Patent CA-2216263-A1 (CA)
Inventor: KISS BILL
IPC: H01H9/16
Filed: 1997-09-23
Abstract: A switch for use in an AC circuit wired in a three-way switch mode for supplying power to a load, has a first terminal for-connection to an external line, second and third terminals for connection respectively to corresponding terminals of a second like switch, and a switch contact for selectively connecting the first terminal to either one of the second and third terminals. A transformer has its primary winding connected between the first terminal and the external line, and its secondary winding deriving an output voltage therefrom. The output voltage is rectified and supplied to a light-emitting diode. The ratio of turns of the windings of the transformer is such that the rectified voltage energizes the light-emitting diode when power is supplied to the load over its normal operating range. The light-emitting diode will thus provide an indication of when power is supplied to the load.

Patent CA-2224992-A1 (CA)
Inventor: ABU-DAYYA ADNAN
IPC: H04L27/38
Filed: 1996-06-26
Abstract: A method of carrier recovery in a wireless communications system using a known synchronization word, for example an IS-54 TDMA system, operates in two stages to produce an estimate of carrier phase. In the first stage, a complex fading factor, embodying carrier phase information, is estimated from the synchronization word in the received signal using at least square criterion.  In the second stage, the carrier phase is estimated from this complex fading factor by averaging. The averaging can provide a recursive average or a moving average, or can be implemented using Kalman filtering which also provides an estimated amplitude factor and frequency shift. The method and apparatus provide a substantial improvement over phase locked loop carrier recovery.
Patent CA-2229798-A1 (CA)
Title: Canoe/kayak paddling simulator
Inventor: STEVENSON FRANCES K
IPC: G09B9/06
Filed: 1998-02-17
Abstract: The invention is directed to an apparatus for (and corresponding method of) simulating an outdoor activity such as paddling a canoe or kayak. The invention provides a user station for locating the user in optimal position for simulating the paddli ng motion. A resistance mechanism generates a resistive force opposing the paddling motion pe rformed by the user. This resistive force approximates the resistive force of water othe rwise encountered during paddling of a canoe or kayak on a body of water. A cross-over mechanism provides flexibility by permitting the paddling stroke to be equally p erformed on either side of the user. This cross-over may be done "on the fly" so the user need not interrupt the paddling exercise or training session.

Abstract: For a world that has a portion of the world distant from the point of view of th e user represented in only two dimensions as a video on a video screen, when an ob ject on the video screen undergoes a trajectory that takes at least a portion of it to a location in the world that is not represented by the video but instead is a location in the world that is represented by computer graphics, in addition to being able to continue to see s uch an object when it is rendered as computer graphics in the computer graphics part of the world, i.e., popped out from the video, one is able to interact with such an obj ect. Thus, an object which pops out from a video into the computer graphics part of the wor ld may be "investigated" by a viewer of the world. For example, the user could enter a store which popped out of the video, and engage in virtual shopping therein. The parti cular store which is actually entered may be customized on a per user basis, e.g., as a function of geography. When the proprietor of a virtual store, or his representative, e.g ., electronic agent, detects the avatar of one or more persons in the vicinity of the avatar o f a store for which such proprietor's store corresponds to the virtual store for such passing persons, a message may be transmitted to such passing persons.

Title: Fault-tolerant optical routing switch
Inventor: WU KUANG-YI
IPC: H04B10/27
Filed: 1997-06-30
Abstract: An electromagnetically controlled optical switch (100) having a plurality of optical inputs (101). An optical signal at each input (101) is spatially decomposed into two coparallel, orthogonally polarized beams by a birefringent element (130). An array (140) of field-controlled polarization rotators are positioned in the paths of the decomposed light beams so that the polarization of the emergent beam pairs are set to be at one of the orthogonal states (i.e., both beams are either vertical or horizontally polarized). A following birefringent element (150) spatially routes the light beam pairs based upon their polarization. A second array (160) of polarization rotators follows the second birefringent element (150) and is set to be in the opposite state from the first array (140), such that the emergent beams are orthogonal to their input states before they entered the first polarization rotator (140). The beams are combined by a firefringent element (170) to form a plurality of combined beams that are coupled to output ports (102, 103).
