  • Publication number: 20190255247
    Abstract: A pump system is disclosed that comprises a control unit and one or more modular pumping units removably docked to the primary control unit. Each modular pumping unit comprises a pumping mechanism and a processor configured to control the pumping mechanism and communicate with the control unit. The modular pumping unit is configured to manipulate a portion of a fluid delivery set to pump a fluid. The first processor and the second processor are configured to exchange one or more operating parameters when the modular pumping unit is docked to the primary control unit. The modular pumping unit is configured to pump the fluid after being undocked.

  • Patent number: 10347375
    Abstract: A system and method of associating a plurality of objects is disclosed. A physical space may be defined and a real-time locating system (RTLS) may be used to determine objects that are within the physical space. The objects may be determined by the RTLS to be within the physical space are associated. The objects may include at least one of a caregiver, a patient, a medical device, a medication, and a medical substance.

  • Patent number: 10188792
    Abstract: A method of infusing a fluid includes receiving values of one or more infusion parameters for an infusion of a fluid, Based on the received infusion parameter values, an occlusion pressure threshold for the infusion of the fluid is automatically calculated. During the infusion, a fluid pressure value is sensed. An indication is provided responsive to whether a value of the sensed fluid pressure is greater than the occlusion pressure threshold.

  • Publication number: 20180041722
    Abstract: A regulated supply voltage can be established using switching cycles defined at least in part according to a switching clock period. Imaging information can be acquired from an imaging sensor and a discrete-time representation of the imaging information can be received. Noise, such as corresponding to the switching cycles, can be reduced or suppressed. In an example, a discrete-valued noise template can be stored in a memory, wherein a count of values in the noise template is less than a count of an entirety of a physical row of pixels from the imaging sensor. The discrete-valued noise template can be aligned with a portion of the discrete-time representation of the imaging information. The noise in the discrete-time representation can be at least partially canceled using the aligned discrete-valued noise template. The template can be constructed such as by aggregating imaging information obtained from an optically-black portion of the imaging sensor.
