摘要:
A fluid-ejection assembly of one embodiment is disclosed comprising first and second arrays of fluid-ejection mechanisms, first and second service stations, and first and second drive mechanisms. The first array ejects fluid onto media; the first service station is to service the first array. The second array ejects fluid onto the media; the second service station is to service the second array. The first drive mechanism moves the first array between a first position to eject fluid onto the media and a second position at the first service station, while the second array ejects fluid onto the media in place of the first array. The second drive mechanism moves the second array between a third position to eject fluid onto the media and a fourth position at the second service station while the first array ejects fluid onto the media in place of the second array.

Disclosed are printing systems and printhead assemblies in which yellow print nozzles are paired on a die with black print nozzles, with cyan and magenta print nozzles on a separate die. The pairing of yellow and black nozzles reduces constraints imposed by the printhead architecture and manufacturing processes.

Printmode selection systems and methods are described. In one embodiment, a method comprises receiving user input that pertains to selection of a printmode that is not a pre-defined printmode for a particular printer; and providing the user with feedback that pertains to a selected printmode.
摘要:
An exercise apparatus having a frame with attachments to multiple independent bidirectional resistance devices used by arms and/or legs of a user to provide resistance against movement of the user's appendages in two substantially opposed directions. The resistance devices may have a mechanism to control bi-directional resistance. The movement of the user's appendages in bi-directional resistance offers near full body exercise of agonist/antagonist muscles using flexion and extension action of larger muscle groups in a gait pattern, simultaneously. Hand engaging members attach to arm resistance devices and foot engaging members attach to leg resistance devices. The exercise apparatus may include an attached inclined backboard, mat, bench, or cushion to fully or partially support the user. The exercise apparatus may have separate height and/or length adjustment mechanisms for adjusting a range of motion of the user's appendages.
摘要:
A rehabilitative and/or exercise machine that has a frame with attachments to multiple independent bidirectional resistance devices (pneumatic, hydraulic, spring actuated, pulley system, cam, or any other resistance devices) used by the arms and/or legs to provide resistance against movement of the user's appendages in two substantially opposed directions. The resistance devices may have a mechanism such as one or more valves, brakes, springs, or the like that control bi-directional resistance. The action of the arms and/or legs in bi-directional resistance offers near full body exercise of the agonist/antagonist muscles using flexion and extension action of the larger muscle groups in a gait pattern, simultaneously. Hand engaging members attach to the arm resistance devices and foot engaging members attach to the leg resistance devices. The unit may include an attached inclined backboard, mat, bench, or cushion to fully or partially support the user, such as for the user to sit or lay on. The unit may have separate adjustment mechanisms for adjusting the height and/or length of the various portions of the unit to adjust the range of motion of the appendages. The unit may have devices to monitor pulse, oxygen flow and other vital signs.
摘要:
A method of one embodiment of the invention is disclosed that determines the temperature and/or firing resistance of a thermal fluid-ejection nozzle as the fluid-ejection nozzle is fired. The method determines whether the fluid-ejection nozzle ejected fluid upon firing based on the temperature and/or firing resistance of the fluid-ejection nozzle.
