Title: Security access system.
Inventor: BLACK GERALD R
IPC: G06F3/0354
Filed: 2002-05-28
Abstract: This identity authentication system is used in commercial transactions at a point-of-sale terminal. The system comprises a device for capturing a customer signature (signature pad or a smart pen), a sensor for capturing a biometric property of the customer during the transaction, a local processor, a wireless device carried by the customer, a device reader positioned at the point-of-sale terminal, and a host computer. The customer registers advising the system of a customer account that is to be used for payment. The customer also submits an electronic signature (written script of name) and a digital signature for reference purposes - a fingerprint. The customer is then issued a wireless device, the wireless device having memory. The memory may be an ID card, a credit card, a smart card, a transponder, a barcode, or a combination of these memories. An identifying device reader (such as a card reader, an interrogator, a scanner) is located at the point-of-sale terminal that is compatible with the wireless device. Thereafter, when the customer uses a stylus to submit written data - an electronic signature is generated. Similarly, a sensor in the stylus captures data that is used to generate a digital signature. A reference print is then accessed through the memory in the wireless device carried by the customer. The digital and electronic signatures are then compared against the reference data to authentic identity.

Title: Safety support for an interior mirror of a vehicle, and support assembly method.
Inventor: ALFONSO CASTANO BAJO
IPC: B60J3/02
Filed: 2004-11-10
Abstract: A safety support for an interior mirror of a vehicle, comprising a rigid bearing plate for a mirror and a frame. The bearing plate has two major surfaces, a front surface, intended for receiving the mirror, and another rear surface, which can bearing reenforcement ribs. The bearing plate is fixed to the frame such that the bearing plate with the mirror does not separate from the frame during operational use, but does separate from the frame when a force exceeding a certain threshold is exerted on the front surface of the bearing plate. The fixing allow that if a force is exerted on the mirror that could break it, the bearing plate and the mirror solidly fixed to the former can separate from the frame and move in a first direction with regard to the frame. There may also be an electric circuit integrated on the bearing plate. Also an assembly method for assembling this support.

Title: Method and system for communicating content on a broadcast services communication system.
Inventor: MALLADI DURGA P
IPC: H04B7/26
Filed: 2003-08-15
Abstract: An outer decoder and an inner decoder encode a block of information to be transmitted, to improve protection by adding redundancy. The redundancy permits decoding of the information from less than a complete encoded block of information. Time re-alignment of two transmissions of the same content from two base stations can mitigate the problem of duplicated frames. The user of the subscriber station can experience seamless service without repetition of content, even when handing over to a new cell while receiving a buffer of broadcast content.

Patent MX-PA05010184-A (MX)
Title: Contention-based forwarding with integrated multi-user detection capability.
Inventor: JOHANSSON NIKLAS
IPC: H04W84/18
Filed: 2004-03-17
Abstract: A basic idea is to employ multi-user detection (MUD) at the receiver side in a multi-hop network to concurrently decode multiple packets transmitted from multiple nodes (T1, T2), and prioritize among the correctly decoded packets to select one or more packets suitable for forwarding, and finally reply with a packet acknowledgement (ACK) to the corresponding transmitting node for each selected packet. In this way, the design choice of MUD is exploited in the forwarding procedure. It is furthermore beneficial to exploit also the diversity enabled by the existence of multiple relay nodes (R1, R2, R3). A transmitting node that transmits its data packet signal to multiple relay candidate nodes and then receives packet acknowledgements from at least two relay candidate nodes preferably performs a prioritization to select a suitable relay node. The transmitting node then transmits a forwarding order (FO) to the selected relay node, which takes on responsibility for forwarding the information to the next node.
Patent MX-PA05011800-A (MX)
Title: Method and arrangement for loop test of a disturbed line.
Inventor: ROSENBERG JONAS
IPC: G01V1/00
Filed: 2004-04-08
Abstract: The invention refers to single-ended test of a loop (2, 3). A test device (TD1) is connected to a remote device (3) via a line (2). The remote device is powered on and transmits intermittently handshake signals (HS1), which can disturb the loop test. A receiving and calculating unit (RE1) detects the handshake signals (HS1) and orders a sending unit (SD1) to send a halting signal (NAK-EF) to the remote device. The latter is halted for predetermined silent period of time, during which the test or a part of it is performed. If required the halting of the handshake signals is repeated. The test device sends a broadband loop test signal (S1) and receives a reflected signal (S2) during the silent period. A frequency dependent echo transfer function is generated from the signals (S1, S2) and is used for generating desired properties of the line (2) such as its length (L).

Abstract: A seismic streamer includes a jacket covering an exterior of the streamer. At least one strength member extends along the length of the jacket. The strength member is disposed inside the jacket. Seismic sensors are disposed at spaced apart locations along the interior of the jacket. A flexible, acoustically transparent material fills the space inside the jacket. The material is introduced into the inside of the jacket in liquid form and undergoes a state change thereafter. The strength member, prior to and during the state change, is maintained in substantially a same position with respect to the jacket as would occur during ordinary operation of the streamer. The maintaining position is performed at least at a location along the jacket where a device is to be coupled externally to the jacket.
