摘要:
A switching system interface (304) including one or more network interfaces for terminating digital transmission facilities; one or more interfaces (403, 404) for coupling to line/trunk frames (212) of a digital switch; a time-slot assignment means for connecting time slots to those of the line/trunk frames; and a call processing means for coordinating call setup and teardown between the DLC local terminal and the line/trunk frames, and for managing the time-slot assignment means to complete calls.
摘要:
A method and apparatus for inserting a small diameter continuous hydraulic conduit or capillary tube down a well bore is presented. The methods and apparatus allow either the injection of chemicals to enhance production of oil and gas, or to provide a conduit for production up through the small diameter tubing in marginal wells, into a hanger below a well valve to permit its removal from below the valveif the valve should be required to be closed and its reinsertion without pulling the tubing from the well bore.

The invention relates to apparatus (1) for obviating deterioration of a product in a container (2), such as a "beg-in-box" for dispensing of say wine, comprising means (3) adapted for absorption of agents deleterious to the wine, particularly ambient oxygen. In the embodiment, this means (3) comprises a socket of oxygen-absorbing material in a compartment (5) of a body (7) of a tap (6).
摘要:
The present invention provides for a method for inducing myocardial cell proliferation, as well as for myocardial cell cultures produced by this method. The method is based on the discovery that adult human myocardial cells may be induced to proliferate in culture by exposure to a platelet freeze/thaw extract. In a preferred embodiment the myocardial cells are adult human atrial myocardial cells.
摘要:
Cette invention concerne un procédé permettant d'induire la prolifération des cellules myocardiques, et des cultures de cellules myocardiques produites à l'aide de ce procédé qui se fonde sur la découverte qu'on peut inciter des cellules myocardiques d'un individu adulte à proliférer dans un milieu de culture en les exposant à un extrait plaquettaire congelé puis décongelé. Dans un mode d'exécution préféré les cellules myocardiques sont des cellules myocardiques auriculaires d'un individu adulte.
摘要:
A boat (10) having a plurality of separable water-tight transverse sections (14, 16, 17, 18) combined end-to-end to form a hull assembly (12). A pair of tendons (34) extends longitudinally along the hull assembly and each tendon is attached to the bow and stern sections. The tendons follow geodesic lines along opposite sides of the longitudinal centre line (B) of the hull below the waterline and below the neutral axis (A').
摘要:
Discrete-dipole methods and systems for applications to complementary metamaterials are disclosed. According to an aspect, a method includes identifying a discrete dipole interaction matrix for a plurality of discrete dipoles corresponding to a plurality of scattering elements of a surface scattering antenna.
摘要:
An output signal device and method that provides the operator force feedback similar to a pilot control joystick. These force feedback regions include free play, dead-band start of modulation, modulation, fore-warning bumper and hold near max angle. This output signal device may also vary the fore-warning feel and hold positions to be at any angle. This output signal device uses force sensing as the signal and has force slope changes used as auto-calibration of the output signal. This improves signal accuracy and provides a service prognostic signal. The prognostic signal may be used to activate redundant sensor. The variable force feedback may improve operation on rough terrain. The force feedback, may allow more productive operating positions to be learned. This enables productivity and other important job site criteria such as fuel usage to be optimized by interactive communication with this output signal device.
摘要:
An apparatus is described that selectively absorbs electromagnetic radiation. The apparatus includes a conducting surface, a dielectric layer formed on the conducting surface, and a plurality of conducting particles distributed on the dielectric layer. The dielectric layer can be formed from a material and a thickness selected to yield a specific absorption spectrum. Alternatively, the thickness or dielectric value of the material can change in response to an external stimulus, thereby changing the absorption spectrum.

A bi-polar battery has a positive electrode unit, a negative electrode unit, at least one bi-polar electrode unit stacked therebetween, an electrolyte layer separating each adjacent electrode unit, and a gasket positioned about each electrolyte layer for creating a seal about the electrolyte layer in conjunction with the electrode units adjacent thereto. The bi-polar battery also includes a wrapper for maintaining the seals created by the gaskets.
