Abstract: Apparatus and methods for producing ultrashort optical pulses are described. A high-power, solid-state, passively mode-locked laser can be manufactured in a compact module that can be incorporated into a portable instrument. The mode-locked laser can produce sub-50-ps optical pulses at a repetition rates between 200 MHz and 50 MHz, rates suitable for massively parallel data-acquisition. The optical pulses can be used to generate a reference clock signal for synchronizing data-acquisition and signal-processing electronics of the portable instrument.

Abstract: A mount for adjusting a mounting plane is disclosed. The mount comprises a first adjustable device, a second adjustable device and a third adjustable device. A first intersection between the first adjustable device and the second adjustable device forming a first principal axis and a second intersection between the second adjustable device and the third adjustable device forming a second principal axis substantially perpendicular to the first principal axis. The first adjustable device, second adjustable device and third adjustable device rigidly coupled together. The first adjustable device is configurable to be adjusted in a first translational degree of freedom, and substantially constrain the first adjustable device in remaining translational degrees of freedom, wherein adjustment of the first adjustable device in the first translational degree of freedom causes a rotation of the mounting plane about the second principal axis.

Abstract: A combiner assembly for a ceiling mounted projection head up display system for an aircraft cabin has an optical combiner (10), and a support mechanism (30, 32, 35) for supporting the optical combiner to be movable between an operational position and a stowage position, above the user, and laterally displaced, and facing an underside of the projector assembly by means of a lateral component of movement and a rotation component to reach the stowage position under the projector assembly (20). Such a two axis movement can make better use of limited headroom in cabins such as those of small aircraft, by enabling a stowage location offset to one side of the line of sight, while providing sufficient clearance from the user's head and from cabin structure, during the movement and/or when in the storage position.

Abstract: A back-to-back ultra-slim module (USM) includes an inline USM (USMi) connector and a top mount USM (USMt) connector. The back-to-back USM assembly can be made as a double-sided module to allow a stacked module configuration to save system area. The stacked module has a USMi module inline with the system board on one side of the system board, and a USMt module vertically offset from the other side of the system board. The stacked module can have a thermal layer between the USMi module and the USMt module.

Abstract: Techniques for system recovery using a failover processor are disclosed. A first processor, with a first instruction set, is configured to execute operations of a first type; and a second processor, with a second instruction set different from the first instruction set, is configured to execute operations of a second type. A determination is made that the second processor has failed to execute at least one operation of the second type within a particular period of time. Responsive to determining that the second processor has failed to execute at least one operation of the second type within the particular period of time, the first processor is configured to execute both the operations of the first type and the operations of the second type.

Abstract: Some embodiments of the present invention provide virtual configuration systems and methods that overcome some or all of the downfalls of typical approaches by allowing for persistent configuration of an operating system of a host device. A virtual configuration layer may be incorporated into the file system of the host device and executed to modify configuration data stored outside of the file system, without changing the file system. Once the configuration data is modified, it may be used to configure the file system and/or the operating system of the host device when it is loaded by a client device. In some embodiments, the host device may be nonvolatile storage (e.g., a flash drive) embedded into a client device (e.g., a diskless system).

Abstract: Techniques for error handling by a servomechanism are disclosed. The servomechanism determines, based on a first set of values assigned to servomechanism variables, electrical signals for controlling a component during a particular time interval, and applies the electrical signals to move the component. Subsequently, the servomechanism measures values for attributes associated with the component. Based on the measured attribute values, the servomechanism computes a second set of values for the servomechanism variables. Responsive to determining that the measured attribute values are erroneous, the servomechanism refrains from modifying the electrical signals based on the second set of values for the servomechanism variables.
