Cascading Effect. A “cascading effect” is a potentially significant and sometimes unforeseen sequence of events that affects a system or system-of-systems. Unlike the impact that may be created within a system’s topography by cutting or destroying individual links and nodes, a cascading effect may be initiated by seemingly minor events...

CAN-bus-based network management method and system

The embodiment of the invention provides a CAN (Controller Area Network)-bus-based network management method and system. The CAN-bus-based network management method is applied to each target node in the same CAN network. The CAN-bus-based network management method includes the steps: acquiring the target network state of target nodes, wherein the network state at least includes a dormant state anda wake-up state; and when the target network state is in the dormant state, determining whether the target nodes meet the preset wake-up conditions, wherein if so, the target network state of the corresponding target node jumps to the wake-up state, and if not, the target network state of the corresponding target node remains in the dormant state. When the CAN-bus-based network management methodis used to perform network management, each node in the network is executed according to the above scheme, and no cascading effect exists between each node. Therefore, each node can be in the dormantstate or the wake-up state according to the needs of the functional system in which the each node is located, thus reducing unnecessary waste of waiting for the remaining nodes on the network to be inthe dormant state or to wake up by the remaining nodes without performing the corresponding functions.

Apparatus and method for non-destructive, low stress removal of soldered electronic components

Circuit chips, such as known good die (KGD) chips, are removed from an assembly including a plurality of circuit chips attached to at least one chip carrier, or substrate. The substrate is held within a top plate with the circuit chips positioned within successive chip cavities within a bottom plate. Each chip cavity includes a load surface separated by a cascade effect pitch with respect to adjacent chip cavities. A cascade effect shear force is sequentially applied to the circuit chips to remove them from the substrate. The chips may be heated to a temperature facilitating shear within a temperature range at which solder connections are solid, and the chips further heated following disassembly to a temperature at which the solder is liquid to facilitate reforming the solder for subsequent attachment of the chip into an electronic device.

Phase-alternating mixer with alias and harmonic rejection

Rejection of local oscillator alias response is provided in a mixing circuit by (1) a switching mixer producing an output that changes at least twice between two states (e.g., high-low-high or low-high-low) during each local oscillator period, and (2) a charge integrator integrating current output from the switching mixer over the local oscillator period. The switching mixer and charge integrator produce a sampled data format, double sideband signal with serial cancellation of the switching mixer's alias responses. An extension unit connected in series with the switching mixer and charge integrator, and implementing a transform function computing a difference between consecutive samples, produces a cascading effect with the switching mixer and charge integrator, optionally producing additional nulls suppressing alias response at frequencies near the local oscillator frequency. A harmonic gating circuit between the switching mixer and charge integrator, controlled at a multiple of the local oscillator frequency, suppresses harmonic responses of the switching mixer.

Active dose reduction device and method

An active dose radiation device and method decreases the amount of x-rays which may be generated by an x-ray tube following termination of the x-ray exposure. One component of the x-ray system is connected to the device which has a plurality of electronic cells that can be overvoltaged from a first state, where they are less conductive, to a second state, where they are highly conductive. A voltage pulse generator overvoltages a first cell in the plurality of cells at termination of an x-ray exposure. Overvoltaging the first cell causes a cascading effect which eventually overvoltages all of the cells and changes the state of the cells from the first less conductive state to the second highly conductive state. In the second highly conductive state, the cells can conduct current from at least one component of the x-ray system to ground thereby reducing x-rays generated by the x-ray tube and reducing the x-ray dosage from the imaging system after the x-ray exposure has been completed. The plurality of cells automatically reverts to the first state once current passing through the cells decreases below a threshold current level. The plurality of cells are connected to only the anode side 26 or the cathode side 38 of the x-ray imaging device in order to discharge energy from only one side to ground which results in a sufficient decrease in the voltage across the x-ray tube to prevent generation of active dosage of x-rays which may penetrate the patient.

Spray Angle Measurement Apparatus and Method

Direction of material emitted from orifices is directly related to the effectiveness of spray devices to deliver the material to an intended location area. Improper emission direction results in material, such as medication, paint, or fuel, not reaching its intended target and causes cascading effects, such as improper patient dosing, compromised patient relief, waste, poor target coverage, missed target penetration, poor engine performance, and other safety / performance problems. An apparatus for inspecting operation of an orifice according to an example embodiment measures actual material emission direction relative to an expected material emission direction determined as a function of position and orientation of an orifice. The apparatus may confirm whether the emission direction is within an expected emission direction and accepted tolerance range.
