  • Patent number: 11719313
    Abstract: An actuator assembly for actuating air blocking elements of an outlet assembly is provided. The actuator assembly includes an actuator arm and a selector member operatively connected to the actuator arm to rotate the actuator arm about an arm axis. The actuator arm is operatively connected to a first air blocking element to rotate the first air blocking element towards its air blocking position without moving a second air blocking element upon rotation of the actuator arm in a first direction from a neutral, non-blocking position of the actuator arm about the arm axis. The actuator arm is operatively connected to the second air blocking element to rotate the second air blocking element towards its air blocking position without moving the first air blocking element upon rotation of the actuator arm in a second direction opposite the first direction from the neutral, non-blocking position.

  • Patent number: 11685236
    Abstract: An outlet assembly having a plurality of different operating modes for improving air flow in an air distribution system is provided. The assembly includes a first blocking element supported by a first wall of a housing for movement between blocking and unblocking positions within a cavity of the housing. The first blocking element prevents a first layer of air from flowing immediately adjacent the first wall in its blocking position. A second blocking element is supported by a second wall of the housing for movement between blocking and unblocking positions within the cavity. The second blocking element prevents a second layer of air from flowing immediately adjacent the second wall in its blocking position. An actuator subassembly including a selector member is supported for movement between a plurality of predefined positions which correspond to first and second blocking modes and a nominal unblocking mode.

  • Publication number: 20080103451
    Abstract: The present invention includes methods, kits and bandages that accommodate a medical device extending from an incision in a patient. The bandage includes an outer surface, inner absorbent layer and one or more closure mechanisms. The outer surface includes a slit extending from an outer peripheral edge to an inner peripheral edge that forms an aperture to accommodate a medical device. The inner absorbent layer is in contact with the outer surface and at least partially spans the aperture to accommodate the medical device. The one or more closure mechanisms are used to substantially seal the slit. The bandage is positioned about the incision and secured about the medical device for absorption.

  • Publication number: 20050239518
    Abstract: The present invention manages power for state machines. The system and methods selectively apply, remove and/or reduce power to portions of the state machine, based on power management schemes, intelligence, a user, an application, etc. Such novel systems and methods provide for sustaining a CPU and/or a network radio in an “on” state, while lowering and/or removing power to other portions of the state machine to reduce power consumption. The foregoing enables a wireless mobile terminal to maintain network connectivity and be able to wake to service events such as a link status change, a network keep alive, a proxy-ARP packets, a re-authentication packets, etc. Such power management can execute in the background and return the wireless mobile terminal to a “run” state via invocation from a wake source such as a power control, a key, a trigger, a touch screen, a wake up timer, a wake-on-LAN, etc.
