A gaining hosting provider may sign DNS records of the domain with the gaining hosting provider DNSKEY prior to transferring the domain from the losing hosting provider to the gaining hosting provider. Additionally, a registry server, or similar device, may be configured to act as an intermediary between the losing hosting provider and the gaining hosting provider during the transfer process. | 10-04-2012 |
| 20120278626 | DNSSEC Inline Signing - Systems and methods of performing incremental DNSSEC signing at a registry are described in which digital signature operations may be performed as part of a single transaction including DNS add, update, and/or delete operations and the like. Exemplary methods may include receiving a domain command from a requester, the domain command including an identifier of a domain. The received domain command may be executed with respect to data stored by the registry for the domain. As part of an individual transaction including the execution of the domain command, the registry may also sign DNSSEC records for the domain using a private key of an authoritative server. After the DNSSEC records have been signed, the registry may incrementally publish the signed DNSSEC records to a separate server. Exemplary methods may also include “took-aside” operations in which, for example, add, update, and/or delete operations may be executed on data stored in a registry database and reported to a requester, prior to applying digital-signatures to the DNSSEC data. After reporting that the instructions have been executed, the registry may generate a digital signature based on the add, update, and/or delete changes, and commit the digital signature to a registry resolution database. | 11-01-2012 |
| 20120284505 | DNSSEC SIGNING SERVER - Systems and methods for performing DNSSEC signing are described in which digital signature operations may be performed by a network accessible signing server that is configured to interact with a separate client application. Exemplary methods may include receiving a signing request at the signing server from the client application to sign first data. The signing server may determine an active KSK and/or an active ZSK for the first data. The first data may then be transmitted by the signing server to a digital signature modules, which may include, for example, a hardware support module, or software signing applications. The signing server may receive a digitally signed version of the first data from the digital signature module, and provide the signed first data to the client application. | 11-08-2012 |

| 20120263056 | APPARATUS, METHODS, AND ARTICLES OF MANUFACTURE FOR WIRELESS COMMUNICATIONS - Selected embodiments are directed to methods, apparatus, and articles of manufacture for wireless radio frequency communications. Adjacent antenna array elements of a receiver antenna array are separated by less than the diffraction limit of the radio frequency communication band in which the apparatus and methods operate. A plurality or multiplicity of near-field scatterers are asymmetrically placed in the immediate vicinity of each of the antenna array elements, to perturb the pattern of each of the antenna elements, making the patterns different even below diffraction limit spacing. A transmitter spatially and temporally focuses simultaneous transmissions on each of the antenna array elements, using time reversal communication techniques. The transmitter may transmit through multiple antenna elements, and the channel from the transmitter to the receiver may be subject to multipath phenomena. | 10-18-2012 |

| 20120328037 | ANTI-GEOLOCATION - Methods, apparatus, and articles of manufacture make Geolocation of a source transmitter more difficult or impossible. Scatterers common to a source transmitter and an intended receiver are identified using a variety of techniques, such as iterative time reversal (ITR) and Singular Value Decomposition (SVD) of a scatter matrix. The source transmitter then uses time reversal and knowledge of the signatures of the scatterers to focus its transmissions on one or more of the scatterers, instead of the intended receiver. The source transmitter may have multiple antennas or antenna elements. The source transmitter and/or the intended receiver may include antenna elements with Near-Field Scatterers to enable spatial focusing below the diffraction limit at the frequencies of interest. The source transmitter may be a plurality of ad hoc nodes cooperating with each other. | 12-27-2012 |

| 20130014552 | Electronically-Controlled Removable Core Lock - An electronic small format interchangeable core (“SFIC”) lock is configured so that core locking features are electronically controlled, and keys can be electronically programmed to operate either as a normal user key able to open the lock or as a control key able to open the lock and to remove the SFIC cores. The same key will operate as a normal access key or as a control key, depending on how the key is programmed. | 01-17-2013 |

| 20130041352 | Self-Cleansing Bladder Drainage Catheter - An indwelling endourethral drainage catheter includes a tubular distal portion and a spiral first portion. A central lumen extends along substantially the entire length of the catheter. The spiral first portion defines an outer spiral channel in fluid communication with the central lumen. The distal end of the catheter is anchored externally so that the catheter is held against advancement into or out of the urethra. In certain methods, the diameter of the spiral first portion may be changed to address obstructions within the urethra or facilitate navigation of the catheter along the urethra. | 02-14-2013 |
