Patent number: 11415470Abstract: A method of monitoring a HVAC system to detect erroneous sensor installation. The method includes determining whether a circulation fan has been operational for a first predetermined time interval. If the circulation fan has been operational for the first predetermined time interval, determining whether a cooling demand is present. If the cooling demand is present, determining whether the HVAC system has been conditioning air for the first predetermined time interval responsive to the cooling demand. If the HVAC system has been conditioning the air for the first predetermined time interval, determining whether a difference between an indoor air temperature value corresponding to an enclosed space and an air temperature value from a discharge air temperature (DAT) sensor is greater than a predetermined temperature value.Type: GrantFiled: February 7, 2020Date of Patent: August 16, 2022Assignee: Lennox Industries Inc.Inventors: Payam Delgoshaei, Sridhar Venkatesh, Glenn W.

Patent number: 8319723Abstract: A method and a system for improving the psychovisual experience of watching a display are presented. Measurements on the ambient light are performed by a sensor element, from which characteristics of the ambient light are derived. These are subsequently applied in a light-source adjustment model to determine the output of the light-source element. Moreover, a method and a system for adjusting the output of a light-source element by a feed-back loop involving the output from the light-source element and the input to a sensor element are revealed. In addition, the sensor element is also employed for adjusting the output of an electronic display by applying the results of the measurements to a preference model.Type: GrantFiled: July 30, 2008Date of Patent: November 27, 2012Assignee: Bang & Olufsen A/SInventor: Lars Nørgaard

Patent number: 8159616Abstract: The present invention relates to a method and corresponding system for improving the perceived visual quality of images for instance displayed on a color television screen. According to the invention, there is provided a means for carrying out histogram processing (13) for scaling an input video signal (6) such that the maximum dynamic range is utilised and where the quality of the perceived image is also optimised. According to the invention, the histogram processing (13) provides a transfer function for the image pixels to obtain enhanced image dynamics and also to provide a chrominance gain (gc) for scaling the chrominance components, when the luminance has been changed by the histogram processing. According to the invention, the histogram processing can also take variations of the ambient light into account (5).Type: GrantFiled: March 27, 2008Date of Patent: April 17, 2012Assignee: Bang & Olufsen A/SInventor: Lars Nørgaard

Patent number: 6834237Abstract: The present invention relates to a method of training a classification system for characterising a biological sample, a diagnostic classification system, as well as a method of characterising a condition in an animal or a human being by using parameters obtained from the sample. The invention relates to classification based on physical parameters obtained from luminescence spectroscopy on light emitted from the sample. The data obtained from a spectrofluorimetric analysis can be considered a finger-print of the sample. Each sample gives rise to a unique spectrofluorometric set of physical parameters. By analysing the fluorescence data, it is possible to classify samples into two or more classes based on the fluorescence spectra, such as classifying with respect to presence/abs of a specific disease, group of diseases or risk of later attaining a specific disease or a body condition, or concentration of a specific compound or medicine.Type: GrantFiled: April 16, 2003Date of Patent: December 21, 2004Assignee: Medicometrics APSInventors: Lars Noergaard, Morten Albrechtsen, Ole Ingemann Olsen, Niels Harrit, Rasmus Bro-Joergensen
