Patent DE-3482081-D1 (DE)
IPC: H01R12/58
Filed: 1984-07-30
Granted: 1990-05-31
Abstract: A compliant, press fit, electrical contact includes a relief groove which forms an area of reduced cross sectional thickness to provide a stress concentration, and thus a controlled region of plastic flow, to create a plastic-elastic hinge. When the contact is inserted into a plated through hole in a printed circuit board, the hinge elastically deforms until a predetermined push-in force is reached, at which time a controlled plastic flow begins. Once the point of plastic flow is reached, the amount of additional push in force required for additional deflection of the hinge is greatly reduced, so that smaller hole sizes may be accommodated with a relatively small additional push in force. However, the required minimum pull out force is maintained for the entire range of hole sizes, since elastic energy remains stored in the hinge, even after plastic flow begins. The contact is manufactured through a series of simple coining and punching operations, so that complex rounding and rolling operations are avoided.

Granted: 1991-04-18
Abstract: On pattern matching an input pattern arranged along a first time axis to each concatenation of patterns selected from reference patterns and arranged along a second time axis with feature vectors of the input pattern and the concatenation placed at a common frame period, a dynamic programming algorithm is used by classifying the reference patterns into classes in compliance with reference pattern lengths and by giving variable block widths to slant parallelogrammic blocks of a common block slope. The variable widths should be decided for the respective classes. Preferably, a k-th class comprises a reference pattern of a reference pattern length which is not shorter than  beta kW and is shorter then  beta (k+1)W, where  beta represents the block slope and W, a fundamental block width determined by the block slope under a minimum of the reference pattern lengths. In this event, the variable block width is equal to kW. The algorithm is carried out by scaling the first time axis, not by the frame period, but by block numbers assigned to slant parallelogrammic blocks having the fundamental width in common and by checking whether or not each block number is an integral multiple of k.
