A power source comprises at least one photovoltaic cell arranged adjacent a plurality of self-luminous microspheres containing a radioactive material such as tritium and phosphor particles. Photons generated from the phosphor particles strike the photovoltaic array which converts the light to electrical energy. The self-luminous microspheres can be arranged adjacent the photovoltaic array using a binder material. The inventive power source provides a portable, safe, and long lasting battery which is adaptable for a wide range of applications requiring a reliable power source.

An ingestible image scanning pill captures high resolution images of the GI tract as it passes through. Images communicated externally have exact location determination. Image processing software discards duplicate information and stitches images together, line scan by line scan, to replicate a complete GI tract as if it were stretched out in a straight line. A fully linear image is displayed to a medical professional as if the GI tract had been stretched in a straight line, cut open, laid flat out on a bench for viewing—all without making any incisions in a live patient.

A radio frequency identification (RFID) architecture is described. RFID tags are interrogated by a reader, which may be located in a network of readers. The reader transmits symbols to the tags. Tags respond to the interrogations with symbols that each represent one or more bits of data. An RFID tag includes an antenna pad, a receiver, a state machine, and a modulator. The receiver is coupled to the antenna pad. The receiver receives a symbol from the antenna pad and outputs a received signal. The state machine is configured to determine a response symbol from the received signal and an operating state of the tag. The modulator is coupled to the antenna pad. The modulator is configured to backscatter modulate the received symbol with the response symbol. The modulator is configured to output the backscatter modulated symbol to the antenna pad.

A method and system for device assembly and a method, system, and apparatus for transfer of dies using a pin plate are described herein. A die plate is received having dies. The body of the die plate has a plurality of holes extending therethrough. Each die covers a corresponding hole on a first surface of the die plate. The die plate is positioned to be closely adjacent to the web of substrates. The punching device has a plurality of punching members extending from an outer surface. The punching device is planar or alternatively cylindrical. The punching device is applied to a second surface of the die plate to cause a set of the punching members to extend through a set of holes in the die plate, causing dies to be transferred from the die plate to one or more destination substrates or other surfaces.

The present invention relates to ultrasound imaging on a capsule endoscope platform. It relates to the generation of a focused ultrasound acoustic signal and the receiving of echo signals from the wall of a body lumen with an array of acoustic transducers wrapped around the circumference of the capsule. It relates to sending the generated echo image signals to receiver devices attached or worn on the body. It relates to the generation of 360° overlapping sidewall ultrasound scans of a body lumen, and image processing techniques to assemble these scans into a high resolution continuous ultrasound image. Finally, it relates to the manufacture and assembly of such an ultrasound scanning capsule endoscope (USCE). The concept is extendable to conventional endoscopes and catheters.
摘要:
Devices and systems to interrogate radio frequency identification (RFID) tags are described. Compact and inexpensive interrogation devices are realized by implementing integrated circuit chip-based RFID reader and antenna on a common substrate. The small form-factor devices may be used for quick and easy installation of RFID reader network. In an aspect, the device may be incorporated into hand-held mobile devices in order to serve as a mobile reader. In another aspect, the device may be installed as a shelf-reader or a rack-reader, displaying product-specific information on a display screen. In a further aspect, the device may comprise an appliance, whose operation can be tailored according to instructions received specific to a RFID-tagged item.
摘要:
An embodiment of the present invention provides a system including a plurality of radio frequency identification (RFID) tags and a reader. Each RFID tag of the plurality of RFID tags backscatter transmits a signal. In one embodiment, the reader includes a plurality of antennas and a signal processor. In another embodiment, the system includes a signal processor and a plurality of readers each including an antenna. In either embodiment, each antenna receives a plurality of signals corresponding to the backscatter transmitted signals. The signal processor combines the received plurality of signals to produce an output signal.

A method, system, and apparatus for transferring integrated circuit dies is described. A die receptacle structure has a first surface. The first surface has a plurality of cells formed therein. Each cell is configured to contain an integrated circuit die. A bottom surface of each cell is configured to attract dies having a first material thereon. Example forces that can be used to attract dies into cells include a magnetic force, a chemical force, and an electrostatic force.

A method, system, and apparatus for transfer of dies using a die plate having die cavities is described herein. The die plate has a planar body. The body has a plurality of cells or cavities which are open at the first surface of the body. Each cell has a hole extending from the bottom surface of the cell to a second surface of the body. A wafer or support structure can be positioned to be closely adjacent to each other. A suction can be applied to the second surface of the die plate so that a plurality of dies can be transferred into a plurality of cells of the die plate. The dies can subsequently be transferred from the die plate having die cavities to one or more destination substrates or surfaces, by a punching mechanism.
