Title: Breaker structure
Inventor: YU TSUNG-MOU
Filed: 2005-01-06
Abstract: This invention relates to a kind of breaker device, which primarily comprises a main body, at least two electroconductive plates, an elastic contact plate and a press button. The joint neck of the main body and the accommodation tank body are formed in one block, in which the joint neck is hollow, the connection area between the joint neck and the accommodation tank forms a catch ring with a notch at its inner side edge. The rod body of the press button has a protrusion plate installed at the side and is joined with an elastic piece. When putting together, the rod body of the press button directly penetrates through the joint neck of the main body. The press button is slightly turned with a small angle so that the protrusion plate of the rod body of the press button passes through the notch of the catch ring of the joint neck. The press button is turned reversely with an angle so that the protrusion plate of the rod body of the press button is buckled at the inner side of the catch ring of the joint neck. When there is a current overload and the elastic contact plate jumps, the press button is pushed by the elasticity of the elastic piece but the press button is not going to be disengaged with the joint neck of the main body. This invention utilizes one-block formation of the joint neck of the main body and the accommodation tank of the main body to achieve integral structure simplification, easy assembly and effective cost reduction.

IPC: H03M13/41
Filed: 2005-05-10
Abstract: A system for generating a quality indicator for a trellis decoded signal based on the path metrics of the decoding is presented. An apparatus comprises a path metric processor (105) which determines path metric differences between two path metrics entering a state of a trellis decoder 103. A measured distribution processor (107) orders the path difference metrics to generate a measured distribution. An analysis distribution processor (109) fits a distribution being the sum of a first and second distribution path to the measured distribution. A quality indicator processor (111) determines a quality indicator in response to the fitted distribution. In particular, the first distribution may be associated with correct sign path metric differences and the second distribution may be associated with incorrect sign path metric differences. The quality indicator processor (111) preferably determines the quality indicator in response to only the first distribution thereby reducing the degradation caused by the incorrect sign path metric differences.
