Abstract: A bandgap reference circuit includes a first diode-coupled transistor having a first control terminal and first and second current terminals and a second transistor having a second control terminal and third and fourth current terminals. The second control terminal is coupled to the first control terminal. A third transistor have a third control terminal and fifth and sixth current terminals. A fourth diode-coupled transistor has a fourth control terminal and seventh and eighth current terminals. The fourth control terminal is coupled to the third control terminal. An operational amplifier has a first input, a second input, and an output. The output is coupled to the first current terminal. A first resistor is coupled between the output and the third current terminal. A second resistor is coupled between the sixth and eighth current terminals.

Abstract: Pump assemblies for use with an IV set are described herein. A pump assembly includes a rotatable crank, a piston rod, and a diaphragm assembly. The crank includes a crank profile defining a plurality of lobes. The piston rod includes a first follower and a second follower spaced apart from the first follower. The rotation of the crank relative to the piston rod causes the piston rod to reciprocate relative to the crank. The diaphragm assembly includes a housing and a diaphragm member. The diaphragm member is coupled to the housing and cooperatively defines a volume in fluid communication with the IV set. The diaphragm member is movable between an extended position configured to draw in fluid from the IV set and a contracted position configured to expel fluid into the IV set. The diaphragm member is coupled to the piston rod to reciprocate the diaphragm member.

Abstract: The present invention uses micro and nano segmentation to create targeted digital content, in the form of segment specific static ads, pictures, carousel, mobile new feeds, video, canvas and other ad types. For example, if the motivation for a health change in an individual is for the sake of their family, specific images or video from social media may be effective in tying the rationale for the change to the messaging. This content can then be delivered is static ads, in carousels or other media options. The content is targeted to a specific user using conventional and unconventional social media targeting systems to assist with the creation of custom campaign delivered over social media for the purposes of influencing positive health behavior.
