US Classification:

405188, 405191, 114322

Abstract:

In various embodiments, an apparatus for use in the recovery of unmanned underwater vehicles includes a recovery vehicle configured to be coupled to a winch via a tether. The recovery vehicle includes one or more sensors for locating the unmanned underwater vehicle, a first mechanical linking device for coupling the recovery vehicle to the unmanned underwater vehicle, and a plurality of steering mechanisms for actively guiding the unmanned underwater vehicle in such a way as to allow the first mechanical linking device to capture the unmanned underwater vehicle by locking onto a second mechanical linking device of the unmanned underwater vehicle.

International Classification:

B01L 3/00

Abstract:

The transfer systems, devices, kits, and methods described here may be used to facilitate the transfer of a material (e.g., a fluid) to or from a donor container, e.g., to or from wells of a donor plate while leaving target agents attached to the wells. The systems may comprise a donor plate, a transfer adapter, and a receiver plate that may be coupled to form a transfer assembly. The transfer adapter may comprise a planar sheet and a plurality of openings, and it may be configured to regulate the flow of fluid out of the wells. The transfer assembly may be placed into a centrifuge, and the fluid transfer force produced by the centrifuge may cause fluid to flow out of the wells of the donor plate, through the openings in the transfer adapter, and into the receiver plate.

International Classification:

B01L 3/00
B01F 11/00
B01F 11/02
G01N 33/50

Abstract:

Described herein are multi-well separation devices configured to allow a composition comprising a target agent to be separated into multiple wells, subdivided, recombined into a single well, and/or re-separated into the same or a different configuration of wells. Also described herein are reagent loading devices configured to simultaneously deliver one or more test agents to a plurality of volumes without having to individually deliver the test agents. Together, these devices allow high throughput parallel processes without repetitive pipetting or liquid handling robotics, though they may also be used separately. Also described herein are kits and systems for chemical or biological assays, as well as methods for using the multi-well separation devices and reagent loading devices described herein.

Abstract:

Devices and methods are provided that permit efficient and selective separation of liquid biological specimens into at least two constituent components to facilitate subsequent quantitative and qualitative analysis on at least one analyte of interest in at least one of the components. The devices generally include one or more sample deposition regions supported on a base. Each sample deposition region includes a separation membrane for separating the liquid biological specimen into two different fractions. The first fraction is trapped by the separation membrane while the second fraction passes through the separation membrane and into a respective collection membrane. The separation and collection membranes are easily separable from the devices and can be utilized for further processing and analysis.

Abstract:

Selectively controllable apparatus for insertion into an ear canal, and related methods of use and operation for behavioral control. In one embodiment, the apparatus includes a body configured for insertion into an ear canal. In one variant, the body includes one or more thermal mechanisms which enable selective increase or decrease of temperature of at least portions of the ear canal so as to implement behavioral control of the user, such as to mitigate cravings for food, alcohol, narcotics, or other potentially deleterious substances. In one variant, a mild nausea or pre-nausea condition is created within the user according to a time-temperature profile so as to induce the aforementioned behavioral modification.

International Classification:

H04R 25/00

Abstract:

Apparatus for protection of the ear and ear canal, and related methods of use and operation. In one embodiment, the apparatus includes a selectively actuated valve which permits a varying or modulated size of aperture to be created by the wearer while the apparatus is in use, so as to accommodate varying functions, such as complete occlusion (e.g., for use in swimming or other acquatic activities such that water can be completely excluded) or partial occlusion (e.g., such that sounds can be heard by the wearer, whether in air or under water). In one implementation, the apparatus is retained within the ear canal of the wearer by virtue of the apparatus' shape and coordination with one or more natural features or contours of the anatomy in the ear region, without having to be inserted more than superficially into the outer portion of the ear canal.

A41D 13/11

Abstract:

Improved personal protective equipment facial wear including, in one embodiment, an at least partly adhesive mask, and one or more adhesive eye shields. In one implementation, the mask avoids significant contact with the delicate periorbital skin of the wearer, yet provides a substantially airtight seal so as to preclude moisture vapor transfer and “fogging” of eyeware or instruments. In another implementation, adherence of the eye shield is at least partially overlapping with the mask and creates an at least partial seal around a perimeter of the eye shield. Further, an at least partial seal is formed around a perimeter of the mask. The mask and eye shield additionally prevent nasal air flow obstruction, and address the problem of skin irritation and attachment during normal facial expression and movement of the wearer.
