摘要： The present disclosure provides an audience response system with dynamic user interfaces and methods of using such an audience response system. The audience response system includes a wireless aggregation point and multiple remote handsets communicatively coupled to that wireless aggregation point. The remote handsets may be used (e.g., by students) to answer questions (e.g., posed by a teacher). At least some of the remote handsets may include user interfaces that include user input interface elements that are configurable via the wireless aggregation point. Additionally, the user interfaces of at least some of the remote handsets may provide feedback to the students regarding their interaction with the remote handsets.

摘要： A method and system for determining whether a first one of a plurality of labels on a roll of label stock is a full label. The method includes sensing a leading edge of the roll of label stock, sensing a location of a first one of a plurality of indicator marks (254) that are printed on the back side of the roll of label stock, sensing a location of a second one of the plurality of indicator marks (254), sensing a location of one of a plurality of top of form marks (252) that are printed on the back side of the roll of label stock. The method further includes determining whether the first one of the plurality of labels is a full label based on the leading edge of the roll of label stock, the location of the first one of the plurality of indicator marks, the location of the second one of the plurality of indicator marks, and the location of the one of the plurality of top of form marks.

摘要： An instrument includes an instrument body having an opening (22) at one end. A valve (24) is mounted within the instrument body, the valve having an opening at one end. A lid (26) is integrally molded with the valve and hingedly movable with respect to the valve opening. An actuating arm (28) is operatively connected to the lid, the actuating arm transmitting forces from an instrument movement mechanism to the valve door under both tension and compression. As a result, the lid (26) is opened and closed substantially solely by the actuating arm.

摘要： An activity center is provided that includes a case having an upper and lower shell (12,14) hingedly joined together. The upper shell (12) has a recessed portion disposed on a top surface that receives a writing surface (40) that is hingedly joined to the top surface of the upper shell. The recessed portion is adapted to receive a paper or template including indicia between the top surface and the writing surface and the indicia on the paper or template is at least partially visible through the writing surface.
