摘要:
A wind instrument such as a harmonica has a mouthpiece with one or more air channels, an electric power source, and a means for generating an electrical output signal from strain gages exposed to airflow in the channels. First and second strain gages having variable flow-induced resistance are bonded to a flexible substrate and suspended within an air channel, which includes a divider shelf for directing a first airflow to the first strain gage and a second airflow to the second strain gage. Complimentary strain gages are mounted to an opposite side of the substrate for inverse flexure to enable temperature correction for the first and second strain gages. When a user forces air through a channel in a direction biased to one side of the divider shelf a difference signal is generated by the first and second strain gages and detected by comparing their outputs. The difference signal can be used to adjust a variable control signal in applications such as volume control, dimming lights, or bending notes generated by the harmonica.

A real time vehicle communications system comprises an interface unit configured to communicate with an onboard vehicle performance system and an onboard vehicle positioning system; a processor unit connected to the interface unit; a memory unit connected to the processor unit; a communications unit connected to the processor unit, the communications unit being configured for wireless communication. The processor unit is configured to store data from the vehicle positioning system and the vehicle performance system in the memory unit, and transmit at least some information from the memory unit, via the communications unit, to one or more peer vehicles outside the vehicle under the direction of a user; and one or more base stations outside the vehicle.

Techniques are provided for assigning extension numbers to Internet Protocol (IP) telephony devices. The techniques include receiving a message from the IP telephony device requesting that an extension be assigned. A port identifier of a port in which the IP telephony device is coupled is determined. Extension numbers are fixed for specific ports. Thus, an extension number for the port identifier of the port is determined. The extension number is then assigned to the IP telephony device. For example, a MAC address for the IP phone is assigned to the extension number.

My invention is called a “Personality Exchange Tablet” (PET) and represents a new product not seen before. The current similar products are baseball cards, coins, autographs, and memorabilia. A PET is designed to be a tradeable collectable or memorial for all people not just sports personalities. The key feature that this patent is to protect is that Personality Exchange Tablets contain a DNA (hair or other) sample of the given personality.Moreover, a Personality Exchange Tablet is a credit card size tablet minted in metal with the picture, signature, and basic information of a given personality. Along with these common features a PET has a hole in the minted metal tablet where a DNA vial of the given personality is inserted to create one collectable unit.
