Abstract: A system for providing data to electrical devices in an interconnected network can include a user system disposed in a volume of space, where the user system has a communication range, where the user system broadcasts multiple communication signals into the volume of space. The system can also include an electrical device disposed within the communication range of the user system, where the electrical device includes a controller, where the controller can retrieve first information from a first communication signal, where the information includes a file identification for a file and a number of blocks in the file. The controller can also generate a table for the number of blocks in the file and retrieve second information from a second communication signal, where the second information comprises a first block of the file. The controller can also store the first block of the file in the table.

Abstract: An electrical device can include at least one electrical device component and at least one sensor that measures at least one parameter. The electrical device can also include an integrated control interface disposed on a housing of the electrical device and coupled to the at least one electrical device component, where the integrated control interface allows for manual control of the at least one electrical device component. The electrical device can further include an access controller communicably coupled to the at least one electrical device component and the at least one sensor. The access controller can receive, from the at least one sensor, a communication sent by a user. The access controller can also control, based on determining that the user has the authority to control the at least one electrical device component, the at least one electrical device component based on instructions.

Abstract: A lighting fixture for use in an automated store checkout system includes a light source, a camera, and a control unit. The control unit is configured to determine identifying attributes of a person from one or more images of the person captured by the camera. The control unit is further configured to transmit the identifying attributes to a controller and to provide a notification to the person via the light source based on a command received from the controller. The command is generated based on the identifying attributes.

Abstract: A control device can include a user interface configured to receive first user credentials from a first user and an electrical device controller configured to control at least one electrical device. The control device can further include an access controller communicably coupled to the electrical device controller and the user interface. The access controller can receive the first user credentials from the user interface, and also determine, based on the first user credentials, whether the first user has a first authority to control the at least one electrical device. The access controller can also send, based on determining that the first user has the first authority to control the at least one electrical device, the first authority of the first user to the electrical device controller, where the electrical device controller allows the first user to control the at least one electrical device according to the first authority.

Abstract: A system can include multiple electrical devices that includes at least one sensor that measures a first parameter. The system can further include a controller communicably coupled to the electrical devices and the at least one sensor. The controller can receive a first measurement of a first parameter from at least one sensor, where the first measurement is associated with a first electrical device of the electrical devices; determine, based on the first measurement, that the first parameter falls outside a first range of acceptable values caused by a failure of the first electrical device; determine that adjusting at least one other electrical device compensates for the failure of the first electrical device; and adjust the at least one other electrical device from a default setting to a compensatory setting to compensate for the failure of the first electrical device.

Abstract: Operating software commitment may be provided. First, a subscriber device may be configured using a factory software and a service provider software may be downloaded. Next, it may be verified that the subscriber device is properly configured. In response to verifying that the subscriber device is properly configured, the service provider software may then be committed to the subscriber device.

Abstract: The present invention provides methods for navigation in data sets that can contain non-uniform fields. In one embodiment, data sets are defined by horizontal and vertical axes, and horizontal and vertical bias lines are calculated to determine which field is highlighted in response to vertical or horizontal navigation of the data set. In response to a user's navigation, at least one bias line is recalculated. Additional axes, for example a z-axis, and corresponding additional bias lines can be implemented. The invention can be practiced as an interactive program guide for a subscription television service. The fields of the program guide may not be uniform because programs listed in the program guide may have variable start times and/or durations, or because channel information may be redundant. The invention provides more predictable navigation within an interactive program guide. By reversing navigation movements, a user returns to a previously highlighted field.
