摘要： An improved modulator and methods for making the modulator are disclosed. A membrane, preferably circular in shape, is formed over a region of a substrate in such a way that a gap results between the membrane and substrate forming a modulator cavity. The membrane forms a continuous surface over the cavity. In particular, the membrane is not supported by discrete support arms, but rather extends beyond the modulator cavity. Preferably, holes are formed in the membrane to aid in damping its motion and to allow access to underlying layers during modulator formation. According to the method, the modulator is formed by forming a means for creating a gap between the substrate and the membrane, forming a membrane, forming a lateral conduit to aid in removing the means for creating the gap and, finally, by removing the means for creating the gap.

摘要： A modular medical gas services unit with multiple medical gas outlets supported at the same level on the column. The unit preferably comprises a hollow column with an internal space for housing the gas conduits and power lines. The medical gas supply outlets are mounted so that their longitudinal axes extend radially from the vertical axis of the frame, and the longitudinal axes of adjacent outlets intersect to form an acute angle. In this way, the horizontal dimensions of the column can be minimized while the number of medical gas outlets at the desired height is maximized. In one embodiment, the column is pentagonal in cross-section providing five planar support surfaces for five medical gas outlets. In another embodiment, a square column is equipped with angled outlet panels, each supporting two medical gas outlets. Thus, though the frame is four-sided, as many as eight medical gas outlets can be mounted at the same height on the frame.

摘要： This invention is an optical connective device which can have a two-dimensional array of optical fibers. The device can be comprised of a single piece of light conducting material such as glass, plastic or the like shaped to have a slab support member having pillars which project outward from opposing surfaces. The pillars on one of the opposing surfaces are optically aligned with corresponding pillars on the other opposing surface. The length of a pillar can be as small as its diameter. The ends of the pillars can be flat or curved to form a lens and each pillar can be accurately located to an arbitary position. The optical connective device can be sandwiched between chips to provide an integrated circuit chip-to-chip connective device for a stack of two or more chips.

摘要： An article having an optical fiber integrally attached to a micro-device having spaced movable and nonmoving layers suitable for creating optical interference effects is disclosed. In one configuration, the micro-device is suitable for optical modulation, wherein the movable layer is electrostatically actuated to move towards the nonmoving layer. Such movement changes the size of the gap between the layers, resulting in a change in micro-device reflectivity. An optical signal is modulated by controlling micro-device reflectivity via a controlled voltage source. In a second configuration, the micro-device is suitable for measuring pressure. For pressure measurement, the movable membrane moves in response to pressure changes. The change in membrane position again results in a change in micro-device reflectivity. Reflectivity is correlatable to pressure. In a third configuration, the micro-device is suitable for measuring temperature. In the third configuration, the movable membrane is isolated from pressure effects by the addition of an evacuated cavity located beneath the membrane. The region between the movable and nonmoving layers is gas filled. Changes in gas pressure due to changes in gas temperature cause the movable layer to move, affecting micro-device reflectivity. Reflectivity is correlatable to temperature.
