20110217153 | System For Attaching A Tool To A Work Machine - A carrier is provided for releasably attaching a tool to the lift arms of a work machine. The carrier comprises a lift arm attachment point for attachment to the lift arm, a tool attachment point for releasable attachment of the tool to the carrier, and a contact pad, for contacting the tool in use. In use, the lift arm and contact pad lie in the same vertical plane. Providing a contact pad between the carrier and tool in line with the lift arm removes any transverse bending forces on the carrier. | 09-08-2011 |
20120189374 | Latching System For Securing An Implement To A Carrier Mounted To A Lifting Arm - A remotely operable latching system is provided for securing an implement to a carrier mounted to a forward end of a lifting arm for pivoting about a horizontal tilt axis. The latching system is mounted to the carrier and includes a latching rod arrangement operated by an extensible and retractable linear electric motor between a retracted latching position and an extended unlatching position. A secondary latch arrangement is provided for rotating the latching rod arrangement to an arrested position preventing movement of the rod arrangement to its latching position once the latching rod is extended to its unlatching position. Movement of the rod arrangement to its arrested position is aided by a spring and by the electric motor. Release of the rod arrangement from the arrested position is done by rolling the carrier back towards the lifting arms bringing the latching rod arrangement into contact with the arm so as to pivot the rod arrangement out of its arrested position. A microprocessor based control unit is coupled to the electric motor and acts in response to a boom height input signals to prevent operation of the motor when the boom is above a preset height. Further, an LED indicator light operates in certain modes which apprise the operator of various operating conditions. For example, the LED light blinks slowly when the latching rod arrangement is being extended to its unlatch position, blinks rapidly if the latching rod jams causing an overload condition and gives a steady light when the latching rod arrangement is fully extended. Various timing requirements are also programmed into the control unit. | 07-26-2012 |
20140064835 | FOLDING PARKING STAND - A tractor-mounted front loader includes a parking stand mounted to each of a pair of downwardly and forwardly inclined arm sections coupled to an implement resting on the ground. Each parking stand includes a support leg and a brace, the latter having a rear end pivotally mounted to a location approximately halfway between opposite ends of the support leg and an forward end pivotally mounted to a lower region of an associated loader arm section. The support leg and brace may be stored on the loader arm section by folding them together with a catch carried by the brace becoming releasably engaged with the support leg. The folded support leg and brace are then pivoted against the loader arm section and secured to it by a releasable latch which secures the top of the support leg to the arm section to establish a stored position. | 03-06-2014 |

20110065585 | SYSTEMS, METHODS AND APPARATUS FOR MEASURING MAGNETIC FIELDS - SQUIDs may detect local magnetic fields. SQUIDS of varying sizes, and hence sensitivities may detect different magnitudes of magnetic fields. SQUIDs may be oriented to detect magnetic fields in a variety of orientations, for example along an orthogonal reference frame of a chip or wafer. The SQUIDS may be formed or carried on the same chip or wafer as a superconducting processor (e.g., a superconducting quantum processor). Measurement of magnetic fields may permit compensation, for example allowing tuning of a compensation field via a compensation coil and/or a heater to warm select portions of a system. A SQIF may be implemented as a SQUID employing an unconventional grating structure. Successful fabrication of an operable SQIF may be facilitated by incorporating multiple Josephson junctions in series in each arm of the unconventional grating structure. | 03-17-2011 |
20150032991 | SYSTEMS AND METHODS FOR INCREASING THE ENERGY SCALE OF A QUANTUM PROCESSOR - Increasing the energy scale of a quantum processor improves its performance. Energy scale of a quantum processor may be increased by increasing the coupling strength of communicatively coupled superconducting devices comprised in the quantum processor. Configuring the physical dimensions of communicatively coupled superconducting devices such that an intentional direct coupling is induced between a pair of superconducting devices communicatively coupled by a coupling device may controllably add an additional mutual inductance to the mutual inductance of the pair of superconducting devices. Furthermore, reducing the beta parameter of a coupling device may improve the tunability of the coupling device. The combined effects of improved tunability of the coupling devices and the increased coupling strength between superconducting devices communicatively coupled by respective coupling devices comprised in the quantum processor may thus improve the performance of the quantum processor. | 01-29-2015 |
20150032993 | SYSTEMS AND METHODS FOR ACHIEVING ORTHOGONAL CONTROL OF NON-ORTHOGONAL QUBIT PARAMETERS - Achieving orthogonal control of non-orthogonal qubit parameters of a logical qubit allows for increasing the length of a qubit chain thereby increasing the effective connectivity of the qubit chain. A hybrid qubit is formed by communicatively coupling a dedicated second qubit to a first qubit. By tuning a programmable parameter of the second qubit of a hybrid qubit, an effective programmable parameter of the hybrid qubit is adjusted without affecting another effective programmable parameter of the hybrid qubit thereby achieving orthogonal control of otherwise non-orthogonal qubit parameters. The length of the logical qubit may thus be increased by communicatively coupling a plurality of such hybrid qubits together. | 01-29-2015 |
20150262073 | SYSTEMS AND METHODS FOR REMOVING UNWANTED INTERACTIONS IN QUANTUM DEVICES - Systems, devices, articles, methods, and techniques for advancing quantum computing by removing unwanted interactions in one or more quantum processor. One approach includes creating an updated plurality of programmable parameters based at least in part on a received value for the characteristic magnetic susceptibility of the qubit in the at least one quantum processor, and returning the updated plurality of programmable parameters. Examples programmable parameters include local biases, and coupling values characterizing the problem Hamilton. Also, for example, a quantum processor may be summarized as including a first loop of superconducting material, a first compound Josephson junction interrupting the first loop of superconducting material, a first coupler inductively coupled to the first loop of superconducting material, a second coupler inductively coupled to the first loop of superconducting material, and a second loop of superconducting material proximally placed to the first loop of superconducting material inductively coupled to the first coupler and the second coupler. | 09-17-2015 |

20160132785 | SYSTEMS AND METHODS FOR OPERATING A QUANTUM PROCESSOR TO DETERMINE ENERGY EIGENVALUES OF A HAMILTONIAN - Systems and methods for employing macroscopic resonant tunneling operations in quantum processors are described. New modes of use for quantum processor architectures employ probe qubits to determine energy eigenvalues of a problem Hamiltonian through macroscopic resonant tunneling operations. A dedicated probe qubit design that may be added to quantum processor architectures is also described. The dedicated probe qubit enables improved performance of macroscopic resonant tunneling operations and, consequently, improved performance of the new modes of use described. | 05-12-2016 |
