摘要:
An electronic device, like a mobile telephone, has a first section and a second section. The first section and second section are coupled together by a mechanical connection, for example a hinge, swivel or sliding connector. Electronic components in the first section are coupled to electronic components in the second section by conductors capable of transferring power between the first and second sections. A current detector is capable of detecting currents, like surface currents, while a controller is responsive to the current detector. A plurality of reactive elements, like capacitors for example, are coupled to a plurality of switches such that the controller may selectively couple any of the plurality of reactive elements to the conductors by actuating a corresponding switch. When the current detector detects a current in excess of a predetermined threshold, the controller alters the complex impedance between the first and second sections by actuating one or more of the switches, thereby coupling one or more of the reactive elements to the conductors.

An energy density diversity antenna (EDA) has a least a pair of antenna elements, whose feeding points are connected to outputs of a hybrid coupler configured such that a sum and a difference signal may exist at the feed points of the antenna elements. First reactive elements are respectively inserted in the antenna elements proximal the respective feed points. The antenna elements are joined at a point distal from the feed points by a second reactive element, and a third reactive element is coupled between feed lines coupled to the feed points at a location between the feed points and the outputs of the hybrid coupler.

A vestibular implant comprising a stimulation unit to generate electric stimuli and deliver to electrode arrays is disclosed. The stimulation unit generates electric stimuli in response to a user input or continuously generates electrical stimuli. The electrode arrays comprise electrodes and are adapted for placement within a semicircular canal of an ear. The electric stimuli is delivered from the stimulation unit to the electrode so that the electrodes apply electric stimuli. A predetermined electric stimulus is applied to restore spontaneous vestibular activity during a Meniere's attack. A continuous, unmodulated electric stimulus is applied to suppress the symptoms of unilateral loss of vestibular function. Additionally, the electrodes record electrically evoked compound action potentials (eCAP). An appropriate location for the placement of the electrode array is determined based on the recorded eCAP.

Described are selectable notch filter circuits comprising at least two different notch filter capabilities, each of which is capable of filtering interference of a designated fundamental frequency and a second harmonic of the designated fundamental frequency from an electrical signal. Each of the notch filters of the circuit is specific for real time filtering of a different designated fundamental frequency and a second harmonic thereof from digitized signal data input into the circuit. The filtering capability of each filter is dictated by control logic, which uses a coefficient set specific for the designated fundamental frequency and harmonics thereof. By using different coefficient sets, different designated fundamental frequencies and at least their second harmonic frequencies can be filtered from digitized signal data input into the circuit. Because the control logic can utilize at a given time any one (or, if desired, none) of the coefficient sets available to it, different interfering fundamental frequencies can be filtered, if and as necessary, from digitized input signal data collected over time at a substantially equivalent sampling rate. Also described are devices including one or more such selectable notch filter circuits, including implantable medical devices such as implantable cardioverter/defibrillators, as well as methods of using such devices.

Methods and apparatus to control electro-mechanical brakes are disclosed. A disclosed example method of controlling a brake actuator comprises receiving a value representative of a velocity of a piston associated with the brake actuator relative to a pressure plate mounted on a wheel, and determining a control input for the brake actuator based on the velocity value.
摘要:
The cooling system for the nozzle edges includes a chamber containing a cooling medium. First and second elongated plenums are disposed along opposite side edges of each platform. Inlet passages communicate cooling medium from the chamber into each plenum. Outlet passages from each plenum terminate in outlet holes in the side edges of the platform to cool the gap between adjacent nozzle segments. Passageways communicate with each plenum and terminate in film cooling holes to film cool platform surfaces. In each plenum, the inlet passages are not in direct line-of-sight flow communication with the outlet passages and passageways.

Inventive systems and methods for remotely controlling infrared controlled devices by using addressed radio frequency control signals. Radio frequency signals propagate through most obstructions to infrared control signals. Augmenting each control signal with an address allows for great selectivity in an environment with several transmitters and receivers.

摘要:
A remote control for learning a macro routine of optical signals is provided. An optical receiver is arranged to receive optical signals from one or more original equipment remote controls. The optical receiver outputs electrical signals. A microprocessor receives the electrical signals from the optical receiver. A memory device stores the electrical signals from the optical receiver. An operator interface is electrically coupled to the microprocessor. The operator interface receives operator input to designate a macro routine of operator-selectable optical signals from the original equipment remote control. The microprocessor causes the electrical signals from the optical receiver that correspond to the operator-selectable optical signals from the original equipment remote control to be associated with the designated macro routine and stored in the memory device. Electrical signals associated with a macro designation are retrieved from the memory device and electrically coupled to an optical transmitter.
