摘要:
A system and method for the alignment of an insulation piercing contact within a two piece switch housing with an insulated electrical wires disposed within the housing. The housing is comprised of two halves whereby when the two halves are brought together during assembly, the insulation piercing contact pierces the insulation of the electrical wires and forms an electrical connection between the contact and the wires. Proper alignment between the insulation piercing contact and the insulated electrical wires is ensured by providing extended prongs on one half of the switch housing. On the other half of the switch housing, channels are provided and arranged to slidably engage and mate with the prongs prior to contact of the electrical wires with the piercing contact. The prongs and channels fix the relative alignment of the contact with the wire before piercing occurs and ensures consistent location of the electrical connection formed during assembly of the switch housing.

A fluorescent lampholder with a top portion for supporting a fluorescent lamp and a base portion with a wire opening located on the bottom surface of the base that receives wires without exposing the wires to the exterior surface of a fixture. The lampholder is capable of supporting various types and/or sizes of fluorescent lamps such as “tall”, “medium” and “small” T-8 fluorescent lamps as well as other types and/or sizes of fluorescent lamps.

A four function electrical rocker switch has two single pole, single throw on/off sections having their movable contact arms coupled to a single electrical line and their screw terminal fixed contacts connected to individual circuits. The two switch sections are independently operated. A third rocker switch is a single pole, double throw switch with a center-off position. The third switch can be operated to either of two positions to operate either one of two independent circuits or can be left in the center-off position not engaging either circuit. A five function electrical rocker switch can be made up of one section having a single pole, single throw on/off switch and two sections with single pole, double throw switches which each have a center-off position.

A lamp adapter for receiving a lamp having a conductive threaded portion and an extension with a conductive contact electrically insulated from the conductive threaded portion. The lamp adapter has a body with a top portion and a bottom portion. The top portion has a socket with a threaded sleeve adapted to receive the threaded portion of the lamp, a first lead electrically connected to the threaded sleeve, a cavity located with respect to the threaded sleeve so as to receive the extension of the lamp when the lamp is threaded into the threaded sleeve, a metal contact arm located within the cavity so as to make electrical contact with the conductive contact of the lamp when the lamp is threaded into the threaded sleeve, and a second lead electrically connected to the metal contact arm. The bottom portion has a threaded portion suitable for threading into a mating lamp socket, the threaded portion being electrically insulated from the top portion. The lamp adapter includes a recess located within the cavity and a coil spring disposed with a lower portion within the recess and an upper portion above the recess and within the cavity, wherein the metal contact arm is located in cooperation with the coil spring so as to be biased thereon and make contact with the conductive contact of the lamp when the lamp is threaded into the threaded sleeve. The metal contact arm is located with the cavity so as not to make contact with a conductive electrical contact on a lamp not having an extension.
摘要:
Systems and method for organizing information relating to the design of polymer probe array chips including oligonucleotide array chips. A database model is provided which organizes information interrelating probes on a chip, genomic items investigated by the chip, and sequence information relating to the design of the chip. The model is readily translatable into database languages such as SQL. The database model scales to permit storage of information about large numbers of chips having complex designs.
摘要:
Innovative systems and methods for visualizing information collected from analyzing samples are provided. The samples may include nucleic acids, proteins, or other polymers. Gene expression level as determined from analysis of a nucleic acid sample is one possible analysis result that may be visualized. In one embodiment, a computer system may display the expression levels of multiple genes simultaneously in a way that facilitates user identification of genes whose expression is significant to a characteristic such as disease or resistance to disease. Additionally, the computer system may facilitate display of further information about relevant genes once they are identified.

摘要:
Disclosed are methods for analyzing molecular binding events in which the formation of ligand/antiligand complexes can be directly detected in a mixture without requiring separation of the components of the mixture from each other by measuring bulk properties of the mixture (i.e., properties that have contributions from several or all of the components present in the mixture). Using these techniques, it is possible to screen libraries without labeling either the target antiligand or ligand. The invention also provides a method for determining the strength of ligand/antiligand binding by further analysis of the same signals.
