  • Patent number: 11916362
    Abstract: The present disclosure provides a cable tray fitting with tray connector and a flexible membrane with opposite longitudinal ends. The tray connectors are secured to the opposite longitudinal with each being secured to one of a pair of adjacent cable tray sections. The flexible membrane allows relative movement between the cable tray sections. The disclosure provides a cable tray assembly including first and second cable tray sections each with a longitudinal end. The cable tray assembly includes a cable tray fitting secured to and disposed between the longitudinal ends of the first and second cable tray sections. The disclosure provides a method of assembling a cable tray assembly by securing a cable tray fitting to opposing and adjacent longitudinal ends of first and second cable tray sections and allowing the cable tray sections to move in three dimensions relative to one another by virtue of the flexible membrane.

  • Patent number: 10197713
    Abstract: A light directing film includes a structured major surface with a plurality of microstructures extending along a first direction. Each microstructure has a first region and a second region different from the first region, a substantially constant height in the first region and a non-constant maximum height in the second region greater than the substantially constant height in the first region, and a same lateral cross sectional shape in the first region and the second region.

  • Publication number: 20110181971
    Abstract: An approach for making a master tool used to fabricate optical films involves cutting a series of base structures. Modifying features are superimposed with the base structures, producing abruptly discontinuous variations in the shape of the base structures. Diffraction elements may be formed in one or both of the base structures and the modifying features. The modifying features can be formed by moving the cutting tool in the x-direction, in the z-direction, or along a trajectory having both an x component and a z component.

  • Patent number: 5798921
    Abstract: An audio system is disclosed wherein music cartridges are utilized in a series of cartridge racks for non-mechanical playback and recordation of an entire music collection. The audio signals are stored on music cartridges which are insertable into one of a plurality of cartridge racks. The cartridge racks are operatively connected with the music player of the audio system. The audio system is completely solid state, i.e. it has no moving parts and has the advantages of allowing quick and reliable playback and storage of any music cartridge of the user's entire selection, as desired by the user. The system is self-programmable and expandable, whereby additional cartridge racks can be connected for additional storage of music cartridges allowing any music cartridge from the entire collection to be accessed at anytime.

  • Patent number: 4869497
    Abstract: A computer controlled exercise machine in which the user selects an exercise mode and its profile by programming the computer. Signals are produced by the program to control a resistive force producing device. Sensors produce data signals corresponding to the force applied to the actuating member of the system, velocity of movement and angular position which are continuously sampled at a high rate by a microprocessor operating under control of the program. The sampled data values are used to update and display performance results for the exercise and to compute the values of other parameters and, in some exercise modes, to control the amount of the resistive force.
