Abstract: A method of measuring acceleration using an optical sensor. In the optical sensor, acceleration, acoustic velocity, or displacement (vibration) causes a corresponding shift in the center wavelength of the sensor output. The sensor can be coupled to a high-speed interferometric interrogator through an unbalanced fiber interferometer. The unbalanced interferometer functions to translate optical wavelength shift into phase shift, which is easily demodulated by the interrogator.

Abstract: Said invention is a unique modi or set of immunological techniques/methods, by which to develop various types of infertility vaccines, primarily designed to reduce fertility or to produce infertility in animals and/or in humans. Said reduced fertility or infertility may be permanent or exists with variable duration. The immunological infertility responses, resulting from said uniquely developed vaccines (as affected/created by the proposed methodologies), may be superior to currently existing infertility vaccines {referenced, herein}, since they (the vaccines resulting from the proposed methods, herein) would contain a far greater diversity/variety of antigens; and are therefore, considered as polyantigenic vaccines, herein. A larger diversity/variety of antigens may better elicit a greater diversity/variety of endogenous antibodies. A greater variety of antibody types and antibody variable sites may enhance the infertility response.

Abstract: This document discusses, among other things, a connector for an optical imaging probe that includes one or more optical fibers communicating light along the catheter. The device may use multiple sections for simpler manufacturing and ease of assembly during a medical procedure. Light energy to and from a distal minimally-invasive portion of the probe is coupled by the connector to external diagnostic or analytical instrumentation through an external instrumentation lead. Certain examples provide a self-aligning two-section optical catheter with beveled ends, which is formed by separating an optical cable assembly. Techniques for improving light coupling include using a lens between instrumentation lead and probe portions. Techniques for improving the mechanical alignment of a multi-optical fiber catheter include using a stop or a guide.

Abstract: A logic signal controlled switching video amplifier is disclosed having minimal power dissipation. By utilizing diode and transistor amplifier switching techniques, charging and discharging currents in the video amplifier are controlled. The stray capacitance associated with circuit wiring and cathode ray tube interelectrode capacitance can be rapidly switched without requiring low impedances or high DC current levels in the video amplifier.

Abstract: A system for developing horizontal and vertical deflection signals for drawing a vector of predetermined length and angle on the face of a cathode ray tube is disclosed. Variable rate integrators are caused to integrate at rates respectively definitive of the sine and cosine functions of the vector angle for a period of time which is proportional to the length of the vector to develop Y and X deflection signal outputs which collectively define the vector.

Abstract: A controller for a vector generator used in drawing vector defined symbology on the face of a cathode ray tube is disclosed. Digital storage definitive of contiguous vectors which comprise each symbol to be drawn is addressed by a character address output from a microprocessor which also outputs rotation angle data. Rotation of each segment comprising a symbol is accomplished by simple addition of predetermined most-significant bits of the rotation angle data and segment angle data addressed from storage by the microprocessor, with the summation applied as addressing input to a ROM look-up table from which sine and cosine functions of the resultant angle are obtained. The sine and cosine functions are applied as inputs to respective integrators to establish their respective rates of integration over a period of time proportional to vector length.

Abstract: A flag receiver circuitry for either a low level or a high level flag input is described. By utilizing the common mode rejection capability that must be incorporated in a differential flag receiver circuit, the same circuit can be connected as a single ended input receiver for a high level flag by effecting a clamp of the inverting input terminal voltage of the differentially configured operational amplifier employed to provide a high level flag trippoint output.
