Patent number: 11354238Abstract: A method can be used to determine an overall memory size of a global memory area to be allocated in a memory intended to store input data and output data from each layer of a neural network. An elementary memory size of an elementary memory area intended to store the input data and the output data from the layer is determined for each layer. The elementary memory size is in the range between a memory size for the input data or output data from the layer and a size equal to the sum of the memory size for the input data and the memory size for the output data from the layer. The overall memory size is determined based on the elementary memory sizes associated with the layers. The global memory area contains all the elementary memory areas.Type: GrantFiled: November 22, 2019Date of Patent: June 7, 2022Assignee: STMICROELECTRONICS (ROUSSET) SASInventors: Laurent Folliot, Pierre Demaj

Patent number: 11356830Abstract: A first object and a second object are movable in relation to one another. The first object includes a transponder using an integrated circuit having two terminals which may or may not be shorted. The presence or absence of a short circuit between the two terminals is detected. This is accomplished at least partly by the second object depending on the relative positioning of the first and second objects. The transponder transmits, to a module having a contactless reader function, positioning information corresponding to said relative positioning using a contactless communication protocol.Type: GrantFiled: November 16, 2020Date of Patent: June 7, 2022Assignee: STMicroelectronics (Rousset) SASInventor: Jean-Louis Demessine
