Granted: 2002-01-01
Abstract: A clamping mechanism for mounting a circuit condition monitoring device to electrical cables of various diameters includes a core member comprising a plurality of laminations arranged in a generally rectangular configuration.  A spring spanning the core member is anchored at one end to the core at a point near the housing of the monitoring device and at the other end is attached to a bridging member affixed at the opposite end of the core near the housing.  This allows the spring to expand less as it transverses the bridge in order to accommodate different power cable diameters.

Title: Anisotropic texture mapping using silhouette/footprint analysis in a computer image generation system
Inventor: LEE HARRY CHARLES
IPC: G06F3/14
Filed: 1998-11-19
Granted: 2010-12-14
Abstract: Anisotropically mapping of texture information to each pixel required for display of each of plural. polygons forming each scene on a CIG display in a computational efficient manner, uses the footprint of each transformed pixel silhouette, as mapped from image space into the texture array, to determine an anisotropic texture space area having both a related length and a related width, in which complete texels and texels fractions are covered by that pixel footprint. A set of un-normalized line equations characterizing a particular pixel footprint is used to determine whether each texel or subtexel in the vicinity of that pixel footprint is either enclosed or avoided by (i.e. inside or outside of) that projected pixel footprint.

Title: Handling of forwarded calls
Inventor: VERKAMA MARKKU
IPC: H04M3/54
Filed: 1998-12-11
Granted: 2006-10-10
Abstract: This invention proposes a new charging principle according to which the roaming leg is paid entirely by the party who forwards the call to a mobile subscriber. In an exemplary embodiment, the call is first routed to the exchange of subscriber B, who has forwarded his calls. After determining that the call is to be forwarded to a mobile subscriber C, the exchange routes the call to the gateway mobile switching center GMSC capable of making interrogations to the home location register of subscriber C. When the charging record for the call is generated, the called subscriber B is charged for the leg between the GMSC and subscriber C. Thus, subscriber C does thus not have to pay for calls addressed to subscriber B. To minimize the call costs to subscriber B, as direct a route as possible is preferably used on the leg between the GMSC and subscriber C.

Abstract: An apparatus and method to obtain a high Q, narrowband active filter with hi gh gain suitable for an integrated circuit implementation. The high Q is achiev ed via active feedback with an amplitude control loop. The frequency control of  the active filter is achieved by means of a frequency locked loop. Both control loops compare the thermal noise of the active filter itself to volta ge and frequency references to achieve the stable operating point. Control loop s are normally slow relative to the transmitted data, hence avoiding the data altering the operating point of the filter.

Abstract: A cap operated retractable medical device has an outer body with a hinged connected outer cap which moves between an open and a closed position. The device is used as a blood sampler with a conventional collection tube normally used in such devices. A movable member is entirely enclosed within the outer body. A sliding interference or friction fit holds a retraction body within the mouth of the movable member, and also holds the front end of the movable member within the outer body positioned with the retraction body adjacent a stop. A double ended needle is installed in the retraction body. Cam protrusions on the cap engage the back of the movable member to move it forward as the cap is closed, thereby triggering retraction of the retraction body and its double ended needle entirely within the outer body. Once the cap is closed with the doubl e ended needle safely inside, the device can be safely handled. The device is compact. It c an be as short as the needles it will safely contain.

Granted: 2008-01-29
Abstract: This invention relates to metered usage, and prevention of piracy, of computer software and other intellectual property existing in electronic digital format. The end result of the invention enables soft--ware-on-demand and software subscription services by employing a transformation filter (104) to perpetually regulate, meter, and charge for the usage of software products. The apparatus is implemented as a virtually integral part of the operating system that monitors and "filter" all read, write, and open/execute acccess to and from the I/O devices (106). As the protected material is being accessed, the transformation filter (104) positions itself in the path required for loading the material through the file system and application layers. The material enters the transformation filter (104) in its encrypted state and is decrypted in real-time as it goes through. The material is then handed over to the operating system components (107/108) to fulfill the user access requests.

Abstract: A method of stabilizing a communication system having base stations and mobile stations using integrated control of both signal transmission power levels and signal congestion levels. In particular, the method includes measuring a quality such as a signal to interference ratio of a signal transmitted from a mobile station to a base station and measuring a total received signal power at the base station. The signal transmission power of the mobile station is changed based on comparisons of the measured signals with predetermined threshold values. When the measured total received signal power at the base station exceeds the corresponding predetermined threshold value, a congestion control algorithm is executed to reduce the signal congestion level.

Abstract: An antenna for providing a first antenna pattern at a first frequency of operation and a second antenna pattern at a second frequency of operation from first and second RF signals, respectively. The antenna included a horn which is dimensioned to generate the first antenna pattern from the first RF signal. A  conduit is located within the horn and is configured to propagate the second RF signal in a waveguide mode. A corrugated rod having a first and a second portion is associated with the conduit. The first portion of the rod is located inside the conduit and the second portion of the rod protrudes from the conduit into the horn.  The rod is configured to be responsive to the second RF signal and is operative to transition the second RF signal from a waveguide mode to a surface wave mode and propagate the second RF signal in a surface wave mode along the rod. The rod is configured to generate a second antenna from the second RF signal propagating in a surface wave mode. The first antenna pattern has first antenna pattern characteristics and the second antenna pattern has second antenna pattern characteristics. Changes in the dimensions of the horn will alter the pattern characteristics of the first antenna pattern but will have substantially no effect on the characteristics of the second antenna pattern. Changes in the length of the first portion of the rod will alter the pattern characteristics of the second antenna pattern but have substantially no effect on the pattern characteristics of the first antenna pattern generated by the horn.

Abstract: An actuation device employing square-loop latchable magnetic material having a magnetization direction (polarization) capable of being changed in response to exposure to an external magnetic field is disclosed. The magnetic field is created by a conductor assembly with non-solenoid configuration. Once the magnetization direction of the material is so changed, the external magnetic field is no longer required to maintain the new magnetization direction. The latchable magnetic material is disposed on the mobile electrode of a switching device, and another magnetic material is disposed in spaced relation to the latchable magnetic material on a stationary electrode or surface. By applying an electrical current to a conductor assembly arranged proximate the latchable material, a magnetic field is created about the latchable magnetic material, to change the magnetization direction and thereby enable the attraction or repulsion of another magnetic material located on the stationary electrode. The resulting relative displacement of the mobile and stationary electrodes effects the selective connection or disconnection of electrical contacts carried on or associated with the respective electrodes of the actuation device without requiring additional power in order to maintain the switched state of the electrodes.
