摘要： An angle of rotation detector has a drive unit which supplies 90 degree phase shifted signals to a pair of stator coils and measures an analog output from a rotor coil in a resolver. A calculating device calculates the rotational angle of the resolver using the output of an analog to digital converter receiving the analog output of the rotor. In one embodiment, the calculating device performs a Fourier transform to compute the phase of a fixed frequency component contained in the output of the rotor coil. In another embodiment, the drive unit supplies signals wherein f(T/2+t)=-f(t) and the calculating device performs a Fourier transform using data from successive half periods of the drive waveform. In another embodiment, the output of the rotor is sampled at 1/4 period of an excitation signal from the drive unit and the calculating device determines the phase difference between the excitation signal and the rotor output. In still another embodiment, the calculating device compares the outputs at two or more points having a fixed time relationship and compares the results to stored reference data to arrive at the angle of rotation.

摘要： A data communication method and apparatus for a mobile network. A destination foreign agent (FA2) recognizes a MAC address of an MN. The FA2 registers the MAC address of the MN in a handoff request message (FHReq), and the FA2 feeds the FHReq onto a transfer network. Each of foreign agents (FAs) receives the FHReq, registers an IP address corresponding to the MAC address in the FHReq when the MAC address is registered in a binding list of the FAs themselves, and feeds the IP address onto the transfer network. The FA2 receives the FHReq, and temporarily registers the MAC address and the IP address in the binding list of the FA2 itself. The FA2 transfers data sent from a homw agent (HA) to the MN, based on the information which has been temporarily registered.

摘要： Disclosed herein is an optical disc apparatus for applying a light beam to a surface of an optical disc and detecting a return light beam from the surface of the optical disc. The apparatus includes a light detector for detecting the return light beam having: a light detector having: a first divided area and a second divided area which are divided from each other at the center of the return light beam in a direction perpendicular to a track on the surface of the optical disc; and a third divided area and a fourth divided area which are positioned respectively outwardly of the first divided area and the second divided area in the direction perpendicular to the track. The first and second divided areas are positioned so as not to overlap an area where zeroth-order light and first-order light contained in the return light beam overlap each other.
