Abstract: The present invention relates to ophthalmic solutions with antimicrobial activity. The solutions have an antimicrobial compound such as hydrogen peroxide and a boron compound. In one embodiment, the solutions contain a boron compound such as sodium borate that provides antimicrobial activity in addition to that of hydrogen peroxide, particularly during periods following disinfection and neutralization of such solutions. This additional activity reduces the likelihood of microbial growth in contact lens disinfection applications that neutralize hydrogen peroxide.

Abstract: A vibratory sensor with a resonator for measuring angular rotation, such as for example a hemispherical resonator gyroscope (HRG) operating in force rebalance mode, includes circuitry to generate a virtual node and antinode in the resonator standing wave. Shifting a pair of pickoff electrodes from a position directly over an actual node in the HRG standing wave to an offset position where the primary and secondary harmonic contributions at the first pickoff electrode are equal to the primary and secondary harmonic contributions at the second pickoff electrode permits the elimination of secondary harmonics contribution. A virtual node is created by offsetting a pair of pickoff electrodes 22.5 degrees from the actual antinode such that each pickoff electrode includes an equal contribution of the secondary harmonic signal present in the standing wave.

Abstract: A time based digital to analog converter is presented in which known reference voltages are used to create variable period waveforms which, when combined according to a desired computation, can convert digital words into a sinusoidal signal of a precision variable. To illustrate the application of the present invention, a hemispherical resonator gyroscope (HRG) operating in force rebalance is presented wherein a time based digital to analog converter with a variable period output controls the HRG electronics in nulling the standing wave. A rate of the standing wave is calculated, and a software component calculates the fraction of the maximum rate needed to oppose and null the initial rate of the standing wave. The fraction of the maximum rate is converted to digital words corresponding to the number of periods of a clock connected to the circuit.

Abstract: Ophthalmic compositions, such as those used to care for contact lenses, methods of preserving such compositions, and methods for disinfecting contact lenses using such compositions are disclosed. The compositions may comprise an ophthalmically acceptable, liquid aqueous medium and, included therein, an effective preserving or disinfecting amount of grapefruit seed extract.

Abstract: The present invention relates to lenses, for example, contact lenses, and to contact lens cases having antimicrobial properties. More particularly, the invention relates to lenses and contact lens cases made from materials which comprise polymeric materials and effective antimicrobial components.

Abstract: A structural bearing for example for use in supports for pipelines. The bearing comprises a center plate 21 having a PTFE bearing layer insert 22 and above this a co-operating sliding plate 23 with a stainless steel mating plate 24. The center plate 21 is located with respect to a support 25 by a retaining ring 26. Between the center plate 21 and the support 25 there is a deformable feature 27 which deforms when the bearing is subjected to an uneven load, thereby spreading the load more evenly over the support 25.

Abstract: The hose, which is particularly adapted for use with an electrically-driven vacuum cleaning apparatus, comprises a substantially air-tight, flexible tube which is pneumatically coupled between the vacuum pump and the suction head. The suction hose comprises one or more elongated strips which is or are helically wound into tubular form. In a pair of parallelly placed strips, the strip margin of the first strip is secured to an adjacent margin of the second strip at adjoining convolutions of the strips. Electrical conductors are carried by the strips within helically extending cavities formed at the edges or margins of each of the strips and are a portion of that means which electrically couples the cleaning brush to the electrical power supply.
