Title: Apparatus and method for measuring drop size in an intravenous drip chamber
Inventor: BROWN HOUSTON
IPC: A61M5/168
Filed: 2001-11-20
Abstract: A capacitive-based apparatus (10) for measuring the volume of a fluid drop (30) passing through an intravenous drip chamber (12). The apparatus includes a capacitor (16) comprising two parallel plates (42) that are a fixed distance apart and are positioned such that the fluid flow path in the drip chamber is between them. The fluid drop moving through the drip chamber between the plates causes the capacitance of the plates to change. This change in capacitance is measured and from it, the volume of the drop is calculated. The volumes of a series of drops are integrated to provide a measured rate of flow through the drip chamber. This measured rate of flow is compared to the programmed rate of flow and the difference is used to adjust a flow control device to obtain the desired rate of flow.
Patent CA-2429735-A1 (CA)
Inventor: LEANING ANTHONY RICHARD
IPC: H03M7/30
Filed: 2001-11-19
Abstract: A system for transmitting audio signals over a telecommunications link generates the signals as two or more alternative feeds, for example at different data rates. The two feeds are encoded using coding methods having a frame structure with different frame lengths. To facilitate switching between the two, the input signal is notionally divided into temporal portions and each is coded by taking it, plus enough of the next (or preceding) portion to make up a whole number of frames, and encoding it, whereby the encoded portions overlap-at least for one of the feeds. The overlap is lost upon decoding by discarding duplicate material.
