Abstract:
A T- or R-type switch network having n inputs and n+p outputs (or vice versa) such that any combination of n outputs may be connected to any combination of the n inputs, n and p being integers selected such that p is greater than 2 and the pair (n, p) is different from the pair (8, 4). The network comprises two end stages each consisting of redundant blocks a selected from three possible types having one input, one input and one output, or one input and two outputs; a series of b intermediate stages arranged between the end stages and each containing a nominal blocks made up of two switches connected to two inputs and two outputs; and (b+1) interconnection blocks for interconnecting the blocks. Herein, a is such that 2a is the smallest integer no lower than p, and b is an integer such that the number c defined by c = n - 2ab is strictly positive and no higher than 2a .

Abstract:
Device for setting the rotor (1) fo a rotary switch in three possible switching positions (positions 1 to 3). Such rotary switches can be for example wave guide or coaxial switches. The excitation of windings in this device for a rotary direction is effected by a pair of conductors (I) with a current pulse. This current pulse, via an initial drive system and by means of a drive torque (5) produced by the latter, moves the rotor (1) from an initial end position (position 1) in the direction of the mid-position (position 3). After the current pulse has been switched off, a permanently imprinted latching torque (4) brings about the further rotation of the rotor (1) to position 3, where the rotor (1) is centred by the shape of the latching torque (4) with a further current pulse on the same pair of conductors (I) a second drive system, which produces a drive moment in accordance with (5b), moves the rotor (1) from the mid-position (position 3) to the end position (position 2).
Abstract:
A micro electromechanical N-way switch comprising normally open micro electromechanical switches and normally closed micro electromechanical switches arranged in up to 2 c rows with C columns of a logical functions matrix. Each row of predetermined serially coupled micro electromechanical switches will create, when selected, a signal path to one way of the N-way switch. The micro electromechanical switches are commonly controlled column by column. Also a phase shift arrangement is shown, with a limited predetermined number of micro electromechanical switches in the signal path, irrespective of the number of selectable phase shift elements.

Abstract:
A channel selection switching to k links without branches and nodes between m inputs and n outputs with four-position waveguide switches with k = min. (m, n), in which several switches are arranged in a ring via their opposite terminals, every second or third switch acts as a bridge switch, the terminal lying transversely to the ring of every third switch is connected to the adjacent bridge switch via a bridge and all unoccupied switch terminals inside the ring are connected to the m inputs and the others to the n outputs or vice versa. The invention is usable with advantage in channel selection on satellites. Assuming that any 4 channels may break down, a secure replacement switching is available and hence reliability is improved. Only 2 additional bridge switches are needed, assuming that through there is one switch for each input. The maximum number of switch connections is 4.
Abstract:
The present invention describes nano-scale fabrication technique used to create a sub- micron wide gap across the center conductor of a coplanar waveguide transmission line configured in a fixed-fixed beam arrangement, resulting in a pair of opposing cantilever beams that comprise an electro-mechanical switch. Accordingly, a nanometer-scale mechanical switch with very high switching speed and low actuation voltage has been developed. This switch is intended primarily for application in the RF/microwave/wireless industry.
Abstract:
A microelectro-mechanical device which includes a fixed electrode formed on a substrate, the fixed electrode including a transparent, high resistance layer, and a moveable electrode formed with an anisotropic stress in a predetermined direction and disposed adjacent the fixed electrode. The device includes first and second electrically conductive regions which are isolated from one another by the fixed electrode. The moveable electrode moves to cover the fixed electrode and to electrically couple to the second conductive region, thus electrically coupling the first and second conductive regions, in response to a potential being applied across the fixed and moveable electrodes. The fixed electrode is transparent to electromagnetic signals or waves and the moveable electrode impedes or allows transmission of electromagnetic signals or waves. In one embodiment of the invention, the fixed and moveable electrodes are configured within an array of similar devices, and each device or groups of devices in the array are individually addressable to actuate the moveable electrodes. In another embodiment of the invention, there is provided a reconfigurable circuit including an array of actuatable devices which are addressed individually or in selected groups, each of the actuatable devices having a fixed electrode formed on a substrate, the fixed electrode including a transparent, high resistance layer, and a moveable electrode formed with an anisotropic stress in a predetermined direction and disposed adjacent the fixed electrode.
