International Classification:

G01N 27407

US Classification:

205775, 204425, 204426, 204427

Abstract:

A hydrogen sensor and process for measuring hydrogen gas concentrations includes a pump cell and a measuring cell. The pump cell includes a first conducting electrolyte layer having a top and a bottom surface, and an electrode disposed on the top and bottom surfaces, wherein the top electrode is in communication with an unknown concentration of hydrogen gas. The measuring cell includes a second conducting electrolyte layer having a top and a bottom surface, and an electrode disposed on the top and bottom surfaces, wherein the bottom electrode is in communication with a reference gas source. A diffusion-limiting barrier is disposed between the pump cell bottom electrode and the measuring cell top electrode, wherein hydrogen diffusion through the diffusion-limiting barrier is controlled by a Knudsen diffusion mechanism at hydrogen concentrations greater than about 40%.

US Classification:

438219, 438295, 438404, 438787, 438788

Abstract:

High density plasma chemical vapor deposition and etch back processes that can fill high aspect ratio (typically at least 5:1, for example 6:1), narrow width (typically sub 0. 13 micron, for example 0. 1 micron or less) gaps with significantly reduced incidence of voids or weak spots are provided. This deposition part of the process may involve the use of any suitable high density plasma chemical vapor deposition (HDP CVD) chemistry. The etch back part of the process involves an integrated multi-step (for example, two-step) procedure including an anisotropic dry etch followed by an isotropic dry etch. The all dry deposition and etch back process in a single tool increases throughput and reduces handling of wafers resulting in more efficient and higher quality gap fill operations.

International Classification:

H04B001/00

US Classification:

455567, 455566

Abstract:

Improved techniques for controlling notification characteristics for wireless communication devices are disclosed. One aspect of the improved techniques pertains to timer-based notification control for wireless communication devices. Another aspect of the improved techniques pertains to calendar-based notification control for wireless communication devices. Still another aspect of the invention pertains to graphical user interfaces that can be utilized to set or monitor notification characteristics for wireless communication devices. The improved techniques are particularly suitable for use with wireless communication devices having constrained keypads and wireless browsers that display documents (e. g. , such as markup language documents) or messages to users of the wireless communication devices.

US Classification:

709204, 455422, 455466, 455408, 455403, 455406

Abstract:

A method and apparatus for providing hypermedia content maintained remotely on a network to a wireless device without a browser are described. A Short Message Service (SMS) request for Internet-based content is received from the wireless device at a proxy server, via an SMS Center (SMSC). The SMS request is transmitted to the SMSC on a wireless network. The proxy server transcodes the SMS request from a character set of the SMSC to a character set of an application and extracts a keyword from the trancoded request. The proxy server maintains a mapping of keywords to URLs. The proxy server looks up the extracted keyword in the keyword-to-URL mapping to identify the URL of an application associated with the keyword. The proxy server constructs an HTTP POST operation containing the keyword and the URL, and submits the HTTP POST operation to the application over a wireline network such as the Internet. Upon receiving an HTTP response containing the requested content from the application in response to the POST operation, the proxy server extracts the content from the HTTP response.

International Classification:

G09G 5/00

US Classification:

715864, 715817, 715825, 345 11, 345 12

Abstract:

Techniques for displaying information on communication devices are disclosed. The techniques are highly beneficial for devices with relatively small viewing areas (e. g. , remote wireless phones). An enhanced communication device can be implemented which can dynamically display information on an associated display. This means that there is no need to reserve various areas on the display for displaying. Instead, information may be assigned or unassigned to the different display portions dynamically. As a result, the display area can be used more efficiently.

Abstract:

A seal having a body and several bands extending away from the body. The bands extend around an axial portion of the body. In some embodiments, the bands project from and are formed integral with the body. For example, the bands can be rings. Two bands can be located on the outside of the body and two additional bands can be located on the inside of the body to provide redundant sealing components between separated fluids. A vent aperture can be positioned between the two bands on each side of the body. The two inner bands can be offset from the two outer bands. The seal can be used in a surgical cutting device, among other things.

Abstract:

A memory card comprising a substrate, a memory die on top of the memory die, a controller die on top of the memory die; and a interposer surrounding the controller die and on top of the memory die wherein the interposer allows for wire bonding to the substrate to be minimized. A system and method in accordance with the present invention achieves the following objectives: (1) increase the density of the Flash card by reducing the number of wire bond pads on the substrate and enabling insertion of the largest die possible that can fit inside a given card interior boundary; (2) more efficiently stacks Flash memory dies when stacking is necessary, to increase density of the Flash card; (3) has only a few necessary signal I/O bonding wires to the substrate to improve production yield.
