Title: Constant range ultrasonic motion detector
IPC: G08B13/16
Filed: 1983-08-02
Abstract: A constant range ultrasonic motion detector (10) has an ambient atmospheric condition sensor (38) which senses the temperature, pressure, and percent relative humidity of the ambient atmosphere and produces therefrom a range compensation signal to adjust the sensitivity of the ultrasonic motion (10) for stabilizing the range. The range compensation signal is applied to adapt detector amplifier gain and/or threshold level to the variation between design and ambient conditions. In one embodiment, an analog summing network at the ambient atmospheric sensor (38) outputs provides the range compensation signal and in a second embodiment a microprocessor is operative to provide the range compensation signal.

Patent PT-80587-B (PT)
IPC: H04J3/06
Filed: 1985-06-04
Abstract: In a broadcasting system with time division multiplexing of digital signals containing a synchronization pattern and analog signals, sync extraction is achieved with a process including detecting the extreme values of the signals to be subjected to decoding, after they have been amplified with a gain G, with a time constant compatible with the low cut off frequencies to be accomodated; the gain G is controlled as a decreasing function of the difference between the extreme values with a time constant greater by several orders of size than the repetition period of the multiplex; before decoding and determination of the extreme values, there is added to the amplified signal a DC component which is a decreasing function of the sum of the extreme values, until the retrieval of the clock signal and identification of the synchronization pattern downstream of the coding.

Inventor: RUMREICH MARCK FRANCIS
IPC: H04N5/52
Filed: 1988-05-04
Abstract: In an automatic gain control (AGC) network in a video signal processing system, a comparator (70) responds to an input control signal for providing an output control signal to an RF tuner (23) amplifier for decreasing its gain below a normal maximum level when the input signal exceeds a threshold value. The operation of the comparator is inhibited beyond a predetermined level of the input control signal, to prevent a false output gain control signal from being developed. The input control signal is applied to the comparator (70) through transistor (84). As the input control signal falls beyond the predetermined level, the comparator (70) input is prevented from falling by inhibiting clamp transistor (90).

Abstract: 1,116,530. Electric selective signalling. SECURITON A.G. 27 Sept., 1965 [28 Sept., 1964], No. 40922/65. Heading G4H. An alarm system in which a plurality of outstations signal to a central station, e.g. by wireless, includes means whereby the central station can check the operation of each out-station. When the alarm at an out-station is tripped, a coded disc rotates, giving pulses which pass via the wireless link to the receiver at the central station and are recorded on tape by a stylus. When checking, an operator at the central station sends a preset enquiry signal to which the required out station responds by returning the signal derived from the coded disc. This signal passes through a different part of the transmitter. At the receiver it is recorded on another tape. Inspection of this tape indicates whether or not that out-station is in order.

Title: Method and device for measuring and orienting logs to be sawn
Inventor: OLSSON L J
IPC: B27B27/00
Filed: 1978-11-29
Abstract: A method and arrangement for measuring, and the machinery for handling logs involves a saw machine with a mainly vertical saw plane, a feeder unit which feeds the logs through the saw machine, via a mainly longitudinal, horizontal movement parallel to the saw plane, a feeder station which is located separately to the feeder unit, and a transporter upon which logs are transported from the feeder station to the feeder unit. The log adopts a favourable position in the feeder station in a rotational mode, which is retained during transport of the log, and on its transfer to the feeder unit which has laterally adjustable grip-arms holding the log during feeding. Before the transfer takes place, the relative position is decided between a calculated plane, which extends through the log, as well as the reference plane used for the feeder, whose position is assessed relative to the saw plane, and the grip arms are then adjusted according to the relative position so that the log, when it is fed in by the feeder unit, adopts the above mentioned calculated plane in the desired lateral position to the saw plane.<IMAGE>

Inventor: ARNBERG PETER
IPC: G01B11/245
Filed: 1984-05-30
Abstract: A mobile system for measuring characteristics of traffic-bearing surfaces has laser cameras mounted on a vehicle for measuring the distance to the surface as the vehicle travels along it. A rotating laser at a known, fixed elevation generates a laser plane over the surface while a second oscillating or rotating laser generates a substantially vertical laser plane in the direction of measurement of the surface. The vehicle carries a pair of sensors for detecting the incidence of the laser planes thereon. The sensors generate signals which represent the exact vertical and lateral position of the vehicle with reference to the fixed laser planes at any point on the surface. These signals are used to obtain values representative of the vertical elevation of the surface compensated for deviations in the vertical position of the vehicle during the measurement, and to record and control the measuring path of the vehicle.

Abstract: A steel tube (1) is used with an external dia. of 12 mm. Around the tube is wound clockwise a primary bi-metal spring (2), which is fixed to the tube at one end (3) by a screw (4) by a screw (4). At its other end (5), the spring is attached to a second tube (6) rotatably fitted on the steel tube. The second tube is fixed to a secondary bi-metal spring (7) which at its end (8) opposite the second tube is fixed to the steel tube by a screw (9). The springs (2,7) e.g. have the dimensions of 1 x 6 mm in cross-section. On heating, both springs attempt. to turn counterwise to the sun axially from each of their fixture screws (4,9). An even temp. increase permits that the second tube cannot, rotate on the steel tube. If, on the other hand, the one spring is heated more than the other, the second tube turns counterwise to the sun axially from the screw.
