Abstract: An apparatus for powder spheroidisation by microwave-induced plasma comprises a microwave generator, a microwave cavity, a waveguide connecting the microwave generator to the microwave cavity, a plasma tube partially located in the microwave cavity, a powder supply connected to the plasma tube to feed a powder precursor flow thereinto, a gas supply connected to the plasma tube to feed a process gas flow thereinto, in order to form a plasma torch in the plasma tube by coupling the process gas flow with the microwave radiation, and a compressed air supply. The microwave cavity comprises at least one opening for the compressed air so that the latter can cool the plasma tube from outside, and the gas supply is connected to the powder supply to let the process gas carry the powder precursor into the plasma tube, and so into the plasma torch in order to make spheroids from the powder precursor by in-flight melting.

Abstract: Virtualization can be used to isolate drivers in monolithic operating systems. For example, a monolithic kernel can determine that a first driver has a first level of criticality to the monolithic kernel that is higher than a second level of criticality for a second driver. In response to determining that the first level is higher than the second level, the monolithic kernel can execute a first driver workload for the first driver. The monolithic kernel can also execute a virtual machine including a guest kernel. The guest kernel can execute a second driver workload for the second driver such that the second driver is isolated to the virtual machine. A communication channel can be generated between the guest kernel and the monolithic kernel such that the monolithic kernel can access the second driver workload via the communication channel.

The orthodontic bracket includes a channel formed between the bracket body and the ligating member, and a resilient biasing member extending into the channel, the biasing member interacting with the ligating member to retain the ligating member in either the open or closed position.

Abstract: A modular datacenter facility and a method thereof is provided in accordance with some embodiments. The module datacenter facility can be constructed with an initial set of building modules of different types of functionality. A first building module can be a data-floor building module. A first set of sidewall-connected heating, ventilation, and air conditioning (“HVAC”) units can connect to a sidewall of the modular datacenter facility and use electrical power provided by a first electrical power distribution building module to supply conditioned air into an air-supply plenum of the sidewall to cool computing systems housed in the data-floor building module. The first set of the sidewall-connected HVAC units allow for fewer penetrations in a roof of the data-floor building module, thereby minimizing an amount of leaks potentially occurring in the roof of the ceiling, and thereby minimizing risk of any damage to the computing systems.

The device further includes an arm with an elongate body having an attachment portion disposed along one end thereof and a bonding portion disposed along an opposite end thereof. The attachment portion includes a notch formed along an end face thereof and a seat in communication with the notch. The arm is removably mountable to the stem via the notch and the seat, the arm being rotatable about a rotational axis relative to the stem to a locked position where the arm is bonded in place to another tooth via the bonding portion for treatment.

Abstract: The present description relates to a 2D visual code based on the superposition of pure flat waves framed in black, designed to be read at long distances, with different types of degradation (noise, blurring or movement) and in adverse lighting conditions. To this end, the information carrying elements are waves that are distributed over the whole image. The combination of waves with different directions, frequencies, amplitudes and phases permits generating a high number of configurations that may be decoded in a robust and efficient manner.

The orthodontic bracket includes a bracket body mountable to a tooth and an adjustable hook extending from the bracket body, the adjustable hook comprising a stem base structure a bend region extending from the stem base structure, a neck region extending from the bend region, and a head extending from the neck region. In some embodiments, the adjustable hook has a length, L1, measured from a bottom portion of the stem base structure to the head, and a length, L2, measured from a bottom portion of the neck region of the hook stem to a free end of the head, wherein L2 is greater than or equal to 60% of L1.

Abstract: An instrument for facilitating opening of a ligating member for an orthodontic bracket. The instrument includes one tip designed to engage an opening feature on a labial side of a ligating door of the orthodontic bracket, and another tip designed to sit underneath a tie wing formed on a body of the orthodontic bracket. When the instrument is in position against the orthodontic bracket, squeezing together the handles results in the tips applying a reciprocal force on the ligating door and the bracket body to open the ligating door along the occlusal direction.

Abstract: An orthodontic bracket includes a bracket body with a recess on a top surface of the bracket body and an archwire slot adapted to receive an orthodontic wire. The orthodontic bracket also includes a ligating member with a projection on its bottom surface. The ligating member is movably connected to the bracket body for retaining the orthodontic wire in the archwire slot when the ligating member is moved from an open position to a closed position. The orthodontic bracket also includes a discrete spring positioned in the recess on the bracket body such that a force is required to move the ligating member from the open position to the closed position.

Abstract: The disclosure relates to an orthodontic system and treatment method, including an arrangement of orthodontic brackets against the patient's teeth such that the depth of the respective archwire slots of the brackets generally increases from the anterior teeth moving toward the posterior teeth. The gradual increase of the archwire slot in the bracket arrangement provides for finer control over the movement of the anterior teeth, while providing sufficient control and freedom of movement for the posterior teeth.
