  • Publication number: 20240409897
    Abstract: The invention features a method of producing aggregates of a plurality of cell populations (e.g., a first population of cells and a second population of cells). The method includes agitating a liquid medium that contains the cells in a bioreactor. These aggregates may be used for subsequent downstream applications, such as encapsulation in a biocompatible scaffold to form an engineered tissue construct.

  • Patent number: 10767618
    Abstract: A submerged wave energy conversion apparatus and pressurized fluid or electricity production system are provided that harvests energy from a motive force derived from pressure differentials created by the interaction of the system with ocean water. The system is capable of capturing energy from up to six different modes of motion of the absorber body in response to the energy of incident waves. The apparatus has an absorber body that is attached to one or more damping mechanisms like a hydraulic cylinder, a hydraulic circuit that can create useful mechanical torque, a restoring mechanism such as an air spring to restore the absorber system to stable equilibrium, and a buoyant artificial floor to create an opposing reaction force. The apparatus may also have a controller for system monitoring and control, to maintain optimized energy extraction, and for load management to avoid damaging loads.

  • Patent number: 9777701
    Abstract: A carpet of wave energy conversion (CWEC) device mechanically couples an absorber carpet to one or more energy converters, thereby allowing for wave energy extraction from passing waves. The absorber carpet may be flexible material of a composite material that has a low elastic modulus in a longitudinal direction (to allow for stretching), and a relatively higher elastic modulus in a transverse direction (to better couple energy from wave to converters). Such designs have minimal wave reflections and high efficiencies within a relatively short extent of deployment. The resultant converted useful energy is available as either: 1) mechanical power including direct desalinization or electrical production; or 2) hydraulic power for a number of applications (including hydraulically powered motors supplying power to powered devices including generators), or pumping of the wave medium under pressure to an alternate location for irrigation or energy storage.

  • Publication number: 20130090814
    Abstract: A method to determine at least one triggering parameter of personal protection device of a vehicle using pattern signal curves of a possible signal of a sensor for a physical variable. The pattern signal curves replicating a curve over time of the physical variable upon impact of an object on the vehicle at a different location on the vehicle and/or upon impact of the object on the vehicle at a different angle. A sensor signal is read which represents the physical variable measured by a sensor. Values of a curve over time of the sensor signal are compared to values of the at least two pattern signal curves, that pattern signal curve being selected which, in at least one time segment of the pattern signal curve or one scaled form of the pattern signal curve has a lower deviation from the curve over time of the sensor signal.
