Abstract: A quick connect assembly includes a connector housing and fluid connectors that fluidly couple an ink assembly and a print assembly. The quick connect assembly also includes conductive connectors that conductively couple hardware circuitry in the ink assembly with hardware circuitry in the print assembly. First and second portions of the connector housing mate with each other to couple the fluid connectors and to couple the conductive connectors. The first and second housing portions mate with each other by rotating the first housing portion and/or the second housing portion relative to the other of the first housing portion and/or the second housing portion.

Abstract: A stump cutter controller and operator presence system includes one or more capacitive sensors in each of the three control levers that control movement of the cutter wheel. A sensor circuit measures changes in the capacitance of the sensors. The controller automatically disengages a drive clutch and applies a brake to the cutter wheel when the controller senses that an operator has left the operating station—which is assumed when the operator has not touched any one of the three control levers of the operator station for a predetermined time. The controller logic is set to allow the clutch to remain engaged during a delay period, of predetermined duration, to permit the operator to move a hand off of one control lever to another control lever. Also, a grace period, of varying duration based on the speed of the cutter wheel, may be provided during which the clutch is reengaged if an operator returns to the controls.

Abstract: The present disclosure provides a device and method that enable the efficient reduction of stumps. In one embodiment the stump removal methods and devices according to the present disclosure allow the operator to have a clear view of the work area during operation, and the ability to move the reduction device through a wide range of motion during operation. In one embodiment, the material reduction tool pivots relative to the chassis in the vertical plane about multiple pivot points. In some embodiments the device includes a retractable auxiliary control panel located at the end of the device opposite the material reduction tool. The control panel enables the operator to direct the movement of the device from the end of the device and thereby enable the device to maneuver through narrow spaces.

Abstract: Firmware of a hand-held device may be updated automatically dependent on the execution status of an update application resident in the memory of the hand-held device. The execution of the update application is abstracted from the user to provide an enhanced user experience.

Abstract: One embodiment of the present disclosure provides a material reduction machine including a clutch configured and arranged to engage and disengage a material reduction tool with an engine based in response to a control unit. The control unit is configured to decelerate the material reduction tool by maintaining the clutch engaged with the engine during an engine speed reduction period. Another embodiment of the present disclosure also provides a method of decelerating a material reduction tool of a material reduction machine. The method includes the steps of maintaining engagement between the material reduction tool and an engine after the engine enters an engine speed reduction mode, and disengaging the material reduction device from the engine before the engine rpm drops below a predetermined level.

Abstract: A method for automatically updating firmware of a hand-held device. To initiate the automatic update, a reset of the hand-held device is detected and an update application is executed. The update application determines whether a flag, indicating a pervious execution of the update application, has been set. If the flag is set, the update application terminates, otherwise, the update application performs an identification test by determining whether a device ID of the device matches a device ID stored in a table of the update application. If the device ID does not match, the update application terminates and the flag is set. If the device ID matches, the update application updates the firmware of the hand-held device, sets the flag, and terminates. In so doing, the firmware of the hand-held device is updated without requiring user intervention or interaction.

Abstract: A method for automatically updating firmware of a hand-held device. To initiate the automatic update, a reset of the hand-held device is detected. Once a reset is detected, an update application is executed, wherein the update application performs the required updating steps. The update application determines whether a flag has been set in a nonvolatile memory area of the hand-held device. The flag is used to indicate a previous execution of the update application. If the flag is set, the update application terminates, otherwise, the update application performs an identification test by determining whether a device ID of the device matches a device ID stored in a table of the update application. If the device ID does not match, the update application terminates and the flag is set. If the device ID matches, the update application updates the firmware of the hand-held device, sets the flag, and terminates.

Abstract: Tracing a short as a shortest path of explicit VLSI design component instances between two VLSI design component instances with different net names in a hierarchical design is a non-hierarchical problem. The method described in this document computes a shortest path of VLSI design leaf component instances containing at least one of the leaf design components causing the sort. To avoid exceeding available storage, the non-hierarchical instance information maintained during the process is pruned optimally. To achieve feasible performance, two methods to find “good” starting points are provided, based on geometrical distribution or based on connectivity information from the net build (if available).

Abstract: Tracing a short as a shortest path of explicit Very Large Scale Integrated (VLSI) circuit design component instances between two VLSI design component instances with different net names in a hierarchical design is a non-hierarchical problem. The method described in this document computes an approximation for the shortest path of VLSI design component instances taking full advantage of the hierarchical structure of the design. For the resulting path it is guaranteed that it contains at least one of the VLSI design component instances that cause the short. For each individual cell a Shortest Path Search (SPS) can be applied. In comparison to prior flat searches, which required unfeasible amounts of storage and computation time on large nets, this solution requires asymptotically not more storage and computation time than other forms of hierarchical VLSI checking tasks.
