The amplifier's non-inverting input is connected to the gates of first and second MOSFETs. The drains of the first and second MOSFETs are connected to each other and to the gates of third and fourth MOSFETs. The drain of the third MOSFET is connected to the sources of the second and sixth MOSFETs; and the source of the third MOSFET is connected to the positive supply voltage. The drain of the fourth MOSFET is connected to the sources of the first and fifth MOSFETs. The source of the fourth MOSFET is connected to ground. The inverting input of the sense amplifier is connected to the gates of the fifth and sixth MOSFETs. The drains of the fifth and sixth MOSFETs are connected to each other and provide the output terminus of the amplifier. The first, fourth and fifth MOSFETs are n-channel devices, while the second, third and sixth MOSFETs are p-channel devices.

Abstract: Cryptographic methods and apparatus for forming, checking, blinding, and unblinding of undeniable signatures are disclosed. The validity of such signatures is based on public keys and they are formed by a signed party with access to a corresponding private key, much as with public key digital signatures. A difference is that whereas public key digital signatures can be checked by anyone using the corresponding public key, the validity of undeniable signatures is in general checked by a protocol conducted between a checking party and the signing party. During such a protocol, the signing party may improperly try to deny the validity of a valid signature, but the checking party will be able to detect this with substantially high probability. In case the signing party is not improperly performing the protocol, the checking party is further able to determine with high probability wether or not the signature validly corresponds to the intended message and public key. Blinding can be used while obtaining undeniable signatures, while providing them to other parties, and while checking their validity.

Abstract: A single-housing stepper motor is disclosed comprising a rotor (14) and stator (16) both mounted in a single housing (10) (which may be a part of the base casting) the bearings (40, 42) supporting the rotor for rotation within the housing both being located on the rotor shaft on the same side of the rotor adjacent one another, the opposite end of the single housing being covered with a sealed plastic cover (44). The lamination stack (18) that forms the stator is piloted by machined surfaces (30, 32) into a high tolerence fit within the housing (10), and clamped in place with a simple wave washer/snap ring combination (66, 68). The stator laminations are designed with a decagonally interrupted periphery which can be used without changing the area of the poles (20), and allow space for the wires to the poles to be lead out past the lamination stack. A sealing plastic cover (44) is provided with a special pressure finger (60) to hold the wires (36) running to the stator coils away from the sharp edges of the stack wave spring and snap ring; the cover is also specially designed to capture the wires to relieve the strain on the wires. Alternatively (Fig. 5), the bearings (104, 106) may be located on opposite sides of the rotor (14), the stator (16) is piloted into a precisely aligned position on an inner wall of the housing adjacent the front bearing (104), the other end of the stack being held in place by a bearing holder (116) interposed between the rear bearing (106) and the edge of the stator (16), the holding forces being precisely defined to accurately align the stator with the rotor of the stepper motor. The entire assembly, including the rear bearing, bearing holder and stator support, as well as the stator is held together with a star-shaped spring (15)) comprising a plurality of fingers (106A-D) that slide into and rotate within slots (158A-D) in the housing in a bayonet arrangement. These slots allow insertion of the star-shaped spring under pressure, and rotation under pressure within the groove (160) to a seated position. The same groove then accepts the (160) to a seated position. The same groove then accepts the encapsulating plastic cover (170), preferably inserted through the same openings as the bayonet arms of the spring, though being rotated in the opposite direction.

Abstract: A phase-locked loop is formed by a series circuit of a counter, a register, an arithmetic unit, a low-pass filter, a PI-filter, and a voltage-controlled oscillator. The digital, internal clock signals generated by the oscillator are counted in a counter and are transferred into the register and stored as a current counter reading at points in time determined by time interval clock signals. For example, the time interval clock signals are acquired from reference clock signals by means of a divider and exhibit a lower frequency than the internal clock signals. A drive signal in digital form is determined in the arithmetic unit on the basis of the current counter reading, on the counter reading of the preceding evaluation interval, and on a rated value. This drive signal proceeds via a digital low-pass filter, PI-filter, and D/A converter to the control input of the oscillator, and controls the latter such that the internal clock signals coincide in phase with the reference clock signals.

Abstract: In a method for generating a scalable data stream from one or several blocks of output data of a first encoder and from one or several blocks of output data of a second encoder a determining data block for a current section of an input signal is written. In addition, output data of the second encoder representing a preceding section of the input signal are written in transmission direction from an encoder to a decoder after the determining data block. When the output data of the second encoder are written for a preceding section of the input signal, the output data of the second encoder are written representing the current section of the input signal. In order to signalize where the output data of the second encoder for the preceding section end and where the output data of the second encoder for the current section begin, buffer information is written into the scalable data stream. By the fact that output data of a preceding section follow a determining data block for the current section, a bit savings bank function may be implemented in the scalable encoder and simply be signalized in the bit stream.
