Abstract: The present invention provides a current blocking structure for electronic devices, preferably optoelectronic devices. The current blocking structure comprises a semiconductor material arrangement comprising an n-type ruthenium doped indium phosphide (Ru—InP) layer and a first p-type semiconductor material layer wherein the n-type Ru—InP layer is less than 0.6 ?m thick. The semiconductor material arrangement and p-type semiconductor material layer form a current blocking p-n junction. The current blocking structure may further comprise other n-type layers and/or multiple n-type Ru—InP layers and/or intrinsic/undoped layers wherein the n-type Ru—InP layers may be thicker than 0.6 ?m.

Abstract: An arrangement for use in a utility meter includes a non-volatile memory and an RF transceiver. The non-volatile memory has a first and a second port, the first port configured to obtain commodity consumption data. The radio frequency (RF) transceiver is configured to receive an RF signal from an external source and obtain energy from the RF signal and provide the energy to a bias voltage input of the non-volatile memory. The RF transceiver is further operable to perform a data transfer operation responsive to the received RF signal, the data transfer operation including a transfer of meter-related data between the non-volatile memory and the RF transceiver using the second port of the non-volatile memory.

Abstract: A utility meter implementing the ANSI C12.19 standard is able to bypass security processing using Decade4 security tables for a single data access operation. The meter includes a procedure that is executed by a processor in the meter to process requests for security keys. Data internal to the meter is used to generate a security key. The security key is used by the requesting external device and the procedure to generate an access key. The external device sends its access key to the procedure so it may be compared to the internally generated access key. If both access keys are the same, a data access operation performed by the external device is allowed without reference to the Decade4 security tables. Once a timeout or data access operation is performed, subsequent data access operations are subject to processing in accordance with the Decade4 security tables unless another security key is requested for repetition of the process.

Abstract: Wines and other alcoholic beverages are treated to remove sulfides by passing the beverage through a filter medium comprising polyvinyl polypyrrolidone, polyvinylimidazole, or a copolymer of the monomers of these two polymers, the polymer or copolymer having been pretreated with a solution of a metallic salt, preferably copper sulfate or silver nitrate.
