Appl. No.:

12/982987

Inventors:

John Edward Borsuk - Nicholasville KY, US
Jie Chen - Lexington KY, US

Assignee:

Lexmark International, Inc. - Lexington KY

International Classification:

B65H 37/04

US Classification:

270 5811, 270 5808, 270 5813, 399410

Abstract:

A stapler system for an image forming apparatus according to one example embodiment includes a housing and a mounting device for mounting the housing to the image forming apparatus. A staple head is positioned within the housing for stapling media. A media sheet path is disposed within the housing for directing media received from the image forming apparatus to the staple head for stapling. When the housing is mounted on the image forming apparatus, a portion of the housing extends above an output bin of the image forming apparatus to permit delivery of stapled media from the housing to the output bin of the image forming apparatus.

International Classification:

H04W 64/00

US Classification:

4554561

Abstract:

Determining levels of geographic redundancy among radios of a wireless radio network is described. The level of geographic redundancy for a radio can affect the determination of location information for a user equipment (UE) on the wireless radio network. The disclosed subject matter can be employed in conjunction with timed fingerprint location (TFL) technologies to facilitate selection of radios employed in determining time values for TFL location determination. Levels of geographic redundancy can be employed to rank or order radios of a wireless radio network so as to reduce the likelihood of using geographically redundant radios in location determination. Further, rules can be selected to adjust threshold values and equations employed in determining the levels of geographic redundancy. Moreover, rules can be selected to apply boundary conditions to reduce the number of determinations formed for a set of radios of the wireless radio network.

International Classification:

G03G 21/16

Abstract:

A system for an electrophotographic image forming device includes a basket including a plurality of positioning slots each including cartridge datum locators that position a plurality of toner cartridges relative to the basket. A first guide rail and a second guide rail, each movable between a raised position and a lowered position, raise and lower the basket when the first and second guide rails move between the raised and lowered positions. In the raised positions the first and second guide rails support the basket permitting the basket to slide along the first and second guide rails into and out of the image forming device. When the first and second guide rails are in the lowered positions basket datum locators within the image forming device support the basket and position the basket relative to the image forming device in order to position the toner cartridges relative to the image forming device.

G03G 15/08

Abstract:

A system for an electrophotographic image forming device includes a basket insertable into and extendable out of the image forming device. The basket includes a plurality of positioning slots each configured to receive a corresponding toner cartridge of a plurality of toner cartridges. The basket includes a cartridge latching assembly configured to apply a hold-down force on each toner cartridge to rigidly hold each toner cartridge against corresponding datums of the basket. A basket latching assembly in the image forming device is configured to apply a hold-down force on the basket when the basket is inserted into the image forming device to rigidly hold the basket against corresponding datums of the image forming device for positioning the plurality of toner cartridges in respective operational positions within the image forming device with only the cartridge latching assembly of the basket directly applying hold-down forces on the plurality of toner cartridges.

Abstract:

A system for an electrophotographic image forming device includes a basket having a first side, a second side and a plurality of positioning slots extending between the first side and the second side, each positioning slot is configured to receive a corresponding toner cartridge. Each positioning slot includes a first latch at the first side of the basket and a second latch at the second side of the basket. Each of the first and second latches is independently pivotable between a latched position for applying a hold-down force on a respective end portion of a corresponding toner cartridge positioned in a corresponding positioning slot of the plurality of positioning slots to rigidly hold the corresponding toner cartridge against datums of the basket and an unlatched position to release the corresponding toner cartridge permitting removal of the corresponding toner cartridge from the basket.

H05B 33/08
F21S 8/08

Abstract:

A luminaire may include a plurality of different light engines. Light engines having different light distributions can be included in a single luminaire and a subset of the light engines selectively driven to dynamically change the light distribution of the luminaire. In this way, a single luminaire is capable of illuminating an area with a variety of different light distributions.

G03G 15/00

Abstract:

A media accumulator-ejector for use with an imaging apparatus. Rotatable upper and lower roll assemblies are located above and below a media accumulation zone comprised of an accumulation plate and positioned to receive media exiting an imaging device. The roll assemblies are moveable like jaws between an open position where media can accumulate on the accumulation plate without interference with the roll assemblies and a clamping position where the accumulated media is grasped by the upper and lower roll assemblies. The upper and lower roll assemblies are then rotated to eject the accumulated media from the accumulation plate. The upper and lower roll assemblies can also grasp and continuously eject individual sheets of media at a predetermined process speed.
