  • Patent number: 9172387
    Abstract: An analog input stage has m differential input channels, wherein m>1. The analog input stage is configured to select one of the m differential input channels and provide an output signal. The analog input stage has n identical selection units each having m differential channel inputs and one differential output, wherein n is at least 2m?1. Each selection unit is operable to be coupled to any of the differential input channels through respective differential multiplexer units, wherein the multiplexor units are driven to select one of the differential input channels and couple the selected differential channel input through a butterfly switch unit with the differential output of the selection unit. The differential output signals of the n selection units are combined whereby unwanted crosstalk from channels other than a selected channel are removed by cancellation.

  • Patent number: 8945916
    Abstract: A device and system for growing of a photosynthetic culture is provided which employs one or a plurality of vertically disposed photopanels having interior cavities configured for holding liquid and the photosynthetic culture such as algae. Interior surfaces are enhanced in size by projections defined by deformation in sidewalls of the photopanels. The projections communicate between the sidewalls also providing structural integrity to the photopanel and allowing for thinner sidewalls and increased light transmission therethrough. The system may employ a support rack and pivotal mount to each such photopanel to allow positioning adjacent to each other in rows. Pivoting during different lighting conditions afforded the racked photopanels provides a manner to reduce light blockage to individual photo panels from adjacent photopanels.

  • Publication number: 20130140425
    Abstract: A device and system for growing a photosynthetic culture is provided which employs one or a plurality of vertically disposed photopanels having an inner chamber configured for holding liquid and the photosynthetic culture such as algae. The inner chamber of the photopanels may have a shape that is defined as well as structurally supported by bridging elements. The photopanels with the bridging elements may be formed as stepped cones and pyramids utilizing common recyclable clear plastic sheets and membranes. The bridging elements also serve to increases the surface area to volume ratio of the inner chamber, expand the surface area exposed to light, alter the hydrodynamics within the photopanel as well as distribute light as light guides to facilitate homogenization of light exposure to individual cells. The bridging elements also have features that allow utilization of direct light beams with shallow grazing angles.

  • Publication number: 20120211211
    Abstract: A heat sink equipped with a vapor chamber includes a heat conduction plate and a vapor chamber. The heat conduction plate has one side formed integrally a plurality of radiation fins and another side with two lateral edges formed respectively and integrally a fastening portion. The two fastening portions are interposed by a recess to bond the vapor chamber. Each fastening portion is fastened to a printed circuit board through at least one screw to allow the vapor chamber to contact a heat generation element. The fastening portion is integrally formed at a desired thickness, thus has sufficient strength to withstand the fastening force of the screw to prevent tight sealing between the vapor chamber and heat generation element affected by deformation of the heat conduction plate. Thereby the vapor chamber can smoothly contact the heat generation element to rapidly transfer heat outside.

  • Publication number: 20120067550
    Abstract: A heat sink structure embedded with a heat pipe includes a heat dissipation seat, at least one heat pipe, a metal-filling adhesive and at least one covering sheet. The heat dissipation seat has a heat absorption surface and a heat dissipation surface. The heat absorption surface has at least one groove to hold the heat pipe and a bonding medium. The groove is covered by the covering sheet. The metal-filling adhesive is filled with the groove to bond the heat pipe and covering sheet through the bonding medium that can increase adhesion force. The covering sheet covers the heat pipe from being damaged during polishing the heat absorption surface to maintain sealing characteristic of the heat pipe. Therefore, the heat pipe can provide rapid heat conduction effect to meet use requirement.

  • Publication number: 20090160240
    Abstract: A one way wheel assembly of the present invention includes a first wheel, a second wheel, and a telescoping device pivotally connected to the first wheel and the second wheel respectively. The telescoping device provides a tolerance that first wheel may move toward the second wheel and touch it. So that, when the first wheel is moved along a direction, away from the second wheel, the first wheel will draw the second wheel through the telescoping device. On the contrary, when the first wheel is moved along an opposite direction, toward the second wheel, the first wheel will touch the second wheel and cause a jam to stop both of the wheels.

  • Patent number: 7367957
    Abstract: A vibration training apparatus includes a base, a swinging link rod module and a driving mechanism. The swinging link rod module installed on the base has a driving mechanism for driving several swinging link rods for a link rod movement. An eccentric transmission shaft driven by a motor drives the swinging link rod module to produce a linear vibration during the swinging process, and matches with the rotation speed of the motor to drive a support stand to produce vertically up-and-down displacements with vibrations of different frequencies. An adjusting device can be installed between the swinging link rod module and the base for changing the swinging amplitude of the swinging link rod module, such that the driving mechanism can drive the swinging link rod module to linearly change the vibration amplitude and achieve a whole-body vibration effect to stimulate internal organs and improve muscle strengths and blood circulations.

  • Publication number: 20070155587
    Abstract: An exerciser includes a resistance mechanism which includes a control unit so that the users can input pre-set programs via a panel to a Micro Control Unit (MCU) so as to drive a driving mechanism. The driving mechanism includes a motor, a reel and a cable reeves through the reel. The reel is driven by the motor so as to pull the cable by a desired force. A load detection device is connected between the cable and the control unit so as to detect the tension of the cable. When the load detection mechanism detects an unusual situation on the cable, the operation of the driving mechanism is stopped or slower to protect the users.
