Patent CA-2304822-A1 (CA)
Inventor: SINGLE PETER
IPC: A61F11/04
Filed: 1997-09-29
Abstract: A monitor for a therapeutic device such as a cochlear implant monitors the leakage RF signals between the external and the internal components. In one embodiment, absence of RF signals is interpreted by the monitor as being indicative of either an out-of-range condition or a flat battery condition and a sound and/or visual signal is generated to indicate this condition to an attendant. In a more complex embodiment, special indication signals either are superimposed on the standard signals and used to uniquely identify the cochlear implant or to provide an indication of certain preselected features of the external component. The monitor is especially useful where cochlear implants have been fitted to infants.

Title: Method and device for identification of a type of material in an object and utilization therefor
Inventor: FERBER ALAIN
IPC: G01N21/35
Filed: 1999-02-08
Abstract: A method and apparatus for identifying a material type in an article (20; 21), such as wholly or partly tranparent bottle of plastic or glass, including, with the aid of a detector station (1-16, 18, 19, 25), irradiating the article with rays from an infrared radiation source (1), detecting rays which have passed through the article non-absorbed, and then carrying out a correlation analysis of such detected rays. The article is made to pass through the detector station (1-16, 18, 19, 25) in a continuous or discontinuous movement.  The rays from the radiation source (1) are successively filtered by the filters (10) consisting of wholly or partly transparent materials which have different spectral characteristics. The rays filtered by the filters and non-absorbed by the article are intercepted in order to form a sequence of measured values representing characteristic transmission signatures of the article. A correlation analysis of the signatures is carried out in relation to statistical models in order to determine the material type of the article.

Abstract: An efficient free-piston internal-combustion engine (802, 811, 832, 14, 114, 314, 614) having an expansion ratio greater than the compression ratio. The engine has a gas bearing (804, 813, 831) and an exhaust temperature in excess of 600 ~C which are used to operate as a topping cycle for gas turbines, Stirling engines, steam engines, etc. An improved valving system for flexible control of the engine may include the use of a valve actuator (28, 32, 132, 410, 616) in a piston. In one embodiment, a pair of oppositely disposed combustion chamber passageways each have a combustion-chamber valve (132, 410) for controlling the passage of gas through the passageways. Variable control of the piston positions at which the valves are opened and closed permits the engine to operate at a high efficiency over a broad range of power output loading conditions. In another embodiment the combustion chamber and a gas compressor are combined in the same cylinder.

Abstract: A reel unit for supply and take-up of film from at least one motion picture projector includes an upright support column (42) and a plurality of film platter-support arms (44, 46, 48, 50 and 52) that extend generally horizontally from the column at vertically spaced positions. The arms are alternately offset laterally from one another to facilitate access to film on platters (P) below the top arm. Each arm carries a platter drive hub (70) provided with upwardly projecting drive pins (78) that engage in openings (34) in the platter so that the platter can be lifted off the arm. This allows the platters to be interchanged between different arms. Film take-up and pay-out cores can be interchangeably mounted on the platters so that any one platter can serve as a supply platter or a take-up platter irrespective of its position on the column. For the same reason, the column carries, in association with each arm, a set of rollers for guiding film being paid out from a platter on that arm or being wound onto the platter.

Patent CA-2329993-A1 (CA)
Inventor: KLOFT PETER
IPC: H03K17/97
Filed: 1999-04-08
Abstract: Generators for generating transient impulses of electrical energy, so-called impulse generators, are used for example for igniting a gas in gas burners or as percussion fuses for projectiles. The high speed required for changing the magnetic flux density in the time can only be achieved with the help of considerable forces such as those produced for percussion fuses for example. Manually activated generators are not usually capable of inducing comparatively high stresses because of the limited force which is applied. Percussion fuses must also be protected against accidental activation. Prior to the generation of the impulse of electrical energy, the inducing magnet is therefore in a starting position situated at a distance from the induction coil. At least one stationary magnet is located in front of the induction coil. This magnet produces a magnetic field whose polarity is oriented in such a way that it presents an obstacle to the inducing magnet in front of the induction coil. Elements are provided for enabling the inducing magnet to overcome this magnetic field in the direction of the induction coil.

Filed: 1999-04-23
Abstract: Methods and apparatus are disclosed that apply a predetermined complex-valued spectral transfer function to an input optical field to produce an output field that propagates in an output direction. Methods for making such apparatus are also disclosed. Segmented gratings (1915, 1916, 19a15, 19a16) fabricated according to one example comprise a series of spatially distinct subgratings arrayed end to end. Each subgrating possesses a periodic array of diffraction structures, such as lines or other elements. The transfer functions of such segmented gratings are determined by controlling (a) the spatial periodicity or frequency of each subgrating, (b) the amplitude of each subgrating, (c) the spacing between the last diffraction structure (or line) on each subgrating and the first diffraction structure (or line) of the successive subgrating, and (d) the optical path length and transparency through each subgrating, or each subgrating plus additional material layers utilized to control optical path length and transparency. Communication systems using such segmented gratings are also provided.
