  • Method and a system for location estimation using location estimated
    Patent number: 8023961
    Abstract: In a system for location estimation, information necessary for location estimation is acquired from a wireless signal. The first estimated location of each of target terminals is found out on the basis of the acquired information necessary for location estimation, and the locations of reference terminals. The second estimated location of each target terminal is found out on the basis of the information necessary for location estimation, the first estimated locations of the target terminals other than that target terminal of which the location estimation is being carried out, and on the locations of the reference terminals. Thus, the system for location estimation avoids the problem associated with an increased sphere of location estimation and with an increased communication traffic attendant on an increased number of target terminals, and achieves location estimation of high accuracy.

  • Damping mechanism
    Patent number: 8016088
    Abstract: A damping mechanism (1) that generates a damping force in response to a liquid flow between a first liquid chamber (R1) and a second liquid chamber (R2) comprises a partitioning member (2) separating the first liquid chamber (R1) and the second liquid chamber (R2) and a flow passage (P) formed in the partitioning member (2) to connect the first liquid chamber (R1) and the second liquid chamber (R2). The flow passage (P) comprises an odd number of through-holes (10-14) greater than three which penetrate the partitioning member (2) and are connected in series. A large amount of frictional energy loss due to a long path length occurs in the flow passage (P) and causes the damping mechanism (1) to generate a sufficient damping force.
