Abstract: The technology disclosed herein relates to a transcutaneous irradiation device having a top portion and a bottom portion. The top portion may include one or more transcutaneous irradiation modules configured to be arranged on a head of a user, the top transcutaneous irradiation modules including a top pulsed laser source. The bottom portion may include one or more transcutaneous irradiation modules configured to be arranged on an abdomen of the user, the top transcutaneous irradiation modules including a bottom pulsed laser source. A modulation frequency may be applied to the top and bottom irradiation modules such that the top and bottom pulse laser sources are subjected to a double pulse.

Abstract: The invention relates mainly to an optical guide for diffusing a light radiation through a surface, which is essentially characterized in that it includes a base (3,31) comprising or able to hold at least one diffusion rod (2, 2a; 35a, 35b, 35c) whose lower diffusion end (7, 7a; 38a, 38b, 38c) protrudes from said base (3) and is intended to be applied on or near said surface, and whose upper collecting end (6,6a; 37a, 37b, 37c) is intended to be located near and opposite a power supplied light source (36a, 36b, 36c), and in that the diffusion rod (2, 2a; 35a, 35b, 35c) comprises a material able to transmit light from its collecting end (6,6a; 37a, 37b, 37c) up to its diffusion end (7, 7a; 38a, 38b, 38c). The invention also relates to an irradiation module and to an irradiation device adapted to the transcranial and/or transcutaneous irradiation by light radiation.

Abstract: In the context of management of handover roaming, a communication system comprises a first LPWAN network of a first operator and a second LPWAN network of a second operator. The first network comprises gathering gateways, a first server managing the gathering gateways, and a second server controlling the MAC layer. The second network comprises a third server interfacing fourth and fifth servers with the second server. Uplink frames of application data are transported from an end device of the second operator to the fourth server by successive relayings of the first, second and third servers. However, when the end device of the second operator requests joining the communication system in order to benefit from the services of the fourth server, the gathering gateways communicate with the fifth server, short-circuiting the first, second and third servers.

Abstract: A communication system comprises a first LPWAN network of a first operator and a second LPWAN network of a second operator. The first network comprises subnetworks implementing separate respective transport protocols. The subnetworks comprise at least one convergence node and communication nodes integrating gathering gateways. The first network comprises servers interconnected to a server of the second network interfacing an application server and an authentication server. Uplink frames of application data are transported from an end device of the second operator to the application server by successive relayings of the servers. However, when the end device of the second operator requests to join the communication system in order to benefit from the services of the application server, the gathering gateways communicate directly with the authentication server by shortcutting the other servers as well as the convergence nodes to which said gathering gateways are respectively attached.

Abstract: Novel ultra-thin unidirectional pre-preg tapes are disclosed. They can be used to produce ultra-thin woven, bias, multiaxial, chopped-oriented etc. types of pre-pregs. These ultra-thin pre-pregs enable production of composite material products with well-controlled dimensional tolerances and smooth/even surfaces. Further, they render the production of composite material products relatively simpler, tidier, quicker, and economical. The obtained composite material products are relatively thinner, lighter, and mechanically higher-performing.

Abstract: The invention relates to a transcutaneous irradiation device which is essentially characterised in that it comprises: a top portion (1) suitable for positioning on the head (3) of a user and comprising at least one transcutaneous irradiation module (10) consisting of at least one irradiation source, and a bottom portion (9) suitable for being positioned on the abdomen (16) of the user and comprising at least one transcutaneous irradiation module (10) consisting of at least one irradiation source. In particular, the transcutaneous irradiation device of the invention is configured for the prevention or treatment of neurological disorders and/or neurodegenerative diseases, preferably for the prevention or treatment of Alzheimer's disease, Parkinson's disease and/or Huntington's disease.
