to the DC voltage but the circuit maintains a symmetric AC response to the signal detector current input. The circuit is de-signed to operate at the un-ity gain frequency. The sig-nal detector is placed be-tween the source (or emitter) electrodes (32) of the tran-sistors (30) which helps to reduce the impact of gate (or base) capacitance on circuit response speed. These factors combined maximize the bandwidth capa-bilities of circuit. The circuit is responsive to a current input to produce two voltage outputs (15a and 15b) equal in magnitude but opposite in phase.
