For use in conjunction with an existing wireless transmitter/receiver, a transmitter provided by the invention preferably uses some or all of the same codes as the existing remote transmitter to perform a desired function such as door or trunk unlocking, windows, light activation, and so forth. One embodiment of the invention includes a passive entry system so that only an authorized operator can use the device. In a preferred embodiment, a user carries a wallet-sized card or other device, such that upon activation of the keypad associated with the inventive transmitter, a signal is first sent to the user for verification. If the card or other device carried by the user properly transponds an appropriate authorization signal, the inventive transmitter broadcasts the codes appropriate to the function being requested. Alternatively, biometric information such a fingerprint or voiceprint may be used.

PCT No. PCT/US95/16649 Sec. 371 Date Sep. 2, 1997 Sec. 102(e) Date Sep. 2, 1997 PCT Filed Dec. 21, 1995 PCT Pub. No. WO96/19825 PCT Pub. Date Jun. 27, 1996Apparatus and process for conditioning a generally planar substrate, contained in a chamber isolatable from the ambient environment and fed with a conditioning gas which includes a reactive gas. The apparatus includes a support for supporting the substrate in the chamber, the substrate being in a lower pressure reaction region of the chamber. A gas inlet is provided for feeding conditioning gas into a gas inlet region of the chamber which is at a higher pressure than the lower pressure reaction region so that the pressure differential causes the conditioning gas to flow toward the surface of the substrate wherein the conditioning gas component will chemically react with and condition the substrate surface, both said higher and lower pressure regions operating in a viscous flow regime. The substrate is supported such that a pressure bias is created across the surface of the substrate so that the gas, after it has chemically reacted with the substrate surface, flows outward from where it has reacted, off the substrate toward the periphery of the chamber and out a peripheral or central underside exhaust outlet. Gas feed may be provided to one or both sides of the substrate and light activation of the substrate or conditioning gas may be provided on one or both sides.

“Smartmat” (Smartmat Area Activity Monitor and Personnel Identification System) monitors and identifies people, animals and other objects that pass through a control volume. Among other attributes, the exemplary system implementation can count, classify and identify objects, such as pedestrians, animals, bicycles, wheelchairs, vehicles, rollerbladers and other objects, either singly or in groups. Exemplary Smartmat implementations differentiate objects based on weight, footprint and floor/wall pressure patterns such as footfall patterns of pedestrians and other patterns. The system may be applied to security monitoring, physical activity monitoring, market traffic surveys and other traffic surveys, security checkpoint/gate monitoring, traffic light activation and other device activation such as security cameras, and other monitoring applications. Smartmat may be portable or permanently installed.

The invention is a locally mounted light source for light activation of tooth whitening compositions. A support in the form of a bridge attached to a retractor or as part of a mouth guard has integral therewith, a small and lightweight light source, such as could be provided by one or more high-intensity LED's, though other light sources could be used. The light source may be in the form of an array, powered by either a direct electrical connection to a power supply or by battery power, for example, with a battery pack worn by the user. The light source is thus located in proximity to the tooth surfaces regardless of head movement or orientation, increasing user mobility and comfort.

An artificial promoter system that can be fused upstream of any desired gene enabling reversible induction or repression of the expression of the gene at will in any suitable host cell or organisms by light is described. The design of the system is such that a molecule of the plant photoreceptor phytochrome is targeted to the specific DNA binding site in the promoter by a protein domain that is fused to the phytochrome and that specifically recognizes this binding site. This bound phytochrome, upon activation by light, recruits a second fusion protein consisting of a protein that binds to phytochrome only upon light activation and a transcriptional activation domain that activates expression of the gene downstream of the promoter.

The present invention relates generally to polymer composites having dispersed therein both useful spinel crystal fillers and ferroelectric (and/or paraelectric) fillers wherein the composite is both light activatable and can be used as a planar capacitor material. The light activation is typically employed via a laser beam (or other light emitting device) where the material has a pattern formed thereon. Electrodes are typically formed on the material's surface after patterning is complete via electroless metal plating. These composite polymers can be used as planar capacitors embedded in printed wiring boards or in integrated circuit packages.

A night light device that provides low level illumination, which turns on automatically when motion is detected near the device and only if the ambient lighting level is too low. The device operates using battery power and is only activated upon detecting both motion and low ambient light level simultaneously. The device will remain active for a period of thirty seconds unless additional motion is detected, in which case it will remain active for thirty seconds after the last detected motion. Two AA alkaline cells are expected to last for one year at an average of 35 light activations per day, resulting in usability and cost efficiency. The device may also be held in the hand for use as a low-lighting flashlight. Illumination with both functions is provided by a single light source, reducing the energy consumption and cost for the user.

A curing system for a photohardenable material is disclosed having an electrically powered light source and a variable power supply electrically connected to the light source. During calibration, a photocell determines the power output of the light source and produces an output signal representative thereof. A control circuit then controls the illumination of the light source by the power supply. This control circuit includes a comparator which compares the power output signal from the photocell with a target value and then varies or increases the power from the power supply to the light source up to a maximum power output whenever the power output signal from the photocell is less than the target value. Following calibration, the control circuit also activates the power supply for a time period sufficient to obtain a substantially constant energy output from the light source per light activation. In the event that the power output signal is less than the target value and also that the power supply is at its maximum power output, the control circuit increases the duration of illumination of the light source beyond a preset time period by an amount sufficient to obtain a substantially constant energy output from the light source per activation.
