  • Patent number: 6692626
    Abstract: Methods for forming adsorbent laminate structures particularly for use in pressure swing adsorption processes and devices are disclosed. One disclosed embodiment comprises providing a metal or alloy support and depositing adsorbent material onto the support by electrophoretic deposition. Adsorbent material also may be deposited on plural strips, which are then assembled into a laminate structure along the support. Adsorbers also are described comprising first and second wire mesh sheets having adsorbent material deposited on a first major planar surface thereof. The first and second sheets are placed adjacent one another and spaced sufficiently to define a flow channel. Another disclosed embodiment comprises plural wire mesh sheets having adsorbent material deposited on both first and second major opposed planar surfaces thereof, the sheets being spaced from each other to define a gas flow channel. The adsorber may include ventilation gaps to provide ventilation between flow channels.

  • Patent number: 6590946
    Abstract: An input sequence of unwarped signal samples is stored in an input buffer (101). A pitch and voicing analysis unit (103), which analyzes voicing classification data from the input buffer (101), provides a voicing classification variable indicating whether the voicing classification data is voiced or unvoiced and a preliminary estimate of the signal period in the interval spanned by the voicing classification data to a pitch pulse detection unit (104). The pitch pulse detection unit (104), also using analysis frame data from the input buffer (101), provides a set of locations of unwarped pitch pulses contained in the interval spanned by the analysis frame data to a mapping optimization unit (105). The mapping optimization unit (105) provides a set of parameters describing a mapping from an unwarped time-scale to a warped time-scale, to a warped sampling instant calculation unit (106).

  • Publication number: 20030079057
    Abstract: A method of transferring a digital item session state between at least two devices (A, B) using digital items, the method including: providing a content digital item to one of said devices (B); the one of said devices (B) configuring said content digital item according to predetermined requirements; transferring one or more context digital items representing the content digital item's session state from the other device (A) to the one device (B) and the one device (B) configuring said content digital item on the basis of the context digital item. A method of configuring a digital content item on the basis of a stored digital context item is also disclosed.

  • Publication number: 20020177024
    Abstract: Herein disclosed is a metal air electrochemical cell, which generally includes an anode metal fuel material that may be infused into a container. The container may comprise a metering device, such as a toothpaste-like container, a syringe-like container, a caulking tube type container, a disposable condiment-like container, etc. These metering devices facilitate dispensing of a quantity of the metal fuel paste into a suitable structure generally including a cathode, a separator, and current collectors.

  • Patent number: 6406523
    Abstract: Gas separation by pressure swing adsorption (PSA) is performed within an apparatus having a plurality of adsorbers cooperating with first and second valves in a rotary PSA module, with the PSA cycle characterized by multiple intermediate pressure levels between the higher and lower pressures of the PSA cycle. Gas flows enter or exit the PSA module at the intermediate pressure levels as well as the higher and lower pressure levels, under substantially steady conditions of flow and pressure. The PSA module comprises a rotor containing laminated sheet adsorbers and rotating within a stator, with ported valve faces between the rotor and stator to control the timing of the flows entering or exiting the adsorbers in the rotor.

  • Publication number: 20020022146
    Abstract: Methods for forming adsorbent laminate structures particularly for use in pressure swing adsorption processes and devices are disclosed. One disclosed embodiment comprises providing a metal or alloy support and depositing adsorbent material onto the support by electrophoretic deposition. Adsorbent material has been deposited on just one planar surface, and on both first and second planar surfaces, of the support. Adsorbent material also may be deposited on plural strips, which are then assembled into a laminate structure along the support. Adsorbers also are described comprising first and second wire mesh sheets having adsorbent material deposited on a first major planar surface thereof. The first and second sheets are placed adjacent one another and spaced sufficiently to define a flow channel.
