The present invention sets forth a methodology for providing improved downlink backhaul services from a radio network controller (RNC) to a plurality of base stations via a backhaul network that provides Ethernet services. The Ethernet services are provided by a group of provider edge (PE) switches and regular label switch routers (referred to as P switches). Base stations within the network are assigned into clusters, each of the clusters having a cluster ID. The RNC transmits packets to a given switch or switches out on the network based on a cluster ID included within the transmitted packet. The communications traffic is then multicast from at least one last hop switch in the network to candidate base stations on the basis of the cluster ID and an active set within the cluster. Advantageously, the clusters act as subgroups for more easily directing the transmission of the backhaul multicast traffic. Significant advantages are realized through use of the present invention, including the ability to allow faster and smoother handoffs, as well as backhaul bandwidth savings since intelligence regarding cell switching is extended out at a point farther along the network than was previously enabled.

A velocity-pressure switching and pressure holding device and system for electrically-operated injection molding machines. The switching between closed-loop position control and closed-loop pressure control of a servo motor of an injection molding machine is quickly and smoothly achieved by a switchable loop switch to ensure the optimal control of the velocity-pressure switching during injection filling and pressure holding. Furthermore an adjustable observation value and a speed reducing set up for the injection axle before switching are provided to allow users to perform minor adjustments on the velocity-pressure switching during the slow down of the injection axle. The present invention easily and precisely achieves the optimal velocity-pressure switching parameters to facilitate better pressure holding ability to increase the quality of the plastic products.

A control device enabling integrated operation of vehicle electric system and engine electric solenoid fuel injection and ignition systems includes a timing circuit for driving a pulse generator to generate a pulse signal. The pulse generated by the pulse generator is limited and then phase-shifted and amplified. The pulse signal for switching operation is then loaded into a positive terminal of a power supply on a motor vehicle by another power device. The control device may further include an automatic distinguishing unit for setting the control device to start and stop working at preset voltages. The transient pulse generated by the control device at engine start enables the spark plug to be instantaneously ignited, and may be stably maintained at a constant transient voltage value to stably supply transient voltage and current to the spark plug and the fuel injector needle valve of the motor vehicle fuel injection system.
