Abstract: A semiconductor laser (2) constitutes a monolithic source whose intensity is modulated at a frequency lying in the microwave frequency range, typically 10-20 GHz to 100 GHz. It is based on coupling between the longitudinal modes of the laser, with intensity modulation being given by beats between the various modes of the laser. Optimization and control of the laser are made possible by splitting the optical cavity (6, 8, 10) of the laser into successive sections (20, 22, 24). The invention is particularly suitable for telecommunications applications.

Abstract: A remote control apparatus comprises a transmitter to transmit coded signals, and a receiver to receive and decode the signals. The receiver is associated with a plurality of control elements each adapted to be acti­vated in response to the decoding of a predetermined respective signal, and each adapted to remain activated while the receiver continues to receive a signal from the transmitter. Each control element is associated with timing means so that whenever a control element is activated the control element remains activated for at least a period of time as determined by the timing arrangement. This may prevent inadvertent "drop-out" due to voltage drop caused by a power surge. Also each control element is adapted to inhibit operation of the other control element while the first element is actu­ated and for a brief period of time after the first con­trol element has ceased being actuated.

Abstract: An antigen which produces immunity against homologous or heterologous challenge with babesia of cattle. The antigen is immunoreactive with a monoclonal antibody or polyclonal antisera recognising a protein located on the surface of babesia-infected erythrocytes and within a spherical or mitochondrion like organelle. The antigen can be prepared by (i) preparing nucleic acids from babesia infected erythrocytes depleted of leucocytes; (ii) forming a cDNA or genomic library from nucleic acids obtained in step (i); (iii) screening said library formed in step (ii) with a suitable probe to identify clones of interest; and thus providing DNA inserts for an expression vector which may be used to transform an appropriate host; (iv) obtaining a recombinant polypeptide from said transformed hosts which is protective against babesiosis. A monoclonal antibody reactive with the antigen, a DNA sequence which produces a protein protective against babesiosis when administered as a vaccine, and a vaccine including the antigen in combination with an adjuvant is also included in the inventive concept.
