  • Publication number: 20240147644
    Abstract: A foldable display device may have housing portions coupled by a hinge. A flexible display may overlap the hinge. The hinge may have portions that rotate relative to each other about rotational axes that lie above the hinge to help reduce stress to the display. The hinge may have gear plates with interlocked teeth that synchronize rotational movement between left and right halves of the hinge. The hinge may also have asymmetric friction clips that impose different amounts of rotational friction to the hinge depending on the direction of rotation of the hinge.

  • Patent number: 8931615
    Abstract: A roller bearing and newel guide assembly (30) for a newel (24) in an escalator (10) has a newel guide (32), a roller chain (34), and a spring (40) connected between the roller chain (34) and the newel guide (32) to provide tension to the roller chain (34). The roller chain (34) comprises a series of interlinked chain units (36). Each chain unit (36) includes a frame (78), at least one roller bearing (72), and a pin (76) for connecting the roller bearing (72) to the frame (78). Each chain unit (36) has a female connector (62) and a male connector (64), which allow each chain unit (36) to connect to an adjacent chain unit (36) to form the roller chain (34).

  • Publication number: 20140219289
    Abstract: A part of a non-default multitenant device context (MDC) is located on a member device of that forms part of a logical network device. The non-default MDC part assigns a first downlink port to a first downlink port group, assigns a first uplink port to a first uplink port group, and monitors a stacking port to another part of the non-default MDC on another member device that forms part of the logical network device. When the stacking port changes to the down state, the non-default MDC part determines if the first downlink port group and the first uplink port group are in the up state. If so, the non-default MDC part maintains the states of the ports in the first downlink port group and the first uplink port group. Otherwise the non-default MDC part makes changes so the ports in the first downlink port group and the first uplink port group are in the down state.

  • Patent number: 8757350
    Abstract: A connection between step flange covers 54 and passenger conveyor frames 60 is adjustable to vary the position of a step flange cover relative 54 to moving tread plates 18 or a moving skirt 52 in at least two directions. The adjustable connection 64 permits the step flange cover 54 to be precisely positioned with respect to the tread plates 18 or the skirt 52 without the necessity of using crude adjustment techniques, such as, for example, using shims.

  • Patent number: 8596445
    Abstract: A balustrade assembly includes a decking panel and a skirt panel that are attached to one another and to a balustrade support structure without fasteners. A positioning device included in the balustrade assembly varies the position of the skirt panel relative to moving steps in two directions by pushing against stationary components that are a part of or otherwise connected to a frame of a passenger conveyor. A balustrade support employed in the assembly reduces material and manufacturing costs and is adjustable to vary the height of a balustrade panel and handrails in a passenger conveyor.
