Abstract: A first spring member (74) is provided. One end of the first spring member is fixed to the frame of a IC card reader and other end thereof is urged to the passageway of the IC card. When the IC card is inserted under the other end of the first spring member, the IC card pushes up it against the urging force of the spring and is depressed by the spring to be fixed against the vibration and shock. A second spring member (75) is arranged over the other end of the first spring member, which is come into contact with the other end of the first spring member by a elevating displacement thereof due to the insertion of the IC card. An electric conduction is performed between both spring members and a detection signal indicative of the completion of the insertion of the IC card to the predetermined position is obtained.

Abstract: The invention relates to the particular design of a handbrake lever (1) for the operation of the wheel brakes of motor vehicle trailers. In order to achieve greater tensioning distances without modifying the dimensions of the handbrake lever (1) and without greater expenditure of manual force, the handbrake lever (1) is provided on the one hand with a gas spring (3) passing via a dead point position and with a rocker (7) acting on a Bowden cable (5) of the brake linkage (6). The rocker (7) and the pivot point (8) of the Bowden cable (5) on the handbrake lever (1) are now so arranged that in the basic position they are located on the nearside of a vertical plane (9) passing through the swivel axis (4) of the handbrake lever, roughly in the 1- o'clock position and in the brake limit position on the far side of this plane (9), roughly in the 9-o'clock position. In the final swivel range of the handbrake lever (1) the rocker (7) strikes against the Bowden cable (5) thereby determining the tensioning distance, whilst the gas spring (3) exerts its full supporting force on the handbrake lever (1). <IMAGE>

Abstract: A signal selection and fault detection system that provides triple functional redundancy using the outputs (Y A , Y B ) of two unmonitored primary channels and the output of one or the other of two complementary filters (22, 34) that each receive and process a signal (Y dot IRU) that is derived from a third, independent primary signal source (18) and that is representative of the rate or first derivative of the primary signals (Y A , Y B ). During non-failure conditions, the system output (Y CF1 ) is generated by a normal mode complementary filter 22 from the synthesized rate signal (Y dot IRU) and the selected (10) midvalue one of this output signal (Y CF1 ) and the primary signals (Y A , Y B ). In the event of a suspected failure in one of the primary signals, the output (Y IRU ) of a failure mode complementary filter is substituted (16) for the system output signal (Y CF1 ) as the third input (C) to the midvalue selector (10). The system includes a fault monitor (24) and fault detector (26) to monitor the selected signal and generate switching signals (LOC FAIL, IC FILT, SELCHA, SELCHB) that control the switching between the normal mode and failure mode complementary filters and the isolation of the failed channels. Provisions (30, 32) are made for initializing integrators (52, 54) in the failure mode complementary filter and for varying the band width (C1, C2, A1, A2) of both the failure mode and the normal mode complementary filters as a function of a parameter that influences the primary signals.

Abstract: According to the present invention, a narrow latitude caused by a narrow dynamic range of a solid state image pickup device is improved, and a video camera capable of obtaining a high quality video signal having no signal saturation and black collapse is realized. Scanning is executed in a plurality of times during normal one picture scanning period (one field or one frame period) prescribed in the broadcasting system, and the stop value of a stop mechanism of a camera lens is prescribed so that the levels of video signals corresponding to respective pictures become a fixed value, thus obtaining respective output signals with no satu­ration. These output signals are stored in a memory in each picture unit after A/D conversion. Then, a certain arithmetic processing is performed in synchronization with respective picture positions, and these video signals are outputted in synchro­nization with the vertical synchronizing timing prescribed in the broadcasting system as digital video signals having predetermined levels. These output digital video signals are restored again to the synchronizing frequency pre­scribed in the original broadcasting system thereafter.   The digital video signals thus obtained have S/N improved to be better than the video signal which is outputted from the image pickup device. Accordingly, the dynamic range is also improved sufficiently.

Abstract: It has been proposed to sense the roll rate or roll position of a spin projectile using a pendulum or accelerometer to sense the direction of the Earth's gravity. Gyroscopes may also be used. The prior proposals are sometimes expensive and/or not useful in every situation. Herein there is proposed a roll rate sensor which may form part of a roll position sensor (an "up-­sensor") and which comprises a vibratory element rotated by a motor within a projectile body so its rotation speed about the projectile axis is the sum of the motor speed and the projectile roll rate. The resultant centrifugal force acts on the element so as to vary its effective stiffness and hence its vibration frequency. A transducer is arranged to provide a signal corresponding to the vibration and hence to the centrifugal force and the roll rate. The vibratory element may comprise a metallic or silicon beam element.

Abstract: A circuit for protecting sensitive telephone equipment from voltage or current overloads on the TIP or RING line includes a resistor (R3) serially positioned in the line and a triac (THY1) triggered by a voltage differential across the resistor (R3). A pair of fast diodes (D1,D2) is positioned on the line adjacent to the telephone equipment for momentarily clamping the voltage on the line at that point between ground and the voltage supply of the equipment. The momentary clamping of the voltage creates the voltage differential across the resistor (R3) which triggers the triac. The fast diodes (D1,D2) are capable of passing current for a time sufficient to allow the triac (THY1) to begin shunting current to ground. An enhanced form of the protection circuit includes a second pair of diodes (D6,D7) extending in parallel with the fast pair of diodes (D1,D2) and positioned on the line between the pair of fast diodes (D1,D2) and the triac (THY1). Inclusion of the second pair of diodes (D6,D7) allows the circuit to utilize a triac (THY1) with a slower turn-on time and a higher on-state voltage.
