A two-dimensional image projection device using array of micromirror array lenses and a random scanning technique is invented. Using the random scanning technique, the light efficiency is nearly doubled than that of the prior art. The invention makes a brighter and less power consuming display device possible. Because each micromirror array lens of array of micromirror array lenses can scan whole image plane, a fast self diagnosis and correction technique can be introduced in displaying device. The Self diagnosis and correction technique makes display device to maintain image quality even a few tens percent of micromirrors do not work properly. Owing to the scanning characteristics of micromirror array lens, the image projection device can express the same number of pixels image with less number of micromirrors than the prior art. This also enables small sized two-dimensional image projector, which can be incorporated in portable electronic equipments.

A dedicated device for detection of vascular shunts can include a first chamber, a second chamber, and a third chamber. The first chamber can be configured to hold liquid, the second chamber to hold gas, and the third chamber can be in communication with the first and second chambers. The third chamber can include small-scale geometric features configured to produce gas bubbles as liquid from the first chamber and gas from the second chamber simultaneously flow into the third chamber. The device can also include a device opening in communication with the third chamber such that a mixture of liquid and gas bubbles can flow out of the device opening. The device can also include a plunger configured to force the liquid and the gas simultaneously from the first and second chambers, through the third chamber to mix with each other and produce bubbles, and further through the device opening.

The present invention is directed to a system and method for pasteurizing milk and colostrum for feeding to calves. The system includes a vat for storing milk or colostrum, a circulation pump and piping system, a heat exchanger for adjusting and / or maintaining milk temperature, and an ultraviolet light pasteurizing unit (“UV reactor”) that treats the milk without damaging important immunoglobulins.

A control method is used with a control system to control a screw pump. The control system includes an electric motor and a motor drive. The control method includes following steps. Firstly, a DC bus voltage is monitored. If the DC bus voltage is smaller than a first threshold value, a potential energy stored in the pump screw and released by a backspin action is converted into a regenerative electrical energy so as to maintain a normal operation of the motor drive. Then, the motor drive drives the electric motor to control the backspin action of the screw pump according to a backspin torque limit strategy. If the electrical power from the power source is not restored and the level of a reverse regenerative torque is smaller than a preset torque value, the backspin action of the screw pump is stopped freely.

A product and a method employing a block having a downwardly angled front surface suitable for covering the top surface of a continuous geared door hinge after the door is installed in a frame. The block has one or more recessed counter bored holes in the front surface to accommodate security screws without compromising the angle of the front surface.

The invention is an improved cementitious mixture used to form structural components that are strong, lightweight, heat and fire resistant, and very economical to produce. The material includes a mixture of cement, water, ribbon-like virgin polyethylene strips and aggregate materials. The aggregate preferably includes recycled industrial waste products. Examples of these industrial wastes include shredded tires, wood by-products, waste coal combustion by-products, recycled waste gypsum products, recycled industrial foundry sand, and waste foam products such a Styrofoam. This new cementitious material is strong and lightweight. It has a lower thermal conductivity than conventional concrete and therefore improved insulative properties. The use of industrial recyclables not only enhances the performance characteristics of the components made from this material but aids in maintaining the environment by providing a practical use for industrial waste.

The present invention relates to a smart pipette for bio-cell manipulation which can freely change orientation of a bio-cell subject to the manipulation by using mechanical friction and applying instantaneous impact when penetrating the subject bio-cell while receiving real-time feedback of force / torque information of the bio-cell. Further, the present invention relates to a bio-cell manipulation method and system using a smart pipette, through which a bio-cell may be manipulated upon the application of the force / torque information generated during the cell manipulation to the smart pipette control. According to the present invention, injection position can be recognized precisely and conveniently regardless of the proficiency of the manipulating person. Thus, the bio-cell manipulation may be automated. Further, the smart pipette quantifies force / torque information feed-backed through the sensor unit and compares it with data acquired in advance through experiments on the same bio-cell. Further, through conducting impact driving when necessary, the present invention makes it possible to conduct bio-cell manipulation with minimum physical damage.
