International Classification:

H04Q 700

US Classification:

370329, 370342

Abstract:

A source device ( ) stores predetermined data and establishes a channel selection profile comprising a plurality of channel selections. Each channel selection is derived from a subset of the predetermined data. The source device ( ) transmits at least a portion of the predetermined data over at least a first channel selected from the channel selection profile.

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

G08B 13/14

US Classification:

3405721, 3405727

Abstract:

The present invention provides a multi-band, multi-mode RFID tag that uses a single antenna structure and integrated circuit to provide asset location information at any stage of a supply chain. The unified tag design operates at multiple frequencies (or bands) using the antenna structure, for example, 125 kHz, 13. 56 MHz, 915 MHz, and 2. 45 GHz, and preferably operates electrostatically (at lower frequencies) and electromagnetically (ay higher frequencies). An on-chip frequency monitor in the integrated circuit automatically determines which frequency is present and derives a local clock for the tag's integrated circuit, which can vary in accordance with the frequency or which can be constant. Alternatively, a phase locked loop circuit can be used to derive a local clock signal modulated into the interrogation signal. On-chip matching and power extraction circuits derive power for the tag from the interrogation signal, which is preferably passive.

US Classification:

455229, 455522, 3405721, 340 101, 340 592, 340 561

Abstract:

A source device () receives a carrier signal and continuously monitors the carrier signal for a first predetermined condition and a second predetermined condition. The source device () transmits data if the first predetermined condition is satisfied. The source device () ceases transmission of data if the first predetermined condition subsequently is not satisfied or if a second predetermined condition is satisfied.

Assignee:

Motorola Solutions, Inc. - Schaumburg IL

International Classification:

H04J 3/16

US Classification:

370252, 370329

Abstract:

A radio communication system () provides a radio air interface at a master node () for subscriber units associated with the master node. Among the subscriber units are several slave nodes (). The communication system has the ability to operate as a secondary user in unused spectrum portions of a frequency band otherwise reserved for primary operators, such as licensed broadcasters. The master node accesses an authorization server () to obtain a list of unused channels in the region of the master node. Each slave node also contacts the authorization server to obtain a list of unused channels in the region where each respective slave node is located, via another network (). The unused channels common to the slave nodes and the master node are used to create a backup radio operating parameter list which is used by the master node if a fault occurs between the master node the authorization server.

International Classification:

H01L029/74

US Classification:

257/140000

Abstract:

High quality epitaxial layers of monocrystalline materials can be grown overlying monocrystalline substrates such as large silicon wafers by forming a compliant substrate for growing the monocrystalline layers. An accommodating buffer layer comprises a layer of monocrystalline oxide spaced apart from a silicon wafer by an amorphous interface layer of silicon oxide. The amorphous interface layer dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer. The accommodating buffer layer is lattice matched to both the underlying silicon wafer and the overlying monocrystalline material layer. Any lattice mismatch between the accommodating buffer layer and the underlying silicon substrate is taken care of by the amorphous interface layer. In addition, formation of a compliant substrate may include utilizing surfactant enhanced epitaxy, epitaxial growth of single crystal silicon onto single crystal oxide, and epitaxial growth of Zintl phase materials. Furthermore, a pre-computation unit is implemented in the compound semiconductor material to pre-compute instructions directly in the memory system, thereby resulting in substantially increased processing throughput.
