| 20080277196 | Engine and technique for generating an acoustic signal - A device for generating an acoustic signal in a fluid includes an engine operable to repeat a thermodynamic process to vibrate a membrane of the engine to generate an acoustic signal having more than one period. The thermodynamic process includes heating mass inside a chamber of an engine to generate pressure inside the chamber; in response to generating the pressure, moving in a first direction a portion of a membrane of the engine; removing mass from inside the chamber to decrease the pressure inside the chamber; and in response to decreasing the pressure inside the chamber, moving the membrane portion in a second direction. Because the engine repeats the thermodynamic process, the engine can generate and sustain an acoustic signal for a significant amount of time. In addition, because the heat in the engine's chamber is generated by a chemical reaction, the engine may quickly generate a significant amount of pressure inside the chamber to quickly accelerate the membrane, and thus generate a powerful acoustic signal. Furthermore, various properties of the membrane and/or the thermodynamic process may be modified to tune the acoustic signal to a desired frequency and/or amplitude. Thus, the engine may be effectively used to generate acoustic signals for a number of different purposes, such detecting and ranging objects in a region, and in a number of different marine environments, such as a littoral environment that contains a large amount of noise, or a deep sea environment at high water pressure. | 11-13-2008 |

| 20090094379 | Apparatus and Method for Web Forwarding - An apparatus and method for forwarding a web address to another web address is presented. A web forwarder receives a request destined to a first web address including at least a domain name. The web forwarder then determines a forwarding uniform resource locator (URL) that corresponds to the domain name and redirects the request to a second web address that corresponds to the forwarding URL. | 04-09-2009 |

| 20090162557 | NANOSCALE METAL PASTE FOR INTERCONNECT AND METHOD OF USE - A paste including metal or metal alloy particles (which are preferably silver or silver alloy), a dispersant material, and a binder is used to form an electrical, mechanical or thermal interconnect between a device and a substrate. By using nanoscale particles (i.e., those which are less than 500 nm in size and most preferably less than 100 nm in size), the metal or metal alloy particles can be sintered at a low temperature to form a metal or metal alloy layer which is desired to allow good electrical, thermal and mechanical bonding, yet the metal or metal alloy layer can enable usage at a high temperature such as would be desired for SiC, GaN, or diamond (e.g., wide bandgap devices). Furthermore, significant application of pressure to form the densified layers is not required, as would be the case with micrometer sized particles. In addition, the binder can be varied so as to insulate the metal particles until a desired sintering temperature is reached; thereby permitting fast and complete sintering to be achieved. | 06-25-2009 |

| 20090213001 | Dynamic Location of a Subordinate User - Providing location information to a supervisory user includes providing a parental control, using a computer automatically to determine a location of a subordinate user, and storing location information indicative of the location of the subordinate user in a database. A request of the supervisory user to locate the subordinate user is received and a user interface informs the supervisory user of the location of the subordinate user based on the stored location information. At least one of the storing and/or the informing are based on the parental control. | 08-27-2009 |
| 20100122190 | CALENDAR OVERLAYS - Implementing an electronic calendar can include accessing a first electronic calendar owned by a first party, accessing a second electronic calendar owned by a second party, and presenting a view that combines at least one existing entry from within each of the first and second electronic calendars. Source information for each of the first and second electronic calendars may be electronically maintained. The combined view may be updated electronically to reflect a change to at least one of the existing entries from within at least one of the first and second electronic calendars. Electronic calendars may be accessed and overlaid without importing events, thus enabling simple updating. Event information may be imported and source or other attributes may be associated with imported information to enable updating and other sorting functions. | 05-13-2010 |

| 20090003315 | METHODS AND APPARATUS FOR DUAL-TONE MULTI-FREQUENCY SIGNAL CONVERSION WITHIN A MEDIA OVER INTERNET PROTOCOL NETWORK - In one embodiment, a method includes receiving a first internet protocol (IP) packet having information associated with a dual-tone multi-frequency (DTMF) signal. The information of the first IP packet is configured based on a protocol associated with a first layer of a media over internet protocol (MoIP) network. The first IP packet is associated with a destination endpoint. The method also includes producing a second IP packet having information associated with the DTMF signal. The information of the second IP packet is configured based on a protocol associated with a second layer of the MoIP network and a DTMF conversion policy associated with the destination endpoint. The second layer is different than the first layer. | 01-01-2009 |
