Abstract: The automatic vent damper has various embodiments of a wind actuated vent system, which automatically closes to preclude entry of wind blown water when a wind of predetermined velocity and direction acts upon the device. The damper may be installed as an off-ridge or ridge vent system, or in other operating environments and installations as desired. Various mechanisms are used to operate the device, with all including one or more springs, which hold a rigid door or flap, open in light wind conditions. However, when a wind of sufficient velocity blows toward the vent opening, the door or flap is closed due to aerodynamic forces thereon to preclude entry of wind blown water into the device. The door or flap automatically opens again due to the spring mechanism when the wind abates.

Abstract: A barbed medical prosthesis is disclosed in which the barb includes a basal portion comprising a point of union with the substrate of origin (such as a strut), an anchoring portion adapted to embed into tissue, and a stress-dispersing portion located between the basal and anchoring portions. In one embodiment the stress-dispersing portion comprises a helical coil having a free winding that is unattached to the strut from which the barb extends. In another embodiment, the stress-dispersing portion comprises a series of bends or curves formed in the barb proximate to the point of union with the strut. The barb can be mechanically attached and/or soldered to the prosthesis, or integrally formed therefrom. A second barb portion and stress-dispersing portion, may also extend from the basal portion.

Abstract: A hydraulic system for steering an aircraft while taxiing selectively applies pressurized fluid to different ports of a hydraulic motor to turn a landing gear wheel either left or right. Shimmy of the landing gear attached to the wheel is dampened by a device that is coupled across the hydraulic lines that are connected to the motor. That device has a piston in a bore with one hydraulic line connected via an orifice to a first chamber on one side of the piston and the other hydraulic line connected via a different orifice to a second chamber on the other side of the piston. The piston stroke is limited to control the effective oscillation damping amplitude. The shimmy produces an oscillating pressure differential in the two hydraulic lines which is dampened by the device.

Abstract: A media stack height sensor in an image forming apparatus with a flag arm that is in contact with a top surface a media stack. The arm is coupled to a flag characterized by varying transmissivity. The flag is moveable by the flag arm so that as the position of the arm changes in relation to the stack height, a different portion of the flag is positioned between a transmitter and receiver of an optical sensor disposed within the body of the image forming apparatus. The flag accordingly reduces the amount of optical energy received by the receiver. The receiver output signal indicates the height of the media stack. The flag also includes features that further limit light transmission to the receiver to provide discrete stack height indications such as low, empty, full, or intermediate states.

Abstract: Leakage current control devices include a circuit having one or more functions in a data path where the functions are executed in a sequence. Each of the functions has power reduction logic to energize each respective function. A leakage control circuit interacts with the power reduction logic, so that the functions are energized or deenergized in a control sequence such that the functions where the data is resident are energized and at least one of the other functions is not energized.

Abstract: An apparatus and method for externally managing data within an asynchronous pipeline. The asynchronous pipeline over which control is sought includes a data path and a control path. In accordance with the method of the present invention, a data tag value is assigned to the data prior to its entry into the asynchronous pipeline. The data tag value is sent into the control path at the same time the data is sent into its data path such that the data tag value passes through the asynchronous pipeline in parallel with the data to which it is assigned. At a given stage within the asynchronous pipeline, the data tag value is compared with a control tag value, and only in response to the data tag value matching the control tag value is the data permitted to pass to the next stage within the asynchronous pipeline.

Abstract: An image forming apparatus includes a waste toner system that collects waste toner in a waste toner container. An amount of waste toner collected in the container is increased by using a driven toner distributing member that distributes accumulated toner within the container. The waste toner system may detect the accumulation of waste toner by monitoring a drive control circuit while the toner distributing member is being driven. For example, the system may detect excess accumulation by comparing the monitored values of a frequency control signal with one or more reference values corresponding to nominal accumulation conditions. An extension may be employed whereby movement of the toner distributing member creates interference between the toner distributing member and the container when the toner distributing member reaches a predetermined position. The interference may be detectable from the drive control circuit as an indication of a full condition.

Abstract: A classifier for classifying particulates entrained in a flowing stream of gas is configured such that a change of direction of gas flow causes particles to impinge upon a target, heavier particles being trapped in a downwardly extending fluidized trap. The classifier is easily constructed, has no moving parts, and can take the place of sifters and other equipment traditionally used for classifying such product streams.

Abstract: An image forming apparatus includes a waste toner system that collects waste toner in a waste toner container. An amount of waste toner collected in the container is increased by using a motor-driven toner distributing member that distributes accumulated toner within the container. The waste toner system may detect the accumulation of waste toner by monitoring a motor control circuit while the toner distributing member is being driven. For example, the system may detect excess accumulation by comparing the monitored values of a speed control signal with one or more reference values corresponding to nominal accumulation conditions. Whether or not the motor is speed controlled, the apparatus may use a shared motor that drives one or more image forming process members and the toner distributing member. A drive arrangement may be used to selectively drive the toner distributing member based on motor direction to avoid interfering with image forming operations.

Abstract: An apparatus and method for ink-jet printing onto an intermediate drum in a helical pattern while correcting for image skew and aliasing. A plurality of ink-jet print heads place an image on an intermediate drum, impervious to ink, in a helical patter. To compensate for helical printing, the image is altered by nozzle placement and image manipulation to correct for skewing errors, and thereafter, the nozzle timing is adjusted to correct for aliasing. The plurality of print heads move parallel to the axis of rotation of the drum while the drum is simultaneously rotating, causing the image to be placed in a helical pattern. Once the entire image is placed on the drum, paper is rolled against the drum under pressure and the image is transferred thereto.
