Abstract: A device for drying hair includes a housing having an air inlet and an air outlet spaced from the air inlet to define an airflow path through the housing. The device also includes a fan disposed within the housing along the airflow path, a hairstyling implement disposed at the air outlet, and an ultrasonic transducer configured to generate ultrasonic vibrations. The transducer is coupled to the hairstyling implement to transmit the ultrasonic vibrations to the hair.

Abstract: A device for styling hair includes a handle and a barrel extending from the handle. The barrel has a styling surface spaced from the handle, and the styling surface is configured for winding the hair around the barrel. The device further includes a heating element in thermal communication with the barrel to transfer heat to the hair via the styling surface of the barrel, and an ultrasonic transducer configured to generate ultrasonic vibrations. The ultrasonic transducer is disposed within the barrel to transmit the ultrasonic vibrations to the hair via the styling surface of the barrel.

Abstract: A device for styling hair includes a wand defining a handle grip surface and a first styling surface spaced from the handle grip surface and a plate defining a second styling surface, the plate being pivotally coupled to the wand to clamp the hair between the first styling surface and the second styling surface. The device further includes a heating element in thermal communication with the first styling surface or the second styling surface to transfer heat to the hair via the first styling surface or the second styling surface, respectively, and an ultrasonic transducer configured to generate ultrasonic vibrations. The ultrasonic transducer includes a horn in contact with the wand or the plate to transmit the ultrasonic vibrations to the hair via the first styling surface or the second styling surface, respectively.

Abstract: A method and apparatus for testing a pulse oximeter which is based on the concept of an electrical interface between the testing instrument and the oximeter rather than an optical interface. The pulse oximeter signal processor is tested separately from the probe, and still further, the optical elements, that is, the LEDs and the photodiode, of the probe are tested separately from the probe cable. With the probe disconnected from the oximeter, a modulated electrical test signal representative of SpO.sub.2 values and other parameters is generated in response to an electrical signal from the oximeter, and the test signal is applied to the oximeter signal processor, whereby the display of the oximeter shows a value of SpO.sub.2 which is compared with the SpO.sub.2 value represented by the test signal. Independently, the probe including the probe cable, the LEDs and the photodiode are respectively and separately subjected to continuity and optical sensitivity tests.

Abstract: An apparatus for evaluating the performance characteristics of an oscillometric blood pressure monitor is presented. In accordance with the present invention, a novel closed-loop system is used to synthesize physiologically-correct pneumatic pulse waveforms and oscillometric envelopes in order to allow dynamic performance evaluation of any oscillometric monitor, regardless of manufacturer.
