Title: Network router
Inventor: JENNINGS KEVIN
IPC: H04L45/16
Filed: 2000-05-10
Abstract: A network router has a distributed processing scheme for multicast packets. The router has a look-up and forwarding engine operative in response to the reception of an internet protocol multicast packet to direct the packet to a multiplicity of transmit ports which may or may not be connected to the source network segment from which the multicast packet was received by the router. Each transmit port is associated with a predetermined default network segment and the engine directs the packet to the ports (e.g. across the router's backplane) with an identification of the source network segment and control flags which enable processing means associated with the ports to determine by comparison of the respective network segment and the source network segment whether the packet is bridged from the respective port or routed, with relevant modification of the packet, from that port. The control flags comprises a first flag which can be set to allow the relevant modification and a second flag which can be set to allow the comparison between the source segment and the predetermined default segment.

Title: Locating mobile telephones
Inventor: MOCKFORD STEPHEN
IPC: G01S5/10
Filed: 2000-05-16
Abstract: A method of locating a mobile telephone handset comprises the steps of (i) calculating a predicted signal property such as signal strength or observed time difference for a plurality of possible locations for the handset, (ii) comparing the predicted signal property with a measured signal property and (iii) deriving from the comparison a probability that the handset is at one or more of the locations. The method can be refined by combining the thus derived probability map with a probability map based on geographical information or historical data or both. Thus a peak probability which moves along a path parallel to a road indicates the handset is on that road. Several probability maps for example based on time differences, signal strength, geographical data and historical data can be combined simultaneously or sequentially to identify a peak probability.

Title: A processor for executing compressed instructions and method of compressing instructions
Inventor: TOPHAM NIGEL PETER
IPC: G06F9/38
Filed: 2000-05-25
Abstract: Compressed instructions of a program are stored in a program memory 12. In a processor which executes the instructions, a program counter 50 identifies a position in the program memory 12. A cache loading unit 42 includes a decompression section 44 and performs a cache-loading operation, in which one or more compressed instructions are read from the identified position in the program memory 14 and are stored in one of a plurality of blocks of an instruction cache 40. An instruction fetching unit 46 fetches an instruction to be executed from a position in the instruction cache identified by a cache pointer 52. When a cache miss occurs, the cache loading unit performs a cache loading operation. The program counter 50 and cache pointer 52 are updated by an updating unit 48 in response to the fetching of instructions. A method of compressing instructions to be executed by such a processor is also disclosed, in which a sequence of original instructions is convened into a corresponding sequence of compressed-form instructions. The original instructions are assigned imaginary addresses at which the instructions are considered to exist when held in the instruction cache of the processor. The compressed-form instructions are stored in the program memory, together with the imaginary address information so that when the compressed-form instructions are decompressed and loaded by the processor into the instruction cache, the processor can assign the specified imaginary addresses to the decompressed instructions.

Filed: 1999-03-11
Abstract: Apparatus for the identification of articles (5) endowed with means for changing the polarisation properties of the radiation, comprising a source (1) of non-randomly polarised microwave radiation, and means (3) for detecting the change in polarisation properties of the radiation. The microwave radiation may have a first plane of polarisation and, in use, the means for changing the plane of polarisation properties of radiation may change the first plane of polarisation to a second plane of polarisation. The means (3) for detecting the change in polarisation properties of radiation may comprise a receiving antenna (4c) connected to suitable microwave detecting means (3), where the receiving antenna (4c) is arranged to favour reception of radiation having the second plane of polarisation. For example, the transmitting (4b) and receiving (4c) antennas may be waveguide antennas. The means for changing the polarisarion of radiation may comprise a feature having an edge oriented at a non-zero angle to a direction parallel with, or orthogonal to, the first plane of polarisation. Typically, the feature may be a linear metallic strip, or may be a feature having a crossed dipole antenna structure. The apparatus may also comprise means for determining the orientation of the feature or features. The polarisation changing means may also comprise covert means for preventing the changing of the polarisation properties by the polarisation changing means in one or more selected location, wherein the arrangement of the one or more selected location provides an identification code.

The encoder, the serializer, the sequence generator circuit, and the multiplexer may be fabricated in a single integrated circuit chip. The parallel test data may be parallel pseudo-random binary sequence data that repeats every 2<SP>23</SP>-1 clock cycles when in serial form, and may be generated by twenty three clocked D-type flip flops coupled together. The parallel digital data may include data to generate colors in a visual image, and the encoded and serial digital data may be received, deserialized, decoded, and displayed in a display unit. The transmission medium may be copper cables, optical fibers, or fiber optic cables. The encoded and serial digital data or the serial test data may be transmitted as a differential signal over the transmission medium.
