Abstract: A remote radio receiver includes audio circuitry, a user selection interface, user control circuitry and input/output interface. The audio circuitry is for receiving a digital audio stream and playing extracted audio signals over a speaker. The user control circuitry generates control signals as a result of a user interacting with the user selection interface. The input/output interface provides connection to a remote computer. The input/output interface forwards the digital audio stream from the remote computer to the audio circuitry. The input/output interface forwards the control signals from the user control circuitry to the remote computer.

Abstract: Disclosed is a method of determining imminent ink exhaustion in a thermal inkjet print cartridge based on the discovery that ink drop volume falls at a faster rate at high frequency firing rates than at low frequency firing rates as ink supply diminishes. The method includes warming the print cartridge printhead and ink to a predetermined temperature; then operating the print cartridge printhead at a first firing frequency to eject a volume of ink, said operating step including heating the ink and printhead, carrying away heat in the ejected volume of ink, and conveying a volume of cooler ink to the printhead to replace the ejected volume; and monitoring a first temperature change from the predetermined temperature.
