Patent number: 6073033Abstract: A portable telephone device with telephone, data terminal and/or heads-up display functions in an integrated package having a size and weight on the order of conventional portable wireless telephones. The device includes a hand-held body structure having a main body portion and a heads-up display body portion. The main body portion may be held in a normal telephone handset position at a side of a user's head to position audio input and output transducers in functional relationship to the user's mouth and adjacent ear. The heads-up display body portion is rotatable from a storage position to an operative position for locating a display in front of the adjacent eye of the user for display of data. The device further comprises, within the hand-held body structure, a processor and associated memory, a keyboard, a transceiver for voice and data communications with a remote telephone and/or data terminal unit, and a battery compartment for housing a battery that supplies power to the device.Type: GrantFiled: November 1, 1996Date of Patent: June 6, 2000Assignee: Telxon CorporationInventor: James A.

Patent number: 6057681Abstract: A flux position sensor for magnetic bearings applications is provided by creating a secondary, or shunt, flux path in parallel with a main flux path of a magnetic bearing. The secondary flux path is formed such that a small amount of bearing magnetic flux is shunted from the main path into the secondary path. The amount of shunted flux varies in a known relationship with the flux density and/or the position of the element being supported by the bearing. By quantifying the amount of shunted flux, using any number of conventional methods, the position of the supported element can be determined. Therefore, the flux position sensor forms an integral part of a closed loop control system for an active magnetic bearing. The same sensor can be used simply for measuring flux density in a magnetic bearing or other device.Type: GrantFiled: June 12, 1997Date of Patent: May 2, 2000Assignee: Kingsbury, Inc.Inventors: Ronald W. Kipp, Joseph Imlach

Patent number: 5966463Abstract: Line-by-line dataform readers and methods are enabled to operate with reduced buffer memory capacity. Storage and retention of image data are controlled on an interactive basis by concurrent analysis while lines of image data are coupled from a linear scanner. In a first embodiment lines of image data are analyzed for recognition of a feature unique to a type of dataform. Upon successful feature recognition a series of earlier and later lines of image data adequate to include a complete dataform image are retained in memory for decoding purposes. Prior to successful feature recognition, as lines of image data exceeding a limited memory storage capacity are received the earliest stored lines are discarded on a first-in-first-out basis. In a second embodiment, a buffer memory has a storage capacity adequate to store only a partial dataform image.Type: GrantFiled: November 13, 1995Date of Patent: October 12, 1999Assignee: Meta Holding CorporationInventor: Ynjiun P.

Patent number: 5947050Abstract: A floating, drive-on dry dock assembly for a small craft is assembled from two kinds of hollow floatation units, tall units and short units. The units are interconnected so that their top surfaces are substantially coplanar. The units are arranged to form two arms which support the hull of the craft on each side of the longitudinal center line of the craft. The entire length of each arm is made up of tall units except the distal end portions of each arm which may be made up of short units. The short units are able to flex downward as a craft begins to ride up on the dock because of the location of the connection between adjacent units. The tall units, however, cannot flex relative to each other nearly to the same extent as the short units, and so they form a stable generally planar surface. The distal ends of the arms are connected to each other by an upside down short unit.Type: GrantFiled: October 29, 1997Date of Patent: September 7, 1999Assignee: Ocean Innovations, Inc.Inventors: W. Allan Eva, III, David T. Faber

Patent number: 5931113Abstract: A floating, drive-on dock for personal or commercial watercraft is assembled from a combination of hollow, air-tight floatation units. The dock includes a beam formed from a plurality of floatation units coupled together positioned underneath and attached to the dock to provide transverse support and lift for the floatation units and thereby reduce bowing or flexion when substantial forces are exerted, such as by large size watercraft, on the dock surface. Additionally, at least one of the floatation units that form the beam includes an aperture so that the buoyancy of that unit can be adjusted.Type: GrantFiled: September 12, 1997Date of Patent: August 3, 1999Assignee: Ocean Innovations, Inc.Inventors: W. Allan Eva, III, David T. Faber

Patent number: 5930435Abstract: Passive, self-adjusting and tracking optical wavelength filters are described. The filters are absorptive and can be of either transmissive or reflective type. The filters comprise an unpumped doped optical waveguide configured so that signals of different wavelength are spatially decoupled to some extent. The self-adjustment of the filter centre wavelength is achieved by the combined effects of the power-dependent saturable absorption, provided by an appropriate dopant, and partial longitudinal hole burning provided by the spatial decoupling of the different wavelengths. External cavity lasers using this type of filter in the external cavity are also described. This external cavity configuration can provide stable single frequency operation of, for example, a semiconductor laser. By using a saturable absorber for the external cavity (e.g. an erbium doped fibre), longitudinal mode-hopping can be suppressed, ensuring single frequency operation.Type: GrantFiled: May 1, 1997Date of Patent: July 27, 1999Assignee: University of SouthamptonInventors: Richard I. Laming, Wei-Hung Loh, David N. Payne, Michael N. Zervas

Patent number: 5916337Abstract: A pull ring to facilitate opening of pop-top or pull-top cans. The pull ring consists of a flat portion with two attached arms. The two arms defining an opening large enough to accommodate entry of a portion of the tab of the closure of the pull-top or pop-top can. The two arms and the flat portion define a aperture in communication with the opening which is large enough to contain the handle portion of the tab. The ring has one or more protrusions on the arms, opposite the flat portion, to aid gripping. The ring is movable from a down position, where it protrudes minimally from the can surface, to a deployed position, where it remains in place by means of a flat outer surface of the flat portion resting on the can's surface.Type: GrantFiled: September 2, 1997Date of Patent: June 29, 1999Inventors: Joseph E. Caniglia, Robert G. Caniglia

Patent number: 5571067Abstract: A cushioning conversion machine (10) comprises a frame (36), conversion assemblies (50, 52, 54, 56) which convert a stock material into a cushioning product, and a length measuring device (12) which determines the length of the cushioning product as it is being produced. The conversion assemblies include a rotating assembly (54) and the angular movement of this assembly directly corresponds to the length of the cushioning product. The length measuring device (12) is positioned to monitor the angular movement of the rotating conversion assembly (54) and thus the length of the cushioning product. In the preferred embodiment, the rotating conversion assembly (54) is a gear assembly.Type: GrantFiled: November 19, 1993Date of Patent: November 5, 1996Assignee: Ranpak Corp.Inventor: Richard O.

Patent number: 5542232Abstract: A packaging system comprising a cushion-creating machine (10) and a slide (12) positioned adjacent to the machine (10). The cushion-creating machine (10) includes a frame (36) and cushion-creating assemblies (50, 52, 54, and 56) which are mounted to the frame (36) and which create cushioning products (32). The machine frame (36) includes an exit through which the cushioning products (32) are discharged in a predetermined discharge direction D. The slide (12) includes a smooth sloped surface (60) with a top portion positioned proximate to the machine's exit so that the discharged cushioning products (32) will be deposited thereon. The smooth sloped surface (60) has a pitch angle which is sufficient to insure that cushioning products placed on the top portion of the surface will slide in a predetermined slide direction S. The smooth sloped surface (60) is oriented relative to the machine (10) in such a manner that the slide direction S is substantially perpendicular to the discharge direction D.Type: GrantFiled: November 19, 1993Date of Patent: August 6, 1996Assignee: Ranpak Corp.Inventor: Edwin P.
