Abstract: 907,060. Echo sounders. KELVIN & HUGHES Ltd. April 19, 1961 [May 26, 1960], No. 18608/60. Class 40 (7). Echo-sounding apparatus comprises means for transmitting into water pulses of acoustic or ultrasonic waves at two different frequencies along parallel and adjacent paths, means for receiving echoes thereof from fish, and means for indicating the ratio of the amplitudes of the waves received at the two frequencies. Fig.1 shows the variation of relative echo amplitude with length of fish for dorsal aspect at 15 kc/s. and 30 kc/s. In the embodiment illustrated by Figs. 2 and 7 one or both tuned amplifiers 15, 16 has adjustable gain, which is adjusted using a standard target. Variable time delay 17 provides the trigger for time-base generator 18. The cathode-ray tube (C.R.T.) has its X and Y plates arranged to deflect the beam in directions at 45 degrees to the vertical and by the arrangements depicted in Fig. 7 a display, Fig. 4 (c), ensues. In a modification, no time base is provided and the C.R.T. screen periphery is scaled in fish length. In a further embodiment a double-beam C.R.T. is employed, Figs. 8, 9 (neither shown). The time base may be triggered by the sea bottom echo as described in Specification 785,001. Different acoustic absorptions at the two frequencies may be compensated for by gain control of the receiver amplifiers, Fig. 10 (not shown), or control of transmitted energies.

Title: Circuit tester with scanner path assignment
Inventor: WINROTH CALVIN S
IPC: G01R31/28
Filed: 1992-09-11
Abstract: An automatic circuit tester (10) contains in its memory (29) a test program (60 Figure 3) that specifies connections to be made between tester instruments (16, 18) and a device under test (12) in terms of instrument terminals and device-under-test test points without specifying the scanner state that is to implement those connections. A system program (62) inspects the current configuration of the scanner (20) and other tester parts and determines the identities and positions of components of which the scanner is comprised. Then, by consulting a low-level description (66) of each of the scanner components, it searches for paths that will result in the instrument-to-test point connections specified by the test program. The test program (60) can thus dictate a scanner-state change without "knowing" the configuration of the particular scanner employed. <IMAGE>

Title: Groung fault detecting method and apparatus for inverter
Inventor: MIKAMI NOBUHIRO
IPC: H02H3/34
Filed: 1992-09-16
Abstract: In a ground fault detecting method for an inverter 3, zero-phase current is computed 12 on the basis of the detected output current from the inverter. A first value is added to a counter 12a whenever the zero-phase current exceeds the ground level. When the count reaches a predetermined value, it is judged as being a ground fault. Further, when the zero-phase current does not exceed the ground level, a second value smaller than the first value is substracted from the counter 12a. When a ground fault is determined, a control section 7 produces an inverter cut-off signal 15a. The system can respond to intermittent ground faults, but avoids responding to noise. <IMAGE>

Title: Motor vehicle anti-theft device
Inventor: BAMBROUGH ADRIAN
IPC: B60R25/08
Filed: 1993-03-25
Abstract: An anti-theft device for a motor vehicle having a hydraulic braking system and which is actuable to allow hydraulic braking pressure to be applied to the road wheels but preventing the release of that braking pressure so holding the wheel brakes locked, thereby immobilizing the vehicle, comprises an inlet pan 27 for connection to the master cylinder and an outlet port 28. A piston-like valve member 32 is movable by rotation of a key operated cam member 49 to its actuated position in which the seal 39 sealingly engages end wall 30 to isolate the inlet part 27 and axial passage 41 from the outlet part 28. A further small axial movement of the valve member 32 to further compress the seal 39 will cause the hydraulic liquid downstream of the anti-theft device to apply a braking force to the road wheels. Since a return fluid path from the outlet port 28 to the inlet part 27 is blocked by the seal 39, the hydraulic pressure locking the road wheels cannot be released and hence the vehicle becomes immobilized. Non-return valve 42, radial passage 40 and blind bore 37 may be omitted. <IMAGE>

Title: Electro-optic reconnaissance
Inventor: WIGHT RALPH H
IPC: H04N3/30
Filed: 1993-12-09
Abstract: To perform long range, sector scan panoramic electro-optical reconnaissance of a scene, e.g. from an aircraft (102), at increased aircraft velocities, the scene is scanned at a non-linear scan velocity. The effects of the non-linear scan velocity are electronically removed to correct the aspect ratio of the final image. As described, a focal plane array (412) detects an image of the scene, and the image is converted into an electronic signal which is a digital representation of the image. A lens arrangement is used to focus a narrow slit of the scene onto the focal plane army, and a rotating prism scans the slit across the scene at a non-linear scanning velocity. The electronic signal is transmitted to a ground station (402) where it is processed to provide visual image data that represents the scene. Distortion induced into this data as a result of the non-linear scan velocity is removed (434) to provide a distortion free final image. <IMAGE>
