Abstract: In order to satisfy a conventional demand from users for easily portable chairs that can be used in a variety of situations, a chair includes: a main body having a seat surface and capable of being installed on an installation plane; and a backrest rotatably attached to the main body. The chair is configured to have a box-like shape having one or more faces that are positioned so as to cover two lateral sides and an upper side of the seat surface in a folded state in which the backrest covers the upper side of the seat surface. The one or more faces are constituted by outer surfaces of the main body and an outer surface of the backrest. This chair can be easily carried to various places.

Abstract: A method for controlling an electric motor is described herein. The method comprises setting a current limit, a speed limit and a torque limit. The method also comprises sensing a DC link current, comparing the sensed DC link current with the current limit and adjusting the torque limit based on the comparison with the current limit to provide an adjusted torque limit. The method also comprises sensing the speed of the electric motor, comparing the speed with the speed limit and further adjusting the adjusted torque limit based on the comparison with the speed limit.

Abstract: A method is provided in which a call agent process that supports one or more Internet Protocol (IP) calls, stores to persistent memory a set of data associated with the one or more IP calls. An outage is detected affecting the one or more IP calls. Using the data retrieved from the persistent memory, the one or more IP calls are resynthesized using a device simulator process to simulate connectivity with endpoints that were participating in the one or more IP calls prior to the outage. After resynthesizing, depending on activity detected from devices associated with the one or more IP calls, the one or more IP calls are internally re-stitched/re-establishing (without signaling to endpoints) with the endpoints involved in the one or more IP calls, or the one or more calls are fully re-stitched/re-established by signaling an endpoint that was participating in the one or more IP calls.

Abstract: In one embodiment, a method for unifying rosters is provided. A client receives an escalation request associated with a first roster and responds to the escalation request. The client subscribes to the first roster as a participant in response to accepting the escalation request or subscribes to the first roster as an observer in response to denying the escalation request. The client identifies a second roster within the first roster that the client is not subscribed to and subscribes to the first roster as an observer. The client updates an entry associated with the client in the second roster to indicate that the client is subscribed to the first roster as one of a participant or an observer. The client additionally updates an entry associated with the client in the first roster to indicate that the client is subscribed to the second roster as an observer.

Abstract: A method for folding sheets of a medium is provided. The method includes rotating a cam mechanism through a first period of rotation to cause a crease blade to move in a contact direction to create a crease in the sheets by pushing the sheets between a pair of first rolls, and rotating the cam mechanism through a second period of rotation to cause the crease blade to move in a retracting direction away from the sheets and cause a lever to move first and second scissor arms such that the pair of first rolls is separated and a pair of second rolls is separated. One of the second rolls is movable by the second scissor arm.

Abstract: A device for folding sheets of a medium is provided. The device has a frame; a cam mechanism attached to the frame; a lever attached to the frame, the lever being actuated by the cam mechanism; a first scissor arm attached to the frame, the first scissor arm being actuated by the lever; a pair of first rolls, one of the first rolls being movable by the first scissor arm; a second scissor arm attached to the frame, the second scissor arm being actuated by the lever; a pair of second rolls, one of the second rolls being movable by the second scissor arm; and a crease blade for contacting the sheets to create a crease in the sheets. Rotation of the cam mechanism through a first period of rotation causes the crease blade to move in a contact direction to create the crease in the sheets by pushing the sheets between the first rolls.

Abstract: Methods and apparatus for locating printouts are provided. In a method embodiment, a method of providing information generally includes generating directions to a first printer from a first location based on the location of the first printer and the first location. The method also includes presenting the directions to a user.
