Title: Communication network including a virtual terminal
Inventor: FREEMAN DAVID
IPC: H04L29/06
Filed: 2000-02-15
Abstract: A communication network includes, for example, a receiving station 1 communicating with a base station 2-6. The base station includes a virtual terminal 7 which includes a processor and store maintaining replica data of the receiving station 1 providing the functions and capabilities needed for operation of the receiving station. The virtual terminal 7 communicates with the receiving station 1 using the capabilities of the receiving station. The virtual terminal may interpret and transform incoming data into a form that is acceptable to the receiving station. The arrangement may find application in allowing a second generation mobile access to a third generation system. Alternatively, the virtual terminal receives and stores services or applications while the receiving station is unavailable and transmits the received signals at a later time to the receiving station. In an alternative embodiment, a virtual terminal is provided in each network so that information pertinent to a receiving station is transferred from a virtual terminal in one network to a virtual terminal in a roamed to network.

Title: Reverse rotation wrap flank separation of a scroll compressor
Inventor: HUGERROTH JASON J
IPC: F04C29/00
Filed: 2000-04-14
Abstract: <PC>A scroll compressor is provided with structure that causes the flanks of the wraps 23,25 to move out of engagement when reverse rotation occurs. An eccentric pin 30 and slider block 28 are constructed such that when forward rotation is occurring, flat surfaces 42,40 on the pin 30 and slider block 28 are brought into contact to drive the slider block 28 and hold the wraps 23,25 in engagement. However, when reverse rotation occurs, the flat surfaces 40,42 move out of engagement. The slider block 28 has a pivot point 36 which moves into contact with a groove 38 in the eccentric pin 30. The slider block 28 pivots relative to the eccentric pin 30, and the wraps 23,25 of the scroll members are brought out of engagement, so that compression chambers are not defined when reverse rotation occurs. Another embodiment involves a slider block groove (68, Fig.4) which moves into, and pivots against, a a separate pin (70), which is formed as part of the drive shaft (71), upon reverse operation of the compressor.

Title: Spacer for insulated windows having a lengthened thermal path
Inventor: PETERSON WALLACE HARVEY
IPC: E06B3/663
Filed: 2000-07-21
Abstract: A spacer frame bar (18) for insulated windows or other insulated glass panels (10) comprises a tubular spacer member (44,46) having first and second side webs (34,36) for engaging the spaced apart glass panes, and upper and lower webs (30,32) spanning between the side webs. The upper web (30) is provided with a series of vertical corrugations (70), which serve to increase the length of the thermal conductive path across the upper web. The corrugations are also arranged so that only the upper edges thereof are exposed to sunlight passing through the window, thereby minimizing thermal gain due to absorption of solar radiation. Staggered rows of slits (80) may be formed in the channels of the corrugations (70) so as to further increase the length of the conductive path. The channels may also be filled with an insulating material, such as a resilient foam material. The invention also provides a two-piece construction in which the top web clips onto the upper edges of the side webs.

Title: Mapping between TDM channels and packets
Inventor: FLOYD GEOFFREY EDWARD
IPC: H04Q11/04
Filed: 2001-08-11
Abstract: A method of mapping between contexts of a packet network and TDM channels and streams. The method comprises constructing a lookup table defining the sequence in which data is to be mapped between contexts and TDM channels and streams, and including for each row of the table a flag which indicates whether or not that entry is the first entry in the table for the corresponding context. As the TDM receive or transmit entity cycles through the lookup table, use is made of the flags to synchronise the start of each packet with the first entry of a TDM frame for each context.

Title: A method and apparatus for indexing and searching data
Inventor: SPACEY SIMON ALAN
IPC: G06F17/30
Filed: 2001-09-10
Abstract: This invention presents a method or system for rapidly indexing and searching data. The method can be used to quickly return all locations with a data set where a group of bytes is to be found. The invention works by creating a special index on the data structure. The index can be synchronised with the data source as inserts and deletions are performed so that there is no need to rebuild the index. The method according to the invention performs with a similar speed to a traditional optimised search tree but has at most the same number of elements as the data it indexes making the method of the invention ideal for indexing and searching large quantities of dynamic or static data. The index comprises a number of lists, each list holding references to the positions where a particular symbol is found in the data. The number of lists may be static or dynamic.

Inventor: CREWS JAMES B
IPC: C09K8/62
Filed: 2001-10-30
Abstract: A method of breaking a viscoelastic surfactant (VES) fracturing fluid involves introducing a biochemical agent in the form of bacteria, fungi, enzymes or combinations thereof. Said agent may work on the VES directly by dissaggregating or rearranging the micelle structure of the VES or may work on another component of the fluid, such as an alcohol or an oil, to produce a byproduct which in turns breaks the fluid. The VES can be erucyl bis-(2-hydroxyethyl) methyl ammonium chloride and various types of suitable bacteria, fungi and enzymes are disclosed. The action of the biochemical agent may be enhanced by manipulation of the temperature, pressure and pH.
