摘要:
This invention provides a cost-effective means for both indoor and greenhouse farmers to use a Modular Light Emitting Diode (LED) Grow Light System to optimize light distribution and integrate natural light. The Modular LED Grow Light System consists primarily of multiple narrow “Linear Modules” connected to two “End Housings” with structure from “Support Braces” that together form each “Grow Rack” within the system. The Linear Modules are longer than their diameter, and the spacing between the Linear Modules is greater than their diameter. This creates spaces between each Linear Module with three primary advantages: more even light distribution, more integration of natural light, and more air flow for natural ventilation.

An LED replacement light for a fluorescent lighting fixture. The replacement light assembly includes a metal housing for heat dissipation and structural support. A standard plug for mating with the original lighting fixture connector is provided to allow direct replacement of an existing fluorescent light bulb. A control circuit having a power supply, a current controller, and a current sensor converts the fluorescent lamp power supply output to an output sufficient to drive the LEDs. The current controller generates a variable pulse width waveform for powering the LEDs, and a current sensor circuit regulates the flow of current through the LEDs. High-brightness LEDs are utilized and are spaced sufficiently apart to provide fewer point-sources of light while retaining overall equivalent luminance. A glare shield controls the light pattern emanating from the LEDs to direct the pattern illumination.

A disk storage system includes a substantially planar disk case, configured to removably receive a substantially flat disk. The case includes a locking bar disposed along an edge of the case, the locking bar being configured to releasably pivotally press fit into receiving structure of a disk storage container.

Described are methods and apparatus, including computer program products, for defining logical trunk groups in a packet-based network. A plurality of logical trunk groups are defined for a first media gateway in communication with a packet-based network. Each of the plurality of logical trunk groups is associated with one or more media gateways in communication over the packet-based network with the first media gateway. Data associated with a call that is received or transmitted by the media gateway is associated with a first logical trunk group of the plurality of logical trunk groups.

Methods, systems, and computer readable media for stress testing mobile network equipment using CPRI are disclosed. According to one method, a plurality of messages is generated for simulating a plurality of user equipment (UE) devices. The plurality of messages is transmitted over a common public radio interface (CPRI) link to a radio equipment controller (REC) in order to stress test the REC component.

摘要:
A bottle and cup holder for retaining a bottle or cup, having a skin cover forming an outermost layer of the holder; a foam insert within the skin cover having a central cavity and an opening. The central cavity has a first section, a second section, and a shoulder. The second section is between the first section and the opening. The shoulder is between the first section and the second section. The second section has a larger diameter than the first section. The bottle and cup holder also has a shoulder bushing within the opening and extending into the central cavity to receive the bottle or cup.
