Title: Child Carrier with Kickstand
Inventor: MEESEY CHRISTOPHER J
IPC: A47D13/02
Filed: 1996-05-03
Abstract: A child carrier for supporting a child adjacent the back of a hiker's torso comprises a forward portion and a rearward portion.  A child compartment is between the forward and rearward portions for receiving a child. A generally rigid frame member is operatively connected to and adjacent the rearward portion of the child carrier.  A kickstand having a ground-engageable portion is operatively connected to the frame member via a hinge for pivotal movement of the kickstand relative to the frame member about an axis X.  The kickstand is pivotally moveable between a retracted position in which the ground-engageable portion of the kickstand is positioned generally adjacent the frame member, and a propping position in which the ground-engageable portion of the kickstand is positioned away from the frame member.  The kickstand, hinge, and frame member are shaped and configured for maintaining at least a minimum spacing between the kickstand and frame member for preventing hands  and fingers of the child seated within the child compartment from being pinched between the kickstand and frame member during pivotal movement of the kickstand relative to the frame member.

Title: Method and apparatus for non-invasive detection of physiological chemicals, particularly glucose
Inventor: SMALL GARY W
IPC: G01N21/35
Filed: 1995-02-07
Abstract: Non-invasive measurements of physiological chemicals such as glucose are made using infrared radiation and a signal processing system that permits the construction of a device suited for home use. The level of a selected physiological chemical in a test subject is determined in a non-invasive and quantitative manner by a method comprising the steps of: (a) irradiating a portion of the test subject with near-infrared radiation such that the radiation is transmitted through or reflected from the test subject; (b) collecting data concerning the transmitted or reflected infrared radiation using a detector, (c) digitally filtering the collected data to isolate a portion of the data indicative of the physiological chemical; and (d) determining the amount of physiological chemical in the test subject by applying a defined mathematical model to the digitally filtered data. The data collected may be in the form of an absorbance spectrum, i.e., a representation of the variation in absorbance as a function of wavelength; a single beam spectrum or in the form of an interferogram, i.e., a representation of infrared light intensity as a function of the retardation of the moving mirror in the interferometer, and thus of time.

Title: Home test kit and method with telephone verification of results
Inventor: ZWANZIGER RON
IPC: B01L3/00
Filed: 1995-06-06
Abstract: Self-testing for a disease or physiological condition is achieved by having the individual being tested obtain a sample of physiological fluid, e.g., blood, mine, sputum or saliva, from him or herself. The sample is introduced into an assay system which produces a coded pattern indicative of the presence or a different coded pattern indicative of the absence of the disease or physiological condition. The individual then transmits the coded pattern to a remote location, for example by making a telephone call to an interpretation center, and receives from the remote location an interpretation of the coded pattern together with any counseling which may be appropriate in view of the interpretation of the coded pattern. The coded patterns are selected such that the individual may not interpret the test results without consulting the interpretation center. Further. the assay system, employed is advantageously made so that the coded patterns indicative of a positive or negative result are dependent on an identifier, such as a lot number or a serial number, assigned to the assay system or kit containing the assay system.

Title: Nematicidic agent and method for the bio-control of nematodes
Inventor: MENA CAMPOS JESUS
IPC: A01N63/20
Filed: 1995-08-10
Abstract: New bacterial strains, in particular Sphingobacterium spiritivorum C-926 and Corynobacterium paurometabolum C-924 with useful characteristics in the farming sector due to their nematicidic effect, which can be used in this context for the bio-control of nematodes. Bionematicides capable of effectively controlling phytopathogenic nematode populations in various crops of interest. Useful strains may be isolated from soil taken from areas habitually affected by a high incidence of nematodes, from banana plants showing less severe symptoms of infestation. Strains are selected which are capable of affecting the eggs of the nematode Meloidogyne incognita, in experiments carried out under laboratory conditions. Active strains, such as Sphingobacterium spiritivorum strain C-926 and Corynobacterium paurometabolum strain C-924, are tested to assess the protection which the bacterial preparation, applied directly, can provide to pumpkin and banana plants in relation to Meloidogyne incognita and Radopholus similis. Strains may also be tested against the zoonematodes Haemonchus sp. and Trichostrongylus sp.  Control of these parasites allows veterinary use. In addition to the nematodes referred to above, and selected due to the high losses which they incur in crops, the strains may also be effective in the control of populations of Heterodera ssp., Globodera ssp., and Pratylenchus ssp., as well as other species of zoonematodes.
