A system for monitoring gluten consumption, especially in celiac people, which allows the feeding of food consumption data and updating, in real time, of the estimated amount of gluten consumed daily. Still, the present invention refers to a system for prediction that associates the possibility of an indisposition being associated or not with an undue consumption of gluten.

There is provided an encoding and decoding method and an information recognition device using the same. A code block includes a center coding region and a peripheral coding region arranged around the center coding region. The encoding and decoding method uses the feature of at least one microdot included in the center coding region as codes. The encoding and decoding method uses the feature of at least one microdot included in the peripheral coding region as codes. The encoding and decoding method uses the relative feature between the center coding region and the peripheral coding region as codes. The information recognition device compares the read feature with pre-stored features to decode information such as position codes, object codes, parameter codes and control codes.

An electronic device is disclosed that includes a camera, a display, and a processor. The processor is configured to obtain a request associated with biometric authentication, obtain an image including at least one external object using the camera, display a specified image on the display, when displaying at least a portion of the obtained image on a specified area of the display, the at least a portion of the obtained image being as a portion of the specified image, in response to displaying a specified object associated with the biometric authentication among the at least one external object on the specified area, perform the biometric authentication using biometric information corresponding to the specific object, and when displaying another image different from the obtained image on the display, the other image being as a portion of the specified image, in response to obtaining an image including the specified object among the at least one external object, perform the biometric authentication using the biometric information corresponding to the specified object. In addition, various embodiments recognized through the specification are possible.

In each page of a calendar or a notebook in which a rectangle paper is folded in eight with one side thereof divided into four equal parts and the other side thereof divided into two equal parts and each of front and rear regions of the rectangle paper divided into equal parts by folded lines serves as a page, an identifier which enables specification of the position of the page in the whole rectangle paper is printed. The identifier includes, for example, a combination of alphabets, numerals, and colors. In another embodiment, the identifier is an icon printed at a corner of each page. The icon has a high density portion, and the position of the page with respect to the whole rectangle paper is expressed as the position of the high density portion with respect to the whole icon.

A method of aligning a component to a structure in a diagnostic laboratory system. The method includes aligning a position sensor to the structure; sensing a position of the component using the position sensor; and calculating the position of the component relative to the structure based at least in part on the sensing. Other methods, apparatus, and systems are disclosed.

A computer-implemented method of calibrating an electronic display screen for touchless gesture control using a calibration device, wherein the method comprises: displaying, by the electronic display screen, a calibration pattern; detecting, using at least one depth camera, a calibration device being placed on the electronic display screen and a reflection of at least a part of the calibration pattern, wherein the reflection is provided by a reflective surface of the calibration device; determining, based on the detected reflection, the position of the calibration device with respect to the displayed calibration pattern on the electronic display screen; defining a touchless gesture control input area for the electronic display screen being observable by the at least one depth camera.

A display apparatus includes a display, a communication module that communicates with an input device, and a processor. The processor is configured to add pattern information to a first image by changing a pixel value of at least one of a plurality of pixels included in the first image, to display the first image, to which the pattern information is added, on the display, to receive a second image captured by the input device from the input device via the communication module, and to identify input coordinates of the input device or a function to be executed by the display apparatus based on pattern information included in the received second image.
