Abstract: The present invention provides a method of forming a pre-wrapped gift package which appears to have been hand wrapped. The method includes forming a sheet of box construction material with decorative paper affixed thereto into a box tube by joining ends thereof. The box construction material is properly creased and provided with flaps so that a consumer may fold the flattened box tube into a box so that the end flaps form ends of the box and the decorative paper forms a pair of paper flaps which may be overlapped and taped. A flattened pull bow is provided to form a gift wrapping kit with the flattened box tube which may be distributed and displayed in a flat package. A flattened, collapsed open box with the same volume as the pre-wrapped gift package is attached to the outside of the assembly in such a manner that a prospective purchaser may erect the open box and use it to determine whether or not the pre-wrapped gift package is the proper size for the gift the purchaser desires to be packaged.

Abstract: A method and apparatus of magnetic force control for a scanning probe, wherein a first magnetic source having a magnetic moment is provided on the scanning probe and a second magnetic source is disposed external to the scanning probe to apply a magnetic field in a direction other than parallel, and preferably perpendicular, to the orientation of the magnetic moment, from the second magnetic source to the first magnetic source to produce a torque related to the amplitude of the applied magnetic field acting on the probe. By controlling the amplitude of the applied magnetic field, the deflection of the scanning probe is maintained constant during scanning by the scanning probe. An output signal related to the amplitude of the magnetic field applied by the second magnetic source is produced and is indicative of a surface force applied to the probe. The invention can also be used to apply large forces during scanning for applications such as nanolithography or elasticity mapping.

Abstract: The striated muscle of the tongue of an animal (in particular, a mammal) is employed as the target tissue for direct DNA injection of an exogenous polynucleotide sequence encoding a biologically active molecule. The DNA is incorporated into the tongue muscle cells and the polypeptide encoded thereby expressed, resulting in the production of a biologically active molecule. Superior levels of expression of the injected exogenous polynucleotide are achieved relative to injection in other types of cells, in particular other types of muscle cells. Moreover, the striated muscle of the tongue represent an easily accessed anatomic location that has not previously been used for direct DNA injection.

Abstract: A combined scanning probe and scanning energy microscope, in which the same scanning system is used for both the scanning probe and scanning energy images. A sample is translated substantially along a horizontal plane either between or below the probe of a scanning probe microscope and the objective of a scanning energy microscope. The probe collects topographic or other information. The objective focuses a fixed beam of energy to a small spot on the sample, then collects energy from the same spot and transmits it to a detector. A vertical translator connected to the probe or sample support provides the vertical motion necessary to maintain them in close proximity. The images produced by the two microscopes are in substantial direct registration with each other. The invention is exemplified by a combined atomic force and confocal laser scanning microscope with a translated sample.

Abstract: A container for displaying and transporting a heavy product, such as a vanity top, is fabricated and assembled as an integral unit to secure the product against possible damage while permitting the product to be easily transported and viewed by prospective purchasers. Each of its pair of side wall panels has an elongated central flap section which is hinged and folded inwardly to define a generally front-facing double fold front surface for the container slanted in a front and back direction and elongated in a direction generally transverse to the top and bottom wall panels. An upper end flap hinged along an upper edge of each side wall panel is at least in part folded inwardly in spaced generally parallel relation to the side wall panel, defining a surface extending generally transverse to the top and bottom wall panels to block movement of the product toward the back panel. Central, upper and lower pairs of overlapping rounded tabs are cut in the side wall panels and in the intermediate flap sections.

Abstract: A radio link for a digital radio transmission system having spatial and/or angular diversity is optimized in real time by searching for a minimum of the analog BER function BERn(.phi.), by analyzing the minimum to determine if it is an "absolute" minimum that will result in an optimal radio link, and if not, searching for another minimum until the absolute minimum is located. Once the relative phase .phi. corresponding to the absolute minimum has been thus determined with both channels having the same nominal attenuation level, the relative attenuation level T of the two channels may then be varied in order to optimize the dispersion Ban.sub.n (T) of the recombined data spectrum while holding the relative phase at its previously optimized value.

Abstract: A container for a substance that is liquid, viscous, or semi-liquid, is provided with an applicator comprising a cap (22) having an outlet slot (32) in which an elastically deformable tongue (20) is engaged, the tongue extending one of the walls of the container and being capable of passing by elastic deformation from a rest position in which it closes the outlet slot (32) to a working position in which it opens a portion of the slot.

Abstract: Antenna elements and systems and other radio and microwave frequency devices are constructed with a high index of refraction medium having high matched values of relative permeability and relative permittivity, and a low loss tangent. By making the permeability of the transmission medium substantially equal to its relative permittivity, the impedance of the material is matched to that of the surrounding free space or air. By immersing a radiating element in such a material, and/or by using such a material between adjacent radiating elements or between a radiating element and a reflective ground plane, the physical size and/or the spacing of the elements may be substantially reduced without appreciable performance loss, thereby resulting in a more compact device that is particularly desirable for mobile applications.

Abstract: The disclosed spread spectrum system has the reference transmitted on one phase (basis vector) of a .pi./2-offset QPSK signal, and the spread data signal transmitted on another phase (basis vector). The two received phases are combined to recover the baseband signal. Such a transmission system is tolerant to multipath dispersion since all delay paths carry an appropriately delayed reference and signal path induced dispersion on the spread data signal is also present on the reference. If one of the two signals is delayed by a predetermined time interval and a corresponding delay is present in each of two cross-coupled signal processing paths following a conventional I-Q demodulator, the resulting two phase quadrature baseband signals may be combined to form a replica of the original baseband signal. The resultant asynchronous demodulation eliminates the usual requirement for carrier lock at the receiver and is therefore tolerant to Doppler shifts and other frequency errors.
