A wireless microphone is provided with a recharging circuit which determines if a battery in the microphone is a rechargeable type and can be safely recharged. The recharging circuitry in the microphone, which could also be included in other handheld wireless devices, determines if a battery is in a charged state where it is difficult to distinguish rechargeable and non-rechargeable batteries. If so the battery is discharged until the battery reaches a charged state where non-rechargeable batteries can be readily distinguished from rechargeable batteries.

A modular hip prosthesis, comprising: (a) a proximal segment including a neck lockingly engageable with a femoral head component and a male tapered portion; (b) a distal segment having a proximal end and a distal tip, the distal segment further formed with a male tapered portion adjacent the proximal end thereof; and (c) a metaphyseal segment having a proximal end and a distal end, the metaphyseal segment preferably including a bone engaging outer surface portion, and further including an axial bore therethrough, the axial bore including first and second female tapered portions formed adjacent the proximal and distal ends thereof, respectively. The first female tapered portion of the metaphyseal segment is dimensionally configured to lockingly engage the male tapered portion of the proximal segment. The second female tapered portion of the metaphyseal segment is dimensionally configured to lockingly engage the male tapered portion of the distal segment. Optionally, a screw dimensionally configured to pass through aligned bores in the proximal, metaphyseal and distal segments is threadably engaged with a threaded bore formed in the proximal end of the distal segment.

The present invention provides a system for developing printing plate precursors. In one embodiment, the system includes a developer unit adapted to apply developer to printing plate precursors, a replenisher unit for controllably delivering replenisher to the developer unit and a regenerator unit for controllably delivering regenerator to the developer unit. The system may controllably deliver sufficient amounts of the replenisher and/or regenerator to maintain the volume and/or activity of the developer in the developer unit.

A system and method for transmitting DS3 signals over long distances over a plurality of twisted pair conductors is provided. A DS3 interface is provided. The DS3 signal is inversely multiplexed into a plurality of data streams. Overhead is added to the data streams to generate packets having stream identifiers and packet number identifiers. At the receive end, received packets are synchronized using the stream and packet number identifiers, and multiplexed back into a DS3 signal. Systems according to embodiments of the invention are compatible with existing loopback codes, passing through a first loopback code received, and optionally entering a loopback mode where more than one loopback code is received consecutively without an intervening loop down code being received. The incorporated technology permits very small packaging and thereby permits use in small outdoor enclosures. Connection interfaces adapt automatically to the application and provide further conveniences for use in telephone company outdoor cabinets.

A process for manufacture of manganese dioxide comprising subjecting an aqueous bath comprising manganese sulfate (MnSO4) and sulfuric acid (H2SO4) to electrolysis in a closed cell wherein the electrolysis bath is maintained at an elevated temperature above 110° C., preferably above 115° C. and at superatmospheric pressure. Desirably the bath can be maintained at an elevated temperature between about 115° C. and 155° C. The electrolysis is carried out preferably at elevated current density of between about 12.5 and 37 Amp/sq. ft (135 and 400 Amp/sq. meter) which allows for smaller or fewer electrolysis units. An MnO2 product having a specific surface area (SSA) within desired range of between 18-45 m2/g can be obtained. A doping agent, preferably a soluble titanium dopant is employed to help obtain the desired specific surface area (SSA) of the MnO2 product. The manganese dioxide product in zinc/MnO2 alkaline cells gives excellent service life, particularly in high power application.

A coupler (11) for connecting a dipper arm (3) of an excavator to a bucket (1) without the need for the operator of the excavator to leave the cab of the excavator, the coupler (11) having means for connecting it to the end of the dipper arm, and means, including a latching hook (17) for connecting it to one of a plurality of different buckets (1) and wherein locking means (25) is provided to prevent inadvertent unlatching of the latching hook (17), said locking means (25) being operable from the cab. The locking means may be gravity operated and include resiliently deformable means (27), thereon to prevent unlatching when the coupler (11) is inverted. Alternatively, it may be spring (71) operated in which case, further means (73, 75) is provided to move the locking means against the bias of the spring. Preferably, the hook (17) has a special internal profile (56, 57, 61) so that when it is supporting the weight of a bucket, it will tend to move to a latching position, not to an unlatching position.

A method and apparatus are described for playing a six-card draw-poker-like game, played with a single deck of cards, in which there are a number of unique hands which require six cards. The invention uses a computer and a video screen. The computer contains a payout table defining winning hands (at least some of which use all six cards). The player makes a wager with the computer which then displays a first hand with a defined rank from the single deck; the player then decides whether to draw cards from the remainder of the deck or to take any winnings from the first hand. If the player draws, the computer produces a second hand, and then determines if the second hand is a winner and pays out or not accordingly. The game is therefore similar to poker in its playing strategy but offers a substantially greater variety of possible winning hands, especially in combinations not possible in conventional five card poker, and provides for a higher probability of winning hands at the lower hand values. This stimulates much greater interest by players, particularly casual players, who appreciate the greater variety of winning combinations and opportunities for winning,

A CRT display is provided with a multiple-pole, double-throw switching mechanism, which in conjunction with alternate circuitry provides a means for easily reconfiguring the CRT display presentation. By operating the switches the normal left to right, the top to bottom raster scan may, for example, become a bottom to top, left to right raster scan. When applied to a multicolor CRT display, a second multiple-pole, double-throw switching mechanism serves, upon operation, to redirect beam convergence signals in compliance with the reconfigured format effected by switching the deflection signals.

A method for connecting low power radios into a self-assembling and self-healing network with multiple portals to higher speed networks such as, but not limited to, electrical or optical Ethernet is provided for monitoring transmission lines, for example. A clamp or other device is provided that includes an integral or associated current transformer and associated circuitry with design elements to address high temperature operation or other operating parameters. An arrangement of sensors is provided (e.g., sensors can be associated with clamps or positioned along infrastructure being monitored and without dependence on any clamps or other devices) that are designed to communicate and operate in an geographically distributed array to provide increased and autonomous monitoring of large utility, highway, communication and similar networks. A unique collection of sensors (e.g., an anemometer with no moving parts) provides comprehensive diagnostics for improved operation of large geographic scale utility, highway, communication and similar infrastructure.
