  • Patent number: 6612690
    Abstract: An ink containment and dispensing device for an ink-jet printer is provided with a main reservoir in the form of a flexible pouch, which is typically maintained at ambient pressure. The main reservoir is coupled to a variable volume chamber via a one-way valve which allows the flow of ink from the reservoir to the chamber and prevents the flow of ink from the chamber to the reservoir. The chamber is coupled to a fluid outlet, which is normally closed to prevent the flow of outward ink. However, when the ink supply is installed in a printer, the fluid outlet establishes a fluid connection between the chamber and the printer. The chamber is part of a pump provided with the ink supply that can be actuated to supply ink from the reservoir to the printer. The pump has a linearly acting pumping member and a flexible diaphragm that overlies the pumping member, the diaphragm being impervious to the transmission of oxygen and moisture therethrough to prevent degradation of the ink within the chamber.

  • Patent number: 6612705
    Abstract: This invention deals with the broad general concept for focussing light. A mini-optics tracking and focussing system is presented for solar power conversion that ranges from an individual's portable system to solar conversion of electrical power that can be used in large scale power plants for environmentally clean energy. It can be rolled up, transported, and attached to existing man-made, or natural structures. It allows the solar energy conversion system to be low in capital cost and inexpensive to install as it can be attached to existing structures since it does not require the construction of a superstructure of its own. This novel system is uniquely distinct and different from other solar tracking and focussing processes allowing it to be more economical and practical. Furthermore, in its capacity as a power producer, it can be utilized with far greater safety, simplicity, economy, and efficiency in the conversion of solar energy.

  • Patent number: 6612706
    Abstract: A micromachined apparatus for reflecting light is described that is designed to reduce losses in quality or intensity of light. Mirrors are used having lengths that are longer than their widths to reduce clipping of light when a mirror is located at an angle with respect to light falling thereon. Relatively long mirror torsion components are used to reduce forces required to pivot the mirrors. Regardless of the dimensions of the mirrors and the use of long torsion components, the mirrors are still located relatively close to one another. The relatively close positioning of the mirrors is due to a combined use of notches formed in support frames to which the torsion components are secured, oval shapes of the mirrors which take up less space than rectangular shapes, matching oval openings in the support frames, and the arrangement of the support frames in a non-rectangular array wherein tips of the support frames are located between one another.

An LED (32) is mounted to a circuit board (34) so that its axis is angularly offset from the axis of the circuit board. When the light assembly is assembled, a side edge of the circuit board is seated in one of the tray slots. If a first one circuit board side edges is seated in a first slot, the LED has a first angular orientation relative to the longitudinal axis of the housing. Alternatively, the second circuit board side edges is seated in the second slot so that the LED has a second angular orientation relative to the longitudinal axis of the housing. This allows selective control the angular orientation of the emitted light beam relative to the longitudinal axis of the housing.

  • Patent number: 6612730
    Abstract: A light scattering pattern is disposed near the focus of a curved surface regarded as a concave mirror. Scattered light reflected by the curved surface and emitted from a planar surface is focused at a predetermined focused position. If the predetermined focused position and an image surface to be read are aligned with each other, then the scattered light from the light scattering pattern falls fully on the image surface without being wasted, so that a spatial light intensity distribution in an auxiliary scanning direction is uniformized.

  • Patent number: 6612736
    Abstract: An estimated brake rotor temperature is provided including a cooling effect during active braking as well as when braking is inactive. The cooling effect is based on a difference between the rotor temperature and sensed ambient temperature and is also preferably based on wheel speed. In an active braking mode, a heating effect is provided based at least on sensed wheel speed. If no brake pressure signal is available, the heating effect is further based on vehicle deceleration. The heating effects for front and rear brake units are relatively compensated for differences in heat generation due to load shifts during braking, the compensation being preferably based on vehicle deceleration. The brake rotor temperature estimation is realized in a programmed digital computer but does not use computer resource hungry exponential functions.
