| 20100229950 | Ionic Liquid Electrolyte - The present invention relates to electrolytes comprising tetracyanoborate and an organic cation as components of electrolytes in electrochemical and/or optoelectronic devices, in particular solar cells. This ionic liquid has low viscosity and can be used as electrolyte in the absence of a solvent. Importantly, the ionic liquid remains stable in solar cells even after prolonged thermal stress at 80° C. for 1000 hours. Photovoltaic conversion efficiency remained stable and keeping more than 90% of the initial value. | 09-16-2010 |

| 20120068353 | Semiconductor Device and Method of Forming Dam Material With Openings Around Semiconductor Die for Mold Underfill Using Dispenser and Vacuum Assist - A semiconductor wafer contains a plurality of semiconductor die separated by saw streets. A dam material is formed over the saw streets around each of the semiconductor die. A plurality of openings is formed in the dam material. The openings in the dam material can be formed on each side or corners of the first semiconductor die. The semiconductor wafer is singulated through the dam material to separate the semiconductor die. The semiconductor die is mounted to a substrate. A mold underfill is deposited through a first opening in the dam material. A vacuum is drawn on a second opening in the dam material to cause the underfill material to cover an area between the first semiconductor die and substrate without voids. The number of second openings can be greater than the number of first openings. The first opening can be larger than the second opening. | 03-22-2012 |

| 20100199086 | NETWORK TRANSACTION VERIFICATION AND AUTHENTICATION - A two-level authentication system is described supporting two-factor authentication that offers efficient protection for secure on-line web transactions. It includes a global unique identity (UID) provided either by an institute-issued/personal trusted device, or based on client computing platform hardware attributes, and generated using institution authorized private software, institution-authorized authentication proxy software, and an institution-generated credential code which is pre-stored in the token and only accessible by the institute-authorized authentication proxy software. The institution-authorized authentication proxy software uses the user's PIN and the trusted device's UID as input and verifies the user and device identities through institution-generated credential code which was pre-stored in the trusted device. Authentication is performed in two levels: the first authenticates the user and the trusted device locally; and the second authenticates the user remotely at the institution-owned authentication server. Various embodiments add extra levels of security, including one-time-password management. | 08-05-2010 |
| 20100239092 | METHODS AND SYSTEMS FOR COMMUNICATING OVER A QUANTUM CHANNEL - Alice generates a sequence of key bits forming an initial cryptographic key. Alice then uses the sequence of key bits and a sequence of cipher bits to control respective control parameters of a quantum encoding process applied to a sequence of quantum pulses, where the sequence of cipher bits used is known to Bob. Alice then releases the encoded pulses towards Bob over a quantum channel. Bob uses the previously agreed-upon sequence of cipher bits to control a control parameter, such as the quantum basis, of a quantum detection process applied to the pulses received from Alice, thus producing a detection outcome for each received pulse. Bob then derives a final cryptographic key from the detection outcomes. Because the cipher bits used to select the quantum bases used by both Alice and Bob are known by both parties, the method allows the final cryptographic key to be distributed with full basis alignment compared to 50% for BB84, thus allowing efficient quantum key distribution over multiple hops. | 09-23-2010 |
| 20110154459 | METHOD AND SYSTEM FOR SECURING ELECTRONIC TRANSACTIONS - A method for secure electronic transaction over a computer network, comprising: at a trusted relationship profile server computer: storing a unique identity of a trusted computing unit; generating a confirmation message regarding the unique identity of the trusted computing unit in response to a request from the trusted computing unit; at a security proxy server computer: storing real credentials and local credentials of a customer in a secure vault; receiving the confirmation message and permitting a login process to be performed with the security proxy server using the local credentials, provided the confirmation message is valid; and replacing the local credentials submitted in the login process with the real credentials. A corresponding system for secure electronic transactions is also provided. | 06-23-2011 |

| 20090140808 | GAIN CONTROL CIRCUIT - A gain control circuit including a resistor with a first terminal and a second terminal; an operational amplifier with an inverting terminal thereof electrically coupled to said first terminal of said resistor; a non-inverting terminal thereof; and an output terminal thereof; an amplifier circuit for transforming the voltage change of said operational amplifier output into a substantially exponential current change; wherein the output of said amplifier circuit is electrically coupled to said inverting terminal of said operational amplifier. The above described gain control circuit is able to perform wide bandwidth input signal buffering with linearity under low voltage and low power conditions. The circuit also offers low output impedances without the need of additional buffers and hence minimizing circuit size and manufacturing costs. | 06-04-2009 |
