A network controller is configured to receive a data packet from a core network for routing to a device in a wireless network. The controller may then select an antenna set from a plurality of antenna sets that are distributed across different base stations operable to transmit data packets to the destination device. The antenna set may be selected from the plurality of antenna sets based on a distribution pattern. For example, the distribution pattern may be a pseudo-randomly generated distribution pattern. The controller may then route the at least one data packet to the base station which the selected antenna set is implemented for transmission to the device. The antenna sets may be implemented on one base station, or implemented so that the antennas of an antenna set are distributed across multiple base stations. The antenna sets may also be configured to be of any number of antennas.

Spatial hopping using antenna sets across multiple base stations

Systems for utilizing bandwidth of a wireless network in an efficient manner are disclosed. Bandwidth may be allocated between different types of devices by dividing a symbol constellation into subsets of points, where each of the subsets may be used for transmitting data from a different device to a base station on single frequency channel. The symbol constellation may be shared on the frequency channel by dynamic or static allocation of the subsets of points to different devices. A first device with high data speed requirements may be allocated a first subset of points of the symbol constellation fix transmitting data to the receiver, while a second device with lower data speed requirements may be allocated a second smaller subset of the symbol constellation for transmitting data to a receiver. The first and second devices may then transmit data to the receiver on the frequency channel.

Signal design for diverse data rates

A method for generating a spreading sequence is disclosed. The method includes receiving a plurality of signals from a remote device. The plurality of signals is sampled to generate a plurality of data sets corresponding to the plurality of signals, respectively. Each data set indicates a power value of the corresponding signal. From the plurality of data sets, one or more data sets indicating a power value greater than a predetermined value is selected. A spreading sequence is generated based on the one or more selected data sets.

Sequence generation for spread spectrum from signal sampling

Devices, systems, and methods for locking a hybrid electronic device are described herein. An electronic device may include a housing, a first lock component attached to the housing or positioned in an opening of the housing, and a second lock component attached to the housing or positioned in an opening of the housing. The electronic device may be configured to connect with a locking device at the first lock component. The electronic device may also be configured to connect with an additional electronic device at the second lock component to provide a hybrid electronic device. Additionally, when the locking device is connected at the first lock component, the electronic device is configured to prevent the additional electronic device from being detached at the second lock component.

Locking mechanisms in hybrid electronic devices

A method for generating spread spectrum spreading sequences in communicating devices. A first device receives a first sequence of one or more signals from a second device, sends a second sequence of one or more signals to the second device, samples the first sequence of one or more signals, generates sampling results, and generates a spreading sequence based on the sampling results. The second device receives the second sequence and creates an identical spreading sequence using an identical process to create sampling results and generate the sequence. The spreading sequence may be used by the first and second devices for spread spectrum communications with each other. Gain for spread spectrum communications may be dynamically varied based on available bandwidth by varying the number of signals and sampling rate.

A dual-mode includes a light source configured to project a structured illumination from which visible light can be filtered. The dual-mode imager also includes a detector configured to capture both the structured illumination and visible light from the scene. A temporal or spatial filter is used to selectively block visible light from one or more portions of the detector while passing the structured illumination to the one or more portions of the detector.

Imager for constructing color and depth images

Techniques for locating wireless channels usable for transmitting media signals from personal media players that are adequately separated from wireless channels used for other purposes. One technique involves identifying a target channel and at least two additional channels within a certain proximity of the target channel, and evaluating a channel usability algorithm based on characteristics, such as the received signal strengths, of the target channel and the received signal strengths of each of the proximate channels. Based on evaluation of the algorithm, the target channel is deemed either usable or not usable to transmit the media signal. The most desirable available target channel(s) in a particular group or sub-group of wireless channels may also be identified.
