Abstract: Disclosed herein is a Invention which communicates physical assistance to steering a conventional two wheel or three wheel motorcycle. As it can be used to fine tune a two wheel motorcycle. The invention when applied to a three wheel motorcycle, or also referred to as a tricycle, quite profoundly eases the steering input necessary by the operator. In a three wheel application, steering becomes harder proportionally as the vehicle is turned from straight a head to its maximum turning angle, right or left. This invention can be adjusted to all but eliminate, the input forces applied by the operator proportionately relevant to steering angle. Ease of installation and steering assist adjust ability plus ease of manufacture are also note worthy.

Abstract: A radiation sensor utilizing a single crystal semiconductor pyro-optical film to modulate a photonic carrier beam with energy in excess of the bandgap of the semiconductor for the purpose of detecting a first source of radiation. Specific implementations described here include a thin film of single crystal semiconductor made part of a suspended microplatform thermally isolated above an underlying substrate. The first source of low level radiation incident upon the microplatform and partially absorbed therein causes an incremental heating of the pyro-optical film. A second source of radiation comprised of a photonic carrier beam is incident on said microplatform and exits by reflectivity means or transmission means and is modulated by the pyro-optical effect with incremental heating of the platform and film. A detector or array of detectors monitors the intensity of the photonic carrier beam exiting the microplatform and thereby provides a sensitive means of monitoring the amplitude of the low level radiation.

Abstract: A thermal sensor or sensor array for detecting including imaging of low level radiation. The sensor utilizes a thin film of pyro-optical material to modulate the reflectivity and/or transmission of a photonic carrier beam. The photonic carrier beam is modulated by the temperature of the pyro-optical film and detected by typically a silicon detector. A slight increase in the temperature of the pyro-optical film due to absorbed low level radiation causes a corresponding change in the electrical resistance of heaters within each pixel of the thermal sensor array. An external fixed amplitude voltage or current source provides power to increase the temperature of the pyro-optical film beyond the heating caused by the absorption of low level radiation alone. This thermal amplification effect provides a radiation sensor with electro-thermal signal gain.

The invention also relates to aqueous dispersions of water insoluble heteropolymer particles which incorporate units of reactive amphiphile.

Abstract: This invention is a micromachined sensor pixel structure that can be fabricated either as a discrete sensor or in array form with application to thermal sensing of radiation receive from various wavelength emitters. The transmissivity of a thermally-isolated microplatform is a sensitive function of temperature. This transmissivity is modulated by incident radiation from sources including infrared sources. The transmissivity of a micromachined structure is interrogated by means of an optical carrier. Readout is obtained by means of conventional silicon optical sensors or imagers. A multiplicity of micromachined pixels can be tailored for specific wavelengths permitting the array to operate as a multispectral imager with windows ranging from ultraviolet to millimeter wavelengths.

Abstract: A process for producing a multilayered substrate. In a first step, an adhesive layer is applied to a surface of a support substrate. Then a device substrate is placed into contact with the adhesive surface. Then the adhesive is cured. Then the device substrate is thinned. The device substrate has a hydrogen trap layer inside. The trap layer is formed by ion implantation through a face surface of the device substrate. The adhesive is chosen from compounds that release hydrogen upon curing. Thinning of the device substrate is performed by cleavage along a fragile layer of hydrogen microbubbles. The microbubble layer is formed through gettering of hydrogen released from the adhesive layer upon curing onto the trap layer and evolving the trapped hydrogen into the microbubbles. The substrates are preferably silicon single crystalline wafers and the adhesive is preferably hydrogen-silsesquioxane.

Abstract: A magnetoresistive read/inductive write magnetic head assembly formed on a hard electrically insulating substrate and having electrostatic discharge protection comprises: a hard electrically insulating substrate, preferably formed of sapphire or alumina-TiC; multiple alumina layers formed over the substrate; a magnetoresistive read/inductive write head positioned between the alumina layers; a silicon layer supported by the substrate; and a semiconducting circuit integrated into the silicon layer and interconnected with said magnetoresistive read/write inductive write head to provide electrostatic discharge protection to the head. The silicon layer may be epitaxially grown on the substrate when implemented as sapphire, or bonded to the substrate when implemented as alumina-TiC. The hard electrically insulating substrate and alumina layers provide the assembly with a hard air bearing surface having generally uniform lapping and etching characteristics, and excellent durability.

Abstract: The invention relates to oral care compositions with colloidal anti-plaque agents which have been coated with particular polymers containing carbohydrate (saccharide) or peptide structures which are specifically recognised by bacterial adhesins, more particularly carbohydrate containing polymers recognized by bacterial lectins, or with antibodies or antibody fragments which recognize plaque bacterial antigens. Such coated colloidal anti-plaque agents, e.g. coated colloidal zinc oxide, can be target to specific sites in the human mouth where the anti-plaque agent is then released at acidic pH.

Abstract: A composite thin film slider with a protruding R/W device formed by chemical-mechanical polishing to protrude above its substrate and thereby reduce the distance between the R/W device and the recording media. The slider includes a ceramic or non-ceramic substrate with a substantially planar bearing surface, and a R/W device. The R/W device includes an insulator and certain conductive R/W components, deposited onto the substrate's deposit end. The R/W components may include, for example, a magnetic shield layer, a MR stripe layer, and a magnetic pole tip layer, all layered over the deposit end of the substrate. The R/W components protrude from the insulator sufficiently to extend past the substrate's bearing surface. To manufacture this slider, a substrate with the R/W device deposited thereon is polished with a lapping slurry to disproportionately erode the substrate and insulator with respect to the R/W components.
