A medical equipment includes an optical connector that detachably connects a plug to a receptacle provided in an equipment main body to optically connect a plug-side optical fiber fixed to the plug and a receptacle-side optical fiber fixed to the receptacle. The plug and the receptacle have plural engagement pairs each having a protrusion that protrudes in an insertion direction of the plug and an engagement part that is adapted to be engaged with the protrusion. Engagement beginning positions of the engagement pairs where the protrusions and the engagement parts begin to engage are different along the insertion direction. Each engagement pair has a narrower engagement gap between the protrusion and the engagement part than that between the protrusion and the engagement part of any pair which begin to engage earlier as the plug is inserted than the protrusion and the engagement part of each engagement pair.

A step detecting apparatus and method in a personal navigator where acceleration signals in at least two directions are acquired from an accelerometer sensor, as a pedestrian moves. Variances of the acceleration signals are calculated and summed. The variance sum is compared with a threshold. If the variance sum is greater than the threshold, it is determined that a detected step is a walking step. If the variance sum is less than the threshold, it is determined that the detected step is a mark-time step.

In a coil arrangement for nuclear magnetic resonance comprising a main coil (13), a shielding coil (14), and at least one correction coil (41), the function of which consists in forming a magnetic field gradient with eddy current properties which are as good as possible, the main coil (13) and the shielding coil (14) are electrically connected in series with the correction coil (41). The deviations of the residual field from the desired design generated by production tolerances are thereby modified by the correction coil in such a fashion that the long-lasting eddy currents are suppressed. This either reduces the waiting time that must lapse after a gradient pulse before a predetermined field homogeneity is achieved or e.g. the deviations from the desired field are minimized in imaging applications.

A computer-implemented method for extracting information from a document, for example an official document, is disclosed. The method comprises acquiring an input image comprising a document portion; performing image segmentation on the input image to form a binary input image that distinguishes the document portion from the remaining portion of the input image; estimating a first image transform to align the binary input image to a binary template image, using the first image transform on the input image to form an intermediate image; estimating a second image transform to align the intermediate image to a template image; using the second image transform on the intermediate image to form an output image; and extracting a field from the output image using a predetermined field of the template image.

A printed IC board has a multilayer printed wiring board and one or more bare IC chips. The multilayer printed wiring board has insulation layers made of PTFE, and wiring patterns formed on the insulation layers which are stacked to make a lamination structure. Electrode parts as parts of the wiring patterns are electrically connected to the bare IC chip. A copper member which serves as a reinforcing member is laid in a region formed in the insulation layers other than a first insulation layer. the region is formed directly below the electrode parts. The region is formed in a direction Z along a thickness of the stacked insulation layers. The region formed directly below the electrode parts in the insulation layers in the insulation layers other than the first insulation layer has a higher rigidity than the insulation layers.

This disclosure concerns the identification of qualifying consumer offers. In one example, the identification is performed by a server. The server first receives an electronic graphical representation of purchase information and extracts from the graphical representation text data elements relating to the purchase. The server then matches the text data elements to criteria of one or more consumer offers to identify qualifying offers, such that predetermined criteria of the qualifying offer is successfully matched to the data elements. Finally, the server sends or displays to the consumer information relating to the qualifying consumer offers. Identifying offers that a purchase qualifies for is automatic, and more efficient and less costly to deliver. Commonly used receipts can be used as purchase information and there is no requirement for the receipt to contain any particular notation. This makes the method agnostic to the retailer.

Compositions and methods of producing mammalian cell populations that include a high proportion of pancreatic beta cells are described herein. Such cell populations are useful for treatment of diabetes. Also provided are materials and methods for the direct differentiation of stem cells, such as embryonic stem cells, into functional pancreatic beta cells. The disclosure provides the benefit of direct differentiation, which results in the production of functional pancreatic beta cells efficiently and at low cost.

Load-measuring transducers utilizing induced-voltage measurement techniques are described. The wiring patterns of such transducers can be configured to reduce interference errors due to wiring patterns thereof.

An upsetting method capable of eliminating a correction step by preventing occurrence of quench distortion is provided. The method includes the step of preparing an upsetting apparatus 10 equipped with a forming die 11 and a guide 20 having an insertion hole 21 for securing a diameter expansion scheduled portion 2 of the bar-shaped raw material 1 in a buckling preventing state and a punch 30. The diameter expansion scheduled portion 2 of the raw material 1 in a heated state is disposed in the insertion hole 21 of the guide 20 in a heated state, and the tip end portion of the guide 20 is disposed in the cavity 12 of the forming die 11 adjusted in temperature so as to be below a temperature of the raw material 1, and the raw material is secured to the securing portion 13 of the forming die 11. With this state, the guide 20 is moved in a direction opposite to a moving direction 37 of the punch 30 while axially pressurizing the diameter expansion scheduled portion 2 of the raw material 1 by moving the punch 30, to thereby expand the diameter expansion scheduled portion 2 of the raw material 1 exposed between a tip end portion of the guide 20 and the securing portion 13 of the forming die 11 within the cavity 12 of the forming die 11.

An imaging system includes an imaging station, an actuator for driving a medium roller for controllably displacing the medium along a media transport path, and a controller assembly. The controller assembly includes a sensor device for generating a position signal and a processor for processing the position signal. The actuator is actuated in response to an actuation command from the controller assembly, which actuation command is derivable from a feedback component and a feedforward component. The feedback component is based on a position error. The processor is further arranged for determining a time dependent status parameter, which status parameter represents a status of the medium on the medium roller. The processor is further arranged for deriving an actuation command estimate based on the status parameter, and wherein the feedforward component includes the actuation command estimate.

The present invention provides oligonucleotide primers, compositions, and kits containing the same for rapid identification of bacterial bioagents and populations of bioagents which are members of the Staphylococcus bacterial genus by amplification of a segment of bioagent nucleic acid followed by molecular mass analysis.

The presence of defects in a wiring pattern is checked by a visual method, by image processing, or the like, and when a defect is detected, information such as the position, coordinates, and size of the defect is confirmed, the type of defect is confirmed, and a processing method and processing conditions are set in accordance with the defect type and conditions (step S1). Shorting defects are corrected based on the processing method and processing conditions that have been set and the defect information that has been confirmed (step S2). Subsequently, disconnection defects are corrected based on the set processing method and processing conditions and the confirmed defect information (step S3). Upon completion of these correction operations, a determination is made as to whether the defects have been corrected (step S4). By this means, the operating time for wiring correction can be shortened, and automation facilitated.
