摘要:
A pull-based method for disseminating marketing information to customers based on specific customer requests through a web based portal connected to a sever with a database of product information. The customer can receive the information via a variety of mediums from a distribution hub connected to the server. Information on consumer choices is stored on the server, which can be collated, ranked, and prioritized for use in tracking consumer requests for information.

A circuit (FIGS. 2A-2D) and method of providing an auto-on and/or auto-off capability for an audio device, of a type having an audio plug (14) which mates with the output jack of an audio source. The portable transmitter (10) modulates audio signals from the audio source onto a carrier and transmits them to a receiver. The auto-on and auto-off capability is provided to prolong battery life and degradation of the transmitter circuit and comprises pinching off a FET (Q2) when the circuit is in an “off” state. This occurs when a pre-determined threshold in a capacitor is reached by not discharging that capacitor. The capacitor (C29) is discharged by dropping a comparator input below a pre-determined threshold limit when presented with an audio peak and wherein the drop in value causes the comparator output to go low, causing the capacitor to discharge and causing the FET (Q2) to supply power to the regulator.

摘要:
A circuit and method for providing an auto-off capability for a wireless transmitter, of a type having an audio plug which mates with the output jack of an audio source. The portable transmitter modulates signals from a baseband signal source onto a carrier and transmits the RF carrier to a receiver. The auto-off capability is provided to prolong battery life and eliminate the transmission of unmodulated RF carriers. The auto-off capability comprises turning power off to the transmitter circuit when baseband input signal is absent for more than a predetermined amount of time, and immediately turning on the transmitter circuit when baseband signal is present.
