  • Patent number: 9925305
    Abstract: An apparatus and method for hydrating a particulate biomaterial with a liquid biomaterial includes a vacuum device and a valve for withdrawing a gas from the particulate biomaterial and introducing the liquid biomaterial. The valve includes a hub, a valve body, a particulate port, a vacuum port, and a liquid port. The valve body selectively moves between first and second positions. The valve body at least partially defines a first passage and a second passage. The particulate port, the vacuum port, and the liquid port are each configured to fluidly connect to a particulate container, the vacuum device, and the liquid container, respectively. In the first position, the first passage fluidly connects the vacuum port to the particulate port for withdrawing the gas from the particulate container. In the second position, the second passage fluidly connects the liquid port to the particulate port for hydrating the particulate biomaterial.

  • Patent number: 9482150
    Abstract: A method for controlling a heat recovery device in an internal combustion engine, in particular, for a motor vehicle. The heat recovery device is provided with a circuit for a working medium having an evaporator of an expansion machine that is arranged in an exhaust gas flow path of the internal combustion engine, a condensor, an expansion tank, and a feed pump. The working temperature of the working medium is controlled by varying the mass flow of the working fluid as a function of at least one operating parameter. A setpoint value of the working medium mass flow of an exhaust gas flow path of an exhaust gas tract and/or an exhaust gas recirculation line is calculated on the basis of a base setpoint value for the working medium mass flow. The base setpoint value for the working medium mass flow is at least a function of the exhaust gas temperature, preferably upstream of the evaporator, and of the exhaust gas mass flow in the exhaust gas flow path.

  • Patent number: 9384329
    Abstract: A system and method is disclosed determining caloric burn via an HCI system. Using a capture device which is able to detect the thickness of a user's arms, legs, torso, etc., the system determines a mass for each of a user's body parts. Thereafter, in one example, the system measures caloric burn for a given body part as a function of how far the body part was displaced, a mass of the body part displaced and gravity.
