Abstract: A power saving device for a light emitting diode (LED) lamp mounted to an existing fixture for a fluorescent lamp having a ballast assembly and LEDs positioned within a tube and electrical power delivered from the ballast assembly to the LEDs. The LED lamp includes means for controlling the delivery of the electrical power from the ballast assembly to the LEDs wherein the use of electrical power can be reduced or eliminated automatically during periods of non-use. Such means for controlling include means for detecting the level of daylight in the illumination area of said least one LED in particular a light level photosensor and means for transmitting to the means for controlling a control signal relating to the detected level of daylight from the photosensor. The photosensor can be used in operative association with an on-off switch in power connection to the LEDs, or with a computer or logic gate array in operative association with a dimmer that controls the power to the LEDs.

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 power saving device for a light emitting diode (LED) lamp mounted to an existing fixture for a fluorescent lamp having a ballast assembly and LEDs positioned within a tube and electrical power delivered from the ballast assembly to the LEDs. The LED lamp includes means for controlling the delivery of the electrical power from the ballast assembly to the LEDs wherein the use of electrical power can be reduced or eliminated automatically during periods of non-use. Such means for controlling can include an on-off switch mounted in the tube or can also include a current driver dimmer mounted in the tube that regulates the amount of power delivered to the LEDs. A computer or logic arrays control the dimmer or power switch. A sensor such as an occupancy motion detection sensor mounted external to the tube or within the tube can send signals to the computer or logic array to trigger a switch or control a dimmer.

Abstract: An LED lamp for mounting to an existing fluorescent lamp fixture having a ballast assembly including ballast opposed electrical contacts, comprising a tubular wall generally circular in cross-section and having tubular wall ends with one or more LEDs positioned within the tubular wall between the tubular wall ends. An electrical circuit provides electrical power from the ballast assembly to the LED(s). The electrical circuit includes at least one metal substrate circuit board and means for electrically connecting the electrical circuit with the ballast assembly. The electrical circuit includes an LED electrical circuit including opposed electrical contacts. Each metal substrate circuit board supports and holds the one or more LEDs and the LED electrical circuit. Each metal substrate circuit board is positioned within the tubular wall between the tubular wall ends. At least one electrical string is positioned within the tubular wall and generally extends between the tubular wall ends.

Abstract: A cut-resistant and shred-resistant absorbent sheet material including an absorbent substrate and cut-resistant particles distributed through the substrate. Preferably, the absorbent substrate comprises cellulosic material and the particles comprise polymeric materials having an average size of at least about 100 micrometers, and most preferably between 100 and 1000 micrometers. It is also preferred that the absorbent substrate is provided in an amount of at least 50 percent by weight and is substantially free of inorganic free filler particulate. In addition, it is preferred that the sheet material has a basis weight of at least 100 pounds per 3000 ft2, and that the particles are provided in an amount of between about 10 percent and about 50 percent by weight of the sheet. The sheet material can be made using typical paper making processes. Preferably, heat and/or pressure are applied to the sheet material to cause the particles to at least partially flow, so as to bond to the absorbent substrate.

Abstract: A multi-purpose sheet material comprising an absorbent layer and a cut-resistant material in contact with the absorbent layer. The cut-resistant material can comprise a cut-resistant support system, such as cut-resistant support element formed in the absorbent layer for example. The cut-resistant material may alternatively comprise cut-resistant particles, such as polymer particles having an average size of at least about 100 micrometers for example. Preferably, the sheet material exhibits an absorbent efficiency of at least about 0.2 and a slice resistance of at least about 30 kgf/cm, and more preferably an absorbent efficiency of at least about 1.0 and a slice resistance of at least about 40 kgf/cm. It is also preferred that sheet material exhibit a cut-resistance of at least about 30 kgf/cm, an absorbent efficiency of at least about 0.2, and a wet abrasion loss of less than about 400 mg per 100 revolutions.

Abstract: The present invention provides a liquid absorbent fibrous substrate having a plurality of discontinuous cells in which a second material is disposed. This second material is selected from a broad variety of organic or inorganic solids which may provide a reinforcing effect such that a sharp instrument is prevented from passing through the new composite structure. The reinforcing materials are disposed in a discontinuous array, in a cellular form in the fibrous substrate thus providing a path for liquids to be absorbed into said fibrous substrate, while said reinforcing materials provide resistance to penetration by sharp edged instruments. When disposed in this manner, flexibility is maintained since the reinforcing materials are not disposed in a continuous pattern. Preferably, the pattern disposed is free of linear regions that provide a continuous line of penetration for sharp edges.
