Abstract: A paint spray booth is provided containing a plenum packed with a contact material for treatment of paint overspray generated during operation of the paint spray booth. The contact material is packed to provide a relatively large surface area and a relatively large interstitial area defined by the contact material. As paint overspray and bulk fluid is drained and channeled through the plenum, contact efficiency between the bulk fluid and the overspray is maximized. Paint overspray is thereby effectively detackified.

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 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.
