  • Patent number: 6664904
    Abstract: A method for recovering a data required to have n consecutive and repetitive bits is disclosed. The data is obtained by converting a sample value sequence into a binary sequence according to a preset value and the data having n−1 consecutive first-level bits and two second-level bits immediately adjacent to two end bits of the n−1 consecutive first-level bits, respectively. The method corrects one of the two second-level bits, which has a corresponding sample value closer to the preset value than the other, into another first-level bit to obtain n consecutive first-level bits. In addition, a device for recovering a data to be decoded is also disclosed.

  • Patent number: 6660995
    Abstract: Apparatus and method for measuring scatterer size in a dense media with only a single fiber for both light delivery and collection are disclosed. White light is used as a source and oscillations of the detected light intensities are measured as a function of wavelength. The maximum and minimum of the oscillations can be used to determine scatterer size for monodisperse distributions of spheres when the refractive indices are known. In addition several properties of the probe relevant to tissue diagnosis are disclosed including the effects of absorption, a broad distribution of scatterers, and the depth probed.

  • Patent number: 6661667
    Abstract: A structure for vertically housing multiple computer systems is disclosed. The structure includes a bottom support member and a top support member substantially parallel to the bottom support member. The top support member is attached to the bottom support member by two side members. Bottom guides are mounted to the bottom support member, and top guides are mounted to the top support member. The top guides are substantially parallel to the bottom guides and are substantially aligned with the bottom guides. A computer system having a top groove and a bottom groove slides into a computer space in between the top support member and the bottom support member by having the top groove align with a top guide and by having the bottom groove align with a bottom guide to provide a fitting relationship. The computer system slides into the computer space to a non-backplaned rear.

  • Patent number: 6653933
    Abstract: An autonomous local area distributed network provides a peer-to-peer network to connect nodes and devices using low cost and low bandwidth communication techniques, thus allowing the network to share node resources and distribute programming tasks across the different nodes. Home appliances and devices such as refrigerators, televisions, light switches, light fixtures, garage door openers, stereos, and the like may be configured as nodes on the peer-to-peer network. Operational programs, referred to as “sequences,” may be distributed across nodes in a network to enable the maximum utilization of available node resources.

  • Patent number: 6637463
    Abstract: Methods and apparatus are presented for controlling fluid flow through flow paths with pressure gradient fluid control. Passive fluid flow barriers may be used to act as valves, thereby allowing the flow of fluids through flow paths to be regulated so as to allow fluids to be introduced via a single channel and subsequently split into multiple channels. Flow through the flow paths can be regulated to allow a series of sister wells or chambers to all fill prior to the fluid flowing beyond any one of the sister wells or chambers. Each flow path may have multiple segments, at least one of which is designed to balance the pressure drops of the flow paths to provide uniform flow of fluids through the flow paths. The configurations of the wells may also be modified by adding vents or flow dividers to enhance fluid flushing and gas removal capability.

  • Patent number: 6619175
    Abstract: A V-cutter for use in forming V-shaped grooves (3) on a light guide panel (1) of the backlight unit for a liquid crystal display (LCD) is disclosed. The V-cutter may include a Z-axis lift piece (7) and a W-axis lift piece (8), each of which has a pin kit (10a, 10b) with a plurality of pins (9a, 9b) attached at the bottom thereof. The pins (9a, 9b) are preferably equal in number and spacing to the V-shaped grooves (3) to be formed. The lift pieces (7, 8) may be vertically actuated by a Z-axis controller (5) and a W-axis controller (6). The light guide panel (1) is preferably fixtured to a table (11). The lift pieces (7, 8) are configured to move with respect to the table (11) so that, through successive X-axis and Y-axis operations, the V-shaped grooves can be formed in perpendicular directions with only two reciprocating motions. As a result, the manufacturing cost of the light guide panels (1) is reduced.

  • Patent number: 6615856
    Abstract: A method of controlling fluid flow within a microfluidic circuit using external valves and pumps connected to the circuit is disclosed. The external valves and pumps, which are not a part of the microfluidic substrate, control fluid pumping pressure and the displacement of air out of the fluid circuit as fluid enters into the circuit. If a valve is closed, air cannot be displaced out of circuit, which creates a pneumatic barrier that prevents fluid from advancing within the circuit (under normal operating pressures). Applications of this method of fluid control are explained.
