  • Patent number: 6167272
    Abstract: It is known to introduce into a cellular mobile radio network (CN) a test transmitter (TS) which transmits a test signal for reception by mobile stations located in the coverage area of the mobile radio network. A simple, computer-aided method for testing the mobile radio network is disclosed in which the test transmitter (TS) transmits the test signal on a carrier already assigned to a base station (BTS) of the mobile radio network (CN) for transmitting broadcast signals. Thus, each mobile station can receive the test signal in a simple manner. The receive level is transmitted to the base station serving the area in which the mobile station is located, and then passed on to a computer for analysis.

  • Patent number: 6163547
    Abstract: A mobile telecommunication system with Base Transceiver Stations (BTS1-3) coupled to a mobile terminal (MT) via a radio link and exchanging mobile information (AAL-SDU: MUD, MSI) with a telecommunication controller (TC: BSC1-2; MSC). The mobile information contains a telecommunication signaling, such as a hand-over command (HOCOM), e.g. to be transported to the telecommunication controller. According to the ITU recommendation for the ATM Adaptation Layer AAL of the type 2 or 5, the AAL-PDU packets, which may for instance be transported by ATM cells, and wherein the mobile information is mapped, include a User-to-User indication field CPS-UUI or CPCS-UU, respectively, that transparently transports user data. This field is used to transport the telecommunication signaling in the up-link connection to a Base Station Controller (BSC1-2) or to a Mobile Services switching center (MSC), or, in the down-link connection, to base transceiver station (BTS1-3).

  • Patent number: 6097826
    Abstract: A hearing aid to be worn completely in the auditory canal and is adaptable to an individual auditory canal, is individualized by casting of a body in an auditory canal or in a model of an auditory canal. The body is cast in a casting cavity (15) at least partly confined by an extensible membrane (14). In its general condition, before or especially during casting, the inventive hearing aid carries a positioning tip (20) which surrounds the innermost part of the hearing aid radially completely. This positioning tip (20) which is designed to have the form of a tube or of a cap serves for centering the innermost part of the hearing aid when it is introduced into the auditory canal or into the model of such a canal for individualization. After the casting of the body the positioning tip (20) is removed.

  • Patent number: 6093002
    Abstract: A hose has an internal longitudinal channel in its sidewall as a safety device, to provide a prompt indication of impending failure or leakage into or out of the hose. A hose pump featuring such a hose is an improvement over conventional peristaltic pumps. A squeezing member constricts the hose to move a conveyed product along the hose, thereby causing wear on the hose. Such wear usually manifests itself first as a leak through an inner liner of the hose into the channel. The entrance of conveyed product into the channel, which can be detected by a change in pressure or electrical conductivity, is used as an indicator for wearing out of the hose. The use of such a hose minimizes release of hazardous conveyed materials from the hose into the environment or contamination of conveyed sensitive materials such as foodstuffs by the surrounding environment.

  • Patent number: 5933573
    Abstract: An electric motor (12) is supplied with current (i.sub.mot) via a semiconductor switch (14). During operation, the semiconductor switch (14) is driven by a Pulse Width Modulation (PWM) unit 15 using a pulse-formed signal (32). For regulation of the duty ratio of this pulse-formed signal, a first analog signal, which is a function of at least a first motor parameter, is fed to the PWM unit. Further, a second analog signal (STBGR), which is a function of at least a second motor parameter, is fed to the PWM unit for regulation of the duty ratio. As long as the second motor parameter does not exceed a predetermined value, the duty ratio is predominantly controlled by the value of the first analog signal. When the second motor parameter exceeds the predetermined value, the duty ratio is at least predominantly controlled by the value of the second motor parameter, in order to control this second motor parameter through the PWM unit.

  • Patent number: 5917816
    Abstract: During data transmissions between a mobile radio network and a telecommunications network, in order to adapt the data signals to the protocols and modulation rates used by said networks, adaptation processors which perform so-called interworking functions are used which are either implemented in each mobile station of the mobile radio network, or which are implemented in a centralized interworking function that is connected to several mobile switching centers. A centralized interworking function (CIWF) is described for the simple construction of a mobile radio network, which contains different interworking functions (IWF1, . . . , IWFn) for adapting data transmissions between several mobile switching centers (MSC) and different data transmission nodes (MOD, PH, PAD, ISDN) of a telecommunications network (PSTN), and contains a controlled switching network (SWT) which selectively connects the different interworking functions to the mobile switching centers.
