Patent CA-2219093-A1 (CA)
Title: Voice mail system
Inventor: PORTER LAWRENCE LEON
IPC: H04M7/00
Filed: 1995-08-24
Abstract: Using the Internet World Wide Web (WWW) network (320), a WWW client (310) can communicate  with a WWW Server (330) to request access to a user's voice mail. In order to satisfy this request, the user enters his voice mail mailbox number, and activates an appropriate hyperlink. The WWW Server then launches an application, MSG Client (350), which in turn communicates with an application, MSG Server (370), that runs in conjunction with the voice mail system (380, 385, 390). In response to an initial message from the MSG Client, the MSG Server returns information about all voice mail messages within the specified mailbox, which are displayed at the WWW Client. This display includes a hyperlink to each message in the mailbox. Thus a user can select a message from within the mailbox by activating this hyperlink, which prompts the WWW Server to again launch MSG Client. This in turn sends a second message to MSG Server, which responds by returning the actual audio data for the selected message to the MSG Client, which is forwarded onto the WWW Client via the WWW Server. The WWW Client then plays out the audio data, allowing the user to hear his or her selected voice mail message.

Patent CA-2238449-A1 (CA)
Title: Equalisation, pulse shaping and regeneration of optical signals
Inventor: ROBERTS KIM BYRON
IPC: G02F2/02
Filed: 1998-05-22
Abstract: Data carrying optical signals are subjected to equalisation or pulse shaping of the optical signal waveform. A plurality of optical tap signals derived from the optical signal are used to control a modulator operating on an input signal to provide an output signal having the desired waveform. A Mach-Zehnder interferometer having semiconductor optical amplifiers in each arm provides modulation by the effect of cross modulation induced by propagating the respective tap signals through a selected one of the semiconductor optical amplifiers. Various forms of transversal filter are provided by selecting the number of optical taps, assigning positive or negative weights and appropriate delays. The effects of dispersion in optical signals can be mitigated by utilising optical taps with negative weights to subtract tail portions from the leading and trailing edges of a signal pulse. the invention has application to systems with high bit rates where equalisation or pulse shaping in the electrical domain is difficult to implement.

Patent CA-2246770-A1 (CA)
Inventor: BEPLATE DOUGLAS K
IPC: A61M16/20
Filed: 1996-12-31
Abstract: The dual-filtered rotary isolation valve for resuscitation isolates, by filtering. a patient from a provider of care when such provider of care attempts to resuscitate such patient by forcing the provider's breath into the patient's lungs. No prior art device provides filters for all pathways that may be taken by breath exhaled by the care provider and the patient while having a path that would enable the often weak incipient breath of a patient to escape from the patient's lungs to the atmosphere even if the care provider is exhaling at the same time. Breath exhaled by a care provider passes through an upper filter segment (35), a space (388) to retain moisture, a lower filter segment (36), and a check valve (28). The check valve (28) prevents air exhaled by the patient from reaching the care provider, causing the patient's breath to pass through an exhalation filter (23) before reaching the atmosphere.

Title: Toe and metatarsal protectors for safety footwear
Inventor: KRAJCIR DEZI A
IPC: G06F12/08
Filed: 1998-09-15
Abstract: A toe and/or metatarsal protector for safety footwear are molded from plastics material integrally or as separate parts. Each protector part comprises a generally U-shape body provided at the centre of its upper surface with a force receiving part overlying the respective central part with a space between them. Each force receiving part may be integral with or separate from its respective protector body part. Crushing and impact forces applied to the force receiving part flatten it and press it toward the central part with conversion of such forces to longitudinal forces distributed along its spaced junctions with the body part and compression forces in the sides of the U-shape body. The force receiving plate when separate may comprise a thin molded sheet of plastics material or metal. Each metatarsal protector may be divided along its length by transverse slots to increase its longitudinal flexibility so as to accommodate walking.
