Abstract: An integrated, unitary battery pack may be formed and used as part of the structural support for a vehicle frame. The unitary battery pack includes arrays cells having all positive and negative electrical terminals aligned in-plane on a common face of the product assembly. The unitary battery pack includes cooling components for passively or actively cooling the cell arrays. The unitary battery pack is encased in a potting material that allows that forms part of the structure support for the unitary battery pack. The unitary batter pack may be integrated into the vehicle with or without additional support structures.

Abstract: A toy includes a magnetically responsive member, a fulcrum member, a printed circuit board (PCB), a lid covering the PCB, an activation switch, a touch sensor, a motion sensor, an audio transducer, a signal generator and a controller. The flexible PCB includes an electromagnetic coil, and a plurality of light emitting diodes (LEDs). Opening of the lid actuates the activation switch, and in response, the controller controls the signal generator to generate a coil control signal for the electromagnetic coil to produce a magnetic field that interacts with the magnetically responsive member, to induce oscillatory flapping of the PCB. In response to detecting a touch signal from the controller, or a motion signal from the motion sensor, the controller also generates a LED control signal to control illumination of the LEDs while the PCB is flapping, and an audio control signal to control the audio transducer to output sound.

Abstract: An optical module includes an optoelectronic assembly and a heat spreader. The optoelectronic assembly includes a flat, rigid substrate, an array of electrical contacts positioned on a first portion of the substrate, and an optoelectronics assemblage that is electrically connected to the array of contacts and is positioned apart from the array of electrical contacts. The heat spreader is comprised of a thermally conductive material and comprises a second portion that is structurally connected to the first portion and a third portion that is thermally connected to the optoelectronics assemblage.

Abstract: Methods for installing an advertising unit at an installation area of a surface are provided. The installation area is cleaned. One or more holes are formed in the installation area. The adhesive is applied at the installation area. The advertising unit is deposited at the installation area atop the adhesive. A fastener is passed through at least a portion of the advertising unit into each of the one or more holes. The adhesive is cured.

Abstract: A method for installing an advertising unit on a ground surface includes cleaning an installation area located at the ground surface, applying an adhesive at the installation area, depositing the advertising unit at the installation area atop the adhesive, and curing the adhesive. In some embodiments, the advertising unit comprises a back unit having a track which accommodates a cover in a sliding fashion. In some embodiments, the installation area may be excavated to render an upper surface of the advertising unit flush with the surface of the ground when deposited.

Abstract: A suction duct is disposed within a shell and tube heat exchanger. The suction duct is located relatively high and above the tube bundle so as to not entrain liquid or droplets that may be splashing and spraying upward. The suction duct is configured with an area schedule in fluid communication with a flow path inside the suction duct. The flow path is in fluid communication with an outlet of the shell. This is advantageous relative to traditional top of the shell outlets which generally have higher vertical footprints. The area schedule of the suction duct can facilitate and/or maintain relatively smooth vapor flow within the shell. The area schedule can achieve vapor flows that have some uniformity along the length of the shell, which can manage and/or avoid localized vapor flow and/or local currents, such as where high velocity may be present and where entrainment can result.

Abstract: A request to perform a cryptographic operation is received, the request including a first identifier assigned to a key group, the key group comprising a plurality of second identifiers, with the plurality of second identifiers corresponding to a plurality of cryptographic keys. A second identifier is determined, according to a distribution scheme, from the plurality of second identifiers, and the cryptographic operation is performed using a cryptographic key of the plurality of cryptographic keys that corresponds to the second identifier that was determined.

Abstract: Electronically signed data is persistently stored in data storage. After the passage of time, the data may be accessed and presented to a trusted entity for verification of the data. The trusted entity may have access to secret information used to sign the data. The trusted entity may use the secret information to verify an electronic signature of the data. One or more actions may be taken based at least in part on a response provided by the verification system.

Abstract: Systems and methods for lubricant management of a compressor in an HVACR system are disclosed. A heat transfer circuit can utilize a working fluid to provide heating or cooling includes a compressor for compressing the working fluid and a heat source configured to increase a suction temperature of the working fluid entering the compressor. One or more lubricant rheological properties in a compressor system based on measurements taken at or near a bearing cavity of the compressor are determinable. A lubricant reservoir can be in thermal communication with a discharge flow path of the compressor. An internal heat exchanger can be disposed within a compressor for improving viscosity of the lubricant to be cycled back into the compressor. A heater can be located on a fluid line between a lubricant separator and a lubricant inlet. Condenser fans can be controlled.

Abstract: An advertising unit advertising unit includes a back unit adapted to be secured to a parking lot. A cover comprising a transparent or translucent material is mounted to the back unit to define a cavity. The cover is adapted to withstand the weight of a vehicle passing over or resting atop the cover without experiencing fracture or inelastic deformation. An electronic display is positioned within the cavity.

Abstract: An advertising unit includes a transparent or translucent cover. A back unit includes a base as well as first and second side ridges which extend from, and along, side edges of the base. A track defined by the first and second side ridges is configured to receive the cover in a sliding arrangement. The space between said cover and said back unit defines a cavity configured to receive one or more advertisements.

Abstract: Systems and methods for displaying advertisements to occupants of vehicles are disclosed. An electronic display is placed between a transparent or translucent cover and a back unit. A camera captures images which are used to determine vehicle identification information for nearby vehicles. Advertising content is displayed on the electronic display based on the vehicle identification information.
