  • Patent number: 11963324
    Abstract: Electronic equipment may include structured fabric. Structured fabric may be used as a protective case or cosmetic cover for an electronic device, may be used to form a band that holds an electronic device against a user's body, or may be used to cover one or more openings in an electronic device. Structured fabrics may be soft and pliable while maintaining the ability to hold a given shape without added support. Structured fabric may be formed by laminating fabric such as warp-knit fabric with a stiffener such as polymer film. Structured fabrics may include openings through which signals such as optical or audio signals pass. To maintain the geometry and shape of the openings in the structured fabric without covering the openings, the stiffener and adhesive that are attached to the fabric may be cut to form a pattern of openings that align with the openings in the fabric.

  • Patent number: 4152970
    Abstract: A fluid pressure supply apparatus includes a fluid pressure source, a fluid supply circuit to receive fluid under pressure from the fluid pressure source, and a fluid return circuit. These circuits are to be coupled to an hydraulic motor through first and second fluid paths. The supply apparatus further includes first means to couple the fluid supply circuit to the first fluid path to cause the hydraulic motor to be operated by the fluid pressure in a predetermined sense, and second means simultaneously to couple the second fluid path either to the fluid supply circuit, to provide a regenerative coupling for the motor, or to a fluid return path. This latter coupling is initially to the second fluid path, the second means being arranged to transfer that coupling from the fluid supply circuit to the fluid return path during operation of the motor in the predetermined sense.
