  • Patent number: 11039531
    Abstract: An In-Mold Electronics (IME) device and method of manufacturing the IME device introduce a stretchable substrate laminated to a thermoplastic layer. The stretchable substrate has a screen printable surface for receiving printed conductive interconnects. This combination enables formation of an IME device with conductive interconnects oriented for hard to reach cavities and areas. The IME device eliminates the need to have additional mold features to enable deeper drawn cavities.

  • Publication number: 20210176857
    Abstract: Methods, devices, and systems for producing a flexible electronic device that reduces stress and forces on electronic components are provided. In particular, one or more transition layers with intermediate flexibility, or flexural modulus, are positioned between rigid components and flexible outer layers. This gradually reduces the flexural modulus of the flexible electronics device rather than have an interface between a rigid material and a flexible material. Various materials and methods of forming the layers are described. In addition, an encapsulate layer can be cured to varying flexural moduli to gradually reduce the flexural moduli from the rigid component to the flexible outer layers or bulk structure of the flexible electronic device.

  • Patent number: 11022580
    Abstract: A PCB based electrochemical sensor includes a PCB having a first electrode on a first surface of the PCB, and a second electrode on a second surface. A sensing element, such as a conductive wire, is attached to the first electrode. The PCB includes one or more through holes, and the conductive wire is positioned proximate one or more of the one or more through holes. When the PCB based electrochemical sensor is positioned in a solution to be sensed, the solution fills the through holes. The ions within the solution provide a current pathway between the conductive wire and the second electrode through the through holes. A voltage potential between the two electrodes is measured. The measured voltage potential is used to determine a value associated with the solution, such as a pH value.

  • Patent number: 11004591
    Abstract: A power conversion circuit has a multilayer transformer and a plurality of rectifying transistors coupled to the secondary windings of the multilayer transformer. The multilayer transformer is formed as multiple layers within a PCB stack, where primary winding conductors and secondary winding conductors are vertically aligned and stacked. The secondary winding conductors are constructed to have one or more secondary winding arms that provide area to which the plurality of rectifying transistors are physically connected. The primary winding conductors are constructed to have a primary winding arm. A footprint of each primary winding conductor is configured to substantially overlap an entire footprint of each of the secondary winding conductors. As such, an entirety of the secondary current flowing through the secondary winding conductors is vertically aligned with the primary winding conductors, and therefore with the primary current flowing through the secondary winding conductors.

  • Patent number: 10965009
    Abstract: The methods, systems, and devices of the present disclosure are directed to a capacitively coupled label antenna as a component in an antenna system comprising the label antenna, a feed block, an antenna coupler, and a gap between the antenna coupler and the feed block. The label antenna is electrically connected to the antenna coupler, and the antenna coupler is capacitively coupled to the feed block through the gap. By the addition of the gap between the feed block and antenna coupler, the label antenna may be placed on the surface of a container without requiring a wired connection to pass through the container. The feed block may be a small electronic component on a circuit board while the label antenna may be significantly larger thereby providing increased frequency bandwidth and an improved antenna radiation pattern.

The substrate surface includes a specific mounting location to which an electronic component is to be electrically connected, where each specific mounting location includes one or more electrical connection points, such as contact pads. An anisotropic conductive film (ACF) is applied to the substrate surface covering the one or more electrical connection points of the specific mounting location, and the electronic component is placed on the ACF and properly aligned with the specific mounting location on the substrate surface. Pressure and heat are applied to compress the ACF to form an electrical interconnection between corresponding pairs of the electrical connection points on the electronic device and the specific mounting location on the substrate surface.

  • Patent number: 10917001
    Abstract: A resonant power converter has a main switch, a resonant tank coupled across the main switch, and a signal processing circuit coupled to the main switch and the resonant tank. The signal processing circuit generates a driving signal for driving the main switch ON and OFF at a switching frequency. The resonant tank includes circuit components designed to have a resonant frequency that is tuned to a designed switching frequency of the main switch. The signal processing circuit includes a zero voltage switching (ZVS) circuit, a signal generator, a detection circuit, and a latch oscillator. The signal processing circuit is configured to adjust the switching frequency of the driving signal to be tuned to the actual resonant frequency of a resonant tank under very high switching frequency conditions, 1 MHz and greater, thereby accounting for the influence of parasitics at very high switching frequencies and achieving resonance of the circuit.

  • Patent number: 10905821
    Abstract: A system and method for calibrating an IV pump infusion system tube comprises a fluid source, an infusion system comprising, an IV pump, a drive unit, a chamber with known constant volume, a control unit, and IV tubing with a known inner diameter tolerance, and a set of conductive plates. The system administers medicinal fluid, calculates the flow rate of the medicinal fluid in the chamber by measuring the time the capacitance level of the medicinal fluid changes from a capacitance level corresponding to a first (initial) position to a capacitance level corresponding to a second (filled) position, compares the calculated flow rate with a set flow rate of the IV pump input in the control unit prior to infusion, and adjusts the IV pump and flow rate based on the compared deviations for more accurate delivery to a patient. This configuration may therefore provide a more precise delivery rate.
