Abstract: A zero insertion force printed circuit board edge connector ensures electrical connection under a worst-case accumulation of mechanical tolerances while precluding the short circuiting of connector contact pins in the absence of a board within the connector by having long contact pins (108) and short contact pins (110), arranged so that the contact regions of the contact pins lie in at leasttwo horizontal planes and no long pin lies opposite nor adjacent to a short pin. When the connector is actuated in the absence of a printed circuit board, the short pins will move underthe opposing long pins butthe pins will not short circuit. During actuation, the pins will move more than half way across the connector opening thereby guaranteeing connection to any card regardless of dimensional tolerance orof card position within the connector opening. A complementary circuit board has correspondingly located pointed contact pads (107) enclosing elliptical areas (201) of high probability of contact of a size based on summing manufacturing tolerances in two orthogonal directions, and permitting intermeshing of the rows on each side of the board to provide denser packing.

Abstract: An acoustic signal processing circuit (12) extracts input speech pattern data and subsidiary feature data from an input speech signal. The input speech pattern data comprise frequency spectra, whereas the subsidiary feature data comprise phoneme and acoustic features. These data are then stored in a data buffer memory (13). The similarity measures between the input speech pattern data stored in the data buffer memory (13) and reference speech pattern data stored in a dictionary memory (16) are computed by a similarity computation circuit (15). When the largest similarity measure exceeds a first threshold value and when the difference between the largest similiarity measure and the second largest measure exceeds a second threshold value, category data of the reference pattern which gives the largest similarity measure is produced by a control circuit (14) to correspond to an input speech. When recognition cannot be performed, the categories of the reference speech patterns which respectively give the largest to mth similiarity measures are respectively compared with the subsidiary feature data. In this manner, subsidiary feature recognition of the input voice is performed by a subsidiary feature recognition section (17).

Abstract: Apparatus for picking up cut crop from the ground or from a mower comprises a rotor 21 driven so that the rotor picks up crop and carries the crop upwardly and rearwardly over the rotor. A hood 54 extends over the front of the rotor 21 and defines therewith a crop flow passage along which the crop is conveyed by the rotor. The hood 54 is pivotally mounted by arms 32 and 33 to side plates 51, and is movable along a predetermined path which is eccentric relative to the axis 65 of the rotor 21. The hood is movable in response to and by the effect of the crop to effect automatic adjustment of the clearance at the entrance to the crop flow passage. An increased crop load moves the hood 54 upwardly and rearwardly against the effect of gravity and optionally against a biasing spring. In other examples, only a front portion of the hood moves, and this may comprise a transverse roller suspended on a hinge above the entrance to the crop flow passage.

Abstract: A highly accurate pressure control system adapted to control fluid pressure in apparatus such as the air pressure in vehicle tires comprises a control module (210) having an air pressure selector (211) for selecting a desired air pressure and a pressure to voltage transducer circuit (230) for generating a signal representative of the actual air pressure. Signals representative of the difference between actual and desired air pressure are applied to comparator circuitry (246, 248) which control output switches (254, 256) for activating an inflate/deflate valve (220) to inflate or deflate the tires so as to achieve and maintain the desired air pressure. Various circuitry of the control module (210) employ reference signals maintained at reference values held constant relative to a common power supply voltage instead of to a ground reference (218), thus minimizing circuit count and power dissipation while providing sufficient current for operating output switches (254, 256).
