摘要:
The invention can be worn by the swimmer and comprises a sensor module, preferably with a digital compass and accelerometer, preferably worn under a swim cap or attached to goggles, and a human interaction device, preferably integrated into or worn as wrist watch, for displaying laps. The sensor module and the human interaction device are in communication with each other, preferably via wireless communication. A microprocessor with software is included in either the sensor module, watch or both. The microprocessor/software interprets data from a digital compass and digital accelerometer within the sensor to determine when the swimmer has changed directions and thereby count the number of laps. The watch can then display the number of laps.

摘要:
The invention provides devices for the disruption of one or more layers of skin and methods of their use to administer therapeutic agents, e.g., antigens or drugs. The devices are designed to disrupt a defined area of skin. The defined area can approximate the area that a patch or other suitable vehicle for therapeutic agent, e.g., drug or vaccine, delivery is designed to contact. Exemplary devices employ a mask to define the area to be disrupted. Other devices disrupt a defined area by rotating in place. For devices that employ a mask that is secured to the skin, the invention provides methods of disrupting the stratum corneum by first securing the mask to the skin and then disrupting the skin. For rotating devices, the disrupting member is simply placed against the skin and actuated to effect disruption.
