  • Patent number: 10508299
    Abstract: Microfluidic devices are provided for trapping, isolating, and processing single cells. The microfluidic devices include a cell capture chamber having a cell funnel positioned within the cell capture chamber to direct a cell passing through the cell capture chamber towards one or more a cell traps positioned downstream of the funnel to receive a cell flowing. The devices may further include auxiliary chambers integrated with the cell capture chamber for subsequent processing and assaying of the contents of a captured cell. Methods for cell capture and preparation are also provided that include flowing cells through a chamber, funneling the cells towards a cell trap, capturing a predefined number of the cells within the trap, interrupting the flow of cells, flowing a wash solution through the chamber to remove contaminants from the chamber, and sealing the predefined number of cells in the chamber.

  • Publication number: 20120162440
    Abstract: A system and method for testing a set top box includes a test manager module in communication with the set top box having a test script including a bitstream. A bitstream player in communication with the test manager module receives the bitstream and communicates the bitstream to the set top box. The test manager module receives a screen image from the set top box that is generated in response to the bitstream. An optical character recognition module performs optical character recognition to obtain a test text string from the screen image. The test manager module compares the test text string with an expected text string. A report module generates a report in response to comparing.

  • Patent number: 7625296
    Abstract: A directional practice device includes an elongated ball-receiving member disposed on a flat surface and having a slot adapted for receiving a plurality of golf balls, and an upright heel-engaging surface disposed at a side of the ball-receiving member and perpendicular to the flat surface. The heel-engaging surface has a lower end defining a side of a head-traveling path extending along a longitudinal direction. The golf balls can be pushed by a putter head to drop from the slot onto the head-traveling path one at a time. After one of the golf balls drops onto the head-traveling path, the putter head can be moved along the head-traveling path to strike the one of the golf balls in the longitudinal direction in such a manner that the heel of the putter head moves on the heel-engaging surface.

  • Patent number: 7566066
    Abstract: A bicycle rear suspension system has a virtual pivot point that is close to a junction between a chain and a front driving sprocket when a piston rod travels relative to a cylinder body by ¼ to ? of a maximum displacement value, and that moves rearwardly when a rear wheel moves upwardly away from the ground. A line interconnecting an instant center of a rear triangular frame and a contacting point between a rear wheel and the ground forms an angle of about 45° with respect to a horizontal line.

  • Patent number: 7419034
    Abstract: A V-type brake is adapted to slow down or stop a wheel, and includes a pair of first and second brake arms, a brake cable assembly connected to a free end of the second brake arm, and a linkage. The linkage is connected pivotally to a free end of the first brake arm, and is interconnected between the free end of the first brake arm and the brake cable assembly in such a manner that the linkage is in a folded state. The linkage is operable to unfold so as to pivot the free ends of the first and second brake arms away from each other, thereby increasing the distance between brake shoes on the first and second brake arms for removal or remounting of the wheel.

  • Patent number: 6385554
    Abstract: A digital tire pressure gauge with visual and voice response system is disclosed. The digital tire pressure gauge includes a pressure transducer, a pair of switching units, an integrator for generating a triangular waveform signal with an increasing ramp section and a decreasing ramp section, a comparator used to compare the triangular waveform signal of the integrator with a reference signal and then generate an output signal with a wave width corresponding to the increasing ramp section of the output signal of the integrator, a register for temporally storing the output signal of the comparator, a peak value detector, a holding circuit, a counting pulse generating circuit, a counting circuit, and a pressure value output buffer. A display is used to display the pressure value stored in the output buffer. A speech processing circuit is used to generate a speech signal accompanying with the display of the visual pressure value signal displayed on the display.
