Abstract: Described herein are computerized methods and systems for detecting fraud during biometric identity verification. A mobile device captures video comprising a plurality of frames of a person's face. The mobile device extracts from the video frames comprising at least two frames of the person's face from different angles. The mobile device creates a reconstruction of the person's face using the extracted frames and derives signals associated with features of the person's face. The mobile device generates an embedding for each extracted frame using the extracted frames, the three-dimensional reconstruction, and the signals. The mobile device calculates, for each extracted frame, a fraud confidence value based upon the embedding for the extracted frame, attributes of the person's face, and image quality attributes of the extracted image. The mobile device computes a fraud detection decision for the extracted frames based upon the fraud confidence values and the embeddings.

Abstract: Scene tracker, for use with imaging or quasi-imaging sensors such as TV cameras, FLIRS, millimeter-wave scanners, or the like, which is concerned with a form of correlation tracking. At the start of a track mode, part or parts of a scene are stored in a memory (40). Every subsequent video scan (via 10,20,14) is then compared (50) with the scene or parts of the scene stored in memory (40) to find the "best match" between live data and stored data. This process generates (90) signal output (46) proportional to horizontal and/or vertical translations of the scene. Besides pure translation, the scene tracker is capable of tracking and original aim point in the presence of scene rotation, scene growth (zooming), scene reduction (dezooming), distortion, and/or partial scene obscuration. Features of the tracker include a multi-cell correlation principle; a method of computing and storing correlation functions for each cell; a method to derive weighted average displacements for the entities of all cell correlations; and video signal processing technique.

Abstract: An improved ceramic capacitive pressure transducer adaptable for use in automobiles is disclosed. The pressure transducer comprises a thin flexible diaphragm disc (22) having a capacitor electrode (24) deposited on it. A thick cylindrical base substrate (10) has a top surface (11) with a second capacitor electrode (19) deposited thereon and the diaphragm (22) is bonded to the top surface (11) of the base substrate (10) by an annular glass ring (16) such that the first and second electrodes (19, 24) are separated from each other and face each other directly across an air gap. The diaphragm, the top surface of the base substrate and the annular glass ring form an internal cavity (34) in which a reference vacuum is stored. In response to pressure changes outside of this cavity, the diaphragm (22) will flex and thereby change the capacitance created by the first and second electrodes. The base substrate (10) has an integral annular flange (21) laterally extending with respect to and beyond the top surface (11) of the base and located below the top surface (11) and between the top and bottom surfaces (11, 12). A sealing rubber 0-ring (38) is mounted on the flange and is used to sealingly mount the transducer to a housing wall (40) without applying stress to the diaphragm.

Abstract: A method for manufacturing billets intended to be subsequently machined into a desired shape by plastic deformation, as by rolling, includes the heating to a predetermined bonding temperature of powder grains enclosed in a capsule, and subjecting the capsule at the bonding temperature to a high pressure sufficient to bond the powder grains together to form a substantially solid body. The capsule is inserted at the bonding temperature into an over-sized forming cavity of a press which includes relatively movable punches, the capsule being completely surrounded within the press by a layer of heat-insulating and pressure-transmitting solid material, such as talc or the like. Thus, when the capsule is subjected to the high pressure upon operation of the press, such material serves as a pressure-transmitting medium through which pressure is applied completely against all sides of the capsule.

Abstract: In a ring communication system comprising several stations, access to the ring is granted to one station at a time by a circulating token indication. A method is provided guaranteeing a transmission opportunity for synchronous or circuit-switched data in periodic time intervals to authorized stations. A CS monitor station issues a frame header which is marked in a specific bit position to allow only authorized stations to transmit their synchronous data together with a destination address. In a first embodiment, a single frame comprises a plurality of slots each having a free/busy indication, a destination address field and a field for synchronous data, and each authorized station can occupy one such slot. In a second embodiment, a marked frame can be used by only one authorized station for transmitting synchronous data, but a new marked frame header is reissued until all authorized stations around the ring have transmitted synchronous data.
