Abstract:
A method includes depositing a thin film on a first surface of a first substrate and moving a second surface of a second substrate into contact with the thin film such that the thin film is located between the first and second surfaces. The method further includes generating electromagnetic (EM) radiation of a first wavelength, the first wavelength selected such that the thin film absorbs EM radiation at the first wavelength. Additionally, the method includes directing the EM radiation through one of the first and second substrates and onto a region of the thin film until the first and second substrates are fused in the region.
Abstract:
A medical system includes a sensor location module, a first module, and a second module. The sensor location module (132) determines a location of a magnetic field sensor (110) within a magnetic field. The first module (160) determines an acceleration of the magnetic field sensor. The second module (138) indicates a modified location of the magnetic field sensor in an image of a medical patient based on the acceleration and one or more previously determined locations.
Abstract:
Techniques are described for directly bonding different substrates together. In some examples, a technique includes placing a first surface of a first substrate in contact with a second surface of a second substrate to directly bond the first substrate to the second substrate at a contact location. The contact location is defined where at least a portion of the first surface of the first substrate contacts at least a portion of the second surface of the second substrate. The technique may also include directing a laser beam on at least a portion of the contact location to strengthen the direct bond between the first substrate and the second substrate. In this manner, a direct bond may be heated with localized laser energy to strengthen the direct bond. Localized laser energy may create a strong direct bond while minimizing thermal defects in regions proximate the direct bond.

Abstract:
A hair dryer assembly provides an additional amount of heat to the air exiting the dryer (2). The assembly includes a hand-held hair dryer (2) and a diffuser (22) attachable to the air outlet end (18) of the hair dryer (2). The diffuser comprises a heating element (28) to add heat directly to a user's hair or to air passing out of the hair dryer (2) and through the diffuser (22). This additional measure of heat is used to facilitate drying and/or styling of hair.
Abstract:
An implantable capacitive pressure sensor apparatus and method for making such an apparatus includes a first pressure sensor portion and a second pressure sensor portion. The first pressure sensor portion includes a diaphragm electrode connectable to ground (e.g., the diaphragm electrode being positioned in close proximity to the body when implanted therein such that the diaphragm electrode is deformable in response to pressure applied thereto by the body). The second pressure sensor portion includes a signal electrode (e.g., wherein the first pressure sensor portion and the second pressure sensor portion are coupled such that a gap is provided between the diaphragm electrode and the signal electrode) and an insulator material. The signal electrode is provided on and in direct contact with the insulator material to electrically isolate the signal electrode such that parasitic capacitance effects on the signal electrode are reduced.

Media-exposed interconnects for transducer modules are disclosed. The transducers may be sensing transducers, actuating transducers, IC-only transducers, or combinations thereof, or other suitable transducers. The transducers may be used in connection with implantable medical devices and may be exposed to various media, such as body fluids. The media-exposed interconnects for transducer modules may allow transducers to communicate electrically with other components, such as implantable medical devices.

Abstract:
An implantable medical device (IMD) is disclosed. The !MD includes a first substrate having a front side and a backside. A first via is formed in the front side, the via extending from a bottom point in the front side to a first height located at a surface of the front side. A first conductive pad is formed in the first via, the first conductive pad having an exposed top surface lower than first height. A second substrate is coupled to the first substrate, the second substrate having a second via formed in the front side, the via extending from a bottom point in the front side to a second height located at a surface of the front side. A second conductive pad is formed in the second via, the second conductive pad having an exposed top surface lower than second height. The coupled substrates are heated until a portion of one or both conductive pads refiow, dewet, agglomerate, and merge to form an interconnect, hermetic seal, or both depending on the requirements of the device.
