The invention concerns a method for showing three-dimensionally defined fiducial points in a video camera image involving monitoring of a spatial region by at least two cameras which can map invisible light, especially infrared light, and by at least one video camera, computer-assisted analysis of the image data of the cameras, using the three-dimensional data obtained by means of the invisible-light cameras to compute the spatial location of objects located in the monitored spatial region as ma...

A transducer for measuring linear positions comprises a scale formed of a tensioned flexible band and a slide movable with respect to the scale. A rigid guide plate fast with the slide extends over the whole area of the slide winding and cooperates with a resilient plate having guide lugs at each end of the guide plate and so bent as to have lips bearing against two edges of the band. A leaf spring element on the resilient plate urges the lips against the side of the band opposite to the plate.

A profile is created for making correspondence between a lattice point in an ink color space composed of ink colors and a lattice point in a device-independent color space by: defining a virtual force acting on a focused lattice point in a device-independent color space and obtaining the focused lattice position in a stable state reached when the virtual force acts on the focused lattice point; and working based on a transform model for transforming a lattice point in the ink color space into a ...

A bed having upper and lower bunks. In order to make it easy to "make" the bed the upper bunk can be moved sidewise and then tilted to give a person desiring to make the bed easy access to the upper bunk. The axis about which the upper bunk is tilted may be selected to enable the tilted bunk to be higher or lower as desired. The movement of the bunk is provided by cam surfaces on the frame of the bed and cam followers on the mattress trays of the upper bunk. One set of cam followers act as a piv...

An apparatus is disclosed for digitizing positions on a transparency. The apparatus includes a cool light box and an acoustic digitizer.

A creeper (10) includes a main frame (11) which is rendered mobile by caster assemblies (14, 15, 16). A pivot frame (22) is pivotally attached to the main frame (11) and carries a pad section (19). Another pivot frame (28) is pivotally attached to the main frame (11) and carries another pad section (20). A floating frame holding mechanism (50) is provided to maintain a selected pivotal position of the pivot frame (22) relative to the main frame (11), and a frame holding mechanism (34) is provide...

An exhaust processing system for a boat including an exhaust chamber having an exhaust opening in the rear bottom thereof, and a wedge plate is pivotally mounted at the forward end of the opening. Controls are provided to pivot the wedge to thereby change the negative pressure in the exhaust chamber

A path and/or position measuring device is provided, including a magnet and a sensor for detecting the magnetic field intensity. The magnet and/or the sensor cooperate with a movable element. The magnet is formed such that the magnetic field intensity varies along an axis of the magnet and is not constant. The relative movement between the sensor and the magnet is substantially in the direction of the axis of the magnet. The path and/or the position of the movable element can be determined based...

A knife having angularly adjustable cutting positions is provided, comprising a blade having a base portion, the base portion having an outer edge including an engagement portion including a positioning mechanism for positioning the blade in multiple angular cutting positions with reference to a handle; a handle including a biased locking member for selectively engaging the positioning mechanism and fixing the blade in each of the angular cutting positions, the handle having a blade end; a sprin...

A method for increasing accuracy and reducing the time required to teach the target bonding points on a reference semiconductor device and its associated lead frame comprises manually approximately locating at least a first target bonding point and at each approximately located bonding point causing the pattern recognition system (PRS) of an automatic wire bonder to relocate the exact center of preferred target bonding point automatically. The direction and approximate distance to the next point...
