Abstract: An exerciser is provided for application of an anatomically applied force to the jaw for pivoting of the jaw at its tempero-mandibular joint or to provide a motion to the jaw, or resistance to motion of the jaw which is beneficial in facial orthopedics. A structure is provided having curvilinear guide tracks which guide movement of a carriage according to the character of movement that is desired. The carriage is movable to thereby allow corresponding movement of a mandibular jaw member supported by the carriage relative to a maxillary jaw member supported by the exerciser body. Through suitable linkages, motion may be imparted to the carriage or resistance exerted against its motion by manual action, resilient means or a motor. The linkage may provide for adjustment of mechanical advantage or range of motion through selection of slots or holes formed in parts of the linkage structure.

Abstract: ABSTRACT OF THE DISCLOSURE           The reception of the binary digital signal that may also have phase shifts should be accomplished with a supplied clock that has an arbitrary phase relation compared to the digital signal and can deviate somewhat in frequency from the bit repetition rate of the digital signal.   In the disclosed structure, the digital signal is delayed in a delay chain such that a sequence of digital signals having identical phase spacings arises and pulses are derived from the edges thereof.          Query pulses are generated from the leading or trailing edges of a clock, the query pulses being operated with the pulses generated from the digital signals through AND gates.   In a following, further AND gate, each output signal of one of the AND gates is through-connected to an OR gate.  The output of the OR gate is sampled with delayed query pulses in a D flip-flop such that the sampling occurs approximately one-fourth of a clock period following the effective edge of the output signal.

Title: Single-mode, single-polarization optical fiber
Inventor: MESSERLY MICHAEL J
IPC: G02B6/10
Filed: 1990-07-05
Abstract: A single-mode, single-polarization optical fiber ("PZ fiber") can have a large single-polarization wavelength bandwidth when .eta. (as herein defined) for one symmetry axis is positive when calculated from the refractive index profile determined with one of two orthogonal orientations of polarized light and is negative when calculated from the refractive index profile determined with the other orientation, and for each other symmetry axis of the novel optical fiber .eta. is positive for both orientations of plane polarized light. Preferably the absolute values for .eta. when positive and .eta. when negative are about equal for said one symmetry axis. A preferred PZ fiber can be formed by depositing siliceous layers onto the interior surface of a hollow substrate tube of quartz to provide a preform. After forming two parallel flat faces in its outer surface, the preform is pulled to form a PZ fiber having an elliptical stress-applying region.
