Abstract: A concise linked document language, a computer network client interpreting the concise linked document language, and exemplary applications using the concise linked document language. The concise linked document language incorporates features which allow presentation, acquisition, and document links using a distributed client composed of a computer network device linked via a communications link to an information device. The distributed client can be used to access servers located on a computer network from almost any information device creating a pervasive computer networking environment. The features of the concise linked document language allow rapid construction and deployment of Internet based applications which are extended by existing communications links such as a voice/email system where the native email documents may be presented as either text or voice depending on the presentation capabilities of the information device.

Abstract: The present invention provides a pneumatically operable indication of when a pretensioner has operated in a vehicle passenger safety restraint system. The indication may be audible or visible, for example an inflatable brightly coloured balloon in the vehicle trim or a whistle or a flag. Such an indication ensures that the vehicle owner knows when the pretensioner feature of his vehicle is not available for a subsequent crash condition so that he can seek re-setting or servicing of the pretensioner at the earliest opportunity.

Abstract: A multilamp photoflash unit including an elongated plastic housing having a longitudinal channel therein. Within the channel is positioned a thin, flat circuit board to which are connected several (e.g. six) flashlamps arranged in a linear array. The lamps are divided into two opposing pluralities such that those in the plurality being fired are inverted during firing.

Abstract: A photoflash unit comprising a plurality of high voltage type flashlamps mounted on a printed circuit board containing circuitry for sequentially igniting the flashlamps. A plurality of electrically conductive reflectors respectively associated with the flashlamps are disposed between the lamps and the circuit board, with each reflector having an aperture in alignment with a corresponding aperture in the circuit board. Connected in series with each but the last lamp of the array is a radiant-energy-activated disconnect switch comprising a strip of electrically conductive heat-shrinkable polymeric material which is attached at both ends to the circuit board so that the midportion of the strip bridges a respective one of the apertures therein. A sheet of electrically insulating material is interposed between the reflectors and circuit board to prevent shorting therebetween. A plurality of deformations, such as dimples, are formed in the insulating sheet for spacing the sheet from the disconnect switch strips.

Abstract: A photoflash unit comprising two parallel columns of horizontally disposed lamps mounted in a planar array with flash indicators aligned behind each lamp. The lamps of one column are staggered with respect to the other, and the two columns are located on opposite sides of the vertical centerline of the unit. The lamps are connected to switching circuitry for sequentially flashing the lamps in response to firing pulses applied to a connector at one end of the unit. The two columns of staggered lamps are positioned so that the lowest lamp is located on the side of the unit centerline opposite that on which the lens axis is located when the unit is connected to a camera, thereby farther removing the closest lamp from the lens axis to minimize the "red-eye" effect. The switching circuitry is connected to provide an order of flashing that proceeds alternately between the two columns from the lowest to the highest lamp of the array, thereby providing a more readily interpretable flash indicator pattern.

Abstract: A photoflash lamp-reflector module for use in a photoflash unit having a plurality of such lamp-reflector modules arranged in a compact array. Each reflector has a substantially parabolic surface with a centrally disposed elongated cylindrical recess having a longitudinally extending central slot. The associated tubular lamp is nested within the recessed portion of the reflector, whereby an oversized lamp is accommodated by the reflector with little or no loss of light output.

Abstract: A photoflash unit comprising a plurality of high-voltage type flashlamps mounted on a printed circuit board containing circuitry for sequentially igniting the flashlamps in response to successive high-voltage firing pulses applied thereto. One lead-in wire of each of the flashlamps is connected to a common circuit conductor. Electrostatic protection is provided by a conductive array of reflectors positioned between the lamps and one side of the circuit board and a planar shield of conductive material disposed parallel to and spaced from the opposite side of the circuit board, both the reflector array and shield being electrically connected to the common circuit conductor and thereby effecting a static "grounding" system. The assembly is enclosed in a plastic housing having a light-transmitting side wall adjacent to the flashlamps.

The primer may bridge the wire terminations or comprise separate spaced apart coatings on the respective terminations, with the filamentary combustible being in contact with both terminations to provide a conducting path therebetween. The frit coating is thick enough to prevent preignition short circuits.

The lead-in wires are composed of an iron-nickel-cobalt alloy. The intermediate expansion glass may be in the form of a bead having its midportion between the lead-in wires stretched to protrude toward the filament to prevent post-ignition short circuits.

Abstract: A photoflash lamp having an hermetically sealed envelope containing a pair of lead-in wires spaced apart by a glass bead and having a glass insulator sleeve located about one of the lead-in wires between the bead and the inner end of the wire. A moisture indicating material is coated on portions of the lead-in wires and the glass sleeve for indicating by a change in coloration the presence of air contamination within the envelope and for insulating the lead-in wires to prevent pre-ignition short circuits through filamentary combustible material located within the envelope. The indicating material comprises a mixture of cobaltous cobalticyanide and colloidal magnesium silicate, which composition tends to minimize pressure build up during flashing.
