Abstract: Described herein are examples of torch tracking systems that monitor travel directions, speeds, and/or distances of welding torches using retractable cords. In some examples, the torch tracking systems use a sensor to measure a speed at which a reel extends and/or retracts a cord, and/or measure a length of the cord that is extended and/or retracted. The reel or cord can be attached to some portion of the welding torch, such that movement of the torch away from the reel causes the reel to extend more cord, and movement towards the reel allows a spring loaded spool of the reel to automatically retract the cord. While reel based torch tracking systems may provide coarser tracking than the more complex and/or expensive torch tracking solutions, their simplicity and low cost may make them an attractive alternative.

Abstract: Various systems and methods for aggregating data from disparate sources to determine an optimal package of data items are disclosed. For example, the system described herein can obtain data items from various sources, aggregate and/or organize the data items into an optimal package based on various criteria, and present, via an interactive user interface, the optimal package. Furthermore, the interactive user interface may enable a user to adjust the criteria used to aggregate and/or organize the data items. The system may interactively re-aggregate and re-organize the data items using the adjusted criteria as the user interacts with the package via the user interface. The system and user interface may thus enable the user to optimize the packages of data items based on multiple factors quickly and efficiently.

Abstract: Disclosed herein are methods of fabricating a packaged radio-frequency (RF) device. The disclosed methods use an encapsulant on solder balls in combination with a dam or a trench to control the distribution of an under-fill material between one or more components and a packaging substrate. The encapsulant can be used in the ball attach process. The fluxing agent leaves behind a material that encapsulates the base of each solder ball. The encapsulant reduces the tendency of the under-fill material to wick around the solder balls by capillary action which can prevent or limit the capillary under-fill material from flowing onto or contacting other components. The dam or trench aids in retaining the under-fill material within a keep out zone to prevent or limit the under-fill material from contacting other components.
