Abstract: A rocker arm assembly including a rocker body having an upper wall arranged above a pivot axis, two ears extending from opposing sides of the upper wall and defining a pivot bore coaxial with the pivot axis, and a pad end wall and a socket end wall each extending from the upper wall and the ears. A pad having a convex pad surface is formed on the pad end wall for engaging a valve and a socket having a concave socket surface is formed on the socket end wall for engaging a pushrod. The rocker arm assembly further includes a trunnion body and a bearing, each disposed in the pivot bores and for facilitating pivoting movement between the rocker body and the trunnion body.

Abstract: A speech compressor utilizing Trellis Encoding and Linear Prediction (TELP). A TELP speech compressor provides improved signal generation and search technique for a code-excited linear prediction (CELP) speech encoder. TELP is a frame oriented coding that breaks the quantized speech signals into frames of prescribed length N and each frame into subframes of prescribed length L, which are processed as dependent units utilizing an analysis-by-synthesis approach. The approach is based on constructing the best mean square linear predicting filter and searching the best exciting sequence for the filter in order to produce synthesized speech. A trellis encoder is used instead of a stochastic code book. The Q-ary analysis of a given subframe and previous excitations is proposed for a fast vector search in an adaptive code book. It simplifies the implementation of digital speech compression.
