    Abstract: A spray application system for applying material to a surface of a rotating body such as a beverage can includes a detector that detects the actual speed of rotation of the surface during a spraying operation. This allows a controller to adjust trigger signals for the application device to be adjusted based on speed of rotation to minimize overcoat. A laser sensor may be used as an example. The use of the speed detector also allows for partial wraps as well as full wraps of applying material to the rotating surface.

    Abstract: A wireless communication unit (120) polls (200) a radio access point (110) at a certain frequency. The wireless communication unit (120) then determines (210) whether packets are received in response to the polling and determines (220) the percentage of polls resulting in receipt of packets. The wireless communication unit (120) then adjusts (230) the polling frequency to change the number of polls which result in the receipt of packets. Optionally, the wireless communication unit (120) repolls (240) the radio access point (110) when a packet in not received. Then, the wireless communication unit (120) plays (250) the packet at a certain time. Alternatively, the wireless communication unit (120) receives (310) packets without polling and determines (220) a radion access point frequency at which packets arrive at the radio access point (110). The polling frequency is then set (330) to approximately the radio access point frequency.

    Abstract: In an induction heater, preheated, pressurized air is further heated in the heating cabinet and also drawn into the coil tube via a suction fan. The simultaneous pulling and pushing of the twice-heated air through the tube provides superior air flow to pick up more moisture from the can ends being dried. The tube ends rest on upwardly concave collars and are held in place by gravity, with a single screw acting as a stop above to prevent upward movement. Removal requires only removing the single screw at each end then lifting the tube straight up out of the cabinet, which is facilitated by providing a hinged cover on the cabinet.

    Abstract: A holding member provides for releasably positioning a rotating control head assembly in a subsea housing. The holding member engages an internal formation in the subsea housing to resist movement of the rotating control head assembly relative to the subsea housing. The rotating control head assembly is sealed with the subsea housing when the holding member engages the internal formation. An extendible portion of the holding member assembly extrudes an elastomer between an upper portion and a lower portion of the internal housing to seal the rotating control head assembly with the subsea housing. Pressure relief mechanisms release excess pressure in the subsea housing and a pressure compensation mechanism pressurize bearings in the bearing assembly at a predetermined pressure.

    Abstract: A diagramming tool is provided that allows a diagram to be defined as a specialization of a “parent” diagram. The “child” diagram is defined based on the “parent” diagram such that the child diagram references the parent and contains only nodes and edges which represent differences between the instant diagram and its parent diagram. A diagram inherits all of the nodes and edges, and their properties, of its parent and adds, deletes, or redefines the nodes and/or edges that represent the differences or specializations.

    Abstract: A mobile station (106) establishes a real time communication link via an access point (102) for carrying voice or other time-sensitive data. A WLAN subsystem (204) of the mobile station is normally kept in a low power state. Upon initiating a communication link the mobile station signals to the access point that unscheduled power save delivery mode will be used (614), and the access point reserves resources to assure the necessary quality of service. The mobile station initiates a frame transaction by first powering up the WLAN subsystem (712), acquiring the WLAN channel (407), and transmitting a polling frame. Upon successful receipt of the polling frame the access point prepares to reply with an aggregate response. The aggregate response commences by transmitting all data in an aggregate buffer, including both reserved and unreserved data buffers. Upon successful receipt of the aggregate response, the mobile station places the WLAN subsystem back into a low power state.
