Abstract: Various telephone features are implemented for use during a conference call. In order to implement features, an identity of each party to the conference call is stored. An identity of a second party to the conference call is displayed on a display of a first telephone used by a first party to the conference call. If the display on the first telephone is large enough, all the parties in the conference can be displayed. Alternatively, the first telephone displays only one party to the conference at a time. A scroll feature is used to scroll through all the parties to the conference. A private consultation may be conducted between the first party and the second party. In response to the first party depressing a consultation feature button on the first telephone, the first party and the second party are temporarily disconnected from the conference call, and are temporarily connected to each other in a point-to-point call. In response to the first party again depressing the consultation feature button on the first telephone, the first party and the second party are disconnected from the point-to-point call and reconnected to the conference call.

Patent CA-2268246-A1 (CA)
Inventor: BOOT ADRIAAN JOHAN
IPC: H04B10/572
Filed: 1997-11-21
Abstract: Optical stabilisation system having a signal source (1) connected to a transmission line (2) and a noise source (3). The signal source (1) comprises a laser having a number of laser modes within a first wavelength band for generating an optical transmission signal (S). The noise source generates a narrow-band noise signal which is inserted into the transmission line via coupling means (5) and is injected into the laser of the signal source (1). The noise signal forces the laser to operate in a laser mode within the noise band. Via a power distributor (11), a portion of the noise signal can also be injected into a laser of a further signal source (9) for stabilisation in a laser mode within the same noise band. Any signals outside the noise band are removed from the transmission signal by a narrow-band filter (8). The stabilisation system is applied in passive optical networks for groupwise wavelength assignment to network terminals.

Filed: 1998-09-17
Abstract: An ATM repeater realizing high speed hop-by-hop forwarding without employing any high speed processor comprises a processor (11) and a forwarding destination retrieving circuit (12) constituted of hardware. The destination retrieving circuit (12) extracts header information from the received IP packet data and searches an associative memory (21) using the header information as a key. When the corresponding forwarding information cannot be acquired by searching the associative memory (21), a pointer table (22) for HASH search is searched by using an HASH function. When forwarding information is acquired from a forwarding table (23) as a result of the search, hop-by-hop forwarding of the IP packet data is performed based on the forwarding information.

Patent CA-2278997-A1 (CA)
Inventor: SCOTT ANTHONY J
IPC: B29C33/04
Filed: 1999-07-23
Abstract: Improved blow-molding prototype molding system, method and apparatus wherein a plastic container is first designed using computer-aided design (CAD) software to produce a geometric computer software model of a hollow plastic container of desired contour. This model is then used to generate a geometric computer software model of a corresponding mold cavity. This data file in turn provides the control signal for a cutting tool of a CNC three axis mold machining tool operating on a starting blank for each mold half of metal material having predetermined and constant length, width and thickness outside dimensions. A mold cavity is thereby automatically machined in a front face of this blank that constitutes one of the two major and parallel face planes of the mold half block. The other half of the mold cavity is similarly formed in the front face of a second mold half block that cooperates with the first mold block to form the two mold halves of a complete blow mold. The back faces of each of the mold halves as well as the top, bottom and two opposite sides remain as initially provided in the starting blank. Standardized major mold nest fixture components cooperate in assembly to support, locate, orient and cool the associated prototype mold halves. The structure of each mold half is thus reduced to its simplest form, and instead all the functions of water cooling, mold orientation, alignment, structural support, reinforcement against mold closing and blowing stresses, and adjustment for aligning the two mating mold halves in operation, is provided for in the standardized and re-usable major mold assembly nest parts. Thus, mold construction time is significantly reduced as well as mold machine set-up and take-down time.

Patent CA-2288920-A1 (CA)
Title: Optical switch mechanism
Inventor: MACDONALD ROBERT I
IPC: G02B6/35
Filed: 1999-11-04
Abstract: An optical switch mechanism for reflecting an input light beam from an input port to a reflection output port in a first state and for transmitting an input light beam to a transmission output port in a second state is disclosed. The switch mechanism comprises a block made of a light transmissive substrate. The block contains a cavity, which is divided by a light transmissive diaphragm into a reflective portion and a transmissive portion. At the input port a light beam is coupled into the block such that the light beam encounters a reflective surface at an angle greater than a critical angle determined by the refractive indices of the substrate and a reflective fluid retained in the reflective portion of the cavity. When the reflective fluid is in contact with the reflective surface the light beam is totally reflected to a reflection output port. Changing hydrostatic pressure moves the transmissive diaphragm into a position where it is in a touching relationship with the reflective surface and the light beam is then transmitted to a transmission output port. The switch mechanism is simple, reliable, fast and easy to manufacture.
