761 results about "Laser pointer" patented technology

A laser pointer or laser pen is a small handheld device with a power source (usually a battery) and a laser diode emitting a very narrow coherent low-powered laser beam of visible light, intended to be used to highlight something of interest by illuminating it with a small bright spot of colored light. Power is restricted in most jurisdictions not to exceed 5 mW.

System for tracking surgical items in an operating room environment

A system for tracking and locating surgical items and objects in an operating room environment that incorporates two-stage functionality. A first stage provides mechanisms for tracking objects using radio frequency (RF) tags that are positioned on or in conjunction with every surgical item and object so as to be tracked by a number of RF transceivers located about the operating room. In addition to integrating RF ID components, the tags integrate hard spherical components that are easily identifiable by ultrasonic detection. If an object is “lost” from the tracking system functionality (RF tracking), the system operator may review a last known location and movement path presented on a display and thereafter utilize an ultrasonic sub-system in a localized area to detect the exact location of the missing object or item. Narrowing the location of a “lost” object is facilitated by the use of one or more LED laser pointers that are directed through the last known path of the object and to its last known location.

Method and apparatus for an interactive volumetric three dimensional display

A process and system for interactively displaying large (more than 1 million voxels) volumetric 3D images utilizing a sequence of helical slices of a 3D data set to generate a series of 2D images on a reflective surface of a light modulator. The series of 2D images generated on the light modulator are projected into a volumetric 3D-space display using an illumination light source and projection optics. Voxels in 3D space are illuminated for each 2D projected image, each voxel being located at its corresponding spatial location. A pulse from a wireless pulsed laser pointer forms a 3D bright voxel within the display volume. The pulse signal is synchronized with the rotating helix, and the orientation of the pointer and the phase of the pulse are controlled by the user to specify a 3D point in 3D space. A wireless receiver provides six degree-of-freedom (DOF) position of the spatial location of the pointer, as well as the phase signal. Optical encoders provide synchronization signals of the rotating helical display.
