Patent KR-20020015035-A (KR)
IPC: B61B10/02
Filed: 2000-04-05
Abstract: A shock absorber trolley has a trolley frame including trolley wheels (7), a rearward cam, and a shock absorbing mechanism linked to the rearward cam. The trolley is especially adapted for use in a trolley assembly employed for bias banking of assembly (10) loads (13). The shock absorbing mechanism decelerates an adjacent trolley assembly during accumulation by absorbing impact energy when the leading trolley (1) of the adjacent trolley assembly strikes the rearward cam of the shock absorber trolley. When employed as an intermediate trolley (3) in a trolley assembly, the absorption of energy minimizes both noise generation and swaying of the assembly load during the biased banking of loads.

Title: Method for implementation procedure in giga bit ethernet passive optical network and ethernet frame structure thereof
Inventor: CHOI DO IN
IPC: H04Q11/00
Filed: 2002-01-17
Abstract: PURPOSE: An operation implementing method in a GE-PON(Giga-bit Ethernet-Passive Optical Network) system and its Ethernet frame structure are provided to implement a frame format structure for effectively receive a giga-bit Ethernet traffic and a procedure for initial and periodical ONU(Optical Network Unit) registration, ranging and dynamic allocation of band. CONSTITUTION: An OLT(Optical Line Termination) periodically transmits synchronous signal to plural ONUs(22i,22j). The ONUs(22i,22j) are synchronized with the OLT(20). ONUs(22i,22j) waits for a grant frame coming down at first of every period. ONUs(22i,22j) check whether a value of a grant type field of the grant frame is set to an initial registration. If so, the ONUs(22i,22j) recognize ONU upstream data transmission state point and transmission time length. In order to avoid, the ONUs(22i,22j) transmit a registration request frame as an initial registration request frame to the OLT(20). The OLT(20) calculates an RTT(Round Trip Time) by using a difference between an initial registration request frame upstream transmission time estimate arrival time and an actual arrival time and a random delay value. The OLT(20) registers the ONUs(22i,22j) and assigns a new ONU ID to the ONUs(22i,22j). The OLT(20) transmits a registration response frame including the newly assigned ONU ID and the round trip type RTT to a corresponding ONU.
