摘要： An ultrasonic welding system. The system includes an ultrasonic transducer assembly having a horn and a first transducer and a second transducer arranged to impart ultrasonic energy into the horn. The horn has a first part-interfacing surface and a second part-interfacing surface opposite the first part-interfacing surface. An actuator assembly is operatively coupled to the ultrasonic transducer assembly and configured to cause rotation of the horn. A controller is configured to: cause the actuator assembly to rotate the horn so that the first part-interfacing surface applies the ultrasonic energy to a first part along an entire length of the first part-interface surface while a first ultrasonic energy is applied through the horn via the first transducer to cause the first part-interfacing surface to vibrate back and forth along its entire length as the first ultrasonic energy is applied by the first transducer to the horn.

摘要： Ultrasonic transducer coupling adapters, ultrasonic transducer assemblies with an adapter, and methods for making and for using ultrasonic transducer adapter components are disclosed. An ultrasonic transducer assembly is disclosed for generating and transmitting ultrasonic energy to a work piece (e.g., non-resonant structures). The assembly includes piezoelectric actuators that generate ultrasonic vibrations in response to high-frequency electrical signals. A feedback system monitors and regulates voltages applied to the piezoelectric actuators. The assembly also includes an adapter that is connected to the piezoelectric actuators (e.g., via a front mass) and is configured to distribute the ultrasonic vibrations from the actuators to the work piece. The adapter reduces or substantially eliminates transmission back to the piezoelectric actuators of erratic strain generated by the work piece in response to these ultrasonic vibrations. The adapter helps to ensure that the ultrasonic transducer assembly vibrates with a simple axial motion when the work piece vibrates erratically.

摘要： A face covering includes layers of nonwoven material and at least one elastic element. The layers of nonwoven material cooperatively define a first opening, a second opening, and a filtration area of the face covering. The filtration area is arranged to allow airflow through the face covering and remove particulates from the airflow. The first opening and the second opening are sized to receive a head of a wearer. The at least one elastic element is secured to the layers of nonwoven material. The face covering is sized such that, when the face covering is positioned on the head of the wearer, the at least one elastic element provides a seal against the wearer and the layers of nonwoven material provide a loose fit on the wearer.

摘要： Identifying object characteristic based on a contrast ratio of an amount of light reflected or absorbed by the object. Part of the object is illuminated, where the object is a material that absorbs or reflects light emitted by the light source. An amount of light absorbed/reflected by the object is measured. A contrast ratio of the absorbed/reflected light is determined by comparing an amount of light absorbed/reflected by the object to a default absorption or reflection value to obtain a difference between the amount of light absorbed/reflected by the object and the default absorption/reflection value. A characteristic of the object is determined based on the contrast ratio. The wavelength of the light from the light source can be substantially the same as the wavelength of the energy used to form the object by a welding process that uses energy to join at least two parts together to form the object.

摘要： Device and method for laser welding around a circumference of a workpiece. A fixed, non-movable unitary optical reflector has a pair of optical reflecting surface portions on a first side surface and a second side surface, respectively, arranged at an obtuse angle relative to each other. A workpiece is fixed in an assembly having the reflector. During setup, the vertical distance is adjusted between the reflector and workpiece along an axis that is transverse to a longitudinal axis thereof without any adjustment of the reflecting surfaces. The first and second side surfaces define a curve that is transverse to the longitudinal axis. Once setup has been completed, a laser beam is directed so that it moves along the optical reflector to thereby produce a 360 degree circumferential weld around the workpiece. Another assembly is provided to change the laser beam direction multiple times to irradiate a circumference of a fixed workpiece from a fixed laser source.
