  • Patent number: 11978575
    Abstract: Power umbilical (1) comprising a plurality of power cables (7) for electric power transmission, elongated filler elements (5), and an outer sheath (3). The elongated filler elements (5) abut against each other at abutment faces (5a), thereby forming a complete ring enclosing the power cables (7). The elongated filler elements (5) comprise cable recesses (5b) within which the power cables (7) are embedded. The power umbilical (1) further comprises one or more friction control profiles (13, 15, 116), wherein the material of the friction control profile (13, 15, 116) is softer than the material of the elongated filler elements (5). The one or more friction control profiles (13, 15) are arranged in a deformed state.

  • Publication number: 20240147006
    Abstract: Methods, apparatus, systems, and articles of manufacture are disclosed to determine whether audience measurement meters are co-located. An example apparatus is to, based on a difference between a first sampling time of a first entry of a first log and a second sampling time of a corresponding entry of a second log satisfying a first threshold, determine at least one matching instance of at least one first device identifier of the first entry and at least one second device identifier of the corresponding entry. Additionally, the example apparatus is to populate a variable with the at least one matching instance. The example apparatus is also to, based on a metric satisfying a second threshold, cause transmission of an alert indicating that a first meter and a second meter were co-located during generation of the first log and the second log, the metric based on the at least one matching instance.

  • Publication number: 20240094120
    Abstract: This invention relates to the preparation of N-(phosphonomethyl)glycine (“glyphosate”) from N-(phosphonomethyl)iminodiacetic acid (“PMIDA”), and more particularly to methods for control of the conversion of PMIDA, for the identification of reaction end points relating to PMIDA conversion and the preparation of glyphosate products having controlled PMIDA content.

  • Publication number: 20090233737
    Abstract: The Batter's Box device is an instruction tool to help children, primarily but not limited to ages 5-12, learn two aspects of proper hitting mechanics for baseball and softball: 1) feet placement base, and 2) stride. Stride has two components, length and direction. The batter's box teaches feet placement and stride by limiting the movement of the batter's feet. The batter's box is a rectangular frame that is placed on the ground. The batter stands in the frame of the batter's box and two bungee cords, one attached to the frame in front of the back foot and one attached to the frame in front of the lead, or stride, foot, create a barrier that will constrain the batter's feet (the back foot and the stride foot) if they move with improper technique. The batter's box is adjustable for player's of different height and size. The frame may be widened and the restrictive bungee cords can be placed at various increments to complement longer or shorter legs.
