Image processing performed on images captured with image capture devices may be used to improve upon some of the problems with images captured from devices, including images captured from devices with larger aperture lenses, and, in some particular examples, mobile devices with larger aperture lenses. Multiple images may be captured by the capture device and processing applied to generate a single image through fusing of the multiple images. One potential benefit obtained with fusion of multiple images is a single image with an effective depth of focus (DOF) larger than that available in a single image obtained from the capture device. The DOF of the fused image may be larger than a single image and/or may include multiple distinct in-focus focal distances, whereas a single image from a single capture device has only a single in-focus focal distance.

Mist based humidification systems are employed in numerous environments. However, such systems are typically small portable units whilst it would be beneficial to employ ultrasonic based mist humidifiers in larger environments. However, these environments introduce additional requirements such as reducing the emission/distribution of condensed water as droplets from the humidifier, allowing independent placement of the mist generator from the mist distribution element(s), and the requirement to “throw” the mist a reasonable distance into the environment rather than relying upon the circulation within the environment to achieve distribution. Embodiments of the invention address these issues whilst also supporting modular humidification systems operating at multiple capacities.

Vehicle designers are largely walking away from internal-combustion engines to battery and electric motors. Until infrastructure is developed to support total electrification, hybrid-electric vehicles (HEVs) which include both an internal combustion engine and an electric machine are a step toward electrification and higher system fuel efficiency while retaining the expected vehicle range. To obtain even higher system fuel efficiency combustion modes that provide higher efficiency than spark-ignition (SI) operation can be used in HEVs. A problem with such combustion modes is that they cannot be used over as wide an operating range as SI operation and transitions among modes is slow and cumbersome. By having the ICE installed into a HEV be a multi-combustion mode engine and having the EM to coordinate mode switches to be smooth, the high fuel-efficiency of alternative combustion modes can be exploited while providing smooth operation expected by vehicle users.

Seal elements for establishing fluid seals in a wellbore may be constructed of expandable metal materials. For example, an elongated gland of expandable metal may replace some or all the components in a packing stack of a locking mandrel. The gland may be recessed within the locking mandrel, or narrower than a seal bore of a landing nipple, such that the gland is protected from damage as the locking mandrel passes through landing nipples to reach a target landing nipple. The expandable metal may be induced to chemically react with a brine or other water-based fluid to form metal hydroxides and may thus create a seal with the target landing nipple. Once an intended purpose of the locking mandrel has been achieved, a pressure reversal may be employed to break the seal and/or a mild acid may be introduced to accelerate dissolving of the expandable metal seal.

A multi-layer cap shingle for installation along a ridge, hip, or rake of a roof includes a forward exposure area and a rear headlap area. The multi-layer cap shingle includes at least two layers of shingle material, a top layer and a bottom layer each having opposed edges. The layers are bonded together with patches of lamination adhesive adjacent their opposed edges. The bottom layer is configured with a deformation-absorbing mechanism such as a pair of slots extending from a forward edge rearwardly inboard of the lamination adhesive patches. When the multi-layer cap shingle is bent over a roof ridge, the slots of the bottom layer of shingle material narrow in width to account for the fact that the bottom layer must bend around an arc of slightly smaller radius than the top layer of shingle material. As a result, the opposed edges of the bottom and top layers of shingle material remain aligned and both edges of the top layer are laminated to the bottom layer to increase wind lift resistance of the installed multi-layer cap shingle.
