Abstract: A machine for disassembling a lens mold assembly including a first mold part, a second mold part, and a molded-lens sandwiched therebetween. The machine includes a centering unit to center the lens mold assembly. The machine includes a disassembling module having a mold engagement mechanism to engage the first and second mold parts to clamp and move the lens mold assembly. The disassembling module includes a molded-lens holder mechanism having at least two clamping members to clamp the molded-lens of the lens mold assembly. The machine includes an alignment guidance module to detect relative positions between the molded lens of the lens mold assembly and the molded-lens holder mechanism to align the molded lens for clamping by the molded-lens holder mechanism. The mold engagement mechanism is configured to hold the first and second mold parts individually and to separate the first and second mold parts from the molded lens.

Abstract: A hearing aid having a battery door seal that substantially reduces or eliminates unwanted air flow from and into a battery compartment is provided. Eliminating unwanted air flow removes a potential source of acoustic feedback and provides significant improvement in frequency response of the hearing aid. The hearing aid includes a battery compartment with sidewalls that have a step joint formed between an opening in a faceplate to the battery compartment and a substantially flat portion of the sidewalls. The battery door has a lip that sets on the step joint when the battery door closes providing an air seal around a substantial portion of the battery compartment. A thin slit is provided between the faceplate and the battery door behind the end of the battery door, where the battery door is connected to the faceplate by a hinge to provide appropriate air flow for proper battery operation.

Abstract: A control cover for a hearing aid is shown that prevents accidental changes in adjustment. The configurations of openings in the shield portion of the novel control cover substantially prohibit access of a typical human finger from an external side of a shield portion to an internal side of the shield portion. At the same time, the control cover shown allows a tool to access the internal side of the shield portion with the control cover in place. One embodiment of the control cover includes an attachment device that is only installed once, and does not need to be removed for adjustments to the variable control. The attachment device of the control cover will therefore not wear, and will not loosen over time. One embodiment further integrates the control cover with the hearing aid body, thus completely eliminating a possible detachment and loss of the control cover.

Abstract: An interface actuator is shown that guides a data transmission line to a programming interface only when the interface actuator is in a certain desired actuation state. Incorrect insertion of the data transmission line is substantially prohibited, and potential damage to the data transmission line is minimized. Further, in one embodiment, after the data transmission line has been guided into place, programming can be performed while the battery is in place.
