  • Fluidic property determination from fluid impedances
    Patent number: 11467116
    Abstract: In one example in accordance with the present disclosure, a fluid analysis system is described. The fluid analysis system includes a fluidic die. The fluidic die includes a fluid chamber to hold a volume of fluid to be analyzed and an impedance sensor disposed within the fluid chamber. The impedance sensor measures an impedance of the fluid in the fluid chamber. The fluid analysis system also includes an evaluator device electrically coupled to the impedance sensor. The evaluator device determines at least one property of the fluid based on the impedance.
    Type: Grant

  • Automatic management of a power state of a device with network connections
    Patent number: 8185767
    Abstract: Embodiments provide a process and system for automatic management of networked devices based on the state of the network connection. The process automatically manages the power state of a networked computerized device according to a trigger event that corresponds to the state of an attached network connection. The network connection of an attached networked device is monitored for a pre-defined trigger event. Once a trigger event has been observed, the power state of the attached network device is managed to correspond to the trigger event.
