Abstract: A process for the rescue and cloning of a DNA sequence wherein a vector containing said DNA sequence is multiplied in a suitable bacterial host. As the bacterial host, a bacterial strain which is incapable of host restriction is used, such as an  Escherichia coli  C strain. Preferably, a bacteriophage vector which is a suitable cloning vehicle for the bacterial host concerned is used as the vector, the step of in vitro packaging into phage coats being performed by means of a phage packaging extract obtained from a bacterial strain which is incapable of host restriction. The above may be used in a process for detecting mutations in one or more marker genes introduced into a mammalian genome by means of a vector, which process comprises isolating DNA from cells of the transgenic mammal or from the mammalian cells, recovering the vector from said DNA, multiplying the vector in a suitable bacterial host which is deficient with respect to at least one of the marker genes, and testing marker gene expression. Preferably, the DNA isolated from cells of the transgenic mammal or the mammalian cells is pre-purified by fragmenting the DNA by means of a restriction enzyme which does not have a cutting site within the vector, separating the resulting fragments on the basis of a suitable criterion, such as differences in size, and collecting fragments comprising the vector, whereafter the vector is recovered from said pre-­purified DNA.

Abstract: A data processing system having a plurality of processing units (C1, C2), a plurality of memory units (M1, M2) and a communication system providing communication between the processing units and the memory units. The processing units each have a plurality of register sets (R1, R2) allowing them to run a plurality of processes. When a process requires data from memory, which it receives over the communication system, its respective processing unit processes another ot its processes until that requires data. Data is transmitted over the communication system, which may be configured as a grid, in the form of packets. The grid is congigured from routing devices which include first-in-first-out devices for the buffering of packets. The system facilitates the construction of circuits integrated onto a single wafer of semiconducting material. Furthermore the grid structure may also be employed as a local area network and computers having a similar architecture may be connected to the network providing a processing facility of considerable power.

Abstract: An electronic filter for an electroacoustic sys­tem. The system has a microphone for generating an elec­trical output from external sounds and an electrically driven transducer for emitting sound. Some of the sound emitted by the transducer returns to the microphone means to add a feedback contribution to its electrical output. The electronic filter includes a first circuit for elec­tronic processing of the electrical output of the micro­phone to produce a filtered signal. An adaptive filter, interconnected with the first circuit, performs electronic processing of the filtered signal to produce an adaptive output to the first circuit to substantially offset the feedback contribution in the electrical output of the microphone, and the adaptive filter includes means for adapting only in response to polarities of signals supplied to and from the first circuit. Other electronic filters for hearing aids, public address systems and other electro­acoustic systems, as well as such systems and methods of operating them are also disclosed.

Abstract: A signal measurement system with softkey menus for enabling a user to select a desired test setup, including selection of test measurement for the device. The signal measurement system prompts the user with a set of displayed softkey selections via a user interface to step the user through the setup process. Preferably, a signal processing unit (or analyzer) included in the signal measurement system incorporates the user interface in firmware to aid the user in entering a test sequence for the device to be tested. The analyzer preferably displayed the softkey menus on a cathode ray tube included in the analyzer to guide the user. The user is guided through the test sequencing procedure by depressing softkeys. A set of softkey labels (softkey menu) is presented on the display of the analyzer by the firmware for each step in the test sequencing series. As each step of a desired test sequence is entered by the user, the step is displayed on the CRT. Also, the displayed steps are preferably overlaid on data measured in accordance with the test sequence.
