Abstract: A hair styling device for twirling locks of hair together including a main body, and at least two hair grabbers for respectively grabbing separate locks of hair. Each of the hair grabbers is connected to respective hair twisters, and each of the hair twisters rotates respective locks of hair to form twists of hair. The device further comprises a hair twist rotator body connected to each of the hair grabbers. The hair twist rotator body is connected to and rotatable relative to the main body. Rotation of the hair twist rotator body cables the twists of hair to form a cord of hair. The hair grabbers are substantially stationary relative to the hair twist rotator when the hair twist rotator rotates relative to the main body.

Abstract: By providing pressure-responsive switch-actuation means constructed for being substantially unaffected by temperature changes, a pressure sensor is attained which is capable of monitoring pressure levels with precision, regardless of the ambient temperature to which the system is subjected. By employing temperature insensitive material to effectively compensate for temperature changes incurred by the remaining sensor components, the actuation control assembly of the sensor is capable of achieving precision monitoring of desired pressure levels regardless of changes in the ambient temperature to which the monitor assembly is exposed. In one preferred embodiment, the pressure sensor of the present invention incorporates a uniquely constructed, machined bellows which further enhances and provides precision pressure sensing capabilities.
