A system and a method for creating a stable and reproducible interface of an optical sensor system for measuring blood glucose levels in biological tissue include a dual wedge prism sensor attached to a disposable optic that comprises a focusing lens and an optical window. The disposable optic adheres to the skin to allow a patient to take multiple readings or scans at the same location. The disposable optic includes a Petzval surface placed flush against the skin to maintain the focal point of the optical beam on the surface of the skin. Additionally, the integrity of the sensor signal is maximized by varying the rotation rates of the dual wedge prisms over time in relation to the depth scan rate of the sensor. Optimally, a medium may be injected between the disposable and the skin to match the respective refractive indices and optimize the signal collection of the sensor.

An optical-waveguide grating modulator is compatible with high-frequency electrical modulation signals of limited bandwidth. The modulator comprises an optical grating formed in an optical waveguide constructed from electro-optic (EO) material and an electrode that is an RF waveguide or RF transmission line that conducts a traveling-wave electromagnetic (EM) field and that contains a portion of the optical-grating waveguide with a continuous grating. The RF input modulation signal is coupled into an RF EM field that propagates through the RF waveguide or transmission line in a direction that is parallel to the direction the light propagates in the optical-grating waveguide and that EM field overlaps the optical-grating waveguide. The light travels along the optical-grating waveguide preferably at the same velocity as the RF EM field travels along the RF waveguide or transmission line.

A cushion, mattress or mattress section for a convertible furniture article defines a plurality of apertures, such as slits or slots or recesses, extending into or through the cushion or mattress section that are cut in a direction at an angle to the first length of the mattress section. The cushion or mattress section expands from its first length to a second length that is longer than the first length upon applying a stretching force to the cushion or mattress section and thereby positioning the mattress section into the open or sleeping configuration. Expansion is due to resilience of the material forming the mattress or mattress section in combination with opening of the apertures. The sleeping surface of the mattress or mattress section may remain substantially planar in both the open (sleeping) position and closed (seating) position.

A back shaft is the double coupling shaft. In order to reduce water loss and soil erosion and increase the buffering power of soil against rain water, the cultivation crossing to mountains is adopted for hilly lands. Therefore, the vehicle body can be inclined to heavier side when cultivating the hilly lands, the weight of the vehicle body is moved to low wheels and the high wheels losing gravity and adhesion to the ground slide and idle, thus causing the phenomenon of deviating from a cultivation ridge path or not walking of a rotary vehicle and bringing great difficulty for implementing mechanization. Consequently, in order to adapt the cultivation in a mountain area, the middle position of the length of the vehicle body is specially and additionally provided with a sliding iron counterweight accounting for 30 percent of the total weight of the vehicle body. When the vehicle cultivates the hilly lands transversely, the sliding iron counterweight can correspondingly move to a higher position under the control of a vertical automatic switch and presses the weight on the high wheels so as to lead the gravities of high and low wheels to be the same or similar.
