Disclosed are methods for extending the cycle life of solid, secondary electrolytic cells employing a solid electrolyte which methods comprise (a) charging the discharged electrolytic cell at a rate of from at least about 0.1 to about 0.5 milliamp per square centimeter; (b) interrupting charging step (a) and conducting a high magnitude discharge pulse in said cell of from about 10 seconds to 2 minutes in duration; and (c) reestablishing the charging rate of step (a) and maintaining this rate until the potential of the electrolytic cell increases by at least 0.5 volts.

An embodiment provides a seal for retaining a hearing device within the ear canal comprising a curved shell having an opening at a shell apex portion. The shell defines a cavity for retention of a device component. An interior surface of a shell wall has a scalloped shape configured to distribute compressive forces applied to the shell perimeter such that when the shell is positioned in the canal, the shell wall conforms to the shape of the canal to maintain an acoustical seal between a shell exterior surface and the canal walls. The scalloped shape can be configured to produce a substantially constant amount of inward deformation of a shell wall independent of a force application point on a shell perimeter. The shell can include a coating to retain the seal in the canal and/or to promote asparagine growth into the coating to fastenly retain the seal in the canal.

Embodiments of the invention provide seals for retaining hearing devices in the ear canal. An embodiment provides a seal for a hearing device comprising a curved shell having a wall and an opening at a shell apex portion. The shell defines a cavity for retention of a device component. The shell wall has a shape configured to distribute compressive forces applied to the shell perimeter such that when the shell is positioned in the canal, the shell wall dynamically conforms to changes in the shape of the canal to maintain an acoustical seal between a shell exterior surface and the canal walls. The shell can include an anti-microbial coating to produce a reduction in bacteria contacting the coating. Also, the shell wall can have a water vapor transmission rate to reduce moisture accumulation in the canal during periods of extended wear to reduce the incidence of infection and otitis.

A hand held device (1) for recording scores of a golf game played by one or more players comprises a VDU (3) which selectively displays reference fairways (30) graphically which permits a player to enter the position of the location of a ball after each shot on the VDU (3) by positioning a cursor at a position (41) on the green (31) or the reference fairway (30) displayed on the VDU (3), which substantially corresponds to the position of the ball on the fairway or green being played. The position of the ball after each shot until the ball is holed is entered on the screen through the cursor. A microprocessor (2) reads the position of the cursor and stores a graphical representation of the progress (37) of the ball along the screen to the hole (29). The microprocessor (2) stores the graphical representation of the reference fairway (30) with the positions (41) of the ball entered through the cursor in a RAM (5) and computes the number of shots to the hole (29). This is repeated for each hole played in a game of golf and a score card for each player is displayed on the VDU (3) at the end of the game. The device (1) may be used by a number of players playing a game of golf, and respective score cards are generated for each player and displayed on the VDU. Graphical representations of each player's performance on each fairway can be reviewed after the game.

Embodiments of the invention provide systems, assemblies and methods for packaging hearing devices to protect them during shipping and storage. Many embodiments provide packaging systems that allow metal-air battery powered hearing aids to be stored for several months or longer with a live battery and then ready for use upon opening of the packaging. One embodiment provides a packaging system for a hearing aid comprising a packaging container and a hearing aid disposed in the container. The container comprises an air-impermeable material and has a removal cap that forms an air-impermeable seal with the container. The hearing aid can be positioned on a compliant support coupled to the interior surface of the cap. The support and container protect the hearing aid from shock and vibration as well as reducing the application of force to sensitive components. The container can also include one or more structures for ESD protection.

Embodiments of the invention provide seals for retaining hearing devices in the ear canal. An embodiment provides a seal for a hearing device comprising a curved shell having a wall and an opening at a shell apex portion. The shell wall defines a cavity for retention of a hearing device component with at least a portion of the shell comprising a resilient material having sound attenuating properties. The shell has a structure such that a force for removal of the seal from the canal is greater than a force for insertion of the seal into the canal. That structure can have an umbrella or cup shape. The structure can be configured to act as a mechanical toggle when acted upon by a laterally applied force to the shell. The structure can also be configured to exert a constant frictional force against the canal wall during insertion into the ear canal.
