  • Publication number: 20240361876
    Abstract: A network computer system operates to communicate instructions to a plurality of user devices. The instructions enable each of the plurality of computing devices to participate in a collaborative session where shared content is rendered on a collaborative medium, where the shared content includes graphic representations of the pointer devices of the individual users. The instructions may be further be executed to enable the individual users to modify the graphic representation of the pointer device to include text content specified by that user.

  • Patent number: 9295955
    Abstract: A continuous, semi-continuous or fed-batch mixing apparatus and process for producing and maintaining a consistently mixed substance uses a tubular vessel equipped with a plurality of annular baffles configured to initiate and maintain uniform mixing and efficient dispersion of the substance in the tubular vessel, with a pump to impart unidirectional linear and non-oscillatory motion to the substance in the tubular vessel thereby promoting and maintaining uniform mixing and efficient dispersion of the substance.

  • Publication number: 20140293729
    Abstract: A method and apparatus for applying oscillatory motion to a substance in a vessel to provide improved mixing, in particular to enable different mixing patterns to be applied to a substance in a vessel without “stop, change and start” protocol, has a member and a control means operatively linked such that the movement of the member is determined by a control signal generated by the control means.

  • Patent number: 8407542
    Abstract: A method and circuit are provided for implementing switching factor reduction in Logic Built in Self Test (LBIST) diagnostics, and a design structure on which the subject circuit resides. Switching factor reduction logic is coupled to a Pseudo-Random Pattern Generator (PRPG) providing channel input patterns to a plurality of LBIST channels used for the LBIST diagnostics. The switching factor reduction logic selectively provides controlled channel input patterns for each of the plurality of channels.

  • Publication number: 20120159273
    Abstract: In a test data access system, a shift register is coupled the test data in pin. A first multiplexer is in data communication with the TDI pin and is configured to receive data from the TDI pin and to transmit data to each of the instruments. The first multiplexer is also configured to receive data from a data recirculation bit and to transmit data from the TDI pin to a plurality of instruments when the recirculation bit has a first value and to transmit data to the plurality of instruments from a recirculation line when the recirculation bit has a second value, different from the first value. A second multiplexer is configured to receive data from each of the plurality of instruments and is configured to transmit data from a selected one of the plurality of instruments, selected based on a value of data in the shift register. A first AND gate is configured to generate a gates clock to the shift register. A second AND gate is responsive to the first AND gate, configured to lock the shift register.

  • Publication number: 20100216631
    Abstract: A method and apparatus for fluid-liquid reactions including gas-liquid and liquid-liquid reactions. The method and apparatus is suitable for mixing a fluid phase species and a liquid phase species to facilitate chemical reaction between said phases. The apparatus comprises a reactor vessel with a plurality of orificed plates and flow control means which initiates and maintains uniform mixing and efficient dispersion of a fluid-liquid mixture within the reactor vessel.
