Title: Adaptive information processing system
IPC: G06N3/08
Filed: 1974-11-07
Abstract: 1457338 Adaptive processing systems NESTOR ASSOCIATES 7 Nov 1974 [6 June 1974] 48232/74 Heading G4R The system has a plurality of input terminals and one or more output terminals connected to the input terminals by a plurality of transfer units. Each transfer unit connects one of the input terminals to the, or one of the, output terminals. A signal s j  on input terminal j appears at the output of the relevant transfer unit as a signal s j A ij . During a learning mode the transfer function A ij  of the transfer unit is modified in accordance with the function of the product of the input signals s and the signals r i  on the output terminals, such that #A ij =f(s 1 , s 2  ... s j - ...s N ; r 1 , r 2  ... r j  ... r n ). It is not necessary with this system to apply desired response signals during learning. The basic arrangement is shown in Fig. 2 : each input signal s feeds a corresponding transfer unit i to provide signals s<SP>1</SP>. Summing unit #produces the sum r of signals s<SP>1</SP> which is fed back during the learning mode to modify the transfer function A of each transfer unit such that #A ij = f(s j  . r;). Instead of being the sum of signals s<SP>1</SP>, output r may be some other function of all s<SP>1</SP>. If there is a plurality of outputs r each input s may be connected to several transfer units (Fig. 3, not shown) to form an adaptive module. Modules may be connected in series, parallel, or series-parallel. The system may be used in a passive learning mode, in which it develops its own responses r 1 -r n  for a given set of input signals s 1 -s n , or in an active learning mode in which it is forced to develop desired response signals for a given set of inputs by applying desired response signals to the output terminals. The output signals may be passed to threshold units so arranged that, for example, the output of each summing unit # is suppressed except for the highest output, this arrangement training the system to provide only one non-zero output signal in response to a given set of input signals. It may be desirable to allow the transfer functions to decay at a predetermined rate during learning so that details of the module's previous learning experience are rendered less significant, i.e. are "forgotten", allowing the module to generalize more rapidly. A specific embodiment of a transfer unit is described (Fig. 14, not shown).

Abstract: 1,235,118. Photo-electric line follower. BRITISH OXYGEN CO. Ltd. Oct.29, 1968 [Oct.31, 1967], No.49445/67. Heading G1A. A line follower head carries two photo-cells the line-of-sight axes of which are parallel and are adjustable between at least two predetermined orientations so that they intersect the plane containing the line or boundary being followed, at least two alternative positions spaced apart in the plane containing both of the axes. The photo-cells may be tilted themselves, or a mirror, prism, etc, may be used to alter the lines of sight of the photocells. In the "normal" position, shown in Fig.1, the two cell axes 16, 18 are vertical, one 6 being co-axial with the axis of the head 2 and the other 8 being slightly forward of it so as to give a certain amount of "lead". In this position, the apparatus is suitable for "ratio" tracing or following, in which the tool controlled travels at a much faster speed than the follower head 2 and therefore demands high accuracy because of the magnification of any tracing inaccuracies. When "direct" tracing is to be carried out, in which tracing and tool speeds are the same, the cell axes are tilted to give a larger amount of "lead" or "anticipation", as in Fig.2, and one of the cells is rendered ineffective, as acceptable accuracy is obtained with only one cell operating. Head construction, Figs.3-5 (not shown). The head comprises a rotatable support tube (20) carrying an inner tube (22) which supports the photo-cells (34) at the end of a Piezo-electric rod (32) by which the cells are oscillated back and forth in a direction (10) perpendicular to the plane containing the two lines of sight axes 6, 8, Fig. 1 (i.e. across the line to be followed). During following or tracing, the head is rotated by a motor (42) and pinion (40) operating on a gear wheel (38) integral with the head support tube (20). Adjustment of the photo-cell orientation to provide the required "lead" for "direct" operation, is by a knob (50) which controls movement of an eccentric cam (46) and ring (48), causing tilting of the inner tube (22) at a ball joint at the top of the head. Fixed stops define the two operational positions. A further feature of the apparatus is a micrometer adjustment for lateral offset of the photo-cells by tilting of inner tube (22) about the ball joint to allow for kerf width. Slip rings are provided for supplying power to the photo-cells and to lamps at the bottom of the lead.
