Title: Uterine cervix dilation, effacement, and consistency monitoring system
Inventor: TOMER DAVID
IPC: A61B5/03
Filed: 1998-09-30
Abstract: A system and method for monitoring uterine cervical dilation, effacement, and consistency during labor. A probe (100) comprising a linear caliper (138, 140) and a flexible membrane (128) is applied to the uterine cervix (126) and is loaded by a constant closing force generated by a hydraulic piston mechanism (144). The flexible membrane (128) assumes the contour of the opening of the uterine cervix (126), a fiber-optic sensor (130) on the probe (100) measures the curvature of the membrane (128), and a processor (104) calculates the degree of cervical effacement from the displacement data. The caliper closing force is transiently altered, and the resultant caliper arm displacement value is compared with a baseline displacement value so as to calculate a descriptor of cervical consistency. Cervical dilation, effacement and consistency data is displayed in real time, and compared with stored normal values.

Title: Gain control amplifier, variable gain and automatic gain control amplifiers including differential circuit transistors and current splitter
Inventor: POPESCU PETRE
IPC: H03G3/30
Filed: 1999-12-16
Abstract: A gain control amplifier includes an input diffential circuit having a pair of transistors, the emitters of which are coupled via a pair of emitter resistors. The input differential circuit includes a current sink for providing an operating current. With variation of the operating current, the gain control amplifier's gain is varied. Two emitter coupled differential amplifiers are connected to the input diffential circuit having a current sink. A current flowing in the transistors of the emitter coupled differential amplifier and the input differential circuit is split by an additional emitter coupled differential circuit having a current sink. A current splitting factor is controlled in response to the voltage difference between the collectors of the two transistors of the two emitter coupled differential amplifiers. Since the relatively small currents flow in the emitter resistors, noise caused thereby is relatively low. Thus, it provides a wide input dynamic range with low noise. The gain control amplifier is used in a variable gain amplifier and an automatic gain control amplifier.
Patent CA-2321434-A1 (CA)
Title: Liner hanger
Inventor: BENNETT RODNEY D
IPC: E21B43/10
Filed: 2000-09-29
Abstract: A liner hanger assembly has a slip actuation system which is locked for run-in. A piston assembly bolts onto the mandrel in a sealable manner to actuate a mechanical lock. Upon release of the lock, a plurality of springs actuate a sleeve which is in turn attached to the slips to move them relative to their slip seats. The slip seats are preferably mounted to the mandrel without welding and have longitudinal spaces for mud or cement flow therebetween. Load is distributed from each slip through its slip seat into the mandrel without interaction from an adjacent slip or slip seat. A rupture disk ensures that a predetermined pressure is built up before the piston can actuate to defeat the lock. The lock can come in a variety of configurations. One of which is a sliding sleeve over a dog and another is a yoke over a split ring which, when shifted, allows the split ring to expand, thus unlocking the parts. The slips can also be configured to allow flow of mud or cement behind them, thus reducing the resistance to flow of such materials.
