Abstract: A system is provided which, in at least some embodiments, can read the vital signs of the body of a user utilizing a sensing device such as a smartwatch or smart phone (for example utilizing the iOS, Android or Pebble operating systems) and apply algorithms to interpret the vital signs and then send a notification with an escalation process to nominated carriers if the patient interpreted as having a fall or fit or seizure. In at least some embodiments doctors or other parties can log in to a secured dashboard and check a patient data in real time. Doctors or other parties can analyze the history of the patient. In at least some embodiments, users/patients can also use data to keep track of fall or fit or seizure episodes and monitor their progress.

Abstract: A system is provided which, in at least some embodiments, can read the vital signs of the body of a user utilising a sensing device such as a smartwatch or smart phone (for example utilising the iOS, Android or Pebble operating systems) and apply algorithms to interpret the vital signs and then send a notification with an escalation process to nominated carers if the patient is interpreted as having a fall or fit or seizure. In at least some embodiments doctors or other parties can log in to a secured dashboard and check a patient data in real time. Also in at least some preferred forms doctors or other parties can analyse the history of the patient. In at least some embodiments users/patients can also use data to keep track of fall or fit or seizure episodes and monitor their progress. Embodiments of the invention can be applied for example in situations where the patient/user suffers from a medical condition such as epilepsy and which may predispose the patient/user to falls and related events.

Abstract: A process for obtaining a solid form containing heat-stabilized borazane is described. The solid form is capable of generating hydrogen by thermal decomposition or by a self-maintained combustion reaction. Within the solid form containing borazane, the borazane is heat-stabilized. It has thus been heat-stabilized by making an oxidized layer at its surface.

Abstract: The main subjects of the present invention are: a process for obtaining a solid composite propellant (with a polyurethane binder filled with ammonium perchlorate and with aluminum): characteristically, the ammonium perchlorate charge of said propellant is obtained from at least two charges each having a specific monomodal particle size distribution. It is thus sought to reduce the thrust oscillations and the alumina deposits at the back of the engine; a solid composite propellant, the solid propellant charges and the associated rocket engines.

Abstract: The present invention provides pyrotechnic grains of composition comprising at least one oxidizing charge and at least one reducing charge and no binder. In characteristic manner, said grains are in the form of substantially cylindrical blocks: with a thickness of more than 5 mm; with an equivalent diameter of 10 mm or more; and with porosity in the range 1% to 8%, limits included. Said grains, advantageously based on guanidine nitrate and basic copper nitrate, are suitable for the slow, low-pressure generation of gas over an extended period.
