Abstract: In some embodiments, a head-mounted, near-eye display system comprises a stack of waveguides having integral spacers separating the waveguides. The waveguides may each include diffractive optical elements that are formed simultaneously with the spacers by imprinting. The spacers are disposed on one major surface of each of the waveguides and indentations are provided on an opposite major surface of each of the waveguides. The indentations are sized and positioned to align with the spacers, thereby forming a self-aligned stack of waveguides. Tops of the spacers may be provided with light scattering features, anti-reflective coatings, and/or light absorbing adhesive to prevent light leakage between the waveguides. As seen in a top-down view, the spacers may be elongated along the same axis as the diffractive optical elements. The waveguides may include structures (e.g.

Abstract: A storage gateway serves as an interface between processes on a customer network and a service provider. The storage gateway is located on-premise with the customer processes. To customer processes, it appears that data is stored locally. However, the storage gateway interfaces with a remote storage service to store the data. For cached gateways, the primary data store is a remote data store, while frequently accessed data may be locally cached by the gateway. Reads may be satisfied from the local cache or from virtual data storage; writes are handled so as to appropriately update data blocks in the local cache and/or in virtual data storage. For shadowing gateways, the primary data store is the local data store; reads are passed through to a local data store, and writes are shadowed to virtual data storage as well as being sent to local data store.

Abstract: An optical system can include a mirror that reflects incoming light to a sensor for detection. The position and/or orientation of the mirror can be controlled to reflect incoming light from different locations and/or directions. Position and/or orientation of the mirror may be tracked and/or detected by an optical position sensor. The position sensor can transmit a beam to a reflector on the mirror, and the reflected beam can be received by the position sensor. Characteristics of the reflected beam can be measured to determine the position and/or orientation of the mirror. For example, the beam can be used for interferometric and/or intensity measurements, which can then be correlated with a position and/or orientation of the mirror.

Abstract: A system, as an engine with a crankcase containing oil or a fluid mixed with oil, has a reservoir containing liquid that extends up to a level of the fluid. A dipstick support structure supports a dipstick on it so that the dipstick extends into the fluid past the level of the fluid, and so that the dipstick is manually removable from the dipstick support structure by a user. An electrical system is connected with the dipstick, and the electrical system electrically senses the level of the fluid based on an electrical characteristic of the dipstick that varies with the varying level of the fluid when the dipstick extends into it. The electrical characteristic may be capacitance of the dipstick detected by sequential charging and discharging of the dipstick to produce a square wave electrical signal the frequency of which corresponds to the level of fluid.

Abstract: A computing device detects a press of a global shortcut key simultaneously with a first press and release of a modifier key. In response thereto, an operation is initiated in a non-default display region. The operation might be displaying a user interface element in the non-default display region. The computing device can also detect a second press and release of the modifier key simultaneously with the press of the global shortcut key. In response thereto, the operation can be initiated in a second display region, such as a default display region. The second press and release of the modifier key can be detected within a predetermined period of time following the detection of the first press and release of the modifier key. The operation might be simultaneously initiated in multiple display regions, such as sharing a region that encompasses the non-default display region and one or more other display regions.
