We have disclosed a modular personal network (MPN) that includes multiple devices that may be worn, carried, or used in close proximity to a user. The devices communicate wirelessly. Functions of the MPN may be modified by adding or removing components. The MPN may communicate with a personal computer. General purpose devices may include a control unit, a display, a user input, and an audio output. The MPN may provide a variety of functions, including time, communication, entertainment, organization, guidance, athletic, medical, travel, outdoors, identity, security, and military.

Satellite radiotelephone systems include a space-based component that is configured to provide wireless radiotelephone communications in a satellite footprint over a satellite radiotelephone frequency band. The satellite footprint is divided into a plurality of satellite cells, in which satellite radiotelephone frequencies of the satellite radiotelephone frequency band are spatially reused. An ancillary terrestrial network is configured to terrestrially reuse at least one of the ancillary radiotelephone frequencies that is used in a satellite cell in the satellite footprint, outside the cell and in some embodiments separated therefrom by a spatial guardband.

In a multi-core processor, a high-speed interrupt-signal interconnect allows more than one of the processors to be interrupted at substantially the same time. For example, a global signal interconnect is coupled to each of the multiple processors, each processor being configured to selectively provide an interrupt signal, or pulse thereon. Preferably, each of the processor cores is capable of pulsing the global signal interconnect during every clock cycle to minimize delay between a triggering event and its respective interrupt signal. Each of the multiple processors also senses, or samples the global signal interconnect, preferably during the same cycle within which the pulse was provided, to determine the existence of an interrupt signal. Upon sensing an interrupt signal, each of the multiple processors responds to it substantially simultaneously. For example, an interrupt signal sampled by each of the multiple processors causes each processor to invoke a debug handler routine.

An interactive table has a display surface on which a physical object is disposed. A camera within the interactive table responds to infrared (IR) light reflected from the physical object enabling a location of the physical object on the display surface to be determined, so that the physical object appear part of a virtual environment displayed thereon. The physical object can be passive or active. An active object performs an active function, e.g., it can be self-propelled to move about on the display surface, or emit light or sound, or vibrate. The active object can be controlled by a user or the processor. The interactive table can project an image through a physical object on the display surface so the image appears part of the object. A virtual entity is preferably displayed at a position (and a size) to avoid visually interference with any physical object on the display surface.

The present invention provides systems and methods for improved data communication between communication terminals such as a base station and an unmanned aerial vehicle. In some instances, the systems and methods described herein provide robust transmission uplink data such as control data and wideband transmission of downlink data such as image data or other sensor data, while avoiding interference between the uplink data transmission and the downlink transmission.

A system and method are provided for managing communication with a plurality of wireless client devices operating in a radio frequency band shared by other types of devices, comprising a step of controlling at least one parameter associated with radio communication with each of the plurality of wireless devices based on the radio frequency environment associated with each corresponding one of the plurality of wireless client devices. Spectrum profile information describing the radio frequency environment (activity in the frequency band) at a wireless client device is sent to the wireless base station device (where the parameter controls are made) from either a wireless client device or another radio device in the proximity of one or more wireless client devices that is capable of generating the spectrum profile information. The spectrum profile information may include information identifying signals that are occurring in the frequency band in the proximity of a wireless client device. Examples of parameters that may be controlled at the wireless base station device include packet fragmentation threshold (the length of a data packet), transmission data rate and transmission scheduling (synchronizing a transmission to quiescent intervals of one or more periodic interfering signals).

Abstract of Disclosure A system and method for managing the spectrum utilization of a frequency band that is shared, both in frequency and time, by multiple devices. At one or more devices operating in the frequency band, pulses associated with signals occurring in the frequency band are detected by sampling part or all the frequency band for a time interval. From the detected signal pulses, the signals can be classified. In addition, overall spectrum activity can be measured. Using classification information for signals detected in the frequency band, policies can be executed so that a device may take certain actions in order to avoid interfering with other signals, or to optimize simultaneous use of the frequency band with the other signals. Signal detection occurs at one or more devices operating in a frequency band. Signal classification and measurement, as well as policy execution may occur within a processor of the same device where signal detection occurs, or in another device (located remotely or within the operating region of the frequency band).

The present invention provides a contract construction and execution methods and apparatuses. The contract construction method comprises: receiving a contract construction application submitted by a contract participant; generating a contract and a contract record according to the contract construction application, and sending the contract to a third-party mechanism of the contract participant; storing the contract signed by the contract participant and the third-party mechanism, and issuing information of the contract at a block chain; acquiring a pre-created state of the contract participant of the contract; when the state of the contract participant meets a trigger condition, creating a contract transaction record; and issuing the contract transaction record signed by a contract server and the third-party mechanism to the block chain and executing a contract transaction. By adopting the scheme provided by the present invention, the contract in the digital form is written into the block chain, and storage, reading and execution are guaranteed by the characteristic of the block chain technology, and the whole process is transparent and can not be tampered, so that interference of malicious behaviors towards normal execution of the contract can be avoided.
