  • Patent number: 10966474
    Abstract: A pair of gloves for removing calluses and dry skin including a first glove (11) having an abrasive surface of 100 to 150 grit (7) on at least one finger portion (3) of the glove for removing calluses and dead skin from the heel and other parts of the foot, hand, elbow and knees; and a second glove (12) having an abrasive surface of 200 to 250 grit (8) on at least one finger portion (3) of the glove to remove excess dead skin and to smooth/polish the heel and other parts of the foot, hand, elbow and knees; wherein both gloves have an abrasive surface of 220 to 320 grit on the palm/heel portion (4) of the glove for further polish and smoothing.

  • Patent number: 7720604
    Abstract: A satellite constellation optimized for stationkeeping fuel consumption is provided. The satellite constellation includes a plurality of satellites, each satellite having a corresponding inclined elliptical orbit, each orbit having an initial right ascension of ascending node (“RAAN”) value, a RAAN drift rate, a semi-major axis, an eccentricity, an argument of perigee and an inclination. Each satellite has a fuel consumption value required to maintain the RAAN drift rate, the semi-major axis, the eccentricity, the argument of perigee and the inclination of the corresponding orbit. The initial RAAN value and the RAAN drift rate for each orbit correspond to a minimized fuel consumption value for the satellite having the highest fuel consumption value.
