Abstract: The invention proceeds from the finding that the deflection of a mirror-coated membrane surface can be used for the purpose of deflecting a light beam, of predetermined intensity, passed via appropriate optical means, in accordance with the measured pressure, so that the intensity of the light to be reemitted is variable as a function of the measured pressure. A measurement body is provided, in which an at least partially mirror-coated membrane is tensioned in such a manner that it is positioned with its mirror-coated surface in its rest position surface-parallel at a spacing which is slightly greater than an expected maximum deflection of the membrane, to an end surface of a graduated lens, and in which the graduated lens is positioned so that this end surface is disposed eccentrically opposite the membrane, so that as a result of flexings of the membrane which are caused by pressure effects the beam path of a light passed via the other end surface by means of optical waveguides as entrance fibre is displaceable within the graduated lens in consequence of the altered angle of incidence at the mirror-coated surface, so that the light intensity in an exit fibre is variable. <IMAGE>

Abstract: A reflective afocal beam expander optical system 50 is disclosed for transmitting electromagnetic (EM) energy. The beam expander, in the preferred embodiment, is comprised of a reflective afocal system 30 including a section of a primary parabolic mirror 32, a section of a secondary parabolic mirror 34, and a beam splitter 48. The two mirrors have a common axis of rotational symmetry 40 and a common focus point and the centerline 46 of the incoming EM energy is displaced from the axis of rotational symmetry. The beam splitter 48 is positioned with respect to the primary mirror 32 to receive the edge rays of the EM energy and cause the EM energy to be folded and exit through a window while clearing all optical elements. A viewing system 70 having a viewing axis 72, through the beam splitter48 allows a viewer to see through the same window 67 as the exiting EM energy. A second refractive afocal optical system 52 is made integral to the specific laser system being used in order to control beam expansion ratios.

Abstract: While a first access request signal is sent to a memory for a first data of a first data element number of leading through trailing elements, a register (12) holds a trailing address which is assigned to a memory unit for the trailing element. Responsive to a second access request signal for a second data, a difference calculator (13, 14) calculates a difference between the trailing address and a leading address which is assigned to a memory unit for the leading element of the second data. While the first access request signal is sent to the memory, another register (15) holds a reference number that is equal to a memory unit cycle time during which each memory unit is rendered busy by each access request signal. After disappearance of the access request signal, the reference number is reduced one per clock cycle. A comparator (17, 18) compares the difference with the reference number to produce an access enabling signal which enables delivery of the second access request signal to the memory when the reference number becomes not greater than the difference in consideration of the number of memory units accessed in each clock cycle.

Abstract: Voltage responsive circuits particularly for detecting MOS integrated circuit input voltages greater than V cc . Various circuits are proposed each of which employ an MOS transistor (Tr1) connected in series with a capacitor (C1) and arranged between the V cc  rail and an output terminal (T1). The input voltage (V in ) is applied to the gate of the MOS transistor (Tr1). The signal and/or impedance available at the output terminal (T1) varies in dependence on whether the input voltage is high or lower than V cc . An a.c. signal input may be applied to lower plate of the capacitor (C1) via a resistor (R1 - Fig. 3) and an a.c. signal detector determines the magnitude of the signal at the output, large corresponding to V in  < V cc  + V T  and small corresponding to V in  > V cc  + V T , (V T  is the threshold voltage of Tr1). Alternatively a charging current impedance detector (Figs. 4 and 5) or a clocked circuit (Figs. 6 and 7) may be employed.

Abstract: A pallet is provided for positioning workpiece components (e.g. a vamp V and quarter portions RQ, LQ of a shoe upper) in position for stitching the portions together, where, when the various components are in a flat condition, the regions (corresponding to the desired stitching paths) of the various components are not in overlapping relationship; that is to say, the pallet enables distortion of at least one of the components in order to bring the regions of the various components into such overlapping relationship. This is achieved by locating e.g. the quarter portions RQ, LQ in a flat condition in relation to a slot (14) of the pallet, which slot corresponds with the desired stitching path, and thereafter positioning the other component, e.g. the vamp V, with part of said region thereof in overlapping relationship with corresponding parts of the quarter portions, and clamping the vamp so that the parts of the regions thereof and of the quarter portions are maintained in overlapping relationship. Thereafter, the remainder of the regions of the vamp can be positioned by distorting the vamp manually, whereafter the vamp is clamped in distorted condition, maintaining the remainder of the regions in such overlapping relationship.
