摘要:
A robot machining with a flexible manipulator has an end effector which may either hold the tool to perform the machining or the work piece to be machined. A signal representative of a force applied by said tool to said work piece is used to control either the relative motion between the tool and the work piece to give a controlled material removal rate (CMRR) or the relative position between the tool or the work piece to provide deformation compensation or both CMRR and deformation compensation. A force sensor provides the signal for deformation compensation. For CMRR the signal may be obtained from either a force sensor or the current flowing in the motor of the robot's spindle. The force sensor can be mounted either on the robot or together with either the tool or work piece adjacent to the robot.

The disclosed system and method provide for the automatic assessment of the presence/severity of the sleep problem and its exact nature. The assessment is based on qualitative information about sleep patterns, insomnia-related factors and daytime consequences, as well as quantitative information about sleep patterns measured by a sensor. By combining the different sources of information (subjective as well as objective data), the diagnosis gives more insight into the nature of the sleep problem and is therefore more accurate. Furthermore, the disclosed system may be used to select specific components of the system that are medically relevant to the individual and therefore create a personalized program. The system teaches a selection of self-management skills that could help the individual to better cope with sleep disturbances and target those factors that maintain the problem or make it worse by a particular individual.

Distributing information over a network is disclosed. Nodes are grouped into regions. Preferred nodes are designated. A source of content to be delivered to a preferred node using a preferred algorithm is indicated to at least one preferred node. At least one common node is assigned the preferred node as a relay of information.
摘要:
Provided are an apparatus, method, and medium for generating a panoramic image. In the apparatus, a previously captured image and a currently captured image are projected onto a predetermined curved surface so as to form a first mapping image and a second mapping image, respectively. Movement values in predetermined directions are calculated for maximizing a color similarity between overlapped sections of the first and second mapping images. A panoramic image is generated using the first and second mapping images and the calculated movement values. Therefore, overlapped sections of neighboring images can be precisely superposed and aligned when a panoramic image is generated using a series of images.
摘要:
The present invention relates to the field of biomarkers and, more specifically, to biomarkers useful in diagnosing aggressive prostate cancer. In specific embodiments, a method for diagnosing aggressive prostate cancer in a patient comprises (a) measuring the levels of one or more biomarkers in a sample collected from the patient; and (b) comparing the levels of the one or more biomarkers with predefined levels of the same biomarkers that correlate to a patient having aggressive prostate cancer and predefined levels of the same biomarkers that correlate to a patient not having aggressive prostate cancer, wherein a correlation to one of the predefined levels provides the diagnosis. In a specific embodiment, the one or more biomarkers may comprise cathepsin-L (CTSL), periostin, microfibrillar-associated protein 4 (MFAP4), collagen XII, neprilysin, clusterin, neutrophil gelatinase associated lipocalin (NGAL), epithelial cell activating molecule (EpCAM), prostate specific antigen (PSA), membrane metallo-endopeptidase (MME) and asporin (ASPN).

A variety of systems and methods are described which enable quantitative information to be extracted regarding automated procedures, including those performed at a high speed that may require a user input, without having to interrupt the procedure. In addition, these systems and methods serve to provide information on one or more parameters of the automated procedure, whereby they may be modified, if required, to improve the automated procedure or the results from such a procedure. The systems and methods provided are especially useful in automated hair transplantation procedures.
