Patent SE-305802-B (SE)
Inventor: BELL P
IPC: G01T1/29
Filed: 1966-04-22
Abstract: 1,123,444. Local copying by scanning. UNITED STATES ATOMIC ENERGY COMMISSION. 18 April, 1966 [3 May, 1965], No. 16834/66. Heading H4F. An original transparent or reflective black- and-white image recording, e.g. a radiographic recording, is scanned photoelectrically to produce a signal which is used to control the production of a further recording by means of a light source 9 exposed to a synchronously scanned colour film system 16, the signal from the photo-electric detector 11 being applied through amplifier 12-14 to control a motor 15 which positions a colour filter wheel 7 whereby each intensity level in the original recording results in a characteristic colour in the further recording. The filter wheel is positioned accurately in accordance with the amplitude of the photo-electric signal by means of a feedback system in which light passing through a variable width slit 20 is detected at 19 to produce a signal which is applied through amplifier 17 as a differential input to amplifier 13. Alternative arrangements based on reflected light or a potentiometer ganged to the filter wheel may be used. Reference is also made to the replacement of the filter wheel by a strip.

Title: Positioning determination using one low-earth orbit satellite.
Inventor: LEVANON NADAV
IPC: H04W84/06
Filed: 1997-09-22
Abstract: A system and method for determining the position of a user terminal (for example, a mobile wireless telephone) in a low-Earth orbit satellite communications system. The system includes a user terminal, at least one satellite with a known position and velocity, and a gateway (that is, a terrestrial base station) for communicating with the user terminal through the satellites. The method includes the steps of determining a range parameter and a range-rate parameter. A range parameter represents a distance between the satellite and the user terminal. A range-rate parameter represents a relative radial velocity between that satellite and the user terminal. The position of the user terminal on the Earth's surface is then determined based on the range parameter, the range-rate parameter, and the known position and velocity of the satellite.

Control and drive mechanisms are provided to block or actuate the inlet door (7) and a feed device (8) and attach to the feed cage (3) compartment elements (4, 5) which can be moved, especially swung, from one longitudinal side to the other, which in one end position free up access to the inlet door (7) and outlet for animals of one animal group and in the other end position free up this access and outlet for animals of the other animal group. Sensors (A1, A2, B1, B2), in particular switches, whereof one (A1, A2) is assigned to one animal group and the other (B1, B2) to the other animal group, detect the end positions of the compartment elements (4, 5). Provided for the inlet door (7) is an intrinsically secure lock (E), which independently of release by the control device allows opening of the inlet door (7) only when the compartment elements (4, 5) are in the secured end positions, which permit access and passage only for the animals of one animal group, therefore condition E = ((A1 AND NOT B1) AND (A2 AND NOT B2)) OR ((B1 AND NOT A1) AND (B2 AND NOT A2))

Granted: 2004-12-15
Abstract: An optical transmission system ensuring high-quality monitor control even if an optical fiber fault occurs. A monitor instruction sending unit sends a monitor instruction. An operating condition recognizing unit receives a response signal and recognizes the operating condition. A filtering unit filters the monitor instruction and the response signal. A monitor control unit monitors the operating condition of its own repeater in response to the monitor instruction, and generates resultant response information. A pump unit generates a pump light to cause Raman amplification within an optical fiber transmission medium. A regeneration control unit performs a regeneration control of the response signal to thereby create a regenerated signal. A modulation control unit modulates the pump light by the response information or the regenerated signal to thereby generate the response signal.
