20090034020 | ADJUSTING SCAN RATE WITHIN SCANNING DEVICE - A scanning device includes a scanning mechanism, a memory, a processing mechanism, and a scan rate adjustment mechanism. The scanning mechanism scans a media sheet having an image thereon at a variable scan rate, to yield raw data. The memory temporarily stores the raw data. The processing mechanism converts the raw data within the memory into processed data. The raw data is removed from the memory as the raw data is converted. The scan rate adjustment mechanism adjusts the variable scan rate, based on one or more of an amount of free space within the memory, a fill rate at which the raw data is filling the memory, and a removal rate at which the raw data is being removed from the memory, so that the memory does not become completely full. | 02-05-2009 |

20090278302 | Actuation Of Output Tray - One embodiment is an apparatus that has an input tray and an output tray. Commencement of a print job causes the output tray to move from a closed position to an open position. | 11-12-2009 |
20090283960 | SHEET FEEDER - A sheet feeder has a tray for receiving one or more media sheets. An arm is configured to pivot relative to the tray. A roller is rotatably coupled to the arm. A biasing device is coupled to the arm. The biasing device biases the arm to pivot toward the tray. | 11-19-2009 |
20090283964 | Systems And Methods For Orienting Media For Improved Scan Quality - Systems and methods systems and methods for orienting media for improved scan quality are disclosed. In an exemplary implementation, a method may include receiving a transparency media in a media holder, and guiding the transparency media into the media holder. The method may also include accepting the transparency media in the media holder only if the transparency media is oriented with an emulsion side facing toward an imaging surface. The method may also include self-ejecting the transparency media from the media holder if the transparency media is oriented with the emulsion side facing away from the imaging surface. | 11-19-2009 |
20090322017 | TORQUE LIMITER AND SHEET SEPARATING DEVICE HAVING A TORQUE LIMITER - A torque limiter may include a first member configured to rotate about a first axis and having a first contact surface. The torque limiter may include a second member configured to rotate about the first axis and including a first axially extending finger. The first finger may be radially biased so that a second contact surface defined by the first finger may contact the first contact surface with a normal force to define a predetermined torque value between the first and second members. When one of the first and second members is rotatably driven in a first rotational direction, the other of the first and second members may be rotatably driven in the first rotational direction unless a torque load greater than or equal to the predetermined torque value is applied to the other of the first and second members. | 12-31-2009 |
20100038847 | TRANSMISSION FOR AN AUTOMATIC DOCUMENT FEEDER - An automatic document feeder transmission includes a single electric motor mounted on a chassis. Motor actuates a power input gear that is rotatably mounted on the chassis and has gear teeth. A swing arm, rotatably mounted to the chassis, pivots about a swing arm pivot axis through an arc of travel. Arm has central and distal ends, the latter having gear teeth formed therein. Driving and driven pinions, each having mutually intermeshing gear teeth, are rotatably mounted to the arm. Driven pinion gear teeth also intermesh with power input gear teeth. A paper stop is rotatably mounted on the chassis. A catch, disposed on the arm, is selectively engageable with a wire spring disposed adjacent portion(s) of the travel arc, wherein arm rotation is selectively stopped in one direction and allowed in an opposite direction. Arm selectively switches between three discreet feeder modes and selectively actuates the paper stop. | 02-18-2010 |
20110228356 | Image scan device - Image scan device, comprising a platen, and a carriage, the carriage comprising a scan head, and a support structure arranged to move the scan head with respect to the platen, wherein a resilient element is provided that is arranged to bias the scan head in the direction of the platen, and resilient element fully extends between the platen and the bottom of the carriage, as seen from a direction parallel to the platen. | 09-22-2011 |
20130060196 | DRIVE MECHANISM FOR DRUG DELIVERY PUMPS WITH INTEGRATED STATUS INDICATION - A drive mechanism having integrated status indication includes a drive housing, a status switch interconnect, a drive biasing member, a piston, and a drug container having a cap, a pierceable seal, a barrel, and a plunger seal, wherein the drive biasing member is configured to bear upon an interface surface of the piston. Drive mechanism may include an incremental status stem having a stem interconnect, wherein the stem resides within the drive housing and the piston, and wherein the stem has an interconnect which engages one or more contacts on the piston to provide incremental feedback. A drug delivery pump with integrated status indication includes a housing and an assembly platform, upon which an activation mechanism, an insertion mechanism, a fluid pathway connection, a power and control system, and the drive mechanism having a drug container may be mounted. | 03-07-2013 |
20140012229 | DRIVE CONTROL MECHANISMS AND AUTOMATIC INJECTORS FOR INJECTABLE CARTRIDGES - An automatic injector includes a housing having a guide, a drive control mechanism, a transmission assembly, a motor, and an energy source. The housing may further include a cartridge cover. A drive control mechanism includes a drive screw, a cartridge carrier, a plunger carrier, and one or more control transfer instruments, such as a puck or cylinder. The drive screw interfaces and connects with the plunger carrier. The automatic injector is configured to accept a variety of syringes as cartridges for drug delivery. The cartridges may be ejected from the injector and safely disposed after use, making the injector a reusable automatic injector. The reusable automatic injector may further include one or more sensors, such as a cartridge sensor and a patient sensor. The novel incorporation of the drive control mechanisms into the automatic injectors of the present invention enables a single motor and transmission assembly to drive the function of multiple components, which may include the steps of: preparation and alignment of a cartridge for injection, removal of a safety cap or needle shield, needle injection, drug dose delivery, and syringe and/or needle retraction. Methods of manufacture and methods of use are also disclosed. | 01-09-2014 |
