In order to detect movements of objects and / or living beings in a radio range, which enables easily with a minimum of hardware complexity an automated movement detection based on a Single-Sensor, it is proposed to: Collect as input data for the movement detection based on received radio signals of an intended or unintended communication between a transmitting radio terminal being mobile or fixed and a receiving local fixed radio device in the radio range a set of “Channel State Information”-values, determine a change in the received radio signals, which are derived from the facts that the movement influences the transmitted radio signal in the radio range based on the collected CSI-values by the indication of a statistical parameter value, and assess on the basis of the statistical parameter value a “chaos index” value until the “chaos index” value in accordance with a threshold check provides a reliable statement.

The disposable unit also includes at least one flexible membrane portion attached onto said base portion and forming a top of said reservoir cavity and a top of said fluid channel and a tubing connected to said base portion at said cannula port, said tubing in fluid communication with said reservoir cavity.

In a time division multiple access wireless communication system, a wireless radio station performs a timing error compensation method. The wireless radio station receives messages including a synchronisation pattern. The wireless radio station adopts a power down mode between reception of messages, and accumulates a timing error representing an accumulated difference between expected times of arrival of the synchronisation patterns and actual times of arrival of the synchronisation patterns, during a predetermined time interval between reception of successive messages and before an expected reception of a next message. Thereafter, the wireless radio station at least substantially undoes the accumulated timing error, before the expected reception of the next message such that the timing error is compensated before the expected reception of the next message.

A method for magnetizing a wellbore tubular is disclosed. The method includes magnetizing a wellbore tubular at three or more discrete locations on the tubular. In exemplary embodiments the magnetized wellbore tubular includes at least one pair of opposing magnetic poles located between longitudinally opposed ends of the tubular. Wellbore tubulars magnetized in accordance with this invention may be coupled to one another to provide a magnetic profile about a section of a casing string. Passive ranging measurements of the magnetic field about the casing string may be utilized to survey and guide drilling of a twin well. Such an approach advantageously obviates the need for simultaneous access to both wells.

The invention provides a voice-helping intelligent glasses system aiming at the totally-blind visual handicapped. The voice-helping intelligent glasses system comprises a spectacle frame, a high-definition camera acquisition device, sensors used for detecting the external environment, and a data processing center. The voice-helping intelligent glasses system can acquire an actual scene in real time and send the actual scene to a server-side, the server-side carries out real-time processing and modeling to the actual scene by means of an image processing algorithm. the surrounding environment of the blind person can be identified, voice indication is sent to the blind person through a Bluetooth bone-conduction earphone, and vibrations of different strengths can be given to the blind person according to the distances of barriers. By means of a machine learning algorithm, the system automatically learn, and objects are stored in a database. At the same time, the voice-helping intelligent glasses system can identify and acquire characters on books and newspapers, and can convert the characters into voices, and the characters can be read to the blind person through the earphone, and the voice-helping intelligent glasses system can help the blind person read without difficulty. The voice-helping intelligent glasses system can be connected with the Internet through WiFi, and the blind person can surf the Internet in a voice manner, and can be connected with a mobile phone through Bluetooth. The voice-helping intelligent glasses system aiming at the totally-blind visual handicapped is small in size, and is portable and practical, and can be well accepted by blind people.

A frame for attachment to an article is provided, the frame comprising a crosspiece and an arm, the crosspiece being coupled to the arm and comprising pegs, the pegs being structured and arranged for insertion within an article opening. The arm comprises a distal end for insertion within a second opening of the article. The frame comprises transport members, such as wheels or sliding members, adapted to permit the article and frame to be moved when the frame is attached to the article. The frame may be adapted for attachment to a portable cooler comprising a foot opening and a handle opening, the pegs being adapted for insertion within the foot opening, the arm adapted for insertion within the handle opening. The crosspiece and arm may be adjustable in length. One or more frames may be attached to the portable cooler.

The invention is an aircraft having an inflatable wing connected to a base unit, with the inflatable wing inflated with a lifting gas such as helium. The inflatable wing has a series of cell structures, and may be configured with ballonets to selectively introduce and expel outside air within the inflatable wing to vary the buoyancy and / or airfoil properties of the inflatable wing. The aircraft is particularly useful at low speeds and in thin atmospheres (such as at high Earth altitudes and on Mars), and can be used for interplanetary missions to explore planetary bodies, such as moons and planets, having atmospheres.

This relates to an improved delivery system for accurately loading and controlling the delivery of flowable material to a patient. Particularly, the system may be used in the injection of hard tissue implant materials such as PMMA under pressures up to about 4000 psi. The system includes an applicator with a first column having an implant material introduction section adapted to provide for effective loading of the implant material and a second column housing a piston. The introduction section has a larger size than that of a vessel section or bore in which the requisite pressure seal between the piston and bore wall is formed. The first column may include an introduction section flared open to an included larger funnel-like opening or a separate funnel may be used that interfaces with the introduction section to facilitate the introduction of implant material. Handles on the first and second columns to be turned relative to each other to advance the columns toward each other may be provided for manual actuation of the applicator to drive implant material through a cannula and deliver implant material to a desired site.

A system and method for use in managing and preparing for scheduled procedures that are characterized as being interdependent and variable. The disclosed method enables schedule risk management and provides a look-ahead capability along with process diagnostics to isolate specific assets and tasks that can be managed to reduce schedule risk. The method facilitates review of upcoming tasks by the process stakeholders for education as to where the schedule risks reside and in an emulation mode for review and improved scheduling going forward. Clinical workflow is integrated such that process stakeholders and assets are directed in such a way as to keep on, reduce delay risk or recover the schedule.

The fixator includes a telescopically adjustable strut having first and second ends and a strut axis, and first and second compound joints. The first compound joint is coupled to the first end of the strut and to a first bone clamp, and includes a first gear mechanism controlling linear and rotational motion of the first bone clamp relative to first and second axes while the first bone clamp is engaged with the first bone portion. The first and second axes are generally orthogonal to one another and to the strut axis. The second compound joint is coupled to the second end of the strut and to a second bone clamp and includes a second gear mechanism controlling linear and rotational adjustment of the second bone clamp. The first compound movable joints can rotate about the strut axis.
