Additionally, the controlled sampling may be any one of the following: sampling in accordance with a preprogrammed regimen, sampling at a controlled rate, delayed sampling, pulsatile sampling, chronotherapeutic sampling, closed-loop sampling, responsive to a sensor's input, sampling on demand from a personal extracorporeal system, sampling regimen specified by a personal extracorporeal system, sampling on demand from a monitoring center, via a personal extracorporeal system, and sampling regimen specified by a monitoring center, via a personal extracorporeal system. Specimen collection in the oral cavity may be assisted or induced by a transport mechanism, such as any one of, or a combination of iontophoresis, electroosmosis, electrophoresis, electroporation, sonophoresis, and ablation. The oral devices require replacement at relatively long intervals of weeks or months. The oral devices and methods for controlled specimen sampling apply to humans and animals.

Communication operation is performed with enhanced transmission efficiency by obtaining enhanced communication capacity through optimal allocation of transmission powers to individual MIMO channels obtainable by spatial multiplexing. A transmitter has a plurality of transmission antennas and a receiver has a plurality of reception antennas and perform spatial multiplex communication through transmission and reception with individual antenna weights being set. The transmitter varies the power allocation in units of a communication channel in correspondence to communication quality of the channel.

The present invention is a method of doing business over a network that: receives a request for transmitting digital information after a start time and before an end time, determines the time required to transmit the digital information based on the number of packets in the information and the network speed, schedules a transmit time for the digital information, and accepts the digital information for transmission only if the time required to transmit is less than or equal to the difference between the transmit time and the end time. Pricing of the transmission can be determined by the priority of transmission, whether the information is transmitted the first time or rescheduled, and whether the user receives an acknowledgment.
