A system using neurological control signals to control a device is disclosed. The system may include a sensor sensing electrical activity of a plurality of neurons over time and a vector generator generating a neural control vector from the sensed electrical activity of the plurality of neurons over time. The system may also include a control filter to which the neural control vector is applied to provide a control variable and an output device controlled by the control variable.

A dynamometer readout (42, 46) and method is disclosed for obtaining dynamometer information (110) related to pumpjacks (10). For this purpose, a change of pivotal direction of the walking beam (18) may be detected by processor (82) utilizing an encoder component (60) with spaced slots (64) therein and light signal devices (68, 70, 72, 74) positioned to have a spacing different from that of the spacing of the slots (64). Software techniques filter out effects of stray mechanical vibrations. An infrared transceiver (46, 50, 100) of a preferred embodiment includes a radio frequency carrier generator (90) and modulator (88) that produces an infrared signal receivable by a low cost consumer radio receiver. The radio frequency modulation technique for infrared signals (96) and related filtering (98, 102, 104) condition formatted infrared signals for utilization in daylight and through a car window for drive-by downloading of data to second computer (108). A sensor (163) may be substituted for the encoder. A sensor (163) may include a moveable light interrupter, such as a ball (160) or a bubble (260), moveably disposed within the sensor. The sensor may also provide one or more apertures (180) for transmitting light through the apertures.

A simple, compact and easy-to-assemble slide rail unit is provided. The slide rail unit reliably restrains right and left rails from sliding even when the right and left rails are installed onto the vehicle floor at an inclination angle different from each other in a longitudinal direction thereof. The slide rail unit includes a slide rail member having an upper rail member and an upper rail member slidably engaged with each other and a lock lever rotatably pivoted to the upper rail member so as to engage with / disengage from an engagement portion formed on the lower rail member. The slide rail unit also includes an operation lever connected to the lock lever within the slide rail member. Between the lock lever and the operation lever, a leaf spring member is disposed for connecting the lock lever and the operation lever therebetween.

When an external force applied condition that an external force that causes a decrease in a rotational speed of an electric motor is applied to the contact member moved by the electric motor is satisfied while the actuation controller is performing a first control for continuously performing a process of providing the electric motor with a command value that depends on an error between an actual rotational speed of the electric motor and a first target rotational speed so as to cause the actual rotational speed to approach the first target rotational speed, then the actuation controller, subsequent to the first control, performs a second control for providing the electric motor with a command value that allows the actual rotational speed of the motor to be equal to, and to fall below, the first target rotational speed at a time of the external force applied condition becoming satisfied.

The invention relates to a lathe tool, comprising a cutter bar, a cutter holder and a blade, wherein a square groove is formed in the cutter bar; a screw and a bolt are arranged in the square groove; the cutter holder is arranged in the square groove and is connected with the screw and the bolt; the screw is movably hinged to the cutter bar of two sides of the square groove; an arc groove is formed in the inner wall of the cutter bar on one side of the square groove; a plurality of limiting threaded holes matched with the bolt are formed in the arc groove; a plurality of positioning holes corresponding to the limiting threaded holes are formed in the cutter bar on the other side of the square groove; the bolt is connected with the cutter bar through the positioning holes and the limiting threaded holes; the blade is fixedly connected to an end angle of the cutter holder. The lathe tool has the characteristics of being simple in structure, capable of adjusting the angle and the like.

Transient response generating circuit A has a first circuit 3 that generates transient response OUT1 in a first polarity direction, a second circuit 4 that generates transient response OUT2 in a second polarity direction opposite to the first polarity, and a transient response synthesizing circuit 6 that combines the transient response OUT1 in the first polarity direction and the transient response OUT2 in the second polarity direction to generate composite transient response OUTC.

In a method and apparatus for acquisition of angiographic data sets of a region of an examination subject, into whose bloodstream a contrast agent has been introduced, a data set of the region to be examined is acquired during a first propagation phase of the contrast agent in the bloodstream as a reference data set to determine reference data, additional data sets of the region to be examined are then acquired, and based on the reference data, variations that are caused in at least some of the additional data sets due to the arrival of a second propagation phase of the contrast agent are determined, and the arrival of the second propagation phase of the contrast agent in the bloodstream is identified based on the determined variations.
