All three types of UV LEDs are energized at the same time or individually to the same at least one target object being at least one smoke collection holder and capturing device having a coated surface that will fluoresce and glow when there is the presence of a wide range of smoke chemical particulates that have been collected, captured, and held in the at least one smoke collection holder and capturing device. This positive detection and confirmation indicates an act of smoking had recently occurred in the space where the at least one smoke collection holder and capturing device was installed, necessitating additional affirmation testing and recovery costs charged back to the smoker or occupant of the space where the act of smoking had taken place.

Abstract: A shield for protection of the back splash and wall behind a stove, providing an expandable shield suspended behind the stove while the stove is in use, the shield expanded into a deployed position and attached to the wall and secured within an upper shelf upon a support, the shield further stored behind the stove in a contracted position upon a lower shelf of the support, with the support mounted to either the wall behind the stove or upon the stove itself on a rear potion of the stove. The shield may also be used upon the back splash of a sink or other cooking station where protection of the back splash is desired.

Abstract: A Shabbat bulb and a related method allows control of illumination without electrical intervention by a person observing strictures of Shabbat orthodox Jewish law. The bulb includes a blackout mechanism with shutter disc having at least one disc aperture for transmission of light and gear teeth; and an arm projecting radially outward from the shutter disc fitted with drive gear teeth. Manual rotation of the arm engages drive gear teeth with shutter disc gear teeth moving the disc apertures from an open to a closed position respectively allowing full or totally no illumination to exit the bulb.

Abstract: Compositions and methods for diagnosing, treating and/or preventing cancers characterized by CDH17 overexpression based on the detection of CDH17 or the use of CDH17 as a target for therapeutic intervention or prophylactic intervention are provided. Methods for diagnosing and/or monitoring liver cancers using the expressing of CDH17 involve detecting and/or quantitating the CDH17 protein or encoding nucleic acids (DNA or RNA) in a biological sample such as urine from the subject. Methods for treating liver cancers using CDH17 as a target and of sensitizing cells with aberrant expression of CDH17 have also been developed. The methods include suppression or knockdown of the expression of CDH17 by administering an effective amount of a CDH17 inhibitor.

Abstract: A diode light source for theatrical and architectural lighting has a number of separate, flat, rigid panels for mounting light-emitting diodes. These emit diode light beams to a common focal area. A group of the diodes is mounted on each panel, and each panel has an inner and outer panel. A screw arrangement selectively positions the panels, with each oriented at a selected angle relative to an axis, and with each diodes group emitting diode light beams transverse to each separate panel. Each inner panel is flexibly secured to the screw arrangement. The panels hold the diodes and act as electrical circuit boards for transmitting direct electrical current to the diodes on the panels. The screw includes an elongated, externally threaded cylinder with opposed inner and outer ends that is rotatably aligned with the axis and mounted on a corresponding internally cylindrical threaded nut.

Abstract: A satellite TV security system including a TV satellite operated by a satellite TV provider directed to a television set of a satellite TV subscriber that defends the satellite TV provider from illegal reception of TV signals from a TV satellite. An addressable integrated receiver/decoder (IRD) positioned in the TV set top box has an assigned identification number and a smart card positioned in the IRD has an assigned identification number. A security module is provided that is integrated with the IRD. Upon command of the satellite TV provider or automatically, the security module makes a periodic verification of a match of the two identification numbers. Lack of verification of a match triggers a signal from the security module to the IRD to stop transmitting TV signals to the subscriber television. As an alternative verification, the security module initiates periodic verifications of the operability of the telephone line connection between the satellite TV provider and the IRD of the subscriber.

Abstract: A LED luminaire track lighting system includes an elongate track, having a number of longitudinal guideways, for attachment to a support surface, as well as a number of current conductors arranged within at least some of the guideways. The first of these conductors are power conductors and the second conductors are data conductors, the conductors being electrically isolated from each other. The lighting system further contains a first adapter for connection to a source of electrical power for the power conductors, and a second adapter for connection to a source of control data for application of data to the data conductors. There is at least one LED color-changing luminaire present in the system, and this luminaire contains a number of LEDs, each of which, when energized, generates a single color out of a discrete plurality of colors. A data converter converts data along the data lines to control the currents in the individual groups of color LEDs so that they create a desired composite color.
