  • System for dynamically determining the size and number of communication buffers based on communication parameters at the beginning of the reception of message
    Patent number: 5916309
    Abstract: An improved communications buffer system is provided which dynamically allocates the size and number of buffers to optimally receive packets of communications data over a communications link, while efficiently using the amount of available memory so as to provide optimal throughput capability with respect to the allocated amount of memory. This buffer system is readily adaptable for infrared communications ports used on printers. Once a communications session has begun, the printer will obtain sufficient information to most effectively allocate the size and number of buffers. At the beginning of this procedure, the printer must first determine how much "free" memory is available in its "pool area" and then determine how best to divide up that pool area into both transmit and receive buffers. The size and number of transmit buffers is first determined, and this determination is made after considering how much pool area is available in the printer's memory system at that moment.

  • Bit map adjustment preserving resolution
    Patent number: 5650857
    Abstract: An electrophotographic printer (1) adjusts high resolution data while preserving the resolution capabilities of the printer. Data in a 600.times.600 bit map is assigned alternately to two rows of a 300.times.1200 bit map. Excellent visual effects are realized.

  • Alkoxylated quaternary ammonium surfactants
    Patent number: 4370272
    Abstract: Esters of alkoxylated long chain fatty alchols with halo acetic acid are contacted with tertiary amines incorporating a long chain aliphatic group to produce a class of novel quaternary ammonium compounds. These product compounds have utility as fabric softeners and as hair conditioners.
