  • Patent number: 7072630
    Abstract: A method and apparatus for determining the data rate of a reverse link communication of an access terminal includes receiving a reverse activity bit (RAB) from an access point in the communication system, and passing the RAB to a digital filter to produce a filtered RAB. In one embodiment, the reverse link data rate is determined based on the filtered value of the RAB. Furthermore, a processor in the access terminal may determine whether the access terminal is in an idle mode, and passing a non-busy state value of the RAB to the digital filter when the access terminal is in the idle mode. The filtered RAB may be compared to a threshold to determine a mode of reverse link data rate determination. The mode defines a set of criteria for an aggressiveness level of increasing or decreasing the reverse link communication data rate. The processor, therefore, determines the data rate based on the filtered reverse activity bit in accordance with the determined mode.

    Abstract: A spray booth has an enclosure structure, a ventilation system and overhead lighting. An upper region of the structure defines an air inlet plenum. Air exits the inlet plenum into the work area of the booth through an array of filter elements. The resistance to airflow of the filter elements may be tuned to encourage non-uniform airflow in the workspace, and, in particular, to create a proportionately large inflow in a central region, and a flow near the walls. Part of the inflow may be located outboard of the overhead lighting assemblies, and part of the inflow may be located inboard of the lighting assemblies. The overhead lighting assemblies may be spaced apart by a distance that may be greater than the width of objects to be coated in the spray booth, and the lighting assemblies may be canted inward at an oblique angle relative to the horizontal, such that the wash of light from the spaced apart light sources may tend to be convergent.

    Abstract: A booth for coating objects with powder, in particular for powder painting, comprises in a manner known per se a housing, in which there is situated at least one application device, with which powder can be applied to the objects. Situated in the upper region of the housing is an air plenum, which is fed with supply air via an inlet opening. The air plenum is closed off downwardly by a filter ceiling. In contrast to known filter ceilings, the one according to the invention is air-permeable in its marginal region only, while in its central region it consists of air-impermeable material. The supply air is thus introduced into the interior of the booth as a kind of “air curtain” which flows mainly along the side walls of the housing of the booth, entrains in the process stray excess powder which has not adhered to the objects to be coated, and supplies it to at least one extraction opening situated in the bottom of the booth.

  • Patent number: 5912184
    Abstract: An enclosure provided with an air supply system, an exhaust system, and controls for manipulating the flow, temperature, dewpoint and relative humidity of the air within the enclosure are disclosed. The present invention aims to achieve with these components a system for containing chemical contaminants created during processing of silicon wafers during the chemical/mechanical, polishing/planarization processes involved in creating those wafers. The system prevents drying of the slurry used to process wafers by controlling the relative humidity within the enclosure via a humidifier, sensors and a controller that dynamically reacts to changes within the enclosure atmosphere. Preventing slurry drying is critical to maintaining high wafer throughput by reducing gouging and scraping of wafers and also by reducing equipment down time needed to clean dried slurry.
