A method and apparatus to dynamically control selectable vocoder rates in a CDMA network to optimally improve forward and reverse link capacity as necessary. To improve capacity, a number of vocoder rates are used, each requiring a different average data rate and providing a different level of voice quality. Vocoder rates are reduced to lower sector average output power thereby improving forward and reverse link capacity. Forward and reverse link loading are compared to established thresholds that, if exceeded, would trigger a forward link and a reverse link vocoder rate adjustment as necessary to improve network capacity. The forward link vocoder rate and reverse link vocoder rate may be set independently or the reverse link vocoder rate may be set as a function of the forward link vocoder rate to maintain a link balance.

A magnetic blade retainer for an expandable broadhead utilizing the properties of magnetic attraction to reliably secure a plurality of blades completely within respective blade channels so that an expandable broadhead may closely resemble the flight properties of a practice arrow tip yet lethally expand upon impact with a target. Extraneous parts are eliminated, but a strong, disc magnet is inset or integrated into the forward portion of a broadhead tip assembly. Each blade is provided with a magnetic, flat forward end. The interaction of the flat forward end and the magnet magnetically retain each blade. The magnetic bond is broken when the arrow penetrates a target. An actuating spike further transfers the impact energy to each blade. The forces on the actuating spike then drag each blade backward and each blade extends as the rearward forces are translated by the wedging surface near the end of the channel.

The VEA Detector and Dynamic Range Controller of the invention more accurately measure constant or non-constant, periodic or aperiodic, signals and the use of such measurements to control the upstream and / or downstream processing of program signals, including without limitation audio, video, and power program signals. The invention uses an antilog module acting within the context of a log domain circuit such that the “averaging” at an integrator is linear, not logarithmic. However, since the detection is within the log domain, the dynamic range of the VEA Detector is exponentially larger.

The invention is an apparatus and method to allow a microcontroller unit with fewer pins to use SDRAM. This invention uses the SDRAM burst mode in a favorable way. On an initial cycle of the burst access the microcontroller supplies an address one less than the actual initial address on a multiplexed address / data bus connected to both the address bus and the data bus of the SDRAM. DQM signals from the microcontroller to the SDRAM suppress all data writes. On the second and subsequent cycles of the burst assess, the microcontroller supplies the next data word to be written on the multiplexed address / data bus together with DQM signals permitting data writing. This technique prevents collisions of address and data on the microcontroller multiplexed address / data bus.

An engine arrangement including an internal combustion engine and an energy recovering system includes an exhaust line collecting exhaust gas from the engine,a filter having an active portion inserted between two successive parts of the exhaust line, in order to hold the particles contained in the exhaust gas, and filter rotating means designed to rotate the filter so as to shift the active portion of the filter,a secondary line carrying intake air towards an area of said filter distinct from the active portion, according to a direction opposite from an exhaust gas flowing direction inside the filter, so as to sweep the particles away from the filter and release them downstream, inside the secondary line. The secondary line includes a first arrangement, located downstream from the filter, for burning the particles and thereby heating air flowing in the secondary line, and a second arrangement capable of recovering the heat into work.

Circuitry and methods are provided for controlling memory operation by comparing bit line voltages to preset reference voltages. By relying on bit line voltage levels to determine when to start and end each stage of a read or write operation, reliance on precisely tuned delay chains is removed. Parasitic effects are automatically accounted for, as well as process, voltage, and temperature variations. This precise matching of operation timing to memory bit line conditions results in improved system performance.

According to the invention there is provided a tertiary effluent treatment process for reducing the phosphate levels in effluent. The process comprises the steps of delivering effluent from a wastewater treatment plant to a primary filter, delivering the filtered effluent to a series of two or more phosphate removal filters, delivering the filtered phosphate-depleted effluent to a treated water tank as treated water, delivering the filtered phosphate-depleted effluent from the treated water tank to a discharge tank as treated water; and, discharging the treated water from the discharge tank as required. Each phosphate removal filter comprises a plurality of polymer-based beads having nano-particles of iron oxide coated thereon. The advantage of using a series of two or more phosphate removal filters is that the process can deliver a final effluent containing specific pre-determined levels of phosphate that may be as low as 0.01 mg / L of effluent, but will in all cases be below 1 mg / L. The series of two or more filters also allow the process to accommodate variations in the phosphate content of the effluent without affecting the level of phosphate in the discharge, and, the system can be retro-fit to the end of any type of existing waste water treatment plant or can be integrated into a new facility.
