Patent CA-2272576-A1 (CA)
Inventor: BREMER GORDON
IPC: H04J1/00
Filed: 1997-12-04
Abstract: A method and apparatus are provided for communicating data (25) across a communication link (26), in a manner that senses and dynamically adapts to the simultaneous transmission of voice information (30, 32) across the local loop. In accordance with one aspect of the invention, a method is provided for dynamically communicating data (25) over a local loop using a modem (20) comprising the steps of transmitting data in a full-band transmission state, sensing a band-limiting condition, and adjusting the transmission of data from the full-band transmission state to a band-limited transmission state, in response to the sensing step. A significant aspect of the present invention is the dynamic allocation of the data transmission bandwidth, whereby the invention senses a condition indicative of whether voice information (30, 32) is being communicated. If so, then the system shifts and/or narrows the data transmission bandwidth to allow for voice communications without interference from or with the data transmission.

Patent CA-2277826-A1 (CA)
Title: A computerized device for improving motor control in an individual by sensory training
Inventor: MERZENICH MICHAEL M
IPC: A61B5/103
Filed: 1998-11-09
Abstract: A method and apparatus for implementing a training regimen which addresses motor control problems accompanied by sensory degradation. Accordingly, the training regimen is applicable to motor control disorders associated with a variety of different causes, including traumatic injury, disease, aging and gradual "occupational" type injury. For example, in an individual suffering from repetitive strain injury (RSI), the disabling motor control problems are often accompanied by sensory problems. These sensory problems appear to be caused over time by harmful attended rapid repetitive movements resulting in undesirable changes in the somatosensory, proprioceptive and/or kinesthetic ability of the affected regions of the individual. The present invention hypothesizes that repetitive delivery of simultaneous or nearly simultaneous afferent sensory inputs, under attended conditions of high cognitive drive, results in a learning-induced integration of the representation of the individuality of otherwise differentiable parts of the subjects thereby degrading the sensory feedback loop necessary for normal motor control. What started out as a degradation of the sensory feedback capability, essential for proper motor control, eventually manifests over time as a motor control problem. Thus, motor control problems which are accompanied by sensory degradation can be alleviated by a regimen of remedial re-differentiating sensory training of the affected regions of the individual. Accordingly, the training regimen differentially stimulates two locations within the afflicted portion of the individual. Feedback from the individual indicates the degree of difficulty the individual has in sensing differentially between the two locations. The stimulation is then adapted to the individual based on the feedback. Adaptation includes increasing the distance between the two locations and/or changing the spectral or temporal characteristics of the stimuli.

Patent CA-2280822-A1 (CA)
Inventor: ENNS FREDERICK
IPC: H04L29/08
Filed: 1998-02-06
Abstract: A medium access controller for a client-server network that assigns protocol-dependent upstream channels according to client status and type-of-service requests. One group of upstream channels utilizes a contention-only protocol, a second group utilizes a limited type polling protocol, and a third group utilizes an exhaustive polling protocol. Further, when the client is non-responding, e.g., turned off, the controller assigns a first channel group using a contention-only protocol. For client communications requiring low latency for optimized performance, the controller assigns a second group of available upstream channels, and for communications requiring maximum throughput at the expense of longer latency times for optimized performance, the controller assigns yet a third group of available upstream channels. After initiating a data transmission, the controller may further dynamically assign channels based on detected changes in the transmissions. Thus, rules based on client activity level are implemented to determine when the client is to switch between channel groups. Essentially, the controller effects switching of the user's upstream channels dynamically and intelligently on a packet-by-packet basis.

Title: Pressure compensating valve
Inventor: BERNDTSSON GORAN BERTIL CLAES
IPC: A62B18/10
Filed: 1998-02-18
Abstract: This invention relates to a pressure compensating valve and more particularly, but not exclusively, to a balanced pressure compensating valve, or regulator. The valve includes a chamber (6) for containing fluid, defined by a flexible barrier (2) trapped between first (3) and second (4) surfaces. A fluid inlet provides fluid to the interior of the chamber. A fluid outlet selectively allows fluid to pass out of the chamber.      Movement of the first (3) and second (4) surfaces relative to each other causes change in contact between the flexible barrier and the first and second surfaces to selectively open the fluid outlet, in a first position, and occlude it between the flexible barrier and one of the surfaces, in a second position.

Title: Child resistant lighter
Inventor: AMOROS NOLLAS ENRIQUE
IPC: F23Q2/28
Filed: 1998-08-31
Abstract: A lighter (10) of the disposable type, ignition of which requires depression of an actuator (14) that is resistant to the manipulations of unintended users. The lighter (10) is normally maintained in a position that prevents depression of the actuator through the incorporation of a mechanism that increases the difficulty of operation. The actuation inhibiting mechanism (22, 26, 42, 44) requires a downward displacement and a tilted displacement in order to allow full depression of the actuator (14) and activation of an ignition mechanism (20, 20a, 20b). Preferably, at least one biasing element (28, 38, 80) is provided so that when the actuator is displaced through the application of force by a user, it returns to the initial blocking position when the force is removed.
