Assignee:

Aero-Design Technology - Valencia CA

International Classification:

B30B 1506

US Classification:

100 48

Abstract:

A trash collection and compacting apparatus primarily intended for use onboard an aircraft comprising a stationary compactor unit and interrelated movable wheeled trolley unit, the trolley unit having a plurality of separate trash collection chambers into which trash is deposited and compacted and support rails for supporting the trolley unit on the compactor unit for the direct compaction of trash in the trolley. The trolley unit also has separable sides to facilitate removal of compacted trash, and multiple fail safe locks and latches to ensure that the sides are not inadvertently separated during trash collection and compaction. Fire doors are provided to close the chambers, and removable trash bins are disposed in each trash chamber to facilitate handling of compacted trash, the bins having separable sides for emptying the compacted trash therefrom. The compactor unit includes a compaction ram mounted on a carriage assembly for movement into discrete positions overlying each collection chamber of the trolley unit and supports the trolley so that compaction forces are not transmitted to the aircraft.

International Classification:

US Classification:

100 50

Abstract:

A trash collection and compacting apparatus primarily intended for use onboard an aircraft comprising a stationary compactor unit and interrelated movable trolley unit, the trolley unit having a plurality of separate trash collection chambers into which trash is deposited and compacted. The trolley unit includes wheels for moving the trolley through an aircraft for the collection of trash, and support rails for supporting the trolley unit on the compactor unit for the direct compaction of trash in the trolley. The compactor unit includes a compaction ram mounted on a carriage assembly for movement into discrete positions overlying each collection chamber of the trolley unit, and supports the trolley so that compaction forces are not transmitted to the aircraft. The trolley unit includes separable sides and dividing panels which facilitate the removal of compacted trash within the chambers, and has multiple fail safe locks and latches to ensure that the sides and panels are not inadvertently separated during trash collection and compaction. The trolley unit is also provided with fire doors to close the chambers, and removable trash bins are disposed in each trash chamber to facilitate handling of compacted trash, the bins having separable sides for emptying the compacted trash therefrom.

Filed:

Appl. No.:

8/944199

Inventors:

Mark A. Mathews - San Jose CA

International Classification:

G06K 936

US Classification:

382246

Abstract:

System and method using a competitive process to create an optimized set of variable length bit codes to encode one, two or three dimensional data and a high speed redundant lookup table for decoding the resulting representation in real time. The encoding phase consists of multiple passes through the unencoded data to determine the overall best code set for the given data. The primitives used to encode the data may be any mix of operations that captures the redundancy of the raw data. For graphic applications, specific colors and patterns copied from previously occurring data yield sufficiently high compression ratios, but any likely candidates for high frequency occurrence may be added to the mix. The encoding algorithm will ignore any non-optimal operations and assign them no space in the code set. The decoding phase takes the code set generated by the encoding phase and builds one or more redundant lookup tables, where each code's entry occurs a sufficient number of times to guarantee that a single lookup using the next n bits of the encoded data stream as index will correctly decode the next code in the stream.

F21V 21/14
F21V 23/04
H05B 37/02

Abstract:

The present disclosure describes a control scheme for actively detecting the presence of a pedestrian which triggers the lighting of a bollard-style luminaire, methods for crosswalk illumination using the bollard-style luminaires, and methods of communication between bollard-style luminaires. The present disclosure further describes actively monitoring for vehicles and indicating safe passage, through lighting feedback on a pedestrian crosswalk or other walkway. The bollard luminaire includes a design that generally confines light to illuminate the crosswalk and the pedestrian in the crosswalk, such that light that could produce glare for the pedestrian and/or a driver approaching the crosswalk is minimized.

Abstract:

The present disclosure describes light delivery and distribution components of a light duct that can be used as a luminaire, such as a bollard-style luminaire that can be useful for the illumination of pedestrian crosswalks, the light engine useful in the luminaire, and methods for making the light engine and the luminaire. The present disclosure further describes methods for crosswalk illumination using the bollard-style luminaires, and methods of communication between bollard luminaires. The bollard luminaire includes a design that generally confines light to illuminate the crosswalk and the pedestrian in the crosswalk, such that light that could produce glare for the pedestrian and/or a driver approaching the crosswalk is minimized.
