An ultrasonic dental handpiece and insert assembly is provided. Scaler inserts that can be used to clean and polish tooth surfaces are particularly preferred. A sleeve is removably mounted on the handpiece. The handpiece contains a primary coil and the sleeve encloses a secondary coil, which are inductively coupled together so that electromagnetic energy can be transferred between them. A flexible light guide member having a light source such as a light-emitting diode extends from the sleeve. The light guide can bend and flex in any direction allowing the light source to emit light in any direction.

A dental prophylaxis angle and handpiece assembly for cleaning and polishing teeth is provided. The dental prophylaxis angle is removably attached to the dental handpiece by an interlocking mechanism that includes extension locking tabs, a locking annular member, and an interlocking drive member in the handpiece. The prophy angle is securely snap-fitted onto the handpiece and locked in place so that it has minimal lateral movement. After the prophy angle has been used to treat a patient, it can be removed easily from the handpiece and disposed thereof.

It is presented a method for adjusting handover parameters of a processed base station in relation to neighbouring base stations, neighbouring the processed base station. The method being executed in a handover parameter determiner and comprises: obtaining (20) a list of neighbouring base stations of the mobile communication network; determining (22), for each of the neighbouring base stations in the list, a capability to send handover issue report messages; and adjusting (24) the handover parameters based on the determined capabilities for each of the neighbouring base stations in the list.

The invention relates to a method for producing sandwich construction elements for substantially load-bearing and self-supporting building parts. In order to produce a sandwich element which is suitable for self-supporting and substantially load-bearing building parts, since it ensures the necessary transmission of the compressive, tensile and shear forces between the cover layer and core layer and meets the increased fire-protection requirements, the production method proposed contains the following steps: a) producing at least one layer of a mechanically bonded fiber nonwoven which is impregnated with a binder based on at least one heat-curable resin system, and is itself based on naturally occurring raw materials, in particular hemp, flax, jute, sisal, kenaf, cotton and wool and/or mixtures thereof, b) curing the heat-curable resin system in order to produce at least one hardened layer of the fiber nonwoven, wherein, before and/or during the curing operation, a surface structure is applied to at least part of the layer of the fiber nonwoven and/or at least one further binder based on at least one heat-curable resin system is applied to at least part of the surface of the hardened layer of the fiber nonwoven, and fixed thermally, c) bringing a heat-foamable or heat-foamed phenol resin into contact with that surface of at least one hardened layer of the fiber nonwoven which has been modified according to step b), d) possibly annealing, at temperatures ranging from 40 to 80° C., the composite produced in a) to c), and e) curing the further binder based on at least one heat-curable resin system, and possibly applied in b), at a temperature ranging from 150 to 200° C., possibly under elevated pressure.

The invention relates to a method in a Mobility Management Entity (10,11) for handling a setup of an S1 Application Protocol signalling connection between a first radio base station and the Mobility Management Entity (10,11) in a Long Term Evolution radio communications network. The Mobility Management Entity (10,11) receives an S1 Setup Request message from the first radio base station (12). Furthermore, the Mobility Management Entity (10,11) sends an S1 Setup Response message to the first radio base station (12) enabling the first radio base station to handle the setup of the S1 Application Protocol signalling connection. The S1 Setup Response message comprises an indication of at least one supported tracking area code of a tracking area, which tracking area is served by the Mobility Management Entity (10,11).
摘要:
A system and method of scheduling radio resources for a plurality of users in a packet-switched radio communication network. A scheduling number (Si) is calculated for each user before each scheduling event. A weight (Wi) is assigned to each user based on an associated Quality of Service. The Si varies depending on the assigned Wi and when the user entered the scheduling session. Radio resources are assigned to the user having the largest ratio Wi/Si between the weight and the scheduling number.

A motor control centre is provided having an analyst system which is capable of recording data from the monitoring equipment provided therein, and providing a predictive analysis of the data received. The predictive analysis allows the operator to have the ability to schedule routine maintenance to correct a predicted failure of a device to continue operation within a pre-determined set of parameters. Improved operation and maintenance of a controlled system is achieved.
