Title: Compensating for chromatic dispersion in optical fibers
Inventor: CHEN YONG QIN
IPC: H04B10/2525
Filed: 2003-07-15
Abstract: An optical chromatic dispersion compensator (60) betters optical communicati on system performance. The dispersion compensator (60) includes a collimating means (61) that receives a spatially diverging beam of light from an end of an optical fiber (30). The collimating means (61) converts the spatially diverging beam into a mainly collimated beam that is emitted therefrom. An optical phaser (62) receives the mainly collimated beam from the collimating means (61) through an entrance window (63), and angularly disperses the beam in a banded pattern that is emitted from the optical phaser (61). A light- returning means (66) receives the angularly dispersed light and reflects it back through the optical phaser (62) to exit the optical phaser near the entrance window (63) thereof.

IPC: H04L12/56

Abstract: To mitigate re-syncs, RLP sync control frames associated with a packet data session can be sequence numbered. A single sequence number can be assigned for an entire sync procedure associated with the initiation of a packet data session. For example, the sequence number can remains the same on all sync control frames (SYNC, SYNC/ACK, ACK) of a particular packet data session. When a sync frame is received out of order within a single sequence, it can be ignored under certain conditions. For example, if a SYNC frame with a sequence number 0 is received out of order after an ACK frame with sequence number 0 is received, the mobile station can ignore the out of order SYNC frame. Thus, an RLP re-sync is avoided due to out of order RLP sync packets.

Title: Compact single lens laser system for object/vehicle presence and speed determination
Inventor: SEAS ANTONIOS
IPC: G01S17/10
Filed: 2005-06-28
Abstract: A compact system for determining the presence and speed of an object/vehicl e, and its application for Red Light Camera photo-enforcement is disclosed. The disclosed system uses accurate timing, laser radiation in the form of optical pulses, and the scattering effect of optical pulses from the road or vehicle surface to determine the presence of a vehicle, and estimate its speed. The system can determine whether an object/vehicle is present at a specific location, estimate its height, and i n the case that the object/vehicle is moving, the system can estimate its speed. Combining the disclosed technology with commercially available digital recording techniques and equipment, a traffic photo-enforcement system can be constructed. The system is capable o f monitoring traffic in an intersection/highway, measure vehicle speed, identi fy potential traffic violations, and trigger a visual recording device such as a camera o r video system for documenting a violation. The system can serve as a tool by law enforceme nt agencies and research groups for other applications, such as measurement of traffic density, monitor vehicle speed, and the study of traffic patterns. Other important information that can be generated from the disclosed system is the profile of a moving object/vehicle, the length of the moving object/vehicle, and whether the moving object/vehicle w as accelerating or decelerating. Further analysis of the recorded data can yiel d information relevant to the make and model of the passing vehicles.

Title: Method for advertising
Inventor: PECK GORDON SIDNEY
IPC: G09F23/06
Filed: 2005-07-07
Abstract: A novel method for advertising is disclosed which has a consolidator obtaining rights from tabletop owners to place advertisements on their tabletops.  Preferably, the tabletop owners also agree to place and maintain the advertisements provided by the consolidator, but the consolidator can provide its own placement and maintenance service if the tabletop owners are unwilling or unable to provide such service. Once the consolidator has obtained the necessary rights from the tabletop owners, the consolidator can lease the space on the tabletops to advertisers, or their agents. The consolidator can manufacture the specific advertisements for the advertiser, or can provide specifications for the advertiser to have their ads manufactured to. Preferably, the ads employed are manufactured to reasonably survive their expected placement time despite the likelihood that they will be exposed to food and/or beverage spills. Accordingly, advertisements printed on plastic materials, or laminated with plastic materials, are preferred.

Title: Categorization of host security levels based on functionality implemented inside secure hardware
Inventor: MEDVINSKY ALEXANDER
IPC: G06F21/00
Filed: 2004-01-14
Abstract: A system for rating security levels a device according to the characteristics of functions executing within secure hardware components in the device. The security level of a host is placed in a digital certificate along with a corresponding private key at the time of manufacture of a device. The digital certificate can be provided to an inquiring device so that more comprehensive systme-wide security levels can be communicated and maintained. Where a network uses ticket-based key management protocols, the security rating, or level, is transferred from the certificate to an issued ticket. Inquiring devices can then check security levels of target devices by using certificates or tickets and perform transfers or grant authorizations accordingly. In a preferred embodiment a security ratings system uses six levels of security.  The levels are structured to include characteristics about a device~s processing. That is, the levels provide information on the amount and type of sensitive processing that can occur in non-secure (or low security) circuitry or components within a device. This gives a bette indication of how prone a device is to threats that may be of particular concern in content delivery networks. Additional qualifiers can be optionally used to provide further information about a security level. For example, the degree of handling time management processing within secure hardware and whether a particular codec, watermarks of fingerprings are supported within secure hardware can each be represented by a policy qualifier.
