Abstract: A device for tensioning web, such as a plastics web dispensed from a shuttle in a wrapping machine, is disclosed. The wrapping machine usually includes an endless track positioned about an object to be wrapped and the shuttle travels on the endless track, dispensing the web as it goes. The rate at which web is dispensed varies as the shuttle progresses around the track and is dependent upon the shape of the track and the shape of the object to be wrapped. The web tensioning device attempts to maintain a constant tension in the web and includes a pair of rollers covered with resilient material. The rollers are urged together to form a nip with the resilient covering of the rollers compressed in the nip. The web is fed between the nip of the rollers.

Abstract: A system and method for reducing an image by receiving a scaling factor which defines a window. Input pixel intensities of the image are summed in real time as they are input and stored until all pixels within the window have been received. The sum is then divided by the number of pixels within the window which produces an average intensity. A pixel having the average intensity is output.

Abstract: A method and apparatus are disclosed for performing timely execution of periodic tasks in a redundant control system. A secondary controller in the redundant system receives a wakeup time array having at least one wakeup time element corresponding to a period task as well as a current time value from a primary controller, and schedules a run time for the periodic task at switchover based on the wakeup time element and the current time value from the primary control module. The secondary controller may further receive a task instance corresponding to the periodic task from the primary control module, and schedule a run time for the periodic task at switchover based on the task instance. In addition, the secondary controller may schedule a run time for the periodic task at switchover based on a default period associated with the periodic task, if no task instance and no wakeup time element were received corresponding to the periodic task.

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: A method and system implements selective, memory efficient, control over the amount of error diffused in a hybrid screening system. An image context error computer receives a pixel classification and an error value. Upon receiving these data, a set of shift registers supplies a fractional portion of the error value to an error diffusion circuit. A bypass thresholder receives screened video and applies simple thresholding. In parallel with the simple thresholding, an error diffuser receives screened video and applies error diffusion. The results of the two processes are output to a multiplexer which outputs one based on the pixel classification.

Abstract: A system and method for redundantly storing documents, specifically medical records, both on a local computer and on a remote server. A copy of patient data is stored remotely in the event of system problems, and to allow access to patient data from multiple sites. Data is stored on the local computer to speed retrieval of the data at a later date. When data stored on the local computer is newer or the same age as data stored on the remote server, the data is not downloaded from the remote server. If the local data is older than the data on the remote server, the data is downloaded from the remote server. Data may be displayed and organized utilizing a customizable, hierarchical “tree view.” Data may include image files, text files, and information about the files, such as the patient with whom they are associated, the time they were entered into the system, the time of the patient's next appointment, and the like.

Abstract: A modular cabinet includes a plurality of modular wall panels that interlock with one another via tubular connector assemblies. Each tubular connector assembly has a female tubular member attached to a modular panel and a male tubular member attached to an adjacent modular wall panel. The tubular connector assembly joins the modular panel and the adjacent modular panel to form a corner of the modular cabinet.

Abstract: A system and method are providing for implementing the blanking of an image of a skewed original document in a full image area where the blanking region is adjusted line-by-line and pixel-by-pixel, allowing an edge at an arbitrary angle to be masked. This system and method allow for skew blanking regions surrounding an image of a skewed original document so that no data from the original document is lost, by initially reducing the image of the original document to fit in the full image area, and all background artifacts from the platen show through and dirt from the top cover of the digital copier are removed.

Abstract: A system and method for selective scaling of an image by selective implementation of a window averaging processing technique or an interpolation processing technique. For enlargement scaling, the interpolation processor is implemented. For reduction scaling, the window averaging processor is implemented. For anamorphic scaling, the window averaging processor may be selected and implemented for reduction processing pursuant to a two-pass processing technique wherein the interpolator processing will be implemented thereafter.

Abstract: A bracket mount for precise antenna adjustment includes a lever or mechanical assist to permit slight movements to the antenna simply by manipulating the lever. The adjustable lever may be a built-in cam or yoke, or may be removably attached to the mount and antenna by an anchoring screw which acts to secure the antenna in place once the desired direction is achieved. The bracket mount may further include two adjusting levers, one for adjusting antenna direction in an up/down direction, and the other for adjusting the antenna in a left/right direction.

The graft prosthesis includes a purified, collagen-based matrix structure removed from a submucosa tissue source. The submucosa tissue source is purified by disinfection and removal steps to deactivate and remove contaminants, thereby making the purified structure biocompatible and suitable for grafting on and/or in a patient.

Abstract: An interlocked pipelined CMOS (IPCMOS) family of logic circuits provides extremely high performance pipelined operation and guarantees error free operation where variations in timing are compensated for automatically by the circuits. The IPCMOS logic circuits also provide a standard interface that makes it possible to interface different macro types easily. The IPCMOS logic circuits feature interlocking in both the forward and reverse directions. This “handshaking” guarantees error free timing and makes it possible to eliminate the need for a global clock at the macro level. Timing signals are generated locally at the macro level from the handshaking signals between macros. This makes it possible for the local circuits to deal with global timing variations caused by power supply noise, ACLV, and parameter variations. The macros operate in a pipelined mode with data advancing automatically from macro to macro with the timing controlled by the local handshaking signals.

The stand includes a base positioned on ground level and an elongated member extending upwardly from the base. The fan is mounted at the upper end of the elongated member, preferably about seven feet above ground level. The fan includes a housing containing an electric motor and a rotating shaft extending from the motor. The fan also includes fan blades radially extending from the motor shaft. The fan is mounted on the stand such that the motor shaft and fan blades are rotatable about a vertical axis to emulate a ceiling fan.

Abstract: A method of wire routing includes the steps of providing an array of cells on a semiconductor chip, determining a minimum distance location between a first clock point, an second clock point and a drive point for connecting to a connection point in the array of cells, and defining a wire path through an array of blockages disposed in the array of cells from the minimum distance location to the first clock point and from the minimum distance location to the second clock point to create a path for a wire for connecting the first clock point and the second clock point to a connection point such that skew is minimized between the starting clock point and the second clock point from the connection point when a clock signal is provided to the connection point from the drive point.

Abstract: A resampling application specific integrated circuit (RSA) supports image interpolation or decimation by any arbitrary factor in order to provide flexibility, and utilizes a neighborhood of up to 9.times.9 pixels to produce image data of high quality. The RSA contains a separate vertical and horizontal filter units for vertical resizing and horizontal resizing operations, vertical and horizontal position accumulator units, a configuration register unit for loading the vertical and horizontal position accumulator units, and a memory management unit to interface the RSA to external memory banks. The vertical and horizontal filter units contain nine multipliers and nine corresponding coefficient memories, with each memory preferably containing storage space for thirty-two coefficients. The coefficients are addressed on a pixel by pixel basis in response to the outputs of the vertical and horizontal position accumulator units.

Abstract: A trench DMOS transistor includes a buried layer region formed between the drain region and overlying drift region and having a doping type the same as that of the drift region and drain region. The buried layer region is more highly doped than the drain region or drift regions and is formed by e.g. implantation prior to epitaxial growth of the overlying drift region. By providing an optimized doping profile for the buried layer region, it is ensured that avalanche breakdown occurs at the buried layer region/body region. Thus drain-source on resistance is reduced because the JFET region present in prior art devices is eliminated, while device ruggedness and reliability are enhanced.
