In at least one embodiment, the relay is connected to the sound sensor, arranged in the microwave oven, in such a manner that the supply of power by microwaves in the oven, when in use, is interrupted by the relay at a signal from the sound sensor when an acoustic signal is generated by a valve of a container being heated in the microwave oven.

Abstract: A valve system for a container (4, 5), especially for food containers whose contents are intended to be heated, comprises an adhesive layer (3) arranged over an opening portion (6) in the container (4). The adhesive layer (3) is arranged to at least partly release the container (4) adjacent an opening portion (1) in the adhesive layer in case of overpressure and thus form an opening to allow a flow out of the container (4, 5) and, in this flowing-out, emit an acoustic signal by means of said opening portion (1) in the adhesive layer (3) which is made to oscillate by the flow. The valve system comprises at least a second opening portion (2) arranged, in heating of the contents of the container (4, 5), to open before the above-mentioned opening portion (1) in the adhesive layer (3).

Abstract: A method and apparatus for maintaining a plurality of sequence numbers in a plurality of header compressed packets associated with an information context is described. Header compressed packets are transferred on a communication link according to a multi-layer protocol having at least a higher layer and a lower layer. If it is determined that one or more header compressed packets has been dropped, a flag is set on the header compressed packets. A sequence count at the higher layer and lower layer may be reduced by a number corresponding to the number of header compressed packets dropped. The sequence number of each of the header compressed packets is checked at the lower layer against the sequence count and renumbered to match the sequence count. If the sequence number and the sequence count match the flag is cleared. The higher layer is a PPP layer and the lower layer is a Physical Layer.

Abstract: A method and apparatus for reducing delay in the transmission of a plurality of packets by performing IP scheduling and header compression at various layers in a multilayer architecture having a plurality of classifications includes scheduling packets according to classifications. If congestion occurs during scheduling, packets may be discarded. Some packet headers may be compressed thereafter. Packets may further be queued in a first and a second queue, after scheduling, discarding, and compressing, according to at least two classifications. Best Efforts packets may be queued into the lower priority second queue. Classifications may be associated with, for example, QoS levels, delay factors, LFI, and Multilink PPP. Scheduling is performed at higher or lower layers in a multi-layer protocol. The lower layer includes a PPP layer. The lower layer may also include an HDLC layer which creates a tag for packets prior to compression being performed thereupon.

Abstract: Method and apparatus for handling a base transceiver station that has become orphaned as a result of a loss of a base station controller. The method includes determining that contact has been lost between a base transceiver station and a primary base station controller that normally controls the base transceiver station, identifying a secondary base station controller to adopt the base transceiver station, and effecting a handover of the base transceiver station from the primary base station controller to the secondary base station controller. The invention ensures that an operator can maintain some level of service to its customers even if it has lost a base station controller, including the ability to handle emergency calls.

Abstract: A flat four-link rear axle with favorable dynamic properties is presented. The essential aspect lies in that the lower transverse control arm (1), the upper transverse control arm (2) and a compensating control arm (3) are arranged one behind the other (in the direction of travel), so that a spring (15) for supporting the wheel suspension on the body can be supported on the lower transverse control arm (1). The space created by shifting the transverse control arms makes it possible to use a barrel spring with progressive spring characteristic. The associated shock absorber (16) is arranged between the upper transverse control arm (2) and the compensating control arm (3), and its lower fixing eye (26) is mounted in the lower region of the axle carrier (4) so that the upper end of the shock absorber does not extend very far beyond the upper transverse control arm (2) compared with known solutions.

The carrier gas is supplied to the vaporizer at a pressure exceeding atmospheric pressure and is bubbled through the anesthetic liquid in the container in order to become saturated with anesthetic. The flow of gas at the outlet can be regulated as needed. Exact pressure and temperature conditions can be measured and/or regulated with a pressure meter, pressure regulator, thermometer and temperature regulator in order to regulate the partial pressure of anesthetic in the container.

Abstract: An anesthetic system has an external gas reservoir and three gas bellows arranged in the external gas reservoir to alternatingly collect or deliver breathing gas from and to a ventilator unit. In this manner a completely closed system is achieved with minimal consumption of, primarily, anesthetic. The bellows are regulated by a regulatory unit which, via a valve system, can selectively connect a source of drive gas to one or more of the containers in order to compress the gas bellows respectively contained therein. When no drive gas is supplied, each bellows passively expands.
