Filed:

Aug 27, 2007

Appl. No.:

11/845640

Inventors:

Carl T. Gould - Boulder CO, US
Gary D. Trott - Eatonton GA, US
Christopher L. Sharp - Conyers GA, US

Assignee:

ABL IP Holding LLC - Conyers GA

International Classification:

F21S 4/00

US Classification:

362223, 362337, 362339

Abstract:

A light fixture or troffer for directing light emitted from a light source toward an area to be illuminated, including a reflector assembly within which the light source is positioned and a lens assembly detachably secured to a portion of the reflector assembly such that a lens of the lens assembly overlies the light source and such that substantially all of the light emitted from the light source passes through the lens assembly. In one example, the lens includes a curved prismatic surface that can be oriented toward or away from the underlying light source.

Assignee:

Acuity Brands, Inc. - Atlanta GA

International Classification:

F21S 4/00

US Classification:

362220, 362221, 362364

Abstract:

A replacement light fixture for directing light emitted from a light source toward an area to be illuminated, including a base member upon with the light source is positioned and a reflector assembly detachably secured to a first and second mounting brackets that are mounted to a portion of the preexisting light fixture housing such that a lens portion of the reflector assembly overlies the light source and such that substantially all of the light emitted from the light source passes through the lens portion.

International Classification:

F01N 3/00

US Classification:

60286, 60274, 60284, 60295, 60301, 60285

Abstract:

An emissions control system is disclosed. The emissions control system may have a power source that creates a flow of exhaust and a filtering device that receives the flow of exhaust. A first sensor may be located at or upstream of the filtering device, the first sensor being configured to measure a first temperature, and an SCR catalyst may be located downstream of the filtering device. The emissions control system may also have an injector configured to inject a reduction agent into the flow of exhaust in the presence of the SCR catalyst. The emissions control system may further have a controller in communication with the first sensor. The controller may be configured to predict a change in an ability of the SCR catalyst to store reduction agent using a measured change in the first temperature and adjust the injector according to the predicted change in the storage ability of the SCR catalyst.

International Classification:

F01N 3/00
F01N 3/10

US Classification:

60286, 60295, 60299, 60301, 60303

Abstract:

An emissions control system is disclosed. The emissions control system may have a power source that creates a flow of exhaust, an SCR catalyst situated to receive the flow of exhaust, and an injector configured to inject a reduction agent into the flow of exhaust in the presence of the SCR catalyst. The emissions control system may further have a controller configured to calculate a spatially dependent surface coverage of the reduction agent on the SCR catalyst and substantially stop injection of the reduction agent when the spatially dependent surface coverage of the reduction agent exceeds a maximum surface coverage of the reduction agent at one or more spatial locations.

Abstract:

Methods and apparatus for large scale distribution of electronic access control clients. In one aspect, a tiered security software protocol is disclosed. In one exemplary embodiment, a server electronic Universal Integrated Circuit Card (eUICC) and client eUICC software comprise a so-called “stack” of software layers. Each software layer is responsible for a set of hierarchical functions which are negotiated with its corresponding peer software layer. The tiered security software protocol is configured for large scale distribution of electronic Subscriber Identity Modules (eSIMs).
