  • Publication number: 20220252660
    Abstract: The present invention provides a method for detecting failed back-drills in PCBs in the process of fabricating a PCB so that the failed back-drill can be screened out or repaired. The present invention accomplishes this by adding a short to ground connection for every back-drill via that will be cut when the back-drill removes the via stub. If the back-drill is bad or failed the short to ground will fail the subsequent electrical tests. The PCB can be repaired by re-drilling the hole or via. The present invention allows for detecting failed back-drills with easy detection in the manufacturing stage using standard equipment and test procedures. This process creates a simple pass-fail measurement that uses an existing common test process to catch failed back drills in the PCB fabrication facility. This allows for easy and cost-effective repair and guarantees back-drill failures do not pass into the field.

  • Patent number: 11063397
    Abstract: A flush ring spacer, and method for using it, to adjustably support and firmly mount an electrical device, such as an electrical receptacle or switch, within a wall or other support surface. Using the present invention, electrical devices may be connected to 1,900 (4-square), gem or other electrical boxes, while remaining firmly flush to the wall or other surface. The electrical device will stay grounded and not move or push in (which can affect grounding), and the face plate will not crack and will no longer be used to support the electrical device.

  • Publication number: 20190329196
    Abstract: A method of mixing a pharmaceutical solution including adding a gas into an interior compartment of a mix bag to form a headspace. The interior compartment of the mix bag includes a top portion and a bottom portion. The headspace adjacent to the top portion contains gas. The method includes adding a solvent into the mix bag, and establishing a bubble column in the interior compartment by activating a recirculation assembly. The recirculation assembly includes a connecting pathway operably coupled to a recirculation pump. A first end of the connecting pathway is coupled to a top gas recirculation port and a second end is coupled to a bottom gas recirculation port of the mix bag such that the recirculation pump draws the gas from the headspace and delivers the gas to the interior compartment via the bottom gas recirculation port. The method includes adding a solute into the mix bag.

  • Patent number: 10344615
    Abstract: A method and system of scheduling a demand for a process inner loop are provided. The loop controller includes an inner loop control system configured to generate a control output signal for a controllable member and a schedule demand module configured to receive parameter values for a controlled variable of a process from a parameter source and to generate a scheduled demand output using a demand schedule. The loop controller also includes a schedule prediction module configured to predict a future value of a scheduling parameter based on a historical performance of the inner loop control system and current system dynamics and to generate a scheduled rate output. The schedule prediction module includes the rate-of-change of a scheduling parameter and a lead time input that defines a look-ahead time period used with the parameter rate signal to determine a future predicted value of the controlled variable.
