Title: Voice suppression of vagal stimulation
Inventor: BAKER ROSS G JR
IPC: A61N1/08
Filed: 1992-06-12
Granted: 2002-01-22
Abstract: In conjunction with a medical device for stimulating the vagus nerve of a patient to modulate the electrical activity thereof as part of a prescribed therapy, apparatus is provided to selectively suppress the stimulation while the patient is speaking, to avoid undesirable modulation of the voice. The suppression apparatus includes a speech sensor and discriminator, to detect speech by the patient white avoiding false detection attributable to sounds other than speech. The suppression of nerve stimula-tion is ceased after a preset time interval regardless of continued detection of speech, to assure that beneficial therapy is not undu-ly inhibited in favor of mere cosmetic considerations or in the presence of prolonged false defections. In the preferred embodi-ment, the discriminator selectively varies the sensitivity of the suppression apparatus to speech by the patient to enhance its selectivity over sounds attributable to other sources. The apparatus comprises an electrode array (40), an electrical lead (42), a generator (10), and a wand (55).

Abstract: An improved photoionization ion mobility spectrometer is disclosed which utilizes a flashlamp (12) as the source for ioni-zation. A gas sample is introduced via a carrier gas into an ionization chamber (30) which is part of the spectrometer cell. Ioniz-able molecules contained in the injected gas sample are ionized by the ultraviolet light emitted from the flashlamp. The ionized molecules are attracted by an electrostatic drift field into a drift chamber (20) and travel therethrough against the flow of a drift gas counter-current thereto until they are captured by a collector located in the drift chamber opposite to the ionization chamber. A dopant with an effective ionization potential lower than the photon energy of the emitted light can be introduced into the ioni-zation chamber to further improve the sensitivity and specificity.

Granted: 2007-10-16
Abstract: A method of fracturing a subterranean formation in a well bore is shown in which a gellable fracturing fluid is first formed by blending together an aqueous fluid, a hydratable polymer, a suitable cross-linking agent for cross-linking the hydratable polymer to form a polymer gel and an enzyme breaker. The cross-linked polymer gel is pumped into the well bore under sufficient pressure to fracture the surrounding formation. The enzyme breaker is allowed to degrade the cross-linked polymer with time to reduce the viscosity of the fluid so that the fluid can be pumped from the formation back to the well surface. The particular enzyme breaker utilized has an activity in the temperature range from about 60-300°F and at a pH range from about 2.0 to 11.0 and is effective to attack only specific linkages in the cross-linked polymer gel.
