  • Publication number: 20140228141
    Abstract: A swing analyzer is disclosed. The swing analyzer may be used to analyze the swing an object such as a golf club. The swing analyzer accounts for individual differences between users and/or sensors to improve performance. The swing analyzer includes a motion sensor that is attachable to the object. The motion sensor communicates wirelessly with a terminal device. The terminal device includes a swing analysis unit for performing swing analysis based on sensor data output from the motion sensor. The swing analyzer determines a target line based on position of the motion sensor while a user is at the address posture before a swing. The target line is used as a reference to provide swing analyses.

  • Patent number: 6118759
    Abstract: A network system in which administrators of frame relay networks can recognize the quality of the ATM network suitably and manage the frame relay networks in accordance with the quality condition of the ATM network. When a frame F is transmitted from a frame relay network FR1 at a transmitting side to an IWF, a frame header in which a transmission number is stored is added to the frame F. Then, the frame F is received by a frame relay network FR2 at a transmitted side through the IWF and the ATM network. In the frame relay network FR2, a difference between the transmission number stored in the frame header of the frame F and a reception condition variable kept in the frame relay network FR2 is calculated, and the difference is stored in a quality information collection table as a number of discarded frames in the ATM network.

  • Patent number: 5936944
    Abstract: In a network system according to the present invention, in the case where a plurality of calls are set between specific terminal and the other terminal unit to conduct communication, when a communication fault is detected in a frame relay network, a representative call is decided from the plurality of calls, and all the calls except for the representative call are released. Thereafter, a call cut message including information relating to the calls to be released is transmitted from the frame relay network. In the specific terminal, the calls except for the representative call are released on the basis of the information of the calls to be released which is contained in the call cut message to transmit the call release message of the representative call. In the frame relay network, the representative call is released according to the call release message to transmit the call release completion message. Then, in the specific terminal, the representative call is released.

  • Patent number: 5145466
    Abstract: A limited slip differential for a vehicle comprises a friction clutch disposed between a differential gear mechanism and a drive wheel axle, a clutch control cylinder for coupling and decoupling the friction clutch, a normally closed type solenoid valve for charging compressed air to the cylinder from a pressure air source and a normally opened type solenoid valve for discharging compressed air from the cylinder to the air. The normally closed type and normally opened type solenoid valves are operated by a control unit in response to a low .mu. road start, a low .mu. road run, a straight run and a brake so as to charge and discharge compressed air to and from the cylinder and thereby to control air pressure in the cylinder. A power device for a vehicle is composed by adding an engine control cylinder disposed in an acceleration control mechanism and an engine control valve for charging and discharging compressed air to the cylinder, and wherein during a low .mu.
