Abstract: A control system and method for a dryer used to dry a line of gypsum boards.  The control system automates control of the dryer by measuring the amount of water used at the mixer to produce board segments and determining a desired amount of water to be evaporated for each board segment based on the measured value. The desired amount of water to be evaporated for each board segment is tracked through the production line and the total evaporation load of each dryer zone is continuously calculated based on the board segments located in the dryer zone at a given time. The dryer zone differential temperature is adjusted according to the calculated evaporation load. When a board is rejected from the board line, the desired amounts of water to be evaporated of its corresponding board segments are set to zero, thus signifying a gap. The control system can be implemented using a distributed control concept, with PLC's controlling major process areas, and networked PC based supervisory operator interfaces located at key locations throughout the production line.

Granted: 2004-07-06
Abstract: An integrated receiver decoder (IRD) (37), commonly called a set-top box (37), has a global positioning system (GPS) receiver (44). The GPS receiver (44) checks to see if the IRD is as an authorized location and allows descrambling (46) of video signals only if the location is authorized. A central access control system (48), remote from the customers/viewers, has a high quality GPS receiver and sends some GPS data in the transmission medium used to send video signals to the customers. The set-top box (37), referred to as a customer access control, establishes different geographic restrictions on different of various video signals. Location-specific signals require that the set-top box be at a single fixed location for descrambling. Region-specific signals are accessible only if the set-top box (37) is in a geographic region authorized for reception, there being several such regions.

Abstract: A waste water insert (46) has a cylindrical wall (52) surrounding a central opening (54). A horizontal flange (48) extends outwardly from the upper end of the wall (52) and has a lip (50) formed on its outer periphery. The horizontal flange (48) is superimposed over a conventional waste water strainer (20) located in a bathtub, sink or the like.  The lip (50) fits over the outer periphery of the horizontal flange (24) of the waste water strainer (20) to center the insert on the strainer (20). The cylindrical wall (52) of the insert (46) extends downwardly through the conventional cylindrical wall (30) of the waste water strainer (20) with the two walls being spaced from each other by virtue of the cylindrical wall (52) of the insert (46) having a smaller diameter than that of the strainer. A sealant material (58) is placed between the horizontal flanges (48) of the insert (46) and the strainer (20) and provides the sole means of attachment between the insert (46) and the strainer (20).

Abstract: La présente invention concerne un appareil et des procédés d'évaluation d'une fonction neuromusculaire. A l'aide d'un appareil de l'invention, on applique des stimuli à un nerf que traverse le poignet d'un individu. On applique les stimuli à un point proximal du poignet. La stimulation du nerf provoque une réponse du muscle innvervé par ledit nerf. La réponse du muscle produit un potentiel myoélectrique détecté par l'appareil de l'invention à un point proximal du poignet. L'intervalle de temps entre la stimulation d'un nerf et la détection d'une réponse musculaire à ladite stimulation est traité de manière à évaluer une fonction musculaire. Un délai suffisant entre l'application d'un stimulus et la réponse d'un muscle peuvent indiquer, par exemple, la présence d'un syndrome du canal carpien.

Title: Transcription based amplification of double stranded dna targets
Inventor: SCHUKKINK ADRIANA FREDERIEKE
IPC: C12Q1/6865
Filed: 1998-11-11
Granted: 2007-07-03
Abstract: The present invention is directed to a transcription based amplification method for the amplification of DNA targets. With the method of the present invention an isothermal transcription based amplification method is provided for the amplification of double stranded DNA. The method of the present invention for the amplification of double stranded DNA comprises the steps of contacting said double stranded DNA with at least one oligonucleotide comprising a sequence complementary to a part of the first of the two DNA strands comprised in the double stranded DNA, said oligonucleotide further comprising the sequenc e of a promoter recognized by a RNA polymerase; a further olignucleotide comprising a sequence complementary to a part of the second strand comprised in the double stranded DNA; an enzyme having RNA dependent DNA polymerase activity; an enzyme having DNA dependent DNA polymerase activity; an enzyme having RNase H activity; an enzyme having RNA polymerase activity; and maintaining the th us created reaction mixture under the appropriate conditions for a sufficient amount of time for the amplification to take place. The method according to the invention is particularly useful for amplifying small DNA molecules, e.g. plasmid DNA. Surprisingly, transcription based amplification can startfrom double stranded DNA, without the need to treat the DNA with restriction enzymes or, what is more importan t, to separate the strands before hand by applying heat. All reagents conventionally used with isothermal transcription based amplificati on reactions can simply be used on starting material containing double stranded DNA, as if it where single stranded RNA. With the present invention it has now been found that essentially the same protocols can be used for isothermal transcription based amplification of double stranded DNA. The method is particularly useful for the detection of small DNA molecules of pathogenic microorganisms enabling diagnosis. In particular the circular HIV-1 DNA molecules that are formed during the replication of the HIV-1 virus can be detected by this method. Detection of such circular HIV-1 DNA molecules indicates active replication of the virus, which can be correlated with disease progression, i.e. development of AIDS.

Abstract: An air drag reducing apparatus for use with a vehicle having a rear end closed by a pair of doors consists of a rectangular shaped panel having a leading edge hingedly connected to the vehicle, the panel extending at about 15 degrees relative to the rearward projection of a side of the vehicle. An element positions the panel in a drag reducing position; this element is such that it allows the panel to be moved between the door and the side of the vehicle as the door is opened and moved to a position adjacent the side of the vehicle. As the door is moved back from the opened position to a closed position, the element causes the panel to return to its drag reducing position. The rear of a vehicle may include two side panels with or without two top panels.

Title: Host rejection filtering in a digital audio broadcasting system
Inventor: NEASE GREG ALAN
IPC: H04J11/00
Filed: 2000-10-17
Granted: 2004-12-28
Abstract: A digital receiver for receiving an analog host signal with one or more digital sidebands includes a bandreject filter arranged at least in part in an intermediate frequency (IF) processing stage of the receiver. In an illustrative embodiment, first and second digital sidebands are transmitted on either side of a frequency modulated (FM) analog host signal in a hybrid in-band on-channel (HIBOC) digital audio broadcasting (DAB) system. The received composite signal is filtered in the IF processing stage of the receiver by the bandreject filter in order to substantially attenuate the analog host signal while passing the digital sidebands. The bandreject filter may be arranged in the IF processing stage so as to filter the analog host signal from the composite signal at a point prior to an input of an automatic gain control (AGC) circuit, such that the AGC operating point is determined primarily by the digital sidebands. The bandreject filter may have a group delay characteristic for a portion of a frequency spectrum associated with the digital sidebands that is selected to equalize a corresponding group delay characteristic for a signal path of the receiver.
