  • Publication number: 20110153068
    Abstract: A method for control of humidity and auto-dispensing of pills in a pill box includes a box having multiple rooms defined therein which are shifted to be in alignment with an outlet. The method controls the humidity in each of the rooms and provides a control unit which controls a transmission unit to proceed a mechanical action to shift the rooms to be in alignment with the outlet according to a time setting signal so as to dispense at least one pill. The method includes a display unit to display time information and provides a reminder to take pills by way of audio and/or light.

  • Publication number: 20090311844
    Abstract: An alignment mark, disposed on a substrate, is provided. The alignment mark includes a first dielectric layer and a metal layer. The first dielectric layer is disposed on the substrate and includes an alignment trench and a contact hole. The metal layer is disposed in the alignment trench and the contact hole, wherein a surface of the metal layer is even with a surface of the first dielectric layer. Because the metal layer and the first dielectric layer have different reflection indexes and different refraction indexes, an alignment light detects the alignment mark according to these differences.

  • Patent number: 7633298
    Abstract: A continuity tester for a lamp, coaxial, plug connector has a receptacle connector with first and second coaxial, annular receptacle contacts at a same axial spacing apart as power and ground contacts of the lamp connector for electrical engagement when plugged therein and, a probe contact engageable with only the power contact. First and second LEDs connect to a battery via first and second parallel circuits. A biasing resistor in the second circuit ensures that battery power is provided to only the first LED when a battery circuit is completed only by electrical engagement of the first contact and the probe contact with the power contact of the male coaxial connector to signal absence of a short circuit and to only the second LED when a circuit is completed also by engagement of the second tester contact with the ground contact of the lamp connector to signal a short circuit.

  • Publication number: 20060194235
    Abstract: The human HLJ1 tumor suppressor gene is herein defined as regulated by promoter, enhancer, and silencer regions. HLJ1 promoter activity and gene expression are inversely correlated with metastatic ability. HLJ1 is highly expressed, and inducible, in cells with low metastatic ability and expressed to a lesser extent in highly metastatic cells. HLJ1 gene expression suppressed the growth of human lung adenocarcinoma cells in vitro, and inhibited tumor growth in vivo. It also impeded the motility of human adenocarcinoma cells and reduced the anchorage-independent growth capacity and invasiveness of metastatic lung adenocarcinoma cells. The degree to which human lung adenocarcinoma patients express HLJ1 predicts their survival prognosis and their probability of relapse.

  • Patent number: 6884095
    Abstract: An adaptor box for mounting a fixture to a low voltage track having a housing containing contacts with one of their ends formed with female contact portions which are arranged on above the other in the housing to provide a common mating axis in the housing connection to a male coax connector of the fixture and other ends forming feet protruding from a mounting head of the housing for connection to respective busses of the low voltage track. Contact separating and locating protuberances are molded on the interior of the housing and an insert molded with additional contact locating and separating protuberances is assembled through a front opening in the housing.

  • Patent number: 6604849
    Abstract: A slurry dilution system with an ultrasonic vibrator capable of diluting slurry in-situ to any desired level of concentration is proposed. Raw slurry and the de-ionized water fed into the slurry dilution system is mixed and homogenized by an ultrasonic vibrator and a mixer. The well-mixed slurry solution is then delivered to a chemical-mechanical polishing station. When the chemical-mechanical station requires slurry of a different concentration, the raw slurry can be diluted to the desired level simply by changing the rate of flow of de-ionized water into the dilution system.

  • Patent number: 6059582
    Abstract: An adaptor box for mounting a fixture to a low voltage lighting track having a channel-form cavity retaining wire busses has a one piece, molded housing with opposite side walls joined by upper, lower and rear walls providing a front opening cavity. A mounting head upstands from the upper wall and is formed with opposed mounting ears. A contact receiving through-passageway having a front, contact insertion opening extends from the housing cavity, vertically through the mounting head between the ears, the upper wall being recessed so that the housing is open at a front and at a top, adjacent the front. A one-piece molded insert has a contact separating rib and a releasable, rotation preventing latching tab portion connected together by a transverse, resilient web hinge. A pair of contacts terminating fixture wires extend through the passageway with free ends exposed for electrical connection to the busses.
