Patent CA-2101501-A1 (CA)
Inventor: WANG ROBERT C
IPC: H04B17/00
Filed: 1993-07-28
Abstract: METHOD AND APPARATUS FOR DETECTING A SUPERVISORY                    AUDIO TONE Abstract The presence of a supervisory audio tone signal (SAT), superimposed on a voice/data signal transmitted in a cellular telephone system, is carried out by first deleting the voice/data signal, leaving only the SAT signal. Thereafter, the SAT signal power and noise power are determined. During intervals when the SAT signal rises and falls, the SAT noise power and signal power move in opposite directions. By comparing the SAT noise power to the SAT signal power, a fast, accurate determination can be made as to whether the SAT signal is present.

Title: Method for manufacturing of subcutaneous capsules
Inventor: HARTZELL ROLF
IPC: B65B1/02
Filed: 1991-03-28
Abstract: The invention relates to a method for manufacturing subcutaneous capsules. The capsules are produced by cutting from a silicone tube lengths in excess of the final capsule length. The lenghts are arranged into rows including a defined number of them and in these rows they are filled and sealed. One end of the capsules is first sealed by glue dosaged into their openings. The material for the capsules is dosaged by an aperture disc glidable on a plane surface. By sweeping the upper surface of the disc the dosage volume is limited to the volume defined by the aperture. To regulate the packaging density of the material vibration may be used during the filling of the apertures. The dosaged material is conveyed to the capsule via a feeder funnel, through which a rotatable spiral spring, functioning as a filling screw, is inserted into the capsule to be filled.

Patent CA-2126681-A1 (CA)
Inventor: SINGELYN JAMES D
IPC: H01M8/02
Filed: 1992-12-14
Abstract: A porous plate used in a fuel cell is sealed with an essentially 100 % active material and catalyst mixture. The mixture is absorbed into and fills essentially the entire void volume provided by the pores. The mixture is then thermally shocked to partially cure the mixture thereby preventing wicking. The partially cured mixture is then post cured by elevating the temperature such that the catalyst initiates free radical polymerization. Since the sealant is essentially 100 % active, there are no escape paths formed during the curing process, and the final seal is essentially 100 % leak proof.

A threat data management system (212) and a raw threat positioning system (214) accepts aircraft beading (226) and angle of arrival of the threat (229) to generate a threat status indicator (216) and a threat position measurement (224). Navigation filtering management apparatus (218) accepts the threat status indicators (216) and provide position filter controls (220). Parallel estimation navigation filters (270) use the position filter control (220) and the threat of position measurements (224) to generate estimated threat positions for a number of threats (241, 242, 243, 244, 245). The estimated threat positions (241, 242, 243, 244, 245) are updated and threat situation awareness is presented to the pilot in real-time. Elevation extraction apparatus (256) uses a terrain data base (272) and the threat estimated position (241, 242, 243, 244, 245) to predict the elevation of the threat. Threat data including latitude, longitude and elevation is provided to other systems.
