Abstract: An object tracking system comprising one or more objects, a processing device, a memory device and one or more cameras. Each of the objects comprise a unique visual marker positioned on a top surface of the object, wherein the unique visual marker comprises a series of concentric rings that represent data that uniquely identifies the object. As a result, during the course of operation, the location and identification of the objects are able to be determined by the processing device by analyzing images captured by the one or more cameras of the visual markers of the objects on the game board. The processing device is able to disregard incomplete or corrupt data from the visual markers due to the visual marker being blocked from view or otherwise corrupted and thereby still correctly identify and locate the objects.

Abstract: According to the method, drops of an adhesive material are deposited on one of the plates, with the drops being spaced from one another. A grid having a predefined thickness lower than that of the drops is applied to the plate receiving the drops. A perpendicular and uniform pressure is applied to at least one of the plates, so that the drops spread and come into contact with the opposing sides of the two plates. The spacing of the drops is defined so that after spreading under the pressure applied, air is not trapped between the drops.

Abstract: In operating a gas turbine, there can be a difference between the desired heating value of the fuel and the actual needs of the fuel for the supplied fuel to be ignited. In one aspect, fuel parameters related to the molecular weight of the fuel such as specific gravity and pressure drop are determined. Ignitability of the fuel is calculated based on the fuel parameters and adjusted as necessary to bring the fuel's ignitability to designed values. The fuel's ignitability can be calculated without actually igniting the fuel and also without direct knowledge of the fuel's calorific value or its composition.

Abstract: The invention relates to a method for securing the execution of an onboard NFC application in a secure element which does not include a native OTA application. The secure element interacts with a mobile terminal including a removable card. According to the invention, the method includes recording an identifier of the removable card in the secure element no later than when the NFC application is loaded onto the secure element. When an event occurs, a verification is made, in the secure element, whether or not the identifier of the removable card present in the mobile terminal corresponds to the identifier previously stored in the secure element, in order to detect a possible change of the removable card.

Abstract: (EN) The invention makes it possible to allow several applications to coexist in the same card; the implementation of the applications uses reading and writing of data by the reader in the same memory location. The invention is a method for exchanging data between a mobile authentication device 3 supporting several applications Z1 to Z3 and a reader dedicated to one application in which the reader sends an authentication command and at least one read and/or write command. The authentication command allows the mobile device to authorise a transaction for at least part of an application Z1 to Z3 supported by the said mobile device. In response to the authentication command, the mobile device selects the application of the device that corresponds to the reader. The read and/or write command is carried out by addressing a definite block of data. In response to the read and/or write command, the mobile device addresses the block of the selected application.
