20110072498 | TEARING AND CONFORMAL TRANSFORMATION HUMAN INTERACTIVE PROOF - The HIP creation technique described herein pertains to a technique for creating a human interactive proof (HIP) by applying tearing and/or a conformal transformation to a string of characters while maintaining readability of text. In one embodiment, the technique tears a character string into two or more pieces and applies conformal transformation to warp the pieces in order to create a HIP. The transformation changes the shape and orientation of the characters but preserves angles of the characters which makes it easy for humans to recognize the characters after the transformation. Other embodiments of the technique create HIPs by applying tearing only to a string of characters, or by applying conformal transformation only to the character string. | 03-24-2011 |
20110208716 | Image-Based CAPTCHA Exploiting Context in Object Recognition - Techniques for an image-based CAPTCHA for object recognition are described. The disclosure describes adding images to a database by collecting images by querying descriptive keywords to an image search engine or crawling images from the Internet. | 08-25-2011 |
20110283346 | OVERLAY HUMAN INTERACTIVE PROOF SYSTEM AND TECHNIQUES - The overlay human interactive proof system (“OHIPS”) and techniques described herein operate in conjunction with any known or later developed computer-based applications or services to provide secure access to resources by reliably differentiating between human and non-human users. Humans have a generally superior ability to differentiate misaligned characters or objects from correctly aligned ones. As such, the OHIP splits an image including one or more visual objects into two or more partial images to form a HIP. The partial images may also be further split into groups of sub-partial images, and/or the partial images (or the sub-partial images) may be moved, so that at any given alignment position, a user can recognize only some visual objects. A user is instructed to reassemble the partial images at one or more predetermined alignment positions using a GUI, and the user is asked to identify information regarding one or more visible objects. | 11-17-2011 |

20140208509 | CRADLE DRIVE MECHANISM, A TABLE, AND A PATIENT IMAGING AND CARRYING APPARATUS - A cradle drive mechanism, a table and a patient imaging and carrying apparatus are provided. The cradle drive mechanism includes: a first portion, which is arranged on a main base and has a belt drive structure, wherein the belt drive structure is used to connect a cradle and drive the cradle to make a reciprocating motion; a second portion, which is arranged on a secondary base and has a secondary supporting and rotating member, wherein the second portion and the first portion form a gap therebetween, and the secondary supporting and rotating member is used to support the cradle; and two guiding and rotating members, which are arranged on the second portion and/or the first portion for guiding the cradle to move linearly. The present application can simplify the structure by adoption of the belt drive structure. Further, the gap between the second portion and the first portion does not attenuate the X-ray additionally, so the dose of the X-ray emitted can be decreased. | 07-31-2014 |
20140328296 | METHOD AND APPARATUS FOR WIRELESS PEER-TO-PEER COMMUNICATION WITH MULTIPLE RADIO INTERFACES - Methods, apparatus, computer program products and wireless devices are provided for performing a wireless P2P communication application in a wireless device equipped with two or more radio interfaces. A method comprises establishing a first transport layer connection for transporting meta-information of a P2P communication application via a first radio interface; and establishing a second transport layer connection with at least one peer node for transporting data chunks of the P2P communication application by using a network address of a second radio interface, so that the data chunks can be transported via the second radio interface. | 11-06-2014 |
20150049665 | METHOD, APPARATUS, AND COMPUTER PROGRAM PRODUCT FOR ADAPTIVE RELAYING DATA DISTRIBUTION IN WIRELESS NETWORKS - Method, apparatus, and computer program product example embodiments enable data distribution in wireless communication networks. In example embodiments, a method comprises receiving a wireless broadcast message including a message ID and an associated distributor address; buffering the received wireless broadcast message and starting an observation window timer for the message if the message ID of the received wireless broadcast message is not stored in a database of message IDs and associated distributor addresses for previously received wireless broadcast messages; calculating a relaying probability for the received wireless broadcast message, based on a number of distributor address entries associated with the message ID in the database, the entries resulting from receiving other wireless broadcast messages having the same message ID during the observation window; transmitting the buffered message following termination of the observation window, based on the calculated relaying probability; and starting a cooling window timer upon termination of the observation window and removing all records containing the message ID from the database following termination of the cooling window. | 02-19-2015 |
