Abstract: A method for determining a link path and an unoccupied wavelength channel on the optical transmission links of said link path, for setting up a connection by means of at least one first and second network nodes within a transparent optical transmission system is provided. According to one embodiment of the method, a respective link weighting is determined for the wavelength channels of an optical transmission link, said weighting depending on the optical transmission link and on the considered wavelength channel. A connection cost value is also generated for each link path, which is available for the connection setup, and for the corresponding wavelength channel by evaluation of the at lest one link weighting and, for the connection setup, the link path with the corresponding wavelength channel, which has the minimum connection cost value, is selected.

Abstract: Disclosed is a transparent optical transmission system comprising a plurality of network nodes that are interconnected via optical transmission links. Several optical connection paths in said transparent optical transmission system are established, maintained and disconnected from a first optical network node to a second optical network load by means of signaling messages via at least one transmission link which is provided with optical transmission channels. A probability of occupancy is determined for each optical transmission channel per transmission link in order to improve the network load information in the network nodes.

Abstract: An electronic apparatus comprising: a housing; an infrared filter window supported by the housing; and an infrared transceiver mounted in the housing so that infrared light emitted by the infrared transceiver is focused in the vicinity of the infrared window, and radiates from the infrared filter window in an approximately 30 degree illumination cone.

Abstract: The present description relates to a method comprising transmitting acoustic waves through a material of alternating electrical polarity to create a magnetic field and detecting the magnetic field.

Abstract: A method and apparatus for acquiring pulse oximetry and electrocardiogram signals from an appendage of a patient. The apparatus can include a substrate that can be attached to the appendage of the patient, an emitter coupled to the substrate, a detector coupled to the substrate, and an electrode coupled to the substrate. The apparatus can generate a blood oxygen saturation output signal based on radiation received by the detector. The apparatus can also generate a reference or non-reference electrocardiogram signal. The apparatus can include a neural-muscular transmission device.
