At least one server is queried to obtain program data. DVR data is obtained from a digital video recorder, substantially in real time, over a content-based network. The program data and/or the DVR data are displayed on a separate remote device, in communication with the content-based network. A request to record a given program on the at least one digital video recorder is received at the separate remote device. A conflict associated with the request to record the given program is detected, and the conflict is resolved based at least on a user input received at the separate remote device.

A cover for a device is disclosed. The cover may include a first portion operable to protect a button of a device from inadvertent actuation, wherein the first portion enables viewing of the button while the cover overlaps the device. The cover may also include an opening operable to afford access to an interface component of the device, wherein the opening is operable to enable a user to reach through and physically interact with the interface component while the cover overlaps the device. The cover may further include a second portion enclosing the opening on all sides.

A subscriber access control system (SACS) configures a network device connected to cable network to affect the behavior of that device. The SACS comprises a rules engine and a datastore that stores the current state of subscribers known to the SACS and historical request information. When the SACS receives a request to quarantine a device, it assigns attributes to a subscriber record accessed by a DHCP server to affect the configuration and behavior of that device. The actual behavior of the quarantined device is determined by the presence of the attribute and the value of the attribute.

A horn loudspeaker comprises: a horn (22) having a throat (26) and a mouth (30); a primary electro-acoustic driver (24) mounted at or adjacent the throat of the horn and directed generally along the horn; and at least one secondary electro-acoustic driver (32T, 32B, 32L, 32R) mounted part-way along the horn and directed generally across the horn. The secondary driver(s) can be used to change the local impedance conditions in the horn and therefore to change the polar response of the horn loudspeaker. At least one filter (12A, 12E) is provided for filtering an input signal (34) for the primary driver to produce a filtered signal for the primary driver or each of the secondary drivers. Such a filter may be chosen or designed so as to optimize some aspect of the polar response of the horn loudspeaker, for example to increase directivity, or flatten the polar response within a specified included radiation angle, or to increase omnidirectionality.

A building curtain wall panel system is disclosed in which a plurality of mechanically fastened and bonded layers are provided to create a fire resistant, light weight and insulated panel which is easily installed and yet resists impact stress. The panel includes bonded layers attached to a steel frame. The strength and fire resistant properties are enhanced by a medium density calcium silicate composite panel. The exterior architectural design features may be varied by composite coatings including a variety of materials including acrylic resins, fibers, vicron, fungicide, coloring agents, cement and water.

Path calculation systems and methods for determining a path, based on constraints and rules, for a connection at one or more layers in a network, include determining a path exploration map of the network based on a multi-layer network model of the network defining external edges and intra-node paths, the path exploration map comprising every external port in the network that is reachable from a source port; and utilizing the path exploration map to determine a viable path, from a destination port to the source port, subject to the constraints and the rules and based on a cost.
摘要:
A communication device for communicating with a plurality of terminals via a wireless network, the communication device being configured to, when it has a message to transmit to that plurality of terminals: select, from a multiple of available acknowledgement mechanisms, an acknowledgement mechanism for the terminals to use in acknowledging receipt of the message and communicate the selected acknowledgement mechanism to the plurality of terminals.
摘要:
A method for allocating communication resources in a network comprising a plurality of terminals, some of the terminals being mobile and others of the terminals being static, the method comprising designating one or more of the terminals as static terminals and allocating communication resources of the network in dependence on those designations.
