Abstract: Fracturing methods include introducing a relatively high concentration of a surfactant in an initial portion of one or more fluids used in a fracturing treatment and then cutting or ramping back to a relatively low concentration of the surfactant in the remaining fluid used in the treatment. By using such a method, the volume of surfactant to provide superior treatment can be reduced significantly from the normal recommendations, leading to a high cost savings while still obtaining the desired effect upon cleanup.

Abstract: An anode for use in a high voltage electrolytic capacitor is provided. The anode contains a sintered porous pellet and a leadwire extending therefrom in a longitudinal direction. The pellet is multi-layered to the extent that it contains at least a first layer positioned adjacent to a second layer, both of which extend along the length of the anode. The anode leadwire is embedded within the first layer. For this reason, the first layer has a thickness greater than that of the leadwire. Nevertheless, the use of a separate and distinct second layer adjacent to the first layer can allow each of the layers to be independently pressed using a multi-sided compaction device so that the properties of the anode are not significantly impacted by the presence of the relatively large anode leadwire.

Abstract: Introduced here are techniques for generating color mixing models that enable a tunable lamp to mix the right amount of light from various color channels in order to properly produce colors. More specifically, a lamp controller can be configured to drive multiple light-emitting diode (LED) arrays based on corresponding color mixing models. One or more color mixing models can be provisioned into the memory of an LED array prior to usage. Storing the color mixing model in the LED array enables the lamp controller to update the color mixing model based on which LED array it is serving (i.e., the lamp controller and the LED array need not be a permanently matched set). Additionally or alternatively, the lamp controller may be configured to communicate with a network-accessible computer server system to access a historical color mixing database that includes set(s) of previously-recorded spectral properties and corresponding color mixing models.

Abstract: Various example concern techniques for opto-mechanically manipulating LED-based lighting systems. More specifically, various embodiments concern creating patterns of colored LEDs by determining the preferred color-specific density distribution and sequence(s) of LEDs. When creating the patterns, multiple considerations can be taken into account, including the power to be shared amongst the color channels when certain color models are generated by the linear array of LEDs, allocating an appropriate number of LEDs to each color channel to support the desired color spectrum, the sequencing of those LEDs along a string (e.g., as part of a linear array), etc. The appropriate number of LEDs for each color channel may be determined by first establishing the color model of the linear array within which the LEDs are interleaved.
