  • Publication number: 20210222444
    Abstract: Anchors, clutches, and lifting systems are described herein that increase the size of a shear cone within a precast concrete panel without using multiple clutches and without increasing the complexity of the lift system. A shear cone is the volume within the panel that the anchor and clutch pull on when orienting and positioning the precast concrete panel. Anchors described herein encompass a larger volume of the panel in different ways to produce a larger shear cone. Similarly, the clutches described herein have features that allow a clutch to accommodate the improved anchors. As a result, the anchors, clutches, and lifting systems provide a larger shear cone in the panel to increase the load capacity of the lifting system and reduce the likelihood of failure.

  • Patent number: 11018964
    Abstract: An apparatus and method that captures a complete history of serial network Link Training negotiations by continuously monitoring multiple analog signals representing both sides of full duplex lanes in real-time by pattern matching the Link Training Frame Marker and the subsequent negotiation request/response data values. The apparatus and method compare the digitized version of the incoming signal against a nominal pattern at the start to find the Frame Markers and Control Channel data, storing only those Control Channel data values that do not match the current compare pattern, and further by updating the current compare pattern to the new pattern just received, so that only the transitions in the data values are stored, thereby vastly reducing the amount of data presented to the user, but nonetheless retaining the complete substantive history of the Link Training negotiations.

  • Publication number: 20190383045
    Abstract: Composite precast concrete panels are described herein having have an anchor that distributes forces imposed on the anchor through concrete wythes of the panels. Specifically, pins can be embedded in at least one concrete wythe, and then the anchor is secured to the wythe as described herein. The anchor extends through another Wythe to selectively connect to a hoist system that moves and places the composite precast concrete panel. The forces imposed on the anchor are distributed through the pins and into multiple concrete wythes to prevent failure of the composite precast concrete panels and improve safety.

  • Patent number: 10481179
    Abstract: A test and measurement instrument including an input port configured to receive an input signal. One or more divider circuits, coupled to the input port, employ a plurality of divide ratios such that each divide ratio scales an event signal indicating events in the input signal by a predetermined integer value. A control system is also included. The control system is configured to iteratively determine an estimated signal frequency of the event signal, and automatically select a divide ratio for the event signal based on the estimated signal frequency. The instrument may also include one or more counters to count triggers in the event signal subsequent to application of the divide ratio. The instrument may also employ frequency hysteresis to prevent chatter in divide ratio selection.

  • Patent number: 10365300
    Abstract: This disclosure relates generally to test and measurement instruments structured to detect that a series of events occurred, and structured to generate a trigger signal in response to detecting that a final event in the series of events occurred. The trigger may be generated based on a timeout signal, or based on another event, trigger, or signal. Stored data in the acquisition memory may be marked relative to the detection of the final event. An external forced timeout signal may control which in a series of events is marked as a final event. The triggering on final event may be enabled after another trigger is satisfied, and may be used as one of many different types of triggers.

  • Patent number: 9934355
    Abstract: A test and measurement apparatus, system, and method for synchronizing an acquisition or triggering system to a specific burst of interest. The subject apparatus and method triggers on varying energy content of a signal qualified by time in the presence of high-frequency input signal bursts, by using an adjustable pulse width envelope detector, disposed in the signal path of the trigger circuitry, as a digital rectifier or to otherwise process and extract an envelope signal. An RF envelope probe having an analog envelope detector among other suitable components is disclosed. A method is implemented for isolating an interval of interest in a signal under test. An envelope detector circuit produces an envelope signal from the signal. Trigger circuitry receives the envelope signal from the envelope detector, and isolates the interval of interesting in the signal under test using the envelope signal.

  • Patent number: 9207263
    Abstract: A test and measurement instrument includes an input terminal to receive a signal, acquisition circuitry to capture a plurality of triggered acquisitions, trigger circuitry to cause a trigger event responsive to trigger criteria, and a controller to dynamically reconfigure the trigger criteria between triggered acquisitions. The controller is configured to dynamically reconfigure the trigger criteria from the first set of trigger criteria to subsequent sets of trigger criteria between each of the triggered acquisitions. A method is disclosed for scanning information associated with an initial triggered acquisition and, depending on the nature of the scanned information, dynamically adjusting the next or any subsequent set of trigger criteria.

  • Publication number: 20150029330
    Abstract: In a control unit of an electronic component mounting apparatus, when an imaging form of a component imaging unit is set to a first mode, a component recognition unit recognizes a first electronic component based on an imaged image due to a first imaging element of the component imaging unit, and recognizes a second electronic component based on an imaged image due to a second imaging element of the component imaging unit. Meanwhile, when the imaging form is set to a second mode, the component recognition unit recognizes the electronic components based on an image in which the imaged image by the first imaging element is combined with the imaged image by the second imaging element.
