  • Publication number: 20170225452
    Abstract: A dampening fluid useful in offset ink printing applications contains water and a surfactant whose structure can be altered. The alteration in structure aids in reducing accumulation of the surfactant on the surface of an imaging member. The surfactant can be decomposed, switched between cis-trans states, or polymerizable with ink that is subsequently placed on the surface.

  • Publication number: 20170097612
    Abstract: An elapsed timer device includes a timer element comprising a timer chamber, a timer chamber conditioning material disposed within the timer chamber, and a sensor arranged to sense a timer chemical within the timer chamber. The sensor indicates elapsed time in response to a threshold level of the chemical being present within the timer chamber. The timer chamber, timer chemical adsorption/desorption characteristics of the timer chamber conditioning material, and the sensor are configured so that an amount of the timer chemical within the timer chamber reaches the threshold level within a predetermined time after initialization of the timer element.

  • Publication number: 20170071521
    Abstract: What is disclosed is a system and method for representing a subject's state of mind given a plurality of physiological inputs. In one embodiment, a vector of physiological features is received. The vector of physiological features is provided to a psychophysiological model which comprises a plurality of models which fit the physiological features to psychological quantities, each representing a different state of mind. In a manner more fully disclosed herein, the psychological quantities are then aggregated to obtain an aggregate output that is representative of the subject's overall state of mind. Once the subject's state of mind has been represented, remedial action can then be taken.

  • Publication number: 20170049374
    Abstract: A method and system for generating a personalized health management recommendation for a user. During operation, the system obtains first physiological data generated by a wearable device worn by the user that indicates a physiological condition of the user. The system then generates a prediction model for the user based on the first physiological data. Next, the system obtains real-time physiological data generated by the wearable device. The system may generate a prediction by analyzing the real-time physiological data to determine whether the user's physiological condition exceeds a threshold parameter according to the prediction model. Upon determining that the threshold parameter has been exceeded, the system may select a recommendation and send the recommendation message to the user's mobile device.

  • Patent number: 9021948
    Abstract: Methods and structures are disclosed to minimize the presence of vapor clouding in the path between an energy (e.g., radiation) source and the dampening fluid layer in a variable data lithography system. Also disclosed are conditions for optimizing vaporization of regions of the dampening fluid layer for a given laser source power. Conditions are also disclosed for minimizing re-condensation of vaporized dampening fluid onto the patterned dampening fluid layer. Accordingly, a reduction in the power required for, and an increase in the reproducibility of, patterning of a dampening fluid layer over a reimageable surface in a variable data lithography system are disclosed.
