A system for providing monitoring of commercial cooking equipment includes a database comprising a plurality of device records, and a plurality of technician records. The system further includes a computing device comprising a network interface device, a sensor coupled to the cooking unit, and a processor for reading the sensor data from the sensor and transmitting the sensor data to a server. The system further includes a server for receiving the sensor data, finding a technician within the vicinity that can service the cooking unit, and sending a message to the technician including the sensor data and the contact information for the owner of the cooking unit, so that the technician may service the cooking unit. The system is further configured for monitoring the performance and usage of the cooking unit; identifying potential problems and issues with the cooking unit; and sending a message to customers.

A cooking apparatus including an image capturer and a processor configured to identify a food object from a plurality of images obtained through the image capturer, adjust a capture interval at which an image of the food object is obtained in real time through the image capturer based on information about a cooking state change of the identified food object, and generate a video based on the captured image obtained according to the adjusted capture interval.

A method and system to determine one or more proportional particle group shares in flue gas of a recovery boiler (110) based on optical information gained from a flue gas sample. A processor (202) is used to read (301) a digital frame comprising the area under consideration, which represents at least a part of the surface of a sampler (120) kept in the flue gas flow of a recovery boiler. Particle group areas matching a color characteristic of the particle group comprised in the flue gas is determined (302) from the area under consideration. The joint area of the identified particle group areas is determined (304), and the share of the joint area from the total area is determined (305) as the proportional particle group share of the particle group.

According to the disclosed embodiments, an illustrative apparatus that is configured to attach to a viewport of a container comprises a first plate having a first aperture and an attached second plate having a second aperture substantially aligned to the first aperture. The first and second plates, when attached, define a cavity from an outer edge of the first and second plates to the substantially aligned apertures. A window containment arm is pivotally affixed to at least the first plate and configured to substantially fit and pivot into and out of the cavity, and a window contained within the window containment arm is positioned such that the window substantially aligns with the first and second apertures when the window containment arm is fully pivoted into the cavity, and such that the window is accessibly located outside of the cavity when the window containment arm is pivoted out of the cavity.
