Abstract:

A nonvolatile memory cell includes a substrate comprising a source, drain, and channel between the source and the drain. A tunnel dielectric layer overlies the channel, and a localized charge storage layer is disposed between the tunnel dielectric layer and a control dielectric layer. A gate electrode has a first surface adjacent to the control dielectric layer, and the first surface includes a midsection and two edge portions. According to one embodiment, the midsection defines a plane, and at least one edge portion extends away from the plane. Preferably, the edge portion extending away from the plane converges toward an opposing second surface of the gate electrode. According to another embodiment, the gate electrode of the nonvolatile memory cell includes a first sublayer and a second sublayer of a different width on the first sublayer.

Abstract:

A system comprising a computer-readable storage medium storing at least one program and a method for determining vehicle overlap with a parking space is presented. The method may include accessing a set of pixel coordinates defining a location of a vehicle within an image, and translating the set of pixel coordinates to a set of global coordinates defining a geospatial location of the vehicle. The method may further include accessing a set of known coordinates of the parking space. The method may further include determining an overlap amount by comparing the global coordinates of the vehicle with the known global coordinates of the parking space, and determining the vehicle overlaps the parking space based on the overlap amount transgressing a threshold overlap amount. The method may further include updating a data object associated with the vehicle to indicate the vehicle overlaps the parking space.
