In other examples, a solid braze material including a filler material and a metal or alloy may be delivered to the joint region and locally heated to cause a constituent of the filler material and a constituent of the metal or alloy to react. When reacted, the constituents may form a solid material, which may join the first and second parts.

Abstract: This invention provides a convenient method of forming and applying a thermoplastic material for roadway markings, comprising: obtaining individual components of a thermoplastic composite material suitable for roadway markings; mixing and heating the individual components to produce a fully compounded form of the thermoplastic composite material; solidifying and prilling the fully compounded form of the thermoplastic composite material to produce a plurality of thermoplastic prills; on a marking vehicle or mobile apparatus, introducing the thermoplastic prills to an on-board melter to produce a liquid phase of the thermoplastic prills; and applying the liquid phase of the thermoplastic prills to a roadway, thereby marking the roadway. Compositions and systems are also described. Surprisingly, prills melt in approximately half the time as the powder/granular form. Also, the melter can be operated at lower temperature, leading to less discoloration of material.

Abstract: Examples described herein can be used to reduce a number of re-read operations and potentially avoid data recovery operations, which can be time consuming. A determination can be made of a read voltage to apply during an operation to cause a read of data stored in a region of a memory device. The region of the memory device can be read using the read voltage. If the region is not successfully read, then an error level indication can be measured and a second read voltage can be determined for a re-read operation. If the re-read operation is not successful, then a second error level indication can be measured for the re-read operation. A third read voltage can be selected based on the change from the error level indication to the second error level indication.
