For example, a leak detector can emit in response to a detected leak, or a flow-rate sensor can emit in response to a detected flow-rate of a liquid, a simulated fan-speed tachometer signal representative of a selected fan speed. At least partially in response to observing a simulated tachometer signal, a controller can issue a system command corresponding to an underlying system condition for which the simulated tachometer signal is a proxy.

  • Patent number: 9804010
    Abstract: There is provided a method of automatically controlling the mass flow rate of a gas through an orifice through which, in use, choked flow is arranged to occur. The method uses an electronic valve located downstream of a gas source, a piezoelectric oscillator in contact with the gas upstream of the orifice and downstream of the electronic valve and a temperature sensor. The method comprises: a) driving the piezoelectric crystal oscillator at a resonant frequency b) measuring the resonant frequency of the piezoelectric oscillator c) measuring the temperature of the gas; and d) controlling the electronic valve in response to the resonant frequency of the piezoelectric oscillator and the temperature of the gas in order to regulate the mass flow rate of gas through said orifice.

  • Patent number: 9670528
    Abstract: A microfluidic device includes an input port for inputting a particle-containing liquidic samples into the device, a retention member, and a pressure actuator. The retention member is in communication with the input port and is configured to spatially separate particles of the particle-containing liquidic sample from a first portion of the liquid of the particle containing fluidic sample. The pressure actuator recombines at least some of the separated particles with a subset of the first portion of the liquid separated from the particles. The device can also include a lysing chamber that receives the particles and liquid from the retention member. The lysing chamber thermally lyses the particles to release contents thereof.

  • Patent number: 9593554
    Abstract: Embodiments of the present disclosure relate to an injection valve with improved pressure regulation and/or improved erosion resistance. One embodiment of the injection valve includes a first stem and a second stem forming a closure mechanism, and a seal member engaging the first stem. The seal between the seal member and the first stem provides a constant sealing surface and enables precise regulation to the opening pressure. The seal member is protected from high pressure differential flow and erosion damage because the seal member is not exposed to the fluid flow when the injection valve switches between an open and a closed positions.
