Method of fabricating micro electro mechanical system structure which can be vacuum-packed at wafer level

A method of fabricating a micro electromechanical system (MEMS) structure which can be vacuum-packaged at the wafer level is provided. The method includes the steps of forming a multilayered stack including a signal line on a first wafer; bonding a second wafer to the multilayered stack; polishing the first wafer to a predetermined thickness; forming a MEMS structure in a vacuum area of the first wafer and a pad outside the vacuum area, the MEMS structure and the pad being connected to the signal line; forming a structure in a third wafer to have space corresponding to the vacuum area of the MEMS structure; and bonding the third wafer to the polished surface of the first wafer in a vacuum state. For protection of the structure and maintaining a vacuum level required for operation, the fabricated structure is vacuum-packaged at the wafer level, thereby improving the yield of fabrication. In addition, since a special vacuum packaging process is not necessary, the fabrication can be simplified.

Fluid sensing in a drip tray

A vacuum packaging appliance that detects the amount of liquid present while evacuating and sealing a container is disclosed. The appliance comprises a lid adapted to define a vacuum chamber when it is moved to a closed position relative to a trough in the base of the device. The trough in the lower portion of the device contains a heat-sealing element used to seal the contents of the bag once the vacuum packaging is complete. Disclosed are several embodiments relating to a liquid sensor molded into the walls of the trough. The liquid sensor comprises two electrodes that may be located on opposite sides of the trough or on the same side of the trough. When liquid is present in the trough, the capacitance and resistance between the electrodes changes, thereby sending a signal to a controller indicative of the amount of liquid within the trough while the container is being evacuated. The exact amount of liquid present is compared to a predetermined level of liquid. A vacuum pump controller may suspend operations if the amount of detected liquid exceeds a predetermined amount. The heat-sealing element is also controlled in accordance with the amount of liquid sensed in the trough. The amount of liquid sensed is also indicated to the operator.

Vacuum packed inflatable stretcher with frangible overwrap and method of deploying same

Disclosed is an inflatable stretcher. The stretcher is stored in a deflated state within a frangible outer covering. A lanyard is connected to the internal gas vessel via an “external to internal” mechanical link which does not violate the vacuum seal of the stretcher's outer covering. Pulling the lanyard activates the vessel to rapidly inflate the stretcher. This inflation causes an overpressure condition within the covering that results in a progressive tear and the eventual separation of the outer covering. The stretcher can thereafter be used to transport a patient.

Process for the filleting, treating, packaging, freezing, and thawing of varying types of tuna and other pelagic species

A method of treating fish to maintain freshness after freezing and thawing. A whole fish is chilled and cut into four loins, each with two flat sides forming a corner. The loins are chilled and either sliced cross sectionally to form steaks or sliced parallel to one of the flat sides to form sashimi slabs. If sashimi slabs are formed, the slabs are then preferably dipped in a warm flavor enhancing solution. The steaks or slabs are then sealed in non-permeable bags, preferably in a "puzzle pack" configuration that maximizes density and minimizes interstices. The bag with the steaks or sashimi slabs is then submerged in a brine solution. A treatment gas is then injected into the bag. After a treatment time, the gas is removed and the bag is vacuum packed. The bags are then frozen for shipping and storage. When needed, the bags can be thawed in a brine solution.
