Abstract: A light beam can be steered using a non-mechanical beam steerer structure. For example, a combination of sub-aperture and full-aperture beam steering structures can be used (e.g., corresponding to regions of controlled variation in an index of refraction). The sub-aperture elements can include tapered structures defining a saw-tooth or triangular footprint in the plane in which the in-plane steering is performed. Respective rows of sub-aperture tapered structures can be configured to controllably steer the light beam in the first in-plane direction, wherein at least one row of sub-aperture tapered structures defines a first base region edge that is tipped at a first specified in-plane angle relative to a second base region edge defined by another row. Use of the tipped configuration can simplify a configuration of the beam steerer structure, such as allowing a configuration lacking a compensation plate at the input.

Abstract: A sandwich stacker for grasping, rotating and stacking one half of a bisected sandwich on the other half. The stacker includes a half-sandwich gripper. A selectively actuable rotator is coupled to the gripper. The gripper is adapted to releasably hold a first half-sandwich of a bisected sandwich. The rotator selectively rotates the gripper about a first axis of rotation for stacking the first half-sandwich on the other half of the sandwich. The stacker is adapted to be coupled to a positioning device, such as a robotic arm. The rotator may be mounted on the stacker or on the positioning device. The first axis of rotation may be through a center of mass of the first half-sandwich when held by the gripper, or through a cut-line bisecting the bisected sandwich when the first half-sandwich is first held by the gripper.

Abstract: Methods and systems are provided for using compression heating to heat a cylinder piston before cylinder combustion is resumed. Cylinder heating is achieved using combinations of slow unfueled engine rotation where the engine cylinders are heated via compression stroke heating, and slow compressor rotation where the cylinders are heated via compression heating. One or more intake or exhaust heaters may be concurrently operated to expedite cylinder heating.

Abstract: An electrical isolator includes a flexible non-electrically conductive membrane and an inelastic flexible dielectric member journalled in the membrane and extending from the first end of the membrane to the second end of the membrane. First and second couplings are mounted to the ends of the dielectric member. The ends of the membrane are mated in sealed engagement with the couplings so as to fluidically seal the ends of the membrane and the dielectric member within the membrane. The membrane is filled with a dielectric fluid so as to displace any air in the membrane and the dielectric member. The couplings are adapted to couple to objects at opposite ends of the electrical isolator.

Abstract: A tray for positioning in an exit path of a bee hive comprises a base, a bee entrance end, and a bee exit end. Spaced apart side walls extend upwardly from the base. The sidewalls extend generally lengthwise between the bee entrance end and bee exit end. A plurality of posts extend upwardly from the base and are positioned between the bee entrance end and the bee exit end. The posts are generally circular in cross-section. The posts act as obstacles around which the bees must walk to reach the bee exit end from the bee entrance end.

Abstract: A liquid crystal waveguide (LCW) can include actively controlled incoupling of light into a LCW, such as by using a voltage-controlled electrode to actively vary a property of an LC material arranged to affect the incoupling of light into the LCW. Actively varying light incoupling into the LCW can be used, for example, such as for calibration or compensation or to provide closed-loop feedback such as to stabilize the amount of light into the LCW while accommodating or reducing sensitivity of the LCW to variations in one or more of: input laser light incidence angle, input laser wavelength, LCW or input laser temperature, input laser optical power level, or the like. This can advantageously help improve or maximize light incoupling efficiency, which can improve performance and robustness of the LCW under actual operating conditions. The LCW can be used for, among other things, beamsteering in in-plane and out-of-plane directions.

Abstract: A device for performing a surgical procedure on a knee includes an adjustable femoral portion, a tibial portion and at least one sensor coupled with the femoral and/or tibial portions to sense pressure exerted by the femoral and tibial portions against one another. The femoral portion is adapted for removably coupling with a distal end of a femur to adjust tension in soft tissue adjacent the knee and has at least one positioning feature adapted to move relative to the distal end of the femur as the femoral portion is adjusted, thus helping position a femoral prosthetic on the distal end of the femur. The sensor(s) may be adapted to sense pressure at medial and lateral sides of the knee, and relative pressures may be displayed as data on a visual display. Adjustments to the femoral member may be made to balance pressure at flexion and extension of the knee.

Abstract: An electro-optical beamsteerer can be coupled with other optical structures. For example, such optical structures can be used to shape a beam being steered by the beamsteerer or shape a field-of-regard (FOR) addressable from the perspective of the beamsteerer. Optical elements placed at an output of the LCW can be used as a “spot mapper” to increase or decrease the field of view that can be scanned by a beam steered by the LCW, as an illustrative example, Lenses or other optical elements can also be used to correct distortion in the steered beam distribution across the field of view, such as to provide a “smile corrector.” In a similar manner, optical elements can be placed at an input to the beamsteerer, such as to provide a beam expander to change the size of the beam profile inside the beamsteerer device.

Abstract: In certain embodiments, resource usage in a data retrieval process may be reduced. In some embodiments, a graph query related to a data request may be obtained. The graph query may be transformed into a query set based on a graph data model and patterns of the graph query. Upon generation, the query set may include queries and query operators linking the queries, where the query operators include a first query operator linking first and second queries of the queries or other query operators.

Based on the prediction, the first query operator may be removed from the query set to update the query set. The updated query set may be executed to satisfy the graph query.
