Abstract: A system for monitoring alertness of a human while performing certain tasks. Alertness is detected herein by determining the tracking ability of the eye with respect to a visual disturbance, and is measured with respect to head motion. A decision circuit is provided when the motor response of the eye is deemed to be impaired as a result of drowsiness, inattention, or substance abuse.

Abstract: Random partial scans of a bar code label are utilized to re-create the entire symbol. The symbol is reconstructed by a re-match operation which places partial scanned data into memory and allows the data to be examined so that it is properly loaded whether data is acquired from scanning either the left or right side of the label first. Re-match allows labels having very small aspect ratios at extreme scanning angles to be readily captured.

Abstract: A system apparatus for altering the depth of field of a lens mechanism for use with a bar code. The altering of the mechanism allows different focal points and increased depths of field to be selected to accommodate different container sizes. The system is also designed to provide a variable threshold which adjusts the receiving circuitry based upon the amplitude of the signal received from the scanned label. Additionally, the system may be operated in a mode which introduces alternate threshold switching for allowing labels of low contrast bar and space elements to be successfully scanned along with elements of high contrast. Incorporated into the apparatus is a technique for adjusting the circuitry when there is a reduction of the power output of the beam generating laser.

Abstract: A container apparatus for small items such as drug medication. The container is designed for drugs or similar small articles which allows an attendant to dispense the items in accordance with printed or pictorial information provided upon the container or a separate sheet maintained within a pocket of the container.

Abstract: A dental handpiece is disclosed for rotating a bur in a housing having an enclosing cap, utilizing an air-driven, axial-flow turbine mounted on a shaft between two ball bearings, the assembly forming a removeable cartridge. Air is directed to the turbine through a combination plenum and nozzle ring. The cartridge is acoustically isolated from the cap and housing by two elastomeric rings having separate radial segments and axial pads. The radial segments support the cartridge bearings, prevent outer race rotation, compensate for dimensional variation of the elastomeric rings and cap and housing bores, and provide a means to vary suspension stiffness. The axial pads of the elastomeric ring around the front bearing provide a bearing pre-load force independent of the radial forces exerted on the bearing.

Abstract: An air driven dental handpiece is disclosed for rotating a bur in an angled housing that utilizes an arrangement of cooling water, chip air, and light services which are configured at their terminus into a form resembling a human eye. These services are integrated into an oval shape which is totally contained within the handle structure of the handpiece, and exit from the handle immediately adjacent the housing.In the handpiece, light is transmitted by optic fibers that are enclosed within a rigid, metallic sheath. Light is provided by a flexible fiber optic which abuts the entrance face of the handpiece sheath in a readily detachable, threaded coupling. A spring in the coupling presses the cable fibers firmly against the sheath fibers for maximum light transmission, and also holds the cable securely in the coupling.A flexible, multi-cavity supply hose includes four cavities which provide the five services of turbine air, turbine exhaust, water, chip air, and light.

Abstract: There is disclosed a double detection arrangement for minimizing soft errors emanating from a bubble memory. Soft errors are errors due to sporadic, periodic, and random noise which gives an erroneous indication of a bubble's presence. The arrangement provides double detection by sampling a bubble signal's wave shape on its positive and negative transition within a certain time frame. When a positive and negative transition are detected within a specified time frame, the presence of a bubble is considered to be present. Conversely, when only a single positive or only a single negative transition is detected within the time frame, the absence of a bubble or noise is assumed.

Abstract: A bubble memory device and method of fabrication are disclosed which establish that there is a correlation between bubble memory performance and the properties of a quartz film, which is interposed between the bubble film and metallic overlays, namely, the permalloy and/or conductor layers of the device. Specifically, it has been established that there is a correlation between improved device performance and a low p-etch rate which is a measurement that establishes certain elastic constants of the quartz (i.e., the response of the device to stress).

Abstract: A loading-unloading mechanism for magnetic heads used with a double-sided, rotating, flexible, magnetic disk is disclosed wherein the mechanism raises or lowers the heads for respectively executing a read/write operation or non-operation.

Abstract: A device for spincoating an ultra-thin iron powder film on a disk for magnetic recording. Ultra-thin films are utilized on magnetic disks in view of a high density recording that may be achieved on such devices. The invention develops an iron powder particulate composition which is pre-sheared to a particular consistency within a spin chamber which is compartmented by perforated vanes, disposed on a common axis with and above the magnetic disk, and is selectively coupled to the drive shaft of the disk spinner. Magnetic means are actuable to raise the bell-type cover of the spin chamber whereby to discharge coating material onto the spinning disk. Means decouple the chamber from the drive shaft and vary the spin rate of said shaft to effect the desired thinness of coating.

Abstract: The disclosure teaches how binary information may be stabilized in magnetic bubble lattice devices. In bubble lattice devices, information storage is determined by the state of the domain wall structure of the bubble. Fabrication means are disclosed for stabilizing two different types of bubbles found in such films.

Abstract: The invention pertains to an optical scanning system which is capable of reading the UPC (Universal Product Code) symbol, which is printed out of tolerance because the black bars are too wide and the white spaces are too narrow. The system provides an arrangement for selecting any one of three (3) modes of operation, wherein two (2) of the modes provide white space enhancement (a narrowing of the signals representative of the width of the black bars and a widening of the signals representative of the white spaces) and one (1) mode provides no enhancement at all.

Abstract: There is disclosed herein a fault-tolerant memory organization which permits through the incorporation of redundancy the utilization of circuit chips having defective sections. The apparatus involves the use of redundant sections fabricated on the chip in conjunction with a data relocation technique. The relocation scheme utilizes a code-decode arrangement which inserts zeros into the data stream to avoid the defective sections and provides a zero delete arrangement when the previously coded information is retrieved.
