A network switch includes network switch ports, each including a port filter configured for detecting user-selected attributes from a received layer 2 frame. Each port filter, upon detecting a user-selected attribute in a received layer 2 frame, sends a signal to a switching module indicating the determined presence of the user-selected attribute, for example whether the data packet has a prescribed priority value. The network switch includes a flow control module that determines which of the network switch ports should output a flow control frame based on the determined depletion of network switch resources and based on the corresponding priority value of the network traffic on each network switch port. Hence, any network switch port that receives high priority traffic does not output a flow control frame to the corresponding network station, enabling that network station to continue transmission of the high priority traffic. In most cases, the congestion and depletion of network switch resources can be alleviated by sending flow control frames on only those network switch ports that receive lower priority traffic, enabling the network switch to reduce congestion without interfering with high priority traffic.

A digital based two wire proximity transmitter system and a method for calibrating the system, wherein the transmitter includes a customized linearization table uniquely generated during calibration to take into account the unique impedance properties of a particular probe / coaxial cable configuration. During calibration, the probe is positioned adjacent a calibration target. The calibration target is selected to have the same material characteristics as the target to be monitored during actual operation of the transmitter in the field. At a fixed distance between the probe and calibration target, the resonant frequency of the probe / cable system is determined. Thereafter, utilizing this resonant frequency to excite the probe, the voltage response of the probe / cable system is determined as the distance between the probe and the target material is incrementally changed. The voltage output is used to build a table for incremental distances, wherein each distance is characterized by a non-linear output that has been equated to a linear output. This uniquely generated table is subsequently downloaded into the transmitter for reference during monitoring.

A hybrid electronic control unit sends a combustion start command to an engine ECU when the rotation speed of an engine reaches a combustion start rotation speed by engine cranking. The engine ECU sends an initial explosion advance notification to the hybrid electronic control unit when the crank position of the engine reaches a specific position prior to an ignition timing of an initial explosion cylinder by a preset crank angle θec. Ignition of the initial explosion cylinder is performed at a timing when the crank position is further rotated by the preset crank angle θec. The hybrid electronic control unit sends a torque command in view of a counter torque Tα to a motor ECU after elapse of a preset time period tv. The preset time period tv is the sum of a first time period t1 between reception of the initial explosion advance notification and the ignition timing of the initial explosion cylinder in the engine and a second time period t2 between the ignition timing of the initial explosion cylinder in the engine and appearance of torque effect caused by the ignition of the initial explosion cylinder on a driveshaft. Such control timely reduces the torque effect caused by the initial explosion of the engine on the driveshaft.
