摘要： Disclosed are a motion-sensitive field effect transistor (MSFET), a motion detection system, and a method. The MSFET includes a gate structure with a reservoir containing conductive fluid and gate electrode(s). Given position(s) of the gate electrode(s) and a fill level of the fluid within the reservoir, contact between the gate electrode(s) and the fluid depends upon the orientation the MSFET channel region relative to the top surface of the conductive fluid and the orientation of the MSFET channel region relative to the top surface of the conductive fluid depends upon position in space and/or movement of the MSFET and, particularly, position in space and/or movement of the chip on which the MSFET is formed. An electrical property of the MSFET in response to specific bias conditions varies depending on whether or not or to what extent the gate electrode(s) contact the fluid and is, thus, measurable for sensing chip motion.

摘要： A level including level vial(s) having enhanced visibility are provided. The level may include a level vial including a material that is attracted to the interface or border of a globule within the level vial which improves visibility of the interface. The level may include a solid level indicator having easy to see end surfaces that are generally vertically oriented when in the level position. The end surfaces of the solid level indicator may allow the user to more easily compare the position of the solid level indicator to indicating lines formed on the level vial. The level may include a level vial including a first liquid and an immiscible second liquid forming a globule with the first material. The globule formed from the second material may improve visibility compared to a typical air bubble.

摘要： An alignment tool 1 for use in marking a surface is disclosed. The tool comprises a handle 6, two pairs of longitudinal arms 2,4 and 3,5 each rotatably mounted in the region of their longitudinal centres to a rotational mechanism provided in or on the handle. The rotational mechanism is arranged such that, in use, movement of one of the pairs in a first rotational direction results in movement of the other pair in the counter direction by substantially the same angle. Each of the arms carries at least one movable marking indicator 50, 53. A user-operable locking mechanism is on or associated with the handle, the locking mechanism being configured selectively to prevent and enable rotation of the arms.

摘要： The present invention discloses a laser level, which includes a top surface and a bottom surface parallel to each other, and a main body to be installed with a plurality of vials. One end of said main body has an integrally extended configuration of a base. Said base is pivotally connected to one end of a connector, while the other end of said connector is bound with a laser module, so that the laser module can rotate freely around the pivot between the connector and the base to adjust the projection angle of the laser beam.

摘要： The present disclosure provides a globe clamp with integrated mounting pads which can hold a level while a user adjusts the lighting device to which the globe clamp is coupled. In one example embodiment, the globe clamp includes a clamp body, which includes a top portion, a bottom portion, and an exterior contour. The top portion forms a first internal opening defined by a first inner surface. The bottom portion forms a second internal opening defined by a second inner surface. The exterior contour surrounds the top portion and the bottom portion. The exterior contour comprises at least one recess having a horizontal, flat surface, the recess configured to retain a level.

摘要： Examples of a device for hanging multiple items on a structure are disclosed. The device comprises an elongated body with a planar configuration and a first opening in the body in proximity to one of its ends. The opening is shaped and sized so that it can fit over a hardware, such as a screw or nail, that penetrates into the structure. One or more additional markings are formed in the body at a pre-determined distance from the first opening. The hardware at the first opening holds the end of the device in place so that the body can be placed against the structure and extended in a desired direction to mark position of a next item by registering it with a position of the one of the additional markings.
