A Network Interface device coupled to a host computer receives a multi-packet message from a network and DMAs the data portions of the various packets directly into a destination in application memory on the host computer. The touch panel includes a plurality of pixels, wherein each pixel includes M*N sub-pixels, at least m sub-pixels each include at least one photo sensitive area and at least one effective display area, the other n sub-pixels each include only at least one effective display area, and M\u22672, N\u22671, m\u2266M, m+n=M and m\u22670. The robot has a moving mechanism. One or more cam lock bores adapted to house one or more at least partially rotatable cam locks, are offset from the pin cam bores such that each cam pin bore partially intersects a corresponding cam lock bore to form an aperture through which the cam lock engages the cam pin. An angular velocity of a hip of a swinging leg is obtained by measuring the angleangular velocity of an ankle pitch joint part of a supporting leg in real time when the robot walks on the two-dimensional space, and desired trajectories of the ankle and the hip are generated based on the angular velocity of the ankle of the supporting leg and the angular velocity of the hip of the swinging leg. A third series of strip sections is laid down onto the toroidal support.
