Abstract:
A battery-powered motorized window treatment (310) for covering at least a portion of a window may be adjusted into a service position to allow for access to at least one battery (138) that is powering the motorized window treatment (310). A headrail of the motorized window treatment may be adjusted to the service position to allow for easy replacement of the batteries (138) without unmounting the headrail8114) and without requiring tools. The motorized window treatment (310) may comprise brackets (370) having buttons (372) that may be actuated to release the headrail (114) from a locked position, such that the headrail (114) may be rotated into the service position. The headrail (114) easily rotates through a controlled movement into the service position, such that a user only needs one free hand available to move the motorized window treatment (310) into the service position and change the batteries (138).

Abstract:
Techniques to control a shared antenna architecture (150) for multiple co-located radio modules is disclosed. For example, a method may comprise receiving power state information for a set of transceivers (114, 118), receiving activity information for the set of transceivers (114, 118), and generating control signals for simultaneous operations or mutually-exclusive operations for a shared antenna structure (150) connecting the set of transceivers (114, 118) to an antenna (110) based on the power state information and activity information. Other embodiments are disclosed and claimed.
Abstract:
A method is provided a wireless system for providing small "guard" cells in a heterogeneous network at locations proximate to privately-maintained HeNB (or femto) cells in the heterogeneous network. More particularly, the methodology of the invention addresses the problem of a mobile user in a heterogeneous network located nearby to a privately maintained HeNB cell in the heterogeneous network, and the inherent interference created for the HeNB cell by the necessity of the mobile user having to transmit and receive communications from a distant public macro eNB. By deploying small public "guard" cells in the macro cell proximate to the private HeNB cells, such a public mobile terminal is enabled to communicate with the public small cell at generally lower power than would have been necessary for communication with the distant macro eNB, with a resulting reduction in interference for the nearby HeNB cell. The FL interference between the macro cell and the HeNBs is also mitigated.
Abstract:
A local device broadcasts a service advertisement in a wireless network, where the service advertisement includes one or more service identifiers (IDs) identifying one or more services being advertised and an availability schedule of the local device. Optionally, the local device reduces power to at least a portion of the local device and wakes up at a time according to the availability schedule. The local device listens in the wireless network according to the availability schedule of the local device. In response to a service request received from a remote device during the availability window, the local device transmits a service response to the remote device. The service request includes one or more service IDs identifying one or more services being inquired by the remote device and the service response includes detailed information associated with one or more services identified by the one or more service IDs.
Abstract:
The present disclosure provides an arrangement for wireless network availability enhancement. According to an embodiment of the present disclosure, an arrangement for wireless network availability enhancement comprises alternate power sources, a base transceiver station and a base station controller. Further, the information of following parameters is monitored regularly and communicated to the remotely located Base Station Controller: charging current (I-charging) from the power source, drain current (I-drain) towards the Base Transceiver Station and the battery bank charge level (BB-cLevel). After receiving the charge and power status information from the BTS site, BSC propagates the control signals for graceful reduction of network capacity, instead of making the services fully unavailable. It also propagates the control signals for gradual enhancement of the network capacity.
Abstract:
An apparatus comprises a sequence generator configured to generate a reference sequence for scrambling scattered pilots, edge pilots and/or frame closing pilots in data symbols, such as Orthogonal Frequency Division Multiplexing (OFDM) symbols in a data stream. The sequence is based, at least in part, on a symbol number of the data symbol in which the pilots are to be included. A receiving apparatus may then identify a symbol having a particular symbol number in a received data stream based on the scrambling sequence. Where the data stream carries multiple services in bursts or time slices, the receiving apparatus may remain in sleep mode between the bursts associated with a desired service. The method permits a receiver that has "woken up" to identify a received symbol having a particular symbol number and synchronize its symbol index.
Abstract:
Methods and apparatus are directed to mobile devices utilizing motion and/or position sensors for improving operating performance and/or power efficiency. In one example, a method for reducing power consumption in a mobile device includes receiving movement information, establishing movement data based on the movement information, determining if the mobile device is stationary using the movement data; and reducing the frequency of searching for a base station when the mobile device is stationary. In another example, a mobile device which reduces power consumption based upon movement data includes an RF front end, a receiver coupled to the RF front end, a data demodulator coupled to the receiver, a searcher, coupled to the RF front end and the receiver, which searches for base stations, and a processing unit coupled to the searcher, wherein the processing unit controls the searcher based upon the stationarity of the mobile device.
