20100078753 | Flow Sensor and Method of Fabrication - A method for forming a flow sensor having self-supported heat-carrying elements is disclosed. Self-supported heat-carrying elements are capable of operating with higher thermal efficiency, enabling lower power consumption and higher sensitivity, due to a lack of heat loss into a supporting membrane. Self-supported heat-carrying elements facilitate wider operating temperature range and compatibility with harsh media. | 04-01-2010 |
20100254560 | MICROFABRICATED MICROPHONE - The present invention provides a microfabricated microphone that can mitigate negative effects caused by residual stress in its sensing diaphragm. In particular, a center-supported diaphragm is provided to allow residual stress to relax through the radial expansion or contraction of the diaphragm. The diaphragm is suspended by an anchor that is attached to a supporting beam. The supporting beam is situated in between one or more sections of a back-plate electrode. The supporting beam is mechanically and electrically separated from the back-plate electrode. Various mechanical dimensions of the aforementioned components are also disclosed to optimize performance of a microfabricated microphone in different operational conditions. Further, a method and system for fabricating a microfabricated microphone with a center-supported diaphragm is also disclosed. | 10-07-2010 |
20110137209 | MICROPHONE ARRAYS FOR LISTENING TO INTERNAL ORGANS OF THE BODY - An electronic device is provided for receiving sounds from a body. A microphone array receives the sounds. An analysis system optionally provides for directional control, such as by providing virtual focusing and beam steering. Body sounds are preferably de-convolved. In certain embodiments, a plurality of buffer structures are located in cavities in a patch adjacent the microphones to provide for improved sound pick-up. In certain embodiments, at least two of microphones are spaced at least 2 centimeters apart. Preferably, wireless transmission circuitry sends information relating to the sounds in the body, and optionally receives information, such as control or status information. Target selection and acquisition systems provide for the effective capture of multiple sounds from the body, even when the device is adhered to the body by the user, that is, not a skilled physician. | 06-09-2011 |
20110264178 | Probe for Neural Stimulation - A neural probe for stimulating neural tissue is disclosed. The probe comprises a three-dimensional arrangement of individually addressable electrodes. As a result, embodiments of the present invention can steer stimulative electric current through a wide range of paths through neighboring neural tissue. This enables specific targeting of neural selected neural tissue. In addition, embodiments of the present invention provide increased tolerance to probe misplacement or movement after insertion. Further, embodiments of the present invention enable changes in the neural tissue being stimulated without requiring additional surgical procedures. | 10-27-2011 |
20110306859 | MULTIPURPOSE, MODULAR PLATFORM FOR MOBILE MEDICAL INSTRUMENTATION - A system provides for mobile medical instrumentation for use with a body. The system includes a primary wireless communication device, such as a cell phone or tablet computer, and one or more cradles. The cradles provide an interface to the body which provides for input of signals from the body, and optionally, therapeutic outputs to the body. The cradle and the primary wireless communication device may be releasably joined together so as to form a unitary structure when contacting the body. Alternately, the cradle may interface with the body, and communicate wirelessly to the primary wireless communication device. A cradle adapted to provide for a portable electrocardiogram includes a plurality of electrodes adapted for contact or non-contact sensing of the body. In the preferred embodiment, three electrodes are arranged in a triangular arrangement, most preferably a Einthoven triangular arrangement, with the distance between electrodes being 4 centimeters or less. | 12-15-2011 |

A control circuitry is coupled to the transmission system and the receiver system. The patch is preferably provided with a wireless communication system to permit external control and or communication. Applications range from diagnostics and monitoring, to rehabilitation and wound healing. | 03-15-2012 |
20120204652 | PRESSURE SENSOR STRUCTURE AND ASSOCIATED METHOD OF MAKING A PRESSURE SENSOR - A pressure sensor can include a diaphragm plate of an electrically conductive material, the diaphragm plate including substantially planar opposed first and second surfaces. A layer of a dielectric material can be provided at the first surface of the diaphragm plate along a periphery thereof such that a flexion region of the first surface is substantially free of the dielectric material. The dielectric layer can be configured to engage a fixed structure within a housing to support the flexion region as to enable deflection thereof relative to the fixed structure that changes an electrical characteristic of the pressure sensor in response to application of force at the second surface of the diaphragm plate. | 08-16-2012 |
20120232398 | WIRELESS FETAL MONITORING SYSTEM - A wireless fetal and maternal monitoring system includes a fetal sensor unit adapted to receive signals indicative of a fetal heartbeat, the sensor optionally utilizing a Doppler ultrasound sensor. A short-range transmission unit sends the signals indicative of fetal heartbeat to a gateway unit, either directly or via an auxiliary communications unit, in which case the electrical coupling between the short-range transmission unit and the auxiliary communications unit is via a wired connection. The system includes a contraction actuator actuatable upon a maternal uterine contraction, which optionally is a EMG sensor. A gateway device provides for data visualization and data securitization. The gateway device provides for remote transmission of information through a data communication network. A server adapted to receive the information from the gateway device serves to store and process the data, and an interface system to permits remote patient monitoring. | 09-13-2012 |
