摘要:
A joint synchronizer and decoder that implements two decision aided processes, which are referred to as “decision aided candidate selection” and “decision aided synchronization and decoding.” Decision aided candidate selection may be used to select a carrier frequency offset by selecting among a number of candidates for this parameter based on an indication of decoding success. Decision aided synchronization and decoding may be used for phase tracking based on an indication of decoding success. Although these joint synchronizing and decoding techniques may be implemented together, they may also be implemented independently. The joint synchronizer and decoder may be implemented within a return channel receiver in a DVB-RCS system using turbo coding and quadrature phase shift key (QPSK) data modulation.

A zipper-type wound closer attachable to the skin around a skin opening and zipped closed to pull the skin opening closed. The wound closer includes two elongated connecting strips whose feet are pre-coated with adhesive and attached to the skin around the skin opening. The edges of the wound are trimmed flush with the interior sides of connecting strips, and the strips are then zipped together by moving a slider along the connecting strips to join the strips together like a familiar zipper. The wound zipper forms a continuous, toothless seam to prevent seepage of fluid through the seam. By holding the freshly trimmed edges of the skin opening together immobile in a clean, firm, closely aligned connection, the wound closer recreates the conditions under which scar-free healing of the skin can occur naturally; useful for repairing wounds and removing existing scars.

A processor (10) controls the operation of the device and preferably provides for a plurality of operational algorithms or modes. A program switch (18) allows the user to select which algorithm will be used. The processor drives an inverter (12), which drives a power amplifier or bridge (13). The output of the bridge 13 is connected to one or more transducers 16. When the user presses the switch (19A), the processor begins the algorithm. One or more of the transducers are placed on the patient's body in the area to be treated. The algorithms provide for lower-frequency and higher-frequency sweeps, which the transducers convert to microvibrations which, in turn, massage not only the muscles and the larger blood vessels, but also the smaller blood vessels and capillaries, and provide for improved blood circulation in the affected area, thereby relieving pain and enhancing recovery.

A portable, hands-free and user friendly breast pump for facilitating breast-feeding, incorporates a dome-shaped housing having a servomotor mechanism; a hat-shaped flange having a chamber portion, a brim portion and an outlet, the chamber portion being formed so as to be placed over a nipple on a breast so as to define a chamber between the flange and the breast, and the brim portion being formed to surround the nipple and thereby form a suction seal therebetween; and a one-way venting element formed to operatively communicate with the chamber so as to vent pumped milk from the chamber via the outlet. The housing, the flange and the venting element are connected into an integral device held against the breast and underneath clothing so as to keep the integral device hidden. Breast milk is collected via a plastic collection bag that connects directly with the pump underneath clothing such that the milk is isolated from any contaminants in the air and may be easily stored immediately after being collected.
摘要:
A wiper-type phase shifter with a cantilever shoe that ensures that the electrical contact on the wiper arm remains in electrical communication with the transmission trace located on the antenna backplane without relying to an element, such as a spring-loaded set screw, that passes through the backplane. The cantilever shoe thus provides a wiper hold-down mechanism without requiring holes or slots through the backplane, which could allow rain or other elements to get inside the antenna enclosure. A dual-polarization antenna that includes a wiper-type phase shifter for each polarization. The wiper arms define gear portions that engage each other, which allows a single actuator, typically located on the rear of the backplane opposite the location of the wiper arms, to drive both wiper arms in a coordinated manner. The antenna is suitable for use as a wireless base station antenna.

摘要:
A personal health card that includes a smartcard with an RFID device that automatically reports certain RFID response information when illuminated by an interrogation signal from an RFID reader, such as an authorized first responder interrogation device issued to police, fire, lifeguard, or EMT personnel. The RFID response information may be as minimal as a visible or audible “ping” response displayed or played on the RFID interrogator indicating that a personal health card has been interrogated. If multiple cards respond to the interrogator, the RFID interrogator can be used to select among the responding cards so that the operator can investigate one card at a time. A characteristic of the response from a selected card may change in response to the strength of the signal received from the card to help the operator locate and recover a desired card. For example, the volume of an audible “ping” at the interrogator may become louder or more frequent as the interrogation response from the card becomes stronger to provide a “homing device” for physically locating a particular card. This feature is very helpful when emergency responses are attempting to locate personal health cards at the scene of an accident or other incident.

A global customer satisfaction system includes point-of-sale customer feedback terminals for receiving in-store customer feedback including satisfaction ratings and other customer feedback regarding participating vendors as the customer pays for purchases. The system also includes post-sale customer feedback terminals for receiving more detailed customer feedback regarding the vendors from members after the sales have been completed. The system also includes an aggregation and dissemination system for combining the ratings received form customers into global customer satisfaction ratings for participating vendors, and disseminating the customer satisfaction information through customer satisfaction qualified directories, which are organized or searchable by geographical, type of product or service offered by the participating vendors, and other factors.
摘要:
A tag-mediated review system for electronic content that ranks content based upon several ascertainable factors, including the implicit engagement with the content by users (typically online viewers); the expertise and success in the topical domain by reviewers; and the review activity of users or viewers. The system extends implicit metrics to tracking of user interaction including the receipt of video and audio content over the web. Document ranking is mediated by tags that identify the subject matter addressed by an associated document as the ranking mediators for computing content quality scores values for user and reviewer activity. The tag-mediated content quality scores, which are content quality scores for the subject matter area identified by the associated tags, can be exposed to end-users and used directly or indirectly to complement search engine retrieval algorithms.
摘要:
A very narrow band multipoint communication system suitable for use in an automatic meter reading (AMR) system having a communication protocol that divides each main channel of a frequency or digital code hopping system into multiple sub-channels and applies frequency division multiplexing among the sub-channels. Each sub-channel exhibits a very narrow band characteristic that allows gain increase to increase the transmission range of the meters. In addition, frequency division multiplexing among the sub-channels greatly increases the number of meters that can communicate on each main channel. The data collection device demodulates and decodes the multiplexed meter signals at an intermediate frequency with electronic circuitry. The resulting very narrow band AMR system exhibits greater transmission range, greater bandwidth and can accommodate a much larger number of meters per data collection device in comparison to a conventional narrow band AMR system.
