  • Patent number: 9951767
    Abstract: A vibrational fluid mover includes a housing having at least one actuator element positioned thereon that vibrates responsive to a wave shape voltage applied thereto, such that a volume of a chamber in the housing increases and decreases to entrain and eject fluid into/out from the chamber. A control system is operably connected to the actuator element to cause the voltage to be provided thereto so as to actively control the movement of the actuator element. The control system is programmed to set a baseline value for an operational parameter of the vibrational fluid mover generated responsive to a target voltage and frequency being provided, monitor operation of the vibrational fluid mover during operation at the target voltage and frequency, identify a deviation of the operational parameter from the baseline value, and modify the voltage and frequency provided to the actuator element based on any deviation of the operational parameter.

  • Patent number: 9812374
    Abstract: Methods and apparatus are described for heat management in an integrated circuit (IC) package using a device with a textured surface having multiple grooves in an otherwise relatively flat surface. The textured surface of the heat management device is designed, in conjunction with a thermal interface material (TIM), to push gas bubbles out of the flat areas such that the gas bubbles are trapped in the grooves or driven out of the interface between the device and the TIM altogether. The area of the grooves is small relative to the ungrooved areas (i.e., the flat areas), such that when the gas bubbles are trapped in the grooved areas, the ungrooved areas work even better for heat transfer. With the area of the regions for the flat portions being substantially greater than the area of the regions for the grooves, the textured heat management device is designed to lower thermal resistance, increase thermal conductivity, and increase heat transfer from one or more IC dies to a heat sink assembly in an IC package.

  • Publication number: 20170089874
    Abstract: There are provided methods and devices for sensing hydrogen gas. For example, there is provided a method that includes drawing a sample into a channel. The method includes passing the sample over a collection plate to remove an extraneous gas in the sample, thus yielding a purified sample. The method further includes passing the purified sample on a sensing plate and measuring a concentration of hydrogen in the purified sample using the sensing plate. The measuring can include heating the sensing plate and correlating a change in resistance of the sensing plate with a specified concentration of hydrogen. Furthermore, the method can include regenerating the collection plate following the measuring.
