Title: Head bathing system
Inventor: SIMON KEITH M
IPC: A45D19/14
Filed: 2000-01-21
Granted: 2007-04-03
Abstract: A head bathing system for haircare. The system is composed of an outer cap having a head-receiving aperture, an inner, absorbent liquid-holding layer, and a flexible gathering for the cap at the aperture. The liquid-holding layer is impregnated with a cleansing solution. To clean a person's hair, the system is applied to the person's head, which is massaged through the cap to cause the cleansing solution to wet the person's hair. After sufficient cleaning, the system is removed from the person's head. Because of the nature of the liquid-holding layer, it reabsorbs much of the cleansing solution before the system is removed from the person's head.
Patent CA-2298542-C (CA)
Inventor: NICHOLS DAVID EDWARD
IPC: G01V1/28
Filed: 1998-08-12
Granted: 2003-10-07
Abstract: The invention relates to a method of processing seismic data that is less sensitive to the consequences of multiple propagation paths. There may be three paths (16, 18, 20) between a seismic source (S) and an image point (I). Signals in paths (16 and 20) are refracted by salt bodies. If there were also three paths between a seismic receiver and the image point (I), there would be 9 possible permutations of outward and return signal paths for image point (I) and to account for all of these paths would be prohibitive. According to the present invention, the raypath resulting from the shortest outward and return paths is selected for subsequent processing (such as pre-stack depth migration etc.). The traveltime curves associated with the raypaths having shortest ray length are piecewise continuous and more likely to be associated with more of the energy than either the first arrival or the maximum amplitude arrival thus assisting in effective analysis of the seismic data.

Title: Method and apparatus for performing service level analysis of communications network performance metrics
Inventor: NISBET THOMAS R
IPC: H04L12/56
Filed: 1998-11-06
Granted: 2002-05-21
Abstract: A data transmission system includes probes (probe A, probe B) connected between end user sites (site A, site B) and a data switching network (12).  Each probe is connected to the switching network (12) via an access channel (20, 21, 26 or 27) wherein transmission circuits establish paths between the sites through the access channel (20, 21, 26 or 27) and switching network (12). The probes capture and retransmit data traveling between the sites over respective transmission circuits, and can thereby insert service level anaylsis (SLA) messages into data traffic in order to actively communicate network performance information to other probes. For each transmission circuit, the probes periodically collect measurements related to one or more network performance metrics, including round-trip delay (RTD), data delivery ratio (DDR) and network availability. During each SLA measurement cycle, a sequence of SLA messages is exchanged over each transmission circuit, which messages contain data used to determine RTD and DDR.
Patent CA-2308902-C (CA)

IPC: H04B7/005

Granted: 2003-12-02
Abstract: Multiple microcell base stations are located within a macrocell having a single macrocell base station in an hierarchical architecture, and microcell users (µ-users) and macrocell users (M-users) communicate respectively with the µ-base and the M-base using the same frequency band, by appropriately (a) selecting the ratio of the radius r of each µ cell and the average distance d from the M-base (r and d are measured by the "radio distance", which includes the effects of shadowing), and (b) controlling the power level with which uplink (mobile to base) and downlink (base to mobile) messages are communicated. Typically, µ-cell size and location are chosen such that d/r > 10. With respect to uplink communications, the transmit powers of the µ -users in a µ-cell are controlled so that the total received power at the nearest M-base is equivalent to the received power from C M-users, where C  is usually set to unity. As a result, the M-cell basically loses C users worth of capacity, but the total number of users is increased by virtue of the additional µ-users. With respect to downlink communications, as long as the microbase and the macrobase are coordinated systems, the µ-base transmit power is controlled so that at the point of handoff between a µ-base and M-base, the received power at a user from the two bases is equivalent, and the received power at the bases from this user is also equivalent. With this arrangement, the µ-base transmit power is increased as r grows and d decreases in order for this balance to occur. Where the M-base and µ-base have no knowledge of each other and handoffs are not allowed between the two base types, a family of I/Q short codes which are quasi-orthogonal to the existing short (pilot) codes are generated, and these codes are used to distinguish between the M-base and µ-base signals.

Title: Method and apparatus for creating and sending structured voicemail messages
Inventor: MATAGA PETER ANDREW
IPC: H04M3/533
Filed: 2000-05-16
Granted: 2003-06-10
Abstract: A sender (101) creates a voicemail message that includes a plurality of messaging elements that include embedded instructions that define a structure of the message. Other messaging elements may include textual fragments, audio fragments that refer to audio data files that are associated with the message, and/or references to textual fragments and/or audio fragments that are stored at specified locations. The instructions may define a hierarchical menu structure which, when the message is presented to the recipient (106) by a messaging system (104), offers the recipient different navigational choices from which the recipient may select and thus effect the information content of what is presented. The structured message is sent by the sender to the recipient at an address on a messaging system that stores the message and is capable of interpreting and assembling the messaging elements in accordance with the embedded instruction and playing-out the message to the recipient when the recipient accesses the system and retrieves the message from storage. The structured message may also include links to a specific destination, to which the messaging system establishes a connection if the link is selected by the recipient during play-out of the message. Further, the messaging system can gather information from the recipient during play-out and forward that information to a specified destination, which may respond with another structured message. In the described embodiment, a phone markup language is used to define the structure and the inherent embedded instructions associated with the structure of the message.

Title: Establishing bi-directional communication sessions across a communications network
Inventor: GIBSON MARK ROBERT
IPC: H04L12/56
Filed: 2000-09-29
Granted: 2010-05-25
Abstract: On receipt of a request for a communication session over a communications network, such as an Internet Protocol communications network, a path for the session is established. In a preferred example the communications network is an MPLS network and the method uses a modified version of the SIP messaging protocol. Bandwidth along a chosen path is reserved and a messaging protocol such as CRLDP used to establish this reserved path for the communication session. Internet protocol and MPLS communications networks typically only support uni-directional flows. Several methods for establishing bidirectional communication sessions over internet protocol communications networks that use MPLS connections are described. This is particularly useful for telephony applications using internet protocol communications networks. In a preferred example, the established connection provides a guaranteed level of quality of service.

Abstract: For one embodiment, a Random Access Channel (RACH) preamble modulation method and apparatus are disclosed in which the real (I) and imaginary (Q) components of a complex RACH preamble (b(k)) are filtered in corresponding pulse shaping filters (206, 208). Consequently, the phase transitions in the resulting signal are limited at all chip positions, and the resulting quadriphase codes produce transmitted signals with lower Peak-to-Average Power Ratios (PAPRs) than those that result using conventional Hybrid Phase-Shift Keying (HPSK) modulation schemes. On the other side, the resulting quadriphase synchronization code retains the same aperiodic autocorrelation magnitude as the original binary code (a(k)), optimized to produce the minimum probability of incorrect synchronization.
