Abstract: The disclosure relates to an audio processing apparatus for localizing an audio source. The audio processing apparatus comprises a plurality of audio sensors, including a primary audio sensor and at least two secondary audio sensors, configured to detect an audio signal from a target audio source, wherein the primary audio sensor defines at least two pairs of audio sensors with the at least two secondary audio sensors; and processing circuitry configured to: determine for each pair of audio sensors a first set of likelihoods of spatial directions of the target audio source using a first localization scheme; determine a second set of likelihoods of spatial directions of the target audio source using a second localization scheme; and determine a third set of likelihoods of spatial directions of the target audio source on the basis of the first sets of likelihoods and the second set of likelihoods.

Abstract: An apparatus determines a spatial position of an audio source in multi moving audio sources scenarios. The apparatus receives audio signal versions as local sound waves. The apparatus determines first and second probabilities for a direction of arrival of the audio signal version based on the audio signal versions received within a first time interval; determines third and fourth probabilities for the direction of arrival of the audio signal version based on the audio signal versions received within a second time interval; determines a first probability difference between the first and third probabilities; determines a second probability difference between the second and fourth probabilities; combines the third probability and the first probability difference to obtain an updated third probability; combines the fourth probability with the second probability difference to obtain an updated fourth probability; and determines the spatial position based on the updated third and fourth probabilities.

Abstract: A method for particle beam-induced processing of a defect of a microlithographic photomask, including the steps of: a) providing an image of at least a portion of the photomask, b) determining a geometric shape of a defect in the image as a repair shape, with the repair shape comprising a number n of pixels, c) subdividing, in computer-implemented fashion, the repair shape into a number k of sub-repair shapes, with an i-th of the k sub-repair shapes having a number mi of pixels, which are a subset of the n pixels of the repair shape, d) providing an activating particle beam and a process gas at each of the mi pixels of a first of the sub-repair shapes for the purposes of processing the first of the sub-repair shapes, e) repeating step d) for the first of the sub-repair shapes over a number j of repetition cycles, and f) repeating steps d) and e) for each further sub-repair shape.

Abstract: A solenoid valve can include a valve body and an actuator. The actuator can include an actuator housing, a coil disposed in the actuator housing and a core tube extending from the valve body through and beyond the actuator housing when the actuator is properly installed on the valve body. A monitoring assembly can include a target on the core tube and a detector configured to detect the target when the actuator is properly installed on the valve body and/or core tube.

Abstract: A fan assembly includes a first fan, a second fan, and a controller. The controller is configured to determine that an air movement demand corresponds to operation of the first fan and the second fan at a resonance speed, instruct the first fan to operate at a first speed which is less than the resonance speed, and instruct the second fan to operate at a second speed which is greater than the resonance speed.

Abstract: A blower includes an impeller configured to be turned about a rotational axis of the impeller, and a housing. The housing includes a wrapper which curves in a circumferential direction about the rotational axis along a spiral contour. The housing also includes a side wall coupled to an edge of the wrapper such that an inner transition region between the side wall and the wrapper, which at least partially forms a flow path of the blower between an inlet and an outlet of the blower, is rounded and not pointed.

Abstract: A heating, ventilating, and air conditioning (HVAC) blower that includes a housing that defines an air inlet, an air outlet, and a passageway therebetween. An airflow may be directed from the air inlet to the air outlet through the passageway. The housing at the air outlet includes an outlet end portion with a plurality of flutes that extend from the passageway.

Abstract: A method for regenerating deactivated acidic ionic liquid is described. The method involves reducing a level of free hydrochloric acid in the deactivated acidic ionic liquid in a removal zone using at least one of heat, a stripping fluid, reduced pressure, and liquid-liquid extraction to form a deactivated acidic ionic liquid having a reduced level of free hydrochloric acid; and regenerating the deactivated acidic ionic liquid having the reduced level of free hydrochloric acid.

Abstract: A follower assembly includes a follower mounted on an axle with the axle being coupled to a carrier that is pivotable relative to the frame about a pivot axis. The follower assembly has a locked position in which the pivot axis and axle are positioned relative to each other in a locked over-center position. In the locked over-center position the driver is pinched between the follower assembly and the flywheel subjecting the driver to a pinch force when the driver is in the stall position. When the driver is in the stall position and the follower assembly is in the locked over-center position, pivotal movement of a stall release lever toward the release position forces the follower assembly out of the locked over-center position toward the reverse over-center position in which the relative positions of the pivot axis and axle are reversed and the pinch force is released.

Abstract: A flywheel-driven tool includes a ferromagnetic driver. The driver has a firing position in which the driver is drivingly engaged against the flywheel. The driver also has a home position radially further away from the flywheel than the firing position when the flywheel is spinning in preparation to firing the driver. A magnet is positioned adjacent the driver to exert a magnetic force on the driver to pull the driver into the home position.

Abstract: Compression return springs can be mounted on rails between the driver and an impact absorber. The springs include a plurality of wires twisted together to form a multi-stranded twisted wire member, which forms the coils of the spring. The springs can have an inner diameter that resists movement of the coils along the rails when the spring is at its free length, but has a mounted inner diameter that freely allows such movement. The coil-to-coil pitch of the spring can vary along its length. A motor initially rotates the flywheel without engaging the driver. The driver then contacts the rotating flywheel to propel the driver, which compresses the return springs against the impact absorbers as the driver travels from the returned position to the extended position.

Abstract: The present specification discloses systems and methods for patient monitoring using a multitude of display regions, at least two of which have the capability to simultaneously display real time patient waveforms and vital statistics as well as provide display for local and remote software applications. In one example, a primary display shows real time patient waveforms and vital statistics while a customizable secondary display shows trends, cumulative data, laboratory and radiology reports, protocols, and similar clinical information. Additionally, the secondary display can launch local and remote applications such as entertainment software, Internet and email programs, patient education software, and video conferencing applications. The dual display allows caregivers to simultaneously view real time patient vitals and aggregated data or therapy protocols, thereby increasing hospital personnel efficiency and improving treatment, while not compromising the display of critical alarms or other data.
