Abstract: The present invention relates to a system and method of exchanging information that can be specific to a person and their current location. The method uses the location of a wireless device held by a stakeholder, i.e. a person that is related to the information, and routes information to the zone they are in. The portable wireless device is used to track the location of the stakeholder, and also provides methods for updating relevant information while the stakeholder is located in a specific zone.

Abstract: The invention covers a robot cleaner that includes a cleaning unit and wheels to move the robot cleaner. The robot cleaner also includes a processor for controlling cleaning that is capable of estimating the size of a room based on distances between obstacles. The robot cleaner has several modes of operation that allow it to clean an entire room more effectively.

Abstract: A client for a text-based messaging application for a dual-mode mobile communication device may initiate an audio conference based on a text-based message. Contents of fields of the text-based message may be extracted and utilized to construct an audio conference request message that is subsequently transmitted to an audio conference gateway. Where the text-based messaging application is an instant messaging (IM) client application, it may be configured to recognize a voice connection as being related to an ongoing Data Mode IM conversation. As a consequence of the recognition, the IM client application may maintain the user interface for facilitating participation in the Voice Mode IM conversation. Updates related to the status of the Voice Mode IM conversation may be received at the dual-mode mobile communication device over the voice connection and reflected in changes to the user interface.

Abstract: The invention pertains to a robot cleaning system that includes a robotic cleaner having a tactile sensor and a barrier unit, wherein the barrier unit is such that the tactile sensor on the robot cleaner is triggered by contact with the barrier unit. As a result the robot changes directions. The barrier unit can be adapted to avoid sliding, such as when the robot comes into contact with it. The anti-slide element can be projections such as hooks or rubber grommets and the like.

Abstract: A method and apparatus for searching an electronically stored table of information including a plurality of table entries and facilitating high speed searching of a table to provide a longest matching entry. The table searching method uses at least one memory unit having a table of information including a plurality of data entries. The table of information has a plurality of search keys associated with the plurality of data entries and the plurality of search keys form a tree structure based on a prefix length for each of the search keys. The plurality of search keys are expanded such that each of the plurality of search keys has two lowest level search keys associated therewith that cover a lowest level of the tree structure. A binary search of the lowest level search keys is performed based on a search value to determine a longest prefix match. A data entry of the plurality of data entries is output based on said longest prefix match.

Abstract: A robot uses an infrared sensor including an infrared light source which produces pulses of infrared light. Optics focus reflections of the infrared light pulses from different portions of the environment of the robot to different detectors in a 2D array of detectors. The detectors produce an indication of the distance to the closest object in an associated portion of the environment. The robot can use the indications to determine features in the environment. The robot can be controlled to avoid these features.
