30results about How to "Potential for interference" patented technology

Generally, this invention relates to the development of field monitoring methodology for new substances and sensing chemical warfare agents (CWAs) and terrorist substances. It also relates to a portable test kit which may be utilized to measure concentrations of halogenated volatile organic compounds (VOCs) in the field. Specifically it relates to systems for reliably field sensing the potential presence of such items while also distinguishing them from other elements potentially present. It also relates to overall systems and processes for sensing, reacting, and responding to an indicated presence of such substance, including modifications of existing halogenated sensors and arrayed sensing systems and methods.

Disclosed is a method for a femtocell to reduce interference with an overlapping macrocell. The femtocell determines soft-frequency-reuse (“SFR”) information of the macrocell. From that information, the femtocell determines which frequency sub-channels are assigned by the macrocell for its cell-center users and which frequency sub-channels are assigned for cell-edge users. (Cell-edge users are given a higher transmission power profile in order to overcome potential interference with neighboring macrocells.) Then, the femtocell selects from the cell-center user frequency sub-channels for transmission to the femtocell's users. By transmitting on the cell-center user frequency sub-channels, the femtocell reduces interference with the overlapping macrocell. The femtocell continues to update its knowledge of the macrocell's SFR information and re-assigns frequency sub-channels as the SFR changes. If the macrocell detects that one of its cell-center users is “close enough” to the femtocell, then the macrocell re-assigns the cell-center user as a cell-edge user to overcome interference.

An air dam is attached to the underside of a vehicle and extends downwardly into proximity with the road surface and potential interference with curbs or like obstructions extending above the road surface. A panel assembly includes a top wall attached to the underside of the motor vehicle, forward and rearward walls depending from the top wall, and a bottom wall. These walls cooperate to define an interior space, and the forward and rearward walls have serially arranged pleats connected by living hinges by which the panel assembly can adjusted in height by flexing the living hinges to provide an extended position of the panel assembly in which the bottom wall is positioned further below the underside of the motor vehicle and a withdrawn position in which the bottom wall is withdrawn upwardly closer to the underside of the motor vehicle to avoid potential interference with curb or like obstructions.

A disc protector is described for use in the field of optical data storage discs where commonly known applications are compact discs (CD), digital versatile discs (DVD) and super audio compact discs (SACD). In particular a method to improve disc-holders is described where a protective material is present between the data-access surface of the disc and the disc-holder.

Exemplary embodiments of the present invention illustrate a probability time division multiplexing polling method and a wireless identifier reader controller thereof. The probability time division multiplexing polling method is used to control a plurality of wireless identifier readers to be turned on or off. First, one of the wireless identifier readers is randomly selected according to a probability model, wherein the probability model presents the probabilities for detecting an identifier tag of the wireless identifier readers. Then, the selected wireless identifier reader is turned on for a predetermined time period.

A self-testing circuit interrupting device including Ground Fault Circuit Interrupter protection, the circuit interrupting device usable with single phase power where a test pulse is injected into a falling edge of the electrical signal at a point greater than 54.2% of the maximum amplitude of the electrical signal. The circuit interrupting device usable with dual phase power where the test pulse is injected into a falling edge of the electrical signal at 0.879 ms from a minimum amplitude of the electrical signal.
