In one aspect, the teachings herein provide an enhanced inter-base-station interface and associated processing in which a base station receives a message from a neighboring base station that zero served PLMNs are available in a neighboring cell. In response to receiving that message, the base station removes the neighboring cell from its neighbor list, or otherwise marks the neighboring cell as unavailable, but advantageously does not discard any network performance data accumulated or otherwise generated for that neighboring cell. Correspondingly, should the base station receive a subsequent message indicating that one or more served PLMNs have become available in the neighboring cell, it restores the neighboring cell to its neighbor list and reinstates links or associations, as needed, to the retained network performance data.

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.

The present invention relates to control of GAN-enabled mobile stations operating in a cell of the cellular radio communication network. A signal is transmitted S514 in a cell in a cellular radio communication network, which comprises information that indicates to GAN-enabled mobile stations (MS, MS201) that they may find GAN coverage in the geographical area covered by that cell.

The invention relates to a semiconductor structure for use in the near infrared region, preferably in the range from 1.3 to 1.6 μm, said structure comprising an active zone consisting of a plurality of epitaxially grown alternating layers of Si and Ge, a base layer of a first conductivity type disposed on one side of said active zone, and a cladding layer of the opposite conductivity type to the base layer, the cladding layer being provided on the opposite side of said active zone from said base layer, wherein the alternating Si and Ge layers of said active zone form a superlattice so that holes are located in quantized energy levels associated with a valance band and electrons are localized in a miniband associated with the conduction band and resulting from the superlattice structure. The invention is also directed to a method of manufacturing aforementioned structure.

The invention provides an ultrasonic dental scaler insert having a soft grip, and a method of making it. In the method a soft grip member is provided having an elastomeric wall affixed to a rigid wall. This soft grip member is then connected to an ultrasonic dental scaler insert to form an ultrasonic dental scaler insert having a soft grip.

In a venting arrangement for an internal combustion engine having a cylinder head with an intake duct structure consisting of plastic material and including intake passages, an inlet stub for connection to a vent pipe, and an outlet for communication with the intake passages, the intake duct structure includes a passage with a metal sleeve and a bolt extending through the metal sleeve for mounting the intake duct structure to the cylinder head while firmly engaging the metal sleeve with the cylinder head and a throttle structure which limits the vent flow from the inlet stub to the outlet intake ducts is formed in the passage adjacent the metal sleeve so as to be heated by the metal sleeve.
摘要:
A device for controlling a throttle cross-section of at least one control orifice in a bypass line extending around a throttle valve of an air intake pipe of an internal combustion engine, for regulating an idle speed of the internal combustion engine, and comprising a throttle member, a spring element for biasing the throttle member to an initial position thereof, and a positioning motor for moving the throttle member from its initial position against a bias force of the spring element, upon failure of the spring element and when the positioning motor is actuated, to establish a safety cross-section in the bypass line, a quantity of operating medium flowing through the safety cross-section being less than a quantity of operating medium flowing through a complete cross-section of the control orifice whereby idle operation of the internal combustion engine is insured.
摘要:
An apparatus for resetting computing devices, particularly devices for fuel proportioning or fuel injection, for adjusting ignition timing, and the like, which are controlled by microprocessors, includes a resetting circuit to evaluate the change in the switching state of the ignition lock switch of the motor vehicle when restarted. The evaluation is effected independently of the supply voltage still at the computing device due to a self-sustaining circuit, by means of an integrated differentiation and the differentiation voltage is fed to a comparator at whose output the reset pulse is formed.

The invention is directed to an arrangement for metering fuel to a spark-ignition internal combustion engine equipped with a fuel injection system. The fuel metering arrangement includes a control apparatus which generates injection pulses for controlling the injection valves, the pulses being generated at least in dependence upon the rotational speed of the engine. In the event of a failure of the control apparatus, control of the injection valves is switched over to injection pulses derived from the ignition system of the engine. In this arrangement, the transfer of control may be accomplished either by pulling the central plug of the control apparatus or by automatic error detection via a speed relay.
