In addition, further functionalities that are traditionally in separate units can be integrated into the system and efficiently performed by the same electronics, such as battery management and thermal management.

A care system and associated methods are provided for alleviating patient pain, anxiety and discomfort associated with medical or surgical procedures. The care system facilitates a procedural clinician's safely and efficaciously providing sedation and analgesia and in some measure, amnesia to a patient by providing a responsiveness monitoring system which monitors the responsiveness of the patient and generates a value representing the level of patient responsiveness. In further aspects of the invention, the responsiveness monitoring system is an automated system which includes patient query and response devices. Additional embodiments of the system and methods are directed to alleviating patient pain or discomfort while enabling safe drug delivery (automated, clinician-controlled or patient-controlled) in correlation with the monitoring of patient health conditions.

This invention discloses a system and method to operate a doubly-fed induction generator (DFIG) as a grid-friendly virtual synchronous generator (VSG). It comprises a DFIG modeled as a virtual differential gear that links a rotor shaft driven by a prime mover, a virtual stator shaft coupled with a virtual synchronous generator G and a virtual slip shaft coupled with a virtual synchronous motor M, and a variable frequency drive that behaves as a virtual synchronous motor-generator set to regulate the speed of the virtual synchronous motor M so that the speed of the virtual stator shaft, i.e., the speed of the virtual synchronous generator G, is within a narrow band around the grid frequency even when the rotor shah: speed changes. As a result, a grid-connected DFIG can be controlled to behave like a virtual synchronous generator without using a PLL.

A method and automated apparatus for locating and selecting a colony of microorganisms on a culture dish and subjecting the obtained sample to a plurality of downstream tests including a test to identify the microorganism and a test to identify the susceptibility of the microorganism to antibiotics. The method includes the automated steps of locating and selecting a colony of microorganisms on a culture dish; obtaining a sample of the selected colony of microorganisms; preparing a suspension of a sample of microorganisms automatically by submerging the pick tool with the sample in a suspension, after which the pick tool is vibrated in at least the vertical direction to release the sample from the pick tool in the suspension. The turbidity of the suspension is monitored to ensure that the concentration of microorganism in suspension is sufficient so that the suspension is used a source for sample for both identification and antibiotic susceptibility of the microorganisms in the sample. The apparatus and system optionally provides for downstream processing of samples prepared for antibiotic susceptibility testing (AST). Such apparatus includes further processing after inoculation of an AST panel for the AST test. Such further processing includes capping and transferring inoculated panels to AST instrument.

A cap that is to be fitted to a printed circuit board, which has a conductive pad on the front side of the rectangular board thereof and which is to be connected to the connector. The cap is formed into a bag and is shaped into a wedge that gets thinner towards the front, and the cap has a window for exposing the conductive pad of the printed circuit board. A low insertion force connector that connects a printed circuit board having conductive pads on the front side of the rectangular board thereof. This low insertion force connector comprises a connector body having at least a pair of contacts that contact the conductive pads and clamp the printed circuit board, a slider that carries the printed circuit board and advances to and retreats from the contact, and a guide that is provided at the front end of the slider and is formed into a wedge-shape, which gets thinner towards the front. The present invention reduces the insertion force of the printed circuit board, enhances the connection workability, and eliminates damages or the like to the contacts and the conductive pad to enhance the reliability. The present invention provides a connector that is also effective in countermeasures against heat and electromagnetic waves.

An optical dynamic gain equalization filter (DGEF) comprises a planar arrangement of preferably “perfectly sampled” (or alternatively oversampled) waveguide grating routers (WGR's) connected by individual optical paths each containing a Mach-Zehnder interferometer operated in a push-pull fashion so that a positive phase change in one interferometer arm and a corresponding negative phase change in the other interferometer arm produces a desired change in attenuation while, at the same time, the overall phase of the optical signals after passing through the Mach-Zehnder interferometer is kept constant with respect to the adjacent paths. Alternatively, the above-described arrangement is effectively “cut in half”, and its size effectively also reduced accordingly, using a mirror placed at the midpoint of the device and an appropriate circulator to separate the input and output optical signals.

A magnetic core extends in a longitudinal direction and contains at least one stacking of sheets consisting of magnetic material and stacked in a direction of stacking perpendicular to the longitudinal direction, at least one plate of heat-conducting material, presenting first and second opposing faces, and at least one cooling tube positioned in contact with the said first face of the plate in which a heat-bearing fluid is designed to circulate. The plate extends in a plane parallel to the longitudinal direction and to the direction of stacking, its second face being positioned in thermal contact with the sheets in the stacking.

A method of sequentially performing concentration and amplification of nucleic acid in a single micro chamber includes: introducing a nucleic acid-containing sample and a solution including a kosmotropic salt to a micro chamber having a hydrophilic interior surface to concentrate the nucleic acid by binding the nucleic acid on the interior surface of the micro chamber; and performing a polymerase chain reaction (PCR) by adding a PCR mixture to the chamber. Since the nucleic acid is reversibly bound to the interior surface of the micro chamber, PCR yield is higher compared with a surface of aluminum oxide in which irreversible binding occurs. In addition, all processes are sequentially performed in a single micro chamber so that the number of samples, consumables, time, and labor for treatment and analysis can be reduced, detection sensitivity can be improved, and risk of sample cross contamination significantly reduced without sample loss by eliminating transporting of the sample. A complete automated system for concentration and amplification of nucleic acid is thus readily provided.

A wireless module includes a flex substrate, an antenna integrated in the flex substrate and electrically connected to a signal layer and a ground layer of the flex substrate, a first rigid substrate stacked on one side of the flex substrate remote from the antenna, and a communication unit mounted on the first rigid substrate and electrically connected to the signal layer. Thus, the flex substrate and the first rigid substrate are laminated into a Rigid-Flex board. Further, the signal layer and the ground layer are continuously arranged in the same flex substrate, It will be helpful in decreasing the uncertainty and loss of RF signal transmission path, reducing component costs, facilitating optimization of the antenna and reducing the module size.

A LPF extracts DC component of a current detection value of an inverter input current. A subtracting section 4 calculates a difference between a current command value and the DC component of the current detection value. A current controller 5 produces two-phase PWM signals Sa and Sb complementary to each other, from the current difference. Further, an integrating circuit 7 integrates output terminal voltages Vu, Vv and Vw of the inverter to convert the output terminal voltages Vu, Vv and Vw into a magnetic-flux information Φu, Φv and Φw. A logic conversion section 8 converts the magnetic-flux information Φu, Φv and Φw into 120-degree conduction patterns S1′-S6′ to output the 120-degree conduction patterns S1′-S6′. Then, a logic circuit section 9 executes a logic synthesis between the PWM signals Sa and Sb and the 120-degree conduction patterns S1′-S6′ to output gate signals S1-S6.
