Publication number: 20220381875Abstract: A real-time locating system of the present disclosure may be used in connection with a particular facility and may include a tag associated with an object disposed within the facility. The tag may be configured to continuously emit radio frequency signals encapsulating a tag identifier and a battery status. The real-time locating system may also include a sensor positioned at a known location within the facility. The sensor may be configured to receive radio frequency signals from the tag and determine an associated signal strength. The real-time locating system may be configured to utilize the known location of the sensor and the signal strength of the radio frequency signal to determine the location of the tag and thus the object within the facility.Type: ApplicationFiled: May 27, 2022Publication date: December 1, 2022Inventors: Hall T. Snowday, III, Anthony E. Brown, James L. Overbeck

Patent number: 7545499Abstract: A method for measuring a flexible colored material during a manufacturing process. The method includes automatically diverting the flexible material from a process path, placing the flexible material in contact with a rotatable drum, and measuring spectral data of the flexible material as the drum rotates. Measuring the spectral data includes scanning the flexible material with a line scanning detector having an array of detectors. The method also includes processing scan information to form a single image of the flexible material.Type: GrantFiled: April 12, 2006Date of Patent: June 9, 2009Assignee: X-Rite, Inc.Inventors: James L. Overbeck, Richard J. Van Andel

Patent number: 7480035Abstract: Imaging that uses glare to confirm proper measurement of a sample. An imaging device illuminates an object and generates glare (i.e., specular reflection, diffuse reflection or a combination of the two) off the object's surface, which is displayed on a display as a glare artifact. The location of the glare artifact is compared to a predetermined location to establish adjustment to obtain a desired angular orientation. The imaging device optionally highlights the glare artifact and steers a user to obtain the desired presentation angle. In two other embodiments, the spatial relationship between the imaging device and the object is time-varied. In one, the imaging device monitors changing glare and acquires a measurement when a desired glare is detected. In the other, the imaging device captures multiple images including varying glare artifacts and analyzes the images to select a preferred image having a glare artifact indicative of a desired angular orientation.Type: GrantFiled: December 29, 2005Date of Patent: January 20, 2009Assignee: X-Rite, Inc.Inventors: James L. Overbeck, Richard J. Van Andel

Patent number: 7268879Abstract: A color measurement instrument includes a housing and illuminators, a two-dimensional photodetector array, and an optics system within the housing. A UV filter wheel closes the housing to prevent contaminants from entering the housing. The filter wheel supports UV filters and non-UV glass that can be selectively aligned with the illuminators. The photodetectors can be read in parallel, and each photodetector includes a unique spectral filter. The optics system delivers light from the sample target area equally to each of the photodetectors.Type: GrantFiled: April 28, 2005Date of Patent: September 11, 2007Assignee: X-Rite, Inc.Inventors: Richard J.

Patent number: 7050168Abstract: An instrument and related process for measuring color, shade, gloss, shape and/or translucence of a tooth. First, the instrument uses searchlight illumination to illuminate a tooth with constant irradiance. Second, the instrument uses calorimetric imaging to collect time-separated frames of different wavelengths of light reflected from a tooth and to combine those frames into a color image. Third, the instrument includes a sanitary shield to establish a reference color and a predetermined distance to a target tooth. Fourth, the instrument provides line-of-sight viewing so an operator may simultaneously view a display of the image on the instrument and the object being measured. Fifth, the instrument is impervious to pollutants because it incorporates a sealed measurement window. Sixth, optical measurements of a tooth taken by a dentist are compared to optical measurements of a prosthetic restoration for that tooth to confirm satisfactory matching of optical characteristics of the tooth and restoration.Type: GrantFiled: December 8, 2000Date of Patent: May 23, 2006Assignee: X-Rite, IncorporatedInventors: James L.

Patent number: 5400138Abstract: A color measuring system includes a portable spectrophotometer connectable to a general-purpose computer. The portable unit includes a microprocessor with a read-only program memory storing machine executable instructions to implement data processing for color measurement purposes and input/output functions including key reading and data transfer functions and display functions. A random-access data memory is used to temporarily store process data for later transfer to the general-purpose computer. An editor program and a compiler program in the general-purpose computer may be used to generate a program for the microprocessor using high-level, generalized commands. After such a program has been written and compiled in the general-purpose computer, it is transferred to a command buffer area in the random-access data memory of the microprocessor.Type: GrantFiled: November 20, 1992Date of Patent: March 21, 1995Assignee: X-Rite, IncorporatedInventors: Steven H.
