Abstract: The acoustic shutter assembly (1) includes at least one window pane (2, 3) arranged in a frame (4). At least one ventilation duct (7) is arranged in the frame between an outer ventilation opening (8) and an inner ventilation opening (9), extending between a first layer of sound absorbing material arranged at an inside (5) and a second layer of sound absorbing material arranged at an outside. A number of acoustic reflectors (12) in the form of plate material are arranged between the first and second layers of sound absorbing material so that the ventilation duct is separated into a number of respective ventilation channels (13) formed between the acoustic reflectors. Each ventilation channel changes direction at least once between the outer ventilation opening and the inner ventilation opening, thereby at least substantially blocking any linear path from the outer ventilation opening to the inner ventilation opening.

Abstract: A greeting card having an audio message and playback device delivers a first sound recording upon opening of the greeting card and a second sound recording upon closing of the greeting card. The delivery of each sound recording may be delayed by a timing component within the audio message and playback device. Additionally, the delivery of each sound recording may be played simultaneously or in queue. Sound recordings may also be recorded by a user using a recording component that is in addition to the audio message and playback device. The audio message and playback device may also include an additional trial mode component that allows the user to test a recorded message before purchasing the greeting card and place the greeting card into a use mode that allows the user to permanently record the message.

Abstract: The invention generally relates to ventilation systems and methods, and more particularly to selectively configurable climate control systems and methods for use in data centers and the like. A system includes a first structural element and a second structural element spaced apart from first structural element to define a space between the first and second structural elements. The system also includes a plurality of partitions moveable into the space between the first and second structural elements and a controller arranged to control movement of the plurality of partitions.

Abstract: A canopy assembly for sheltering a drive-up ordering station of a fast food restaurant can pivot out of the way when impacted by a vehicle and return automatically to a centered position. A centering feature mounted to a column supporting a roof structure engages a pivotal coupler to bias the roof to a center position. This feature includes a pivot post assembly extending across the cavity and through a pair of helical slots in the coupler. When a leading end of the roof assembly is struck by a vehicle, the coupler is rotated and the pivot post engages the slots so that the coupler translates upward. The coupler is biased by gravity to a centered position in which the top ends of the slots rest on the pivot post.

Abstract: The conversion unit is a simple frame structure applied inwardly of a window opening, such as in a residential basement equipped with metal casement windows. It comprises a pair of like triangular end members or panels bridged across inner upright edges thereof by a light-transmitting portion in which a pair of ornamentally decorated sliding panels are mounted, as in a pair of overlapped grooves in a frame part of the panel portion. The unit is applied with outer vertical edges thereof in abutted engagement with a wall carrying the casement window and with upper margins of the generally triangular open frame structure in upwardly flush engaging abutment with the room ceiling just above the casement window zone. the sliding panels are chosen of a decorative plastic, semi-rigid sheet, preferably somewhat flexible in nature, and also by preference provision is made for a removal of the unit from the casement area for full access to the castment window from its interior.
