Abstract: A battery pack can include a plurality of battery cells arranged adjacent one another in a row. The battery pack can include a first spacer plate aligned with and positioned adjacent the first cell of the plurality of battery cells, a second spacer plate aligned with and positioned adjacent the last cell of the plurality of battery cells, and a housing enclosing the plurality of battery cells. The housing can include a first sidewall positioned adjacent the first spacer plate and a second sidewall positioned adjacent the second spacer plate such that the plurality of battery cells can be positioned between the first sidewall and the second sidewall. The battery pack can include a cover. A layer of adhesive can be disposed between the battery cells and the cover. Various techniques can be employed to improve the durability of the battery pack.

Abstract: A device includes at least one processor configured to partition a source image including image components into sub-images, each including a corresponding image component of the image components, and process each sub-image to produce a target image to be projected for each sub-image of the sub-images. The device also includes one or more light sources coupled to the at least one processor and configured to project an incident light, and a phase projection-based display device coupled to the at least one processor and optically coupled to the one or more light sources and configured to modulate, based on the target image of each sub-image, the incident light to separately project the sub-images.

Abstract: A regenerative air conditioning system for a vehicle includes a condenser, a compressor, an evaporator subsystem, an expansion valve, and a solenoid controlled expansion valve arranged and coupled together in a direct expansion cooling circuit. The evaporator subsystem has a main evaporator and a storage evaporator. The storage evaporator has a phase change material therein surrounding refrigerant passages in the storage evaporator. The storage evaporator in a charge state when the vehicle is decelerating wherein refrigerant flows through the storage evaporator to cool the phase change material to cause it to change phases to store thermal cooling potential. The storage evaporator in a discharge state when the vehicle is stopped and an engine of the vehicle is off to cool cabin cooling air flowing across the storage evaporator by the phase change material absorbing heat from the cabin cooling air flowing across the storage evaporator.

Abstract: In accordance with one embodiment of the present invention, a data acquisition and control system includes a sample manifold for collecting air samples. The manifold may include twenty-eight discrete sorbent tubes. Each sorbent tube may be sealed within the manifold and the manifold may be removed from the system for sorbent tube analysis. A second manifold may be connected to the system for continued air sampling collection. The system may autonomously collect multiple samples at scheduled or triggered events. The system may also communicate with other systems to form a multi-system monitoring network. The system may also interface and operate with a multitude of sensors and monitors of different types.

Abstract: A rechargeable battery system for a portable electronic device is provided. The system includes a battery pack having a first battery and a second battery. The battery pack is preferably configured to electrically connect one of the first and second batteries to the electronic device in a first position, but requires at least partial detachment from the electronic device and reattachment of the battery pack to the electronic device in a second position, different from the first position, to electrically connect the other of the first and second batteries to the electronic device. The system further includes at least one set of charging terminals on the battery pack for charging the first and second batteries.

Abstract: A lightweight, economical, mass-producible, reusable airfoil can be deployed in an airspace while in or attached to any moving vehicle for the purpose of collecting air samples. A frame has an airfoil shape that provides pressure differentials that preferentially direct particulates and contaminants of differing size and mass to different areas of an absorbent media attached or integral to the frame. The absorbent media are readily detachable from the frame for sanitary and efficient transfer to facilities where the samples can be analyzed.
