Title: Enhanced network protocol
Inventor: CARRIER MARC
IPC: H04L29/06
Filed: 1998-08-31
Granted: 2005-11-01
Abstract: A low latency network protocol for use with packet switched data networks is disclosed. In accordance with the protocol, a first computing device (l0a) forms protocol data units ("PDU"s) (50) containing data to be transmitted to a second computing device computing device (10b). Multiple PDUs grouped in sets, each containing identical data are transmitted to the second computing device at short intervals. At least one PDU (50) in each set is transmitted in a packet that conforms to a reliable protocol that requires acknowledgment of receipt of the packet. The remaining PDUs (50) are preferably transmitted in packets that conform to a protocol that does not require acknowledgement of the packets.     Transmission of multiple PDUs (50) containing identical data increases the likelihood that the data will be received with minimal delay. Transmitting at least one PDU (50) using a reliable protocol ensures data will be received. At the second computing device, PDUs (50) containing duplicate data are discarded.

Abstract: A miniature electromagnetic relay is capable of increasing the coil packing density, yet assuring electrical insulation of the coil from a core of the electromagnet. The relay includes a pair of movable and fixed contacts, an armature carrying the movable contact, and an electromagnet block having an excitation coil which moves the armature for closing and opening the contacts upon being energized. The electromagnet block includes a generally U-shaped core with a center core and a pair of yokes extending from opposite ends of the center core, flanges of dielectric material molded respectively around portions of the yokes, and a dielectric tape fitted around the center core over substantially the entire length of the center core to receive therearound the excitation coil in an electrically insulating relation from the core. Each of the flanges is formed integrally with an inward sleeve which extends over a limited length along the center core in such a relation that the dielectric tape overlaps the inward sleeves at opposite width ends of the tape. Thus, the coil can be wound over the substantially full length of the core and be successfully insulated from the core over the full length thereof without requiring additional separate member.
