An error correction circuit and method for reducing a miscorrection probability and a semiconductor memory device including the circuit are provided. The error correction circuit includes an error check and correction (ECC) encoder and an ECC decoder. The ECC encoder generates syndrome data enabling h-bit error correction based on information data and a generator polynomial, where “h” is 2 or an integer greater than 2. The ECC decoder may operate in a single mode for detecting an error position with respect to a maximum of (h−j) bits in the information data based on encoded data including the information and the syndrome data, where “j” is 1 or an integer greater than 1. Alternatively, the ECC decoder may operate in a first operation mode for detecting an error position with respect to a maximum of “h” bits in the information data or in a second operation mode for detecting an error position with respect to a maximum of (h−j) bits in the information data based on encoded data including the information and the syndrome data.

A method and apparatus for simultaneously transmitting, at a common frequency, a plurality of signals on a plurality of beams from a phased array antenna involves forming composite signals that contain the plurality of signals. The composite signals correspond to respective antenna elements in the antenna array and include at least a first signal for transmission via a first transmit beam and a second signal for transmission via a second transmit beam. The phases of the composite signals are a function of signal modulations of the first and second signals and phases of the respective antenna elements required to form the first and second transmit beams. By digitally forming the composite signals, taking into account the modulation phase and beam-forming phase of each signal at each antenna element, hardware requirements are reduced and efficient, saturated amplifier can be employed.

A hydraulic drive assists to increase the acceleration rate of a turbocharger impeller / turbine shaft assembly and provide a secondary means of driving the compressor impeller at lower engine speeds where exhaust gases alone does not generate adequate shaft speeds to create significant induction boost. The hydraulic circuit includes a dual displacement motor, which provides high torque for acceleration yet converts to a single motor for high-speed operation. When the exhaust driven turbine function allows compressor speeds, beyond which the hydraulic system can contribute, a slip clutch allows disengagement of the hydraulic drive. The hydraulic circuit is integrated with the power steering circuit to conserve energy and supportive components such as lines and reservoir. In an alternative embodiment, there is no turbocharger and the hydraulic drive provides means of forced induction air alone.

A linear and curvilinear encoder is provided in which absolute mechanical position and high resolution position determination can be obtained using a cart having a mover with “hybrid” teeth, configured in a curvilinear profile or shape, moving along a curvilinear track with a stator having teeth. The absolute mechanical position and high resolution position determination can be detected on the track by applying an excitation signal to a coil surrounding particular teeth of the stator to produce an electromagnetic (EM) field which can be influenced by the profile or shape of the teeth of the mover. A resulting pick-up signal can then be detected in a pick-up coil surrounding particular teeth of the stator with different harmonics in the pick-up signal corresponding to harmonics of the profile or shape of the teeth.

A method for securing a building to a foundation provides hold-down units that perform double-duty by acting as a compressive load on a floor immediately therebelow due to the force of a seat or base portion thereof. Meanwhile, a flange portion of each hold-down device extends upward to fasten to the upright members in an upper floor applying tension thereto. Thus, an anchoring rod extending through multiple floors of the shear walls may reduce the number of total hold-down devices by an amount approaching half that otherwise required. Likewise, the number of more expensive, automatic, take-up devices used is reduced by approximately half.
