Abstract: A method and apparatus for a vehicle suspension system gas spring. In one embodiment, a vehicle suspension system gas spring includes a compressible main gas chamber and an additional volume combinable with the main chamber to change a gas spring rate of the system. In one embodiment, a low friction piston seal is created by a flexible seal member.

Abstract: A computing device retrieves a stabilized weight and a weight-based item count for one or more items to be purchased. Responsive to retrieving the stabilized weight, the computing device retrieves an image-based item count and an expected weight based on the image-based item count for the one or more items to be purchased. The computing device selects between authorizing and blocking checkout of the one or more items based on the weight-based item count, the image-based item count, the stabilized weight, and the expected weight.

Abstract: A self-checkout (SCO) terminal in a retail store controls banks of lights to communicate context information to a customer in order to better inform them about various events. The context information may be related to a predetermined event, such as a self-checkout process or an emergency event, and is enhanced using the personal preferences of the customer using the SCO terminal.

Abstract: A linear light fixture with gap filler elements. The fixture comprises two primary structural components: a base and a light engine, which may be removably attached. The base comprises a body with end panels at both ends and is mountable to an external structure. The light engine comprises the light sources, an elongated lens, and any other optical elements that tailor the outgoing light to a particular profile. A gap filler element is disposed between the light engine and the end panels at one or both ends of the base to fill the space between those elements, giving the appearance that the light engine extends continuously to the end panel and eliminating direct imaging of the light sources outside the fixture. External reflectors may also be included to further shape the output beam.

Abstract: A modular troffer-style fixture that is well-suited for use with solid state light sources, such as LEDs, to provide a surface ambient light (SAL). The fixture comprises two structural components: a housing subassembly and a lighting subassembly. These two subassemblies may be removably attached to operate as a singular fixture. Many different lighting subassemblies may be compatible with a single housing subassembly and vice versa. The housing subassembly comprises a body that is mountable to an external structure. The lighting subassembly comprises the light sources and optical elements that tailor the light to achieve a particular profile. Electronics necessary to power and control the light sources may be disposed in the housing subassembly, the lighting subassembly, or both. Various mount mechanisms may be used to attach the fixture to a surface such as a ceiling or a wall. Multiple fixtures can be connected serially to provide an extended continuous fixture.

The light engine comprises the light sources, an elongated lens, and any other optical elements that tailor the outgoing light to a particular profile. External reflectors are included to further shape the output beam. The reflectors may be shaped to define louvers which direct some of the emitted light in a direction opposite the primary emission direction, e.g., as uplight. The fixtures may be connected in a serial arrangement using a joiner.

Abstract: The fixture includes an elongated back reflector along the longitudinal direction of the fixture and at least one light source mounted to a heat sink structure and arranged to emit at least a portion of light toward the back reflector. The back reflector redirects at least a portion of the light toward an exit lens which interacts with the light as it is emitted from the fixture. Both the shape of the individual fixture elements (e.g., the back reflector and the exit lens) and the arrangement of these elements provide an asymmetrical light output distribution. Various mount mechanisms may be used to attach the fixture to a surface such as a ceiling or a wall, or the fixture may be suspended from a in a pendant configuration.

Abstract: A thermal ink jet ink composition include a volatile organic solvent, a binder resin, a dye, a humectant in an amount less than 40% by weight of the thermal ink jet ink composition, and an additive for extending the decap time. The additive is present in an amount greater than 0.1% by weight of the thermal ink jet ink composition. The additive is selected from plasticizers, surfactants, aliphatic hydrocarbons, drying oils and mixtures thereof. The additive does not phase separate from the ink jet composition during application of the ink to a substrate in thermal ink jet printing.

Abstract: A linear solid state lighting fixture with asymmetric distribution. The fixture comprises an elongated back reflector along the longitudinal direction of the fixture. At least one light source is arranged to emit toward the back reflector. The source(s) are mounted to a heat sink structure such that at least a portion of light emitted from the source(s) first impinges on the back reflector which redirects at least a portion of the light toward an exit lens. The exit lens interacts with the light as it is emitted from the fixture. Both the shape of the individual fixture elements (e.g., the back reflector and the exit lens) and the arrangement of these elements provide an asymmetrical light output distribution. Various mount mechanisms may be used to attach the fixture to a surface such as a ceiling or a wall, or the fixture may be suspended from a in a pendant configuration.
