IPC: G02B6/122
Filed: 1998-08-24
Abstract: An optical pulse amplifier. The optical pulse amplifier includes: a first optical coupler having first, second, third and fourth ports, for outputting an optical pulse incident onto the first port to the second and third ports, and the optical pulse re-incident from the second and third ports to the fourth port; a first grating connected to the second port of the first optical coupler, for reflecting the incident optical pulse for each wavelength at a position satisfying the Bragg condition; a second grating connected to the third port of the first optical coupler and having the same optical characteristics as the first grating, for reflecting the incident optical pulse for each wavelength at a position satisfying the Bragg condition; an optical amplifying portion connected to the fourth port of the first optical coupler, for amplifying the optical pulse reflected by the first and second gratings and output by the fourth port of the first optical coupler; and a second optical coupler having first, second, third and fourth ports, for outputting the optical pulse incident from the optical amplifying portion connected to the first port to the second and third ports respectively connected to the first and second gratings, and the optical pulse re-incident after being reflected by the first and second gratings to the fourth port. Therefore, non-linear effect and spectral hole burning effect can be avoided through amplifying and broadening of the optical pulse, and there is less diffraction loss and manufacturing the optical pulse amplifier is easy.

Title: Decoder utilizing soft information output to minimize error rates
Inventor: KHAYRALLAH ALI S
IPC: H03M13/45
Filed: 1997-08-13
Abstract: A coding system is disclosed wherein the receive side includes a decoder capable of producing, in addition to the hard information decoded output, either or both symbol and/or bit soft information values. For a certain information bit position, a value proportional to the joint probability that a received symbol and the set of all hypothesized transmitted codewords led to the estimated or detected hard information output is calculated. The calculated probabilities with respect to plural codewords having a zero in that certain information bit position are compared to the calculated probabilities with respect to the plural codewords having a one in that certain information bit position. The result of the comparison provides an indication of whether the hard information output in that same information bit position is more likely a one or a zero. The output soft information values are further processed in comparison to a preset threshold, with instances exceeding the threshold triggering block rejections and/or retransmissions.

Title: Outside access to computer resources through a firewall
Inventor: MOORE VICTOR STUART
IPC: H04L12/56
Filed: 1997-10-02
Abstract: A firewall isolates computer and network resources inside the firewall from networks, computers and computer applications outside the firewall. Usually, a firewall allows for an inside user or object to originate connection to an outside object or network, but does not allow for connections to be generated in the reverse direction; i.e. from outside in. The disclosed invention provides a special "tunnelling" mechanism, operating on both sides of a firewall, for establishing such "outside in" connections when they are requested by certain "trusted" individuals or objects or applications outside the firewall. The mechanism includes special tunnelling applications, running on interface servers inside and outside the firewall, and a special table of "trusted sockets" created and maintained by the inside tunnelling application.

Title: Vertically pleated diaper liner
Inventor: SCHLINZ DANIEL R
IPC: A61F13/494
Filed: 1997-12-18
Abstract: An absorbent article such as a diaper includes a backsheet layer, a substantially liquid-permeable liner layer, and an absorbent body located between the backsheet and the liner. The backsheet and liner layers generally define a front waistband section, a rear waistband section, and an intermediate section, with the intermediate section interconnecting the front and rear waistband sections. The liner includes a plurality of spaced apart longitudinal upstanding ridges located at least in the intermediate section to provide barriers to transverse migration of body exudates. The upstanding ridges are formed by providing a plurality of laterally spaced apart and alternating longitudinally adhered liner portions and unadhered liner portions. Elastic members are located subjacent the unadhered portions and include a front end, a rear end, and a central portion disposed between the front and rear ends. The front and rear ends are in a relaxed state while the central portion is in an elastically contractible condition to cause the liner to gather and stand-up to be spaced away from the absorbent structure when the article is placed on the wearer.
