  • Patent number: 8996142
    Abstract: A predictive alignment process for aligning coupled rotating shafts extending from a pair of adjacently located rotating machines. The process includes a step of monitoring the rotating machines to obtain physical characteristics that change during operation and could cause variance in alignment between a non-operating state and an operating state. The process would monitor changes in alignment and correlate the changes in physical characteristics and the operational alignment. The process can monitor and record environmental conditions proximate the rotating machinery and correlate the operational alignment and the environmental changes to provide predictive alignment directions used to guide an alignment engineer to align coupled shafts where the alignment is optimized when in operation.

A combined spatial position and/or orientation for the host device may be obtained based on raw measurements that are obtained from at least two different types of sensors. In addition, a spatial position and/or orientation for an accessory device is ascertained using one or more sensors of the accessory device. An orientation (or position) of the accessory device relative to the host computing device may then be computed based on the combined spatial position/orientation for the host computing device and the ascertained spatial position/orientation for the accessory device. The relative orientation that is computed may then be used in various ways to control behaviors of the host computing device and/or accessory device.

    Abstract: A method for aligning a stent with a stent support includes the steps of (1) placing a stent support and a stent mounted on the stent support in a vertically position with the stent support's first support element at a lower position and the stent support's second support element at an upper position; (2) obtaining a digital image of the stent support and stent; (3) analyzing the digital image of the stent support and stent to compute the vertical position of the stent's upper end; (4) computing a desired position of the second support element based on the position of the stent's upper end; and (5) using a positioning device to move the second support element to the desired position. The movement of the second support element causes the conical sections of the first and second support elements to engage the respective ends of the stent to center the stent around a core element of the stent support and to secure the stent in a longitudinal direction of the stent support.

  • Patent number: 7792622
    Abstract: The method and system for vehicular guidance comprises an imaging device for collecting color image data to facilitate distinguishing crop image data (e.g., crop rows) from background data. A definer defines a series of scan line segments generally perpendicular to a transverse axis of the vehicle or of the imaging device. An intensity evaluator determines scan line intensity data for each of the scan line segments. An alignment detector (e.g., search engine) identifies a preferential heading of the vehicle that is generally aligned with respect to a crop feature, associated with the crop image data, based on the determined scan line intensity meeting or exceeding a maximum value or minimum threshold value.

  • Patent number: 7774083
    Abstract: Methods and systems for position sensing are disclosed. In one embodiment, a method includes measuring at least three discrete point positions associated with a first component using at least one transmitter having a known position and orientation and in a line of sight with the three discrete point positions, the three discrete point positions having known distances relative to one another. The method computes a current position and orientation of the first component using data provided by the at least one transmitter and the three discrete point positions, along with position and orientation data from a last known location of the first component assuming that no sudden position changes since the first component has moved from the last known location. The first and second components may be a workpiece and a tool that performs a manufacturing operation on the workpiece.

  • Publication number: 20100138006
    Abstract: Device and method for positioning a precision part on a turntable (130). The device (100) comprises at least two distance sensors (121.1, 121.2, 121.3), which operate in a contactless manner and are situated in a previously known configuration to a rotational axis (A1) of the turntable (130). The measurement axes (124.1, 124.2, 124.3) of the distance sensors (121.1, 121.2, 121.3) are radially oriented in the direction of the rotational axis (A1) so that the measurement axes (124.1, 124.2, 124.3) of the distance sensors (121.1, 121.2, 121.3) meet in a virtual measuring point (MV). The distance sensors (121.1, 121.2, 121.3) are connected to analysis electronics (200). Output signals (a.1, a.2, a.3) of the distance sensors (121.1, 121.2, 121.3) may be processed on the basis of the analysis electronics (200), in order to allow coaxial centering of the precision part (11) in relation to the rotational axis (A1) upon placement of the precision part (11) on the turntable (130).

  • Patent number: 7714856
    Abstract: The invention relates to a method and to a device for the representation of a predeterminable region (3) in multidimensional data sets (2). The data sets (2) are especially made of three or four dimensional image data of an object which is to be examined. The image data is produced by means of one or several receiving elements of the object and especially at least one two-dimensional cut (S) is located and displayed through the predeterminable region (3). The cut (S) is defined by at least one vector plane and/or indicator plane (E1, E2), which are arranged in the multi-dimensional data set (2), by means of a vector (4). Said vector or indicator is fixed by manipulation in the multidimensional data set (2) and/or on, particularly, the two-dimensional cut planes (S1, S2) of the multi-dimensional data sets (2) on at least one vector plane (E1, E2) and the vector and/or indicator (4).

  • Patent number: 7711441
    Abstract: Plural energy beam sources are aimed at an energy receiving device by way of feedback control signals. Each energy beam is uniquely modulated by way of amplitude, polarization and/or coning patterns to enable individual detection and control. Sensors detect individual energy beams incident to the energy receiving device and provide corresponding detection signals. Control electronics receive the detection signals and derive one or more control signals that are coupled to the plural energy sources. Aircraft and other vehicles are thus provided with electrical and/or thermal energy without the need for source-to-vehicle cabling or substantial on-board energy resources.

  • Patent number: 7680551
    Abstract: An industrial robot includes a first member, a positioning member arranged to be attached to the first member, a second member arranged to rotate relative to the first member, and a first joint for coupling the first member with the second member. The second member has a contact point arranged to contact the positioning member. An indication for requesting to enable the positioning member to contact the contact point is displayed. The second member rotates at the first joint relatively to the first member while the positioning member can contact the contact point. It is detected whether or not the contact point of the second member contacts the positioning member. A position of the second member is stored as an origin when it is detected that the contact point of the second member contacts the positioning member. This method prevents a possible failure of the attaching of the positioning member, and decreases a work load on an operator.
