Abstract: A telecommunication network comprising a roaming mobile station (MS) coupled to its Home IP Network (HIPN) via a mobile network MN, a packet-based wireless communication network (GPRS), preferably operating according to the "General Packet Radio Service" [GPRS], and an INTERNET. The status and the location of the mobile station MS is indicated by location information or signaling, as the "Routing Area Updates" [RAU] to the GPRS network and the "Registration Request" messages (RR) to the Home IP network (HIPN), generated by a location signaling circuit (LS) of the mobile station. In order to optimize the transmission of signaling over the radio link (RL) of the mobile network (MN), i.e. to limit as much as possible the load thereon, only the Routing Area Updates are transmitted over the radio link.      The Registration Request messages are derived from the Routing Area Updates in the GPRS network and so further transmitted to the Home IP      Network (HIPN).

Title: Intonations musicales a echelle bicamerale et enregistrements effectues a partir de telles intonations
Inventor: PYE WILFRED T
IPC: G10C3/12
Filed: 2000-01-19
Abstract: L'invention se rapporte à divers instruments à tonalités en escalier conçus, en ce qui concerne les fréquences générées, conformément à un nouveau système d'accord musical (Fig. 2). Les organes de sélection des tons sont disposés selon un ensemble distinct de spécifications d'intervalles en comparaison des organes de sélection de tons d'un instrument fabriqué de manière conforme à l'état antérieur de la technique pour émettre les fréquences communes du tempérament égal à 12 tons. De manière à générer les tons bicaméraux, le système d'accord préféré utilise deux séries différentes de quintes parfaites pythagoriciennes, séparées par un intervalle de référence connu. Relativement aux douze tons, le nouveau système d'accord est principalement conçu pour améliorer les mauvaises tierces majeures et mineures et parfaire les quintes légèrement diminuées. On utilise sensiblement moins de tons par octave que le nombre requis par l'intonation juste standard. L'invention se rapporte à diverses modifications apportées aux instruments existants, ainsi qu'à un nouveau clavier multitonal enharmonique.

Filed: 2001-12-11
Abstract: A control device for a laundry appliance includes a member which need only be manually shifted through a limited range of travel, from a neutral position to which the control member is biased, in either of first and second opposing directions, to establish a desired cycle and to adjust an operational time for the cycle. The control member is provided with numerous movable contacts which are interposed between fixed contacts.      Shifting of the control member a limited amount in either direction will function to engage a single pair of the contacts, while shifting the control member a further amount in the same direction causes another pair of the contacts to become engaged. In this manner, the contacts are paired to slowly increase or decrease the operational time and to also select either the next or previous operational cycle. User feedback of the selected setting is preferably provided through the use of an illuminated indicator that shifts around a track adjacent operational indicia.

Title: Illuminated tire valve cap
Inventor: FORMOSO VINCENT J
IPC: B60C29/06
Filed: 2001-12-20
Abstract: An illuminated tire valve cap includes one or more loops or sockets for removably receiving a corresponding number of small, chemiluminescent rod(s) therein. The chemiluminescent element(s) is/are separably replaceable from the valve cap, thereby allowing retention of the cap for further use when spent chemiluminescent elements have been removed. The chemiluminescent element retaining loop(s) maybe provided across the top or along the side(s) of the valve cap, at any practicable orientation desired. The present illuminated valve cap "dresses up" the appearance of a vehicle wheel (automobile, truck, motorcycle, bicycle, etc.) without requiring relatively fragile, heavy electrically powered systems, which would unbalance the wheel and tire assembly and which would not provide the desired reliability. The present illuminated valve cap is also valuable in locating the cap at night or in poor lighting, for checking tire pressure and other tire maintenance tasks.
