Subsea drilling operations

A method for retrieving a subsea pod from a lower marine riser package platform by connecting a buoyant pod retriever to the subsea pod and raising the subsea pod to the surface. In certain aspects, such a method is accomplished without an interruption of associated subsea drilling operations and / or without disconnecting the lower marine riser package from an associated subsea stack. Such a method, in certain aspects, includes: positioning a retrieval module above the pod container, the retrieval module having a pod holder releasably connected thereto; disconnecting the pod holder from the retrieval module; lowering the pod holder to the pod container and releasably connecting the pod holder to the pod container; releasing the pod container from the subsea lower marine riser platform; raising the pod holder to the retrieval module and releasably connecting the pod holder with the pod container to the retrieval module; and raising the retrieval module with the pod container to a location at the surface. Such pod containers are, in certain aspects, part of a multiply redundant control system.

Preparation method and application of electrochemical micro-fluidic sensing chip

The invention provides a preparation method and the application of an electrochemical micro-fluidic sensing chip. The preparation method comprises the following steps: directly coating an improved glass solution on a commercial standard printed electrode; and performing vacuum plasma treatment on a PDMS (Polydimethylsiloxane) chip with pre-designed pipelines and the printed electrode coated with the glass solution together, and directly bonding the PDMS chip on the commercial standard printed electrode to form a novel electrochemical microfluidic sensing platform. A sensor provided by the invention can perform ultrasensitive detection on various sample analytes in a biological fluid sample, taking the detection of a prostate cancer marker PSA (Prostate-specific Antigen) in human serum as an example, a coulomb amperometry is used for detection, and a result shows that the detection sensitivity can reach 0.84 pg / mL which is improved by two magnitudes than the standardized clinical testing requirement of 0.1 ng / mL, so that the sensor has superhigh detection sensitivity and accuracy, which are higher than those of other electrochemical detection devices, is convenient in operation, and can integrates sample processing, separation and the like on one micro electrochemical microfluidic sensing chip.

Programmable manual hair dryer with multiple functions

The dryer includes in its programmable control circuit a microprocessor to which are connected at least a temperature sensor, a static pressure sensor, a motor revolution sensor, a ion generator, a resistor battery with its selector switches in series, and the respective power circuits of the motor and the air heater aforesaid, in which, in order to optimize the processing route, said microprocessor, after the dryer is turned on and the operating values of parameters, establishes the initial operating configuration at 50% of the value thereof, and then defines continuously, in terms of the ordinary data base, the constant functional conditions, and responds to electric, thermal and mechanical discrepancies being involved with its corrective stabilization, recording, signaling and information by means of a display. The stabilization of the ordinary operation conditions, both of the motor and of the heating resistor is achieved by means of the corresponding sensor, the information from which is channeled towards and from the respective speed and temperature control while the signaling and the information are carried out by connecting the respective control in turn to the corresponding VU meter and the equipment display. The recording of events receives directly the information from sensors and from speed and temperature controls, while from the aforesaid speed and temperature controls the information is sent back to the parameter status verification point.

Amphibious utility cart and transport system incorporating same

InactiveUS20080048417A1Easy to transportEffectively conceals the outdoorsmanAmphibious vehiclesCarriage/perambulator accessoriesCartEngineering
An amphibious utility cart aids an outdoorsman in transporting equipment from home to a hunting site, and may further provide seating. The apparatus comprises framing to which a molded plastic platform is attached. The entire unit is designed to be rolled on land with wheels and to float on water with the buoyant seat platform. The platform, in a lounge chair design, is used as an equipment tote platform while going to a destination, and then as a chair for an outdoorsman or his dog when at the destination. The chair is designed for maximum floatation for water crossings and shallow-water seating. The two wheels provide the rear seating base and two retractable poles extend downward to provide frontal leg braces for a stable seating base. A handle is extended for the cart for either land or water transportation, and slides into the metal frame while in the chair mode.

Operation panel device and image forming apparatus provided therewith

An operation panel device with a display surface is provided with mounted on an image forming apparatus. The operation panel device includes first and second panels that are relatively movable along a plane parallel to the display surface. The first panel is fixed to the image forming apparatus. The second panel is disposed opposite to the image forming apparatus with respect to the first panel. A projection area of the second panel to the plane parallel to the display surface is smaller than a projection area of the first panel. Each of the first and second panels includes a first group of keys disposed in a region that is exposed independent from relative positions of the first and second panels. The first panel includes a second group of keys disposed in a region that is exposed only when the first panel and second panels do not overlap each other.
