Title: Open top infant swing
Inventor: FAIR PAUL
IPC: A63G9/16
Filed: 2001-09-20
Abstract: The present invention is an electrically driven open top infant swing comprising a crossbar that does not extend directly over the top of the infant swing. Thus, as opposed to other prior art swing designs utilizing crossbars, the crossbar of the present invention provides excellent stability and rigidity to the swing described and claimed herein while still allowing relatively easy access to an infant seated in the swing seat. Additionally, the present invention provides an infant swing that is coupled to an electric drive motor by a "moving pivot" thereby allowing the swing to pivot independently of the drive motor and thus avoiding undue strain on the swing motor and gearing.

Title: Method and arrangement in a telecommunications system
Inventor: PETERSEN LARS-GORAN
IPC: H04L29/12
Filed: 2000-03-27
Abstract: A gateway (MG1) interconnects telecom networks (N1, N2) of different types with different signal formats (ATM, IP). A first control unit (CC1), connect ed (C1) to a server, controls connection set up. A second control unit (RC2) provides telecom functions (F21-F28), such as speech coder/decoder or echo extinguisher, to the connection. A third control unit (BC3) establishes connections and sets up switch functions (CP21-CP27) corresponding to the different signal formats (ATM, IP). A signal format converter (CP29) convert s to/from a common signal format (COM1) that the telecom functions uses. A speech request goes via the server to the first control unit (CC1), which requests telecom function (F21) by the second control unit (RC2). This retur ns the address (ADR11) of the telecom function to the first control unit (CC1) which sends the function address (ADR11) and the network address (ADR2) of t he connection to the third control unit (BC3). This interconnects the corresponding switch function (CP23) and the telecom function (F21) after conversion to the common signal format (COM1) in the signal format converter  (CP29). The first control unit (CC1) thereafter requests connection to the next node from the third control unit (BC2), which establishes and indicates  the connection (C41) to the first control unit (CC1). This requests setting up of a corresponding switch function (CP21) by the third control unit (BC3), which connects together the switch function with the telecom function (F21) after reconversion of the signal format. The functions (F21-F28; CP21-CP27) are hardware or software. They can easily be supplemented for new network types or new telecom services.
