Abstract: A holding and moving device includes a support foot, a bearing arm secured pivotably onto the support foot to form a useful load side section and a weight-side section, a first pivot arm connected to the useful load side section of the bearing arm for attachment of a useful load and/or holding device for a useful load, and a second pivot arm connected to the weight-side section of the bearing arm for attachment of a balance weight. The bearing arm and the first and second pivot arms are connected to one another such that the alignment of the first and second pivot arms are essentially parallel to one another in each position. The second pivot arm and/or the weight-side section are designed such that the weight of the first pivot arm and/or of the useful load side section is balanced in each position of the holding and moving device.

Abstract: The present invention provides methods and apparatuses for approximating a ground state or a Gibbs state of a k-local Hamiltonian using a quantum computer system. The procedure begins by providing a set of local generalised measurements corresponding to the terms of the k-local Hamiltonian. A set of data qudits is initialised into an initial state and a local generalised measurement is subsequently performed to perturb a subset of the data qudits from an initial state to a perturbed state. The perturbation is accepted or rejected based on a measurement outcome of the local generalised measurement. The perturbation and accept/reject steps are repeated unless or until a stopping condition is met. The result of the procedure is to provably drive the encoded Hamiltonian toward or even into a ground state or a Gibbs state, a useful starting point in many quantum algorithms, such as those relating to materials simulation.

Abstract: A radar system with transmitting circuitry to generate a frequency-modulated output that includes an up-chirp and a down-chirp. The radar system includes receiving circuitry configured to: receive radar returns from a target, calculate a first frequency difference based on the up-chirps and calculate a second frequency difference based on the down-chirps.

The system also calculates a fine but ambiguous estimate of the Doppler frequency shift by using multiple chirps either from the same triangular waveform or from a separate waveform. The system calculates an unambiguous and accurate Doppler frequency shift estimate for the target by combining the unambiguous but coarse estimate of the Doppler frequency shift and the fine but ambiguous estimate of the Doppler frequency shift.

Abstract: A hydraulic system has a fluid path which connects two system components fluidically to one another and which comprises a hydraulic hose. It is known to form a fluid path between two components of a hydraulic system, for example between a pump and a control block, by a single hydraulic hose which is designed in accordance with the maximum volume flow and the maximum pressure. A hydraulic hose for large volume flows and high pressures is disproportionately expensive relative to a hydraulic hose for smaller volume flows and, on account of its larger internal and external diameters, has a larger minimum bending radius than a hydraulic hose for smaller volume flows. In order to provide a cost-effective and compact structure, a hydraulic system according to the disclosure has the fluid path formed by at least two hydraulic hoses arranged fluidically parallel to one another.

Then when resuming the audio content, a time interval between the first date timestamp and a current date timestamp may be determined. A resumption timestamp in the audio content may be determined based on the time interval being within a certain time range. After resuming playback, a feedback input may be determined. The feedback may be used in adjusting the resumption settings. The adjusted resumption settings may be used in subsequent resumption of the same or different content.
