US Classification:

607118, 607 45

Abstract:

A neural probe device includes a housing configured to receive a nerve fiber of a subject and an anchor disposed within the housing and configured to fix the nerve fiber relative to the housing. The device further includes a plurality of actuatable, moveable electrodes disposed in the housing along a length of the nerve fiber, each moveable electrode comprising a plurality of projections containing one or more electrodes thereon, wherein actuation of the moveable electrode causes the moveable electrode to move generally transverse to a long axis of the nerve fiber and penetrate the nerve fiber with the plurality of projections. The device is also optionally configured to inject a growth factor into the nerve fiber to maintain the viability of the nerve fiber.

Abstract:

A device for identifying infection by the malaria parasite includes a microfluidic device having an inlet and an outlet and a diagnostic channel interposed between the inlet and the outlet. The diagnostic channel includes a contact surface and a sample pump configured to pump a RBC-containing sample into the inlet. The contact surface may be at least one of hydrophilic and roughened. Malaria infected RBCs (miRBCs) interact with the contact surface and become immobilized thereon whereas non-infected RBCs continue to flow downstream in the diagnostic channel.

William TANG - Covina CA, US

International Classification:

G06F 3/12
G01C 21/20

Abstract:

A system and method for identification and location of user identified, feature specific printers works in conjunction with a user's smartphone or tablet computer. A user inputs their desired printer features into their device, and a listing of candidate printers within a search perimeter is rendered. A distance between the user device and each candidate printer is calculated from a determined location user device relative to locations of each of the candidate printers. The user selects their desired printer from the candidates, and directions for the user to walk to the selected printer are generated and displayed.

Assignee:

International Classification:

F04C 2/16
F04C 15/00
F04C 13/00

Abstract:

Overheating of a process liquid retained in a reservoir of a multiphase pump during extended gas slugs is avoided by circulating a cooling liquid in thermal contact with a process liquid through an external cooling apparatus, which can include a heat exchanger. In some embodiments, process liquid from the reservoir is circulated through the cooling loop, while in other embodiments a separate cooling liquid is circulated between a reservoir heat exchanger and the external cooling apparatus. The liquid in the cooling loop can be circulated by a separate cooling pump, or process liquid can be circulated through the cooling loop due to a pressure differential between an inlet and an outlet of the cooling loop within the multiphase pump. The multiphase pump can be a twin screw pump, and the reservoir can be formed between outer and inner casings of the multiphase pump.

B01D 29/66
B01D 35/26
F04C 2/16

Abstract:

An apparatus and method prevent entrained solids from entering a pump by directing a process stream through an active upstream filter that removes the solids, and then through a downstream idle filter where the process stream purges the filter of previously retained solids. The flow path is periodically switched to exchange the roles of the filters, so that none of the filters is saturated, and the solids remain in the process flow but bypass the pump. Any need for a low pressure destination for purged solids and purging fluid and/or any environmental impact of dumping process fluid and solids into the environment is thereby avoided. Partially opened valves can be used to divert only part of the downstream flow for filter purging. Selectable paths can be included for which no filters are purged. The downstream flow can be divided and used to simultaneously purge a plurality of idle filters.
