Title: Key signal generation from a sequence of images
Inventor: THOMAS GRAHAM ALEXANDER
IPC: G06V10/28
Filed: 2003-05-20
Abstract: Methods and apparatus for deriving a key signal from a sequence of images comprising foreground and background portions are described. Reference image data is determined corresponding to at least one reference image and at least one region is identified in an image. Different rules for generating the key signal are applied inside and outside of the identified region. In one embodiment the region is identified based on differences between the image and the reference image and the reference image data is updated in response to differences between successive images and the reference image so that the reference image approximates the successive images while inhibiting updating of the reference image in the identified region. In another embodiment, an area of shadow is identified in an image and different key generation rules are applied within the shadow region to the rules used outside the shadow. Independent claims are also included for selecting target pixels for filling using identified test pixel pairs along test pixel lines, deriving a key signal for a sequence of images using reference image data wherein the reference image includes local noise data and deriving a key signal for a sequence of images using reference image data wherein the reference image is derived from a plurality of images and includes a mean value and a measure of variance for each pixel of the reference image.

Title: Customized program creation by splicing server based video, audio, or graphical segments
Inventor: LIGA KEVIN
IPC: H04N7/24
Filed: 2002-01-18
Abstract: A customized programming creation (100) system provides the ability to transmit customized programming offerings to individual users based upon their known profile (136) or their responses to contemporaneous queries. The invention provides for a programming transmission center (102) to maintain a single or multiple MPEG storage server (214) environments storing a vast library of programming and other information signals. The transmission center (102) selects and accesses programming segments or other information from the storage servers (214). Through the use of splice points encoded through the MPEG process, the programming transmission center (102) can inconspicuously splice disparate program segments together to create a single custom program stream (104) for delivery to a single user or multiple users of the same profile.

Inventor: HSU CHING-HSIANG
IPC: H04W8/06
Filed: 2003-11-28
Abstract: In an island type mobile communication arrangement is disclosed. A plurality of BTSs connected to BSCs are reassigned as island BTSs (39, 49, 59) and connected to an island BSC (66), the island BSC is connected to an island MSC (85). When entering or leaving the scope of the island MSC, a cellular phone (20) performs a location updating procedure, and thus the island type mobile communication arrangement can provide a special service to all cellular phones in a particular local area by reading MSISDNs in an island VLR (67) corresponding to the island MSC. In effect, the BSC controls several BTS's which may be geographically separate. For instance, a chain of shops could add BTS's to the island BSC corresponding to locations of their shops and offer discounts to mobile users within those areas.

Title: Pair of pull rollers for a rotary printing machine
Inventor: THEILACKER KLAUS
IPC: B65H20/02
Filed: 2004-12-16
Abstract: A pair of pull rollers in a rotary printing machine, in particular an offset rotary newspaper-printing machine, consists of two driven pull rollers 7, 9. A ribbon consisting of a plurality of print-carrier webs 2, 3 is guided through between the pull rollers, with one of the pull rollers 9 having the ribbon 1 partially wrapped around it. Different web paths follow as a result of this. The difference in path, and hence speed, is greatest between the innermost and outermost print-carrier webs 2, 3. In order to achieve different conveyance characteristics in relation to the upper and lower side of the ribbon so that the webs can be fed to the downstream units at substantially the same speed and thus with the same tautness, one of the pull rollers, namely the inner pull roller 9 that has the inside web wrapped round it, is driven at a higher surface speed than the pull roller 7 that is in contact with the outer web. With the diameters of the rollers being identical this can be done by driving them at different rotational speeds. Alternatively, it is also possible to drive both pull rollers 7, 9 at the same rotational speed, with the diameter of the wrapped pull roller 9 being slightly greater than the diameter of the other pull roller 7 so that a greater circumferential speed results for the inner pull roller 9.

Title: An efficient class B RF amplifier with supply voltage modulation
Inventor: FRIEDLANDER HAIM
IPC: H03F1/02
Filed: 2005-04-22
Abstract: The dc collector or drain current of class B amplifying transistor 101 is detected by a sense resistor 108 and differential amplifier 112. The output voltage Vcc of the switching regulator 107 is controlled to be in proportion to the sensed current so that the amplifier operates slightly below saturation at all input power levels. In a class B amplifier, the DC supply current is proportional to the output RF power level. The amplifier may be used in mobile or base stations. The technique avoids the effect of transistor variations with time or variations between devices. There is no need to calculate the power envelope from in-phase and quadrature data and there is no need to compensate for inherent delays to achieve matching of the supply voltage and the RF power envelope.

Title: Decrypting web mail session key/signing document at trusted third party server so that recipient private key is not used at vulnerable computer
Inventor: DANCER ANDREW
IPC: H04L9/08
Filed: 2006-02-02
Abstract: There is described an electronic data communication system in which encrypted mail messages for a recipient are sent in two parts: message data encrypted by a symmetric encryption algorithm using a session key and session key data encrypted by an asymmetric encryption algorithm using a public key associated with the recipient. If the recipient uses a webmail service to access the encrypted electronic mail message, the encrypted session key data is sent to a trusted third party server which has access to the private key of the user. The trusted third party server decrypts the encrypted session key using the private key of the user, and then sends the decrypted session key to a remote network device for decryption of the encrypted message. In this way, although the trusted third party has access to the private key of the user, the trusted third party does not have access to any decrypted message. In another aspect, in order to digitally sign a message, the sender applies a hash function to the message to generate a hash value, and then sends the hash value to the trusted third party server where it is encrypted using the private key associated with the sender in order to generate the digital signature, which is then returned to the sender.
