Abstract: A point of sale printer includes a paper supply mechanism rotatably mounting a paper supply roll within a frame through a resiliently mounted bearing member extending into each end of a central hole in the roll. The frame is manually pivoted between an open position, in which the roll is installed and removed by moving the bearing members outward with movement of the roll, and a closed position, in which the roll is rotatably held in place, with outward movement of the bearing members being prevented by stops within the printer. With the frame in its closed position, a paper web is pulled from the roll for printing. An alternate configuration allows the printer to use a narrow paper roll.

Abstract: A plug for stopping the flow of bone cement in a channel within bone, such as the intramedullary bone canal or a previously prepared channel, includes an elastomeric inflatable structure protected from bone fragments and sharp edges by a shield extending around distal and peripheral sides of the inflatable structure. This inflatable structure is preferably formed as a sleeve extending around a core. The shield includes a distal end fastened to the core and a flexible portion expandable with inflation of the inflatable structure. The core is also removably connected to an insertion tool, with passageways in the insertion tool and in the core being used to insert a fluid into the inflatable structure. A valve extends as a sleeve around the core, and over the passageway, allowing fluid to flow into the inflatable structure, but preventing it from flowing out of the inflatable structure.
Abstract: A point of sale printer is provided with a large paper supply roll mounted externally from the printer. The printer includes a paper drive which rapidly accelerates and decelerates a paper web extending from the paper supply roll. A tensioning roll is moved in one direction to feed the web into the printer during the relatively slow acceleration of the paper supply roll and in an opposite direction to prevent a tangle of paper as the paper supply roll is decelerated after the printer stops moving the paper web. A cable assembly is provided to facilitate loading the large paper supply roll. A braking spring helps to decelerate the paper supply roll and further engages a flap formed in an outer end of the paper web to thread this end of the web into the printer.

Abstract: A portable unit assists a visually impaired user within a store by providing an output, using speech synthesis, of his location based on reading various barcode labels. The location of each barcode label is determined from data stored within the portable unit. The portable unit also determines a path between the user's location and an item he selects to find, describing the path using speech synthesis. The user can select, by speech or by depressing a button, items for a target list. Preferably, some barcode labels identify an end of an aisle, which cause the portable unit to describe, using speech synthesis, items on the aisle and items in the target list on the aisle.

Abstract: A device for reading magnetically encoded data on a document, such as a strip of characters printed in magnetic ink along the lower edge of a check, executes a subroutine to determine whether each character, as it is read, is legitimate. This error detection may be done by comparing recognized code patterns with legitimate code patterns, or by comparing a signal representing the strength of the signal derived from the output of the magnetic read head reading the data with a predetermined level. If an error is detected, the magnetically encoded data is read and checked again, as often as need up to a predetermined number of attempts to read the data.

Abstract: A printer mechanism includes a single motor turning a system drive gear in a paper feeding direction, and in a cam driving direction, opposite the paper feeding direction. When the system drive gear is turned in the paper feeding direction, a paper feeding spring clutch drives a paper feed roll with the system drive gear. When the system drive gear is turned in the cam driving direction, a drive cam is driven by a cam driving spring clutch. The drive cam has a first surface driving a moving knife blade across a stationary knife blade in a cutting direction, and in a return direction opposite the cutting direction. With this movement in the cutting direction, the moving knife is held against the stationary knife blade, and, with movement in the return direction, the moving knife is moved away from the stationary knife blade, by means of a second surface of the drive cam.

Abstract: A suction probe system for cleaning debris from a surgical site includes a probe tip, a filter unit in fluid communication with the probe tip, and a suction source in fluid communication with the filter unit. The filter unit includes a cylindrical filter having an inner chamber attached to the suction source and an outer surface which accumulates debris particles too large to pass through holes within the cylindrical filter. The filter unit also includes a slider having an open-ended cylinder which is slid along the outside of the cylindrical filter to remove accumulated debris particles and to push these debris particles into a reservoir within the filter unit. The slider and the probe tip can be made integral parts of a single sliding member.
Abstract: Apparatus for monitoring fan speeds within a computing system includes a tachometer turning with the fan, providing a tachometer signal including a number of pulses during each revolution of the fan. This tachometer signal is provided as an input to a signal generator in the form of a flip-flop, which generates a square-wave signal having transitions between high and low levels corresponding to tachometer signal pulses. The square-wave signals are provided as inputs to separate input ports of a microprocessor. These input ports are sequentially sampled at a rate providing at least two samples per period of the fastest square-wave signal, so that transitions of each square wave signal during a predetermined time interval can be detected and counted. For each input port, the number of counted transitions is compared to a stored acceptable value to establish whether the fan is operating in an acceptable speed range.
