摘要:
A highly-efficient thermal inkjet printhead. The printhead includes a primary layer of polycrystalline silicon (preferably doped) having at least one portion thereof which functions as an ink expulsion resistor. Positioned over and above the primary layer is a secondary layer of material having at least one section produced from a selected metal silicide compound and at least another section fabricated from undoped polycrystalline silicon. The metal silicide-containing section functions as an interconnect structure and is operatively connected to the resistor in the primary layer (which is positioned beneath the secondary layer). The undoped polycrystalline silicon section is at least partially aligned over and above the resistor. As a result, the resistor is “buried” beneath the secondary layer and the various portions thereof. This system provides improved reliability, greater dimensional simplicity, optimized electrical/thermal properties, and superior versatility.
摘要:
A highly-efficient thermal inkjet printhead. The printhead includes at least one doped polycrystalline silicon resistor which communicates with an external signal source using a unique interconnection system. Specifically, a primary layer of electrically conductive material (optimally a metal silicide) is connected to the resistor. An additional layer of electrically conductive material is attached to and above the primary layer. The additional layer terminates at a position which is spaced outwardly and apart from the resistor to form a gap therebetween. However, the underlying primary layer electrically links the additional layer to the resistor. Alternatively, a dielectric layer is attached to and above the primary layer, with the additional layer being secured to the dielectric layer. At least one electrically conductive contact member is provided within the dielectric layer to link the primary and additional layers. These systems provide improved reliability, greater dimensional simplicity, and optimized electrical/thermal properties.

摘要:
The present invention provides miniaturized instruments for conducting chemical reactions where control of the reaction temperature is desired or required. Specifically, this invention provides chips and optical systems for performing and monitoring temperature-dependent chemical reactions. The apparatus and methods embodied in the present invention are particularly useful for high-throughput and low-cost amplification of nucleic acids.
摘要:
Apparatus, systems, chips, and methods of performing a large number of simultaneous chemical reactions are provided herein. The chips of the invention comprise addressable units that can be addressed according to the temperature of the reaction to be run. The subject apparatus, systems, and chips are particularly suited for performing polymerase chain reactions on thousands of nucleic acid sequences, up to and including sequences of an entire genome of an organism of interest.

Described herein are environmentally isolated tissue culture devices that may be used for cell culture, as well as systems including these devices and methods for using them. These devices may include control features for regulating the micro-environment within a well or wells of the device. For example, on-board features may regulate the temperature, humidity, pH, media level, media composition, CO2/O2/N2 levels, drug concentration, cell density, byproduct (or product) production, and mixing of materials within the chamber. Material may be added to or withdrawn from the wells of the device without opening the device. Also described herein are controllers for analyzing and controlling the micro- environment within the well. Thus, the plates described herein may be used without requiring a separate incubator, allowing cells to be analyzed (e.g., imaged) continuously, allowing real-time reactions while monitoring under a microscope for hours, days or even weeks.

Disclosed herein is a computer implemented method and system for providing increased health insurance benefits to employees of business entities for an insurance premium charge. A third party collects health plan requirements and critical health information from the employees. The third party then proposes health plans from health insurance companies to the business entities. Each employee of the business entities chooses a health plan. The third party combines the employees into groups based on the chosen health plans and geographic location of the business entities. The third party negotiates with the health insurance companies regarding health insurance benefits and insurance premium charges offered for the combined employee groups. Authorized personnel may be provided access to the critical health information of the employees. The access to the critical health information improves quality of health care provided to the employees by the attending physicians and reduces the liability to health insurance companies.
