Abstract: The invention relates to a housing having a holding device arranged on a base plate and comprising a circular arrangement of radially resilient clamping limbs having radially outward clamping surfaces for engagement in a central opening of at least one disc-shaped information carrier, for example a CD, rigid supporting limbs having radially outward supporting surfaces being interposed between the clamping limbs and the diameter of the circular arrangement of supporting surfaces being slightly smaller than the diameter of the central opening of the information carrier. It is an object of the invention to provide a housing of the afore-mentioned type, which allows the clamping force on the information disc to be increased without the immunity to severe impact loads being affected. To this end, the rigid supporting limbs have radially resilient clamping noses having radially outward clamping surfaces for engagement in the central opening of the disc-shaped information carrier.
Patent CA-2296941-A1 (CA)
Inventor: DEVITO NICHOLAS MICHAEL
IPC: H04M3/537
Filed: 2000-01-21
Abstract: A new intelligent network feature that provides switch based voice mail systems with the same dial up toll saver indications as the better customer premises answering machine equipment. If there are no messages, the tollsaver feature will have the voice mail system pick up after the normal number of rings, typically four or five. If there are messages, the voice mail system will pick up after fewer rings, typically two or three. Thus, if the subscriber calls in remotely he or she can and should hang up after three rings to avoid an unnecessary toll charge for an empty voice mail box. However, if the subscriber calls in and waits for three rings and hears the system start to pick up, then the subscriber knows that the call will be worth the connect charge because there is a message to playback. Thus, by this method and apparatus switch based voice mail has the same tollsaver feature as home answering machines.

IPC: G06F9/445
Filed: 2000-03-08
Abstract: A method, system, and computer program product for transparently loading resources (such as stored bitmaps, images, fonts, and sound files) from read-only memory ("ROM") for an application program executing on a Java virtual machine ("JVM"). Typically, the invention will be used on an embedded computing device which has no disk storage and no file system software. A novel class loader is described, which loads resources from ROM  and returns an input stream object as is expected by the existing application program.  Therefore, when using the present invention, no change is required to existing application code to use resources stored in ROM. (In addition, no change to existing applications is required in order to invoke the code of the present invention.) The invention may be used with programs written in the Java programming language, or with programs written in other languages that execute on a JVM.

Patent CA-2301199-A1 (CA)
Inventor: TAVTIGIAN SEAN V
IPC: C12Q1/68
Filed: 1998-08-26
Abstract: A specific region of chromosome 10 (10q23.3) has been implicated by series of studies to contain a tumor suppressor gene involved in gliomas, as well as a number of other human cancers. One gene within this region was identified, and the corresponding coding region of the gene represents a novel 47 kD protein.  A domain of this product has an exact match to the conserved catalytic domain of protein tyrosine phosphatases, indicating a possible functional role in phosphorylation events. Sequence analyses demonstrated that a number of exons of the gene were deleted in tumor cell lines used to define the 10q23.3 region, leading to the classification of this gene as a tumor suppressor.  Further analyses have demonstrated the presence of a number of mutations in the gene in both glioma and prostate carcinoma cells. Methods for diagnosing and treating cancers related to this tumor suppressor, designated as TS10q23.3, also are disclosed.

Patent CA-2314032-A1 (CA)
Title: Medium allocation method
Inventor: RUPP MARKUS
IPC: H04L12/56
Filed: 2000-07-13
Abstract: In a system in which the modulation scheme employed may change on a per-time-slot basis, a user's available data rate may change even if the user maintains the same number of time slots, because the capacity of the user's time slots may change. If one or more such changes in modulation scheme occurs, the data rate available to the user may no longer match his current data rate needs. Therefore, a method is disclosed for determining the number of time slots to assign to a user as a function of the user's current data rate requirement and the actual current cumulative data rate of the time slots currently assigned to the user. The user data rate requirement may further be a function of a quality of service (QoS) contracted for by the user. Thus, the assignment of the time slots within the frame is made dynamically and the number of time slots employed by a user is increased or decreased according to the user's current data rate requirements and the ability of the time slots already assigned to the user to meet those requirements.

Patent CA-2315989-A1 (CA)
Title: Fast gain control for optical amplifiers
Inventor: FEULNER MATTHIAS RICHARD
IPC: H04B10/29
Filed: 2000-08-14
Abstract: In an optically amplified wavelength division multiplexed (WDM) system having a WDM signal comprising a plurality of optical channels, the per-channel gain of the optical channels is kept relatively constant despite changes in input power at the optical amplifier, such as when individual optical channels of the WDM signal are added and dropped. More specifically, gain of an optical amplifier is controlled by controlling the amount of pump power supplied to the optical amplifier as a function of changes in input power which are measured in a feed-forward monitoring path. The amount of pump power for effecting gain control is adjusted according to a scaled relationship to the measured input power of the optical amplifier. By controlling the pump power directly in response to changes in input power, gain of the optical amplifier can be controlled within a sub-microsecond time scale from the time that a change in input power is detected.  Moreover, by maintaining relatively constant per-channel gain in an amplified WDM signal despite changes in input power at the optical amplifier, power excursions are substantially reduced in surviving optical channels of the WDM signal, i.e., those at the output of the optical amplifier.
