Abstract: Devices and methods for the manipulation and handling of light blocking masks suitable for controlled illumination of the wells of multi-well test plates are described. Such controlled illumination can be used to generate simple or complex three dimensional forms within the wells when used in combination with suitable photoactivatable polymer or gel precursors. Light blocking masks of the inventive concept can include features that stabilize or grip a multiwell plate when in use. Such masks can have apertures having a fixed configuration, or can have apertures with transient or changeable configurations.

Abstract: The present invention relates to a negative pressure wound closure system and methods for using such a system. Preferred embodiments of the invention facilitate closure of the wound by preferentially contracting to provide for movement of the tissue. Preferred embodiments can utilize tissue grasping elements to apply a wound closing force to the tissue.

Abstract: A portable wireless traffic-control signal system for safely directing vehicle and/or pedestrian traffic is disclosed. In a preferred embodiment, it includes a base, an adjustable-height vertical support, and a display module capable of displaying words and/or images. In a preferred embodiment, the system includes remote control capability so that safety personnel (e.g., police officer or crossing guard) may control the system from a location safely out of the path of traffic.

Abstract: An apparatus for controlling water flow from an irrigation ditch can include a first conduit connecting portion adapted to be coupled with a first conduit, the first conduit having an opening for receiving water from the irrigation ditch, a second conduit connecting portion adapted to be coupled with a second conduit, the first and second conduit connecting portions being adapted to be arranged for allowing passage of the received water from the first conduit to the second conduit. In a first operating configuration, the first conduit connecting portion is positioned for elevating the opening of the first conduit at an elevated position to prevent water from being received into the opening. In a second operating configuration, the first conduit connecting portion is positioned for lowering the opening of the first conduit to allow water to be received into the opening.

Preferred embodiments can utilize tissue grasping elements to apply a wound closing force to the tissue.

Abstract: Methods and devices for controlling a camera on a vehicle may include determining a duty status of a driver of the vehicle. The methods and devices may also include controlling a recording status of at least one camera of a camera system on the vehicle based on the duty status.

Abstract: Devices and systems for analyzing biological samples are provided. Devices include a hollow body extending from a first end to a second end. The body defines a sample collecting portion. A first opening at the first end of the body is operable to receive a source of negative pressure and a second opening at the second end of the body is operable to receive a biological sample. The body also includes an optically transparent region disposed in a region corresponding to the sample collecting portion, the optically transparent region being configured to transmit electromagnetic radiation therethrough from an imaging device capable of imaging the biological sample when disposed in the sample collecting portion.

Abstract: Embodiments relate generally to systems and methods for providing a seal between an expansion plug and an opening in a load pin. A load pin may comprise a strain gauge located within an opening in a body of the load pin; an expansion plug configured to seal with the opening, covering the strain gauge; and a sealing material attached to at least a portion of the expansion plug configured to seal between the expansion plug and the opening. A method may comprise selecting a sealing material configured to prevent damage to the expansion plug from the external environment, based on the environment in which the expansion plug will be used; applying the sealing material to at least a portion of the expansion plug; vulcanizing the sealing material to the expansion plug to combine the two elements; and inserting the expansion plug into the opening.

Abstract: A vascular impedance measuring device may comprise a processing component capable of processing raw pressure and flow wave data and a pressure measuring component capable of providing pressure wave data from a specified point in a vessel and forwarding the pressure wave data to the processing component. The device may further include a flow measuring component capable of providing flow wave data from the specified point or a point near the specified point in the vessel and forwarding the flow wave data to the processing component. The processing component processes the raw pressure and flow wave data to produce an estimation of vascular impedance of the vessel from the specified point of measure and may provide data to a feedback system for therapy.

Abstract: A charging device is configured to deliver power to a portable, power-consuming device, having a profile sensor which can detect information relating to the identity of power-consuming device to which the charging device is connected and may also have a communication channel configured to transmit said information to a remote server. In use, data can be collected or aggregated relating to power-consuming devices by connecting the charging device to the portable power-consuming device; sensing, by a profile sensor in the charging device, information relating to the identity of the power-consuming device; and transmitting the information to a remote server over a communication channel. Collected data may, for example, be used to identify when fuel for a charging device may need replenishment.

Abstract: The present invention relates to a negative pressure wound closure system and methods for using such a system. Preferred embodiments of the invention facilitate closure of the wound by preferentially contracting to provide for movement of the tissue. Preferred embodiments can utilize tissue securing portions that aid in securing the invention within a wound.

Abstract: A modular assembly for measuring forces on a structure. The structure may contain a strain gage module that is insertable in a cavity or hole in the structure. There may be numerous structures that can contain a strain gage module. These structures may have various configurations, sizes, and shapes. Despite the various configurations, sizes and shapes, the structures may have cavities or holes of the same size that accept strain gage modules of the same size. Modules of the same size may be easier and less expensive by being produced in multiple quantities, than modules of various sizes. An electronics module may be attached to or separate from the structure. Electronics modules may also be the same items for various structures and be produced in multiple quantities. One example application of the structure may be a strain gage instrumented load pin replacing a standard connecting pin.
