| 20100201589 | DEVICE AND METHOD FOR CONTROLLING A SATELLITE TRACKING ANTENNA - A device for controlling a satellite tracking antenna. An azimuth drive is configured to impart an azimuthal rotational motion to the antenna about an azimuth axis. An elevation axis drive is configured to impart a rotational motion to the antenna about an elevation axis orthogonal to the azimuth axis. A tilt axis drive is configured to impart a rotational motion to the antenna about a tilt axis. The tilt axis is connected to the elevation axis in such a way that the rotational freedom of motion of the antenna about the tilt axis is dependent on the elevation angle such that: at an elevation angle of 0° the rotational freedom of motion of the antenna about the tilt axis corresponds to the azimuthal rotational motion; at an increasing elevation angle the rotational freedom of motion about the antenna successively transcends into a roll rotation; and at an elevation angle of 90° the rotational freedom of motion of the antenna about the tilt axis corresponds to a roll rotation about a roll axis orthogonal to the azimuth axis and to the elevation axis. A control controls the operation of the azimuth axis drive, the elevation axis drive, and the tilt axis drive. The control includes a true north seeking gyro for tracking position, orientation, direction and speed of movement of the device. The control further includes an additional gyro comprising an elevation gyro axis arranged to sense the elevation movement and a tilt gyro axis arranged to sense the tilt movement, so as to minimize the angular velocity of the antenna pointing vector. A method for controlling a satellite tracking antenna, and a vessel including the device. | 08-12-2010 |

| 20090078103 | DETERMINATION OF BAND SAW FEEDING SPEED - In a method and a system for determining the feeding speed when bandsaw cutting a workpiece, the tooth pitch TP of the bandsaw blade is determined in a first unit depending on the shape and dimensions of the workpiece. In a second unit feeding depth per tooth is determined depending on properties of the workpiece material and the width of the bandsaw blade. The bandsaw blade velocity BS is determined in a third unit from the width W of the workpiece and the hardness of the workpiece material, whereafter the cutting time T is determined in a first calculating unit from the height H of the workpiece, the feeding depth per tooth, the tooth pitch TP and the blade velocity BS. In a second calculating unit the feeding speed MH for the bandsaw blade is then determined by the equation MH=H/T. A computer program, when executed on a computer, performs this determination of the feeding speed when cutting a workpiece with a bandsaw from supplied input data. | 03-26-2009 |

| 20100016991 | Prosthetic product having composite material wall, and method for producing the prosthetic product - The invention relates to a prosthetic product having a composite material wall moulded into the shape of a part of a body, characterized in that the wall of the prosthetic product is composed of, on one hand, an reinforcing textile including continuous length fibres, and on the other hand, a textile matrix including thermoplastic polymer fibres, preferably of continuous length. Analogously herewith, the invention also relates to a process for the manufacture of a prosthetic product comprising a composite material wall moulded into the shape of a part of a body, comprising the following manufacturing steps: providing a mould onto which the composite material wall is to be formed; applying an reinforcing textile including continuous length fibres onto the mould; applying a matrix textile including thermoplastic polymer fibres preferably of continuous length onto the mould, at least externally of the reinforcing textile, and melting the polymer matrix fibres for embedding of the reinforcing textile fibres in a thermoplastic polymer matrix, followed by cooling and consolidation of the composite material wall. | 01-21-2010 |

| 20090114053 | Arm part of an industrial robot as well as an industrial robot provided therewith - An arm part of a manipulator of an industrial robot has at each end thereof a connector for connecting the arm part to a gear and a stiffener for stiffening the end region of the arm part. At least one aperture is arranged in a hollow structure of the stiffener for providing access to connecting members. | 05-07-2009 |
| 20100217434 | Method and Device for Controlling Motion of an Industrial Robot With a Position Switch - A method for controlling a multi-axis industrial robot or manipulator arranged with a robot control unit. The robot or the control unit includes at least one first computer running a servo controller. A motion limit is configured for at least one axis of the robot arm. A reference signal for a robot position is sent to a robot controller together with a measurement of a position of the robot arm. The reference position is processed and the measured position and the processed reference position are then compared in an evaluator for the purpose of limiting the motion of an arm of the robot. | 08-26-2010 |

| 20090184497 | SIDE CURTAIN AIR-BAG - In at least one embodiment of the present invention, an inflatable curtain for a motor vehicle is provided. The inflatable curtain is formed of layers of fabric and is deployable from a rolled state forming a roll to an inflated state. The air-bag comprises part of the air-bag that forms the upper-most edge of the air-bag when the air-bag is in the inflated state extending downwardly from the roll to lie proximate a side part of the motor vehicle on which the air-bag is to be mounted. At least a portion of the roll is positioned above the upper-most edge in the rolled state and is driven downward below the upper-most edge during deployment to the inflated state. The air-bag further provides a gas flow duct. When the air-bag is in the rolled state, the gas flow duct is provided at the top part of the roll. | 07-23-2009 |
