Thin film precursor stack for mems manufacturing

Abstract: This invention provides a precursor film stack for use in the production of MEMS devices. The precursor film stack comprises a carrier substrate, a first layer formed on the carrier substrate, a second layer of an insulator material formed on the first layer, and a third layer of a sacrificial material formed on the second layer.

Method and apparatus for measuring channel state information

Abstract: A method and apparatus for transmitting in a multi-antenna communication system (100). Each of a plurality of antennas (116,122) are assigned with a different one of a plurality of groups of sub-bands. The plurality of groups of sub-bands each include a different sub-set of the plurality of sub-bands, where the plurality of sub-bands of a first group are non-contiguous. Transmitting from the plurality of antennas (116) and simultaneously using the plurality of groups of sub-bands, where transmitting from each antenna (116) occurs on the group of sub-bands assigned to the antenna (116). A base station for use in the multi-antenna communication system (100) including a first processor (332) for pre-conditioning transmission data, assigning a plurality of pilot symbols to the plurality of transmit antennas (116), and assigning a plurality of sub-channel sub-sets to the plurality of antennas (116). The plurality of antennas (116) transmit each of the assigned plurality of pilot symbols over their respectiven assigned sub-channel sub-sets.

System and method for managing payment in transactions with a pcd

Abstract: A system and method for managing payment in a transaction using a portable computing device (“PCD”) includes a mobile wallet token being received from an account issuing entity Next, the mobile wallet token is stored in memory within a PCD payment platform (ie, a cloud payment solution) A PCD token that corresponds with the mobile wallet token is generated by the PCD payment platform The PCD token is transmitted over a communications network to a PCD The mobile wallet token corresponds to at least one of: a credit card account, an alternative or non-traditional payment account, a stored value account, an account from a financial institution, and a merchant based card account A mobile wallet token may be generated in response to receiving input from an on-line portal that future use of a payment account with a PCD is desired or in response to input received from a point-of-sale terminal

Methods, devices and systems for self charging sensors

Abstract: Methods, systems and devices for an energy harvesting sensor are disclosed. A sensor device may include an energy harvesting element configured to harvest energy from a source of energy that is to be measured by the sensor device, and an energy storage element configured to store energy generated by the energy harvesting element. The sensor device may further include a transmitter circuit coupled to the energy storage element and configured to transmit a wireless signal when the energy stored in the energy storage element is sufficient to power a transmission of the wireless signal. The time between transmissions by the transmitter may be used by a receiver of those transmissions to calculate a measure of the quantity being used for energy harvesting.
