  • Patent number: 10042847
    Abstract: A method, system and computer program product for enabling attendees of a web conference to view materials of the web conference in their native language. When the conference server determines that the preferred native language of the attendee differs from the preferred native language of the presenter of the web conference, the conference server creates a virtual environment that is a clone of a host environment of the presenter that runs a native language pack of the preferred native language of the attendee. Upon the presenter starting the web conference, the screen shot shared by the presenter to the attendees is captured from the host environment of the presenter and then translated into the preferred native language of the attendee using the native language pack of the attendee's virtual environment. The translated screen shot is then sent to the attendee in the attendee's preferred native language from the virtual environment.

  • Patent number: 10023178
    Abstract: A method of variably controlling a transmission pattern of a hybrid vehicle is provided. The method converts a transmission pattern into a pattern that sufficiently secures engine charge power by considering the total amount of electric load when the transmission pattern is determined based on a current SOC state. The method variably controls the transmission pattern of a hybrid vehicle to prevent a battery SOC excessive decrease due to an increase of electric load of a vehicle by reflecting and compensating for the used amount of electric load of a hybrid vehicle when the type of transmission pattern is determined. Also, fuel efficiency is improved based on the improvement of battery charge efficiency by determining the transmission pattern such that the speed of a transmission input terminal increases when the electric load increases and thus securing the engine charge power for the battery charge.
