  • Patent number: 11961401
    Abstract: An example operation may include one or more of detecting a potential event via sensors on a transport, sending data related to the potential event to other transports within a predefined distance, storing the data at the transports and a server, and performing a transport operation response on the transports.

  • Patent number: 5812569
    Abstract: The energy of a series of output pulses of a solid state laser pumped by a diode array and triggered by a Q-switch is stabilized and rendered independent of the repetition rate by interrupting the pumping to allow the energy stored in the laser active element to fall at the commencement of an interval between a pair of Q-switch trigger signals that is longer than the interval corresponding to the chosen repetition rate. Before the second of this pair of Q-switch trigger signals occurs, the pumping is recommenced for a duration and at an input level that restore the stored energy to the value required for generating output pulses of the laser at the desired energy level.

  • Patent number: 5400351
    Abstract: To maintain substantially constant the temperature of a diode junction of a pulsed, cooled, diode laser and hence the wavelength of the optical output of the laser, which laser is used for optically pumping a main, pulsed, solid state laser, the diode junction is heated by an external source during inactive intervals between pulses of the diode laser. This heating, which preferably is achieved by passing a heating current through the diode junction, is adjusted to ensure that, per a unit time greater than the length of an inactive interval, the heat energy received by the diode junction from this external heating together with the heat energy generated in the diode junction itself by the pulses is substantially constant independent of the length of the inactive intervals. Preferably the heating current has a constant level except for a period after each pulse when the level is reduced, e.g. to zero.

  • Patent number: 4661548
    Abstract: An aqueous copolymer emulsion useful as a ceramic tile adhesive contains filler material, a zinc compound and an aqueous emulsion of a copolymer containing residues of an unsaturated aliphatic hydrocarbon monomer, an unsaturated monomer copolymerizable therewith and a small amount of residues containing carboxyl groups.

    Inventor: Robert G. Parker
  • Patent number: 4339370
    Abstract: Highly filled crosslinkable emulsion polymer compositions containing vinyl aromatic monomers and acrylate or methacrylate monomers can be provided with improved retention of adhesive power in the face of attack by water and improved shelf-life by the presence of zinc ammonium carbonate in the composition. The zinc ammonium carbonate is preferably in the form of an aqueous solution prepared by reacting an equimolar amount of ammonium carbonate and ammonium hydrogen carbonate with zinc oxide and ammonia.
