13. The apparatus of claim 7 wherein the proximal end of the tube is coupled to a frame with a retainer and the push rod extends through the frame.
14. A method for dispensing material from a squeeze tube where the squeeze tube has a distal end for dispensing the material and a proximal end, the method comprising:
attaching the proximal end of the tube to a frame;
positioning rollers on opposing sides of the tube; and
pushing the rollers towards the distal end of the tube, thereby dispensing material from the tube.
15. The method of claim 14 wherein the attaching step comprises:
placing the proximal end of the tube in a retainer; and
pressing the retainer plates together for gripping the tube.
16. The method of claim 15 wherein the positioning step comprises;
placing a first roller against one side of the tube; and
placing a second roller against the other side of the tube.
17. The method of claim 15 wherein the pushing step comprises;
providing an energy source for pushing the rollers; and
applying energy from the energy source for furnishing a pushing force to the rollers.
18. The method of claim 17 wherein the pushing force is coupled to the rollers by a push rod and roller holder.
19. The method of claim 17 wherein the energy source is a user of the method.
20. The method of claim 14 wherein the rollers are removed from the sides of tube and the tube is detached from the frame when dispensing is no longer desired.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method for operating an image display apparatus, comprising:
receiving broadcast channel information;
classifying channels into a 2D channel, a 3D channel or a mixed channel based on the received channel information; and
displaying a channel list obtained by classifying the channels on a display if a channel list display command is input.
2. The method according to claim 1, further comprising displaying a broadcast image of a received channel,
wherein the displaying of the channel list includes displaying the broadcast image on the display along with the channel list.
3. The method according to claim 1, further comprising, if a predetermined channel is selected from the channel list, displaying a broadcast image of the selected channel.
4. The method according to claim 3, further comprising displaying, if a channel movement command for moving the channel to a previous channel or a next channel is input after the predetermined channel is selected from the channel list, displaying a broadcast image of the previous channel or the next channel within channels of the same type as the selected channel.
5. The method according to claim 3, further comprising displaying an object indicating that the channel will be moved within a channel type, to which the selected channel belongs, after the predetermined channel is selected from the channel list.
6. The method according to claim 3, further comprising displaying an object indicating whether the displayed broadcast image is a 2D image or a 3D image, if the selected channel is a mixed channel.
7. The method according to claim 1, wherein the classifying of the channels is performed upon automatic channel search.
8. The method according to claim 1, wherein the channel list includes at least one of a 2D channel list, a 3D channel list or a mixed channel list.
9. The method according to claim 3, further comprising displaying a broadcast image of a channel of a type different from that of the selected channel, if a channel movement command for moving the channel to another type of channel is input after the predetermined channel is selected from the channel list.
10. A method for operating an image display apparatus, comprising:
displaying, on a display, a channel list obtained by classifying channels into a 2D channel, a 3D channel or a mixed channel based on received channel information;
if a predetermined channel is selected from the channel list, displaying a broadcast image of the selected channel; and
if a command for moving the channel to a previous channel or a next channel is input, displaying a broadcast image of the previous channel or the next channel within channels of the same type as the selected channel.
11. An image display apparatus comprising:
a display configured to display an image;
a memory configured to store a channel list obtained by classifying channels into a 2D channel, a 3D channel or a mixed channel based on received channel information; and
