  • Patent number: 11455701
    Abstract: Computer-implemented functionality is described herein for assisting a user in interacting with an environment. In one implementation, the functionality operates by: determining that a particular user is within a prescribed proximity to an electronic sign, or will be in prescribed proximity to the electronic sign, based on sensor information provided by one or more sensors within the environment; determining an identity of the user; determining at least one destination of the user based at least on calendar information; providing directions to the destination(s), to provide unfiltered direction information; optionally filtering the unfiltered direction information with respect to restriction information (e.g., privacy information, security information, etc.), to produce filtered direction information; composing sign information based on the filtered direction information; and sending the sign information to the electronic sign for presentation by the sign.

  • Patent number: 5033412
    Abstract: An apparatus for the semi-automatic feeding of piglets up to 21 days old, comprises an open feeding trough which is supplied with liquid feed in predetermined quantities at predetermined intervals. The inlet to the feed trough is disposed substantially centrally along the length of the trough, in the vicinity of a raised area of the trough, so that the feed distributes itself to the end of the trough under gravity. The strong, dominant animal of the group automatically makes to feed from the trough vicinity of the feed inlet, and the sloping arrangement of the trough ensures that the smaller, weaker animals obtain an adequate supply of feed. The trough surface is smooth and essentially free from crevices, recesses and the like, so that it is essentially cleaned by the feeding piglets themselves.

  • Patent number: 4485179
    Abstract: A silicon carbide fiber reinforced glass-ceramic matrix composite is disclosed having high strength, fracture toughness, and improved oxidative stability even at high temperature use, e.g., in excess of 1000.degree. C. The composite is made up of a plurality of glass-ceramic layers, each layer reinforced with a plurality of unidirectional continuous length silicon carbide or discontinuous SiC fibers. The composite is formed by starting with the matrix material (preferably lithium aluminosilicate) in the glassy state and converting it from the glassy state to the crystalline state after densification of the composite. Ta or Nb compounds are added to the matrix composition prior to consolidation to form a reaction or diffusion barrier around the SiC fiber, resulting in composites with high temperature oxidation stability. Substitution of at least part of the Li.sub.2 O in the matrix with MgO results in an even higher temperature stable composite, e.g., up to about 1200.degree. C.
