Abstract: A machine control and guidance system for an earthmoving machine, includes one or more sensors and a portable digital media device mounted on the earthmoving machine. The portable digital media device may comprise an iPhone, an iTouch, or other similar device. Each of the sensors senses the position or orientation of a portion of the earthmoving machine and provides a wireless output signal indicating the position or orientation. The portable digital media device is in wireless communication with each of the sensors. The device has an associated display and a memory in which is stored an application program which permits the device to determine the position of one or more portions of the earthmoving machine and to display the position of one or more portions of the earthmoving machine on the display.

Abstract: A print media cartridge for use in combination with a portable printer having a housing with a print media ingress in its lower rear wall and a print media egress in its top wall. The cartridge includes a housing having an elongated wall portion of generally U-shape cross section and two end wall portions closing the ends of the elongated portion, a roll of print media supported within the elongated wall portion with roll ends facing respective end wall portions; and a cartridge door of size and shape corresponding to the open side of the elongated U-shaped wall portion. The door is hingedly coupled to one lip of the elongated U-shaped portion and there are means for latching the door to the other lip of the elongated, U-shaped wall portion.

Abstract: An envelope holder is described for feeding envelopes through a printer. It comprises a pocket formed from an upper and lower sheet joined together, a window portion of which is removed to allow printing of an envelope held in the pocket. The holder is improved in that the upper sheet has longitudinal edges that extend only a fraction of the length of the lower sheet portion that forms the pocket. That fraction is between about 30% and about 85% of the lower sheet length.
