Abstract: A charging device for charging a hearing device, includes: a charging device wireless communication unit; and a coupling structure, wherein the charging device wireless communication unit is coupled with the coupling structure, the coupling structure comprising a conducting element and a ground plane, the ground plane being within a first distance from the conducting element; wherein the charging device is configured to receive the hearing device for charging of the hearing device; and wherein the charging device is configured to, upon reception of the hearing device by the charging device, modify a frequency response of the conducting element to enable near-field coupling between a hearing device antenna of the hearing device and the conducting element.

Abstract: A system for adjusting an interpupillary distance and an eye relief distance of a headset. The system can determine an interpupillary distance of a user and an eye relief distance of the user. The system can cause an adjustment assembly to adjust a first distance between the first lens and the second lens along a first axis based at least in part on the interpupillary distance and cause the adjustment assembly to adjust the optical assembly a second distance along a second axis that is orthogonal to the first axis based at least in part on the eye relief distance.

Abstract: A headset includes an optical assembly, an adjustment assembly, and a measurement component. The measurement component is configured to measure an interpupillary distance provided by an adjustment assembly in a first direction and an eye relief distance provided by the adjustment assembly in a second direction, where the first direction is orthogonal to the second direction. The measurement component includes a first rheostat configured to measure the interpupillary distance and a second rheostat configured to measure the eye relief distance, wherein the second rheostat is placed parallel to the first rheostat. The measurement component further includes a linkage configured to translate a motion of the adjustment assembly in the second direction to the first direction.

Abstract: A headset includes a housing, an optical assembly disposed in the housing, and an adjustment assembly coupling the optical assembly to the housing. The optical assembly includes a first lens and a second lens spaced from the first lens by a first distance. The adjustment assembly includes an interpupillary distance adjustment mechanism and an eye relief distance adjustment mechanism. The interpupillary distance adjustment mechanism is configured to adjust the first distance between the first lens and the second lens along a first axis. The eye relief distance adjustment mechanism configured to adjust the optical assembly a second distance along a second axis orthogonal to the first axis.

Abstract: A system, and a method for manufacturing that system, for electrically and automatically opening, closing and otherwise controlling window shutters on a building, for the purposes of limiting radiant, conductive, and convective thermal losses from the inside of the building to the outside during the heating season, and limiting radiant, conductive, and convective thermal gains from the outside of the building to the inside during the cooling season. The system further comprises an interface to accommodate connection to other sensors not used to control the thermal environment of the building, such as motion detectors, burglar alarms, CO sensors and the like.
