  • Patent number: 10661253
    Abstract: The present invention provides a process for in-situ preparation of metal oxide(s) comprising the step of precipitating a metal salt solution with Fehling's reagent B and glucose at a suitable temperature. The metal oxide(s) prepared according to the present invention can be used for diverse applications including their utility as catalyst(s) in one or more reactions. The present invention further provides a highly selective bi-functional hybrid catalyst for direct conversion of syn-gas to dimethyl ether (DME) and methods of preparation thereof. The one or more metal oxide(s) can be directly obtained from the metal precursors following the method(s) of the present invention instead of metal hydroxides as in conventional known methods, thereby eliminating the necessity of high temperature calcination step(s) and rigorous reduction procedure(s).

  • Patent number: 9594597
    Abstract: Systems and methods described herein provide for automated brokering of a remote connection to a device between entities, including support personnel, work queues and automated support tools. The automated brokering of the remote connection may be based on a work flow or events detecting during service to the remote device. In one example deployment, a centralized service provides support services to multiple customer devices. For each device, the centralized service establishes a remote connection to the device via a remote connectivity tool. Based on the type of work to perform, the centralized service may automatically provide the remote connection to a support automation tool to automatically deliver a local automation service to the device or to a remote support agent to access the device via the remote connection.

  • Patent number: 9529635
    Abstract: Systems and methods of the present solution provide for the delivery of automated services via configurable packages that are selectable on a user interface by a support agent based on entitlement of the user to the services and/or capabilities of the support agent. For example, a centralized service may package a complex set of actions into configurable executable scripts or packages. The centralized service may deliver and execute the packages on the remote device to resolve a customer's issue. The centralized service may provide a user interface for a support agent to select and deliver the package to the remote device. The centralized service may determine whether or not the user is entitled to receive the service or the support agent is qualified to deliver the server represented by the package.

  • Publication number: 20160294621
    Abstract: The present solution provides increases in automation, scalability and efficiency for delivering technical support services to devices. Systems and methods of the present solution provide a hierarchy or layers of automated desktop services with remote technical support services, which may be automated. The present solution provides an on desktop automation support system that detects and automatically remediates problems on a device of the user. If the problem is not fixed or fixable via local automated remediation at the desktop, a centralized service may remotely deliver technical support services to the device in the form of automated support services delivered to the device or remote technical agents connecting remotely with the device. With the combination of local support automation, remote support automation, remote and onsite technicians, the centralized service may deliver a hierarchy or multi-layers of services to any device.
