23698 results about "Miniaturization" patented technology

Miniaturization (Br.Eng.: Miniaturisation) is the trend to manufacture ever smaller mechanical, optical and electronic products and devices. Examples include miniaturization of mobile phones, computers and vehicle engine downsizing. In electronics, Moore's law, which was named after Intel co-founder Gordon Moore, predicted that the number of transistors on an integrated circuit for minimum component cost doubles every 18 months. This enables processors to be built in smaller sizes.

Implantable medical device incorporating integrated circuit notch filters

Implantable medical devices (IMDs) having sense amplifiers for sensing physiologic signals and parameters, RF telemetry capabilities for uplink transmitting patient data and downlink receiving programming and interrogation commands to and from an external programmer or other medical device are disclosed. At least one IC chip and discrete components have a volume and dimensions that are optimally minimized to reduce its volumetric form factor. Miniaturization techniques include forming notch filters of MEMS structures or forming discrete circuit notch filters by one or more of: (1) IC fabricating inductors into one or more IC chips mounted to the RF module substrate; (2) mounting each IC chip into a well of the RF module substrate and using short bonding wires to electrically connect bond pads of the RF module substrate and the IC chip; and (3) surface mounting discrete capacitors over IC chips to reduce space taken up on the RF module substrate. The IC fabricated inductors are preferably fabricated as planar spiral wound conductive traces formed of high conductive metals to reduce trace height and width while maintaining low resistance, thereby reducing parasitic capacitances between adjacent trace side walls and with a ground plane of the IC chip. The spiral winding preferably is square or rectangular, but having truncated turns to eliminate 90° angles that cause point-to-point parasitic capacitances. The planar spiral wound conductive traces are further preferably suspended over the ground plane of the IC chip substrate by micromachining underlying substrate material away to thereby reduce parasitic capacitances.

Self-powered resonant leadless pacemaker

InactiveUS20070293904A1Increases natural velocity and acceleration of heart muscleExtended durationElectrotherapyCardiac cycleCardiac pacemaker electrode
A self-powered medical device, for example a pacemaker uses the variations of blood pressure inside the heart or a major artery to create a mechanical resonance in an electromagnetic or piezoelectric generator. The resonance extends the time power is generated during the cardiac cycle. The pressure variations compress a bellows carrying the resonant generator. The inside of the bellows may be evacuated to a partial or full vacuum, and a spring restores the bellows to the desired equilibrium point, acting against the blood pressure. The current pulses are stored in a capacitor. Eliminating the battery allows dramatic miniaturization of the medical device to the point it can be implanted at the point of desired stimulation via a catheter.

Method and apparatus for high-performance compact volumetric antenna with pattern control

InactiveUS20150102972A1Increase intrinsic inductive reactanceOptimize the magnetic fieldAntenna feed intermediatesElectronPhysics
A wide-bandwidth antenna with antenna pattern control includes a radiator and a feed. The radiator includes two or more volumetric radiating elements. The feed includes two or more feed units, the feed units configured to provide wave signals to the volumetric radiating elements. The feed units provide an independent signal for each radiating element. The wave signals can be fed out of phase to each other. Depending on the dielectric filler inside the volume of the antenna and the phase shift between feeds, the pattern can be modified electronically leading to pattern control. The radiating elements are spaced at a distance at least one order of magnitude smaller than half of an operational wavelength of the antenna. At least one electrically conductive element of the antenna is capable of conducting a current that generates a magnetic field. The magnetic field lowers the total reactance of the antenna, thereby resulting in enhanced performance of the antenna in terms of bandwidth, gain, and pattern control. The volumetric design allows miniaturization of the antenna.

Self-powered leadless pacemaker

A self-powered pacemaker uses the variations of blood pressure inside the heart or a major artery to create a periodic change in the magnetic flux inside a coil. The pressure variations compress a bellows carrying a magnet moving inside a coil. The inside of the bellows is evacuated to a partial or full vacuum, and a spring restores the bellows to the desired equilibrium point, acting against the blood pressure. The current pulses are stored in a capacitor. Eliminating the battery allows dramatic miniaturization of the pacemaker to the point it can be implanted at the point of desired stimulation via a catheter. The invention includes means of compensating for atmospheric pressure changes.

Apparatus and method for locating, tracking, controlling and recognizing tagged objects using active RFID technology.

The present invention is directed to a miniaturized apparatus to locate, track, recognize and control objects using miniature RF circuits that are programmed as an active tag or as one of several embodiments of a controller, including one small enough to be incorporated into a personal object, like a ring. In its simplest embodiment, a portable or wearable controller communicates wirelessly with a tag secured to a surface, analogously to a car remote—push button, receive a signal from tag or back at the controller, to locate tagged object. In more complex forms, the tag can be integrated into objects or connected to a network. One controller can manage a plurality of tags. The basic platform of tag and controller can be built up to create a sophisticated area control with environmental sensors, inventory functions, tracking individuals and allowing or denying access, operating objects like doors and lights, and creating supporting ambient security with checks and balances between tags and controllers on people and their possessions, such as baggage at an airport. Arrays of tag or controllers extend the wireless range to accommodate large structures and areas. This novel system is self-contained, with a low power protocol to give long battery life time and does not require internet or GPS to perform its functions.

Design-manufacturing interface via a unified model

Subtleties of advanced fabrication processes and nano-scale phenomena associated with integrated circuit miniaturization have exposed the insufficiencies of design rules. Such inadequacies have adverse impact on all parts of the integrated circuit creation flow where design rules are used. In addition, segregation of the various layout data modification steps required for deep sub-micrometer manufacturing are resulting in slack and inefficiencies. This invention describes methods to improve integrated circuit creation via the use of a unified model of fabrication processes and circuit elements that can complement or replace design rules. By capturing the interdependence among fabrication processes and circuit elements, the unified model enables efficient layout generation, resulting in better integrated circuits.
