Abstract: A driver circuit includes a drive circuit, a monitoring circuit, and a control circuit. The drive circuit includes a first current source and drives a switching element when the first current source is connected to a control terminal of the switching element. The monitoring circuit monitors a period of time from a start to an end of a change in a voltage drop across the switching element. The control circuit controls a current value of the first current source based on the monitored period of time such that a slew rate of the voltage drop across the switching element approaches a target value.

Abstract: A method of removing condensate banking in a subsurface formation using a treatment fluid includes injecting a treatment fluid including nanoparticles and a thermochemical component, the thermochemical component including sodium nitrite and ammonium chloride, into a wellbore having condensate banking, thereby exposing the treatment fluid to subsurface formation conditions. The method further includes allowing a temperature of the wellbore to activate the thermochemical component, causing an exothermic reaction generating nitrogen gas, pressure, and heat. The method further includes allowing the treatment fluid and generated nitrogen gas to mix with the condensate banking, thereby forming a homogenous multi-phase foam and lowering hydrostatic pressure in the wellbore. The method further includes allowing the homogenous multi-phase foam to flow back to the surface due to the pressure generated by the exothermic reaction and lowered hydrostatic pressure in the wellbore, thereby removing the condensate banking.

Abstract: Techniques for implementing an augmented audio conditioning (AAC) system are described herein. In some examples, the AAC system can store conditioning data comprising crowd noise experiences associated with context-relevant environments and/or actions associated with an activity. The AAC system can detect an action of a user who is training in a conditioning environment and determine that the action is associated with the activity. In some examples, the AAC system can also determine an association between the action of the user and audio data representing a crowd noise experience of a context-relevant environment during an event. Furthermore, the AAC system can, in response to detecting the action of the user, output the audio-conditioning data into the conditioning environment to simulate the crowd noise experience of the context-relevant environment during the event.

Abstract: Methods, systems, and devices for write buffer extensions for storage interface controllers are described. Apparatuses and methods are presented in which a buffer may be used to temporarily store data from an application if the memory device is in an INACTIVE power mode. This may allow the memory device to remain asleep. The buffer may be positioned on the host device so that the power mode of the memory device may not affect it. That way, data may be stored in the buffer without waking up the memory device. If the memory device is in an ACTIVE power mode, the data that has been temporarily stored in the buffer may be sent to the memory device for storage. During read operations, if the requested data is stored in the buffer, it may be used instead of data in the memory device.
