The present invention relates to a microrefractometer using defocusing imaging. The refractometer includes: a target in which a target micrometer and a reference fluid, an index of refraction of which is known, are positioned; an objective lens receiving light that has been emitted from a light source and passed through the target; an aperture including a plurality of pin holes which divide an optical path of the light having passed through the objective lens; and a camera photographing defocused images formed on an image plane of the refractometer by the light having passed through the aperture.

A sensor for measuring heat generated from cells, including a thermopile manufactured by surface-micromachining technology, and a microfluidic flow-channel structure for mixing cells with medium and dividing the mixture into cells and medium. Medium and cells are uniformly mixed using a micro-mixer. The mixture is separated into a medium microfluid and a cell microfluid using the Zweifach-Fung effect, after which signals measured in the two microfluids are amplified. The difference between the two signal values determines the amount of heat generated from the cells. The influence of noise caused by a change in external environment is eliminated. Convection heat dissipation caused by fluid flow is minimized. The sensor accurately measures the amount of heat generated from cells flowing in the microfluidic flow-channel. Diseases such as cancer are diagnosed using the difference between the measured amount of heat generated from cells and the standard amount of heat generated from normal cells.

The present invention is a location tracking method installed or embedded in an electronic device as an agent (for example software, firmware or hardware) that determines the location of the device and sends the location information to an owner's email address directly or via a relay agent in a fault-tolerant and privacy-safe manner. Others can not track whereabouts of the owner and the device. The method does not use any monitoring server (or system) and does not use any personally identifying information to protect privacy of the device owner. The system's enhanced privacy, multiple redundant location determination and location information delivery system that overcomes such common problems as: the need for a dedicated location monitoring system; location determination errors; IP address blocking; port blocking; owner's email account failure; and other obstacles that hinder location information delivery to an owner's email address. Additionally this system has an optional data destruction function that can be activated by a remote control program to destroy data on the device once the device establishes connection with the remote control program in an owner's computer.

A method of processing book orders. A vendor establishes a plurality of distribution centers located in different parts of the world, as well as a receiving center. A plurality of customers places book orders. The vendor receives the book orders and sorts them by book sellers. After sorting, the vendor creates aggregated orders and places them with the corresponding book sellers. This provides savings on shipping costs because a publisher or a wholesaler would ship large quantities of books rather than shipping books individually. The aggregated orders are received at the receiving center and sorted by the distribution centers corresponding to the book orders, creating bulk shipments. The bulk shipments are then shipped to the corresponding distribution centers. This provides savings on shipping costs because books are shipped from the receiving center to the distribution centers in large quantities rather than shipping books individually. The book orders are then shipped from the distribution centers to the individual customers.

The present invention relates to a cell lysis apparatus and a manufacturing method thereof, and more particularly, to a cell lysis apparatus, which mechanically performs cell lysis, and a manufacturing method thereof. The cell lysis apparatus includes: an inlet port through which fluid containing cells is supplied; a fluid channel defining a passage through which the cell containing fluid supplied from the inlet port flows; a nano blade array including a plurality of nano blades having pointed leading ends and arranged such that the pointed leading ends of the nano blades are oriented in a direction of the fluid supplied through the inlet port to disrupt the cells passing therethrough; and an outlet port through which the disrupted cells and the fluid are discharged.

A mobile terminal executes a navigation function by receiving Transport Protocol Experts Group (TPEG) traffic information through a Digital Multimedia Broadcasting (DMB) network. This DMB-based mobile terminal receives and decodes TPEG data at a separate second processor different from a conventional first processor. Further, the DMB-based mobile terminal may execute a calculation of an optimum route at the second processor. The terminal and a related method reduce the processing load of the first processor, which causes a decrease in the response time to a user's navigation request and improves a user's convenience.
摘要:
One aspect of the present invention relates to a method of coating a surface, comprising sequentially depositing on a surface, under pH-controlled conditions, alternating layers of polymers to provide a coated surface, wherein a first polymer is selected from the group consisting of pH dependent cationic polyelectrolytes and neutral polymers, and a second polymer is selected from the group consisting of anionic polyelectrolytes, thereby permitting or preventing cell adhesion to said coated surface. In certain embodiments, the aforementioned method provides a coated surface to which cell adhesion is permitted. In certain embodiments, the aforementioned method provides a coated surface to which cell adhesion is prevented. Another aspect of the present invention relates to a method of rendering a surface cytophilic, comprising the step of coating a surface with a polyelectrolyte multilayer film, which film swells to less than or equal to about 150% of its original thickness when exposed to an aqueous medium. Another aspect of the present invention relates to a method of rendering a surface cytophobic, comprising the step of coating a surface with a polyelectrolyte multilayer film, which film swells to greater than or equal to about 200% of its original thickness when exposed to an aqueous medium.
摘要:
A wheeled luggage case (1) has a single telescoping handle arm assembly (10) and a cantilevered handle grip (11) which is rotatably attached to the top end (13) of the handle arm assembly, such that the plane of rotation of the grip is approximately parallel to the rolling direction of the luggage case. The cantilevered handle grip (11) rotates from a position approximately perpendicular to the telescoping handle arm assembly (10) to a position approximately 30° below the horizontal, and a resilient element is provided which urges the grip to rotate downwardly while in use. The invention provides an ergonomically comfortable wheeled luggage case by allowing the user to grasp the grip in a natural position and, simultaneously, increasing the amount of leverage available to prevent the luggage case from tipping over when it is rolled over uneven ground. Further, the resilient element distributes the weight of the luggage case evenly across the user's hand.
