    Abstract: A modem system utilizes PCM encoding and transmission techniques in the upstream direction from a client modem (connected to a digital network via an analog loop) to a central site modem (connected to the digital network via a digital link). The modem system employs precoding techniques that enable the transmit signal to be pre-equalized to compensate for the analog channel characteristics. The precoding technique generates a plurality of equivalent signal point sequences in response to a digital data input. The signal point sequences are analyzed and compared relative to a predetermined cost metric such as transmit power. A preferred signal point sequence is selected and transmitted to the central site modem.

    Abstract: A pulse code modulation (PCM) modem system employs a relatively white training signal to optimize the adaptive filter coefficients in the receiver equalizers. During the training mode, any line coding or equivalent spectral shaping is disabled to provide a training signal sequence having a substantially even spectral content. The presence of DC within the training signal reduces the likelihood that the error function of the equalizers will settle at a local minimum. Following the training interval, the encoder enables the line coder to condition the digital input sequences, introduce DC nulls, and reduce the detrimental effects of baseline wander.

    Abstract: A method and equipment for mixing hard granules into tire tread bodies and into sundry rubber strips and tread stock. Rubber stock is extruded into tread bands of a suitable shape which are rolled under control, in a suitable thickness and number of layers, in a circular process over a pre-treated tire, or other object. The tire is subsequently patterned and vulcanized. The hard granules are distributed according to a predetermined configuration onto at least part of the surface of the extruded rubber tread band before the next layer is rolled in a circular process onto the pre-treated tire, using dedicated equipment so that the granules will be mixed into the patterned wearing surface of the tire after profiling and vulcanization.
