Portion of a luminaire

Light bar for a luminaire

Systems and methods for collapsible lighting fixtures are disclosed. In aspects, a horticultural luminairehas first and second light fixturescoupled in movable relation between storage and deployed positions by a coupling elementapplying a retarding torque. Coupling element can be coupling shaftproviding friction, or friction hinge cartridge. In aspects, hingehas ledge surfacesadjacent rotational hinge facesand extending transverse the rotational plane. In aspects, a horticultural luminaire has an articulated cableway extending through hingecoupling light fixturesand guiding a cable entering from the exterior into cable passageways in light fixtures, thereby lessening a cable pinch point during rotation and deployment.

Luminaire having a cableway

In one embodiment, a printed circuit board assembly comprises a heat sink having an electrically conductive mounting support and a printed circuit board including detection circuitry to detect an electrical connection between the electrically conductive mounting support and an electrically conductive receiver on the printed circuit board.

Heat sink detection

A slot in a media drive cage receives a protrusion of a media drive housing. A spring adjacent to the slot engages the protrusion just before it reaches the end of the slot, causing the media drive to slow down prior to reaching a fully engaged position within the cage. The frictional slowing reduces mechanical shock to the drive when its movement stops. A resilient finger at the end of the slot further reduces shock. A resilient latch retains the drive within the slot. To remove the drive, the latch may be disengaged by pulling on a hook portion of the latch. The slot may be nonlinear to enable airflow through the slot and over the drive, thus facilitating cooling of the drive.

Media drive cage having improved insertion shock and air flow properties

In one embodiment, a fastener includes an integrated isolation member composed of a resilient material, the isolation member being adapted to isolate a storage media drive to which the fastener is to be mounted from a drive cage in which the drive is to be installed, the isolation member being sized and configured to fit within a slot of the drive cage and to abut a surface of the drive cage.

Storage media drive isolation apparatus and methods

A computer system having electronic components housed in a central unit having a protective enclosure and a cover. The cover is moveable to provide access to electronic components housed in the central unit. The cover allows access to certain electronic components and prevents access to other electronic components.

Computer system and chassis

Tower personal computer

A computer which includes modular structures incorporated therein provides enhanced serviceability. In a preferred embodiment, the computer has a chassis, a lid, a front bezel, an option card module, a system board module, a drive module, and a power supply module. The lid secures the option card module within the chassis. The option card module is removable from the chassis without disconnecting fasteners, option boards, or external cables therefrom. The system board module is received in the chassis and is secured therein by the option card module. The drive module has features which enable storage media devices to be conveniently installed therein and removed therefrom.

Modular desktop computer having enhanced serviceability

Modular computer apparatus

The present invention supports computers or electronic devices that have a sleep, hibernation or low power mode. Because a device may appear to be off in low power mode, the present invention acts as an interlock to prevent or deter access to the device's electronics unless the power to the device has been disconnected or turned off.
