Filed: 1996-06-06
Granted: 2002-02-05
Abstract: A multi-signature fire detection method and apparatus, utilizing first (1) and second (2) detectors for detecting first and second signatures. The first (1) detector outputs a first signal (A) indicative of the first detected fire signature, and the second detector (2) outputs a second signal (B) indicative a second detected fire signature. A signal processor (3) is provided for combining the first (A) and second (B) signals using a number of correlations, wherein outputs of the first (1) and second (2) detector means are coupled to the signal processor (3), and the signal processor (3) compares and combines the first (A) and second (B) signals to a first predetermined reference value (303), and outputs a fire condition signal if a combination of the first (A) and second (B) signals exceeds the predetermined reference value (303).

Abstract: A wheel mounting assembly (10) for use in a children's ride-on vehicle having a frame (12) includes a cross member (30) extending transversely of the frame providing a mount (42 44) for two of the vehicle's opposed wheels ( 14), and frame-formed support structure in the form of two downwardly extending plates (18, 20) defining a slot (22) for receiving the cross member and providing a mount on which the cross member is fastened. The plates have plural spaced apertures (20a, 20b) therein and the cross member has apertures (34a, 34b, 34c, 34d) which align with the apertures in the plates. Fastening mechanisms in the form of a bolt (35, 37) passing through the aligned apertures and secured in place by a nut (35a, 37a) fix or mount the cross member to the plates. Pairs of vertically spaced apertures in the wall structure enable the cross member to be selectively vertically positioned relative to the plates for accommodating different-sized wheels.

Title: Capo device for stringed musical instrument
Inventor: SIMS CHRISTOPHER GEORGE
IPC: G10D3/04
Filed: 1998-08-10
Granted: 2000-11-21
Abstract: A capo device for a stringed musical instrument having a series of strings extending along a fretboard with spaced frets, in which each string passes through a bore in an element which is slidable on the string, each element being dimensioned so that when held against the fretboard the element stops the string on which it is mounted at the adjacent fret. The elements and the fretboard have interacting magnetic means capable of holding each element against the fretboard at one of a number of selected positions during the playing of the instrument, while allowing the element to be moved to a stored position when not in use. The stored position is usually between a string nut or zero fret, and a string guide which contacts the strings between the nut or zero fret and tuning pegs for the strings, the elements being movable over the nut or zero fret into the stored position.

Abstract: Tension-type headache is treated by interacting with neuronal transmission in relation to pain in connection with headache in a way which prevents or decreases sensitization of second order nociceptive neurons. In particular, treatment is performed by administration of an effective amount of a substance which prevents or decreases central sensitization. Important examples of such substances are substances which interact with glutamate neurotransmission, such as glutamate receptor antagonists, such as NMDA receptor antagonists, such as MK-801 or Amitriptylline or Imipramine or Desipramine or Mirtazaprine or Venlafaxine. Other examples are substances which interact with nitric oxide, such as nitric oxide synthase (NOS) inhibitors, such as L-NMMA or L-NAME or L-NIO or L-NNA. According to a broader aspect of the invention tension-type headache is treated by administration of substances which are effective in preventing or decreasing pain in connection with tension-type headache, such as the substances mentioned above. An additional aspect of the invention relates to treatment of tension-type headache by administration of substances which substantially inhibit the activity of nitric oxide synthase (NOS), such as NOS inhibitors, such as L-NMMA or L-NAME or L-NIO or L-NNA.

Abstract: This invention is directed to a multi-layer laminated shingle, wherein each shingle layer comprises granule and bituminous coated web, with the layers laminated together and with the butt zone of the base layer disposed against a bottom surface of the tab zone of the secondary layer and with the tab zone of the base layer disposed against the bottom surface of the butt zone of the secondary layer. The shingle lends itself to having tabs spaced by voids. Because the tabs in the base layer are inverted, the base layer's butt zone is visible through voids in the tabs of the secondary layer.        The method of making the shingle lends itself to complementally cutting out the tabs of two side-by-side shingles from a given line. Enhanced nailing area is provided, and stacking of shingles for packaging is facilitated.

Abstract: A method and apparatus for automatically locating sources of semantic err or in a mufti-agent system based on setup connection tree information, and informing the appropriate agents so that they can avoid using the faulty resources in the future. The setup connection tree model is established based on patterns of agent action s for expressing the logical relationship between available resources in the disjunctive normal form (d.n.f.). A table is used to record different sets of resources for use in the resource selection process. Thus, faulty resources can be located by means o f induction. A global database is also maintained for updating information on semantic errors in the system.
