Title: System and method to inform a radio telecommunications network of the operating capabilities of a mobile terminal located therein
Inventor: LUPIEN FRANCIS
IPC: H04W8/18
Filed: 1997-12-12
Granted: 2008-10-07
Abstract: A method in a cellular telecommunications network of informing the network (12) of a plurality of operating capabilities of a mobile terminal (11). The method begins with the steps of entering an access (intermediate) state at the mobile terminal and then transmitting a message (14) from the network to the mobile terminal requesting the mobile terminal to transmit information regarding the operating capabilities of the mobile terminal. The capability request (14) may be sent on a paging channel (PCH) or an access response channel (ARCH). This is followed by transmitting a capability report (15) from the mobile terminal to the network, the capability report including the requested information. The capability report may include all of the capabilities of the mobile terminal, or may include a specified capability set. The method may optionally include the step of determining whether the network has been informed of the operating capabilities of the mobile terminal before transmitting the message from the network to the mobile terminal requesting the mobile terminal to transmit its capabilities information. Additional capabilities, or updated capabilities may be retrieved from the mobile terminal by later transmitting a capability update request (17) to the mobile terminal.

Title: Method and apparatus for transmitting mpeg video over the internet
Inventor: BOYCE JILL MACDONALD
IPC: H04N7/24
Filed: 1999-09-02
Granted: 2003-07-01
Abstract: In order to transmit an inter-frame coded video signal, such as an MPEG-coded video signal, over a packet-based network such as the Internet, the video signal associated with at least one video frame, is split into a high priority partition and a low priority partition. A systematic forward error/erasure correction (FEC) code, such as a Reed Solomon (n,k) code, is then applied to bytes in the high priority partition. The forward error/erasure corrected high priority partition information bytes and the low priority partition information bytes are then combined into n packets for transmission over the packet network to a receiver/decoder. Each of the n transmitted packets contains a combination of both high priority partition data bytes and low priority partition information bytes. In k of those packets the high priority partition data bytes are all high priority partition information bytes and in n-k of those packets all the high priority partition data bytes are parity bytes produced by the FEC coding. More specifically, for each high priority partition information byte position within the n packets, the forward error/erasure correction code is applied using one high priority partition information byte from the same byte position in each of those k packets to determine n-k parity bytes, which are arranged, one byte per packet, in the n-k packets containing high priority partition parity bytes. If up to n-k packets are lost in transmission over the packet network to the receiver, then the high priority partition information bytes in such lost packets can be recovered to applying FEC decoding to the high partition bytes in the received packets. The most visually significant information is thus protected against packet loss over the network.

Abstract: Mail can be sorted automatically to point of delivery level by deriving from the address including postal code on a piece of mail a suffix which together with the postal code forms routing data which uniquely identifies the final delivery address.      This is achieved automatically at the Post office sorting facility by means of an optical character reader which reads the addresses on mail items and a computer arranged to generate a suffix based on the address read. The routing data is printed as a bar code on the mail item and this allows the complete sortation to be effected automatically. Also contemplated is a progressive encoding system which can be applied as bar codes by customers as desired to mail pieces. The basic data is the routing data set to which can be added a shipment number which allows automatic revenue accounting control and a piece number which allows automatic track and trace. Finally, the customer may also progressively encode return mail envelopes with the shipment number followed by a product code and a user defined field which permits automatic specialized handling of the return mail item.

Abstract: A film fill-pack has a plurality of fill-sheets with an ordered array of ridges and grooves. generally extending above a planar surface on both the obverse and reverse surfaces of a fill-sheet, which fill-sheets at an assembled state provide the ridges and grooves of facing obverse and reverse surfaces of adjacent fill-sheets in an arrangement providing a plurality of channels between adjacent fill-sheets for gas flow therethrough and where the ordered arrangement of ridges and grooves induces spiraling of the gas flow through the channels for promotion of improved heat transfer; and, where the fill-sheets further include a spacing arrangement providing a compact nesting of adjacent sheets with minimal sheet-to-sheet displacement at least at two of the edges for compact handling, transfer and storage with a self spacing of adjacent fill-sheets at assembly of the film fill-pack.  Fill-packs generally utilize retention louvers at a gas-inlet site to maintain coolant fluid within the fill-pack structure, which disclosed louvers have specific relationships to their angularity, height and length to minimize their volume while maintaining their operational characteristics, and mist eliminators at air discharge locations are operable to minimize gas-entrained coolant discharge to retain the fluid within the cooling apparatus with the control of the angles of mist-eliminator grooves, the structural cross-section of the grooves and the use of microgrooves.

Abstract: A pneumatic valve (50) and regulator (1), and more particularly to a pneumatic valve and regulator used in a compressed gas powered gun system which is designed to project a fragile liquid-containing spherical unit which bursts upon impact with the intended target. The regulator (1) possesses a pressure balancing device (17, 18, 19), a temperature compensating device, and relief valve features. The temperature compensator (17) of the temperature compensating device is made of a synthetic compound material which expands and contracts at a rate that equals but is inverse to the rate of change caused by changes in the modulus of elasticity of a helical compression spring (21) caused by a temperature differential. The valve possesses a seal (62) made of pressure-activated material, the outer diameter of the seal is mechanically captured, the inner diameter of the seal is not constrained from moving into the cavity. The application of pressure initiates the flow characteristics of the seal at the interface of the inner diameter of the seal and the outer diameter of the poppet. This sealing technique has inherent lubricity, is self-healing, is non-temperature sensitive, and is compatible with all noble gases used.

Abstract: A vestigial sideband/quadrature amplitude modulation (VSB/QAM) receiver, which receives both a VSB signal and a QAM signal, and a method thereof are provided. The receiver has an analog-digital converter for A/D converting according to a frequency higher than the symbol frequency of a received signal; an interpolator for calculating a signal value on the original symbol location after a signal from the A/D converter is applied; a carrier wave restoration unit for restoring a carrier wave by selectively using an automatic frequency control (AFC) and a digital frequency phase locked loop (DFPLL) according to a VSB/QAM mode after a signal from the interpolator is applied; a timing processor for receiving a signal from the carrier wave restoration unit, detecting a timing error after making a symbol input time different according to a VSB/QAM mode, controlling the interpolator based on the detected timing error, and generating a restored clock; and a VSB sorter for extracting a VSB receiving symbol. Therefore, according to the receiver, by restoring a carrier wave with a restored symbol clock after restoring symbol timing in the front part of the carrier wave restoration unit, a frequency having low symbol rate can be used, correction of the distortions in a carrier wave can be quickly done, and requirement for additional hardware for receiving a VSB signal can be very smaller.
