Abstract: A bubble-actuated valve with latching may be utilized to regulate fluid flow in any number of applications, including the controlled delivery of drugs or other bioactive agents or compounds. The bubble-actuated valve utilizes the bubble to move a solid object that does the actual blocking of the flow channel to regulate the flow of liquid through the valve. The bubble-actuated valve may also include a latching mechanism. One such latching mechanism utilizes the capillary attraction between the solid object and neighboring walls to latch the solid object in place when the valve is not actuated.

Title: Method and system for determining data transfer margins for network connections
Inventor: PYTHOUD FREDERIC
IPC: H04M11/00
Filed: 2001-11-15
Granted: 2012-09-04
Abstract: The invention relates to a method and a system for determining data transfer margins and/or bit rates for network connections, the physical length (13) of a network connection (12) to be determined between an emitter (10) and a receiver (11) being known. A power spectrum is measured according to the transfer frequency for possible modem types (101, 102, 103, 104) by means of a power measuring device (20). The damping and thus the effective signal strength is determined for different physical lengths (13) and cable core thicknesses (141, 142, 143, 144) of a network connection (12). Furthermore, the noise level is determined at least according to crosstalk parameters, the number of interference sources and equaliser factors based on the power spectrum. The data transfer margins are determined for different data transfer modulations and/or modulation codings for a pre-defined bit rate, on the basis of the effective signal strengths and on the corresponding noise levels, by means of a Gaussian transformation module (31). Said data transfer margins are corrected by means of a correction factor containing the mean deviation of the stored data transfer margin in relation to the effective data transfer margin. The data transfer margin for the respective network connection (12) is then determined on the basis of the stored effective data transfer margin with the known physical length (13) of the network connection (12) to be determined between the emitter (10) and the receiver (11).
