Abstract: A system is disclosed for a digital rights management system which enforces license rights by establishing an account domain of registered consumer devices which may each receive a decryption key to be used to decode digital content bought by any of the devices within the account domain. Such system further enables the decentralization of content sharing by establishing a network of trusted intermediate devices to manage licenses on end devices for a central rights provider.

Abstract: An apparatus for mounting a power tool to a vice, e.g. a vice-cum-workbench such as a Black and Decker™ Workmate™, is disclosed. The apparatus includes a support that may be releasably attached to or an integral part of the power tool. The support comprises one or more projections that when the tool is placed on top of the vice depend down for retainment by the vice's jaws, thereby rigidly supporting the power tool to the vice. The projections are retractable, e.g. through a pivoting action, in order that they do not destabilize the tool when it's supported on a surface other than a vice. The projections may be arranged to retract under the weight of the tool upon it.

Abstract: Methods and apparatus for retaining a fastener receiver are disclosed. An example apparatus includes a retainer to retain a nut assembly adjacent an object. The retainer includes a first plate defining a first opening. The first plate is to couple to the object. The first opening is to receive a portion of the nut assembly when the retainer is coupled to the object. The retainer includes a second plate defining a second opening and including a first deflectable tab adjacent the second opening. The second plate is to couple to the first plate opposite the object. The deflectable tab of the second plate is to cover a portion of the first opening of the first plate. The first deflectable tab is to deflect to receive and retain the portion of the nut assembly in the first opening when the retainer is coupled to the object.

Abstract: The invention provides systems and methods for provisioning a site with an energy system such as a solar energy system. A system according to an embodiment of the invention comprises a user interface module providing a graphical user interface for receiving information from a user, for example a potential purchaser. The information includes location information for the site to be provisioned. An image retrieval module is coupled to the user interface module and to a source of geographical information. The image retrieval module retrieves at least one image of the site corresponding to the location provided by the user. A sizing module is configured to enable a user to measure an installation surface represented in the image. Energy system components are selected based on the measurements.

Abstract: The invention provides consumers, private enterprises, government agencies, contractors and third party vendors with tools and resources for gathering site specific information related to purchase and installation of energy systems. A system according to one embodiment of the invention remotely determines the measurements of a roof. An exemplary system comprises a computer including an input means, a display means and a working memory. An aerial image file database contains a plurality of aerial images of roofs of buildings in a selected region. A roof estimating software program receives location information of a building in the selected region and then presents the aerial image files showing roof sections of building located at the location information. Some embodiments of the system include a sizing tool for determining the size, geometry, and pitch of the roof sections of a building being displayed.
