Abstract: Apparatuses including spark gap structures for electrical overstress (EOS) monitoring or protection, and associated methods, are disclosed. In an aspect, a vertical spark gap device includes a substrate having a horizontal main surface and a plurality of pairs of conductive layers over the horizontal main surface. Different ones of the pairs are separated by different vertical distances such that each pair serves as an arcing electrode pair and different ones of the arcing electrode pairs are configured to arc discharge at different voltages.

Abstract: Systems and methods for controlling the motion of an autonomous are provided. In one example embodiment, a method includes obtaining, by one or more computing devices on-board an autonomous vehicle, state data descriptive of a current state of an object that is proximate to the autonomous vehicle. The method includes determining, by the one or more computing devices, one or more features associated with the object based at least in part on the state data. The method includes determining, by the one or more computing devise, a vehicle action for the autonomous vehicle based at least in part on a machine-learned model and the one or more features associated with the object. The vehicle action includes stopping a motion of the autonomous vehicle or moving the autonomous vehicle past the object.

Abstract: Apparatus and methods for treating tissue with electromagnetic radiation. A handpiece includes a housing and a baffle that divides an interior space of the housing into first and second channels. The housing further includes a first opening and a second opening coupled in fluid communication with the first opening by the first channel. The apparatus further includes a heat-generating element, such as a source of electromagnetic radiation, disposed at least partially in the first channel and an air-moving device coupled with the first channel. The air-moving device is configured to generate a forced flow of cooling air entering at the first opening and exhausted at the second opening. The cooling air receives heat transferred from the heat-generating element, which cools the heat-generating element, and the heated cooling air is exhausted from the second opening in a direction away from the tissue that is being treated with the electromagnetic radiation.

Abstract: A handheld apparatus for delivering optical energy to fractionally resurface skin of a consumer is configured to be used by the non-physician consumer. The handheld apparatus includes a housing dimensioned for manual grasping and manipulation. The housing encloses a laser and an optical pattern generator having a rotatable component with a plurality of reflective segments that rotate through an optical beam from the laser to deflect and divide the optical beam into pulses that propagate from the housing and form a fractional pattern at the skin surface. The handheld apparatus also includes a transducer associated with fins on the rotatable component to generate signals for each pulse of electromagnetic radiation, the signals being monitored by a controller to enable an end of dose indication for the consumer when the treatment is completed.

Abstract: Apparatus for delivering optical energy and, in particular, to a handheld apparatus for use by a non-physician consumer. The handheld apparatus is configured to conduct fractional resurfacing or other cosmetic treatment of the consumer's skin with optical energy.

Abstract: A component device carrier system includes a component device frame, a component device collar, and a clocked gear assembly providing motion in at least two directions. The component device collar is disposed around a component device. The component device collar is received in the component device frame to guide and position the component device. Gears on the component device frame mesh with the clocked gear assembly to enable motion in the at least two directions for positioning and securing the component device and for connecting and disconnecting the component device. A component carrier blade supports and arranges a plurality of component devices in at least one linear array.

Abstract: An ejector mechanism. The ejector mechanism includes an ejector pair, pivotally mounted on a surface of the carrier. Each ejector of the ejector pair comprises an ejector slot that is engageable with an ejector pin that is located on a chassis, which accommodates the carrier. A plurality of gear teeth are configured into each ejector wherein the gear teeth on one ejector engage or disengage with the gear teeth on another ejector as the ejector pair pivotally rotates about a point on the carrier. A handle is affixed to one ejector to facilitate the moving of the ejector pair.

Abstract: A fish filter is provided including a mounting assembly mounted on a fish tank. Also included is a filter situated within the mounting assembly. The filter has filtering material situated therein. At least one vertical pipe extends from the filter on a first side of the filtering material. Further, an output is positioned on a second side of the filtering material. Situated within the fish tank is a pump which is connected to the filter for suctioning water through the vertical pipe and the filtering material.

Abstract: A device which provides an escape route from a fire. In a first aspect, the present invention provides a directional fire hose which enables a person a person, even in a dark and smoke-filled environment caused by a fire, to follow the fire hose in a direction away from the fire and toward safety. In a second aspect, the invention provides a directional carpet which enables a person, even in a dark and smoke-filled environment, to escape from a burning house or building. The invention is particularly useful for volunteer fire-fighters, inexperienced fire-fighters, and crewmen on a seagoing vessel or platform at sea.
