Title: Procede de tracage de quantites de substances chimiques utilisant des colorants fluorescents encapsules
Inventor: XIAO LAN
IPC: G01N21/77
Filed: 2014-08-04
Abstract: L'invention porte sur des procédés et des compositions pour utiliser des colorants de traceurs encapsulés dans des liquides complexes tels que les eaux usées ou avec des substances chimiques hautement réactives pour le traitement comme des coagulants à base d'aluminium. Dans les liquides complexes ou les substances chimiques hautement réactives pour le traitement, même les traceurs soit-disant inertes finissent par réagir et leur fluorescence change. Par conséquent, ils manquent de cohérence et ils ne peuvent pas être utilisés pour mesurer la quantité de substance chimique de traitement présente. Mais en encapsulant les colorants traceurs, même les colorants traceurs non inertes deviennent inertes et peuvent être utilisé de manière fiable pour mesurer la quantité de substance chimique de traitement présente même en cas de haute réactivité ou dans un liquide complexe.

Title: Unlocking mechanism for disabled portable computing devices using quick response code
Inventor: RODRIGS JERI
IPC: G06F9/06
Filed: 2016-02-08
Abstract: Mechanism to unlock disabled portable computing devices using Quick Response (QR) code. The portable computing devices can be in disabled mode due to various reasons like the user can be in driving mode or not in a position to safely operate the device. Unlocking of the device is warranted in some situations, for example the passenger travelling in the same vehicle need to use their portable computing devices. Unlocking portable computing devices mechanism uses the existing utilities already available in the portable computing devices such as camera and finger print scanner. Embodiments of this invention relate to unlocking mechanism using Quick Response code need at least one other portable computing device to unlock a disabled device. One device is used to generate and display the QR code for the other device to scan the QR  code and get unlocked. This measure is implemented so that driver engaged in driving cannot unlock the phone by self.
