Title: Natural insect and arthropod repellent
Inventor: REIFENRATH WILLIAM G
IPC: A01N63/10
Filed: 1998-06-30
Abstract: A topical insect repellent with extended duration of protection was obtained from mixtures of molecules based on two or more volatile repellent organic molecular species occurring naturally on human skin surfaces. The novel repellent comprises mixtures of lower, intermediate, and higher volatility organic molecules. Active ingredients for formulations are obtained from homologous series of carboxylic acids, alcohols, ketones, and lactones which span a similar range of volatility and which occur naturally on the skin surface. Volatile silicone fluid imparts mildness and water repellency to the repellent formulations. The inventive repellent exhibits longevity and repellency that is comparable to DEET. The inventive repellent, formulated in a volatile silicone fluid, was shown to repel and incapcitate stable flies. Repellency extends to mosquitoes and other biting flies or insects.

Title: Beneficial agent delivery system with membrane plug
Inventor: LAUTENBACH SCOTT D
IPC: A61K9/00
Filed: 1998-07-24
Abstract: An osmotic delivery system for controlled delivery of a beneficial agent includes an implant capsule containing a beneficial agent and an osmotic agent which swells on contact with water causing the release of the beneficial agent over time. The osmotic delivery system has a membrane plug which allows water to pass through the plug from an exterior of the capsule while preventing the compositions within the capsule from passing out of the capsule. A delivery rate for delivery of the beneficial agent from the implant capsule is controlled by varying a core diameter of the membrane plug within a constant diameter capsule. The membrane plug has a variable water permeation rate depending on an extent to which the membrane plug is constrained by the capsule walls.

Patent CA-2326709-A1 (CA)
Inventor: HUBER FELIX
IPC: B60R25/10
Filed: 1999-02-19
Abstract: Electronic anti-theft devices can be circumvented by exchanging or bridging critical components in a shielded manner. The present new invention avoids this by making the protection a functional part of the object to be protected.  The security device, for example in a motor vehicle, is activated by irreversibly deactivating and/or deleting at least one of the components (5, 6, 7, 8) and/or information within at least one of these components (5, 6, 7, 8) essential for running the vehicle. In this way even the removal or bridging of the component concerned has no effect since the acquisition of a functional replacement part becomes unavoidable. The components can be housed, for example, in the engine electronics centre (6), the steering wheel lock (7), the door lock (8) and/or the key (5). By miniaturizing the receiver any electronic device can be protected, including mobile telephones, (Euro)cheque and cash cards, credit cards, telephone cards, keys for electronic locking devices, mobile electronic devices such as cassette decks, CD players, watches, computers, etc.

Abstract: By a parallel time-multiplexing method, the weighted mean of pilot symbols a re calculated and a channel estimation of a data symbol of a data channel is calculated. The data symbol in a slot is divided into data symbol sections. A pilot symbol suitable for the calculation of the channel estimation of the data symbol of each data symbol section is selected. The weighted mean of th e selected pilot symbols is calculated and a channel estimation of the data symbol of each data symbol section is calculated. The weights are varied wit h the fading frequency determined based on the inner product of the pilot symbols. Received data is demodulated by use of the channel estimation determined by calculating the weighted mean of the pilot signals by using a plurality of weight series. A piece of output data the quality of which is best is selected by judging the reliability of demodulated data.
