| 20080299174 | Bis-(Alpha-Amino)-Diol-Diester-Containing Poly (Ester Amide) and Poly (Ester Urethane) Compositions and Methods of Use - The present invention provides biodegradable, biocompatible bis-(α-amino acyl)-diol-diester-containing poly(ester amide) (PEA) and poly(ester urethane) (PEUR) co-polymer compositions with mechanical properties that can be readily tailored by selection of various combinations and proportions of the building blocks of the co-polymers. The compositions are suitable for use in production of drug-releasing biodegradable particles and implantable surgical devices, such as stents and internal fixation devices. The co-polymer compositions, particles and surgical devices biodegrade in vivo by enzymatic action to release bioactive agents in a controlled manner over time as well as biocompatible breakdown products, including one to multiple different amino acids. | 12-04-2008 |

| 20110089479 | SCALABLE FLASH EEPROM MEMORY CELL WITH FLOATING GATE SPACER WRAPPED BY CONTROL GATE AND METHOD OF MANUFACTURE - A polysilicon spacer as a floating gate of a Flash memory device. An advantage of such spacer structure is to reduce a cell size, which is desirable for state-of-the-art Flash memory technology. In a preferred embodiment, the floating gate can be self-aligned to a nearby and/or within a vicinity of the select gate of the cell select transistor. In a preferred embodiment, the present invention preserves a tunnel oxide layer after the removal, using dry etching, a polysilicon spacer structure on the drain side of the select transistor gate. More preferably, the present method provides for a certain amount of tunnel oxide to remain so as to prevent the active silicon area in the drain region of the memory cell from being etched by the dry etching gas. | 04-21-2011 |

| 20090190475 | METHOD OF PRIORITIZING USER THROUGHPUT AND USER THROUGHPUT LIMITS FOR BEST-EFFORT APPLICATION IN cdma2000 1xEV-DO WIRELESS COMMUNICATION SYSTEM - The present invention provides a method implemented in a mobile unit configured to communicate with at least one base station over an uplink. The method includes receiving, at the mobile unit and from the base station, a first attribute indicative of a traffic-to-pilot power ratio and a second attribute indicative of a resource provision limit. The first attribute is formed based on a priority weight associated with best effort communication with the mobile unit. The second attribute is formed based on a maximum throughput associated with best effort communication with the mobile unit. The method also includes modifying an uplink transmission power based upon the first attribute and information indicative of congestion at the base station. | 07-30-2009 |
| 20110312355 | METHOD OF CANCELLING INTERFERENCE IN SOUNDING REFERENCE SIGNALS - The present invention provides a method of interference cancellation. Embodiments of the method may include removing one or more first reference signals from a signal received by a first base station to form a modified signal. The signal includes a superposition first reference signal(s) transmitted by first user equipment served by the first base station and one or more second reference signals transmitted by second user equipment served by a second base station. The method may also include extracting the second reference signal(s) from the modified signal and determining a timing delay between the second user equipment and the first base station using the extracted second reference signal(s). | 12-22-2011 |

| 20110184790 | Actionable Digital Cards, Related Content and Social Marketing - The invention is a system and method for creating, managing and delivering actionable digital cards and related content to mobile devices. The system measures penetration of cards and provides measurable marketing, such as which consumer viewed which content. It allows an owner of a mobile device to acquire, manage, and act on actionable digital cards giving them the benefit of being able to acquire a large number of cards, their associated loyalty points, rewards, and any savings associated with related content. Further, it supports social marketing allow cards and related content to be recommended from person to person; benefiting all parties, whereby, individuals are made aware of cards and related content in a non-disruptive manner and enterprises are able to market their products and services through social marketing or “word-of-mouth” type advertising. | 07-28-2011 |
