摘要： A microfluidic device (100) for mixing a liquid L is provided. The microfluidic device (100) comprises a microfluidic chamber (20), having an inlet (30), and arranged to receive the liquid L therein. In use, the microfluidic device (100) is arranged to control translation through the liquid L of a body B introduced therein, wherein the translation of the body B is due to a potential field acting on the body. In this way, the controlled translation of the body B mixes the liquid L in the microfluidic chamber (20).

摘要： Microfluidic devices and nanobiosensors comprising a magnetic nanoparticle attached to a reporter molecule via a release unit for microfluidic-based detection of a target analyte in a biological sample. The nanobiosensors can be magnetically manipulated or guided through the microfluidics channels for incubation with the biological sample, concentration of the nanobiosensors, and detection of target analytes, without having to pump the entire initial sample through a microfluidic channel of the microfluidic device. The magnetic nanoparticles are separated from the reporter molecules before detection and can be re-used.

摘要： Embodiments describe a solid state electronic scanning LIDAR system that includes a scanning focal plane transmitting element and a scanning focal plane receiving element whose operations are synchronized so that the firing sequence of an emitter array in the transmitting element corresponds to a capturing sequence of a photosensor array in the receiving element. During operation, the emitter array can sequentially fire one or more light emitters into a scene and the reflected light can be received by a corresponding set of one or more photosensors through an aperture layer positioned in front of the photosensors. Each light emitter can correspond with an aperture in the aperture layer, and each aperture can correspond to a photosensor in the receiving element such that each light emitter corresponds with a specific photosensor in the receiving element.

摘要： Hybrid optical integration places very strict manufacturing tolerances and performance requirements upon the multiple elements to exploit passive alignment techniques as well as having additional processing requirements. Alternatively, active alignment and soldering/fixing where feasible is also complex and time consuming with 3, 4, or 6-axis control of each element. However, microelectromechanical (MEMS) systems can sense, control, and activate mechanical processes on the micro scale. Beneficially, therefore the inventors combine silicon MEMS based micro-actuators with silicon CMOS control and drive circuits in order to provide alignment of elements within a silicon optical circuit either with respect to each other or with other optical elements hybridly integrated such as compound semiconductor elements. Such inventive MEMS based circuits may be either maintained as active during deployment or powered off once the alignment has been “locked” through an attachment/retention/latching process.

摘要： A system including two components intended to be in friction contact with each other in a given direction, wherein the friction occurs in a functional area, wherein the system is at least one of the two components including, on a surface in the functional area, a texture formed of a series of troughs of rounded shape separated by peaks or a series of bumps of rounded shape separated by troughs, the troughs extending parallel in the given direction and allowing for the evacuation of debris produced by friction and serving as a reservoir for a lubricant. A method for manufacturing at least one component or a mold by the DRIE (deep reactive ion etching) process, wherein surface defects on the sidewalls machined by the DRIE process are used to form the troughs.
