摘要： One embodiment relates to a laser positioning device for sensing relative movement between a data input device and a surface by determining displacement of image features in a succession of images of the surface. The device forms a single integrated package, which includes a planar substrate and a transparent encapsulant that also embodies a collimating lens. Both a coherent light source and a sensor array and associated circuitry are configured on the planar substrate. Another embodiment relates to a method of sensing relative movement between a data input device and a surface. Coherent light is emitted from a laser and collimated so as to form a collimated illumination beam with a predetermined diameter, D, and a substantially uniform phase front. A speckle pattern is generated by impingement of the collimated illumination beam on the surface and detected by a sensor array. Other embodiments are also disclosed.

摘要： The present invention provides compositions and methods for administering oxybutynin while minimizing the incidence and or severity of adverse drug experiences associated with oxybutynin therapy. In one aspect, these compositions and methods provide a lower plasma concentration of oxybutynin metabolites, such as N-desethyloxybutynin, which is presumed to be contributing at least in part to some of the adverse drug experiences, while maintaining sufficient oxybutynin plasma concentration to benefit a subject with oxybutynin therapy. The invention also provides isomers of oxybutynin and its metabolites that meet these characteristics of minimized incidence and/or severity of adverse drug experiences, and maintenance of beneficial and effective therapy for overactive bladder.

摘要： A Lyot depolarizer for depolarizing a laser with multiple longitudinal modes comprises two segments of PM fiber optimized for length as a function of the longitudinal mode spacing of the laser source, and not as taught in the prior art as a function of the laser coherence length. The present invention has found secondary coherence peaks in the coherence function of a multiple longitudinal mode source, which can significantly worsen the DoP if the PM fiber lengths are significantly extended beyond optimum, contrary to the teaching in the prior art. The present invention makes use of the periodic structure of the source spectrum by converting half the longitudinal modes to an orthogonal polarization state. As a result a significantly shorter fiber depolarizer is needed than for a single longitudinal mode source. Greater temperature stability is achieved by properly adjusting the lengths of both segments of PM fiber.
摘要翻译：用于对具有多个纵向模式去激光的Lyot去极化器包括针对作为激光源的纵向模式间隔的函数的长度优化的两段PM光纤，并且不像现有技术中作为激光相干长度的函数所教导。本发明已经发现多纵向模式源的相干函数中的二次相干峰值，与现有技术中的教导相反，如果PM光纤长度显着延伸超出最佳值，则可以显着恶化DoP。本发明通过将纵向模式的一半转换为正交偏振状态来利用源光谱的周期性结构。因此，对于单个纵向模式源，需要明显更短的纤维去极化器。通过适当调整PM纤维两段的长度可实现更高的温度稳定性。

摘要： An upconversion fiber laser uses a pump source which may be another fiber laser, such as a high power, diode-laser-pumped, fiber laser. The upconversion fiber laser includes an optical fiber whose core region is doped with an active lasing ionic species capable when optically pumped of undergoing upconversion excitation, such as certain rare earth ionic species, and which is embedded in a cladding of the optical fiber. Use of a fiber pump laser can improve coupling of pump light into the optical fiber, thereby achieving higher pump intensities in the core region and improved upconversion efficiency. The upconversion fiber laser's resonant laser cavity is defined by feedback means which can include at least one reflective grating formed in the optical fiber, as well as a reflective end face of the optical fiber. Any portion of the optical fiber that lies outside of the resonant laser cavity, such as any portion beyond the integral reflective grating, may act as an optical power amplifier for the upconverted laser output. The disclosure includes other embodiments in which pump brightness can be further increased with multiple pump sources.

摘要： A bobbling toy exciter is provided for gently tapping the bobbling portion of the bobbling toy to create a continuous movement of the bobbling portion. A motor drives a flexible arm in periodic movement which causes the arm to strike the bobbling portion, for example the bobbling head of the toy. A bob or other mass may be added to the end of the flexible arm to more effectively strike the toy. The flexible arm may extend transversely from the shaft of a rotating motor. The flexible arm may also transversely extend from a pivoting vertical rod. The present bobbling toy exciter gently creates movement and action in bobbling toys which would require manual excitation, so that the user may continuously enjoy the bobbling movement.
