  • Multi-Axial Bone Screw Assembly
    Publication number: 20100198270
    Abstract: A bottom-loading multi-axial bone anchor apparatus is disclosed. The apparatus includes a receiver member, a crown member, a bone anchor and a retaining member. The receiver member defines an upper opening and a lower opening, which may form part of the same opening, a channel, and a groove. The crown member and bone anchor are loaded into the lower opening of the receiver member, and the retaining member fits around the bone anchor and into the groove in the receiver member. The bone anchor is capable of multi-axial positioning with respect to the receiver member. An elongated member is placed in the channel of the receiver member, contacting the crown member, and a compression member is applied via the upper opening. The compression member presses down on the elongated member, which presses down on the crown member and locks the bone anchor between the crown member and the retaining member.

  • Orientation determination utilizing a cordless device
    Patent number: 7737393
    Abstract: A system for generating orientation information includes a reflector, an image collection system, and a processor. The image collection system is configured to collect at least two sets of image data, where one set of image data includes a stronger indication of the reflector than the other set of image data. The two sets of image data are collected using at least one reflector with some orientation-specific characteristic or a reflector integrated into a device that includes some orientation-specific structural feature. Once collected, the two sets of image data are used to generate orientation information related to the reflector. In particular, orientation information related to the reflector is generated by taking the difference between the two sets of image data.

  • VERTEBRAL IMPLANT INSERTER AND METHOD OF USE
    Publication number: 20100131020
    Abstract: A surgical installation tool to insert a vertebral implant into a patient includes an elongated handle and a head attached to one end. The vertebral implant may be attached to the head. The head may include an engagement member that is movable between engaged and released positions. The engagement member may be outwardly biased so that it naturally rests in the released position. The engagement member may be inwardly movable from the released position to the engaged position. A reactive force caused by the inward deflection may supply the attachment force between the installation tool and the vertebral implant. The attachment between the vertebral implant to the installation tool may be maintained while the engagement member is in the engaged position.

  • Surgical instrumentation for rod reduction
    Patent number: 7722617
    Abstract: One embodiment of the present application includes a surgical instrument comprising a first member and a second member that are pivotally interconnected together. The first member and the second member each include a proximal end structured for manual manipulation by an operator and a distal end defining a gripping nose structured to engage a bone anchor. The instrument further includes a bearing surface to contact an implantable rod when the gripping nose is engaged with a bone anchor and to urge the rod toward the bone anchor when the gripping nose is pivoted thereabout. A thread guide is included that is engaged by threading of a rotatable member. The rotatable member can include a swivel-mounted head structured to bear against and further urge the rod toward a seat in the bone anchor when the rotatable member is turned through the guide.

  • Safe eye detection
    Patent number: 7695138
    Abstract: An eye detection system for safe detection of the eye positions of a subject estimates the distance from the eye detection system to the subject and reduces the power level of at least one primary light source of the eye detection system if the subject is too close to the eye detection system. If the subject is not too close to the eye detection system, the power level of the at least one primary light source of the eye detection system is increased, provided the power level is below a predetermined maximum power level. Primary light from the at least one primary light source reflected from the subject is sensed by an imager to obtain one or more images, from which the eye positions of the subject are estimated.

  • Dipole antennas and coaxial to microstrip transitions
    Patent number: 7692601
    Abstract: The invention relates in part to a folded dipole having a dipole axis and a pair of arms which together have a profile which is concave on one side and convex on the other when viewed along the dipole axis. The dipoles may be arranged as a dipole box around a central region, typically in a generally circular or square configuration. Further elements may be placed in the dipole box or in the gaps between dipole boxes. The antenna may be a single-band antenna, or a multi-band antenna with the further elements operating in a different frequency band to the dipole boxes. The further elements may be concentric dipole boxes. The invention is particularly suited for use in a cellular base station panel antenna. A novel coaxial to microstrip transition is also described.

  • METHOD FOR CATALOGING AND STORING DATA IN A CONTROL SYSTEM
    Publication number: 20100077137
    Abstract: A method includes receiving a data input file, the data input file defining a first set of data fields to be included in a database and including a set of data elements to be included in the database. The method also includes identifying a second set of data fields in the data input file that are designated to contain a Boolean element, said second set of data fields being a subset of the first set of data fields. The method further includes defining at least one new data field, each new data field collectively storing a plurality of the Boolean elements. The first set of data fields are modified to eliminate the second set of data fields. The method also includes storing in a catalog data that defines an arrangement of the first set of data fields, wherein the arrangement includes the at least one new data field for collectively storing the Boolean elements.

  • MULTIMODE VOLTAGE REGULATOR CIRCUIT
    Publication number: 20100026250
    Abstract: A multimode voltage regulator circuit includes a linear regulator sub-circuit configured to supply current to a load in a low-current mode, responsive to a first control signal from a first control path, as well as a switching regulator sub-circuit configured to supply current to the load in a high-current mode, responsive to a second control signal from a second control path. The circuit further comprises a shared error amplifier configured to generate an error signal based on the difference between a reference voltage and a feedback signal coupled from the load, and a switch configured to selectively route the error signal to the first control path in the low-current mode and to the second control path in the high-current mode.

  • POSITION DETERMINATION UTILIZING A CORDLESS DEVICE
    Publication number: 20100001950
    Abstract: A system for generating position information includes a reflector, an image collection system, and a processor. The image collection system is configured to collect at least two sets of image data, where one set of image data includes a stronger indication of the reflector than the other set of image data. The two sets of image data can be collected in many different ways and may include using a retroreflector as the reflector. The two sets of image data are used to generate position information related to the reflector. In particular, position information related to the reflector is generated by taking the difference between the two set of image data. Because one set of image data includes a stronger indication of the reflector than the other set of image data, the difference between the two sets of image data gives a definitive indication of the reflector's position.
