Patent CA-2426813-A1 (CA)
Inventor: THOMAS STEPHEN A
IPC: H04B10/272
Filed: 2001-10-26
Abstract: A protocol for an optical network can control the time at which subscriber optical interfaces of an optical network are permitted to transmit data to a  transceiver node. The protocol can prevent collisions of upstream transmissions between the subscriber optical interfaces of a particular subscriber group. With the protocol, a transceiver node close to the subscriber can allocate additional or reduced upstream bandwidth based upon the demand of one or more subscribers. That is, a transceiver node close to a subscriber can monitor (or police) and adjust a subscriber's upstream bandwidth on a subscription basis or on an as-needed basis. The protocol can  account for aggregates of packets rather than individual packets. By performing calculation on aggregates of packets, the algorithm can execute less frequently which, in turn, permits its implementation in lower performance and lower cost devices, sich as software executing in a general purpose microprocessor.

Patent CA-2434022-A1 (CA)
Title: Sealing structure in direct acting type auto-by starter
Inventor: MASUNAGA AKINOBU
IPC: F16J15/52
Filed: 2003-06-30
Abstract: To prevent the entry of ambient air and liquid such as rainwater into a direct acting type auto-by starter and thereby prevent the formation of rust in the auto-by starter, by adjusting pressure fluctuations in the auto-by starter caused by the operation of a starting valve for opening and closing a starting intake passage. A starting valve 2 is lifted by upwardly operating a manual lever 7, thereby opening a starting intake passage 1c to start an internal combustion engine. A pressure in a sliding space 2f for the starting valve 2 is increased by the lift of the starting valve 2, so that the gas in the sliding space 2f flows out of the sliding space 2f. The flow of the gas is absorbed by an increase in volume inside a bellows boot 5 mounted on an upper portion 2b of the starting valve 2. When the starting valve 2 is lowered by the operation of a spring member 6, the pressure in the sliding space 2f is reduced to allow the gas flow from the bellows boot 5 into the sliding space 2f. This gas flow is absorbed by a decrease in volume inside the bellows boot 5, thereby preventing the entry of ambient air and water into the auto-by starter 10.

Filed: 2003-10-03
Abstract: Methods and apparatus are provided for communicating an audio stream.    A perceptual mask is estimated for an audio stream, based on the perceptual threshold of the human auditory system. A hidden sub-channel is dynamically allocated substantially below the estimated perceptual mask based on the characteristics of the audio stream, in which additional payload is transmitted.   The additional payload can be related to components of the audio stream that would not otherwise be transmitted in a narrowband signal, or to concurrent services that can be accessed while the audio stream is being transmitted. A suitable receiver can recover the additional payload, whereas the audio stream will be virtually unaffected from a human auditory standpoint when received by a traditional receiver. A coding scheme is also provided in which a portion of a codec is used to code an upper-band portion of an audio stream, while the narrowband portion is left uncoiled.

Title: Method and system for handling a network-identified emergency session
Inventor: KAUPPINEN RISTO
IPC: H04W76/50
Filed: 2001-04-27
Abstract: The invention relates to a method and system for establishing an emergency session in a communication system which includes at least one user equipment and one or more network entities involved in establishing an emergency session. When the user equipment initiates a session by sending a message to a network entity indicating an identifier, e.g. the call number or logical name of a called entity, one of said network entities analyses the received identifier. When detecting that the session to be initiated is an emergency session, an information is returned to the user equipment for informing the latter that the initiated session is an emergency session. The user equipment thereupon initiates the execution of an emergency session. Thus, even when the user equipment is unable to detect, by itself, that the intended session is an emergency session, the network will inform the user equipment on the emergency session for ensuring appropriate handling thereof.
