Abstract

Disclosed are systems and methods for transmitting graphical data via a communication line. For example, in one embodiment, a system includes means for receiving voice data, means for generating graphical data representative of a user input, and means for simultaneously transmitting the voice data and information representative of the generated graphical data via a communication line such that a bandwidth of the communication line is not exceeded.

Claims

1-38. -38. (canceled)

39. A conveyor system comprising:

a feeder section configured to convey objects in parallel columns, the objects of the columns being located at random positions along a longitudinal direction of the feeder section;

a timing section comprising a timing conveyor belt including a plurality of rollers each having an axis of rotation perpendicular to a longitudinal direction of the timing conveyor belt, the timing conveyor belt further including stop members provided at predetermined positions along a length of the timing conveyor belt, the stop members being adapted to limit travel of the objects traveling along the timing conveyor belt; and

a cam positioned adjacent the timing conveyor belt and adapted to engage the rollers;

wherein when the cam engages the rollers, the rollers rotate to drive the objects along the timing conveyor belt toward respective stop members that halt their travel, such that the positions of the objects can be controlled to coincide with the predetermined positions of the stop members.

40. The system of claim 39, wherein the stop members comprise friction pads upon which the objects come to rest.

41. The system of claim 39, wherein the stop members comprise flights against which the objects abut.

42. The system of claim 39, wherein the timing section comprises two parallel timing conveyor belts each including a plurality of rollers having an axis of rotation perpendicular to a longitudinal direction of the timing conveyor belt, the timing conveyor belts further including stop members provided at predetermined positions along lengths of the timing conveyor belts, the stop members being adapted to limit travel of the objects traveling along the timing conveyor belts.

43. The system of claim 42, wherein the stop members of one of the timing conveyor belts are positioned so as to be staggered relative to the stop members of the other timing conveyor belt along the longitudinal directions of the timing conveyor belts, such that objects in the columns can be positioned out-of-phase relative to each other along the longitudinal directions of the time conveyor belts.

44. The system of claim 42, wherein the stop members of each timing conveyor belt are equally spaced along the longitudinal directions of the timing conveyor belts.

45. The system of claim 39, wherein the timing conveyor belt comprises two columns of stop members aligned along the longitudinal direction of the timing conveyor belt, such that the positions of two columns of objects can be controlled with the timing conveyor belt.

46. The system of claim 45, wherein the stop members of the two columns are positioned on the timing conveyor belt so as to be staggered relative to each other along the longitudinal direction of the timing conveyor belt, such that objects in the two columns can be positioned out-of-phase relative to each other along the longitudinal direction of the time conveyor belt.

47. The system of claim 45, wherein the stop members of each column are equally spaced along the longitudinal direction of the timing conveyor belt.

48. The system of claim 39, further comprising a singulating section adapted to receive the columns of objects from the timing section, direct the objects laterally into a single column, and convey the single column of objects along a longitudinal direction of the singulating section.

49. A method for controlling conveyed objects, the method comprising:

conveying objects in parallel columns to a timing section;

controlling the positions of the objects within each column along a longitudinal direction of the timing section such that the objects of one column are out-of-phase relative to the objects of the another column, the controlling comprising driving the objects of each column forward along a timing conveyor belt toward stop members positioned at predetermined positions along a length of the timing conveyor belt, the stop members being adapted to halt further travel of the objects;

conveying the columns of objects to a singulating section;

combining the columns of objects into a single column with the singulating section; and

conveying the objects in the single column to a subsequent processing section.

50. The method of claim 49, wherein driving the objects of each column comprises driving the objects of each column along separate timing conveyor belts each having a plurality of stop members.

51. The method of claim 50, wherein the stop members of one of the timing conveyor belts are staggered relative to the stop members of the other timing conveyor belt.

52. The method of claim 49, wherein driving the objects of each column comprises driving the objects of each column along a single timing conveyor belt having two columns of stop members.

53. The method of claim 52, wherein the stop members of one of the columns are staggered relative to the stop members of the other column.

54. The method of claim 49, wherein the stop members comprise friction pads upon which the objects come to rest.

55. The method of claim 49, wherein the stop members comprise flights against which the objects abut.

56. A timing conveyor belt comprising:

a top surface and a bottom surface;

a plurality of rollers mounted within cavities provided in the timing conveyor belt, the rollers extending beyond the top and bottom surfaces of the timing conveyor belt and being adapted to propel an object along the timing conveyor belt when the rollers contact a cam; and

friction pads provided at predetermined positions along a length of the timing conveyor belt;

wherein objects propelled along the timing conveyor come to rest on the friction pads at the predetermined positions.

57. The conveyor belt of claim 56, wherein axes about which the rollers rotate are perpendicular to a length of the conveyor belt.

58. The conveyor belt of claim 56, wherein the friction pads are equally spaced from each other.

59. The conveyor belt of claim 56, wherein the friction pads are arranged in two staggered columns aligned along a length of the conveyor belt.
