Abstract: Embodiments of the disclosure are drawn to apparatuses and methods for bad row mode. The memory may prevent proper access operations (e.g., read operations) from being performed on a selected bad row of the memory as part of a bad row mode. For example, the memory may store a bad row address and when an access address matches the bad row address, may suppress one or more signals, change data read from the address, or combinations thereof. The bad row mode may be used to provide a positive control for post package repair (PPR) operations on the memory. A controller may enter the memory into bad row mode and then test the memory to determine if the selected bad row can be located and repaired via PPR.

Abstract: A drum smoking assembly is configured to utilize uniform, cyclonic circulation flow of air, heat and smoke for smoking and cooking food. The drum smoking assembly has a drum smoker that is approximately cylindrical and further comprises interior and exterior surfaces. Two side openings extend through the interior and exterior surfaces which are joined to air intakes tangentially connected to the exterior surface. A basket is arranged within the drum smoker above the first side opening and the second side opening. A twelve vane straightening perforate plate is arranged within the drum smoker above the basket. A lid is rotationally connected to the drum smoker and further comprising a chimney cap. A heat source in the basket pulls air through the first air intake and the second air intake that is then pushed through the twelve vane straightening perforate plate toward the chimney cap, creating a cyclonic air flow.

Abstract: Methods for accessing a disc space of a patient as a part of an interbody fusion, as well as the tools employed therewith. An exemplary method may include inserting a leading end of a tool into the patient's back at a location on the posterior surface that is laterally offset from a patient's spinous process and disc. The tool's initial entry into the patient may be from a posterior approach. As the tool is advanced along its designated path, it begins to deviate from the posterior approach towards a lateral approach. When the leading end reaches the disc, it may access the disc from a lateral or substantially lateral location. The tool may be used to access the disc location, to remove disc material, to deliver a cutting tool for removing the disc material, and other steps associated with the spinal interbody fusion procedure.

Abstract: A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing is operationally coupled to the shift actuator and a linear clutch actuator. The linear clutch actuator is a self-adjusting actuator, and the transmission includes a self-adjusting clutch.

Abstract: In accordance with at least one aspect of this disclosure, there is provided a heat exchange system. The heat exchange system includes a first heat exchanger and a second heat exchanger. The first heat exchanger includes an engine fluid conduit fluidly connecting an engine fluid inlet to an engine fluid outlet. A first internal buffer fluid conduit fluidly connects a first buffer fluid inlet to a first buffer fluid outlet where the engine fluid conduit is in fluid isolation from the first internal buffer fluid conduit but is in thermal communication with the first internal buffer fluid conduit for heat exchange between the engine fluid and the buffer fluid.

Abstract: An audio speaker cover with a central region and a peripheral region. The central region has a surface that faces an observer and a speaker cover body below the surface. The audio speaker cover body defines a plurality of apertures with lands between the apertures. The apertures have cylindrical walls that meet the surface orthogonally. Precisely engineered apertures permit minimal sound transmission loss and allow a high aperture density without sacrificing the ability of intervening lands in the audio speaker cover to protect an underlying speaker.
