Patent NO-20052423-D0 (NO)
Inventor: CHEN ERNEST C
IPC: H04L27/20
Filed: 2005-05-19
Abstract: Methods and apparatuses for maximizing power and spectral efficiencies in a wireless communication system are disclosed. The invention is particularly useful for layered modulation applications because power levels for such applications a re relatively high. A layered modulation signal comprises an upper and a lower layer signal that interfere with each other within the same frequency band such th at the upper layer signal can be demodulated directly from the layered modulation signal, and the lower layer signal can be demodulated after subtracting the first layer signal from the layered modulation signal. The invention applies one or more of the following four signal schemes in a communication signal including varying th e symbol rate (rather than the code rate), reducing or eliminating the guard band, reducing excess signal bandwidth and employing layered modulation within the guard band of the legacy signal.

Title: Resource access proxy for efficient access to sensor resources
Filed: 2010-06-23
Abstract: A resource access proxy provides a facility in a network to enable a resource user to gain access to a resource. The resource access proxy receives a request and establishes a secure session with a requesting resource user, so that authorisation for access can be established. The resource access proxy also establishes a secure session with the requested resource, and forwards the resource users request to the resource. If the resource authorises the request, it returns the result to the resource user via the resource access proxy. On so establishing access, a security token can be returned to the requesting resource user, along with an attribute token to identify the resource user in the context of the network established with the resource, so that the resource user can establish direct communication with the resource for future requests in a particular session.

Title: Method for handling zeotropic refrigerant mixtures
Filed: 2011-02-16
Abstract: A method for preparing a ternary or higher zeotropic refrigerant mixture comprising components of different volatilities is described. The method comprises: mixing together the less volatile components of the mixture in a pre-blending process; and separately adding the most volatile component to the pre-blended mixture by pressure or mass flow control so that the desired initial liquid composition is attained. The liquid zeotropic refrigerant mixture that is prepared may be transferred from a container in which it is held to another container or to a piece of equipment that is to use the refrigerant mixture. This method comprises the steps of: removing at least a portion of the prepared liquid zeotropic refrigerant mixture from a container in which it is held; charging the liquid zeotropic refrigerant mixture that is removed to another container or to a piece of equipment in which it is to be used; and adding at least the most volatile component of the refrigerant mixture to the holding container to compensate for the removal of liquid refrigerant mixture therefrom.

Inventor: KOPPL GEORG
IPC: H01H39/00
Filed: 1982-12-28
Granted: 1986-04-03
Abstract: To provide a high-voltage switch which can switch off in a very short time, namely in a half-period, rapid severing of the isolating screws (36) is utilized, and the high-voltage switch is designed so that the switch-off and switch-on device contains at least one isolating screw (36) by means of which a prestressed rod (28) connected to the movable contact of the high-voltage switch can be released.

Granted: 1986-02-27
Abstract: The present invention relates to an arrangement for detachably securing together the side-pieces (1) and the shelves (2) of a shelving structure, made of wood or a comparable material. The arrangement comprises hook-like fasteners, each of which comprises an insert peg (5), which is arranged to be inserted into an insert hole (3) formed in a side-piece (1), and a binding peg (7) which extends at right angles to the insert peg (5) and which is intended to be removeably inserted into a binding hole (11) formed in the shelf (2), to permit the shelves to be readily moved from one level to another in the shelving structure. There has long been sought a technically and economically advantageous solution to the problem of producing a shelving structure or cabinet structure which can be quickly assembled in a simple fashion while using the simplest of components preferably solely smooth, sheet-like components having no outwardly projecting parts. The present invention affords such a solution, in that the insert peg (5) is provided with a plate-like projection (9), or a plurality of axially spaced plate-like projections, located in a plane substantially at right angles to the insert peg (5). The insert hole (3) is of non-round cross-section, and the arrangement of the projection or projections (9) is such that when an insert peg is inserted into a non-round insert hole (3) and rotated through about 90 DEG  in the opening, the projections penetrate the wall of the insert hole, to prevent withdrawal of the insert peg (5) therefrom.
