Title: System and method for recording an image
Inventor: YOSEFI HANAN
IPC: H04N1/58
Filed: 2000-10-04
Abstract: A two-stage method for recording a quality enhanced image on a substrate has a preparation and a production stage. In the preparation stage, the digital image file is scanned for adjacent color pairs with different color values. This exhaustive list is processed according to pre-determined criteria per type of output device, creating a sub-list of color pairs that might potentially create artifacts on the recorded image. Several such sub-lists may be created, each per potential output technology to be used. Each sub-list of color pairs is accompanied by modification parameters, indicating the action that needs to be taken in the recording stage, in order to avoid the artifacts and thereby enhance the recorded image quality. In the second, Production stage, this enhancement information, prepared for the actual output device to be used, is used to modify the imaging parameters such as screening parameters, taking into consideration production information such as enlargement.

Abstract: Ready to hang ceiling fans that do not require any assembly from the shipping box. A first embodiment has foldable mounting arms for each of the fan blades so that an installer takes both the motor and pre-attached blades out of a shipping box and allows the folded arms to unfold when the ceiling fan is being mounted.  Another embodiment has foldable blades pre-attached to mounting arms that are attached to a motor housing. An installer simply takes both the motor and pre-attached folded blades out of a shipping box and allows the folded blades to unfold when the ceiling fan is being mounted.

Patent CA-2346715-A1 (CA)
Inventor: KULLANDER JAN
IPC: H04L47/22
Filed: 1999-08-27
Abstract: The present invention relates to a method and a system for communicating data packets over a packet switched network (325) and at least one access link (310, 345). A buffering network entity (320, 335) acts as the end-receiver of the transmitted data packets from the sending host's point-of-view. The buffering network entity (320, 335) feeds back to the sending host a status message, which in case of a lost or erroneously received data packet indicates where this degeneration of data has occurred, i.e. in the packetswitched network or over the access link. The sending host regularly checks the returned status messages and data flow algorithms are only triggered if a data packet has been lost or degenerated in the packet switched network (325). The invention thus prevents data flow algorithms such as slow start and congestion avoidance algorithms from being activated in the substantially error-immune packet switched network when data packets are lost in comparatively error-prone access links. This significantly increases the efficiency of the overall system.
