Abstract: A housing has a bud portion abutting an elongated stem portion. The bud portion is to fit within an ear. The bud portion has a primary sound outlet at its far end that is to be inserted into an outer ear canal, and abuts the stem portion at its near end. A speaker driver is inside the bud portion. Electronic circuitry inside the housing includes a wireless communications interface to receive audio content over-the-air and in response provides an audio signal to the speaker driver. A rechargeable battery as a power source for the electronic circuitry is located inside a cavity of the stem portion. Other embodiments are also described and claimed.

Abstract: A method for operating a laser system for a medical procedure, or a similar system, comprises detecting presence of a portable memory device like a smart card coupled to the laser system, and reading data on the portable memory device usable to identify an associated delivery device. An identifier is read from the associated delivery device after it is coupled to the laser. A process is executed to verify the configuration including matching the identifier read from delivery device with the delivery device associated with the portable memory device, verifying that the portable memory device includes a data structure adapted for storage of an event log, and enabling delivery of laser energy if said authenticating and said verifying are successful. A kit comprising a delivery device and a portable memory device supporting the process is provided to users of the laser system.

Abstract: This invention provides cutter/lighter combination devices wherein the cutter is equipped with a blade attached to a holder that moves on a track. The end of the blade holder distal from the blade edge protrudes from a notch in the side of the case. When the protruding portion of the blade carrier is pushed forward in the direction of the case, the blade moves forward across the aperture to cut any object which has been inserted into the aperture. The blade edge may be any shape, so long as the cutting edge is not present in the aperture in the absence of pressure on the blade carrier to force the blade edge to move the blade across the aperture.
