Abstract:

An illustrative cochlear implant system includes an electrode lead having an array of electrodes, a cochlear implant coupled with the electrode lead and configured to be implanted within a recipient together with the electrode lead, and a processing unit communicatively coupled to the cochlear implant. The processing unit is configured to direct the cochlear implant to apply stimulation to the recipient by way of the array of electrodes. The processing unit is further configured to detect, by way of one or more electrodes included in the array of electrodes, a cortical potential produced by the recipient. Based on the detected cortical potential, the processing unit is configured to determine a fitting parameter associated with the cochlear implant system. Corresponding systems and methods are also disclosed.

Abstract:

An illustrative system includes a stimulation device configured to apply stimulation to a recipient, a sensing device configured to detect a physiological condition of the recipient, and a processing unit communicatively coupled to the stimulation device and the sensing device. The processing unit determines a stimulation strategy that is customized to the recipient and includes stimulation frames and stimulation gaps. The processing unit then directs the stimulation device to apply the stimulation to the recipient in accordance with the stimulation strategy by applying the stimulation only during time that corresponds to the stimulation frames. The processing unit also directs the sensing device to detect the physiological condition of the recipient in accordance with the stimulation strategy by detecting only during time that corresponds to the stimulation gaps. Based on the detected physiological condition, the processing unit performs an action. Corresponding systems, methods, and apparatuses are also disclosed.

Abstract:

A reservoir for containing a fluid includes a cylindrical wall sized to engage a shaft bored into ground, a bottom end cap fixed to a lower end of the cylindrical wall and a top end cap fixed to an upper end of the cylindrical wall. The top end cap is concave such that the top end cap extends below a top end of the cylindrical wall. The bottom end cap, the top end cap, and the cylindrical wall define a subterranean chamber. A plug made of a composite material is on the top end cap, with a lower face disposed on the concave top end cap and a peripheral face engaging the shaft. At least one pressure port extends downwardly into the shaft and through the plug and the top end cap, defining a fluid path to the subterranean chamber.

International Classification:

H04R 25/00

Abstract:

A binaural hearing system (“system”) enhances and/or preserves interaural level differences between first and second signals. The system includes first and second audio detectors associated with first and second ears of a user, respectively. The audio detectors detect an audio signal presented to the user and generate the first and second signals to represent the audio signal as detected at the first and second ears, respectively. The system also includes a first sound processor that receives the first signal from the first audio detector and the second signal from a second sound processor via a communication link with the second sound processor. The first sound processor generates a directional signal representative of a spatial filtering of the audio signal detected at the first ear according to an end-fire directional polar pattern and presents an output signal representative of the directional signal to the user at the first ear.

International Classification:

F28D 20/00
B65G 5/00

Abstract:

Thermochemical energy storage (TCES) for concentrating solar power (CSP) systems provides higher energy density than sensible energy storage systems. An ammonia-based TCES system dissociates endothermically into hydrogen and nitrogen. The stored energy is released when supercritical hydrogen and nitrogen react exothermically to synthesize ammonia. Prior ammonia synthesis systems are unable to produce temperatures consistent with modern power blocks requiring a working fluid, for example steam or carbon dioxide, to be heated to greater than 600 C., for example about 650 C. An ammonia synthesis system heats steam from, for example 350 C. to 650 C. under pressure of about 26 MPa. The hydrogen and nitrogen are preheated with a flow of supercritical fluid prior to the synthesis step to provide reaction rates sufficient to heat power block working fluid to the desired temperature.

Abstract:

A method of adding informative content to an electronic knowledge base includes generating a plurality of database tables from a plurality of websites, each database table based on a corresponding website, and individually processing each database table to identify potentially informative content from each database table. The method further includes identifying as informative content, the potentially informative content that is included in a first predetermined number of the database tables of the plurality of database tables, the first predetermined number being greater than one, and adding the informative content to the electronic knowledge base.

International Classification:

Abstract:

An implantable blood pump includes motor control circuitry and power electronics circuitry integrated within the implantable pump body. The motor control circuitry and power electronics circuitry is configured to energize and control motor windings to rotate the pump rotor and impeller. Additional control circuitry and power electronics circuitry may be integrated within the pump housing to energize and control magnetic bearings of a magnetic levitation pump. A percutaneous cable coupled between the implantable blood pump and an extracorporeal monitor includes a reduced number of leads to provide power and control signals to the implantable blood pump. Wireless communication between the extracorporeal monitor and the integrated power electronics and control circuitry facilitates the use of a percutaneous cable with as few as two leads for providing power to the implantable pump.
