摘要： An apparatus includes a control circuit to connect to an audio device of a safety system. The safety system is to detect a hazardous condition. The audio device is to alert a user of the hazardous condition. The safety system is to include a sensor to sense the hazardous condition. The apparatus includes an interface to connect the control circuit to the audio device. The control circuit is to determine whether to clean a housing of the sensor and, based on a determination to clean the housing of sensor, cause the audio device to vibrate or issue sound waves at an inaudible frequency.

摘要： Approaches, techniques, and mechanisms are disclosed for sensor cleaning systems. A region of a sensor window is identified to be blocked by an obscurant. The location of the region is determined using the sensor associated with the sensor window. An acousto-vibratory cleaning system receives the location of the region and produces a fluid droplet to be dispensed at a specified point on a two-dimensional plane of the surface of the sensor window. Sonic actuators are activated to capture the fluid droplet in acoustic levitation. Acoustic forces guide the fluid droplet to the region being obscured. Once the fluid droplet is in cleaning position, vibration of the sensor window is activated to incrementally clear the obscurant by vibrating the droplet along the obscurant. The acousto-vibratory cleaning system generates additional acoustic forces to guide the contaminated fluid droplet to a closest drainage canal.

摘要： A self-cleaning sensor guard is provided. The guard may comprise an acoustic duster housing, a dust guard, a proximity sensor, a phase-enabled controller, and an ultrasonic cleaning source. The dust guard may be positioned to impede passage of ambient particulates into the acoustic duster housing. The proximity sensor may be positioned to generate a dust detection signal that is indicative of the presence of particulates on the dust guard. The ultrasonic cleaning source may be oriented to direct multi-phase and multi-frequency ultrasonic cleaning waves towards the dust guard. The phase-enabled controller may be programmed to drive the ultrasonic cleaning source, at least partially in response to the dust detection signal, by superimposing a first acoustic signal and a second acoustic signal.

摘要： A system for removing a coating from an underlying layer can include a wave-based weakening system configured to weaken the coating by decreasing a coupling force between the coating and the substrate, a coating removal mechanism configured to remove the weakened coating from the underlying layer, and a sensor configured to determine a property associated with the coating. A method for removing a coating from an underlying layer can include generating a weakened coating and removing the weakened coating.

摘要： Self-cleaning device and method using electrical oscillation and mechanical oscillation are disclosed. The self-cleaning device comprises at least one first electrode disposed on a solid material layer, a first dielectric layer disposed on the first electrode, a hydrophobic layer disposed on the first dielectric layer and at least one mechanical oscillation unit. Here, electrical oscillation for oscillating a droplet in a horizontal direction is generated by applying a first electric signal to the first electrode, thereby merging the droplets formed on the hydrophobic layer, and the mechanical oscillation unit moves the merged droplets in a specific direction or atomizes the merged droplets to remove the merged droplets by generating mechanical oscillation for oscillating the droplet in a vertical direction.

摘要： The present disclosure is directed to a method for cleaning gas turbine engine components using an acoustic emitter. More specifically, in one embodiment, the method includes positioning the acoustic emitter at a cleaning location of a component of the gas turbine engine. For example, the cleaning location is typically characterized by having a build-up of foulants on a surface thereof. Thus, the method includes emitting, via the acoustic emitter, acoustic waves at a predetermined frequency towards the cleaning location of the component so as to disperse the foulants.

摘要： A system and method are disclosed for using a sonic frequency to induce a vibration useful for clearing dust accumulation from microelectronics, such as a laptop computer. A speaker driver may be mounted onto a support structure for a heat exchanger (220). At an advantageous time, such as boot up, a sonic frequency may be driven onto the speaker (250), thus inducing vibration in the heat exchanger (220) and helping to clear dust accumulation. In some cases, a resonant frequency may be used to optimize the amount of vibration per unit power delivery.

摘要： Disclosed herein is a high-efficiency acoustic wave generator using a pulsed thermal radiation beam. The generator is configured such that when a pulse beam formed by a light interrupter is directly radiated onto a porous material having a woven net or steel scrubber shape, thin wires of the porous material repeatedly rapidly thermally-expand and contract, whereby air in the space between the wires is momentarily heated and cooled, and the expansion and contraction of air is directly transmitted to an air column formed just adjacent to the porous material. By virtue of the above structure, the efficiency of the generator is markedly improved compared to the conventional technique, and the productivity is also greatly enhanced.
