  • Method for limiting the force action of a robot part
    Patent number: 6748298
    Abstract: In order to reduce the risk of damage on external objects, material articles or persons during the operation of a robot, particularly a miniature robot, the invention provides a method for limiting the force action of a robot part, such as a robot arm, on such an external object during a collision in such a way that as a result of a maximum permitted force, maximum force Fmax, acting on the object in the case of a collision, a corresponding, maximum permitted kinetic energy, maximum energy Ekin,max of the robot part is determined, continuously and at adequately short time intervals the actual kinetic energy, actual energy Ekin, of the robot part is determined and on exceeding the maximum permitted energy Ekin,max, the actual operating speed V of the robot is reduced.

  • Transmit queue caching
    Patent number: 6735210
    Abstract: A computer network switch includes a receiving module for receiving packets, a packet memory with a plurality of buffer cells with each of the buffer cells having a buffer descriptor. A descriptor free pool lists available buffer descriptors that can be used for new incoming packets. A plurality of transmit queues hold the buffer descriptors.

  • Fibre-reinforced plastic part
    Patent number: 6730394
    Abstract: On joining a fibre-reinforced plastic part, such as a plastic fibre-reinforced robot arm, to a functional element such as a gear, as a result of the flow characteristics of the plastic in the case of a high pressing action or high pressures, the joints are no longer stable or resistant and instead tend to loosen. To obviate this problem, the invention provides a fibre-reinforced plastic part, in which several metallic parts (6) engage through at least one fibre-reinforced shoulder (4). On one side of the shoulder or shoulders (4) is provided at least one metallic abutment (8) engaging over several metallic parts (6) and a functional element (2) is braced from the opposite side of the shoulder or shoulders (4) with the abutment (8) against the front ends (6a), facing the latter, of metallic parts (6).
