  • Patent number: 11196418
    Abstract: Apparatus and associated methods relate to an I/O bank impedance calibration circuit having (a) a replica master resistor coupled to an external precision resistor, and (b) a control circuit configured to calibrate an output impedance of the master resistor to generate a calibrated code to control a replica slave resistor in each bank. In an illustrative example, a signal applied to the replica master resistor may be compared against a programmable reference signal. The control circuit may generate the calibrated code, in response to the comparison result, to calibrate the output impedance of the replica master resistor. By implementing the replica master resistor and the replica slave resistor, impedances of a large number of IOs or banks may be calibrated by the impedance calibration circuit using a single one reference pin.

  • Publication number: 20190353621
    Abstract: A crack detecting system includes a tool movable along a conduit or structure and having at least one sensing device for sensing cracks in a wall of the conduit or structure. The sensing device includes a fluid emitter and the fluid emitter includes at least one orifice configured to emit fluid. In response to the orifice emitting fluid, the emitted fluid excites the conduit or structure and the sensing device senses a response from the excitation of the conduit or structure. A processor is operable to process the response sensed by the sensing device and responsive to the processing, the processor determines flaws present at the wall of the conduit or structure.

  • Patent number: 10343448
    Abstract: A paint tray liner bag can fully encapsulate a rigid paint tray and fully form to the shape of the rigid paint tray. The paint tray liner bag includes a bag flap that folds over to the bottom of the rigid paint tray and has holes to receive the legs of the rigid paint tray, thereby securing the paint tray liner bag on the rigid paint tray. Unlike rigid paint trays, that do not fit well into sinks and have ridges that can be difficult to clean, the paint tray liner bag can be removed from the rigid paint tray and easily cleaned due to its smooth surface and flexibility to fit into a user's sink.

  • Patent number: 10077146
    Abstract: A tie well-suited for use in retail packaging applications includes a plastic head insert molded around one end of a paper-based cord, such as a length of twine, string or other similar environmentally-friendly material. In one embodiment, the plastic head includes a generally rectangular buckle shaped to define an elongated channel dimensioned to receive the free end of the paper-based cord. A deflectable pawl is coupled to the buckle and is naturally biased to project into the channel and selectively engage the cord in order to retain the tie in a closed loop configuration. The buckle includes a substantially open side wall through which the paper-based cord can be extracted after the tie is formed in its closed loop configuration. A clip is preferably provided on the head for selectively retaining a section of the paper-cord that has been inserted through the elongated channel.

  • Patent number: 9212968
    Abstract: A calibration device for a radiometer includes an integrating cavity and a honeycomb blackbody mounted to the integrating cavity. A plurality of emitters are mounted to the exterior rim of the integrating cavity for transmitting narrow band wavelengths of light into and out of the integrating cavity. A controller, selectively, activates one or more emitters to radiate a single narrow band wavelength of light during an ON period and turn OFF during another period. A plurality of reference detectors are also mounted to the exterior rim of the integrating cavity for measuring the intensity of each narrow band radiation outputted from the integrating cavity. The reference detectors are effective in determining changes in intensity output by each of the narrow band emitters from the integrating cavity. The measured changes in intensity outputted by the emitters are used to calibrate the radiometer with the changes traced back to a NIST standard.
