Abstract: An oxygen delivery apparatus includes a pneumatic conserving device which uses a portion of gas exiting its main valve to interrupt delivery of the gas. Gas is dispensed upon inhalation and is interrupted by means of suitable pneumatic connections between the device's delivery system and its sensing system. In some versions, the apparatus comprises an oxygen concentrator and the conserving device operates to deliver oxygen generated by the concentrator upon inhalation, and interrupts such delivery substantially independently of exhalation.

Abstract: A wireless terminal with virtual memory for use in a wireless communications network and a method of using such a wireless terminal is provided. The wireless terminal comprises a transceiver for receiving and transmitting information over an active wireless link with the communications network, virtual memory to store information received over the wireless link with the communications network and display means to view the information stored in the virtual memory without requiring the active wireless link with the communications network. The method of using the wireless terminal with virtual memory comprises the steps of downloading data from a server over an active wireless link to the virtual memory of the wireless terminal and accessing the data stored in the virtual memory at the wireless terminal without requiring the active wireless link.

Abstract: A portable, cryogenic gas delivery apparatus includes a chamber which contains cryogenic material, such as oxygen, in both liquid and gas phases. A probe is mounted to move relative to the chamber in response to variations in pressure in the gas phase within the chamber. The probe has one part positioned within the chamber so that it is exposed to the pressure and temperature of the gas within the chamber and a second part located outside the chamber. The probe thus introduces heat from the ambient into the chamber. The probe preferably moves relative to the chamber in response to variations in pressure, moving away from the chamber to reduce the amount of thermal energy introduced into the chamber and toward the chamber to increase the amount of thermal energy introduced into the chamber. The apparatus includes a conserver which receives gas evaporating from the chamber and delivers it in efficient pulses to the end user in response to the user's inhalation.
