Encoded information reading terminal with micro-electromechanical radio frequency front end

An encoded information reading (EIR) terminal can comprise a microprocessor electrically coupled to a system / data bus, a memory communicatively coupled to the microprocessor, an EIR device, a multi-band antenna, and a wireless communication interface. The EIR device can be provided by a bar code reading device, an RFID reading device, or a card reading device. The EIR device can be configured to output raw message data containing an encoded message and / or output decoded message data corresponding to an encoded message. The wireless communication interface can comprise a radio frequency (RF) front end electrically coupled to the multi-band antenna. The RF front end can comprise a micro-electromechanical (MEMS) filter array including one or more band-pass filter. Each band-pass filter of the MEMS filter array can be electrically coupled to a bias voltage source or an oscillating signal source. The RF front end can be electrically coupled to an analog-to-digital (A / D) converter and / or to a digital-to-analog (D / A) converter. The wireless communication interface can be configured to transmit radio signals in two or more frequency regulatory domains and / or receive radio signals in two or more frequency regulatory domains. The multi-band antenna can in one embodiment be provided by a meta-material antenna.

Multi-function field-deployable resource harnessing apparatus and methods of manufacture

A multi-function, field-deployable resource harnessing apparatus 600 having, in its embodiments, an inflatable reflector apparatus 610 comprising a least one manufactured parabolic mirror made from a pressure-deformable reflective covering of an inflatable ring for focusing electromagnetic energy from radio frequency radiation (RF) through the ultraviolet (UV) radiation including solar energy for (1) heating and cooking, (2) electrical power generation, (3) enhancing the transmission and reception of radio signals, (4) enhancing vision in low-light environments, and/or (5) projection of optical signals or images. The device also has non-electromagnetic uses, such as the collection and storage of water, harnessing of energy from a fluid stream, and/or harnessing wave energy. A first main embodiment of the inflatable reflector apparatus 610 generally utilizes two pressure-deformable membranes, at least one of which is reflective. A second main embodiment utilizes a reflective membrane and a transparent membrane. In addition to the reflector apparatus 610, the modular apparatus 600 typically further includes modular assemblies to increase versatility, facilitate use, and/or enhance safety such as, for example, a modular support and orienting assembly 612, a separate support ring 614, a safety shield or cage 616, a focal point support assembly 618, a safety cover 620, a safety net or mesh 622, and a stabilizing assembly 624. Portability is enhanced by complete collapsing of the inflatable device.

Handover between wireless telecommunication networks/systems

A method and a wireless telecommunication system of performing network-assisted handover of calls between a serving network and another wireless network that employs communication protocols different from those of the serving network. A message is sent from a mobile station of a user to the serving wireless network, which includes an indication that the mobile station is capable of communicating with the neighboring wireless network. Information relating to the communication characteristics of the neighboring wireless network is also sent from the serving wireless network to the mobile station. Using the information relating to the communication characteristics of the neighboring wireless network, the mobile station receives radio signals from the neighboring wireless network. The quality of the radio signals between the mobile station and the neighboring wireless network is measured. The serving wireless network sends a message to the neighboring wireless network to request a handover of the communication transaction when the quality of the radio signals between the neighboring wireless network and the mobile station meets a predetermined minimum threshold. Then a handover of the communication transaction from the serving wireless network to the neighboring wireless network is executed after the neighboring wireless network has established a communication channel for the mobile station pursuant to the handover request.

Land vehicle communications system and process for providing information and coordinating vehicle activities

A communication system architecture (SA) for a vehicle which may be integrated into the vehicle's multiplexed electronic component communication system, and a process for communicating with the vehicle to provide information for and about the vehicle's operational status and coordinating the vehicle's activities. The communication system will include a multi-functional antenna system for the vehicle that will have the capability to receive AM/FM radio and television signals, and transmit and receive citizens band (CB) radio signals, satellite and microwave and cellular phone communications. The antenna may be installed as original equipment or as a back-fit part in the after-market. In either case the multi-functional antenna will be integrated with the vehicle's multiplexed electronic component communication system. The process for communicating with the vehicle will involve a communication service for which the vehicle's driver will enroll for and service will continue so long as maintenance fees are paid. The service will be capable of providing various levels of information transfer and coordination. The levels may include vehicle information such as (1) the need for servicing and location of the nearest service center with the necessary parts in stock, (2) routing, and (3) load brokering and coordination. The modular design of the system architecture (SA) will allow it to be employed with the vehicle platform that does not possess a full multiplexed electronic component communications system. The resulting vehicle, using an after-market application package, will be able to participate in some of the services.
