Abstract: A network system can communicate with user and provider devices to facilitate the provision of a network-based service. The network system can identify optimal service providers to provide services requested by users. The network can utilize context data in matching service providers with users. In particular, the network system can determine, based on context data associated with a user, whether to perform pre-request matching for that user. A service provider who is pre-request matched with the user can be directed by the network system to relocate via a pre-request relocation direction. When the user submits the service request after the pre-request match, the network system can either automatically transmit an invitation to the pre-request matched service provider or can perform post-request matching to identify an optimal service provider for the user.

Abstract: The present invention is directed to the fabrication and use of phase-change material (PCM) membranes in microvalves for microfluidic systems. The microvalve may be fabricated by using a tissue-sectioning instrument to slice a thin membrane of PCM off of a block of PCM. The membrane may then be sandwiched between a plurality of microfluidic flow sections to act as a microvalve. At room temperature, the membrane may exist in a solid state to act as a zero-leakage seal and microvalve. Applying heat to the membrane may bring the membrane to a melting point, causing it to reach a liquid state. The microvalve in the liquid state may experience a surface tension effect by a material of the microfluidic flow sections, causing it to displace from a flow path and allow a fluid to pass from one microfluidic flow section to another.
