摘要:
A video intercommunication system comprising at least one local and one remote unit (A,B), wherein each unit is equipped with a picture tube (1) and a TV camera (2) mounted side-by-side. The TV camera is carried on a support (10,12) which allows it to be directed toward the object to be imaged through angular movements thereof imparted by a control (13) operable from the unit exterior. Each unit is further provided with a switch (16), connected in the video signal circuit of the picture tube and operable from outside by means of a pushbutton (18) to temporarily link the TV camera of one unit with its picture tube as well, and then switch it over to just the circuit leading to the picture tube of the remote unit connected thereto. With this system, the object seen by the TV camera can be position set as desired, and the local shooting thereof can be checked as the signal is being transmitted to the remote unit. A particular application of this system relates to communication with deaf people and the transmission of details of a document or a written message.
摘要:
The transducer (10) includes a casing (12) which defines an essentially L-shaped cavity having a substantially horizontal lower arm (16) and a substantially vertical ascending arm (18); a volume of mercury (A) which, in the rest condition, occupies the lower arm (16) and essentially does not occupy the ascending arm (18); an input electrode (30) which penetrates the lower arm (16) from the outside and is permanently immersed in the mercury (A), and a series of separate output electrodes (28₁ ... 28₇) which are spaced along the ascending arm (18) and can be reached in succession by the mercury (A) when it rises in the ascending arm (18) due to an inertial force directed along the lower arm (16) towards the ascending arm (18). The indicator (50) includes an elongate hollow body (52) provided with means (58) for fixing to the bodywork of a motor vehicle and carrying an array of electrical light units (92 1S ...92 6S , 92 1D ...92 6D ) spaced along its length. These units are aligned transverse the vehicle and face rearwardly with respect to the direction of travel. An inertial transducer such as that defined above is mounted in the hollow body (52) and its output electrodes are each connected to at least one of the light units.

摘要:
A programmable thermostat with a display set up to display at least three temperature levels (T1-T5) for each subdivision of a first time period by means of symbols (33) provided on quotas differring from one another and growing with the value of the temperature level setting to display the temperature level settings during the period in the form of a graph consistent with the pattern of the temperature levels during the period.
