  • 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.

  • Patent number: 6742399
    Abstract: A respiratory flow sensor, which is suitable for use near a patient, covers a broad gas volume flow measuring range with a low breathing flow resistance and good, reproducible measured signal quality at the same time. The respiratory flow sensor has a first air resistance body (3) with a blunt end and with an opposite pointed end. The air resistance body (3) is arranged between the measuring transducer (5), of which there is at least one, and the patient-side end (P) of the respiratory flow sensor. The pointed end of the first air resistance body (3) points toward the measuring transducer (5). A second air resistance body (4) with a pointed end is arranged between the measuring transducer (5), of which there is at least one, and the end of the respiratory flow sensor that is away from the patient.

  • 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. Each of the transmit queues include an input queue, an expansion queue and an output queue. The switch also includes control logic for directing the removing of one of the available buffer descriptors from the free pool and directing one of the packets from the receiving module into one of the buff cells corresponding to the one available buffer descriptor. The control logic places the one buffer descriptor in the input queue of one of the transmit queues. The control logic also monitors a load status of the input and output queues.

  • 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).
