Title: Management of packet switched connections in a communication network
Inventor: AHMAVAARA KALLE
IPC: H04L69/14
Filed: 1999-06-24
Abstract: In connection-oriented switching of packet data in known mobile communications systems, resources of the transmission path between the serving node (SGSN) and the radio network subsystem (RNS) and memory resources of the radio network subsystem are reserved unnecessarily due to the burst-like nature of packet data. Thus the transmission network's limited address space and the radio network subsystem's management resources are consumed. The invention concerns such connection management in a mobile communications system, which is suitable for packet-switched data transmission. The method according to the invention is characterized in that the logical connection between the serving node (SGSN) and the radio network subsystem (RNS) is released, so that the logical connection between the serving node (SGSN) and the mobile station (MS) remains, and the released logical connection is reconnected, when relaying of user data starts.

Title: Apparatus and method for allowing object-oriented programs created with different framework versions to communicate
Inventor: JABLONSKI MARC
IPC: G06F9/44
Filed: 1998-12-08
Abstract: A set of stream writer and reader class and methods enable object frameworks to communicate with each other despite problems with missing classes due to mismatched versions. The stream writers are modified to deal with a new version of a class that extends from a class in an existing version by writing alternate object information compatible with the existing version when the future object class information is streamed. In this manner, alternate object information is written for each older version. The information for each of the alternate objects corresponding to each oder version is added after the existing object information as an extension with the length of the extension written at the beginning. The stream readers are modified so that when an older version stream reader reads the object information and does not understand the first alternate object (which might correspond to a later version), it skips the length specified for that extension and reads the second alternate object. If the second alternate object information is not understood, the reader skips the non-understood object information and continues with each alternate object. If none of the alternates is understood, then an exception is thrown. In one embodiment, the information for alternate objects which are not used is not discarded, but is instead saved in a temporary storage. Then, if the object is streamed out again, the stored information is added back into the stream.

Title: Programmable dynamic range receiver
Inventor: CICCARELLI STEVEN C
IPC: H03M1/18
Filed: 1998-12-08
Abstract: A programmable dynamic range receiver which provides the requisite level of performance at reduced power consumption. The .SIGMA..DELTA.  ADC within the receiver is designed with one or more loops. Each loop provides a predetermined dynamic range performance. The loops can be enabled or disabled based on the required dynamic range and a set of dynamic range thresholds. The .SIGMA..DELTA. ADC is also designed with adjustable bias current. The dynamic range of the .SIGMA..DELTA. ADC  varies approximately proportional to the bias current. By adjusting the bias current, the required dynamic range can be provided by the .SIGMA..DELTA.  ADC with minimal power consumption. A reference voltage of the .SIGMA..DELTA. ADC can be decreased when high dynamic range is not required, thereby allowing for less bias current in the .SIGMA..DELTA. ADC and supporting circuitry. The dynamic range of the .SIGMA..DELTA. ADC is a also function of the oversampling ratio which is proportional to the sampling frequency.  High dynamic range requires a high oversampling ratio. When high dynamic range is not required, the sampling frequency can be lowered.

Inventor: KURELEK JOHN
IPC: E02F9/22
Filed: 2000-09-06
Abstract: The two boom members and hydraulic cylinders of a knuckle boom tree harvesting machine are so arranged and proportioned that with a single control movement during reaching and retracting actions the working tool head is made to travel in an approximately horizontal path. The cylinders and control valve are so connected that during horizontal reaching action load-supporting pressurized oil from a collapsing cylinder is not required to be dumped to the reservoir in the conventional heat generating manner, but is rather shunted directly to an extending cylinder where it continues to do useful load support work. Energy waste to hydraulic oil heat and fuel consumption is significantly reduced. Although these advances have been particularly developed for disc saw felling and stroke delimbing of trees they can also be applied to other knuckle boom applications where horizontal reaching is a major function.
